What happens to the genetic material before the cell divides

Answers

Answer 1

Because each chromosome is made from a single molecule of 'DNA', before a cell divides itself, it had to replicate and copy its DNA. This makes it so that after cell division, each new cell holds an exact copy of the genetic material from the original cell.

How nucleotides are arranged in DNA?

Two nucleotides are attached via a phosphodiester bond to form dinucleotide. Another  nucleotides are added in same manner to form polynucleotide chain.

which statement regarding normal microbiota of the human respiratory system is false?

Answers

Given what we know about the respiratory system, we can confirm that the statement regarding normal microbiota of the human respiratory system that is false is option B " The upper respiratory tract is mostly sterile".

As far as the human respiratory tract and system, it was previously believed that the upper tract contained bacteria while the lower respiratory tract was sterile. Recently, however, this has been proven to be false. Bacteria are in fact present in the entire respiratory tract even in healthy individuals. For this reason, options a, c, and d are true, and the only false option present is b.

This question was answered based on the complete question found online that states:

Which statement regarding normal microbiota of the human respiratory system is FALSE?

a) The trachea normally may contain a few bacteria.

b) The upper respiratory tract is mostly sterile.

c) The ciliary escalator in the bronchial tubes keeps the lower respiratory tract nearly sterile.

d) Potentially pathogenic microorganisms are present in non-sterile portions of the respiratory tract but usually do not cause disease.

Based on information from the cladogram and the data table shown below, which of the following best describes the evolutionary history of rabbits?


Claws/Nails Feathers Jaws Lungs Mammary glands
Bird X X X X
Hagfish
Lizard X X X
Rabbit X X X X
Salamander X X
Tiger X X X X
Trout X


Image depicts a cladogram with hagfish, trout, salamander, lizard, bird, rabbit, and tiger represented. Trout diverge from hagfish with the introduction of jaws. Salamander diverges from trout with the introduction of lungs. Lizard diverges from salamander with the introduction of claws and nails. Bird diverges from lizard with the introduction of feathers. Rabbit and tiger diverge from lizard with the introduction of mammary glands.
They are more closely related to tigers than they are to birds.
They became able to produce mammary glands as a result of lacking feathers.
They evolved into a separate species due to the presence of mammary glands.
They share a more recent common evolutionary ancestor with salamanders than they do with lizards.

Answers

Answer:

A. They are more closely related to tigers than they are to birds.

Explanation:

Short answer: I took the test

Actual explanation:

-If you look at the first graphic that you have, you will notice that rabbits and tigers have all the same boxes checked off. AND birds and rabbits only have 3 checked off.

-salamanders actually have less in common with rabbits than they do with lizards, salamanders have 3 things in common, and lizards only have 2, proving option D. wrong. (if you are wondering where I got that evidence, look at the chart) AND if you look at the cladogram, lizards are closer to the rabbits than salamanders meaning that lizards have a more common ancestor (I think?) But nevertheless, it it still wrong, because of the above evidence.

- The options with mammary glands are also incorrect for these reasons, B. makes no sense, literally no sense, why would not be able to produce mammary glands with feathers, so B, is automatically out. With option C, rabbits did not evolve into a whole new species, it is the clade showing that tigers and rabbits both have mammary glands. There is no showing of a new species on the cladogram, and I don't think that it makes sense to evolve into a whole species just because of mammary glands.

- Now, if you look at the cladogram again, you wills see that tigers and rabbits are closest together, meaning that they are closely related. BUT, birds and rabbits are also the closet together, so, refer back to point a, that the chart shows that birds only share 3 out of the 4 that rabbits and tigers share. so that's that.

So after doing the work, option A. Rabbits are more closely related to tigers than they are birds. (and If you read my long explanation THANK YOU I put time and effort into it to make it accurate :))

Hope this helped :))                                                                                                    ~addison

Answer:

The place where a group of organisms lives is called the habitat. The combination of the community and habitat is called the ecosystem.

What is habitat and ecosystem?

An ecosystem is basically the neighborhood where animal lives. The habitat is the animal's address in that neighborhood. Some animals can survive in more than one habitat. Other animals are limited to certain habitats. For example, moose habitat is more specific than gray squirrel habit.

Moreover, ecosystem is defined as the interrelationships between the biotic and abiotic component of the environment. Whereas habitat is defined as the natural environment in which a particular species of plants and animals lives.

Therefore, a habitat is a place where an organism makes its home. A habitat meets all the environmental conditions an organism needs to survive. For an animal, that means everything it needs to find and gather food, select a mate, and successfully reproduce.

why do x-linked conditions appear more frequently in males than in females?

Answers

Answer:

Because, with females, who have two x-chromosomes, meaning both parents (mother and father) have to pass down alleles for the condition, and males only need one parent (mother) to pass down the condition for the male to have the mutation

X-linked conditions appear more frequently in males than in females because:-

In males there is only one X chromosome.Any X linked condition will appear in males as there will no other X chromosome to dominate it.In female there are two X- chromosome. If any one of the two X chromosome has defect other chromosome will dominant it and will the female will act as a carrier.

What are X linked disorder?X-linked disorders are caused by variants in genes on the X chromosome, one of the two sex chromosomes in each cell. In males who have only one X chromosome, an alteration in the only copy of the gene in each cell is sufficient to cause the condition.

different types of cells in your body look and function differently. the basis for these differences is:

Answers

Different types of cells look and function differently, the basis for these differences is DIFFERENT PATTERNS of gene expression. This process (differential gene expression) leads to cell specialization.

Gene expression refers to the process by which the genetic information flows from a DNA sequence (i.e., a gene) to an mRNA molecule and finally to a protein.

In somatic (body) cells, the differential patterns of gene expression lead to the generation of different proteins and ultimately to different types of cells (cell phenotypes).

In consequence, cells are specialized to perform specific functions because different genes are being expressed.
