Answer:

Identical Twins

Identical twins share all of their genes and are always of the same sex. In contrast, fraternal, or dizygotic, twins result from the fertilization of two separate eggs during the same pregnancy. They share half of their genes, just like any other siblings.

murzikaleks [220]

Answer:

Explanation:

TransA can be found in the plasma membrane, while TransB is found in the cytoplasm, according to the immunofluorescence localization test analysis. There are two main varieties of serotonin transporters in the neural system when it comes to serotonin signaling.

  • An intracellular transporter that carries and delivers serotonin throughout synaptic vesicles.
  • A transmembrane transporter that prevents hyperactivity overstimulation by re-uptaking serotonin from the synapse.

Therefore, suppose we compare this signaling pathway model to the analyzed experimental test. We can vividly acknowledge that TransA acts as a serotonin reuptake transporter since it is present in the plasma membrane of nerve cells and TransB is a serotonin vesicle transporter that is present and located in the cytoplasm. As a result, the majority of TransB is speculated to be present in synaptic vesicle membranes.

C as: CD CE CF CG CH CI CJ

D as: DE DF DG DH DI DJ

E as: EF EG EH EI EJ

F as: FG FH FI FJ

G as: GH GI GJ

H as: HI HJ

I as: IJ

Adding all the combinations together = 45

In other words;

^{10}C_2 = \frac{10!}{(2!(10 - 2)!)} = 45

<span>The experiment performed by Francesco Redi supports the hypothesis that fly larvae only come from adult flies based on his experiment design using a covered-meat and non-covered meat. In addition, he also believed that maggots came from the fly rather than from the rotten meat by using the same experiment design. </span>
