Answer:
Mitochondria are small structures that make energy in almost all of your cells. They do it by combining oxygen with fuel molecules (sugars and fats) that come from food. When mitochondria are faulty, cells don't have enough energy.Explanation:

Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Explanation:
what are the small pores called where carbon dioxide come in
Answer:
Stomata
Explanation:
These are the small pores in plant stems or leaves that allow carbon dioxide in and oxygen and water vapor out. Each tiny hole is surrounded by a pair of cells called guard cells. These cells control whether a stoma is open or closed.

Plants using the CAM pathway occur in many locations but are most common in very arid locations, such as deserts. What deserts occur in North America and where are these deserts located?
The desert that occurs in North America is the Great Basin Desert and it is located at Nevada of North America.
CAM pathway, which is also called Crassulacean Acid Metabolism, is a pathway that involves carbon fixation that occurs in plants growing in arid areas.
With this pathway these plants are able to photosynthesize during the day, but only exchange gases at night.
An arid habitat is an environment that is characterized by extreme lack of water, example is the desert.
In North America, the desert that occurs there is the Great Basin Desert. It spreads into different states which include:
NevadaWestern Utah, Eastern California, andIdaho.But the major part of Nevada is occupied by the Great Basin Desert.

Which of the following includes organisms that can use energy from the sun to make food?
Answer:
Explanation:
An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers. Plants are the most familiar type of autotroph, but there are many different kinds of autotrophic organisms.
When was a control used in the investigation of the amphipods and sea butterflies? Why was a control necessary?
pteropods or sea snails, also called sea angels, produce chemical deterrents to ward off predators, and some species of amphipods take advantage of this by carrying pteropods piggyback to gain protection from their voracious predators.

Maggots get their energy by breaking down dead and decaying animals. What are maggots? autotrophs producers decomposers heterotrophs.
Food is the source of energy that is used by the organism for the process of metabolism. Maggots are the larva of flies and depend on dead and decaying matters.
Maggots are:
Option C. Decomposers
This type of organism can be explained as:
The organism is classified into different classes according to the nature of its feeding habits.Autotrophs are called the primary producer and break inorganic compounds into organic for energy.Producers are the organism that produces their food by converting solar energy into chemical energy.Decomposers are small-sized organism that lives in soil and breaks the organic compound of dead and decayed bodies.Heterotrophs are organism that depends on other sources and producers for energy.Therefore, maggots are decomposers.

A rat has 42 chromosomes in eath somatic call. How many chromosomes are in each gamete
Answer:
21 chromosomes
Explanation:
Somatic cells are a diploid which have 2 sets of chromosomes. If two sets are 42 chromosomes, one set must be 21 chromosomes. Gametes are a haploid which have only 1 set of chromosomes. So in each gamete, there should be 21 chromosomes.
what would happen to the carrying capacity of the ecosystem & why
Q-a volcano covers an area with 2 feet of lava
Answer:
The carrying capacity would shoot downward.
Explanation:
The area would no-longer be able to support organisms or the ground until the lava cools off. Even after then, any plants that may have been there will be gone, meaning that the ecosystem can now support less herbivores, as well as less primary producers (plants).
Less plants, means less herbivores, which means less of the animals that eat the herbivores (secondary and tertiary consumers).

the production of alcohol by yeast cells is the result of
Answer:
Fermentation
Explanation:
Hope this helps!
The production of alcohol by yeast cells is the result of anaerobic respiration. The correct option is D).
What are anaerobic respirations?All living cells undergo respiration, a chemical activity that releases energy from glucose. Without oxygen, anaerobic respiration occurs and produces less energy but does it more quickly. Fermentation refers to anaerobic respiration in microorganisms.
When you work out vigorously, your muscles engage in anaerobic respiration. Compared to aerobic respiration, less energy is released because glucose is not completely broken down.
During intense activity, lactic acid accumulates in the muscles. Later, the lactic acid must be oxidized to produce carbon dioxide and water.
Therefore, the correct option is D) Anaerobic respiration.

The first reaction of the body to a cut is to restore the continuity ?
Explanation:
First,blood cells called platelets join together at the paper cut and form a clot to stop the bleeding.The platelets then release chemicals called Cytokines into your blood stream.Cytokines attract the attention of certain cells to start healing your cut.
When the skin injured,our body sets into motion an automatic series of events,often reffered to as the " cascade of healing",in order to repair the injured tissues.The cascade of healing is divided into four overlapping phases:Hemostasis,Inflammatory,Poliferative,and Maturation.
That's the answer Hope it helps
