X-linked genes differ from Y-linked genes in which of the following ways?

Biology
1 answer:
lana [24]3 years ago
3 0

Answer:

e) Sons and daughters have equal probabilities in inheriting a recessive allele of an X-linked gene from their mother, but only sons can inherit rare Y-linked genetic disorders from their father.

Explanation:

Females have two copies of the X chromosome and males have only one X chromosome (one Y chromosome). Because of that X-linked recessive diseases are more common among males than females (males need only one copy to have disease, females with one copy are carriers).  

For example, if a mother is a carrier (has only one allele that is associated with disease), she can transmit either the X chromosome with the mutation or an unaffected X chromosome to her children. If the father is unaffected, all of the daughters will be unaffected—since they will inherit at least one normal X chromosome from their father. But, son can be affected, because he inherits Y chromosome from father and can inherit affected X chromosome from mother.

Clouds reflect a large portion of the sun's energy, so if cloud cover declines, the amount of energy absorbed by land and oceans would increase, causing a temperature increase as well.

How do photosynthesis and respiration work together to produce energy to support
FinnZ [79.3K]

Photosynthesis and respiration work together by creating the energy and transporting it.

The process are similar because they both take something in, and let something else out.

The processes complement eachother by Respiration being able to take oxygen to the leaves, and the leaves using that oxygen to power their chemical reaction.

Good luck there friend!

Why does the reduction of the dye DCPIP work best using the chloroplasts whose outer envelopes have been damaged during preparat
Stolb23 [73]

Answer:

NADP is the cofactors in photosynthesis which loses electrons,becomes reduced(NADPH) in photosynthesis. It transfer  electrons  in reduced form(NADPH) into the stroma of the chloroplast. The H is splits into e- and H+

These electrons for the ETC chains, generates the PMF for pumping H+ as protrons into the thylakoid  intramembranes.

Outer membrane covers  the intramembrane space, between these two membranes layers. The protons in the intramembrane space generate the electrochemical gradient for the supply of  the energy used by ATPase synthase for ATP synthesis from phosphorylation with ADP.

The chloroplast is made up of both the outer and inner membrane,separated by the intramembrane space. The walls of the intramembrane space is guided by the outer envelope. 

Therefore with the outer envelope removed, the intramembrane is exposed,more protons(H+) are released, but can not be held in the outer envelope to form electrochemical gradients,beacause the intramembrane space is now permable.

Thus   the rate of reduction of DCPIP is faster.The  color changes to colorless increases when reduced , from blue color.

Pick only ONE sentence Which sentence from the section shows why the right temperature is important for plants? (A) Temperature
Arisa [49]

Answer:

The correct answer is - (B) As with any living thing, a plant has an optimal temperature range at which it grows and performs best.

Explanation:

Like any other or most of the living organism, plants also required an optimal temperature range as they also required appropriate temperature for their growth and development and perform their functions at their best.

Optimum temperature range is a temperature range at which something performs its best similarly plants perform their cellular functions like photosynthesis, metabolism, reproduction, and many other functions that require a particular temperature range.
