Explanation:
<u>a. The genes in the DNA instruct the cell to make proteins.</u>
Genes are a set of coded instructions in the form of DNA, which are crucial to cell regulation - these enable protein synthesis.
Further Explanation:
Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They differ from other macromolecules since they don’t provide the body with energy. They exist solely to encode and carry out protein synthesis.
All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is condensed and tightly wound around histones as chromosomes. Chromosomes within the nucleus is unwound, unzipped and read by enzymes in a complex series of steps known as transcription. The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand. These are then translated into proteins in ribosomes.

The ribs articulate with the (a) thoracic vertebrae.
There exists 12 pairs of ribs. Each rib is a thin flat bone attached dorsally to the vertebral column as well as ventrally to the sternum.
First seven pairs of ribs are known as 'true ribs'. They articulate with the thoracic vertebrae dorsally and are ventrally attached to the sternum by means of of hyaline cartilage.
The 8th, 9th as well as 10th pairs of ribs do not articulate directly with the sternum but unite with the 7th rib with the support of hyaline cartilage. These are called 'false ribs'.
Remaining two pairs i.e. the 11th and 12th pairs of ribs are not attached ventrally and are thus, termed as 'floating ribs'.

Answer:
It is an ongoing process because species and communities continue to evolve over time.
Explanation:
The function of acetylcholinesterase in the synaptic left is to bind Ach receptors on the post-synaptic membrane and relays signal from the nerve. Acetylcholinesterase is an enzyme that catalyzes the breakdown of acetylcholine. Some other cholines functions as neurotransmitters. ACHE gene is found in the chemical synapses and neuromuscular junctions of cholinergic. Acetylcholinesterase belongs to carboxylesterase group of enzymes. During the time of neurotransmission Ach which is released from presynaptic neuron to synaptic cleft. Acetylcholinesterase is also found in red blood cells membranes whereby different forms constitute the Y blood group antigens.
Answer: B
Explanation:
A cell membrane acts like a rain coat or a sweater, keeping certain things in and certain things out.
