1 m2 of a field gets about 1050MJ of light energy per year. Only 21 500 kJ of energy is stored in the new grass.
How is the energy stored in the new grass?
Answers
Glucose is the form in which the energy is kept in the grass plant. Water and carbon dioxide are converted by plants into a sugar called glucose using the power of the sun.
Food is produced by plants through a process known as photosynthesis. Plants use their leaves to capture light energy during photosynthesis. Starch, a complex carbohydrate that can be converted into a simple carbohydrate (glucose) for the plant to use as fuel, is how plants store their energy. Like other cells, plant cells store starch (glucose) in storage organelles. Plants use glucose as a source of energy and to create other compounds like cellulose and starch. Plants, algae, and some bacteria carry out the process by utilizing sunlight to create oxygen (O2) and chemical energy that is stored in glucose.

Cytotoxic T cells release antigen that inform other white blood cells to fight the pathogen causing the infection.
Cytotoxic T cells release histamine molecules that signal the blood vessels to dilate.
Cytotoxic T cells release antibodies that neutralize antigens of pathogens.
Cytotoxic T cells release proteins that trigger infected cells to undergo apoptosis and/or cytolysis.
Answers
When a cytotoxic T cell is activated, they release proteins that trigger infected cells to undergo apoptosis and/or cytolysis. The given statement is the correct option.
Therefore, the correct option is: Cytotoxic T cells release proteins that trigger infected cells to undergo apoptosis and/or cytolysis.An immune response is a reaction that occurs in the human body against foreign substances and infectious agents such as bacteria, viruses, and fungi.
There are two types of immune responses: innate and adaptive. Adaptive immune responses occur when an immune cell recognizes a specific antigen. Adaptive immunity consists of humoral immunity and cell-mediated immunity. The latter is a type of immune response mediated by T cells. T cells come in two major types, namely helper T cells and cytotoxic T cells.Cytotoxic T cells are specialized white blood cells that eliminate infected or cancerous cells in the human body.

How do symbiotic relationships provide an advantage when organisms compete with each other in nature?
Answers
Symbiotic relationships can provide an advantage when organisms compete with each other in nature by allowing them to access resources that they may not have been able to obtain on their own.
For example, in mutualistic relationships, two organisms may work together to acquire food or nutrients that they could not obtain on their own. In commensal relationships, one organism may benefit from the other without harming or benefiting it, but still gain an advantage by accessing resources that the other organism is not utilizing.
These relationships can lead to increased survival, growth, and reproductive success, ultimately giving the organisms involved a competitive advantage over those that do not have such relationships.

The base units relevant to force are:
The metre, or m, is a unit of length.
The kilogram (kg), a unit of mass
second, or s, is a unit of time.
The change in momentum rate is referred to as force. This is comparable to mass x acceleration for a constant mass.
Therefore, 1 N equals 1 kilogram m s-2 or 1 kg m/s2.
Force is denoted by the letter F.
A force is an effect that can alter an object's motion in physics. A force can cause an object with mass to accelerate when it changes its velocity, for as when it moves away from rest. An obvious way to describe force is as a push or a pull. A force is a vector quantity since it has both magnitude and direction. It is calculated using the newton SI unit (N).

A plant's metabolism is affected by aerobic respiration in several ways. The rate of respiration can determine the rate of metabolism, as respiration provides the energy needed for metabolic processes to occur. Aerobic respiration also provides energy in a useable form, such as ATP, which can be used by the plant to power various cellular processes. Additionally, aerobic respiration is a source of necessary enzymes, which are needed for various metabolic reactions to occur.

what did griffit observe when he injected a mixturew of heat-killed, desease casuing bacteria and live harmless bacteria into mice
Answers
In his subsequent experiment, Griffith combined live, non-lethal bacteria from the R strain with heat-killed S-strain bacteria and administered the resulting mixture to laboratory mice. Many of the infected mice perished from pneumonia.
What did Griffith's study reveal about DNA?Griffith came to the conclusion that S strain bacteria had changed R strain bacteria based on his observation. The S strain bacteria were heat-killed, but the R strain gained a "transforming principle" from them that rendered them virulent.
What was established by the Griffith experiment?The first experiment to demonstrate that bacteria are capable of transferring genetic information through a process known as transformation was Griffith's experiment, which Frederick Griffith reported on in 1928.

Heredity, also known as inheritance or biological inheritance, is the transmission of traits from one generation to the next.
Each of your parents has two copies of each of their genes, and each parent passes on only one copy to you.

A team of scientists is studying a mitochondrial DNA sequence shared by two species, and they determine that the DNA has a constant mutation rate. The DNA sequences of the two species are shown below.
Species A: GTAGGCATTCGAT
Species B: GTAGGCATACGTT
Based on this information, which of the following best explains the difference in the DNA sequence between the two species?
Both differ by three mutations which means they have a close ancestor.
The constant rate of the mutation means that less time has passed.
Fewer differences in DNA lead to more mutations as time passes.
Species A and B are under pressure due to natural selection.
Answers
Answer:
The answer is B. The constant rate of the mutation means that less time has passed.
Explanation:
I took the test, and got this answer correct.
Both differ by three mutations which means they have a close ancestor.
What is mutation?The fact that the mitochondrial DNA sequence has a constant mutation rate suggests that the number of differences in the DNA sequence can be used to estimate the amount of time that has passed since the two species shared a common ancestor. In this case, there are three differences between the DNA sequences of Species A and B, which indicates that they have a relatively recent common ancestor.
If the mutation rate was not constant, it would be difficult to accurately estimate the amount of time that has passed since the two species diverged. Additionally, the statement that fewer differences in DNA lead to more mutations as time passes is incorrect, as the number of mutations in a DNA sequence is determined by the mutation rate and the amount of time that has passed since the last common ancestor. Finally, there is no information in the question to suggest that either species is under pressure due to natural selection.

What about species?A group of things that share the same kind and name: kind. A group of related organisms with the capacity to bear viable offspring that falls below the genus level and is designated by a two-part scientific name. A group of plants or animals that may reproduce together and have similar characteristics is referred to as a species.A collection of people with similar traits who can interbreed to create fruitful offspring is how species are frequently defined. Alpaca - Vicugna pacos are two examples. A group of creatures that can naturally reproduce with one another and generate viable progeny is sometimes referred to as a species. However, classifying a species can be challenging and even contentious. The billions of people on the planet now are all members of the same species, Homo sapiens.
