Answer: It produces pollen for preproduction
Explanation:
An anther of a flowering plant help in the survival of its species by producing pollen for reproduction. Thus, the correct option for this question is B.
What is the function of the anther in flowering plants?The fundamental and the most important function of the anther is to produce and provide the pollen, the pollen-containing anther acts as the sperm that is necessary for reproduction. It is characterized as a male reproductive part of a flower.
Apart from the anther, the Stigma is the female reproductive part of a flower. The connection of these two attributes may an essential role in reproduction. The anthers are bilobed with sac-like structures (microsporangia) present inside them. The stigma is a receptive base on which the pollen lands.
Therefore, a flowering plant's anther helps its species survive by producing pollen for reproduction. Thus, the correct option for this question is B.

equation of gaseous exchange in plants
Answer:
See the answer below
Explanation:
Gaseous exchange in plants involves the entering of oxygen and the exit of carbon dioxide in its place. It is an important process that helps sustains the life of plants, just like every other living organism. The oxygen that enters is utilized in the process of respiration during which carbohydrates are broken down to unlock their energy for metabolic activities.
Oxygen usually diffuses-in through the stomata while the carbon dioxide diffuses in the opposite direction. The summary of the gaseous exchange is summarized in the equation below:
Glucose (food) + Oxygen ---------> Carbon dioxide + water + energy
Or better still;
[tex]C_6H_1_2O_6 + 6O_2 --> 6CO_2 + 6H_2O + ATP[/tex]
Which of these is a distinguishing characteristic that can be inherited? *
A. gene
B. cross
C. punnett square
D. heterozygous
Answer:
a. Gene
Explanation:
Gene is a distinguishing characteristic that can be inherited. Therefore, option A is correct.
What are genes?The fundamental structural and operational component of heredity is a gene. DNA is the component of genes. Some genes serve as blueprints for the synthesis of proteins. A gene is actually pretty unremarkable in terms of its physical appearance. Essentially, it resembles any other bit of DNA. They form our genotype and decide our phenotype.
The 23 pairs of chromosomes in cell nuclei plus a tiny DNA molecule present in each mitochondrion make up the human genome, which is a full set of nucleic acid sequences for humans. There are two types of genes that are coding genes and non-coding genes.
Gene is a distinguishing characteristic that can be inherited. Therefore, option A is correct.

Why do candles extinguish when a lid is closed?
Answer:
fire needs oxygen to burn, when you take that oxygen away by putting a lid on it the fire goes out.
Explanation:
Answer & Explanation:
candles extinguish when a lid is closed because fire needs oxygen to sustain its energy so when the lid is closed no oxygen is coming in, so the candles with the fire slowly extinguish
Which statement about infiltration is TRUE? Group of answer choices groundwater is an unsafe (dangerous) source of water not meant for drinking Groundwater can remain in subsurface storage for long periods of time groundwater can NEVER return to the surface groundwater will ALWAYS discharge into a body of water
Answer: Groundwater can remain in subsurface storage for long periods of time.
Explanation:
The ground water is the water reservoir that gets accumulated beneath the earth crust due to the accumulation of water that seeps into the soil and rock due to the absorption by water bodies river, lakes, ponds, oceans, and rain or any kind of precipitation. The groundwater remains as a subsurface storage of water until the site of groundwater is searched and water is extracted from it for household, agricultural or industrial purposes.
TRUE OR FALSE: Phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc. In fact, any phospholipid may be called a "cellular tourist" because it is able to move about to virtually any part of a cell and can even become a part of a cell in a different region of the body! (EXPLAIN WHY)
Answer:
False, because phospholipids are a type of lipids and the nuclear envelope contains nucleic acids.
Explanation:
Hope this helps.
It is true that phospholipids that are a part of the nuclear envelope (membrane around the nucleus) can easily move from one part of the cell to another, and may ultimately become part of the cell membrane, the ER, a vesicle membrane, etc.
What is nuclear envelope made of?The nuclear envelope is made up of two concentric lipid bilayer membranes separated by a 20-40 nm intermembranous space.
In many places, the outer membrane is joined to the rough endoplasmic reticulum. The outer membrane of the nuclear envelope, like the rough ER, is dotted with ribosomes.
The nuclear envelope is made up of two membranes: an outer and an inner phospholipid bilayer. The lumen of the rough endoplasmic reticulum is connected to the thin space between the two layers (RER).
Nuclear pores, which are small channels that run across the nuclear envelope, allow substances to enter and exit the nucleus.
Each pore is lined by a group of proteins known as the nuclear pore complex, which regulates which molecules can enter and exit.
Thus, the given statement is true.

How does the process of natural selection account for the diversity of organisms that Darwin observed on the Galapagos Islands?
Answer:
Since each island is very different, birds from each of these islands all have different beaks, colorations, and sizes depending on the natural environmental factors surrounding their island.
Explanation:
I would also add in how birds had to adapt with different beak lengths and sizes in order to be able to get the food type that was most abundant. Natural selection was abundant in this case if one food source (say small seeds) was scarce, a bird with a small beak 1. Had very little if no small seeds to eat and 2. If there were large nuts that required breaking open (ability with birds for larger beaks to do so), the small bird could not break them open and then would unfortunately probably starve to death. Thus, natural selection occured so the birds with the large beaks were able to carry on their traits while the birds with the small beaks did not have as great of an opportunity (if not opportunity) to carry on their traits.
Since each island is very different, birds from each of these islands all have different beaks, colorations, and sizes depending on the natural environmental factors surrounding their island.

Explanation:
frank has type A blood (AA or AO) and margarita has type B (BB or BO) blood. They have a new baby. Vinnie, with type O blood. Is this possible or should frank accuse margarita of cheating?
Answer:
It is technically possible, if and only if, both parents have AO and BO blood.
Explanation:
the only way (most of the time) a child can get O blood is if both genes accepted by the parents are O. That would mean both parents would have to have O recessive genes.

(brainliest if right!) How is the dispersive model different from the semiconservative model of DNA replication?
1. In the dispersive model, each strand of both daughter molecules contains a mixture of old and newly synthesized DNA, and in the semiconservative model, each new double helix consists of one old and one new strand.
2. In the dispersive model, the old double helix is degraded, and in the semiconservative model half of its nucleotides are used in the construction of two new double helices.
3. In the dispersive model, one of the two resulting double helices is made of two old strands, and in the semiconservative model the other is made of two new strands.
4. In the dispersive model, one strand of the new double helix is made of DNA, and in the semiconservative model the other strand is made of RNA.

The correct answer would be - option C. the time that it takes you to get to the school.
Explanation:
The dependent variable is the factor or variable in any research or experiment is the variable that depends on the independent variable which means it changes with the change in the independent variable.
Here the time the different vehicle takes to get to the school is a dependent variable as it depends on the fact that which vehicle is using and changes with the change in the type of vehicle.
