Answer:
.02
Explanation:
When finding population density, divide the amount of people, animals or things in the region by the total square miles. 40/2000 is .02.
A population is the size of the group of individuals residing at a place. A population of 40 killer whales has a population density of 0.02.
What is population density?Population density is the individual's concentration of a specific species at a particular geographical location. It allows the establishment of the ecosystem and health.
Given,
Number of individulas = 40
Size of the area = 2000
Density = Number of individuals ÷ Size of the area
= 40 ÷ 2000
= 0.02
Therefore, 0.02 is the population density of killer whales.

Which of the following describes the structure of an amino acid? A. Small molecules consisting of a phosphate group, a sugar, and a nucleotide base B. A long chain of carbon atoms connected to oxygen and hydrogen atoms C. A long chain of protein molecules D. Small molecules consisting of an amino group, a carboxyl group, and a side chain
Answer:
i think option d is the answer.
The small molecules consisting of an amino group, a carboxyl group, and a side chain describes the structure of an amino acid.
What are the functions of amino acids?Amino acids are organic compounds that contain both amino and carboxylic acid functional groups. Although over 500 amino acids exist in nature, by far the most important are the alpha-amino acids, from which proteins are composed.
Amino acids function as the building blocks of proteins. Proteins catalyze the vast majority of chemical reactions that occur in the cell. They provide many of the structural elements of a cell, and they help to bind cells together into tissues.
Amino acids connect to form peptide bonds through a reaction between the amino group and the carboxyl group. The amino functional group is therefore critical to building all the proteins that makeup life on earth.

Which of the following is NOT one of the three global wind patterns?
A. Polar Easterlies
B. Westerlies
C. Trade Winds
D. Interglacial Winds
Answer:
I believe that the correct answer is d. Interglacial Winds
Explanation:
Please mark as brainiest ! Hope this helps!
Polar Easterlies, Westerlies and trade winds are the three main global wind patterns. Interglacial winds are not a type of global wind patterns. Thus, the correct option is D.
What are global wind patterns?Global Wind Patterns is mainly the result of a thermodynamic principle and the Coriolis effect due to the counterclockwise rotation of the planet earth. Warm air around the equator is lifted that creates a suction effect for air masses coming from different latitudes.
The three important global wind belts are polar easterlies, westerlies, and trade winds. The polar easterlies flow from the north and south poles towards 60° north and south, respectively. They are very cold and dry winds. The westerlies are present between 30° and 60° north and south of the Equator.
Therefore, the correct option is D.

lant cells can synthesize energy-rich organic molecules, and later break them down to extract that energy for performing life processes where does it occur?.
Answer:
Two processes were described in this question, hence, the location of the two processes are as follows:
synthesize energy-rich organic molecules- CHLOROPLAST
Break them down to extract energy- MITOCHONDRIA
Explanation:
Plant cells are unique cells capable of synthesizing their own food via a process called PHOTOSYNTHESIS. The process of photosynthesis, which occurs in an organnelle called CHLOROPLAST, synthesizes a sugar (glucose), which is an energy-rich organic molecules i.e. it stores energy in its chemical bonds.
However, to harness the usable form of energy stored in the chemical bonds of Glucose, the cells need to break down the glucose molecule. Plant cells break down glucose in a process called CELLULAR RESPIRATION in order to convert the stored energy in Glucose to a usable form called ATP. This extraction of ATP molecule needed for every life process of the plant cell is carried out in another organnelle called MITOCHONDRION.

What is the Hepatic Portal Vein?
Answer: The hepatic portal vein is one of the most important vein that receives blood from the body and transports it into the liver for filtration and processing. This vein is part of the hepatic portal system that receives all of the blood draining from the abdominal digestive tract, as well as from the pancreas, gallbladder, and spleen.
‘Hepatic’ means of or relating to the liver, therefore the hepatic portal vein is a blood vessel that sends nutrient-rich blood from the gastrointestinal tract and spleen to the liver, but also delivers toxins to the liver that will be chemically modified in the proces of detoxication
Answer:
Explanation:
hepatic portal vein is located in the upper right quadrant of the abdomen. It is typically 8 centimeters long in adults. The portal vein is responsible for carrying blood from the GI tract, gallbladder, pancreas, and spleen to the liver.The hepatic portal vein originates behind the neck of the pancreas and is usually formed by the convergence of the superior mesenteric vein and the splenic vein, referred to as the splenic-mesenteric confluence.

Answer:
c is the correct ans.
it transmits information between different parts of nervous system.
Answer:
C. It transmits information between different parts of the nervous system.
Explanation:
The nervous system has two parts, the central nervous system and the peripheral nervous system.
The central nervous system includes the brain, and the peripheral nervous system includes the spinal cord.
The spinal cord is a long, thin, tubular structure that consists of nervous tissue. The spinal cord extends between medulla oblongata in the brain to the lumbar region. It is protected by the spinal column made up of bones, called vertebrae.
One function of the spinal cord is to receive and transmit signals to the entire body and back to the brain.
The spinal cord recieves nerve impulses from the body and transmits it to the brain. It also receives orders in form of nerve impulses which are transported to receptors for response.

A wolf kills a deer that is infected with ________ of Echinococcus granulosis in its liver and eats it. After consuming the deer, the wolf's intestine becomes filled with a number of ________ produced from scoleces. These eventually release eggs into the wolf's intestines, which are released in its feces.
Answer:
The deer is infected with the parasite taenia Echinococcus granulosis, which is in the development stage of the fertile hydatid cyst. The wolf's intestine becomes filled with adult parasites, that eventually release eggs from their proglottids.Explanation: Echinococcus granulosis biological cycle.
The adult form of the parasite Echinococcus granulosis inhabits the intestines of canids, such as the dog or in the wolves, as in the exposed example. They might be 2 to 7 millimeters long, and in their anterior extreme, there is a segment known as scolex or head. The invertebrate attaches to the intestine wall by using its scolex. In the posterior extreme, there are the fertile segments of the animal, formed by three or four proglottids. The proglottides, carry the eggs and release them in the canid´s intestine. These eggs can get out of the animal´s body when it defecates. The parasite´s eggs are now in the feces of the canid.
Once on the ground or in the water, these eggs might be ingested by an intermediate host. In general, these hosts are animals such as sheep, goats, horses, pigs, and even humans. In the exposed example, the intermediate host is the deer.
The eclosion of the parasite´s eggs occurs in the thin intestine of their host, during digestion. The invertebrate penetrates the intestinal wall, from where it migrates to other organs, especially the liver and the lungs. At this point, the organism known as the oncosphere, turn into hydatid cysts. In its interior, it starts the protoscolex formation, making the size of the cyst to get bigger. When the protoscolex is completely formed, the fertile cyst is now infectious to the final host.
The final host (wolves) becomes infected when it feeds on the intermediate host. After ingestion, protoscolex gets released in the interior of the duodene. Their free state is known as scolex. At a certain point, scolex gets attached to the intestine wall where they stay until they become adults. And the cycle starts again.
