Answer:

dna could be used for food by bacteria

Explanation:

not a beneficial reason

All of the following reasons are beneficial for prokaryotes to take up foreign DNA except the use of DNA as food by bacteria. Thus, the correct option is A.

DNA uptake is defined as the conversion of exogenous, DNase-sensitive DNA into a DNase-protected state inside a bacteria. In gram-negative bacteria, this DNA uptake can be achieved by crossing the outer membrane. By contrast, in gram-positive bacteria, DNA uptake is similar to gram-negative bacteria with passage across the cytoplasmic membrane.

The uptake of DNA in bacteria is beneficial as it helps in the production of recombinants that can be used for various purposes. The DNA uptake can be used for the repairing of damaged DNA and chromosomes in patients of genetic disorders.  

New genes with different functions can be introduced in organisms like bacteria.

Therefore, the correct option is A.

The only body structure that has walls one cell thick is capillaries.

Capillaries, the blood vessels in our bodies are so minuscule that red blood cells can only travel through them in a line. Comprised of a layer of cells capillaries facilitate the exchange of crucial substances like oxygen carbon dioxide, nutrients and waste materials, between the bloodstream and the surrounding tissues.

With the above details we can conclude that the  body structure that has walls one cell thick is capillaries.

Answer:

Epidermis.

It is composed of keratinized, stratified squamous epithelium and is made up of 4 layers of epithelial cells depending on its location in the body. From deeper to superficial these layers are stratum Basale, stratum spinosum, stratum granulosum, and stratum corneum. The cells in all the layers except for stratum besele are called keratinocytes which is a cell that manufactures and stores the protein keratin.

Stratum Basale.

It is a cuboid-shaped stem cell that is a precursor of the keratinocytes of the epidermis. Two other cell types found in this basal cell are Merkel cells which function as a receptor and are responsible for stimulating sensory nerves that the brain perceives as touch. The second is melanocyte that produces melanin pigment which gives the skin its color.

Stratum spinosum.

It is spiny in appearance due to the protruding cell processes that join the cells via a structure called desmosome. The desmosome cell interlock with each other to strengthen the bond between the cell. Keratinocytes in the stratum spinosum stats synthesizing keratin and release water-repelling glycolipid that helps to prevent water losses from the body.

Stratum granulosum.

They are grainy in appearance due to further change in keratinocytes as they are pushes from the stratum spinosum. The cells become flat as their membrane thickens to allow the production of protein keratin which accolades as lamellar granules within the cells.

Stratum Lucidum.

It is a smooth and translucent layer of the epidermis situated above the stratum granulosum. Keratinocytes containing these cells are dead and flat. Stratum lucidum cells are packs with eleiden derived from keratohyalin which give these cells their transparency and provide a barrier to water.

Stratum corneum.

This is the most superficial layer in the epidermis and it prevents penetration of microbes and dehydration of underlying tissues.

Dermis.-This is the inner layer of the skin and has the following functions.

Reticular layer

Just below the papillary layer, we have a much thicker layer called the reticular layer composing of dense connective tissue. It contains elastin fibers providing elasticity to the skin enabling movement.

The correct answer is - secondary succession.

Explanation:

Recolonization of the plant and animals to habitat after a major disturbance such as flood, lava eruption, wildfire, or human disturbance is characterized as secondary succession.

Recombination frequency determines if two genes are linked or if they segregate independently from each other. The recombination frequency between E and H is 8%

Linked genes are those that are too close to each other in the same chromosome and they do not segregate independently.

These are the linked genes that do not exhibit an independent distribution, and they are inherited together more frequently.  

Recombination frequency can be defined as the crossing over events  frequency occurring between two genes.

The value of recombination frequency indicates weather genes are linked or not. The maximum recombination frequency is always 50%.

When RF is 50% or more, we can assume that genes are not linked.

In the exposed example, we can recognize the parental gametes in the descendants because their phenotypes are the most frequent, while the double recombinants are the less frequent.

Parental)

426 Ee hh bb

Double recombinant)

4 Ee Hh Bb

2 ee hh bb

Simple recombinant)

48 ee Hh bb

36 ee hh Bb

46 Ee hh Bb

38 Ee Hh bb

We will call Region I to the area between genes E and H and Region II to the area between genes H and B.

------------E------------H--------------B-----------

              /---RI------//------RII-----/

To calculate the recombination frequency between E and H we just need to consider region I. We will call P1 to the recombination frequency in this region.

P1 = (R + DR) / N

Where:

Now, let us analyze the information.

We know that individuals carrying double recombinant gametes are

We know that the recessive parent from the testcross could only provide the following gametes ⇒ ehb

This leads us to assume that the followings are the double recombinant gametes from the trihybrid parent,

Since these gametes are the product of a double recombination event in region I and II, we can assume that the parental gametes of the trihybrid individual are

Hence the simple recombinant gametes in region I are

Now, according to this analysis, we know that

Simple recombinants in region I

36 ee hh Bb

38 Ee Hh bb

Double recombinants

4 Ee Hh Bb

2 ee hh bb

Total number of individuals

N = 1000

Recombination frequency in Region I

P1 = (R + DR) / N

P1 = (38 + 36 + 4 + 2) / 1000

P1 = 80 / 1000

P1 = 0.08 = 8%

The recombination frequency between genes E and H is P1 = 8%

Two pieces of information that scientists use to prepare evolutionary trees for living and extinct organisms are the fossil evidence that is found on the earth and the DNA samples, as these two are helpful in the evolutionary tree representation.

An evolutionary tree, or phylogenetic tree, is a diagrammatic representation that shows the relationships between different species or groups and is used to represent the evolutionary history and how organisms are related to one another through common ancestry. The evolutionary tree is important as it helps scientists understand the relationships between different species and how they have evolved over time to form new species.
