The correct answer is option B

Dependent variable can be defined as the result of the experiment which is being measured.The dependent variable responds to the independent variable.

The result of sleeping for 8 and the result of sleeping for 5 hours will be different.

Here option b states the result of the experiment so the dependent variable will be the result of memory tests for both the groups.

Explain how dysfunction at one level of organization impacts other levels and provide an example.
Nuetrik [128]

Answer:

Please find the explanation below

Explanation:

All living organisms are made up of four level of organizations namely: cell, tissue, organs, organ system and ultimately, the organism. These levels of organization are interrelated in such a way that CELLS accumulate to form TISSUE, TISSUES accumulate to form ORGAN, ORGANS accumulate to form ORGAN SYSTEM.

Since one level is dependent on a lower level, a dysfunction in one level will cause the dysfunction of another level. For example, a dysfunction in LIVER CELLS will cause the LIVER TISSUES formed from the cells to be dysfunctional. This dysfunctionality will extend to the LIVER as an organ and cause issues in the EXCRETORY SYSTEM (an organ system that constitutes the liver organ).

How is ATP created in photosynthesis?
uranmaximum [27]

Answer:

The correct answer is option e, that is, a, b and c.  

Explanation:

The phenomenon by which green plants and other species converts light energy into chemical energy is termed as photosynthesis. During photosynthesis, the energy of the light is captivated and is utilized to transform carbon dioxide, water, and minerals into oxygen and energy-rich organic components.  

With the transport of electron through the chloroplast membrane, the energy of the electron causes the diffusion of a hydrogen ion from stroma into the thylakoid lumen, which further leads to a formation of hydrogen ion concentration gradient. This gradient ultimately results in the formation of ATP.

Describe the changes that take place during the menstrual cycle from Day 5-13 to the following:
erastovalidia [21]

Answer:

Between days 5 and 13 of a woman's menstrual cycle, an unfertilized egg in ovary prepares its development and maturation within the follicle, while the lining of the uterus -the endometrium- progressively enlarges.

Explanation:

Under normal conditions, a woman's menstrual cycle lasts 28 to 30 days, during which time both hormonal and physiological changes occur as part of the reproductive process.

Menstruation occurs as a result of the shedding of the endometrium, which had previously developed to facilitate the implantation of a possible pregnancy. This phase usually lasts five days and is characterized by genital bleeding.

From the fifth to the 13th day, a woman's reproductive system undergoes changes in preparation for possible fertilization and pregnancy:

  • <em>The unfertilized egg</em><em> is found inside the ovarian follicle, maturing before its imminent release, under the influence of follicle-stimulating hormone (FSH). The maturation of a few follicles occurs simultaneously, but only one will reach the necessary maturity to allow the release of the egg. </em>
  • <em>The lining of the uterus</em><em>, called the endometrium, receives signals from the hormone estradiol -produced by the mature ovarian follicle- and induces proliferation and thickening of the endometrium.</em>

Approximately on the 15th day of the menstrual cycle, the egg is released and it is the time when it can be fertilized by a sperm to produce the zygote, which will start a pregnancy in women.
