SSomoene help plssssssssssss

Answer:

I'm not quite sure what your looking for

Explanation: scientists can take the genes of one successful crop, animal, etc, and insert that gene into future things so all offspring will be successful. This is called genetically modifying. Another thing scientists can utilize genes for is cloning. There have been ideals of the perfect human for many years and now scientists are trying to alter these genes to have perfect offspring according to your standards.

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:

- 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:

the population of penguins and krill will go up

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:

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.

Hope this will help❤️

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:

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.

Explanation:

i said so

The answer is series circuit.

Answer:

O

Explanation:

It would be type O, because both parents have type O. Whether it was positive (+) or negative (-) would depend on both parents.

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.

Explanation:

Answer: A moon has less mass than a star and more mass than the planet it orbits. A planet has less mass than a galaxy and more mass than the star it orbits. A galaxy has less mass than a moon and more mass than a planet. A star has less mass than a galaxy and more mass than a planet.

Answer:insulin and glucose

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:

B

Explanation:

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

Answer:

Its a male, without down syndrome

Explanation:

The fact that it's a male is indicated from the presence of the Y chromosome. In order for this man to have down syndrome, he would have had 3 chromosomes at 21, which he doesnt, meaning he doesnt have down.

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:

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:

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).
