Answer:

You have a trait (plant color) and you have two possible outcomes for it (purple and white). You know that some alleles for white were present in one of the parent plants, so you know they must be present in the offspring too. But they're expression is covered up by the purple alleles from the other plant, so you know that purple is dominant to white.

c:

Variety in offspring due to random DNA mixing promotes adaptation, survival, and species diversity, essential for evolutionary progress.

Sexual reproduction creates variety in offspring through the random mixing of parents' DNA, known as genetic recombination.

This genetic diversity is a crucial part of evolution as it enables species to adapt to changing environments, allowing for better survival prospects.

Diverse traits within a population increase the chances of some individuals possessing advantageous characteristics that promote reproductive success.

Over time, these traits become more common, leading to evolution. Without this genetic variation, a species would struggle to adapt and could face extinction.

Therefore, sexual reproduction and the resulting variety are vital for species survival and evolutionary development.

The activity of pepsin would gradually decreases when it is exposed to higher pH in the small intestine. This is because in higher pH the enzyme pepsin denatures.

The role of Pepsin in the stomach is determined by the fact that it serves to digest proteins found in ingested food. The Gastric chief cells typically secrete pepsin as an inactive zymogen called pepsinogen.

Parietal cells within the stomach lining effectively secrete hydrochloric acid that ultimately decreases the pH of the stomach. A low pH (1.5 to 2) activates pepsin.

It is thought that the role of pepsin is better played in the pH lies between 1.5-2. But when pepsin enters the region of the small intestine, the pH gradually increases and reaches 8. At this, the activity of pepsin is inhibited due to its denaturation.

Therefore, the activity of pepsin would gradually decrease when it is exposed to higher pH in the small intestine. This is because in higher pH the enzyme pepsin denatures.

DNA carries the blue print while it is transferred to the genes by the RNA

In protein synthesis, DNA serves as a blueprint for creating messenger RNA (mRNA), which then carries the genetic information from the nucleus to the ribosome where it is translated into a specific protein. The mRNA codons, or sequences of three nitrogenous bases, are read by ribosomal RNA (rRNA) and matched with complementary transfer RNA (tRNA) molecules carrying specific amino acids.

The ribosome uses the information in the mRNA codons and the amino acids carried by tRNA to build a linear chain of amino acids, forming a protein.

I'm pretty sure the Sun is the main source of energy.

Explanation:

Here is what I found:

Energy from the sun is the primary source of energy for the earth's ecosystem. The sun's energy is collected and processed by plants through photosynthesis and converted into food for animals. Without the sun, animals would not exist. Food is stored energy and essential elements like carbon, nitrogen and hydrogen.

The main source of energy for both plants and animals is glucose. Therefore, the correct option is option C.

The process of photosynthesis, which plants use to transform solar light energy into chemical energy, makes plants one of a kind. Here, plants use the energy from sunlight to change water and carbon dioxide into glucose, a simple sugar, and oxygen. Plants require glucose as a vital source of chemical energy in order to grow, reproduce, and perform other metabolic functions. The majority of life on Earth gets its energy mostly from this conversion of solar energy into chemical energy. On the other hand, sunlight cannot be used by animals as a direct source of energy. They instead rely on eating plants or other animals to meet their energy needs.

The type of membrane protein that is affected in cystic fibrosis is a chloride ion channel.

Cystic fibrosis is an inherited condition in which the mucus in the body becomes thick and sticky. It can cause breathing difficulties and frequent infections, among other symptoms. Because the mucus is thicker than normal, it can obstruct the ducts of the pancreas, preventing digestive enzymes from reaching the small intestine.Cystic fibrosis is an autosomal recessive genetic disorder.

This means that in order to inherit the disease, a person must inherit two copies of the mutated gene, one from each parent.

Cystic fibrosis is caused by a mutation in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The CFTR gene provides instructions for making a protein called the cystic fibrosis transmembrane conductance regulator. This protein functions as a chloride ion channel, which helps regulate the flow of salt and fluids in and out of cells.

However, in people with cystic fibrosis, the CFTR protein is either missing or not functioning properly due to a genetic mutation. As a result, the salt and water balance is disrupted, leading to the production of thick, sticky mucus that clogs the airways, digestive tract, and other ducts in the body.

The cells of plants and animals are structurally different from single-celled eukaryotes in several ways. Plants and animal cells have a more complex structure and a higher degree of organization than single-celled eukaryotes. Plant and animal cells have a nucleus, cytoplasm, endoplasmic reticulum, Golgi apparatus, mitochondria, and other organelles, whereas single-celled eukaryotes usually only have a nucleus, cytoplasm, and some organelles.

Multicellular organisms like animals and plants have specialized cells to perform different functions. The cells in animals and plants are different from single-celled eukaryotes in terms of structure. Animals and plants have membrane-bound organelles that are absent in single-celled eukaryotes.

There are structural differences between the cells of plants and animals, as well as single-celled eukaryotes. The structural differences between them are as follows: Plant cells have a rigid cell wall composed of cellulose. A cell wall is absent in single-celled eukaryotes and animal cells. Plant cells have a large central vacuole that stores water and other substances.

Single-celled eukaryotes have small vacuoles, and animal cells may have small vacuoles or none. Plant cells have plastids, which are membrane-bound organelles. Single-celled eukaryotes and animal cells do not have plastids. Chloroplasts are a type of plastid that performs photosynthesis, which is the process by which plants make their own food. Chloroplasts are not present in single-celled eukaryotes or animal cells.

Animal cells lack a cell wall but have a plasma membrane that regulates the movement of substances into and out of the cell. The plasma membrane is present in single-celled eukaryotes and plant cells. Animal cells lack chloroplasts, plastids, and a large central vacuole. Instead, they have small vacuoles that store various substances.

Animal cells have lysosomes, which are membrane-bound organelles that contain enzymes to digest and recycle waste materials. Lysosomes are not present in plant cells or single-celled eukaryotes. In single-celled eukaryotes, Single-celled eukaryotes have a single-cell membrane that encloses the entire cell.

Unlike plant cells and animal cells, single-celled eukaryotes lack specialized organelles such as mitochondria, ribosomes, and a nucleus. Single-celled eukaryotes are diverse in form and function. Some are autotrophs, which can synthesize their own food, while others are heterotrophs, which require a ready-made source of nutrients.

The following are characteristic of an individual lacking an intrinsic factor are b. the person will have vitamin B12 deficiency, c. likely be diagnosed with pernicious anemia, and f. appearance of large pale cells called macrocytes in their blood stream

This is because the intrinsic factor is a glycoprotein that is produced by the parietal cells of the stomach and is necessary for the absorption of vitamin B12 in the small intestine. Without the intrinsic factor, vitamin B12 cannot be absorbed, leading to a deficiency. Pernicious anemia is a type of anemia that is caused by the inability to absorb vitamin B12 due to the lack of intrinsic factor.

Aplastic anemia (d) is a condition where the bone marrow does not produce enough new blood cells, and it is not typically associated with a lack of intrinsic factor. The appearance of large pale cells called microcytes (a) is a characteristic of iron deficiency anemia, which is not related to a lack of intrinsic factor.
