Cells often need to take in materials from their environment which are
found in lower concentration outside the cell compared to inside the cell.
In order to do this, cells must use energy from ATP to move these materials
against the concentration gradient through active transport.
with the concentration gradient through active transport.
against the concentration gradient through passive transport.
with the concentration gradient through passive transport.
Answer:
With the concentration gradient through passive Transport
Explanation:
I haven't taken biology recently, but if I'm not mistaken, cells that use ATP can only passively do things.
Cells often need to take in materials from their environment which are with the concentrate gradient through passive transport. So the correct option is D.
What is passive transport?A kind of cellular transport known as passive transport involves the movement of molecules and ions along concentration gradients. It indicates that a drug has a propensity to migrate from a region of higher concentration to a region of lower concentration.
When there are few substances anywhere, those substances tend to migrate there. Contrary to active transport, another kind of cellular transport, which fundamentally requires ATP to move substances against their concentration gradient, the method does not involve metabolic energy (e.g. ATP) since the chemicals are moved downwards or along their concentration gradient. The four main methods of passive transport are osmosis, filtration, simple diffusion, and assisted diffusion.
When a drug is transported passively, it is moved from an area of higher concentration to one of lower concentration. As a result, chemicals migrate along a gradient of concentration.
Therefore the correct option is D.

Three species of finches are in competition for the limited resources of an ecosystem. One species
prefers fruit to seeds. The second species prefers seeds to fruit. The third species will eat fruit or
seeds with equal preference. If the third species is removed from the area, how will the ecosystem
change?
a. Resources will be more abundant.
b. The climate of the ecosystem will change.
c. Fruit and seed resources will become less abundant.
d. Water will become more readily available.
Answer:
the answer is option a
Explanation:
The finches evolved to have different beak shapes to be able to eat the food available on the different islands.
If one species is removed then the resources will be more abundant for the other two species.
What will happen if 3rd species is removed?If the third species is removed from the area then seeds and fruits will be more available for the one and second species.
Because the third species is eating both seeds and fruits in equal preference if they are removed then these resources will be available in more abundant for the other two species.
Thus, we can conclude that the correct option is (a), Resources will be more abundant.

Answer:
Environment.
Explanation:
The respiratory system interacts with the environment by contracting and expanding the diaphragm and chest in order to do breathing. When the muscles in the diaphragm contracts and the expansion of chest occurs, takes the air inside the body that is present in the outside environment for inhalation of oxygen while on the other hand, when the diaphragm expands and chest contract, the air inside the body is removed with the removal of carbondioxide gas.

Explain why a leaf kept in the light for 24 hours will turn an iodine solution blue-black, whereas a leaf kept in light for 24 hours and then in the dark for 24 hours will have no effect on an iodine solution
Answer:
The leaf kept in the light will turn blue-black because of the presence of starch after photosynthesizing. The leaf in the dark could not photosynthesize, which would not create starch so the iodine solution will have no effect.
Explanation:
Iodine stains a blue black in the presence of starch
What type of species is most likely to lead to extinction of another species? a Invasive species b Native species c Genetically isolated species d A and B
Answer:
A
Explanation:
Like Christopher Columbus
:)
The type of species that is most likely to lead to the extinction of another species is known as Invasive species. Thus, the correct option for this question is A.
What is Species?Species may be defined as a cluster of organisms that can reproduce with one another in nature and produce fertile offspring.
Invasive species are those that are not native to a particular habitat. They just arrive there in search of resources that support them in order to survive and reproduce naturally.
These arrived species utilize the resources like food, space, etc. of the native species and make them oppressed to eliminate from this habitat.
Therefore, invasive species is the type of species that is most likely to lead to the extinction of another species. Thus, the correct option for this question is A.

What is photosynthesis
Answer:
The process of a plant converting sunlight, carbon dioxide and water into food
Explanation:
Hey there!
Photosynthesis is the reaction that converts light energy to chemical energy in sugar and carbohydrates. Humans can't eat sunlight, so we eat plants. Plants convert the energy in the sunlight into chemical energy using chlorophyll. Chlorophyll is a molecule produced by plants, algae, and cyanobacteria, which aids in the conversion of light energy into chemical bonds. It is the green pigment found in the chloroplasts of higher plants. They are a part of our ecosystem, and they are lower on the food chain.
