Is there any great similarity between the muscle structure and muscle arrangement in the cat and humans?

1 answer:

6 0

The similarity in the arrangement and structure exists mostly with the quads because we, just like cats, need to be able to flex and extend them so we need a lot of strength in them.

Chromosomes are composed of deoxyribonucleic acid (DNA) mole

There are mainly two molecules that function as genetic material in living organisms.

These are ribonucleic acid(RNA) and deoxyribonucleic acid(DNA).

The organisms having DNA as genetic material require packaging of DNA as it is a long polymer of deoxyribonucleotides.

In the case of human beings, the length of DNA in a cell is approximately 2.2 meters which is very large as compared to the size of the nucleus( approximately 10^-6 meters).

So, the DNA has to be made compact for it to be present inside the nucleus of a cell.

Therefore, the DNA present inside the nucleus of a cell undergoes coiling and compaction through several stages before finally becoming a chromosome, which is shown in the adjoining diagram.

Thus, chromosomes are composed of deoxyribonucleic acid (DNA) molecules.

List the ocean regions that have the highest sea surface salinity

AlladinOne [14]

Answer:

The high sea surface salinity can be observed in the Pacific Ocean, the Indian Ocean, the Arabic ocean and the Mediterranean sea.

Explanation:

Due to rainfall and evaporation of water from sea the density varies with varying salts and minerals concentration that aggregate at the surface. The salinity in the seawater varies according to the amount of evaporation from a particular area.

Low salinity water is found in polar and subpolar regions that are near to the equator. Regions of high salinity are observed in the seawater which is centered around 30 degrees north and 30 degrees south to the equator due to the excess evaporation in these areas.

The proton motive force (pmf) is driven by __________. the proton motive force (pmf) is driven by __________. the pumping of pro

RideAnS [48]

When a cell membrane becomes energized due to electron transport reactions by the electron carriers embedded in it then this results in proton motive force (PMF). This way the cell becomes a tiny battery. 
The proton motive force (PMF) is driven by the difference in charge across the plasma membrane with protons outside the membrane.
