Answers

1. It is important for gametes to be haploid because: B) They fuse to form a diploid organism so there is the correct number of chromosomes.

2. When the inheritance pattern of one gene doesn't affect the inheritance pattern of another gene, this is known as: D) independent assortment.

3.  A difference between phase I and phase II of meiosis is: B) Phase I results in two diploid daughter cells and phase II results in four haploid daughter cells.

4. Heredity simply refers to: B) the passing of genetic information from parents to their offspring.

5. During meiosis, sister chromatids may exchange sections of DNA leading to genetic diversity in a process called: D) crossing-over.

Gametes are also known to as sex cells and they can be defined as the reproductive cells that are found in a living organism.

It is important for gametes to be haploid cells is because when the sperm and the egg fuse to form a diploid organism, the living sex cells will have 46 chromosomes.

Independent assortment refers to a biological process through which the inheritance pattern of a particular gene doesn't affect the inheritance pattern of another gene.

During meiosis, two (2) diploid daughter cells are formed in phase I while four (4) haploid daughter cells are formed in phase II.

Heredity can be defined as the transfer of genetic information (traits) from the parents of a living organism to their offspring, either through sexual reproduction or asexual reproduction.

Some examples of hereditary traits are:

Dimples.Baldness.Height.

During meiosis, crossing-over makes it possible for sister chromatids to exchange sections of deoxyribonucleic acid (DNA) which leads to genetic diversity.

Explanation:

Natural reseeding uses natural elements and actors to plant the seeds of trees. These elements and actors include water, wind, birds, rodents and other actors capable of scattering seed.

Species diversity is what defines the differentiation between the different species in an ecosystem and Ecosystem diversity relates to how biological communities/ ecosystems can be different from each other based on the organisms and food chains available in each.

1- how does modern technology provide evidence that all organisms have a common ancestor?

2- what new discoveries about evolution have modern technology made possible?

Answers

Answer: 1. Homologous structures provide evidence for common ancestry, while analogous structures show that similar selective pressures can produce similar adaptations (beneficial features). Similarities and differences among biological molecules (e.g., in the DNA sequence of genes) can be used to determine species' relatedness.

2. The changes in our behavioral patterns and adaptations that are caused by these technological advances could prove to be the primary driving forces behind the next stage of evolution for our species. These members of the species are more likely to reproduce and pass their genes on to their children.

Explanation:

answer 1.from the claudography graph shows how the animals are related from a common ancestor
answer 2. the machines used to examine bones and even embryos

What is the difference between aggression and courtship?

Answers

Answer:

How you approach and talk to the person you like

Explanation:

If you go up and start saying inappropriate things or immediately try to kiss them then that is aggression. But if you go up and give them a subtle and light compliment like ''Hey I like your shirt" and start a conversation, maybe at the end ask (not demand)  for her number, then that is a courtship. P.S.If you say something like give me your phone number, that is aggression.

Some people call Earth the "Blue Planet," why do you think this is? Of all the water on Earth, only about 1% is available for human use. WHY?

Answers

Answer:

I think it's not because of the water we use it's the water we have.

Explanation:

Because our planet is made up of 75% water it is naturally the first thing to recognize.

Many people call Earth the “blue planet” because seen from far away, what really stands out of the planet, it’s the the ocean as the earth is most covered with water well salt water and most of the water is not available to humans because most of the water contains salt which is not fresh water, only a small percentage of the water is fresh and drinkable

A young goat has downward-curved horns. Its father has upward-curved horns while its mother has downward-
curved horns. Which of these statements explains why the young goat has downward-curved horns?

1. The young goat inherited one copy of the gene for horn shape from mother and one copy from its
father. That gene combination instructs for proteins that connect in ways that make downward-curved
horns.

2. The young goat inherited one copy of the gene for horn shape from its mother and one copy from its
father. Those genes connect together to make its downward-curved horns.

3. The young goat inherited its copies of the gene for horn shape from its mother and not from its father.
Just like its mother's genes, those genes instruct for proteins that connect in ways that make its
downward-curved horns.

4. The young goat inherited its copies of the gene for horn shape from its mother and not from its father.
Those genes connect together to make its downward-curved horns.
The young goat inherited its copies of the gene for horn shape from its mother and not from its father.
Those genes connect together to make its downward-curved horns.
