Because it's the muscle helps the body system with the skeletal system to enable voluntary movement of the organism

The answer for your question is B

Answer:

- DNA is wrapped around nucleosomes and condensed into chromosomes.

- Proteins affect the traits and function of organisms.

Explanation:

Nucleosomes are the basic unit of compaction of DNA. Each nucleosome is composed of ~148 bp double-stranded DNA and an octamer of histone proteins, which include two molecules of each core histone: H2A, H2B, H3 and H4. Subsequently, nucleosomes are packaged into chromatin fibers so they can be densely compacted into chromosomes. On the other hand, proteins are molecules that play important (structural and enzymatic) functions in a cell. These proteins may affect the structure/function of a cell, thereby affecting a certain characteristic/trait to develop.

Answer is in explanation

Explanation:

A silent mutation is a mutation in which a single nucleotide base is changed, but that change does not effect the amino acid sequence. A missense mutation is a point mutation in which a single nucleotide is changed, resulting in a codon that codes for a different amino acid.

The mutation is caused by the exchange of one base pair if no change in the overall protein (silence mutation),  if there is change in one amino acid (missense mutation).

A mutation is a difference in the DNA sequence of an organism.

Silent mutations happen when the difference of a single DNA nucleotide within a protein-coding portion of a gene does not influence the sequence of amino acids and the protein.

Thus, silent mutation has no change whereas stop mutation leads to termination of protein.

Answer:

these are odd questions....

Explanation:

1. they are curious about how they get blind

2. the quills

Answer:

1.The first hypothesis is that blindness gives the tetra some sort of evolutionary advantage. That advantage might be the result of pleiotropy, which is when multiple effects are caused by the same mutation in one gene. Scientists think that the mutation that causes blindness in the tetra might also cause a "seemingly unrelated change in the fish that is beneficial."

2. Another effect it might have is to improve cave tetras' sense of smell.

Answer: species whose habitat depends on mature trees in the top canopy layer will be excluded

Explanation:

The maximum sustainable yield refers to a biological resource maximum usable production which can be gotten at a particular period of time without the ability of the resource maintaining that particular production level reduced.

If forests are strictly managed according to this model, some biodiversity would still be lost due to the fact that species whose habitat depends on mature trees in the top canopy layer will be excluded.

Answer:

Part A: False

Part B: Liver enzymes may activate some innocuous compounds, making them mutagenic

Explanation:

The Ames test, also known as Salmonella typhimurium reverse mutation assay, is a bacterial short-term technique used to identify if a particular chemical compound may cause mutations in target cells. It has been shown that there exists a positive correlation between carcinogenicity and mutagenicity in the Ames test, but this correlation is not absolute. In the Ames test, a rat liver homogenate (containing liver enzymes) can be added in order to identify substances that are not mutagenic themselves but are metabolized in order to form a mutagen (e.g., benzopyrene).

Answer:

This is kinda confusing

Explanation:

Reproduction > Natural Selection > Adaptation/Evolution

Answer: In commensalism, one organism benefits, and the other neither benefits nor is harmed. In this case, plants benefited, and worms seemed neither to benefit nor be harmed.

Answer:

The answer is A.

Bacteria, which are prokaryotic cells are single-celled entities that are primitive in structure and function as they lack a membrane-bound nucleus and other organelles.

Eukaryotic cells are the cells that are complex in structure and function as they have a membrane-bound well-defined nucleus and other membrane-bound organelles.

Answer: The metamorphic rocks can erode into sedimentary rocks which can turn into igneous rock. Metamorphic rocks in the rock cycle is driven by tectonic plates.

Explanation:

Answer:

Genotype for AB: IA and IB

Genotype of for O: ii

Explanation:

Eukaryotic cells:

• There is a well defined nucleus

• They are membrane bounded cell organelles like chloroplast, golgi bodies, mitochondria.

Prokaryotic cells:

• The nucleus are not well defined

• Cell organelles are not bounded by membrane

Answer:

10 Units

Explanation:

If you makes an energy pyramid the energy from the plant to the organisms would be

plant (10,000) --> grasshopper (1000) --> frog (100) --> snake (10) --> eagle (1)

If 10,000 units of energy are available at the level of the plants, then one can estimate that the amount of energy available at the level of the frog is 1000, and then at the level of the snake it is 100 kJ, which is in option A.

The transfer of energy between trophic levels is known as energy flow, and in an ecosystem, the primary producers, such as plants, are at the first trophic level, followed by the primary consumers, such as herbivores like the frog, at the second trophic level. The secondary consumers, such as predators like the snake, occupy the third trophic level, as here the third one is the snake, and it will get 10% of the frog.

Answer:

C

Explanation:

The principle of superposition states that the oldest sedimentary rock units are at the bottom, and the youngest are at the top. Based on this, layer C is oldest, followed by B and A. So the full sequence of events is as follows: Layer C formed.

Answer:

The pond was warmer during the month of October.

Explanation:

Water has a high specific heat capacity, therefore more heat is required to change its temperature. This is why aquatic life is able to stay alive even when temperatures drop drastically. The sidewalk however, will more than likely adapt to the temperature change quickly as concrete does not have a very high specific heat capacity.

Answer:

Answer:

The answer is A

Explanation:

Let us take a look at the owl, it is a kind of carnivore, so it must be a secondary consumer(btw, primary consumers are herbivores). So we can eliminate answer C and D. The competition between the same species for this situation is the most intense one, so we can eliminate answer B as well, since hawk and owl are all birds. So the answer is A.
