Explain the difference between a humoral and a cell-mediated immune response.
Answer:
the main difference between the humoral immune response (HIR) and cell-mediated immune responses (CMIR) is : HIR provides immunity against antigens and pathogens in body fluids, while CMIR provides immunity against the body’s own cells that have either become cancerous or infected.

A company packages facial tissues into cube-shaped tissue boxes. Which units are most appropriate for measuring the side lengths of the boxes?.
The units that are most appropriate for measuring the side
of the boxes are meters.
The area of a cubeThe cube is made up of 6 square faces, 8 vertices and 12 edges. This means that to calculate the area of the cube, the area of a side is determined and then times by 6.
Area of a cube= (length×width) × 6
The length of an object and the distance between two objects are measured in meters and it is an internationally accepted method.
Therefore, the units that are most appropriate for measuring the side lengths of the boxes are meters.

Various species of the flowering plant of the genus Chrysanthemum have 18, 36, 54, 72, and 90 chromosomes. The variation is likely due to polyploidy.
What is polyploidy?Polyploidy can be defined as the number of complete sets of chromosomes in a given cell of an organism.
A diploid organism contains two complete sets of homo-logous chromosomes in its somatic cells.
Many organisms used polyploidy as an evolutionary strategy for adaptation to challenging environmental conditions.

Why is algal bloom around the edges of the Black Sea than spreading all over it?
Answer:
Algal bloom. Bright green blooms may also occur. These are a result of blue-green algae, which are bacteria (cyanobacteria). Some algal blooms are the result of an excess of nutrients (particularly phosphorus and nitrogen) into waters and higher concentrations of these nutrients in water cause increased growth of algae and green plants.
Explanation:
Assume that each finch comes from a large population of similar finches
in its particular environment. Imagine a drought in the environment of
Finch 1 makes the small seeds they normally feed off of scarce. Describe
how natural selection could cause the population of finches in the first
group to evolve over time to resemble the population of Finch 2.
Directional selection increased the frequency of individuals carrying the larger beaks and decreased the frequency of individuals carring small beaks.
What is directional selection?
Directional selection is a way in which natural selection acts by increasing the proportion of individuals with an extreme phenotypic trait.
This selection presents more frequently in those cases in which interactions between living organisms and the environment modify in the same direction.
How natural selection could cause the population of finches 1 to evolve over time to resemble the population of Finch 2?
In the exposed example, after the drought there were almost no seeds available for finch 1 to feed.
The introduction of a new allele to the population (by mutation or genetic flow) might have produced a few individuals with beaks similar to the one of Finch 2.
This beak was better for feeding. So individuals carrying this beak increased their fitness.
With time, the average size of the beaks was larger. The trait modification was related to the availability of only larger seeds with thick husks.
Eating large seeds with medium or small-sized beaks was impossible, so Finches needed to adapt, developing larger beaks to break bigger and harder seeds and eat the content.
Directional selection was responsible for the rapid change in the finches' beaks size after the drought.
The evolutive force modified the allelic frequencies, increasing the frequency of genetic variants that expressed the larger beak size and declining the frequency of the alleles that expressed smaller beak size.

Which are some characteristics of adaptive social behavior? Select three options. Occurs among members of the same species is not usually passed onto offspring is determined by natural selection increases an animal's likelihood of reproducing does not usually help an animal survive.
Adaptive social behaviours are animal behaviour they adapt in species community. It occurs among the same species, increases animals reproduction and is determined by natural selection.
What is adaptive social behaviour?The species of the organism exhibits a social adaptive behaviour among themselves to protect, reproduce, and survive. Aminals like insects, mammals and birds show adaptive social behaviours among their species.
This behaviour affects the reproduction of the species of the ecosystem and is subject to natural selection. An example of this behaviour is a group of ants together carrying food particles.
Therefore, option a. among species, c. determined by natural selection and d. increases reproductive chances are the characteristics of adaptive social behaviour.

I NEED HELP !!!!!!!
Answer:
Explanation:
To identify the different variables from this experiment, we must first understand what the different types of variables depict.
Independent variables are those variables that do not rely on the conditions of the experiment. They are what causes the experiment to proceed the way we want.
Dependent variables are the variables that rely on the effect of the independent variables. They are what we are actually testing for.
Controlled variables are the variables that are constant in an experiment and their outcomes are used to checkmate an experiment.
In the experiment by Justin:
Independent variable: water, coffee, milk
dependent variable: garden growth

What type of phase change does glacier caves have?
Answer:
Glacier caves form when ice at the bottom of a glacier comes into contact with volcanically heated rock below. The heat of the rock causes some of the ice to melt into liquid water and flow downhill, creating tunnels under the glacier. As the solid ice melts into liquid water, its molecules gain more freedom to move around. The molecules of liquid water become free to slide around each other.

photosynthesis equation with explanation
The photosynthesis equation is as follows:
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2
★ Carbon dioxide + water + energy from light produces glucose and oxygen
What is photosynthesis ?
Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism's activities.
More to know :-
There are two types of photosynthetic processes: oxygenic photosynthesis and anoxygenic photosynthesis. They both follow very similar principles, but oxygenic photosynthesis is the most common and is seen in plants, algae and cyanobacteria.
Explanation:
6CO2+ 6H2O sunlight and chlorophyll C6H12O6+ 6O2
it's a type of nutrition in which green plant manufacture their food using carbon dioxide and water in present of sunlight and chlorophyll
In a species of walruses, tusk size is controlled by a single gene that has only two alleles. The same species lives on two different sides of the Arctic Ocean. On one side, the amount of ice is much thicker and requires for walruses to have longer tusks to move out of the water. On the other side, the ice is not as thick and walruses have shorter tusks. Which of the following best describes the walruses in the two populations?
Adaptive alleles that are beneficial in one environment can be deleterious in another, due to selective pressures.
The species will eventually develop an intermediate tusk size in both populations.
The alleles of both populations will undergo directional selection to have the similar gene pools.
The species will risk decline if they continue to differ in allele frequencies and genetic diversity.

During photosynthesis, how is energy converted within the cell?.
Answer:
During the process of photosynthesis, light penetrates the cell and passes into the chloroplast. The light energy is intercepted by chlorophyll molecules on the granal stacks. Some of the light energy is converted to chemical energy. During this process, a phosphate is added to a molecule to cause the formation of ATP.
