Answer:

chromosomal Mutation

Explanation: because the answer is B

The type of mutation will affect the largest number of proteins produced by an organism is Missense mutation. Thus, option D is correct.

In sickle cell anemia, a change in the DNA nucleotide sequence is observed, where adenine is substituted by thymine, whose expression is the change in the sequence of amino acids in β-globin, with valine being incorporated instead of glutamic acid. This constitutes a mutation of the missense type.

Missense mutations are characterized by the substitution of one nucleotide by another in the DNA sequence —a point mutation— whose consequence is reflected in the transcription and substitution of one amino acid by another in a protein, whose structure or function will be altered.

The change from glutamic acid to valine in β-globin causes an altered hemoglobin, giving the abnormal erythrocytes observed in sickle cell disease.

Therefore, the type of mutation will affect the largest number of proteins produced by an organism is Missense mutation. Thus, option D is correct.

Answer:

Explanation:

In eukaryotic cells, ribosomes are found in the cytosol of a cell, the mRNA , endoplasmic reticulum and also the matrix of the mitochondria. They are large molecules that catalyzes the synthesis of proteins, which is called translation. The ribosome choose tRNA and covalently links the amino acids into a polypeptide chain.

In prokaryotes, it can be found in cystosol and it help translate genetic code into protein.

B. eats more than just frogs

Explanation:

A food web is more realistic because a snake eats more than just frogs

A food web is more realistic because a snake eats more than just frogs. The correct option is B.

A food web is a network of interrelated food chains that represents the movement of materials and energy within an ecosystem. In a food chain, the various arrows symbolize the various species that are being consumed by one another and so represent the flow of energy. Additionally, it shows that an animal can eat a variety of foods.

Food chains that are linked together form food webs. In a food chain, arrows point from the organism being eaten to the organism eating it.

The energy flow in a food web is depicted by arrows. Food webs display every form of eating in an environment.

Thus, the correct option is B. eats more than just frogs.

Answer:

C) exponential growth​

In the given figure, exponential growth curve is pictured.

It is the pattern of data, which demonstrates greater enhancements with passing time, giving rise to a curve of an exponential function. During the growth cycle of bacteria, the cells of bacteria goes through different phases, that is:

In the case of bacteria, the cells enter the log or the exponential phase after the lag phase. This is the time when the cells get differentiate by the process of binary fission and double in numbers after each generation time.

In this pattern of growth, the metabolic activity is high as RNA, DNA, the components of the cell wall, and other substances essential for growth are generated for differentiation.

Thus, the pattern of growth demonstrated in the given figure is exponential growth.

Answer:

B. Digestion begins with enzymes in the stomach

Explanation:

The digestive process starts in your mouth when you chew. Your salivary glands make saliva, a digestive juice, which moistens food so it moves more easily through your esophagus into your stomach. Saliva also has an enzyme that begins to break down starches in your food.

In DNA base pairing, adenine always pairs with thymine, and guanine always pairs with cytosine. Adenine is also one of the bases in RNA. There it always pairs with uracil (U). The base pairs in RNA are therefore A-U and G-C.

Skeletal, Cardiac, and Smooth Muscle.

Explanation:

Skeletal Muscle:

The muscles attached to your bones that help pull and push when you move.

Cardiac Muscle:

Heart muscle that keeps the blood pumping. Is very thick and strong, as well as elastic to ensure smooth blood flow.

Smooth Muscle:

Essentially muscles in the other areas of your body, especially internal organs. For example, the muscles in your digestive system that involuntarily move food through your bowels are smooth muscles.

This is a basic picture on the three types! Hope that helped :)

Answer:

The best explanation was provided by the student Tara who said: "Through photosynthesis, the CO2 and water are changed into new substance, glucose, therefore it is considered a chemical change".

Explanation:

A chemical change is one which is not easily reversible and which results in the formation of new subsatances.

For example, in photosynthesis,a new substance, glucose is formed from the original substansubstances, carbon dioxide and water. Also, the reverse process of the formation of carbon dioxide and water from glucose is not easily obtained in plants.

From explanations provided by the students :

Luke does not give any explanation of the process but only an observation

Jackie's explanation does not state the main reason why a chemical change differs from a physical one.

Tara, gives the best explanation as the reason why a change that occcured is a chemical change is clearly stated.

Skyler does not state the main reason why photosynthesismis a chemical change as well, because even physical changes like evaporation of water involves solar energy.
