D.)Plant
I would really a appreciate if you would be so kind to tell me which one of thease words dose the meaning belong to please and thank u
Answer:
A.)Prokaryotic
Explanation:
Based on the organization of their structures, all living cells can be classified into two groups: prokaryotic and eukaryotic. Prokaryotic cells do not have a nucleus. The DNA in a prokaryotic cell is bunched up in the center of the cell.
This level of classification is the most specific and includes a group of individual organisms that resemble one another closely and are able to interbreed to produce fertile offspring.
Group of answer choices
species
kingdom
genus
domain
Answer:
species
Explanation:
According to the most widely used species definition, the biological species concept, a species is a group of organisms that can potentially interbreed, or mate, with one another to produce viable, fertile offspring.
This level of organization is the most specific and includes a group of individual organisms that resemble one another closely and are able to interbreed to produce fertile offspring is species
what is the level of organization in an organism ?Cellular organization is one of the characteristics of a living organism which states that each living organism is made up of a single cell or more than one cell.
It is made up of various components such as chemicals like micro molecule that form the macro molecule, at chemical level the structural composition are organized together to make cells
At Cellular level of organization form the tissue and it is complex to cell but simpler to organ which makeup of various together.
The cluster of interacting organs is necessary as the organ which are the structural level that individuals do the specific function.
Organs are gather together form organ system and it is a complex system made up of organs that are similar in their function.

Which of the following facts supports the argument that a pregnant cow should be fed more in its last trimester?
The placenta is formed by the end of the first trimester
The heart beats and organs are formed during the first trimester.
Teeth and fur develop during the second trimester.
Three-quarters of all growth occurs during the third trimester.
Answer:
Three-Quarters of all growth occurs during the third trimester.
Explanation:
D is the only option that has anything to do with the last trimester which is what the question was asking about. Furthermore, because so much growth is occurring during this time the cow will need more food to support this growth. So, D is the best option.
In fruit flies, a dominant gene, G, codes for the trait of gray body color. A recessive gene, g. codes for black body color. Two fruit flies mate to
produce offspring
GG
Gg
Offspring
Which prediction about the offspring's body color is based on the properties of genetic reproduction?
O A The offspring can only express the trait of gray body color.
OB. The offspring can only have genes for the trait of gray body color.
O c The offspring can express either the gray or the black body color trait
O 0. The offspring are equally likely to have genes for the gray or black body color trait.
The prediction about the offspring's body color is based on the properties of genetic reproduction, it can only express the trait of gray body color. The correct option is A.
What is the dominant and recessive gene?Recessive and dominant genes. Dominant/recessive interactions are the most frequent type of allele-allele interaction. When one (dominant) allele of a gene effectively outweighs the other (recessive) allele, the allele is said to be dominant.
Blood types and eye color are two instances of dominant/recessive gene interactions. Due to recessive inheritance, the disease can only be brought on by a pair of faulty genes. Carriers are individuals who have only one faulty gene out of the pair.
Therefore, the correct option is A. The offspring can only express the trait of gray body color.

Dr. Robert Hazen has worked to develop a hypothesis that explains
the origin of life on Earth. His work has focused on hydrothermal vents, which are cracks in the ocean floor. Water heated by molten rock beneath the crust escapes from these vents at very high temperatures, producing hot, high-pressure environments at the vents on the ocean floor.
In order to provide evidence that these vents may be areas where life originated, which of the following states a null hypothesis Hazen might have used to begin his research?
(A) Organic molecules were transported to the hydrothermal vents via a meteorite, thereby seeding them with precursors for more complex molecules.
(B) The temperatures and pressures found in hydrothermal vents resemble conditions described in currently accepted origins of life hypotheses.
(C) Organic waste sinking to the ocean floor would have used the unique hot water environment as an energy source to begin manufacturing food.
(D) Chemosynthetic organisms can best develop in the hydrothermal environment, manufacturing nutrients for other living things to feed on.
Answer:
(B) The temperatures and pressures found in hydrothermal vents resemble conditions described in currently accepted origins of life hypotheses
Explanation:
We are told that Dr. Hazen wants to develop a hypothesis that explains
the origin of life on Earth.
Now, he focused on hydrothermal vents. That Water heated by molten rock beneath the crust escapes from these vents at very high temperatures, producing hot, high-pressure environments at the vents on the ocean floor.
This means the null hypothesis will be temperatures and pressures found in this initial condition he described while any other different from it will be the alternative hypothesis.
Looking at all the given options and comparing with the initial hypothesis conditions in the question, the correct answer is option B.
The origin of life can be seen as the natural process in which the origin of living things happen through non-living matter or smaller organic compound.
The null hypothesis is:
(B) The temperatures and pressures found in hydrothermal vents matches the conditions described in currently accepted origins of life hypotheses.
The null hypothesis for Dr. Robert Hazen hypothesisThe hypothesis says that hydrothermal vents are cracks in the ocean floor.It also states that there were high temperatures and high pressure environment.Thus, the option (B) The temperatures and pressures found in hydrothermal vents matches the conditions described in currently accepted origins of life hypotheses is the best null hypothesis for Dr. hazen to begin his research.

Identify the phase of the moon labeled C that would be seen from the earth labeled B
Answer:
The correct answer is - a lunar eclipse (total lunar eclipse).
Explanation:
When the sun and moon align opposite one another and earth between them and blocks the light of the sun to reach the moon known as a lunar eclipse. A lunar eclipse can be a partial or total lunar eclipse.
A partial lunar eclipse occurs when a part of the earth covers the moon to get the light or between the sun and the moon. The total lunar eclipse occurs when the whole moon is opposite to the sun and earth between them.

Complete a model to explain the molecular events occurring at each stage of this reaction profile. Rank the stages from the first to the last one.
The substrate molecules are entering the cells, so no product is made yet As the substrate is used up, the rate decreases (the slope is less steep)
The line is flat because no new substrate remains and thus no new product appears
There is sufficient substrate, so the reaction is proceeding at a maximum rate
Section A Section D
Answer:
The substrate molecules are entering the cells, so no product is made yet.
There is sufficient substrate, so the reaction is proceeding at a maximum rate
As the substrate is used up, the rate decreases (the slope is less steep)
The line is flat because no new substrate remains and thus no new product appears
Explanation:
First the substrate molecules enters in the cell and no product is produced because the reaction is not started yet. When the reaction starts, the substrate is in large amount while on the other hand, the amount of product is low. As the reaction proceed forward, concentration of substrate is lowering and concentration of product is increasing. When all the substrate used up, so no new product is formed.
Based on the Resource Use and Conservation Virtual Lab, Which tactic can do the most to keep the water debt less than the water supply?
A. Outlawing water features in gardens
B. Replacing drip irrigation systems
C. Outlawing drip irrigation systems
D. Replacing thermal power plants.
Answer: D. Replacing thermal power plants.
Explanation:
Thermal Power Stations are some of the biggest users of water in the world because water is integral to producing electricity in them. These stations burn fossil fuels like coal which then vaporizes water so that it becomes steam which then drives turbines that produce electricity.
Water is also used for cooling high temperatures produced.
If these thermal stations are replaced with something that uses less water, it will go a long way in keeping the water debt less than the water supply.

Select the two correct statements. Select the two correct statements. All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.
Complete question:
Comparisons of amino acid sequences can shed light on the evolutionary divergence of related species. If you were comparing two living species, would you expect all proteins to show the same degree of divergence? Select the two correct statements.
All proteins will show the same degree of divergence because they are modified with the same rate of evolution. All proteins will show the same degree of divergence because different species experience the same selection pressure. All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. All proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism.All proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism.Answer:
3) All proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure.
4) All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways.
Explanation:
All proteins will show the same degree of divergence because they are modified with the same rate of evolution. FALSE. All proteins will show the same degree of divergence because different species experience the same selection pressure. FALSEAll proteins will show different degrees of divergence because different species live in different habitats and experience different selection pressure. TRUE All proteins will show different degrees of divergence because different species exhibit different patterns of behavior and have different metabolic pathways. TRUEAll proteins will show the same degree of divergence because all cellular functions are essential to the survival of the organism. FALSEAll proteins will show different degrees of divergence because some cellular functions are more essential than others to the survival of the organism. FALSE.In this example, we are comparing different species, although we do not know how different they are. Changes in the proteins reflect the divergence between groups during evolution. Among different animals and plants, changes in proteins and their following maintenance can be associated with a group divergence and evolution.
The same proteins amino acid sequences in different species provide information about the divergence point between both species. Probably, the origin of genes and protein changes and the subsequent fixation of those changes by natural selection is the cause of most of the phenotypic variation observed between species. So, genes and proteins are subdued to selective pressures that vary according to the environment and the species.
In populations of the same species inhabiting different places with different environmental characteristics suffer changes that respond to their life habits. Proteins evolve in different degrees and take different routes, influenced by the selective pressures of the environment surrounding them. Ecological, behavioral, reproductive pressures, among others, vary between populations according to their own needs and produce changes that "model" the organisms when fixating. These changes are inherited generation after generation, leading to a divergence in the species.

Limestone form as ocean water evaporates and leaves calcium carbonate behind, which is the deposited in the seabed. What type of rock can be formed this way?
Answer:
Sedimentary rock.
Explanation:
Limestone form as ocean water evaporates and leaves calcium carbonate behind, which is then deposited in the seabed. Thus, the type of rock that can be formed this way is a sedimentary rock.
The texture of inorganic land-derived sedimentary rocks is fragmental or clastic. Sediments come from land to form inorganic sedimentary rocks.
Some examples of inorganic land-derived sedimentary rocks are conglomerate, brescia and sandstone.
