Heredity and Reproduction

Answers

Answer:

D and E

Explanation:

Because two parents are involved, the rate of reproduction is lower in sexual reproduction, but it is beneficial to have increased genetic diversity in the offspring since the level of adaptations in phenotypes will be higher.

The statements which accurately support the argument that procreation  is advantageous over propagation in many species are given below:

Procreation involves two parents which contribute equally to the offspring's genetics.Procreation involves meiosis and fertilization which leads to increased genetic variation in the offspring.

What do you mean by Species?

Species may be defined as a group of organisms that can reproduce naturally with one another and create fertile offspring.

Due to the involvement of two parents, procreation increases the genetic diversity among organisms.

In procreation, clutch size is low but parental care is high. It means that this type of reproduction does not produce a large number of offspring.

Therefore, it is well described above.

What structures do all organisms have in common in the earliest stages of embryonic development

Answers

The early stages of embryonic development begin with fertilization. The process of fertilization is tightly controlled to ensure that only one sperm fuses with one egg. After fertilization, the zygote undergoes cleavage to form the blastula.

The formation of a zygote after fertilization and undifferentiated cell are common features during the earliest stages of embryo development.

In vertebrates, fertilization is the process by which two geminal cells fuse to form a zygote, which will develop into an adult organism.

The cells are all in an undifferentiated state during the earliest stages of embryonic development.

After this process, the cells begin to differentiate to form a defined structure known as gastrula.

In conclusion, the formation of a zygote after fertilization and undifferentiated cell are common features during the earliest stages of embryo development.

Answers

Answer:

False

Explanation:

The eye spot instead creates a disguise and used to misdirect predators. The eyespots are a defense mechanism for the organism. Scientists have tested this by painting eye spots on a gake prey and a fish was used a s the predator. The predator was discovered to have attacked the fake eyespots more often as it thought it was the prey's head.

Eyespots on a prey can also make the predator to think that it is facing a larger animal. An example is the butterfly which have large false eyes on its wings.

PLS HELP ASAP DUE SOON PLS AND THANK U ILYSM IF U DO HELP.

Answers

Answer:

1. Yes and No. Speaking from the POV in which penguins are better of packed together than spread out since they are all focused on a specific region which is the southern hemisphere at the south pole I don't think spreading them out even when having the same exact species would help them survive since they need one another, but speaking in a different POV where multiple species are put in every cold region then yes it may work and it may also benefit in science fields to help ease the search of species and studies of them as well as the habitat of penguins themselves.

2. Penguins share many adaptations because of the idea of them only living in a cold, freezing region. Like, they spent half their time in water and the other half on land. Added to that, all penguins swim very fast due to webbed legs which helps them in surviving in a 100% water environment since Ice is technically frozen water. And they share many more adaptations all because of the cold region habitat they all share.

( I didn't really understand the 3rd one but Ill give it my own opinion )

3. Different geographical locations as I mentioned in the first question also speaks of how penguins wouldn't really survive much without being with their own species or their own type of penguins if that makes sense, although they are predators sometimes the environment might not give them the needed resources like food, warmth, strong legs to swim. Some baby penguins might grow up weak which would lead to weak physical structure which decreases the rate of survival because of not eating well nor keeping a healthy penguin routine that they usually do on the populated area of penguins in the southern hemisphere. So, weak physical structure leads to penguins not having their capabilities of being the predator in the environment and swimming as fast as others. Different environments and geographical locations may have an effect on this depending on penguin species but that's all I know.

I hope this helped :) .

Explanation:

Children inherit half of their genes from parents. Explain Why?

Answers

Answer:

This is because the two parents share one or more common ancestors and so carry some of the same genetic material. If both partners carry the same inherited gene change, their children are more likely to have a genetic condition.

Answer:

yes

Explanation:

The chromosomes in cells line up in pairs and exchange bits of genetic material before forming an egg or sperm cell. Each mature egg and sperm then has its own specific combination of genes, which means children will inherit a slightly different set of DNA from each parent.

Mistakes in making copies of a cell's chromosomes can occur as the cell is dividing. Such mistakes can affect a single gene, or a portion of a chromosome. Which term describes this process?​

Answers

Answer:

Mutation

Explanation:

A mutation is any change in the nucleotide sequence of the genome of a particular organism. Mutations may be caused by errors during DNA replication or by exposure to environmental mutagenic factors (e.g., ultraviolet radiation, chemical agents, etc). Mutations can be deleterious, neutral or beneficial depending on the environment. When a beneficial mutation occurs in the germline, it may potentially be inherited and subsequently increase its frequency in the population.

Answers

Answer: B,C

Explanation:

I did just did the USA test prep

The outcomes of meiosis and the potential gamete combinations  that could form from the genotype for an individual who is AaBbCcDd:

B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.

A gamete that is formed by the meiosis, is a reproductive cell which has haploid set of chromosomes arise from the genotype, the total number of chromosome in mature organism cells.

A a simple method to calculate the number of gametes:

Count the number of heterozygous alleles i.e Aa Bb Cc and Dd which means 4.

           n = 4

Then, total number of gametes will be  = [tex]2^{n}[/tex] or [tex]2^{4}[/tex] = 16

                  Thus 16 in this condition

The 16 types of gametes are formed by this individual by permutation and combination are:

ABCD,  AbCD,  ABcD,  ABCd,

ABcd,   AbcD,   ABCd,   Abcd,

aBCD,   aBCd,   aBcd,   aBcD,

abCD,   abCd,   abcd,  abcD.

Thus, the correct answer is -

B) 1/16 of the gametes produced will be ABcd. C) The individual could make gametes that contain ABCD.
