Answer:
Genetic Separation / Geographic isolation
Explanation:
Morphological distinction (or phenotypic differentiation) can be defined as the diversification of a set of observable physical characteristics in a population, capable of differentiating certain species.
The genetic separation occurs when the division of a group of genes into two or more pools of genes separated over time and depending on several other situational factors.
Geographic isolation occurs due to the physical separation of subpopulations of a given species. The barriers that isolate these subpopulations can be, for example, a river that cuts through a plain, a valley that divides plateaus or a portion of the sea that separates islands and continents.

What is Electron Transport Chain and what happens in that stage of cellular respiration?
The electron transport chain (ETC) is the final step of cellular respiration and takes place in the mitochondrion.
The final step in cellular respiration is the electron transport chain. This is sometimes abbreviated as ETC. ETC needs oxygen, which means aerobic process. It occurs at the edges of the inner lining of mitochondria. These handles are called cristae.

Meiosis I is often referred to as reduction division because it results in the reduction of the chromosome number from diploid to haploid. The chromosomes that remain in each cell are made of sister chromatids. During meiosis II, what will happen to the sister chromatids?
Answer: they will separate into different cells.
Explanation:
They separate into 4 cells.
Sister chromatids separate during meiosis II, resulting in haploid cells with non-duplicated chromosomes.
What is sister chromatid?A sister chromatid is two identical copies of a chromosome formed by DNA replication, with both copies joined together by a common centromere.
To put it another way, a sister chromatid is 'one-half' of a duplicated chromosome. A dyad is a pair of sister chromatids.
Meiosis II is analogous to mitosis. There is, however, no "S" phase. Because of recombination, the chromatids of each chromosome are no longer identical.
Meiosis II separates the chromatids, resulting in two daughter cells with 23 chromosomes (haploid), each with only one chromatid.
Thus, during meiosis II, there will be the separation of the sister chromatids.

the way that genetic information is coded in DNA is-
Answer:
with bases
Explanation:
Genetic information is coded in DNA by means of four bases: two purines (adenine and guanine) and two pyrimidines (thymine and cystosine). Each adjacent sequence of three bases (a codon) determines the insertion of a specific amino acid. In RNA, uracil replaces thymine.

how does mangrove planting reduces impact of climate change
Answer:
By slowing down the movement of water and catching sediment, mangroves help reduce the impacts of storm waves and flooding. mangroves also prevent greenhouse gasses which helps climate change.
Explanation:
Answer:
Besides protecting shorelines from extreme weather and providing fish a safe place to breed, mangroves could play a big role in trapping climate-changing carbon emissions, something that has so far been largely overlooked, they said. As mangroves are cleared at a rate three to five times faster than other forests, according to UNEP estimates, those losses are particularly felt in developing countries where most mangroves are located, including Bangladesh, India, Pakistan, Sri Lanka, Kenya, Senegal, West Bengal, Vietnam and Sumatra. Like other plants, mangroves take carbon dioxide from the air as they photosynthesize. They use this carbon dioxide to produce more leaves. As a result, this carbon gets locked in the leaves instead of the air. This is why plant communities like forests and grasslands are called “carbon sinks". As leaves fall from trees, they decompose and the trapped carbon slowly drains back into the atmosphere. Mangrove leaves drop into the water. Lower oxygen levels in that water means that leaves decay more slowly than they would in air. The leaves also serve as a primary food source for a variety of animals like worms, shrimp, fish and crabs. These animals transport that carbon to deeper water. Deeper still if they are eaten by larger animals. When they die, they sink to the bottom where their carbon remains trapped indefinitely.

Observation of Diffusion Rate in Relation to Cell Size
As you have observed, cells are small. Consider your little toe: it is made of about 2-3 billion
cells! A newly-made cell will grow, but once it reaches a certain size it will divide to form two
new cells rather than growing bigger. Why is this? Why aren't you made of a few dozen, or a
few hundred cells, instead of trillions? Why don't single-celled organisms like amoebas and paramecia grow
as big as a human? In this lab, we will investigate this question using model cells.
Explanation:
new cells rather than growing bigger. Why is this ?
There are two main reasons why cells divide rather than continuing to grow larger and larger: ... If the cell grows too large, it will have trouble moving enough nutrients and wastes across the cell membrane. Cell Division. Cell division is the process by which cellular material is divided between two new daughter cells.
Why aren't you made of a few dozen, or a
few hundred cells, instead of trillions?
if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume. When this happens, the cell must divide into smaller cells with favorable surface area/volume ratios, or cease to function. That is why cells are so small.
Why don't single-celled organisms like amoebas and paramecia grow
as big as a human? again The important point is that the surface area to the volume ratio gets smaller as the cell gets larger. Thus, if the cell grows beyond a certain limit, not enough material will be able to cross the membrane fast enough to accommodate the increased cellular volume.

What statement best describes symbiotic relationships?
O Different species live in close associations in an ecosystem.
Abiotic factors interact in an ecosystem.
O Saprophytes respond to abiotic changes in an ecosystem.
O Ecosystem feeding levels show changes in energy.
The statement that best describes symbiotic relationships is different species live in close associations in an ecosystem. The correct option is A.
What is the symbiotic relationship?Symbiotic relationships are those relationships in which two organisms live together and depend on each other for nutrition and space. In symbiosis, both organisms help each other.
For example, cattle and egret. The egret is a wading bird that feeds on the ticks or lice of the cattle. Eating them through the body helps clean the body of the cattle, and it also provides nutrition to the egret.
In an ecosystem, different organism lives together. Tress provides space and food for the animals. Animals help in the dispersion of seeds of various plants. In short, it is symbiosis.
Thus, the correct option is A. Different species live in close associations in an ecosystem.

Keratin serves important structural and protective functions, particularly in the epithelium. Some keratins have also been found to regulate key cellular activities, such as cell growth and protein synthesis
When the water availability of a plant's environment decreases, the plant can respond by closing its stomata. This reduces the amount of water that the plant loses through its leaves due to transpiration. Closing the stomata also reduces the amount of carbon dioxide that the plant can take in through its leaves, which will most likely result in A. a decreased rate of photosynthesis. B. no change in the cellular processes of the plant. C. an increased rate of photosynthesis. D. an increased rate of cellular respiration.
Answer:
A. a decreased rate of photosynthesis.
Explanation:
Stomata is a structure in the leaves of higher plants, which they use majorly for the purpose of gas exchange. However, the process whereby plant loses water called transpiration also occurs via the stomata. In a situation whereby the availability of water in a plant's environment is low, the plant responds by closing its stomata in order to conserve water (reduce the amount of water that the plant loses through its leaves due to transpiration).
Closing the stomata by plants means not allowing ample carbon dioxide (CO2), which is needed for the process of photosynthesis to occur, to enter the plant. This will most likely result in a DECREASED RATE OF PHOTOSYNTHESIS.
