Two Types of Coevolution

Coevolution is common among organisms participating in a mutual interaction. In mutualism, both the organisms benefit from each other. When coevolution occurs among mutually benefiting species, it is called mutualistic coevolution.

When coevolution is found among species that have negative effects on each other, it is called competitive coevolution. There are two kinds of interactions between species that can lead to competitive coevolution:

<span><span>Predation is when one organism kills and eats another organism. The prey is the species that gets eaten by the predator, which is of course the species that eats the prey.</span><span>Parasitism is when one organism benefits by damaging, but not killing, another organism. The parasitespecies benefits from this relationship, while the host species is negatively affected.</span></span>

We have already talked about another class of chemicals that helps send signals in the body—neurotransmitters. How are neurotr
Darina [25.2K]

Answer:

Similarities: both are chemical messengers, both can have (but don't necessarily have) similar structures (made from amino acids), both can be produced by the central nervous system (hypothalamus produces some hormones), certain molecules can act as both hormones and neurotransmitters (example: norepinephrine).

Differences: neurotransmitters are released by neurons across a synaptic gap, have very short distances to travel, and act very quickly on the neighboring cell. Hormones are released by glands and often have to travel longer distances, which means that they are slower-acting. Also, hormones are typically used for regulation (negative feedback) while neurotransmitters are used for stimulation of a neighboring cell.

I WILL GIVE BRAINLIEST!!!
Nesterboy [21]

Answer:

25%

Explanation:

When looking at a pedigree remember that:

  • squares are males
  • circles are females
  • the solid colored figure represents an individual affected by a disease
  • the empty figure represents a healthy individual

Let us assign the symbol X⁺ to represent the dominant allele linked to the X-chromosome and expressing healthiness, and X⁻ to represent the recessive allele expressing the dissease.

According to this pedigree

  • I1 is a man affected by the disease, YX⁻
  • I2 is a healthy woman X⁺X⁻
  • we can see that among the progeny (generation II) there are two individuals affected (a boy and a girl) and one healthy girl. This means that the mother I2 is heterozygous for the trait.

So, having their genotypes we can know what are the probabilities of getting a son with DMD

Parentals)    YX⁻     x     X⁺X⁻  

Gametes)   Y     X⁻      X⁺     X⁻

Punnett square)

                        X⁺             X⁻

            X⁻      X⁺X⁻         X⁻X⁻    

            Y        X⁺Y           X⁻Y

F1)

  • The probabilities of getting a healthy daughter X⁺X⁻ are 25%
  • The probabilities of getting a healthy son X⁺Y are 25%
  • The probabilities of getting a daughter with DMD X⁻X⁻ are 25%
  • The probabilities of getting a son with DMD X⁻Y are 25%

Sensory receptors in the skin detect the stimuli from the environment.

Explanation:
