Answer:

First Trimester stage of Pregnancy

Explanation:

The first 3 months of pregnancy is called the First Trimester.

This stage is the most critical stage as there is a lesser chance of miscarriage after getting past this stage and the major organ system are formed. The baby’s brain isn’t fully developed yet and the sex is still unknown at this stage. The baby also weighs less due to the underdevelopment.

During gym class, Raul walks briskly for a half hour. Jenna decides to sprint and run the bleachers for the same amount of time.
lbvjy [14]

Answer:

The correct answer would be Jenna’s cells are producing more lactic acid than Raul’s cells.

Workouts like sprints, bleachers, weight training et cetera come under the anaerobic zone of training.

They cause lack of oxygen in the muscles due to which muscles undergo lactic acid fermentation to produce energy (ATP).

Lactic acid fermentation converts one molecule of glucose into 2 molecules of lactic acid with a net gain of 2 ATP (as compared to 36-38 ATP produced in aerobic respiration).

Decreased efficiency in energy production leads to the utilization of more and more glucose or glycogen reserves of the muscles and lead to the accumulation of more and more lactic acid.

Cells in the nervous system are  different in structure from cells in the  circulatory system, and they carry out  different specialized functions is the statement which accurately compares cells in the human circulatory system to cells in the human nervous system.

Option C

<h3><u>Explanation:</u></h3>

Cells of the circulatory system includes blood corpuscles like red blood cells, white blood cells, platelets, and plasma. Cells of nervous system include neurons, neuroglia, and supplying blood vessels.  

The cells of each of the system are completely different from each other. They perform specialized functions and are totally different in shape and sizes. A neuron can be 1 meter in length as in vagus nerve. But RBCs are 7.5 micron in diameter, and a WBC is 20 micron in diameter. Platelets are even smaller. So they are structurally and functionally different.
