All life depends on the availability of usable energy. This energy is released when
kiruha [24]

Answer:

3 (Cells carry out the respiration process)

Explanation:

Cellular respiration is a metabolic (catabolic) process common to all living things as all living things need energy for their life processes.

Respiration is the biochemical process in which the cells of an organism obtain energy by breaking down organic molecules in presence or absence of oxygen (aerobic or anaerobic) resulting in the release of Carbondioxide (CO2), water and Adenosine triphosphate (ATP).

Food molecules (containing stored energy in their chemical bonds) absorbed after digestion are broken down and the energy within their molecules are freed. This freed energy in form of ATP, is used to power the organism's movement and physiological functions.

Note that, ATP is an energy carrying molecule and a usable form of energy by cells. This is so because ATP releases energy quickly. Energy is released from ATP when the end phosphate (Pi) is removed to become ADP (adenosine diphosphate), which is a low energy molecule.

Aerobic cellular respiration consists of Glycolysis, Kreb's cycle and Oxidative phosphorylation. A total of 38 ATP molecules is produced in the cytosol of prokaryotes while a total of 36 ATP molecules is produced in the mitochondria of eukaryotic cells.

Henrietta is in the fifth week of her pregnancy, which means that she is in the _____ period of prenatal development.
Talja [164]

Answer:

Embryonic period

Explanation:

The time period of the growth of the baby in the womb of the mother of human is 38 weeks or 9 months.

The time period of 38 weeks is divided into three phases related to the events taking place in that period which are: the germinal period, embryonic period and the fetal period.

  • The germinal period lasts from the implantation to the gastrula phase during which the germ layer begins to form that is in the first and second week.
  • The embryonic phase begins after the second week and lasts about the eighth week which is marked by the phase of embryonic and differentiation.

Therefore, in the fifth week she is in the embryonic phase of prenatal development.
