Answer:

The correct option is A: Mass activation

Explanation:

The flight-or-fight response that gets activated in these type of situations is attributed to the sympathetic nervous system. It causes the release of adrenaline into the bloodstream and several other changes occur, as mentioned in the question statement, these changes prepare the body to react promptly to the situation at hand.

Hope that answers the question, have a great day!

Answer:

The answer is C.

Explanation:

The sympathetic nervous system (SNS). it is predominant in dangerous situations.

It provokes the appropriate actions for rapid response such as: increased heart rate, dilated bronchi to promote the entry and exit of gases, increased sweating, decreased intestinal peristalsis to decrease the energy invested in digestion, vasoconstriction of the arteries, dilation of the pupils so that more light enters, etc.

For this reason axons quickly send a response to all these organs through the sympathetic nervous system.

Corn develops from a seedling with a single cotyledon, displays parallel veins on its leaves, and produces monosulcate pollen. I
Rzqust [24]

Answer:

a monocot

Explanation:

Monocotiledoneas are plants that develop from a seedling with a single cotyledon. That is why we can say that maize is a monocotyledon.

Monocotyledons and dicotyledons are two classes of vegetables that belong to the angiosperm plants (plants with seeds contained within the fruits) and also phanerogams (flowering plants), currently classified as magnoliophytes, gathering approximately 230 thousand species. Monocotyledons are plants that have only one cotyledon in the seed. Cotyledons are the initial leaves of plant embryos.

What are the chances that a kitten born would have a DIFFERENT genotype than the sister's cat Moo?
Strike441 [17]

A kitten born will have genotype different from sister because the concentration of gene expressed is different in all kittens as it is a phenomenon of codominance.

Explanation:

The moo cat is black and white bicolour cat.

The cat has white colour fur which is combined with some other colour as black.

White colour in cat has white spotting gene that prevents the patches over cat's body.

SS genotype results in large concentration of white colour.

Ss results in medium concentration of white colour.

ss results in black or other dark colurs with very meager or no white colour on skin.

The resultant colour appearance of skin in cats is due to codominance. The colour of the skin depends on the concentration of gene and protein expressed. So, the sister moo cats can have diffrent genotype and different level of white colour patches on the skin and genotype of SS,Ss or ss can be there in sister kittens.
