<span>Creation of egg cells and production of estrogen and progesterone, I think but I'm pretty sure it would be easier if I could see the diagram.</span>

Answer:

The most appropriate answer would be the first option.

The given description best describes the structure of Bicornuate uterus, that is, heart-shaped uterus.

It is a hollow structure made up of three tissue layers. The large canal (cervix) extends from the lower part of the uterus which connects it to the vagina.

In addition, two fallopian tubes (one from each ovary) connect to the uterus.

The fertilized egg or zygote from the fallopian tube is delivered to the uterus where it gets implanted into the endometrium layer.

The uterus protects and nourishes the developing embryo until it is ready for birth.

azamat

Answer:

This question lacks options, options are: Mr. M's cells are depolarizing too easily. Blocking Nat channels will make it harder for them to depolarize, bringing their sensitivity back to normal O Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Kt channels can stay open and his cells can repolarize properly. Mr. M has too little K* leaving his cells, so we need to block the Nat channels so the Na /K+ ATPase can move Kt out of the cell effectively O Blocking Na* channels cannot help- it will only make his cells fire less, and he already has a weak heartbeat. Mr. M's cells are not repolarizing properly. Blocking Nat channels will help them repolarize normally, bringing their resting potential back to normal.

The correct answer is ''Mr. M's cells are depolarizing too easily. Blocking Na+ channels will make it harder for them to depolarize, bringing their sensitivity back to normal.''

Explanation:

Calcium administration is an emerging treatment modality aimed at restoring the transmembrane electrical gradient of cardiac myocytes. It probably achieves this goal by reducing the resting membrane potential of cells. Calcium antagonizes the effect of hyperkalemia on cardiac conduction, that is, it antagonizes the effects of K on the heart. Its onset of action is immediate, in a few minutes. Calcium gluconate antagonizes the excitability of the cardiac membrane, that is, it decreases the excitability of the membrane and it does not affect serum levels, it is generally accepted that calcium should be administered when there are ECG changes associated with hyperkalemia.
