Answer:
Since diffusion moves materials from an area of higher concentration to the lower, it is described as moving solutes "down the concentration gradient." The end result of diffusion is an equal concentration, or equilibrium, of molecules on both sides of the membrane.

How does the body differentiate between potential pathogen and the body’s cells?
Answer:
A
Explanation:
The body differentiate between potential pathogen and the body’s cells by chemical markers on the outside of cells that identify them as self and non-self. Thus, option A is correct.
What precautions must be taken during the blood borne Pathogens?
The precautions that must be taken the blood borne Pathogens and Other Potentially Infectious Materials are mentioned below:
Some blood borne pathogens are hepatitis B virus, bacteria and some pathogens as well.The finger or the area must be rubbed with the alcohol and must be involved in the daily routine of the hand hygiene.The area that are exposed with the pathogens must be washed with the water and soap. The exposure source must be notified to the lab assistant or supervisor.The individual should not eat or apply anything on the wounded area exposed with the pathogens.The unprotected sex must be avoided to prevent the transmission of the pathogen from mother to the fetus.The potential for the exposure to blood borne pathogens has not present in the almost all workplaces. This danger occurs more than anything in health workers where they have a high risk of coming into contact with body fluids, including blood, of patients with pathology transmitted by this means that it is not valid to be in other types of work, since they would not be part of its risk matrix.

How are meiosis and mitosis similar?
O A. They happen at the same time.
B. They both produce new cells.
C. They both produce sex cells.
D. They both produce diploids.
Answer:
Both creates new cells
Explanation:
Meiosis and mitosis both results in the production of new cells. Therefore, the correct statement is option B.
What is meiosis?Mitosis and meiosis result in cell division and the production of new cells. In mitosis, two genetically identical daughter cells are formed by a parent cell and are responsible for the asexual reproduction of organisms.
In meiosis, four daughter cells are formed from a single parent cell which is genetically diverse, and each daughter cell receives half the number of chromosomes present in the parent cell. Meiosis is the process by which gametes (sex cells) are produced in organisms, and it is responsible for the sexual reproduction of the organisms.
Therefore, both mitosis and meiosis result in the production of new cells. However, mitosis results in the production of two identical daughter cells, whereas meiosis results in the production of four genetically diverse daughter cells.

PLS HELP!!! I WILL GIVE BRAINLY!!!!
Answer:
In many mammals, a developing embryo is nourished through the placenta. ____ is a connection with the mother. Later, a newborn takes in food produced by the blood artilleries of the mother. Unlike a young mammal, an insect or amphibian undergoes metamorphosis which is a series of dramatic changes in body shape and form.
In many mammals, the placenta, which connects the mother and the embryo, provides nutrition to the growing embryo. Oxygen and nutrients can be exchanged between the mother and foetus thanks to the placenta.
What is the mode of nourishment of an infant ?The infant then consumes nourishment made by the mother's milk. This milk, which the mother's mammary glands make, is nutrient- and antibody-rich and aids the infant's growth and development.
An insect or an amphibian goes through metamorphosis, which is a sequence of significant changes in body structure and form, unlike a newborn mammal. The insect or amphibian completely changes during metamorphosis from a larva or tadpole to an adult form the rearrangement of tissues and cells.

No decorrer das semanas, a lua apresenta diferentes aspectos. A causa para essas mudanças na aparência do satélite da terra é: A) a sombra da terra refletida sobre a lua. B) o movimento de rotação da lua em torno do seu próprio eixo. C) os raios solares que incidem na superfície da lua. D) a translação da lua ao redor da terra.
Answer:
C) the sun's rays that fall on the moon's surface.
Explanation:
The moon has different aspects and appearance because of the sun's rays that fall on the moon's surface. The shape of the Moon does not change itself, it occurs due to the sunlight. We only see that part of moon which is lit by the Sun. The phases of moon occur because the Sun lit different parts of the moon when the Moon revolves around the Earth so we can say that sun rays are responsible for the changing of shapes of the moon.

Explanation:
When plants with red flowers are crossed with plants with blue flowers, sometimes only red flowers are produced; other times either red or blue flowers are produced. Which gene is dominant?
Answer:
The colors you see in flowers come from the DNA of a plant. Genes in a plant's DNA direct cells to produce pigments of various colors. When a flower is red, for instance, it means that the cells in the petals have produced a pigment that absorbs all colors of light but red.
Explanation:
Dominant refers to the relationship between two versions of a gene. Individuals receive two versions of each gene, known as alleles, from each parent. If the alleles of a gene are different, one allele will be expressed; it is the dominant gene. The effect of the other allele, called recessive, is masked.
