Answer:
The correct answer is A, C, and D only.
Explanation:
A neurotransmitter is a biomolecule, generally synthesized by neurons, which is poured from vesicles in the presynaptic neuron into the synaptic gap and produces a change in the action potential of the postsynaptic neuron. Depending on the nature of the neurotransmitter, this can be synthesized in the neuronal soma or in the nerve endings. Some neurotransmitters are synthesized directly in nerve endings thanks to enzymes that have been synthesized in the soma and transported to these endings. Through the interior of the axon flows a current of substances free or enclosed in vesicles, which can be precursors of both neurotransmitters or their enzymes, called axonal flow.Another characteristic of the transmitter function in each of the substances commonly accepted as neurotransmitters is that when administered exogenously as a drug that in reasonable concentrations perfectly mimics the effects of the endogenously released transmitter.
Neurotransmitters should be defined by four essential characteristics. It involved the A, C, and D only.
What are Neurotransmitters?Neurotransmitters refer to the chemical messengers in the body that should transform the message from the nerve cell. Also, it should be synthesized in neurons and stored in the presynaptic terminal. It should be the vital attribute at the time when the chemical should mimic the activity of endogenous due to which it gets a similar response. Also it eliminates the activation site.

Which of the following statements about the structure of DNA is true?
A) It contains adenine, uracil, guanine, cytosine, and phosphorus.
B) It is composed of phosphates, nitrogenous bases, and ribose sugars.
C) It is composed of a single strand that consists of deoxyribose and phosphate.
D) It contains adenine, thymine, guanine, cytosine, and deoxyribose sugar.
Answer:
D
Explanation:
dna does not contain uracil. (uracil is in RNA)
dna does not have ribose sugars (ribose sugars are in RNA)
dna is not a single strand.
dna contains adenine, thymine, guanine, cytosine, and deoxyribose sugar.
DNA is a double stranded molecule. It has two strands of deoxy ribose sugar and the phosphorus groups where the H and OH bonding is present as well. It contains A,T,C and G. 4th option is correct.
What is the the full form of DNA ?DNA stands for deoxyribonucleic acid. It is made up of nucleic acid comprised with the sugar at which O is removed at the 2nd position.
DNA is double stranded in nature. The strand one of between the two strands where the first is called as template strand and the other one is called as coding strand. DNA copies DNA and the process is called as replication. DNA replication unit must have one ori that is origin of replication, promoter that is mostly attached at the 5' end of the strand.
The unit continues to add on bases in order to make the strand until the synthesis is complete. The nitrogenous bases of DNA are A,T,C and G where A stands for adenine, T for thymine, C for cytosine and G for guanine.
Therefore only option D is correct.

1. **In the procedure shown below, a calcium chloride solution is mixed with a sodium sulfate solution to create the products shown. Which of the following is illustrated by this activity?
a. The law of conservation of mass
b. The theory of thermal equilibrium
C. The law of conservation of energy
d. Newton's 2nd Law
The reaction follows the law of conservation of mass since the mass remains same before and after the reaction. Therefore, option (A) is correct.
What is the law of conservation of mass?According to the principle known as the rule of conservation of mass, during a chemical reaction, mass can neither be created nor destroyed. When coal is burned, for instance, the atom of carbon that it contains transforms into carbon dioxide. The mass of the carbon atom remains constant even as it transforms from a solid structure to a gaseous state.
The study of chemical reactions, as well as their generation, places a significant emphasis on the principle of mass conservation. Scientists are able to make accurate forecasts regarding the amounts of products that will be produced from a certain reaction if they are aware of both the amounts of reactants and their identities.
Thus, in the above reaction the mass is conserved and option (A) is correct.

Which option identifies the land stewardship issue of most concern in the following scenario?
The weather this year has been unusually dry; nevertheless, the number of cattle in the herd has increased.
wildfire control
erosion control
disease control
water conservation control
Answer:
wildfire control
Explanation:
Cattle grazing has been used as an effective wild fire control. On a yearly basis, grazing can reduce the amount and alter the continuity of fine fuels, potentially changing wildfire fire spread and intensity (Stand et al., 2018).
Historically, however, grazing pressure was one of greatest tools for reducing fine fuels that carry wildfires (Miller et al., 1994).
Livestock are very important in reducing the risk of wildfire because they remove the fine fuels; this removal of fine fuels by livestock grazing results in less occurrences of fire hazards.
Answer:
the correct answer is "erosion control"
Explanation:
The correct answer is erosion control. A high animal load on grasslands experiencing drought can lead to serious erosion problems. This situation can be exacerbated if winds remove topsoil; combined with overgrazing and drought, any new moisture could further the erosion of the soil.

Y gene R gene Precursor substrate Intermediate substrate Product and lacks color and fruit is and fruit is yellow fruit is red green from chlorophyll Mutations in the genes for both of the enzymes produce lack-of-function, recessive alleles. What would be the expected genotypic and phenotypic segregation ratios if you self-fertilize a RrYy individual
Answer:
Explanation:
From the information given:
The analysis of the hypothetical pathway gives:
Y gene R gene
Green fruit → Yellow fruit → Red fruit.
If RrYy undergoes self-fertilization, the expected genotypic and phenotypic segregation is:
RrYy × RrYy
The progenitors to undergo the segregation are as follows:
RY Ry rY ry
RY RRYY RRYy RrYY RrYy
(red) (red) (red) (red)
Ry RRYy RRyy RrYy Rryy
(red) (green) (red) (green)
rY RrYY RrYy rrYY rrYy
(red) (red) (yellow) (yellow)
ry RrYy Rryy rrYy rryy
(red) (green) (yellow) (green)
Thus; the expected phenotypic ratio is:
= 9(red) : 3(yellow) : 4(green)
The expected phenotypic ratio is:
= 1(RRYY): 2(RRYy): 2(RrYY): 4(RrYy): 1(RRyy): 2(Rryy): 1(rrYY): 2(rrYy): 1(rryy)

Describes three types of stimuli that cause plants to exhibit tropism.
Answer:
The three stimuli that cause the plants to exhibit tropism are:
1. Touch: This stimulus triggers thigmotropism, which is the turning or bending of the plant and tendrils in response to the touch.
2. Light: This stimulus triggers phototropism. It is how the plant reacts toward the direction of the light source. In this case, the stem may bend in response to the direction of the light.
3. Gravity: This stimulus triggers phototropism gravitropism, which is responsible for the downward growth of roots into the soil.
The three stimuli that cause the plants to exhibit tropism are: Touch, light and gravity.
What is Tropism?
Tropisms are biological occurrences that signify the expansion or rotation of a living thing, typically a plant, in response to environmental stimuli. Tropisms are frequently connected to plants (although not necessarily restricted to them).
Movement or activity in response to a particular stimulus is more likely to be viewed by an organism where it is capable of purposeful physical movement (motility).
1. Touch: This stimulus triggers thigmotropism, which is the turning or bending of the plant and tendrils in response to the touch.
2. Light: This stimulus triggers phototropism. It is how the plant reacts toward the direction of the light source. In this case, the stem may bend in response to the direction of the light. 3. Gravity: This stimulus triggers phototropism gravitropism, which is responsible for the downward growth of roots into the soil.

Which of the following molecules are needed for photosynthesis?
Answer:
Carbon dioxide and oxygen is needed for photosynthesis, and water if you have the choice.
Explanation:
The molecules needed for photosynthesis are carbon dioxide and water.
What is photosynthesis?Photosynthesis is a process performed by green plants where they are able to synthesize their own food material from inorganic material using sunlight.
Photo - light and synthesis - to make. So the word photosynthesis means to "make something using light".
In green plants, the mesophyll cells of the leaves contain a green pigment called chlorophyll. It is present in the grana of their chloroplast. The chloroplast is thus the site for photosynthesis.
The inorganic matter required for photosynthesis is obtained from the environment. The carbon dioxide is obtained from the atmosphere by the stomata and water is absorbed by the roots.
The chlorophyll traps the sunlight which provides the energy for the hydrolysis of water and the formation of glucose and oxygen as a byproduct.
Therefore, the molecules required for photosynthesis are carbon dioxide and water.

Reverse transcriptase is a useful enzyme to have when?
Answer:
Reverse Transcriptase (RT) is essential for HIV replication because the viral RNA genome on its own is highly susceptible to degradation by intracellular RNases. RT rapidly makes a much more nuclease-resistant double-stranded DNA copy of the RNA template that later integrates to form the proviral DNA.
This molecule is used by retroviruses to create DNA by using mRNA as a template. We know that normally transcription is the synthesis of mRNA from DNA. This can be useful in bioengeneering when using a virus as a vector to alter the genetic material of the host.
