Only individuals belonging to the same species are able to
True [87]

There are some possible answers which all mean the same thing:

- Produce fertile offspring

- Produce offspring

- Reproduce


→ Only individuals of a same species (sometimes genus) can reproduce because in order to reproduce animals need to have a similar genetic code, and there is now code more similar than the one of individuals of their own species.



Hope it helped,

Question 7 in the attachment, please help thank you so much!
sertanlavr [38]

Answer:

Here are the answers:

a. 4  Cell determination as an issue in the *rest is missing*

b. 4  They assumed that different ways of separating an embryo into two parts would be equivalent as far as the fate of the two parts was concerned.

c. 4  I and III only

Explanation:

The passage demonstrates the importance of two factors in the development of an embryo: cleavage planes of division of embryonic cells and cell differentiation.

Cleavage Planes:

Cleavage basically refers to the division of the zygote into a large number of cells called blastomeres. Cleavage planes are geometrical lines or orientations along which cleavage takes place. Since, all embryonic cells are the precursors of some type of body cells, the cleavage planes determine if the cells are adequate for growth and development.

Cell Differentiation:

Cell differentiation is the transition of an undifferentiated cell into a specialized one. For example, stem cells are undifferentiated cells that develop into progenitor cells that mature into a specific cell lineage. For an embryo to regenerate, the presence of adequate embryonic stem cells is crucial. Embryonic stem cells are present in abundance before the gastrulation phase of embryonic development, after which they rapidly start differentiating.

Action potentials (nerve impulses) are changes in the membrane potential that, once started, will affect the entire excitable me
stich3 [128]

Answer:

The order of events would be:

4.Threshold stimulus, Na+ channels open.  This is the first event

5.Na+ influx, Depolarization. Second event

2.Na+ channels close, K+ channels open.  This is the third event

1.K+ efflux, Repolarization.  Fourth event

3.Hyperpolarization, K+ channels close

Explanation:

In resting state, the membrane is negative inside, and  K+ concentration is higher than outside.   Na+ concentration is higher outside instead.  

Sodium influx is responsible for membrane depolarization.  It's the event to produce the action potential.  When sodium channels are closing, potassium channels open and K+ go outside until repolarization occurs. But now we have both ions in different sides of the membrane, and this can't be stimulated again to produce other action potential. The membrane will remain refractory to respond to the adequate stimulus until ions migrate to their original sites.  This is Na+ outside, and K+ inside.  This is responsibility of the Na+/ K+ pump, that uses ATP to pump Na+ out, and  K+ in. Once both ions had been relocated in the membrane, this is ready to receive a correct stimulus to produce a new action potential.
