Differences: They are different in the manner that they cycle. Nitrogen gas is quite abundant (78% of the air around us is nitrogen). It cannot be used by plants or animals in its gaseous form though. ... Carbon, on the other hand, requires no special processing by bacteria prior to plants and animals being able to use it.

The carbon reservoir that has the longest residence time is known as a fossil deposit. Thus, the correct option for this question is D.

A carbon reservoir may be defined as being stored form of carbon in rocks and sediments. The rest is located in the ocean, atmosphere, and in living organisms. These are the reservoirs through which carbon cycles.

The movements of carbon take place through the four major reservoirs of the earth. It includes the biosphere, lithosphere, hydrosphere, and atmosphere. Plant biomass holds carbon for a very less period of time followed by soil. But the deposits of fossils hold the concentration of carbon for a maximum period of time.

Therefore, the carbon reservoir that has the longest residence time is known as a fossil deposit. Thus, the correct option for this question is D.

Answer:

Plants, like all living things, need food to survive. Plants make their food using a process called photosynthesis, which means “putting together through light.” During photosynthesis, a plant traps energy from sunlight with its leaves. It also takes up water from its roots and carbon dioxide gas from the air.

Answer:

Hypotonic

Explanation:

When you are comparing solutions with unequal solute concentrations, the solution with a higher solute concentration is a hypertonic, while the one with a lower one is a hypotonic. If they are equal, then they are isotonic.

Answer: B

Explanation:

To help the pioneer species to grow, it needs to have rapid reproduction. But, it also needs the sun to grow very well. If it does not have the Sun, it will most certainly die and be endangered in the area. The answer is B, we need both rapid reproduction and the Sun.

Answer:

rapid reproduction and the ability to grow in sunny places

Explanation:

After a major fire, less sunlight is blocked by trees and other plants. Plants that can use the increased sunlight are more likely to thrive in the new environment. Rapid reproduction would help a plant species to spread more quickly to take advantage of the resources and lack of competition. Therefore, the adaptations that would help grass be a successful pioneer species are rapid reproduction and the ability to grow in sunny places.

Explanation:

The evolutionary significance  of the switch from asexual to sexual mode of reproduction in some species under unfavorable environmental conditions is because of the need of More mutations and variations can be made in the species. The asexual mode causes the making the same copy so when there needs to be change.

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.

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.

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.

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.

The daughter cells have the same number of chromosomes and the same amount of DNA.

Explanation:

Mitosis is a process where the nucleus divides, so at first we have 46, and we need to bring it down to 23, because that is how much our cells can take, but after mitosis, the daughter cell will end up with 2 new cells, and it will have 23 chromosomes in each of the cells.
