Vaccines are given to provide protection against pathogen causing infections. Which of
the following statements best describes how vaccines work?
Group of answer choices
A. Antibodies in the vaccine provide the body with nonspecific immunity to an antigen.
B. Fever and swelling develop which is the first response in killing a pathogen.
C. An inactivated or killed virus stimulates the body to develop specific immunity to that type of virus.
D. Heathy bacteria causes the body to release toxins which will protect the body if later exposed to different type of bacteria.
Answer: Vaccines contain weakened or inactive parts of a particular organism (antigen) that triggers an immune response within the body. Newer vaccines contain the blueprint for producing antigens rather than the antigen itself. Regardless of whether the vaccine is made up of the antigen itself or the blueprint so that the body will produce the antigen, this weakened version will not cause the disease in the person receiving the vaccine, but it will prompt their immune system to respond much as it would have on its first reaction to the actual pathogen.

What are three advantages to sexual reproduction?
restricts chromosomal combinations
produces resistance to unfavorable conditions
Produces disease-free seed plants
produces more uniform individual organisms
produces genetic variations
Answer:
1. produces genetic variations.
2. produces resistance to unfavorable conditions.
3. produces disease-free seed plants.
Explanation:
Sexual reproduction causes more genetic variation. More genetic variation results in diverse immune systems and traits that are advantageous to survival. Variation is good because it allows a species to adapt to new environments.
The advantages of sexual reproduction is produces resistance to unfavorable conditions, produces genetic variations and produces disease-free seed plants.
What do you mean by sexual reproduction?Sexual reproduction is a type of reproduction that involves a complex life cycle in which a gamete with a single set of chromosomes combines with another gamete to produce a zygote that develops into an organism composed of cells with two sets of chromosomes.
A disadvantage is that sexual reproduction takes longer than asexual reproduction. A mate must be found, the egg must be fertilised by sperm, and then the offspring develop.
Three mechanisms contribute to genetic variation arising from sexual reproduction: independent assortment of chromosomes, crossing over, and random fertilization.

Ciliated ependymal cells: A) help form the blood-brain barrier. B) circulate cerebrospinal fluid. C) form myelin in the brain and spinal cord. D) serve as wandering phagocytes during brain injury.
Ciliated ependymal cells: circulate cerebrospinal fluid.
Ependymal cells are a type of epithelial cell that is associated with the cavities of the body through which the cerebrospinal fluid circulates.
They are part of glial cells, which share space with neurons in the nervous system.They create the membranes that keep cerebrospinal fluid circulating through the ependymal canal of the spinal cord and the cerebral ventricles.For this, the ciliated structure that these cells present is essential for a correct movement of the cerebrospinal fluid, preventing it from spilling through other tissues and passing to areas of the body where it should not be.The cilia move rhythmically creating tiny currents for fluid to flow through the central nervous system.A small fraction of highly specialized and modified ependymal cells, called choroidal cells, are responsible for generating this essential fluid.Therefore, we can conclude that ciliated ependymal cells circulate cerebrospinal fluid.

Explain how the rate of cooling magma affects the size of
the crystal that form.
Answer: When magma cools, crystals form because the solution is super-saturated with respect to some minerals. If the magma cools quickly, the crystals do not have much time to form, so they are very small. If the magma cools slowly, then the crystals have enough time to grow and become large.

Does “survival of the fittest apply to domesticated animals? Why or why not? *
Answer:
Yes.
Explanation:
This survival of the fittest is instinct helps domestic animals live. Just because an animal is domesticated, does not mean that instincts go away. Those instincts like hunting may get suppressed, but not taking away.
Answer:
Survival of the fittest does not apply to domesticated animals. This is because these animals don't live in the wild so they don't have to run after things and kill them. Their food comes out of a tin and is provided by human beings. They don't have any predators so their lives are seldom at risk. Thus, they don't need to be fitter or more powerful than other animals in any way.
Lets take the example of pet dogs. We keep them for our support or simply because we enjoy their company. We provide them with food, shelter etc. and protect them. Since, we basically do everything for them; they need not evolve into a stronger, more powerful species.
However, in the case of stray dogs, they have to fight for their survival. They have to fight with other dogs for food and shelter. Hence, survival of the fittest will apply here as the strongest dog gets to eat.

How many carbon atoms does glucose have
Answer:
six carbon atoms
Explanation:
Glucose has an aldehyde group (-CHO) on carbon atom number one and is therefore called an “aldose,” also it has six carbon atoms (a hexose) so it can be called an “aldohexose.” The reactive group on fructose, however, is a ketone group (-C=0) on carbon number two.

What are two types of evidence that support the hypothesis that earth and the rest of the solar system was formed by a condensing nebula
Comets, Asteroids and metoeorites support the hypothesis that earth and the rest of the solar system was formed by a condensing nebula.
What are the functions of asteroids?An asteroid is a minor planet of the inner Solar System. Sizes and shapes of asteroids vary significantly, ranging from 1-meter rocks to a dwarf planet almost 1000 km in diameter; they are rocky, metallic or icy bodies with no atmosphere.
They probably consist of clay and silicate rocks, and are dark in appearance. They are among the most ancient objects in the solar system. The S-types ("stony") are made up of silicate materials and nickel-iron. The M-types are metallic (nickel-iron).
Almost all of the asteroids in our solar system are orbiting in a broad band 19,400,000 miles wide between Jupiter and Mars. The asteroids are orbiting the Sun, each one traveling around the Sun fast enough for the orbits not to degrade.

If the environment gets cold, humans will often respond involuntarily by shivering in order to:
a. keep body temperature the same as the external temperature
b. increase body temperature
C. decrease body temperature
d. regulate blood pressure
Answer:
increases body temperature
Explanation:
this is because when you shiver your blood vessels contract which then increases your body temperature
If the environment gets cold, humans will often respond involuntarily by shivering in order to increase body temperature. So, the correct option is B.
What do you mean by Environment?An environment may be defined as anything that is present in the surroundings of living entities that is either biotic or abiotic.
The process of shivering causes the blood vessels to contract and relax at a rapid rate to maintain homeostasis. The signals of rapid contractions are sent by the hypothalamus through nerve impulses.
Therefore, the correct option for this question is B.

For which one of the following functions is parenchyma tissue particularly suited?
A. Reinforcement and support C. Elasticity
B. Exchange of gases D. Formation or root hairs
Reinforcement and support
parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion, food storage, and other activities of plant life. Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls).

Chlorophyll appears green because it…?
Answer:
Chlorophyll gives plants their green color because it does not absorb the green wavelengths of white light. That particular light wavelength is reflected from the plant, so it appears green. Plants that use photosynthesis to make their own food are called autotrophs.
Answer:
A. absorbs green light
B. reflects green light
C. emits green light
ANSWER: B. reflects green light
Explanation:
our eyes can only see what objects reflect, so if it's appearing green then obviously it's reflecting the green light.
