When mammals get an infection, their internal body temperature often rises 2 to 3 degrees Celsius. The body gets the energy it needs to react to an infection by -
Answer:
The correct answer is - increasing the rate of cellular respiration in the mitochondria.
Explanation:
During the infection, the body of mammals increases its temperature to kill the pathogens that normally die at high temperatures. To increase the body temperature our body promotes the rate of cellular respiration in the cells to produce more energy.
Cellular respiration is the process that helps in converting stored energy into a form of useable energy for the cell which is ATP. It takes place in the mitochondria of the cell which is called as the powerhouse of the cell and all the function related to energy or ATP is conducted by here.

The things that you will predict will eventually happen at the East African Rift Zone are the Water from the Gulf of Aden and the Indian Ocean will flow into the rift and flood the area. Thus, the correct option for this question is C.
What is plate tectonics?Tectonic plates are the types of crustal plates that are gigantic pieces of the Earth's crust and uppermost mantle. A crustal plate may be defined as a type of large block or tabular section of the lithosphere that significantly reacts to tectonic forces as a unit and moves as such.
The movement of the crustal plates creates three types of tectonic boundaries: convergent, where plates move into one another; divergent, where plates move apart; and transform, where plates move sideways in relation to each other. Due to this, the water from the Gulf of Aden and the Indian Ocean will flow into the rift and flood the area.
Therefore, the correct option for this question is C.

justify that fluorine cannot exist monoatomic from nature
Answer:
Due to incomplete outermost shell.
Explanation:
Fluorine cannot exist monoatomic in nature because of its incomplete outermost shell. This incomplete outermost shell makes Fluorine more reactive and it can only be stable if it makes bond with other atoms through sharing of electron i. e. covalent bond or by complete transfer of electron i. e. ionic bond. This bond making completes its outermost shell and the Fluorine attain stability so that's why the Fluorine cannot exists in monoatomic in nature.

Which choice gives the order of a chain of events that show cause and effect relationships that results from human activity?
A. increased carbon dioxide in the atmosphere; increased water vapor in the atmosphere; increase in severe storms; increase flooding
B. increased water vapor in the atmosphere; increase in severe storms; increased carbon dioxide in the atmosphere; increase flooding
C. increased water vapor in the atmosphere; increased carbon dioxide in the atmosphere; increase in severe storms; increase flooding
D. increased carbon dioxide in the atmosphere; increase flooding; increased water vapor in the atmosphere; increase in severe storms
Answer:
D
Explanation
carbon dioxide is enhanced by human activity as it icrease it leads to many consequences so B and C are canceled
increasing carbon dioxide does not increase the water vapor immediatly
so A is canceled
so the left answer will be D
The choice that provides the ordering of the chain of events should be option D where the carbon dioxide should be increased.
What is carbon dioxide?It should be treated as colorless and nonflammable gas at the normal temperature and the pressure. Also it comprise of one carbon atom and 2 oxygen atoms. Here it should be enhanced by the human activity due to which the flooding should be increased, water vapor is also increased also the storms too.
Therefore, the option d is correct.

Answer:
Bacteria take DNA from their environment.
Explanation:
Bacterial transformation is a process of horizontal gene transfer by which some bacteria take up foreign genetic material (naked DNA) from the environment. ...

On the image, which letter represents the enzyme?
Answer:The correct answer is B
Explanation:
I hope this helps you out!
From the image, the letter that represents the enzyme is B.
Enzymes are substances, made up of proteins, which are capable of speeding up the metabolic reactions in the human body.
There is a theory that explains the mechanism of action of enzymes. This is called the enzyme lock and key theory.
This theory states that enzymes bind to substrates temporarily forming enzyme-substrate complex that appears like the fitting of a lock and key.
This simply means that the same way a particular key can only fit into a particular lock is the same way a particular substrate must combine with a particular enzyme for a reaction to occur.
From the diagram,
B represents the enzyme with an active site which must fit into a substrate
A represents the substrate.
Therefore, the the letter that represents the enzyme is B.

Which step is meiosis is shown in the image below ?
Anaphase I of meiosis in shown in this image.
What do you mean by meiosis?Meiosis is a special type of cell division of germ cells in sexually-reproducing organisms that produces the gametes, such as sperm or egg cells.
Meiosis is a process where a single cell divides twice to produce four cells containing half the original amount of genetic information. These cells are our sex cells – sperm in males, eggs in females.
Cells divide and reproduce in two ways, mitosis and meiosis. Mitosis results in two identical daughter cells, whereas meiosis results in four sex cells. Like mitosis, meiosis also has distinct stages called prophase, metaphase, anaphase, and telophase.

Answer: All organisms need energy. ...
Autotrophs (producers) use energy directly from the sun or from chemicals to produce organic molecules. ...
Heterotrophs (consumers) obtain energy by consuming other organisms. ...
The flow of energy in an ecosystem can be represented with a food chain or food web
Explanation: A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.” Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. A consumer is an organism that eats other organisms or organic matter instead of producing its own nutrients or obtaining nutrients from inorganic sources. Consumers are also called heterotrophs, or other-feeders Producers
Producers: Producers are organisms that get their energy directly from the Sun. Their cells are able to turn sunlight into food through a process called photosynthesis. Organisms, such as humans, take in "substrates" such as glucose, in our food. During a process called respiration, we react 4these substrates with oxygen to give carbon dioxide and water; this takes place in the mitochondria of our cells.

movement of water molecules be? *
(1 Point)
a) Into the cell.
b) Out of the cell.
Answer:
a) Into the cell.
Explanation:
The water molecules outside the cell would move into the cell until there is no net movement of water molecules. This process is known as osmosis.
Osmosis is the movement of molecules from a region of higher concentration to a region of lower concentration through a semi-permeable membrane until the concentrations across the membrane are equal. That is, there is no net movement of molecules across the membrane.
