This is a form of asexual reproduction because Asexual reproduction is a form of reproduction where a single celled organisms or muiticellular organisms produce or divide to produce offsprings that are genetically identical without fusion of gametes and exchange of genetic materials.

This type of reproduction includes binary fission( where an organism divides into two), fragmentation( where an organism divides into fragments), budding, spore formation e.t.c.

If the marginal propensity to save is 0.25, a $15 billion increase in government spending will lead to an increase in national i
Greeley [361]

Based on the marginal propensity to save, MPS , the national income will increase by a maximum of $20 billion.

<h3>What is marginal propensity to save?</h3>

Marginal propensity to save (MPS) is a measure of how savings will change, given a change in income.

Marginal propensity to save is related to marginal propensity to consume, MPC by the formula:

  • MPS + MPC = 1

Grom the given value of MPS,

MPC = 1 - 0.25

Therefore, MPC = 0.75

Also, the formula for calculating marginal propensity to consume is given as:

  • Marginal propensity, MPC = ΔC/ΔY

Where:

  • ΔC is a change in consumption
  • ΔY is a change in income

ΔY = ΔC/MPC

ΔY = $15 billion/0.75

ΔY = $20 billion

Therefore, the national income will increase by a maximum of $20 billion.

In humans, the hormone testosterone enters cells and binds to specific proteins, which in turn bind to specific sites on the cel
LuckyWell [14K]

Answer:

As a transcription factor

Explanation:

Testosterone is a male sex hormone secreted by the testicles which promote the growth of the male reproductive organs and the male characters like muscle buildup.

The hormone shows the paracrine effect and thus act on the target cell at distant. The mechanism of action of the testosterone is that it controls the gene expression of various other genes.

The testosterone binds the specific proteins which activate the expression of the gene that is they acts as a transcription factor which activates the expression.  

Thus, as a transcription factor is correct.
