Answers
Answer:
The minimum number of nucleotides per codon necessary to specify all 20 amino acids that are found in proteins is 3
Explanation:
There are four nucleic acids in the RNA, adenine uracil, guanine, cytosine. Each of them combines in groups of three to give the different amino acids. In total, there are 64 different combinations of nucleic acids that codify the 20 amino acids that we need for our vital functions.

plssssssssssssssssssssssss a good paragraph with good vocabulary
Answers
A cell wall is a structural layer surrounding some types of cells, just outside the cell membrane. It can be tough, flexible, and sometimes rigid. It provides the cell with both structural support and protection, and also acts as a filtering mechanism.[1] Cell walls are present in most prokaryotes (except mollicute bacteria), in algae, fungi and eukaryotes including plants but are absent in animals. A major function is to act as pressure vessels, preventing over-expansion of the cell when water enters.

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.
Answers
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.

how does mangrove planting reduces impact of climate change
Answers
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.
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?
Answers
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.

A scientist is adding thermal energy to a sample of water. Using the Law of Conservation of Energy, what can you predict will happen? (3 points)
The water will increase in temperature beyond the amount of thermal energy that is added, because more energy will be created in this experiment.
The water will decrease in temperature as thermal energy is added, because it cannot create more energy or matter.
The water will not change its temperature because energy cannot be created or destroyed.
The water will increase in temperature in proportion to the amount of thermal energy that is added, but some will be lost to the environment.

Which of the following would represent the strand of DNA from which the mRNA

*
Answers
The option that would represent the strand of DNA from which the mRNA strand "CUCAAGUGCUUC" was made is "GAGTTCACGAAG."
What is DNA?DNA stands for Deoxyribonucleic acid. It may be defined as a type of molecule that is present inside cells that contains the genetic information responsible for the development and function of an organism.
It allows information to be passed from one generation to the next. Transcription is the process of copying a segment of DNA into RNA, especially in the form of mRNA.
It is the first step of protein synthesis through which complementary mRNA strands would be formed from DNA sequences. In this process, the adenine is replaced by thymine and vice-versa while guanine is replaced by cytosine and vice-versa.
Therefore, the option that would represent the strand of DNA from which the mRNA strand "CUCAAGUGCUUC" was made is "GAGTTCACGAAG."
