Answer:
ACTIVE TRANSPORT
Explanation:
Generally, the transport of molecules across membranes can either be ACTIVE OR PASSIVE. Active transport are those transport that occurs against a concentration gradient i.e. from an area of low concentration of the substance to an area of high concentration, hence, will require energy input in form of ATP.
On the other hand, passive transport occurs down a concentration gradient and hence do not require energy to take place. Hence, based on the description above, when a cell uses ATP energy to transport a substance through a cell membrane from an area of lower concentration to an area of higher concentration, the cell is using ACTIVE TRANSPORT.

When land is cleared for agriculture or home construction, small isolated sections of the original habitat may remain. Explain how this reduction in habitat size and the isolation of small sections of habitat might lead to species endangerment.
Answer:
Species get endangered by the process of habitat fragmentation.
Explanation:
When the land is created for cultivation and home construction this represents land-use change and the destruction of the original habitat of diverse species thereby creating a reduction in size and isolation this is known as habitat fragmentation. That is the emergence of discontinuities that causes population fragmentation and ecosystem decay. This leads to species endangerment.A habitat is:
A Interactions between species
B Resources in an ecosystem
C Where a species lives
D Nonliving things
Answer:
where species lives like water are the natural habitat of fish
David tests a small amount of new drug developed at a laboratory to make sure it meets the Food and Drug Administration standards. What is most likely David's occupation?
Answer:
Quality Control
Explanation:
The most likely occupation of David would be quality control.
The quality control unit is a section of a company that ensures that products or services produced by the company meet some specific standards as required by authorities. Quality control officers randomly test produced batches of goods to ensure that the required standards are met.
In the illustration, the body overseeing the standards of drugs is the Food and Drug Administration and the work of David is to ensure that the drugs produced meet the required standards set by the body. He is a quality control officer.

At this time in the earth's history, scientists and others are very concerned about climate change. What is the best explanation for the earth's changing climate?
Answer:
Rise of population and over-consumption resources are key factors of climate change.
Explanation:
The fact that climate change is real and is happening at a very fast rate. The impacts of which can be seen in terms of the increase in sea levels. The rise in global average mean temperatures, an increase in the melting of Greenland and Antarctic glaciers. The exposure of barren land beneath the antarctic continent. Therefore the scientific community s very concerned about the massive depletion of resources and the exposure of the earth's surface to solar radiation.The amount of energy the producers in an energy pyramid provide the primary consumers is

describe the effect of magnesium deficiency on the transport of sucrose out of the leaves and the sucrose concentration out of the leaf
Answer:
The impact of diminishing the convergence of magnesium salt on the development of S.polyrhiza is because the low mg accessibility keeps an eye on troublesome sucrose exportation, making leaves hold sucrose three to multiple times more than the leaves of plants that get Mg in satisfactory inventory, showing that the inadequacy of this supplement causes extreme hindrance of sucrose transport.

how can we control water pollution?
Answer:
How we can control water pollution is by picking up litter or picking up any type of trash you see and throw it away where it is suppose to go. Another way we can control water pollution is by like planting trees, reduce th amount of plastic you use, and not pouring harsh chemicals in the drain.
What happens during fertilization that makes the offspring unique compared to the original cells?
Please write the answer in one sentence!
Answer:
During fertilization, two gametes from the parents —with different genetic information— join together to obtain a unique offspring, different from the parental cells that gave rise to it.
Explanation:
Gametes are the cells produced by each individual to transmit their genetic information to their offspring.
The process of producing gametes is called gametogenesis, and it is a reductive division called meisois. During meiotic division, crossing over occurs, allowing the recombination of genes, which results in genetic variability.
What makes the offspring different and unique from the parental generation is that, during fertilization, the genetic characteristics of both parents are mixed when two gametes are joined.

Explanation:
Would a greater or less amount of exposed surface area absorb thermal energy faster? Why? Give an example.
Answer:
Explanation:
A greater amount of surface area exposed will absorb thermal energy faster compared to a surface with a lesser exposed area.
Thermal energy is a form of kinetic energy in which the molecules of a medium increases their velocity.
In a large area with high surface are exposed, the molecules are spread out openly without obstructing each other. This will enable a faster thermal conduction through a system. A small exposed surface area inhibits thermal conduction. Solar panels are designed to expose more surface area to abstract more thermal energy.
Which of the following is the dependent variable in the experiment?
It is something on which other elements depend. A test score, for instance, may be a dependent variable because it could vary based on a number of variables, including how much you studied. How much sleep you got the night before the test, and even how hungry you were.
What dependent variable in the experiment?The thing being measured in an experiment or assessed in a mathematical equation is the dependent variable. The term “the result variable” is sometimes used to describe the dependent variable.
Reliant Variable the measurable variable that is dependent on other measurable things. As a result of manipulating the independent variable or variables in an experiment, these variables should change.
Therefore, In an investigation, the result is a dependent variable whose value is affected by changes in the independent variable.

Explain Lamarck's ideas about how organisms changed over time.
Answer:
Lamarckism, a theory of evolution based on the principle that physical changes in organisms during their lifetime—such as greater development of an organ or a part through increased use—could be transmitted to their offspring.Body structures can change according to the actions of the organism.have an innate tendency toward complexity and perfection. The actions of organisms as they use or fail to use body structures.
Lamarck claimed that organisms changed how they behaved in response to environmental change. Their altered behavior caused their organs to undergo modification, which their progeny inherited.
What are the main points of Lamarck's theory of evolution?Lamarck asserts that when the environment changes, animals develop new demands (besoins). This results in novel behaviors that make use of already-existing organs.
Darwin proposed hypotheses like inheritance, different survival, species variety, and extinction, whereas Lamarck proposed theories like the inheritance of acquired features, use and disuse, growth in complexity.
According to Lamarck's theory of evolution, an organism's traits that evolve over the course of its existence in reaction to its environment are inherited by or passed on to its children.
