Answer:

b. epinephrine on beta 2 receptors causes bronchodilation

Explanation:

This is because epinephrine is an hormone and neurotransmitter that stimulate beta 2 receptors which causes signaling and their in presence in airway smooth muscle causes bronchodilation, which counter the activation of the M3 muscarinic receptors in cardiovascular. When stimulate in skeletal muscles it can lead to increased contractility and also to muscle tremors.

In humans, the trait for tongue rolling is dominant over the trait for the inability of a human to roll his/her tongue. If a het
MrMuchimi

50 percent of the offspring would be expected to have the ability to roll their tongues If a heterozygous male is crossed with a homozygous recessive female.

Explanation:

Information given:

the ability to roll tongue is dominant, the genotype would be RR, Rr

the inability to roll tongue is recessive trait the genotype = rr

Given that heterozygous male is crossed with homozygous recessive female, the genotype is

Rr X rr

Punnet square shows that:

    R    r

r   Rr  rr

r  Rr  rr    The genotype ratio is 1:1

                 phenotype ratio is 1:1

There are chances of 50 % offspring having the ability to roll their tongues as they are heterozygous and have the dominant allele for rolling of tongues.

Relate the development of plant needles to the occurrence of mutations.
xxMikexx [17]
<h2>Development of Plant Needles</h2>

Explanation:

  • Seed of pitch pine treated with colchicine delivered tetraploid seedlings which had thick and sporadic needles and less fortunate tallness and diameter growth than ordinary seedlings.  
  • In test of colchicine-initiated polyploidy in pines, researcher found that a significant number of the polyploid plants returned to a diploid development in light of the fact that the polyploid cells partitioned at a more slow rate and were overwhelmed by the more quickly developing diploid cells which encompassed them.  
  • The primary needles of both diploid and polyploid plants were more effective at low light intensity than secondary needles, and they had lower compensation points.

A newly mated queen ant establishes a nest in an unoccupied patch of suitable habitat. Assuming that no disasters strike the nes
Alika [10]

Answer:

Logistic

Explanation:

As the newly mated queen inhabit the new habitat, the population of the ants would increase slowly first followed by a rapid increase in the population size. Once the population size reaches the carrying capacity, it is leveled off.

Carrying capacity is the maximum number of the individuals of a population that can be supported indefinitely by a habitat. Once the population reaches the carrying capacity, one or other required resources become limited which in turn does not allow the exponential growth of the population.

This type of population growth wherein the exponential increase is followed by leveling out the population as the carrying capacity is reached, is called logistic population growth.
