Answer:
a. Make antibodies
Explanation:
B-cells is one of the two types of lymphocytes or white blood cells produced in the marrow of the bone (the other being T-cells). B-cells are a part of adaptive or acquired immunity in our body i.e. a learned defense after a pathogen might have penetrated.
B-cells help combat foreign Invaders that make way into the body by producing ANTIBODIES, which are specific to a particular pathogen. Note that, the B-cells learnt to combat based on a previous infection of such pathogen. In response to an antigen, the B-cells produce the plasma cells, which in turn produce the antibodies.

In our neighborhoods we have garbage people that come around and
collect garbage and waste at you home. What does that inside of the cell.
Answer:
The answer is lysosomes
Explanation:
Lysosomes are membrane bound organelles that contain degradative/digestive enzymes which are used to digest/degrade/break down unwanted or worn out cellular organelles through a process known as autophagy.
The reason the answer is lysosomes is because the waste (unwanted or worn out organelles) use to be a useful part of the home (cell), however, there is another organelle responsible for absorbing and neutralizing toxins in the cell; it's called peroxisomes

what keeps earth from flying outward into space from its present position
Answer:
Gravitational pull and the earth on its axis
Explanation:
Hope this helps
Gravitational pull and the earth on its axis keeps earth from flying outward into space from its present position.
what is Gravitational force ?A gravitational force is defined as an attractive force which is exerted by a massive body on the massive body. So our body always tries to pull other body towards itself due to this gravitational force.
gravitational force is a force exerted by earth on other objects and can be represented as F=mg
F is the force of gravity, G is the gravitational constant of the universe and it is always the same number, M is the mass of one object, m is the mass of the other object (measured in kilograms, kg), r can be the distance those objects are apart (measured in meters, m)
This force can also be called as Newton's Universal Law of Gravitation And the object that are really far apart from each other don't pull on each other noticeably either.

If you have a 20% sugar solution and a 45% sugar solution how does the 20%
solution compare to the 45% solution?
Answer:
It is 25% less
Explanation:
That is all i can say
A close comparison of the 20% solution to the 45% solution shows that the 20% solution is actually less than 50% of the 45% solution.
Arithmetically, you discover that the 20% solution is 25% or 0.25 (45% - 20%) less than the 45% solution.Comparatively, you can compute that the 20% solution actually represents 44.4% or 0.444 of the 45% solution (20% x 45%). The same result can be obtained by first dividing 20% by 45% and then multiplying the resulting dividend by 100.Thus, the result of the comparison shows that there is more sugar in the 45% solution than there is in the 20% sugar solution.

2. How does the development of a nervous system and sense organs relate to increasing complexity of multicellular animals?
The development of nervous system and sense organs in multicellular organisms has led to evolution of species in a more complex manner.
Complexity of multicellular organisms• The development of nervous system and sense organs has permitted for a greater level of perception and better equipped organisms.
• It has permitted the organisms to collect resources, react to their surroundings, and take advantage of their surroundings.
• This has resulted in the organisms to survive longer and accommodate into bigger types of body.
• Such amendments has thus permitted organisms to become more complex and move up the food chain.
Thus, the development of nervous system and sense organs is associated with increasing complexity of multicellular animals.

would that change what we see?
The visible light spectrum. Redshift and blueshift describe how light shifts toward shorter or longer wavelengths as objects in space (such as stars or galaxies) move closer or farther away from us. ... When an object moves away from us, the light is shifted to the red end of the spectrum, as its wavelengths get longer.
The "calico" pattern of coat coloration in female cats is a result of:__________
a. fragile X syndrome
b. x chromosome inactivation
c. unequal crossing over
d. endoreduplication
e. Turner syndrome
Answer:
b. x chromosome inactivation
Explanation:
As you know, female cats have an x chromosome inherited from their mother and an x chromosome inherited from their father. After these two chromosomes are inherited and determine the sex of the cat, one of them will be disabled at some point in fetal development. Inside the X chromosome is the gene that determines the coat color of cats, when one of the two x chromosomes is deactivated, the other x chromosome will have all of its cells activated. In this case, if the activated chromosome is the one that has genes for the "cheetah" pattern of the coat color, all the descendants of this female cat also have the same coat.

The person above is right
Punnett squares are used to predict all possible allele combination of a genetic combination. Therefore, option (B) is correct.
What is a punnett square?The Punnett square is a diagram in the form of a square that is utilized for the purpose of predicting the genotypes that will result from a specific cross or breeding experiment. Reginald C. Punnett, who came up with the method in 1905, is honored with the naming of this technique. The diagram is utilized by biologists so that they can calculate the likelihood of a future generation inheriting a particular genotype.
A Punnett Square is a useful tool that helps to predict the variations and probabilities that can result from cross breeding. This can be done by comparing the offspring of two different species. This includes the estimation of the likelihood of sexually reproducing humans, animals, and plants.
