Answer:
Integrins.
Explanation:
Integrins may be defined as the transmembrane ligand that activates the signal transduction pathway by binding with its receptor. Integrins is present in all animal cells.
Integrins helps in the direct communication of the cell with the extracellular matrix. The specific gene expression occur in liver and testes. Integrins are involved in the induction of the cell and their communication with the extracellular matrix.
Thus, the answer is integrin.
False. I don’t know how to explain it
Answer:
A) Stage 1
Explanation:
Demographic transition has to do with the changing pattern of factors that impact population such as birth rates, death rates as the population moves from regime to regime. The transition is in four stages:
- <em>Stage 1: which is characterized by high high birth and death rates. ALso known as pre-transition stage.</em>
- <em>Stage 2: Characterized by falling death rate but continued high death rate. Also known as early transition stage.</em>
- <em>Stage 3: characterized by a decline in birth rate and deceleration of population growth. It is also known as late transition period.</em>
- <em>Stage 4: Characterized by low birth and death rate. Negligible population growth. Also known as post-transitional period.</em>
The correct option is A.
