Compare and contrast innate immunity and adaptive immunity.
Answer: the difference between innate and adaptive immunity is that innate immunity is a fast immune response that provides the first line of immunological defense against infections while adaptive immunity is a slow immune response mediated by the T and B lymphocytes.
Explanation:
In pea plants, tall (T) is dominant to short (t). A plant with genotype Tt is crossed with a plant with type tt. What percentage of their offspring will be tall?
Answer:
50%
Explanation:
Draw a Punnet square to determine the percentage of offspring that are tall.
The green and blue highlighted columns and rows represents the genotype of the parents. To fill in the genotype of the offspring, write down the letter (T/t) of the parent allele from that row and column the offspring belongs to. By convention, the T is written before t. (The genotype of a tall offspring is written as Tt not tT)
Since the T allele is dominant, as long as the offspring has one T, the offspring is tall. The t allele is recessive, thus two ts (tt) is needed for the short trait to be expressed.
From the Punnet square, the result is 2 offsprings that are tall and 2 offsprings that are short.
Required percentage
[tex] = \frac{2}{4} \times 100\% \\ = \frac{1}{2} \times 100\% \\ = 50\%[/tex]
Suppose the light converged before reaching the back of the eye.
What lenses would be in the person's glasses to help them see? Explain
your choice.
Answer:
z
Explanation:
If the light converges before reaching the back of the eye, this means that the person is nearsighted and has trouble seeing objects that are far away. To correct nearsightedness, the lenses in the person's glasses would need to divert the light before it entered the eye. Therefore, the glasses would have concave lenses.
what are lenses?If the light converges before reaching the back of the eye, it means that the person is suffering from a refractive error known as myopia, or nearsightedness. To correct myopia, the lenses in the person's glasses should be concave, which means they are thicker at the edges and thinner in the center. Concave lenses are designed to diverge light rays, which helps shift the focal point of light farther back so that it falls directly on the retina. By doing so, the glasses help the eyes see distant objects more clearly.
Hence, if the light converges before reaching the back of the eye, this means that the person is nearsighted and has trouble seeing objects that are far away. To correct nearsightedness, the lenses in the person's glasses would need to divert the light before it entered the eye. Therefore, the glasses would have concave lenses.

How does the body protect itself from the majority of pathogens it encounters?
Answer:
In general, your body fights disease by keeping things out of your body that are foreign. Your primary defense against pathogenic germs are physical barriers like your skin. You also produce pathogen-destroying chemicals, like lysozyme, found on parts of your body without skin, including your tears and mucus membranes. In response to infection, your immune system springs into action. White blood cells, antibodies, and other mechanisms go to work to rid your body of the foreign invader. The immune system has a vital role: It protects your body from harmful substances, germs and cell changes that could make you ill. It is made up of various organs, cells and proteins.
Once infected cells have sensed an invading pathogen, they secrete molecules called cytokines and chemokines. These cells are then primed to resist an infection with the invading virus. Cytokines such as interferons activate anti-viral genes in the infected and neighbouring cells.
Microorganisms capable of causing disease—or pathogens—usually enter our bodies through the eyes, mouth, nose, or urogenital openings, or through wounds or bites that breach the skin barrier. Organisms can spread, or be transmitted, by several routes.
The second line of defense is nonspecific resistance that destroys invaders in a generalized way without targeting specific individuals: Phagocytic cells ingest and destroy all microbes that pass into body tissues. For example macrophages are cells derived from monocytes (a type of white blood cell).
If pathogens do manage to enter the body, the body's second line of defense attacks them. The second line of defense includes inflammation, phagocytosis, and fever.
Answer:
your skin protects itself because of all the oils on your glands .. but when you get a cut the while blood cells trap and eat them

45. If we put ANY type of cell in pure water: a) is pure water considered hypotonic, hypertonic or isotonic? b) would the cell shrivel or swell? c) what would happen to its turgor pressure (water pressure inside cell): increase or decrease?
Answer:
Explanation:
Pure water is an hypotonic solution that allows for diffusion of water into the cell and the cell will begin to swell.
The movement of water into the cell will make the cell swell but if water is moving outside the cell will collapse and shrink.
The turgor pressure is usually found withing the cell it ensures the movement of solutes when water is taken into the cell, the turgor pressure will increase. When water is taken out of the cell, the pressure will reduce.

Adhesion: the attraction force between different types of molecules.
define cyclosis and plasmolysis
Answer:
Cyclosis- streaming of cytoplasm within a living cell without deformation of the external cell membrane. In some plant cells there is a rapid rotatory cytoplasmic movement, which is limited to the peripheral parts of the cell next to the cell wall; chloroplasts and granules move in this stream.
Plasmolysis is the process of shrinkage or contraction of the protoplasm of a plant cell as a result of loss of water from the cell. Plasmolysis is one of the results of osmosis and occurs very rarely in nature, but it happens in some extreme conditions.

What happens when sugar solution is filtered
Answer:
The water passes through the filter paper.
Explanation:
Since sugar is able to dissolve completely in water, sugar solution is a homogenous mixture and thus its composition is uniform throughout and is able to be filtered out without separating its components.

Answer:
The correct answer is - in the sickle-cell hemoglobin is the replacement of glutamic acid with valine in the β-globin amino acid chain.
Explanation:
Sickle cell anemia has a mutant gene in which that produces has valine amino acid instead of glutamate in the hemoglobin protein. In the given question the structure of the protein has only one difference that is the replacement of the glutamic acid in normal hemoglobin to valine in the β-globin amino acid chain in the mutant protein.
Valine 6 (beta chain) binds to a different hydrophobic patch (on the alpha chain and causes the disease in sickle cell anemia cases.
