Answer:
C. right side of the head and neck and right upper arm
Explanation:
The arch of aorta is a continuation of ascending aorta and terminates at the intervertebral disc of fourth and fifth thoracic vertebrae. The superior part of the arch of aorta branches off into three major arteries. The first branch of arch of aorta is the largest branch and is known as the brachiocephalic trunk.
The brachiocephalic trunk divides and forms the subclavian artery and right common carotid artery. Right common carotid artery supplied blood to the right side of the head and neck while the right subclavian artery delivers blood to the right upper limb.
Hence, any blood clot in the first branch of arch of aorta, that is the brachiocephalic trunk would affect the blood supply to the right side of the head and neck and right upper arm.
Answer:
Threonine has two chiral centers.
The correct options are c. carbon b and d. carbon c
Explanation:
Chiral centers are those that have four different groups of atoms bonded to it. Carbon a has three atoms of hydrogen attached to it so it can't be a chiral carbon. It isn't the carboxyl carbon either since it is double bonded to oxygen. And the amino nitrogen does not qualify anyway because it is bonded to three different groups of atoms, not four.
Many autotrophs make food through the
process of photosynthesis, in which light energy from the sun is changed
to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy, and make ATP. Autotrophs are also called producers. They produce food not only for themselves but for all other living things as well (which are known as consumers). This is why autotrophs form the basis of food chains.
Yes, autotrophs need to perform cellular respiration.
<span>Chlorophyll is essential in photosynthesis, allowing plants to absorb energy from light. Chlorophylls absorb light most strongly in the blue portion of the electromagnetic spectrum as well as the red portion.
The absorption spectrum of chlorophyll a alone underestimates the effectiveness of certain wavelengths in driving photosynthesis. This is partly because accessory pigments with different absorption spectra are also photosynthetically important in chloroplasts and broaden the spectrum of colors that can be used for photosynthesis.</span>
ANSWER: A living organism intakes food, it breaks down into mostly water and large organic molecules. These large organic molecules are Fat, Proteins, Glucose, Starch and Cellulose. These molecules are still not usable by the cells so the body breaks these large polymers into small monomers.
In cow's muscles, protein muscles are built by tapping 4 amino acid monomers. Fat muscles are built by tapping 3 fatty acid monomers and 1 glycerol molecule.
Cows use glucose molecules to mix with oxygen to release chemical energy in cellular respiration. Cows can make fat molecules and glucose molecules because fatty acids and glycerols are made up of same atoms, C, H and O.
