a) cats

(b) Toads

(c) The fish

(d) alternative b and c

Answer:

(a) Los gatos

Explanation:

Only cats are capable of internal fertilization from the given choices above.

Internal fertilization is the fusion of gametes within an organism. This process occurs during sexual reproduction within the female.

  • Toads and fishes exhibit external fertilization.
  • External fertilization occurs where the male sperm externally fertilizes the eggs of the female.
  • This usually takes place in a moist or wet place especially water bodies. The liquid medium will transport the sperm to the egg.

C) Poison detoxification : Smooth endoplasmic reticulum.

D) Protien synthesis : Rough endoplasmic reticulum.

E) Protien modification and sorting : Golgi apparatus

F) Cisternal maturation : Golgi apparatus.

G) Macromolecule digestion : Lysosomes

H) Autophagy : Lysosome.

Explanation:

<u>Smooth endoplasmic reticulum</u> is involved in the synthesis and storage of lipids . It also stores the calcium ions and contain enzymes responsible for the detoxification of the poisonous substances like CCL4 and other agents. SO the answer of A , B  and C is Smooth endoplasmic reticulum.

<u>Rough endoplasmic reticulum</u> contains ribosomes which synthesize protiens thus answer of D is RER.

The <u>Golgi apparatus</u> functions as a factory in which the protiens recieved from the endoplasmic reticulum are modified and sorted and is also involved in cysternal maturation so answer of option E and F is Golgi apparatus.

<u>Lysosomes</u> are the part of endomembrane system involved in the digestion of the macromolecules and in the recycling of the worn-out organelles hence also involved in autophagy. Hence answers of G and H is lysosomes.

Aneli [31]
There are choices for this question namely:

Ativan 1 mg orally 
<span>Nitroglycerin SL </span>
<span>Serum electrolytes </span>
<span>Chest x-ray
</span>
The correct answer is "Nitroglycerin SL". The SL means sublingually. The physician will still order Nitroglycerin to be taken sublingually whenever there is chest pain. The patient's medication may have been expired being stored for 12 months now. Ativan or Lorazepam will not be given as this is a sedative and there is no indication for sedatives.

Serum electrolytes and chest xray will not be requested as these diagnostic examinations are not usually done in patients with stable angina.
