Answer:
vacuoles – transport
cell wall – protect
nucleus – control
Explanation:
Vacuole is a small sac containing fluid and helps in the transport of substances within and outside the cell
Cell wall is external to the cell membrane and serves a structural function helping the cell maintain its shape and PROTECTING the cell from damage.
Nucleus is an organelle found in cells of plants and animals. It contains genetic information in DNA or RNA, and CONTROLS the entire life process
Note that mitochondria helps to provide ENERGY to build up substances in the cell NOT DECOMPOSE
Answer:
The correct answer is paired sample t-test.
Explanation:
Based on the given information, the mothers living in poverty in the United States give birth to underweight babies. The average weight of the babies given birth by women living in poverty is 2.8 kg. To examine the efficacy of a novel prenatal care program, a test was conducted by the CDC in which 30 mothers living in poverty and the weights of their babies were recorded.
As the test is conducted in pairs, thus, paired sample t-test would be the appropriate hypothesis test. The paired t-test is performed when the dependent variable is measure spontaneously. In the given case, the women participating in the program and the number of babies with less birth weight are examined in pairs. Thus, as the sample are paired together, the correct answer would be paired sample t-test.
The answer would be: <span>addison's disease
Cortisol is produced by the adrenal glands that located above the kidney. </span>Addison's disease appears w<span>hen the adrenal glands produce less cortisol than needed. The cause might be autoimmune cells attacking the glands or infection of tuberculosis. Cortisol deficiency could be fatal in some cases, called adrenal crisis.

Answer:
The correct answer is (C) Reabsorption is the movement of molecules in the nephron back into the capillaries
Explanation:
Reabsorption is the transfer of water and solutes molecules from the tubules of the nephron to the capillaries surrounding the tubules. This reabsorption is necessary to maintain the osmotic balance and volume of blood in the body.
Most of the reabsorp[tion take place in the PCT region of the nephron. Almost 100% of glucose is reabsorbed here. Reabsorption of water, ions, hormone, vitamins, urea, etc also takes place here. Reabsorption of some molecule also takes place in Henle loop, DCT, and collective duct.
Therefore the correct answer is c.
