Explain in a few sentences how the carbon, nitrogen, and phosphorus overlap. How do these cycles cross paths through earths spheres?
Answer:
Explanation:Energy flow and nutrient circulation are the major functions of the ecosystem.
Energy is lost as heat forever in terms of the usefulness of the system. On the other hand, nutrients of food matter never get used up. They can be recycled again and again indefinitely.
Carbon, hydrogen, oxygen, nitrogen and phosphorus as elements and compounds makeup 97% of the mass of our bodies and are more than 95% of the mass of all living organisms.
In addition to these, about 15 to 25 other elements are needed in some form for the survival and good health of plants and animals.
These elements or mineral nutrients are always in circulation moving from non-living to living and then back to the non-living components of the ecosystem in a more or less circular fashion.
This circular fashion is known as biogeochemical cycling (bio for living; geo for atmosphere).
Among the most important nutrient cycles are the carbon nutrient cycle and the nitrogen nutrient cycle.
There are many other nutrient cycles that are important in ecology, including a large number of trace mineral nutrient cycles.
Under ideal laboratory conditions the rate of growth of bacteria is proportional to the size of the population at time tt. Suppose that 21002100 bacteria are present initially and that 42004200 are present 1 hour later. How many bacteria are there at the end of 55 hours?
Answer:
The amount of bacteria that are there at the end of 55 hours is 2310231000
Explanation:
From the description in the question, the bacteria's population size doubles per hour;
Within 1 hour = 21002100 × 2 = 42004200
Thus
After 1 hr ⇒ 42004200
55 hrs ⇒ ?
? = 55 × 42004200 = 2310231000
The amount of bacteria that are there at the end of 55 hours is 2310231000

Discuss how a pathogen causes an infection. Include definitions for primary pathogen, opportunistic pathogen, infection, disease (caused by a living organism), and various stages of pathogenesis. You can choose a specific organism to describe
Answer:
Infections are generated by pathogens, pathogens that generate a rare invasion triggering an extremely risky condition for the host, opportunistic infections are usually caused by highly pathogenic microorganisms with high resistance mechanisms and are really serious signs and symptoms.
Primary pathogen is one that colonizes in a primary way by forming a biofilm or a microbiological ecosystem.
The great difference between infection and infectious disease is that the infection is the presence of microorganisms that cooperate and live with the host without generating pathology, whereas infectious disease is when these microorganisms generate a pathology or condition in the host.
Explanation:
The pathogenesis are different stages that make up the ability of a microorganism to get sick, an example is prevotella parvula or treponema denticola that during pathogenesis they quickly invade the tissues due to their movements, in addition to the tissues such as the mucosa they generate an immune distraction that release toxins in different areas to the invasion.
These are pathogenicity mechanisms, that is, how the microorganism does to be able to invade the tissues in the most oppressive way.

While there is only one species of Galapagos Island tortoise, there are several subspecies. Larger islands with more wet highlands have lush vegetation near the ground. Tortoises there tend to have high-domed shells and shorter necks, which restrict upward head movement. They also have shorter limbs. They are the heaviest and largest of the subspecies. Smaller drier islands are inhabited by tortoises with longer necks and limbs and with shells that are elevated above the neck, which allow them to browse taller vegetation. Based on the information given, which is a plausible explanation for the ancestry of the tortoise subspecies?
Answer:
Tortoises with better adaptations in shell shape and leg length were selected to exploit the food resources on each island and, thus, they were capable of having more offspring.
Explanation:
Natural selection can be defined as the process of differential survival and reproduction in a given environment due to differences in their phenotypic traits. Thus, these phenotypic traits are selected to be better adapted to their environment. As a consequence of natural selection, organisms evolve by changing their phenotype frequencies over many generations. In this case, phenotypic differences are expressed as variations in shell shape and leg length, which are adaptive traits that were selected on each island.
Answer: D. Individuals with different adaptations in shell shape and leg length best exploited the food resource and left more surviving offspring in each island.

Where does the food that animals and people eat come from?
The food that animals and people eat comes from a variety of sources, including plants, animals, and other organisms, as plants are the primary source of food for most animals, including humans.
What is food for animals?They use photosynthesis to produce carbohydrates, proteins, and fats, which form the basis of their tissues. These nutrients are stored in different parts of the plant, such as the leaves, fruits, seeds, and roots, and can be harvested for human consumption. Animals also provide food for humans and other animals. Meat, dairy products, and eggs are some examples of animal-derived foods. Animals obtain their nutrients by consuming plants or other animals, and the nutrients get transferred up the food chain to other animals that feed on them.
Hence, The food that animals and people eat comes from a variety of sources, including plants, animals, and other organisms.

what makes stem cells different from cells in the body
Answer:
Stem cells are the body's raw materials
Explanation:
Stem cells are the body's raw materials — cells from which all other cells with specialized functions are generated. Under the right conditions in the body or a laboratory, stem cells divide to form more cells called daughter cells.
Stem cells are different from the other body cells as these are unspecialized cells which can undergo division and renew on their own. The stem cells can undergo specialization by the process of cellular differentiation.
What are Stem cells?Stem cells can be defined as the body's raw materials. These are the cells from which all the other cells with specialized functions are generated.
Embryonic stem cells are the pluripotent stem cells derived from the inner cell mass of a blastocyst. Blastocyst is an early-stage pre-implantation embryo. Human embryos reach the blastocyst stage in 4 to 5 days post fertilization, at which time they consist of 50 to 150 cells.
Stem cells are different from the other cells in the body in three ways which are the stem cells can divide and renew themselves over a long time. Stem cells are unspecialized cells, so they cannot do specific functions in the body unless they undergo cellular differentiation. Stem cells have the potential to become specialized cells, such as muscle cells, blood cells, and brain cells by undergoing cellular differentiation.
