Many key ecosystem services provided by biodiversity, such as nutrient cycling, carbon sequestration, pest regulation and pollination, sustain agricultural productivity. Promoting the healthy functioning of ecosystems ensures the resilience of agriculture as it intensifies to meet growing demands for food production.
It is flu season! The flu is caused by a virus. Scientists continue to debate whether or not viruses are alive. If we consider the image of the flu virus seen here, we could say that a virus is NOT alive because https://www.usatestprep.com/modules/gallery/file.php?id=1531 for the picture
Answer: the answer is D
Explanation:
Answer: There is no cellular structure
Explanation: If we use the image to support our argument, we could say a virus s not living because there is no cellular structure. All prokaryotic cells lack a nucleus. We cannot tell, from the image, anything about its way of life.
Please help, This is a science sheet for get my grade up.
Answer:
Well The answer you choose was wrong I think because every living being that has cells need a Nulceus in their cells or the cells won’t work. Fungi have cells and Protista also have a nucleus since it has a cell or cells.
The answer here I would think would be (c) ”many could be found in fresh water”. Fungi don’t usually appear near seas or fresh sources which in this case is a pond and protistia do.

In the early 1900s, three species of goatsbeard wildflowers, T. dubius, T pratensis, and T. porrifolius, were introduced to the United States. Each of the species had a chromosome number of 2N. In the 1930’s, a few populations of offspring from the original wildflowers were identified as having a chromosome number 4N. What does this data suggest about speciation.
A. Speciation has occurred because the original species of wildflowers produced populations of viable offspring.
B. Speciation has occurred because breeding between the offspring and original populations would not be possible.
C. Speciation has not occurred because the offspring of the original wildflowers were not introduced into a new area.
D. Speciation has not occurred because the offspring inherited identical genetic information to the original wildflowers.
Answer:
B. Speciation has occurred because breeding between the offspring and original populations would not be possible.
Explanation:
Speciation has occurred in the species due to no breeding between the offspring and original populations because the offspring and original species has different number of chromosomes in their DNA. Due to this difference in the chromosome number in the DNA, there is no chance of breeding between offspring and original species. Speciation is the evolutionary process by which populations of organism evolve with the passage of time and become different from the original species.
What do the NADPH and ATP do in the Calvin cycle?
Answer:
ATP and NADPH produced by the light reactions are used in the Calvin cycle to reduce carbon dioxide to sugar. ATP is the energy source, while NADPH is the reducing agent that adds high-energy electrons to form sugar.

Hello, jamesundercover06.
The first box, starting on the left, I believe, should be H2O. The second box, the one over the arrow, should be sunlight. The third box, right after the arrow, should be C6H12O6. The final box, then, should be O2. I'm pretty sure that this is right, but if it is incorrect in any way let me know and I will do my best to give you the correct answer.
PS. Brainliest would be appreciated. :)
Male organisms will commonly engage in physical activity to show dominance during mating season. Male kangaroos can commonly be observed kicking one another, while bighorn rams will gather and crash their heads/rams into each other prior to mating season. This is an example of ______.
Question options:
competition
predation
commensalism
parasitism
Male kangaroos that kick one another and bighorn rams will gather and crash their heads into each other prior to mating season are examples of competition.
What is competition?Competition is a type of ecological relationship in which two organisms contend for the same resource (e.g., food).
Competition can be divided into intraspecific competition and interspecific competition.In general, intraspecific competition makes reference to competence for reproduction.In conclusion, male kangaroos that kick one another and bighorn rams will gather and crash their heads into each other prior to mating season are examples of competition.

Mutations within a DNA sequence are natural processes that--
A are usually good.
B are usually bad.
C usually cause cancer.
D produce genetic diversity.
Answer:
D
Explanation:
Mutations can cause other species to occur, like polar bears. They also cause different genetic traits within a species like different hair color.
Answer:
d
Explanation:

Two interacting systems involved in plant transport are shown here. Which statement best describes the function of xylem and phloem in transporting substances throughout the plant?
Answer:
C. Xylem transport water and nutrients from the soil to the leaves while phloem transport carbohydrates from the leaves to the rest of the plant.
Explanation:
In many tropical rainforests, people clear land by cutting down trees and burning them. After a few years, the soil runs out of nutrients and cannot be farmed any longer. How does this affect Earth's atmosphere?
Answer:
Land will convert into desert eventually
Explanation:
When the soil gets devoid of nutrient, it will be unable to support trees, plants or vegetation of any type. Trees and plants are responsible for holding the soil tightly and prevent it from eroding.
Once there will be no nutrient in soil, there will be no trees, plants or vegetation and hence there will be no mechanism to prevent soil erosion. Thus, the soil will erode due to deforestation and the land will convert into desert eventually

What might occur if the stoma were all located on the top of the leaves?
Answer:
It depends on the plant and its environment. In a mesic terrestrial environment, the plant wouldn’t be optimized. Natural selection would then come into play and there would be an evolutionary trend towards stomata located on the lower leaf surface.
In the case of water lily, the lower epidermis is in contact of the water, and stomata are restricted to the upper surface of the leaf. This is an optimal solution for the plant. Natural selection will work to conserve that arrangement. In this case, stomata on the lower surface would exist at a water-air interface, and the diffusion of gasses across that interface would be glacially slow. Further, the stomata on the lower surface would present an opening where pathogens can enter the leaf.

Explanation:
Which term describes resistance to change in motion?
A. acceleration
B. inertia
C. net force
D. velocity
Answer:
Newton's second law of motion states that the accelaration of an object is directly proprotional to the force acting upon it. In symbols, we can write this as
[tex]F= ma[/tex]
Wher F is the force acting upon the object, m is the object's mass, and a is the object's acceleration. We can multiply both sides of this equation by 1/m to get the equivalent equation
[tex]\frac{1}{m} F= a[/tex]
What happens when we make m higher and higher? Well, that fraction 1/m gets closer and closer to zero. The same force accelarates the object less and less as that object becomes more massive. This consequence of Newton's second law, the resistance of massive objects to changes in acceleration, is called inertia, and it's one of the main expressions of mass in classical mechanics.
Answer:
acceleration
