Explanation:

There are two compositions in blood.

1. Plasma (55%)

2. Blood cells (45%)

Again Blood cells is divided into:

RBC ( Red blood cell)

It transports oxygen for respiration.

WBC ( White blood cell):

They help in the formation of antibodies to fight against germs and bacteria.

Platelets:

It plays major role in healing of the wounds.

The option that best illustrates the similarity and difference in the elemental makeup of these molecules is that carbohydrates and lipids both contain carbon, hydrogen, and oxygen atoms, while the proteins contain nitrogen in addition to those three elements. That is option B.

Carbohydrates are macromolecule found is food substances that plays a vital role of energy supply to the body.

It is made up of chemical elements such as carbon,hydrogen and oxygen in the ratio of 1:2:1.

Lipid is another macromolecule found in food which is an energy reserve for the body.

Lipids are made up of elements seen in carbohydrates such as carbon, hydrogen and oxygen but contain many more hydrogen atoms than oxygen atoms.

Proteins are another type of macromolecule found in food which helps in body building and repair of worn out tissues.

Proteins are made up of elements seen in carbohydrates and lipids with the addition of nitrogen atom.

Therefore, carbohydrates and lipids both contain carbon, hydrogen, and oxygen atoms, while the proteins contain nitrogen in addition to those three elements.

Mutations in DNA include deletions and insertions. These types of mutations:

pantera1 [17]

Answer:

(A). Result in different amino acids to be read due to frame shifts

Explanation:

Insertion or deletion mutations (or Indel mutations) can be defined as mutations in DNA due to insertion (addition) or deletion of nucleotide bases in DNA.

These mutations lead to change in reading frames (sequence of codons), which leads to formation of protein having completely different amino acid sequence. Hence, these mutations are also cause frameshift mutations.

This is due due to triplet nature of genetic codes as insertion or deletion of one or more bases (but not three) would change change in codon sequence and mutated sequence can form a non-functional or truncated protein.

Thus, the correct answer is option (A).

In the human life cycle, diploid cells undergo a cell division process called __________. The resulting haploid cells later fuse

7nadin3 [17]

Answer: Meiosis; fertilization

In the human life cycle, diploid cells undergo a cell division process called meiosis. The resulting haploid cells later fuse during fertilization which regenerates diploid cells.

Explanation:

Diploid cells possess two basic sets of chromosomes known as homologous chromosomes. They undergo a two-step meiosis (Meiosis I and II) to yield four haploid cells with half the original chromosome number of the parent cell. These haploid cells are called sex cells or gametes.

The male and female gametes (sperm and egg) then fuses during fertilization to form zygote, a single cell with two sets of chromosomes (diploid number). Then, it undergoes mitosis to regenerates diploid cells with the same chromosome number as found in the zygote.

What structure contains the digestive enzymes of a chelicerate?

Sliva [168]

The correct answer is midgut.

The guts of most modern Chelicerates are too narrow for digesting solid food, so the Chelicerates liquidize their food. Some of them do that by pumping the digestive enzymes<span> from the midgut into the prey and then suck the liquefied tissues of the prey.</span>
