Answer: While active transport requires energy and work, passive transport does not. There are several different types of this easy movement of molecules.
Explanation:
Answer:
Passive transport.
Explanation:
Osmosis and diffusion because a single substance tends to move from an area of high concentration to an area of low concentration until the concentration is equal across the space. Osmosis is a passive transport process during which water moves from areas where solutes are less concentrated to areas where they are more concentrated.
Studying which of the following would provide the best evidence that two organisms share a common ancestor?
A: Amino acid sequence
B: Dietary preferences
C: Habitat requirements
D: Social group interactions
Answer:
A
Explanation:
Studying amino acid sequences would provide the best evidence that two organisms share a common ancestor.
Amino acid sequence is a series of bases with different letters usually four(A T C G or U) this letter contains information of an individual when translated.
The amino acid sequence of 2 or more individuals can be compare to each other through the process called Blasting using a tool called Blast
Blast generates alignments or similarities between a amino acid or protein sequence.For organisms that are phylogenetically close i.e related by an ancestor, there will be similarities between their DNA sequences when compared. The amino acid sequence of an individual contains the information of the individual and it is unique for each individual.
Hence, amino acids sequence provides the best evidence of organisms sharing a common ancestor.

Which of the following is not a technological way of improving air quality?
a.
using electrostatic precipitators
b.
installing solar panels
c.
composting
d.
building wind turbines
Answer:
c.
composting
Explanation:
Composting is not a technological way of improving air quality (Option C).
What is air quality?Air quality refers to the absence of pollutant substances (e.g. monoxide carbon) in the air.
Air quality is fundamental for maintaining overall health and increasing the quality of life.Air quality can be measured by using different devices or indicators (for example, by measuring the amount of carbon monoxide and nitrogen oxides).In conclusion, composting is not a technological way of improving air quality (Option C).

what is the difference between sexual and asexual reproduction for plants and animals?
Answer:
That is the main difference between sexual and asexual reproduction. Sexual reproduction just means combining genetic material from two parents. Asexual reproduction produces offspring genetically identical to the one parent.
A 100 kg box is initially at rest on a level surface. One 10 N force acts on the box , directed toward the right. A second 10 N force acts simultaneously on the box , directed toward the left , as shown.
Since 10 N forces are acting from both sides, these are balanced forces and the box will not move because balanced forces are acting on it. So the correct option is D.
What are balanced forces?Forces that are equal in magnitude and opposing in direction are said to be balanced forces. Equilibrium is seen as a condition of balanced forces. There is no shift in direction when the forces are in balance.
Balanced combined forces have always been equal to zero. These are vectors for merging. Balance forces cannot alter an object's momentum or direction.
An item is kept traveling at a constant speed by a balanced force. In it, Newton's First Law of Motion is explained. A good illustration of a balanced force is a book on the table. The normal force (support force) of the table balances out the weight of the book. The two forces are exactly equal and opposed to one another.
While forces that are balanced can keep an item at rest or move at a steady speed, unequal forces can cause things to accelerate.
Therefore the correct option is D.

A human liver cell has a different size and shape from a human muscle cell. What is the best explanation for these differences?
A. The cells perform different functions.
OB. One of the cells is used to reproduce more cells while the other is not.
OC. One type of cell develops into the other type of cell.
OD. One of the cells must have come from another species.
Answer:
A
Explanation:
A human liver cell would have a different size and shape from a human muscle cell because they perform different functions in the body.
The shape a cell would assume and its size depends on the function the cell performs. The functions of the liver in the body of humans differ greatly from the functions of muscles. While the former helps in detoxification, deamination, digestion, etc., the latter helps in support, movement, etc.
The correct option is A.
A human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.
CELL:
Cell is the basic and fundamental unit of life. It is the simplest level of organization of an organism. Cells contain organelles that help them perform specific functions. Organs are made up of numerous cells. Similar cells perform similar functions while dissimilar cells perform dissimilar functions. Therefore, a human liver cell has a different size and shape from a human muscle cell because the cells perform different functions.Learn more at: https://brainly.com/question/22663686?referrer=searchResults
How the nervous and endocrine systems maintain homeostasis?
Answer:
Hope this helps :D
Explanation:
Homeostasis is the process of how you have a controlled body temperature.
The nervous system detects that your body temperature is falling (or rising) so the endocrine system send the chemical messengers (hormones) to bring the body temperature back to normal.
Cells reproduce by splitting in half a process called cell division what do you cells need between divisions to make sure that they don’t get smaller and smaller
