The correct answer is D. 14

Explanation

Ovulation is a phase of the menstrual cycle that occurs on day 14 of the menstrual cycle. This means the evolution occurs in the middle of the menstrual cycle that lasts 28 days and due to this, it occurs14 days after the first day of menstruation and 14 before the beginning of next menstruation. In this phase, the ovule or egg completes its maturation and is transferred to the uterus through the fallopian tubes. Additionally, the uterus is covered and prepared for a pregnancy, this makes the woman be in the most fertile phase to get pregnant; also this phase accompanied by high hormonal levels. So, the correct answer is D. 14

What happens if the correct ligand binds to ligand-gated sodium channel in a post-synaptic neuron?

Maru [420]

Answer:

Post-synaptic neurons after receiving correct ligands called as neurotransmitter in correct amount generates action potential. This action potential may be inhibitory or accelatory.

Explanation:

Postsynaptic neuron :

These are the neurons that is present after the gap called synapse. These neurons after receiving correct ligands called as neurotransmitter in correct amount generates action potential. This action potential may be inhibitory or accelatory.

There are number of neurotransmitter. These includes

GABA ergic: This neurotransmitter is often inhibitory.

glutamatergic: This neurotransmitter is often excitatory.

Adrenergic: This neurotransmitter releases norepinephrine.

Cholinergic: This neurotransmitter activates vertebrate neuromuscular junction.

To test the hypothesis that mussels are osmoconformers, researchers exposed mussels to water of varying osmolarities and then dr

inn [45]

The question is incomplete, I included an attachment that completes the question as well as show the options to be chosen from.

Answer: YES, SUPPORTED

Explanation: When we talk of Osmoconformers, we are talking of the organisms that live in the marine habitat.

These Osmoconformers have the tendency of maintaining their internal fluid isotonic that is isotonic to their external environment in church they live. They have an osmotic pressure that is equal to the osmotic pressure of their surrounding environment.

In the table provided in the attachment section,it clearly stated as we can see the increase in osmolarity of water,the haemolymph osmolarity increase in order to maintain isotonic realtion so that,there will be no much exosmosis (osmosis).
