A researcher is investigating the effects of a chemical that makes thylakoid membranes permeable to hydrogen ions then the chloroplasts will generate less ATP, which is present in the second option.
What is the function of the hydrogen ions in the chloroplast?The hydrogen ion gradient is formed when an electron passes from one complex to another, resulting in a higher concentration of hydrogen ions inside the thylakoid, which forms ATP when it passes through the ATP synthase and if the membrane becomes permeable, the gradient is not formed, resulting in less ATP.
Hence, a researcher is investigating the effects of a chemical that makes thylakoid membranes permeable to hydrogen ions then the chloroplasts will generate less ATP, which is present in the second option.

What cell parts are common to all of these cells?
Use complete sentences.
Chlamydomonas
Spirogyra
Elodea
Squamous Epithelium
Answer: All cells share four common components: (1) a plasma membrane, an outer covering that separates the cell's interior from its surrounding environment; (2) cytoplasm, consisting of a jelly-like region within the cell in which other cellular components are found; (3) DNA, the genetic material of the cell; and (4). The cells of most Chlamydomonas species are more or less oval and feature a noncellulosic membrane (theca), a stigma (eyespot), and a usually cup-shaped chloroplast. Although photosynthesis occurs, nutrients also may be absorbed through the cell surface. Asexual reproduction is by zoospores. The filamentous masses come to the surface and become visible as slimy green mats. Spirogyra has a cell wall, nucleus, pyrenoid and spiral chloroplasts. This Elodea leaf cell exemplifies a typical plant cell. It has a nucleus, and a stiff cell wall which gives the cell its box-like shape. The numerous green chloroplasts allow the cell to make its own food (by photosynthesis). The central vacuole takes up most of the volume of the cell. Squamous cells tend to have horizontally flattened, nearly oval-shaped nuclei because of the thin, flattened form of the cell. Squamous epithelium is found lining surfaces such as skin or alveoli in the lung, enabling simple passive diffusion as also found in the alveolar epithelium in the lungs. brainliest?

An acid-fast staining method was performed on a bacterial smear using the dyes carbol fuchsin and methylene blue. The resulting stained slide contained only cells that appeared blue when visualized using a microscope. Which of the following could explain why only blue cells were present?
a. No acid-fast bacteria are present on the slide
b. Methylene blue was not used
c. Carbolfuchsin was not used
d. Acid-alcohol was not used
Answer: Only blue cells where present because No acid-fast bacteria are present on the slide. The correct option is A.
Explanation:
Acid fast staining method also called Ziehl-Neelsen (Zn) technique is used in the laboratory to stain samples suspected to contain Mycobacterium species. The Mycobacterium species which includes the M. tuberculosis, M. ulcerans, and M. leprae, do not stain well by the Gram technique, which is a common routine stain in the laboratory. This is because of waxy coating on its cell surface primarily due to the presence of mycolic acid.
The acid fast stain consists of:
--> A primary dye which is the carbol
fuchsin
--> A decolorizer which is the acid alcohol
--> A counter stain which is the methylene blue.
In it mechanism of action on the bacterial smear, when the primary dye is applied,the whole cell will appear red. But after decolorizing with acid alcohol, only acid fast bacteria will retain the red colour of carbol
fuchsin while the red dye from the background cells are removed. Then the counterstain (methylene blue) is applied which is picked up by non-acid-fast bacteria making the cells appear blue under the microscope.
Therefore when the bacteria smear is viewed under the microscope and only blue cells are seen, it means No acid-fast bacteria are present on the slide.

The largest endocrine gland (s) that makes 3 hormones that affect the metabolism is the: *
A. pituitary gland
B. thyroid gland
C. pancreas
D. adrenal gland
Answer:
The largest endocrine gland (s) that makes 3 hormones that affect the metabolism is the: thyroid gland.
The largest endocrine gland that makes three hormones that affect metabolism is the Pancreas. Thus, the correct option for this question is C.
What do you mean by Endocrine Gland?An endocrine gland may be defined as a type of gland which consists of several organs that make hormones and release them directly into the blood so they can travel to tissues and organs all over the body. These hormones control many important functions in the body, including growth and development, metabolism, and reproduction.
The pancreas is the largest endocrine gland that significantly makes three hormones namely, Insulin, Glucagon, and Somatostatin. These hormones are actively involved in the regulation of metabolism by numerous mechanisms.
For example, insulin lowers the level of sugar in the blood, while glucagon increases the level of sugar by transforming its storage form.
Therefore, the largest endocrine gland that makes three hormones that affect metabolism is the Pancreas. Thus, the correct option for this question is C.
