The best answer i see is A)- Cooling  

i hope this is right and it helps you

Answer:

Earth's initial atmosphere probably contained higher levels of water vapor than today's atmosphere. Most of the water vapor left the atmosphere due to the a) cooling of the earth.

Explanation:

To understand this answer we need to understand the characteristics of cold and hot air. First of all, hot air or in this case water vapor due to physics tends to go up, while cold air or vapor tends to go down. This can be observed in the process of raining. Vapor always goes up and comes down to earth in the form of water, mist or snow. However, in that time the vapor didn't come down and kept going up because the atmosphere was not developed and the earth's cooling was responsible for that. Because it didn't have the pressure and gravity it has today.

Answer:

[tex]\boxed{\bf~A.}[/tex]

A little basic info:

Chromosomes are molecules of DNA that carry groups of genetic information. Some genes group up in the same chromosome, and this it what we'll see below.

Why are linked genes inherited together? What are they?

This question is more simple than it looks, since there's really little to explain. Linked genes, are genes inherited through the same chromosome:

→ When 2 genes tend to group-up on the same chromosome, they tend to be inherited together, but still, this doesn't happen always and the probablity of this happening is just slightly above 50%.

Remember:

Only genes that sit close together on a chromosome are likely to be inherited together, because if they're to far apart in the chromosome, the process of (homologous) recombination might separate them.

→ To make things simple, homologous recombination is when similar DNA moleculas are moved and recombined in a different way.

The reason that linked genes are inherited together is Linked genes are inherited together because they are located close to each other on the same chromosome.

The correct answer is A.

During the process of meiosis, which is responsible for the formation of gametes (sperm and eggs), homologous chromosomes pair up and can exchange segments of genetic material through a process called recombination or crossing over. However, when genes are located very close together on the same chromosome, the likelihood of recombination between them is reduced. As a result, these genes tend to be inherited together as a unit, maintaining the linkage between them.

The phenomenon of linked genes was first described by Thomas Hunt Morgan in his studies on fruit flies, where he observed that certain traits were consistently inherited together due to their close proximity on the same chromosome.

Hence , A is the correct option

C. Tendons

Tendons are connective tissues that are able to attach muscles to bones. They are found through out the body especially at the end of each muscle. Including the human eyeball where tendons are used to connect muscles to other parts.

• Fascicles are fibers which cannot be attach skeletal muscles to the bone.

• Ligaments are connective tissues which connect bones to joints.

• Flexors are muscles that are able to stretch a body part.

Skeletal muscle cells are attached to bones by tendons, which are tough connective tissues that enable the movement of bones at joints when muscles contract.

Skeletal muscle cells are usually attached to bone by tendons. Tendons are tough connective tissues that connect skeletal muscles to the skeleton, allowing for the movement of bones at a joint. When muscles contract, the tension is transmitted through these tendons which in turn pull on the bones, facilitating movement.

Tendons are composed of dense, regular connective tissue and are integral for the interaction of skeletal muscles in the body. This connection to bones is crucial for muscles to perform functions like maintaining posture, stabilizing bones and joints, controlling internal movement, and generating heat.

The answer is; C

Gene therapy is still not considered safe and has not been approved for humans, especially due to errors in inserting of DNA at the target site and also random relapse of the DNA from its inserted site. Gene therapy, however, can be sanctioned when its benefits outweigh its risks such as in terminally ill patients - with the approval of the patient and local relevant policies/authorities. Gene therapy, today, is being tested with innovative tools called CRISPR/Cas9.

Answer: C) still being tested and is used for diseases that have no cure.

Explanation: It is considered as risky and is only used for diseases with no cures. It's not used for those diseases with many cures and it is not safe.
