Answer:
through an ecosystem
Explanation:
The amount of energy at each trophic level decreases as it moves through an ecosystem. As little as 10 percent of the energy at any trophic level is transferred to the next level; the rest is lost largely through metabolic processes as heat.
You are doing research on a bacterial species, trying to determine the nature and structure of a number of intracellular inclusions. Which type of microscopy would provide the best view of these intracellular structures
Answer:
Transmission Electron Microscope.
A Transmission Electron Microscope provides the best view of the intracellular structures.
What is Transmission Electron Microscope?
Transmission electron microscopes (TEM) are microscopes that use a particle beam of electrons to visualize specimens and generate a highly-magnified image. TEMs can magnify items up to 2 million instances. with a purpose to get a better concept of simply how small that is, think about how small a cellular is.
What is a transmission electron microscope used for?The transmission electron microscope is used to view skinny specimens (tissue sections, molecules, etc) through which electrons can bypass producing a projection picture. The TEM has similarities in lots of ways to the traditional (compound) light microscope.

How might you model the relationship between a tomato plant and the hornworm caterpillar? Identify the components of the model, including inputs and outputs.
Answer:
Ok, there are multiple ways of model this, one of the ways can be:
Knowing that a hornworm can strip a tomato plant of its foliage in about two days, we can count the number of hornworms (x, the input) and find the number of plants (y, the output) that they can eat in a day.
So, if a hornworm can eat a plant in two days, then in one day the worm can eat half a plant.
Then:
y = (0.5plants/worm)*x
This says:
The number of plants eaten in one day (y) is equal to half of the number of hornworms
OF course, there are a lot of other ways to model this, for example we can use the time as a variable x, and the number of plants as y.
Knowing that a worm eats a plant in two days:
y = (0.5 plants/day)*x
Now x is the number of days, and y is the number of plants that can be eaten by a single worm

An ecosystem experiences a loss of denitrifying prokaryotes. Will this loss affect the health of the ecosystem?
OA. No, because denitrifying prokaryotes do not produce the usable form of nitrogen needed by organisms.
OB. Yes, because an excessive level of usable nitrogen could accumulate and disrupt the ecosystem's balance.
OC. No, because atmospheric nitrogen is not necessary to most organisms in an ecosystem.
D. Yes, because plants and animals will no longer have the usable form of nitrogen that they need to grow.
egion Scor
Answer:
The correct answer is option D. Yes, because plants and animals will no longer have the usable form of nitrogen that they need to grow.
egion Scor
Explanation:
Denitrifying prokaryotes are the organisms that perform the denitrification process in which nitrate is reduce to nitrogen gas in absence of the oxygen with the help of soil microbes such as denitrifying bacteria. It is a essential process that helps in the recycling of nitrogen.
Denitrification can negatively impact global warming by increasing nitrogen gas in environment and losses of nitrous oxide and reducing soil fertility and there would be loss of productivity in agriculture.
Thus, the correct answer is option D.
Which type of protein will fight disease?
insulin
O antibodies
ligaments
genes
Answer:
antibodies
Explanation:
as antibodies are the part of immune system that fight against diseases and protect our body
while insulin is enzyme which speed the chemical reaction without affecting itself it does not fight against disease
and genes are involve in the inheritance not in the immunity so
correct answer is antibodies which produce immunity
The proteins that help to fight against diseases are ANTIBODIES.
The antibodies are specific proteins of the immune system that recognize harmful particles called antigens in order to destroy them.The antigens can be localized on the surface of pathogenic harmful microorganisms (i.e., bacteria, fungi, parasites, viruses).Antibodies are secreted into the bloodstream by differentiated B cells, which are specific cells of the adaptive immune system known as plasma cells.In conclusion, the proteins that help to fight against diseases are ANTIBODIES.

Answer:
Reinforcement
Explanation:
Reinforcement can be referred to as anything that can be used to increase, enhance or strengthen a desirable behavior in a person or an organism. Reinforcement is of two types, they include positive reinforcement and negative reinforcement. Positive reinforcement has to do with adding a reward in order to enhance a desirable behavior, while negative reinforcement has to do with removing an undesirable thing in order to strengthen a desirable behavior.
From the question asked, because the presence of insects after moving the decaying logs increased the frequency at which the bears moved the decaying logs, the finding of the insects is, therefore, a reinforcement. The finding of the enhanced or strengthened the desirable behavior.
DeKwami is conducting an experiment in which he needs to use both sucrase and catalase. Which pH should he prepare to ensure that BOTH of the enzymes will show some activity?
Answer:
pH of 6.5
Explanation:
The pH favorable to an enzyme where it is most active is called optimum pH. The optimum pH of sucrase is about 6.0 while that of catalase is 7.0. Both enzymes can however still show some activity when the solution is slightly basic or slightly acidic (from it's optimum pH). Hence, getting the middle point (6+7/2 = 6.5) between the optimum pH of the two enzymes and preparing same will ensure the enzymes show some activity.

A scientist is studying the effects of growing human populations on the biodiversity that can be found in a region. Each region selected had a different population density of humans from 1 to 10 million per 10 square miles. Then in each region the number of different species that can be found was recorded. What type of variable is the dependent variable in this experiment?
Answer:
The different species
Explanation:
There are two types of variable in a scientific experiment; Dependent and Independent variable.
An Independent variable is the variable that is intentionally or expectedly altered in order to see the effect on the dependent variable.
A dependent variable is the variable that is been observed for changes as a result of the independent variable.
For example, in the relationship between age and blood pressure, age is the independent variable while blood pressure is the dependent variable.
From the question, the different human populations is the independent variable (because it is the one been intentionally altered) while the biodiversity/different species is the dependent variable (because it is been observed for changes as a result of the different human population).

When both participants in a species' interaction develop adaptations in direct response to one another, this could progress into all of the outcomes except:
Answer:
coevolution
Explanation:
Coevolution refers to the process where two or more species modify each other's evolution via natural selection. Darwin mentioned how insects and flowering plants could coevolve by reciprocal evolutionary modifications. Coevolution has firstly been associated with mutualism between species including, for example, birds and flowering plants. However, coevolution may also involve host-parasite relationships, such as associations involving parasitic organisms and their sexually reproducing hosts. Finally, there are situations where coevolution involves both parasitism and mutualism (i.e., antagonistic coevolution).
The adaptation in direct response to one another could lead to all the outcomes except : Intraspecific interaction ( option 5 )
Intraspecific InteractionIntraspecific interaction is a kind of interaction seen within same species that compete for basic necessities for survival such as food, habitat and water. It does not lead to evolutionary changes within the species, therefore they do not develop adaptations in response to the competition
Hence we can conclude that the adaptation in direct response to one another could lead to all except intraspecific interaction
