4 genetically different haploid cells

Explanation:

meiosis gives rise to four unique daughter cells, each of which has half the number of chromosomes as the parent cell.

4 genetically different haploid cells.

What is Meiosis?

In sexually reproducing organisms, meiosis is a kind of cell division that results in a reduction in the number of chromosomes in gametes (the sex cells, or egg and sperm). Body (or somatic) cells in humans are diploid, meaning they have two sets of chromosomes (one from each parent).

The egg and sperm that combine during fertilization must be haploid, or having only one pair of chromosomes, in order to sustain this state. Each diploid cell divides twice during meiosis to produce four haploid daughter cells, which are the gametes.

Nearly every human cell contains 46 chromosomes, 23 of which come from one of our parents and 23 highly similar chromosomes from the other parent.

Therefore, 4 genetically different haploid cells.

Mistletoe is a green plant that can make its own food, but also derives food from the mesquite tree on which it lives. In this way mistletoe is able to steal water and valuable minerals from the tree. 1. What is the advantage and disadvantage of this relationship to each organism? 2. What would happen to the mistletoe population if mesquite trees increase in number? 3. What type of symbiosis is this?

Answers

Answer:

1. Mistletoe is parasitic to the mesquite tree, it steals from the tree without giving anything valuable back to it. In this case, only the mistletoe gains an advantage.

2. If the mistletoe population on the tree were to increase, the mistletoe would probably end up slowly killing the tree. I say this because its a parasite to the tree. Its constantly stealing water and valuable minerals that it needs and doesnt give back anything that could help the tree. With all the water and minerals being stolen and an uneven rate with no way for the tree to replenish it all quickly enough it'll die.

3. Its parasitic since the mistletoe just takes and takes harmfully

A) Habitat restoration
B) Urbanization
C) Terrace farming
D) Reforestation

Answers

Answer:

b

Explanation:

Urbanization is one way people have negatively affected land resources. Therefore, the correct option is B.

What is Urbanization?

The process of urbanization occurs when the percentage of a country's population living in urban areas increases. This is a result of rural-urban migration, which occurs when people move from rural to urban areas in search of better job prospects, social services, and living standards. Urbanization has both beneficial and harmful effects on the environment and society.

On the plus side, urbanization can promote economic growth, better infrastructure, and greater access to social services, including healthcare, education, and social assistance. Additionally, it helps reduce stress on rural communities, which may experience issues of resource scarcity, resource overabundance, and environmental degradation.

Therefore, the correct option is B.

Donald is trying to get through a door but his friend Goofy is blocking the way using 15 N of force. Donald finally pushes on the door with 20 N and gets through knocking Goofy out of the way. Solve for net force.

Answers

Answer:

5 N

Explanation:

Goofy is blocking the way with 15 N force and Donald was only able to knock Goofy off using a 20 N force. The net force would be the difference between the applied force of Donald and that of Goofy.

Hence,

      20 N - 15 N = 5 N

The net force is, therefore, 5 N.

A segment of DNA is represented in the illustration.

Answers

Answer:

DNA is made up of molecules called nucleotides. Each nucleotide contains a phosphate group, a sugar group and a nitrogen base. The four types of nitrogen bases are adenine (A), thymine (T), guanine (G) and cytosine (C). The order of these bases is what determines DNA's instructions, or genetic code

Explanation:

As a sequence of nucleotides it is the information for a specific protein carried on the DNA molecule. The correct option is A.

What is nucleotide sequence?

The most fundamental understanding of a gene or genome is its nucleotide sequence.

Without having this information, no understanding of how genes function or how evolution works would be complete. It is the blueprint that carries the instructions for developing an organism.

The four nucleotides that make up DNA are adenine (A), thymine (T), guanine (G), and cytosine (C) (C).

The two DNA strands are connected by base pairs, which are formed when the nucleotides (A with T and G with C) bind to one another.

It is the data for a particular protein contained on the DNA molecule as a sequence of nucleotides.

Thus, the correct option is A.
