Answer: B. The nitrogen compounds were absorbed by seedlings for their growth.
Explanation:
For the plant to have energy accessible when and where it needs it to maximize yield, nitrogen is essential. As proteins and enzymes control water and nutrient intake, this important nutrient is even present in the roots. Thus, option B is correct.
What nitrogen compounds were absorbed by the seedlings?Plants absorb ammonium and nitrate during the assimilation process, and these substances are then converted into organic molecules containing nitrogen, such as DNA and amino acids.
Plants may absorb substances from soils like nitrate, nitrite, ammonia, and ammonium, which are subsequently utilized to create proteins in both plants and animals.
Therefore, The nitrogen compounds were absorbed by the seedlings for their growth. After they reach three inches in height, seedlings should be fertilized; after that, they can get weekly fertilization until being transplanted.

Why do we exhale more carbon dioxide than we inhale?
Answer:
When we exhale, we breathe out less oxygen but more carbon dioxide than we inhale. The carbon we breathe out as carbon dioxide comes from the carbon in the food we eat. The carbon dioxide is dissolved in the blood, carried to the lungs by the circulation, and breathed out.
Answer:
because our bodies take in O and put out CO2
Explanation:
O is Oxygen
and CO2 is Carbon dioxide

What is the volume of a square pyramid with a base edge of 14 m and a slant height of 25 m
Answer:
length of base(l) = 14m
slant height (s)=25m
we know,
slant height(s)=√(l/2)^2 + h^2
or, 25= √(14/2)^2+ h^2
or, 25 = √49+h^2
or, 25^2 = 49+h^2
or, 625 = 49 + h^2
or, 625-49=h^2
or, √576 =h
h=24
Therefore vertical height (h)= 24m
Again,
Volume of square pyramid (v) = 1/3 L^2h
or, v =( 1/3) 14^2×24
or, v= 4704 / 3
Therefore, V= 1568 cubic meter.

When there is no pattern to a
population's growth, it is known as
A. irregular
B. stable
C. irruptive
D. cyclical
When there is no pattern to a population's growth, it is known as stable. The correct option is B.
What is population growth?The rise in the number of people on Earth is referred to as population growth. The majority of human history saw a relatively steady population size. Energy, food, water, and medical care, however, became more accessible and dependable as a result of innovation and industrialisation.
The predicted population expansion is due in part to factors like an increase in young, unmarried mothers, high fertility rates for specific ethnic groups, and a lack of access to contraception and sexual education.
When age-specific fertility and mortality rates are constant over a long period of time, there is a stable population growth.
Contrarily, an irregular population increase is one in which there is no structure and the population size behaves chaotically.
Thus, the correct option is B.

how most of our excretory system is not dedicated to excreting; it’s dedicated to reabsorbing.
Answer:
Not all animals use the same routes or excrete their wastes the same way humans do. Excretion applies to metabolic waste products that cross a plasma membrane.
The excretory system works with the respiratory, endocrine, urinary and digestive system. It works with the respiratory system because it helps the lungs get rid of carbon dioxide and water vapors. It works with the digestive system to help get rid of wastes that you eat through the anus.

____ The diaphragm contracts and flattens
____ The muscles between the ribs contract to move the ribs up and out
Answer:
air is drawn into the lungs
lungs expand
the muscles between the ribs contract to move the ribs up and down
air pressure in the chest cavity decreases
the diaphragm contracts and flattens
Inhalation has been part of respiration. It includes drawing air into the lungs that expand the lung cavity by pulling the ribs leading to contracting the diaphragm followed by a decrease in lung pressure. Thus the correct order is 1, 3, 5, 4, and 2.
What is inhalation?Inhalation is the respiratory process to inhale oxygen inside the respiratory system for the cellular and respiratory processes. At first, the air is drawn into the lungs followed by expansion of the lungs.
This causes the ribs muscles to move up and down to accumulate the volume. This movement causes the diaphragm to flatten and contract which allows the oxygen to take place in the lungs that decreasing the air pressure in the cavity.
Therefore, the air is drawn inside the lungs in inhalation.

why do large organisms require a transport system?
Answer:
Larger animals have a lower surface area to volume ratio. This means they need transport systems like our circulatory system and exchange surfaces like our lungs or fish gills. In single-celled organisms such as protists, and small multicellular organisms, essential molecules will move to where they're needed by diffusion.
Explanation:
Answer:
As the size of an organism increases, its surface area to volume ratio decreases. ... Large multicellular organisms therefore cannot rely on diffusion alone to supply their cells with substances such as food and oxygen and to remove waste products. Large multicellular organisms require specialised transport systems.

The diagram below shows two processes, P and Q, in the carbon cycle.
Which of these statements best describes the processes P and Q?
P shows diffusion and Q shows weathering.
P shows weathering and Q shows diffusion.
P represents combustion and Q represents decomposition.
P represents decomposition and Q represents combustion.
Answer:
P shows diffusion and Q shows weathering.
Explanation:
The process shown in the image attached to this question is a part of the carbon cycle. Based on the image in this question, atmospheric carbon enters the ocean in a process called P while carbon deposited in limestone is released into the atmosphere via a process called Q.
- Atmospheric carbon which is carbon dioxide (CO2) enters the surface of the ocean via a process called DIFFUSION, hence, process P shows diffusion
- Also, for the carbon in limestone to be released into the atmosphere, the limestone has to be broken down in a process called WEATHERING. Hence, process Q shows weathering.

in pea plants, purple are dominant to white.
complete the chart showing the genotypes and phenotypes possible.
someone help me i’m kinda lost on how i do this
Answer:
PP (genotype) - Purple (Phenotype)
Pp (Genotype - Purple (Phenotype)
pp (Genotype) - White (Phenotype)
Explanation:
The genotype allele combinations, in order to for purple to be dominant there are three possible genotypes
*Capital P represents a purple dominant allele
*Lowercase p represents a white recessive allele
(Alleles are the variants of a certain gene, ex: brown eyes, green eyes, etc. )
A Dominant always overpowers the recessive, the only way for a recessive to show would be to have two recessive alleles from both parents
ex: Green eyes recessive to Brown
B - Brown bb = green eyes (from dad)
b - green bb = green eyes (from mom)
this means that their child would have green eyes because there is no brown present
So for your pea plants to be purple
Pp = Purple pp = white
PP = Purple (yes there can be white recessive present, it just might not appear as a plant because of the percent of purple)
The colors or observations we see as the plant are the phenotypes
so the colors I have listed would be the phenotypes
Don't get alleles and phenotypes confused, alleles are the various forms of a gene, and phenotypes are what we see when the gene is brought through.
(b) Identify the dependent variable in the experiments. Identify a control group missing from the second experiment. Justify the need for this control group in the second experiment.
Hello. You have not submitted the experiments to which this question refers, which makes it impossible for it to be answered. However, I will try to help you in the best possible way.
A dependent variable is one that is influenced by an element, in order to present a result, that is, it is a variable that does not establish itself, being dependent on another variable to establish itself. An example of a dependent variable can be seen in an experiment that seeks to determine the differences in growth rates of bean plants that were fertilized with different organic fertilizers. As you can see, this is an experiment where the different organic fertilizers influence differences in the growth rate of bean plants. Thus, the growth of these plants depends on the fertilizer, this growth being the variable dependent on the experiment.
A control group, in turn, is an element of the experiment that does not receive the element that is being tested in the same experiment. The control group is important, because it allows the researcher to see the results of a system where the tested element does not exist, thus being able to determine the real differences that the tested element is capable of causing. Using the same example presented in the paragraph above, we can see that the different organic fertilizers are the elements tested in the experiment. These fertilizers will be applied to the plants, however it is important that at least one of these plants does not receive any fertilizer, so that the difference between a system with fertilizer and a system without fertilizer can be evaluated. This plant that received no fertilizer is the control group.

Explanation:
Which is of the following is necessary for natural selection? 1. There must be a shortage of food 2. There must be a change in the environment, causing individuals to change 3. There must be some genetic differences among the individuals of a species 4. all of the above
Answer:
It's 3!
Explanation:
There must be genetic differences so the best fitted organisms will survive. If they were all the same then no one would be best fitted and Natural Selection wouldn't be able to occur
It's not 1 because a food shortage isn't required, there's always competition for food sources
It's not 2 because there doesn't need to be a change in the environment for natural selection, just for evolution.
And it can't be 4 if 1 and 2 are wrong!
