Answer:
C I think
Explanation:
Cell A shows active transport and Cell B shows diffusion in the given diagram.
What are the types of transport methods?
All higher organisms, including humans, animals, and plants, go through a process called transportation that is necessary, natural, and part of their physiological makeup. To support life, this interaction is significant as it capabilities by continually shipping, different fundamental materials to and from all pieces of the body including cells, tissues, and organs.Water, hormones, gases, mineral nutrition, organic material, and other things are the primary essential materials. An organism's various modes of transportation include:Active transport Passive transport Facilitated transportDiffusion.The term "active transport" refers to a process in which molecules use external energy to move from a lower concentration area to a higher concentration area against a gradient or obstacle.Any substance's overall movement from a higher concentration area to a lower concentration area is known as diffusion. This can occur between cells or within them. Due to the random movement of their particles, only gases and liquids experience diffusion. It is an essential biological process. It is how things enter and exit cells. It occurs naturally and does not call for any energy.The container or the particles themselves come into contact with one another. In the end, the particles cover the entire container. There is no stirring, shaking, or wafting during diffusion.We refer to this as the concentration gradient down because diffusion is the movement of particles from a higher concentration to a lower concentration.

Suppose you mate a black rooster with a white hen. The feathers of all the offspring are “gray,” a color that is intermediate between black and white. Explain the inheritance pattern in these chickens.
Answers
Answer:
Incomplete dominance
Explanation:
The inheritance pattern described here is called incomplete dominance (sometimes also referred to as semi-dominance or partial dominance). This occurs when the dominant allele doesn't fully prevent the effects of the recessive allele from being expressed. This results in the trait of the offspring being equivalent to the mix of both alleles. If the rooster's feathers are black and the hen's are white, the chicks' will be grey.

Why is the dysphotic zone around coral reefs shallower than the dysphotic zone in the open ocean?
There is more oxygen in the open ocean.
The sun is brighter over the open ocean.
There is more nitrogen by the coral reefs.
There is more plankton by coral reefs.
Answers
Answer: There is more plankton by coral reefs.
Explanation: Plankton tend to hang around surface waters which coral reefs also grow in. And most of that Plankton are plants that need more sunlight. So the sun would be brighter in shallower waters rather than open ocean.

How does biodiversity reduce one species’ dependence on another species? Explain, and provide an example.
Answers
Answer:
For example, two animal predators may consume different prey items, so they are less likely to compete with one another, allowing higher total biomass of predators in the system. In the case of plants, all species may utilize the same suite of resources (space, light, water, soil nutrients, etc.)
Explanation:
The presence of large biodiversity can reduce one species dependence on another species as it provides resources such as food which will reduce the chances of a species to become threatened.
What is biodiversity?Biodiversity can be defined as the variety of all the different kinds of organisms such as the plants, animals, insects and microorganisms which live on the planet.
A large biodiversity is helpful for the species as it increases the stability of the ecosystems. This is possible because it reduces the dependence of one species on another, for the instance for food. For example, if a species has only one food source, it may be easily threatened by the environmental changes. However, if many species similar to it are present in the ecosystem then the chances of the species to become threatened are very low.

Sperm cells of a specific species of mice have 16 chromosomes. What is the expected number of chromosomes in an adult mouse of this species?
Answers
Answer:
32 chromosomes (16 pair)
Explanation:
Gametes or sex cells of sexually reproducing organisms are produced via a process called MEIOSIS, which is a type of cell division that reduces the chromosomal number of the parent cell by half. Hence, a mice that produces a sperm cell (gametes) via meiosis with 16 chromosomes will have double that amount in somatic cells of that mouse.
That is, the expected number of chromosomes in an adult mouse of this species with 16 chromosome in its sperm cell is 32 since half of this number makes up the chromosomal number in gametes

A process that increases genetic diversity during meiosis
Answers
Answer:
During the prophase of meiosis I, the double-chromatid homologous pairs of chromosomes cross over with each other and often exchange chromosome segments. This recombination creates genetic diversity by allowing genes from each parent to intermix, resulting in chromosomes with a different genetic complement.
Explanation:
Through a process known as crossing over, which enables new combinations of variants to appear in the gene pool, meiosis promotes genetic diversity.
What is meiosis?During the prophase of meiosis I, homozygous chromosomes are next to one another and exchange genetic material.
There could be a heterozygous state for a gene if two distinct alleles are present on the same genetic locus on homologous chromosomes. (For instance, an allele for antigen A on one chromosome and an allele for antigen B on another; both are used to determine the ABO blood group.)
Numerous genes are linearly ordered on chromosomes; as a result, some of them may still be heterozygous. (The same person may be heterozygous for the ABO blood group, iris color, and sickle cell anemia).
Therefore, Through a process known as crossing over, which enables new combinations of variants to appear in the gene pool, meiosis promotes genetic diversity.

Answers
Answer:

Explanation:
Plants get the carbon from the air which are needed to make the glucose molecules during the process of photosynthesis in plants. Thus, the correct option is B.
What is Photosynthesis?Photosynthesis is the process of formation of carbohydrate (sugar) in the green leaves of plants. This process takes place in the presence of light. In this process, the light energy (solar radiation) is trapped in the chlorophyll pigment present in the green leaves of plants, this energy is converted into chemical energy in the form of glucose (carbohydrate) which is used by the plants in various processes.
The reaction includes the reaction between carbon dioxide and water molecules which are present in the air to produce glucose and oxygen gas which are consumed as food and in the process of respiration.
Therefore, the correct option is B.
