2. Early life helped make the oceans livable for oxygen-dependent species.

The electron transport chain (ETC) is the final step of cellular respiration and takes place in the mitochondrion.

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.

Answer:

An earthquake is what happens when two blocks of the earth suddenly slip past one another. The surface where they slip is called the fault or fault plane. The location below the earth’s surface where the earthquake starts is called the hypocenter, and the location directly above it on the surface of the earth is called the epicenter.

Sometimes an earthquake has foreshocks. These are smaller earthquakes that happen in the same place as the larger earthquake that follows. Scientists can’t tell that an earthquake is a foreshock until the larger earthquake happens. The largest, main earthquake is called the mainshock. Mainshocks always have aftershocks that follow. These are smaller earthquakes that occur afterwards in the same place as the mainshock. Depending on the size of the mainshock, aftershocks can continue for weeks, months, and even years after the mainshock!

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.

Answer:

prokaryotes and eukaryotes I believe

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.

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.

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.

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.

The statement that best describes symbiotic relationships is different species live in close associations in an ecosystem. The correct option is A.

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.
