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.

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.

How is the growth of land plants proof that there is carbon in the atmosphere? How does carbon exist in the atmosphere, biosphere, and geosphere all at the same time? (Site 1 )
Plants take the CO2 from the atmosphere which is used in Calvin's cycle to synthesize organic compounds that end up building the plant. This fact can be proved by marking the atmospheric CO2 with radioactive isotopes of carbon, afterwards using a Geiger counter the plant will present radioactivity.
The carbon in the atmosphere is most commonly found in the form of CO2
it has a concentration of 0.04%.CO2 is a byproduct of aerobic respiration
or combustion, for example, C6H12O6+6O2-->6CO2+6H2O. The CO2 is then used by plants in photosynthesis as mentioned earlier.
Carbon is present in the biosphere because all life is made of carbon.
Carbon is present in the geosphere most commonly under the form of hydrocarbons like methane(CH4). The carbon present in geosphere is a result of organisms decay and metabolic byproducts. For example, methanogen bacteria synthesize methane in anaerobic conditions reducing hydrogen in the presence of CO2(CO2+4H2⇒CH4+2H2O). Carbon in the geosphere can also be found in coal that becomes diamond under extreme pressure and temperature.
Carbon element exists in various parts of the atmosphere in the form of gases such as carbon dioxide. The growth of land plants proof that there is carbon in the atmosphere as they perform photosynthesis.
What is Atmospheric carbon?The atmospheric carbon refers to the carbon dioxide which is present in the atmosphere. The main source of this carbon dioxide is respiration in animals.
There is an exchange of carbon from the atmosphere, vegetation, soils and the organic matter of the atmosphere, ocean and fossil fuels all of these are continually changing. The carbon cycle is the cycle through which carbon is exchanged among the various parts of the globe that is the biosphere, geosphere, and atmosphere of the Earth.
The growth of land plants is a proof that there is carbon present in the atmosphere because the land plants use carbon dioxide and water to grow. Carbon dioxide and water are both the gases and important part of the atmosphere, so when they are combined they usually form a liquid. This liquid is then absorbed by the plants and they use it to make their own food through photosynthesis.

Briefly describe two ways in which the Hardy-Weinberg equation can be used to get information about a population.
Answer:
The Hardy-Weinberg equation can be used to gather valuable information about a population in the following two ways:
1) Estimating allele frequencies: The Hardy-Weinberg equation allows scientists to estimate the frequency of specific alleles within a population. By comparing the observed frequencies with those predicted by the equation, researchers can determine if the population is in genetic equilibrium, meaning that the allele frequencies are stable and not evolving over time.
2) Identifying evolutionary forces: If a population deviates from the expected Hardy-Weinberg equilibrium, it suggests that one or more evolutionary forces, such as natural selection, genetic drift, gene flow, or mutation, are at play. By analyzing these deviations, scientists can gain insights into the factors influencing the genetic makeup of the population and better understand the evolutionary processes driving changes in the population's gene pool.

The nurse is observing a set of new parents to ensure that they are bonding with their newborn. What displayed behavior would indicate that the parents bonding is maladaptive?
Answer:
Neglecting the child
Explanation:
Maldatives behaviors are the behaviors that do not facilitate the parent-infant bonding, meaning that they are those behaviors that are hindering the process. And the best way of removing that is to encourage the behaviors that counter them.
The process of pointing out the responsiveness of the infant is a positive strategy for facilitating parent-infant attachment. Telling the mother that she must pay attention to her infant may be perceived as derogatory and is not
appropriate. Educating the mother in infant care is important; however, pointing out the responsiveness
of her baby is a better tool for facilitating mother-infant attachment. .
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.
