Answer:

Life began inside the water, as it is now scientifically being proved and then after the evolution happened and the land mass appeared there were some abundant form of key energy resources for the different beings to survive and they left water for there terrestrial lives, as different form of animals went on develop the features like having lungs instead of gills, the fore and hind limbs or some of them crawl over the land in order to move from on point to another.  

The first challenge was how to create a protective layer for the body that can protect it from any ray coming from the Sun directly.

The second challenge was that how to breath while being outside the water.

The most important thing was to have a proper body structure to support the organism to live inside the terrestrial environment.

Explanation:

Here, are some of the features which the different animals adapted in order to live on land.

The animals evolved themselves to have a set of lungs instead of having the gills, due to having more atomic form of oxygen inside the free air.

Along, with which the developed the protective covering for them selves to fight and defend them selves from other beings.

Then now had the hind and forelimbs to support there body move from one point on land to another, while having the spinal cord supporting there body.

They developed a new way to haunt by having the exposed bones inside there oral cavity and had the most of its prey by biting them to death.

Along, with which the fertilization process was further improved to provide more options for the beings to cross with each other and have a healthy offspring.

As they had developed there immune system and other senses to fight any pathogen or any type of foreign body that can be hazardous for the whole system.

They now had the  proper way to keep there offspring inside there body while covering it in a more protective layers having all the required amount of nutrients and other materials to develop themselves.

Digiron [165]

Answer: The answer is A: The Inferior Colliculus

Explanation:

The inferior Colliculi play a major role in hearing. Since the loud noise was what prompted the response it is safe to say the inferior Colliculi is responsible.

Neurons in the inferior Colliculi respond to cues such as intensity, the difference red in arrival of sound to both ears.

However, the head snaps up because the information from the inferior Colliculi is transmitted to the superior Colliculi which is involved with movement such as the head.

Which of the following descriptions about RNA is not correct?
gayaneshka [121]

Answer:

The correct answer is option a. "Double-stranded regions of RNA typically take on an B-form right-handed helix".

Explanation:

Most of the native double-stranded DNA is on an B-form right-handed helix, following the structure proposed by Watson and Crick with about 10–10.5 base pairs per turn. However, double-stranded RNA does not follow this structure, and most regions have an A-form structure. The A-form right-handed helix have slightly more base pairs per turn, which makes it 20-25% shorter than B-DNA.

Both myoglobin and hemoglobin exhibit cooperative binding to oxygen. True or False
lys-0071 [83]

Answer:

False.

Explanation:

An Haemoglobin molecule  is made up of 4-polypeptides, with each of the polypeptide chain containing an haem group. These haem group can bind with one oxygen atom each.

T<u>he binding of the first oxygen atom  by the first haem group weakens the tertiary protein   structure  of  Quaternary structure  Hb, thus it makes it easier for the second Oxygen atom to bind faster, and the 3rd oxygen very fast and the 4th oxygen atom the fastest.These accelerated binding of the oxygen atoms, facilitated by the first binding O2, is called cooperative binding.It aids oxygen binding capacity and tranport functions  of Hb,</u>

<u />

<u>Myoglobin is an oxygen storage protein in  muscles, and not oxygen carrying molecule, It releases  stored O2 only in condition of low oxygen supply</u>.It has   one haem group in its molecule.Therefore its structural features can  not  carry out  cooperative binding.
