Answer:
The correct answer is -
1. Archaea are prokaryotic cells. These are one of the two prokaryotic organism domain. the other is eubacteria.
2. Eubacteria cell wall contains peptidoglycan which is composed of sugar and amino acids.
3. Eukaryotic cells have membrane-bound nucleus or organelles. which distinguishes it from prokaryotic cells.
4. All archaea domain organisms found in extreme conditions such as halophiles, extremophiles, and thermophile.
5. The cell wall of the plant is made of cellulose, a polymer of glucose units.
6. Eubacteria are considered to be the first living organism or form found on earth.
7. Fungi cell walls are made up of a chitin cell wall. which is makes it different from eubacteria and plants.
8. Fungi uses absorption to obtain nutrients. Most of the fungi uses haustaurium to absorb nutrients.
9.Fungi are organism that do not fit in other eukaryotic category. Hence they were classified as separate kingdom in 5 kingdom classification.
10.plants are classifies as autotrophs because they make their own food.These autotrophs serve as primary producers.
11.Corals have a symbiotic relationship with algae. Algae provide food for coral through photosynthesis where as coral provide protection to algae.
12.corals are classified as autotrophs due to their relationship with algae.They are mixotrophs generally because they act as autotrophs with association of algae and capture prey by tentacles thus making heterotrophic nutrition.
6. How might protein synthesis execute differently if a mutation occurs?
Answer:
The wrong protein can be created or the right one with abnormal function.
Explanation:
The mutated DNA is taken through the whole protein synthesis process and translated by the rRNA and tRNA to create a protein from that new sequence.
How does competition affects behavior of species
Answer:
The way organisms compete with each other determines species distributions, population dynamics, community structure, food webs, and social dominance hierarchies. ... These stressors affect the way that organisms compete with each other and their ability to survive and co-exist.

Which factors were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection?
(1 point)
1. a change in the diet of human populations as they settled in colder climates
2. the clothing worn by humans in the early 8th century
3.the interaction of human populations with predators in colder climates
4.the impact of UV radiation on folate and Vitamin D levels in human populations
Answer: The answer is 4
Explanation:
Vitamin D controls your skin pigment. It's kind of like when someone has an iron deficiency they get bruises and they turn a whiter shade.
Hope I helped :)
The factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection are the impact of UV radiation on folate and Vitamin D levels in human populations.
Ultraviolet B radiation produces diet D in human skin. Ultraviolet radiation can, however, smash folate. Folate is critical for the speedy increase of cells, particularly at some point in which its deficiency can motivate neural tube defects. The human frame additionally has a mechanism to save you overproduction of vitamins.
What is UV radiation?Ultraviolet is a shape of electromagnetic radiation with a wavelength from 10 nm to four hundred nm, shorter than that of seen light, but longer than X-rays. UV radiation is found in sunlight and constitutes approximately 10% of the whole electromagnetic radiation output from the Sun.
Thus it is learned that the above answers are well-explained factors that were determined to directly cause the loss of skin pigmentation in humans as a result of natural selection bout.

Which material heats fastest, the rock, the sand or the water?
Explain your answer.
Answer:
Sand
Explanation:
Sand heated up faster than water because sand is darker than water; dark-colored materials will absorb more light. Sand heated up faster than water because sand is a solid and water is a liquid. Water is a slow conductor of heat, thus it needs to gain more energy than the sand or dry land in order for its temperature to increase. On the other hand, soil loses its heat much faster. Water has to lose more energy than the sand (dry land) in order for the temperature to decrease.

A group of researchers are studying stem length inheritance in the garden pea plant (Pisum sativum). They obtain a tall pea plant of unknown ancestry, allow it to self-pollinate, and collect 80 of its seeds. After planting the seeds, they observe the growth of 61 tall plants and 19 dwarf plants. Which of the following best explains the stem lengths seen in the offspring?
A. Stem length is inherited through incomplete dominance.
B. Dwarf stem length is a recessive trait.
C. Stem length is a sex-linked trait.
D. The tall plants likely received more nutrition than the dwarf plants.
Answer:
The answer is B
Explanation:
just cause lol
The study of a living being is called biology.
The correct answer is B.
The characters in the plant are controlled by the genes which are present on the chromosome. The genes are always present in pairs and a single gene is known as an allele. The alleles are as follows:-
DominantRecessive.According to the question, most of the offspring are tall in height due to the dominant allele while the number of the dwarf plant is less as this character is shown by the recessive genes.
The dominant plant suppresses the character of a recessive gene and hence the number of the dominant plant is always more.
Hence, the correct answer is B. Dwarf stem length is a recessive trait.

A farmer often sprays a certain kind of insecticide, a chemical that kills insects, on his plants to prevent locust bugs from eating all of his corn crops. One day there was a random change in the sequence of DNA in a locust egg cell. When the egg cell hatched, the locust was resistant to the insecticide (it would not be killed by it). Since that locust could survive and reproduce, natural selection occurred until the entire population evolved to become resistant.
A) Identify the variation that existed in the insect population. _________________________________
B) Identify the process that created this variation. _________________________________
C) Explain why the variations in the insect population would be passed on to the next generation.
D) Is this locust population likely to survive, why or why not?

On your Spring Break in Mexico, you take a break to count the starfish in a tidal pool. You notice that there is a rare recessive trait that causes the starfish to have 6 legs instead of 5. Of the 27 starfish you can find, only 1 has 6 legs. What are the allele frequencies for this population
Answer:
0.04 for 6 legs starfish and 0.96 for 5 legs starfish.
Explanation:
The allele frequency for the 6 legs starfish is 0.04 whereas, the allele frequency for the 5 legs starfish is 0.96 because there is only one 6 legs starfish in the given population as compared to 5 legs starfish. The low population of 6 legs starfish is due to the presence of recessive allele while on the other hand, higher population of 5 legs starfish is due to the presence of dominant allele. The allele frequencies for both population is done by dividing the allele of interest by total number of alleles present in the population.

Sometimes an organ can be replaced by moving it from one part of the body to another. This can be done, for example, to replace damaged skin or joints. In these cases: rejection of the transplanted organ would not be expected. antibodies would be generated against the transplanted organ. antigens would be generated against the transplanted organ. immunosuppressant drugs would be required to prevent transplant rejection. rejection of the transplanted organ would still be expected.
Answer:
rejection of the transplanted organ would not be expected.
Explanation:
Organs can be defined as specialized body tissues united to perform specific functions in living organisms. Some examples of organs found in humans are brain, bladder, kidney, heart, intestine, eyes, lungs, liver, etc.
In the field of Medicine and Surgery, an organ is sometimes replaced for specific reasons, by moving it from one part of the body to another; this process is generally referred to as a transplant. Thus, it's mainly done to replace damaged skin or joints in the body of a living organism such as humans.
Hence, in these cases, rejection of the transplanted organ would not be expected because an examination and matching of the organ is carried out by the medical professionals before transplant.
