The possible allele combinations from the gametes of an organism with the genotype of AaBb is AB, Ab, aB, and ab. The correct option is D.

What are alleles?

Alleles are variations of the gene. The offspring contain genes or traits from both parents. The same trait is given by both parents, one become dominant and one become recessive.

A gamete is a haploid cell that fuses with another cell to produce offspring, This occurs during fertilization. The female gamete is called ova or egg, or male cells are sperms.

When the genotype that will be produced by the fusion of AaBb is AB, Ab, aB, and ab. The small letters denote the recessive gene and the capital letter denotes the dominant genes.

Thus, the correct option is D. AB, Ab, aB, and ab.

In Gregor Mendel's study with the color or peas, which ones were dominant and which ones were recessive?

Answers

Answer:

The peas with the purple flowers were dominant and the peas with the white flowers were recessive.  

Explanation:

In Gregor Mendel's study, he studied pea plants with purple flowers and white flowers.  The purple flowers were dominant, and whenever the allele for a purple flower was present is was visible on the plant.  The white flowers were recessive because if an allele for a purple flower was present, then the flower was purple.  The flowers were only white if both alleles were for white flowers.

Answers

Answer:

true

Explanation:

i took the test

The statement "Newton's third law of motion states that whenever a first object exerts a force on a second object. The first object experiences a force equal in magnitude but opposite in direction to the force that it exerts" is true.

What is Newton's third law?

His third law argues that there is an equal and opposite reaction to every action (force) in nature. When object A pulls on item B, object B pulls back on object A with an equal and opposing force. In other words, interactions lead to forces.

According to the first law, until a force acts on an item, it will not alter its motion. According to the second law, an object's force is determined by multiplying its mass by its acceleration. According to the third law, when two objects interact, they exert equal-sized and opposite-direction pressures upon one another.

Therefore, the statement is true.

How could plants living in an industrial area be affected by smog?

Answers

Answer: The ground level ozone present in the smog also inhibits plant growth and causes immense damage to crops and forests. ... The smog results in mortifying impacts on the environment by killing innumerable animal species and green life as these take time to adapt to breathing and surviving in such toxic environments.

Explanation:

A type of air pollution in which the fog and smoke get mixed in the atmospheric air is called smog. It causes opacity and odour in the environment.

Smog is released from the factory that contains carbon dioxide, sulfur dioxide and smoke from the outlets.

Smog blocks the sunlight and the chemical released goes into the root system of plants interfering with the plant metabolic processes.

This causes damages to the leaves of plants and inhibits the plant process.

Therefore, smog from industries kills the plant.

Explanation:

cytokensis is the physical process of cell division. It divides the cytoplasm of a parental cell into two different daughter cells.

In plants, a cell wall forms. Cytokensis occurs in mitosis and meiosis. The objective for cytokensis is to divide the parent cell into two daughter cells. So cytokensis in plants is when a cell wall forms in between the daughter cells. Plant cells have walls, so they CANNOT divide using a cleavage furrow. A cell plate forms across the cell during telophase.

In animal cells, cleavage furrow forms. This pinches the cell in half and forms two different cells.
