a) make new cells, and only germ-line cells do it;
b) make eggs or sperm, and all the body cells do it make eggs or sperm, and only germ-line cells do it;
c) make new cells, and all body cells do it make eggs or sperm, and only somatic cells do it;
d) make new cells, and all body cells do it make new cells, and all body cells do it;
e) make eggs or sperm, and only germ-line cells do it
Answers
Answer:
A) make new cells(somatic cells)and only germ-line cells do it(meiosis)
Explanation:
Meiosis is the process through which germ cells that produce gametes such as sperm and eggs are formed. It is an equatorial division that involves the parental cell dividing into daughter cells each containing similar genetic material as the parents cell and this can be passed on to successive generation.
While Somatic cells are cells that form the building blocks of the body, they are the actively divided body part and only divide by mitosis.
Meiosis produces germ cells while mitosis produces somatic cells.
why do oxygen gas and hydrogen gas have different properties?
Answers
☁️ Answer ☁️
Furthermore, another difference between hydrogen and oxygen is that the hydrogen gas is highly flammable while oxygen gas is non-flammable. But, oxygen gas aids the combustion of other materials. Aboveall, the key difference between hydrogen and oxygen is that the hydrogen is a very light gas whereas the oxygen is a heavy gas.

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
Answers
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.

Which type of macromolecules helps a cell brake down food? Lipids proteins carbonhydrates or nucliec acids
Answers
Answer:
Proteins
Explanation:
There are four major biomolecules found in living system namely; proteins, carbohydrates, lipids and nucleic acids. These biomolecules serve different and unique functions in the body. PROTEIN is a biomolecule that helps in the break down of food substances in the body as stated in this question.
Specifically, these function of breaking down food substances is carried out by ENZYMES, which are biological catalysts that are proteinous in nature i.e. structurally made of proteins. For example, amylase enzyme breaks down starch, lipases break down lipids. Hence, since enzymes that perform this disintegration function are PROTEINOUS, then PROTEINS are the biomolecules that perform the role.

Explain how running water, groundwater, waves, and glaciers cause erosion and deposition.
Answers
Answer:
Water flowing over Earth's surface or underground causes erosion and deposition. Water flowing over a steeper slope moves faster and causes more erosion. Erosion and deposition by slow-flowing rivers create broad floodplains and meanders. Deposition by streams and rivers may form alluvial fans and deltas.

Scientists build models based on what they know from previous research to derive testable hypotheses. Independently, both Watson and Crick and their competitor Linus Pauling constructed an incorrect triple helix model with the nitrogenous bases arranged so they were on the exterior of the molecule and the phosphate groups on the interior. Although their model was wrong, what assumption made it reasonable to build a model with the bases projecting to the outside
Answers
Answer:
Nitrogenous bases contain the genetic information, their amount is variable among different species, and the arrangement of these bases is also variable among different species
Explanation:
Both Watson-Crick and Pauling's DNA models considered that DNA nitrogenous bases (i.e., Adenine, Cytosine, Thymine and Guanine) contain the genetic information that determines the characteristics of living organisms. Moreover, both DNA models also considered that nitrogenous base composition varies between species, as well as the arrangement of these bases in the DNA chain also varies between species. Based on these features, Linus Pauling considered that a model where nitrogenous bases would be arranged on the outside of the DNA molecule would be easier for the DNA molecule to be replicated, transcribed, or repaired. Although incorrect, Pauling's DNA triple helix model was fundamental to develop the helical (double-stranded) structure of DNA, which was finally discovered by Watson and Crick in 1953.
