(2) DESMOSOMES

(3) GAP JUNCTIONS

(4) GAP JUNCTIONS

(5) DESMOSOMES.

Explanation: TIGHT JUNCTIONS also known as OCCLUDING JUNCTIONS are junctions present between adjacent cells,tight junctions prevent the passage of materials between the extracellular space of cells.

DESMOSOMES are adhesive intracellular junction connecting adjacent cells,they are also known as anchoring joints which are known to present in tissues where stress are expected.

Answer: Dominant

Explanation: If the trait is dominant, one of the parents must have the trait. Dominant traits will not skip a generation. If the trait is recessive, neither parent is required to have the trait since they can be heterozygous. Determine if the chart shows an autosomal or sex-linked (usually X-linked) trait.

spin [16.1K]

Answer:

C) Because apoptosis genes kill cells, natural selection is seldom involved in apoptosis pathways.

Explanation:

Apoptosis is a natural process taking in the cell which causes the physiological and biochemical changes in the cell which could cause the death of the cell.

The apoptosis is controlled at the genetic level therefore apoptosis is also known as the programmed cell death.

The studies have shown that the process is involved in the development of the finger and the toes in humans and the sequences controlling the process has been conserved during the evolution in a different organism.

This shows that humans and nematode have the same conserved sequence of apoptosis but the natural selection does not control the apoptosis.

Thus, the selected option is the correct answer.
