What structural component gives arteries the ability to passively adapt to changes in blood pressures that accompany the heartbe
Andrews [41]

Answer: elastic fibers

Explanation:

Elastic fibres are the essential durable component present in mammalian connective tissueand functions to provide proper pulmonary,  cardiovascular and intestinal system structure and function. Their structural function is to provide elastic recoil and resilience for the tissues.

Elastin fibers ahve two main including microfibrils and elastin containing fibrillin play a mechanical and structural role in the arteries, and their important function is to provide the tissues with resilience and elasticity.

Hence, elastic fibers helps arteries to adapt to changes in blood pressures that accompany the heartbeat.

Anuta_ua [19.1K]

Answer:

0.7

Explanation:

Using Hardy-Weinberg equation of genetic variation being constant when disturbing factors such has mutation and others are removed.

p² + pq + q² = 1 and p + q = 1

where p² is the frequency of the homozygous dominant genotype (RR) and q² is the frequency of the homozygous recessive genotype (rr) and 2pq is the frequency of heterozygous genotype (Rr). p represent the frequency of "R" and q represent "g". since the coefficient against the green/green homozygote is 0.30 then

the fitness of the green/green homozygote = 1 - 0.3 = 0.7

Parents with the dominant phenotype cannot have offspring with the recessive phenotype.
disa [49]

Answer:

False, they can have recessive phenotype

Explanation:

A phenotype is a viable characteristic an individual presents as a consequence of the interaction between its environment and its genotype.

This doesn’t necessarily means that the individual’s aleles are both dominant (homozygotes), they could have one dominant and one recessive gen (heterozygotes), meaning that, if the another parent is homozygote with both recessive aleles the offspring could heritage homozygote recessive aleles that will result in a recessive phenotype.

You can observe in the image I added a punnet square that exemplifies the scenario. You can see that the offspring has 1/2 probability to have recessive phenotype.

I hope you find this information useful and interesting! Good luck!
