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.

Which of the following best explains what will happen if the blood gets too cold? A) It will have a high viscosity and increased resistance. B) It will have a low viscosity and increased resistance. C) It will cause low blood pH and decrease resistance. D) It will change the shape of blood cells and decrease resistance.
It will have a high viscosity and increased resistance.
Effect of temperature on bloodLow temperatures cause narrowing of blood vessels and arteries which leads to restricting blood flow and reducing oxygen to the heart.
Our heart must pump harder to circulate blood through the blood vessels which results in increasing of our blood pressure and heart rate.

You are infected with a pathogen; it is your first exposure to this pathogen. The first antibody types that will eventually appear in your blood to help fight this infection will be:
If it is the first time that this pathogen comes into contact with the immune system, IgM antibodies are produced, which are the first type of antibodies produced against a certain microorganism.
Immunoglobulins are molecules that intervene in defense processes against microorganisms and infections.
Each type of immunoglobulin is specific against a certain antigen, this is what allows an immunological memory to exist, which is obtained when coming into contact for the first time with a certain microorganism.IgM is the first immunoglobulin synthesized by the neonate by itself, and it is also the first to appear during the primary response, which lasts an average of three weeks and then disappears.In general, the production of IgM antibodies precedes that of IgG, the concentration of antibodies can be high, plateau for a few days and then decrease rapidly.Therefore, we can conclude that when the immune system first comes into contact with an antigen, a primary response occurs; mediated by IgM antibodies.

Which of the following is NOT part of the non-specific immune response?
A. Inflammation
B. Phagocytosis
C. Antibodies
D. Interferons
D. Interferons are not a part of the non-specific immune response.
What is the function of interferons?Interferons were first described as an antiviral thing that interferes with viral replication in mammalian cells (10). they're secreted from inflamed cells and spark off an innate immune reaction that promotes now not best cytokine production but additionally herbal killer mobile features and antigen presentation.
Interferons (IFNs) — the body's first line of antiviral defense — are cytokines that are secreted by host cells in reaction to virus infection. by using inducing the expression of hundreds of IFN-inspired genes, numerous of that have antiviral capabilities, IFNs block virus replication at many ranges.
Interferons are a circle of relatives of clearly-happening proteins which are made and secreted with the aid of cells of the immune gadget (an example, white blood cells, natural killer cells, fibroblasts, and epithelial cells).

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.
