Biology
1 answer:
Daniel [21]3 years ago
5 0

Answer:

Temperature is usually uniform throughout a cell (Ans. C)

Explanation:

Heat or thermal energy is a kinetic energy. That is connected with the random movements present in the atoms. Temperature is usually uniform throughout the cell so the most cell can not harness heat to perform work.

Heat is a type of energy which is transfer from one body to another body due to the temperature difference.

It can only perform work if it is transferred from one source which is warmer to a body which is cooler. The temperature in living organisms is usually kept very constant due to the process of homeostasis.

Which causes genetic recombination?
labwork [276]

Answer:

Recombination occurs when two molecules of DNA exchange pieces of their genetic material with each other. One of the most notable examples of recombination takes place during meiosis (specifically, during prophase I), when homologous chromosomes line up in pairs and swap segments of DNA.

Build a word that means ketone bodies (acids and acetones) in the blood: ____________________.
tangare [24]

Ketogenesis is the process where organism produces ketones in the body.

Ketogenesis is a metabolic pathway that produces ketone bodies, which provide an alternative form of energy for the body. The body is constantly producing small amounts of ketone bodies that can make 22 ATP each in normal circumstances, and it is regulated mainly by insulin.

Ketosis happens when your carbohydrate intake is low. As your body breaks down fat, it produces an acid called ketones or ketone bodies, which becomes your body and brain's main source of energy. Ketogenesis occurs primarily in the mitochondria of liver cells. Fatty acids are brought into the mitochondria via carnitine palmitoyl transferase (CPT-1) and then broken down into acetyl CoA via beta-oxidation.

The _______________ community has low diversity with microorganisms primarily in the Leptospirillum groups II and III and from t
ExtremeBDS [4]

Answer:

The <u>Acidophilic Microbial</u> Community has low diversity with microorganisms primarily in Leptospirillum groups II and III and from Ferroplasma types I and II.

Explanation:

An acidophilic microorganism or plant is one which grows best in acidic conditions.

They are also referred to as microorganisms which occur in acidic natural (solfataric fields, sulphuric pools) and man-made (eg. Acid mine drainage) environments.

Acidophilic Microbes otherwise known as Acidophiles are an ecologically and economically important group.

They possess networked cellular adaptations for regulating intracellular pH. Several extracellular enzymes from acidophilic microbes are known to be functional at much lower pH than that inside the cells.

Acid stable enzymes have applications in several industries such as starch, baking, fruit juice processing, animal feed and pharmaceuticals, and some of them have already been commercialized. Acidophiles are widely used in bio-leaching of metals from low grade ores

Recent studies show that acidophiles are currently being considered to be utilized in bio-conversion and bio-remediation, as well as in microbial fuel cells to generate electricity.

Acidophilic microbes of similar characteristics are classifed in groups for ease of study and identification.

Leptospirillum Group II and II as well as Ferroplasma types I and II are groups of acidophilic microorganisms within the Acidophillic Microbial community.

Cheers!

Is this true? "Individuals with an increased pigmentation, survive and reproduce more near the equator."
MAVERICK [17]
Yes. The darker pigmentation of their skin helps them survive in the sun. Therefore they will thrive more so then someone with fair skin. Darker and lighter pigment in skin, is an adaptation humans went through based mostly on the amount of sun. If you lived in the heat with a lot of sun exposure ex: Africa, you would need to have darker skin to keep from being sun burnt as badly. Someone far from the equator with less sun or: Russia, wouldn’t need as much pigmentation in their skin for this reason. Heat also plays a role in it I believe.
