Answer: Involuntary.
The Autonomic nervous system is a subdivision of the Peripheral nervous system and it is in charge of the involuntary processes in the body such as blood pressure, respiration and the heart rate. As such, its effectors are under involuntary control.
The Autonomic nervous system controls the smooth and cardiac muscles in the body as well as the glands. This is where it earns its other name, the Visceral nervous system.
Explanation:
Which of the atomic models represents the most reactive element?
A. Argon, because it has three energy levels with eight electrons in the third level.
B. Lithium, because it has two energy levels with one electron in the second level.
C. Aluminum, because it has five energy levels with two electrons in the third level.
D. Carbon, because it has two energy levels with four electrons in the second level.
The most reactive element is represented by the atomic model for lithium, which consists of two energy levels with an electron in the second level. So, the correct option is B.
What is Reactive element?A reactive element is one that forms chemical bonds with other elements to obtain a stable electron configuration. Reactive elements are chemically unstable. The amount of valence electrons in an element's highest energy level determines how reactive it is.
The element with the fewest number of energy levels and most reactive valence electrons in the above example is lithium, which has only two energy levels and one electron in the second level. Lithium in this state has one valence electron, which makes it very reactive and predisposed to form bonds with other elements filling its outermost shell.
Therefore, the correct option is B.

What does biodiversity mean ?
Answer:
biodiversity mean Biodiversity, also called biological diversity, the variety of life found in a place on Earth or, often, the total variety of life on Earth.
Explanation:
Answer: Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.
Explanation: Usually three levels of biodiversity are discussed—genetic, species, and ecosystem diversity.
Genetic diversity is all the different genes contained in all individualplants, animals, fungi, and microorganisms. It occurs within a species as
well as between species.
Species diversity is all the differences within and between populationsof species, as well as between different species.
Ecosystem diversity is all the different habitats, biological communities,and ecological processes, as well as variation within individual ecosystems.

What is the phenotypic ratio of the F2 generation?
Answer:
9:7
Explanation:
We get the dominant phenotype in plants that have at least one dominant allele of EACH of the two genes; otherwise we get the recessive phenotype. So, the observed ratio in the F2 generation is 9:7.

Sand for beaches comes from rocks in the area that are weathered down, and
their sediment is deposited in the area beaches. The beaches are then eroded,
and the sediment is moved away from the beaches. If rocks stopped weathering,
how would the beach change?
Answer:
Beaches would shrink until they were no longer there because the sediment is pulled away from the shores by the tide and there would be no new rock sediment to replace the old rock sediment.
An example of an involuntary movement would be -
A dancing
B swing a club
C heartbeat
D walking
Answer:
C. heartbeat

Answer:
Option C
Explanation:
Because the rhythm is not something that we do voluntarily. We're not able to control the movements of our heart and therefore Heartbeat is an example of involuntary movement.

A freckled man marries a woman without freckles. They have four children, two with freckles, and two without freckles. What are the genotypes of all these people?
Answer:
The genotype of the father: Ff
The genotype of the mother: ff
The genotype of the two children without freckles: ff
The genotype of the two children with freckles: Ff
Explanation:
Freckles (F) are is dominant trait, so one dominant allele in the genotype of an individual will cause he/she to have freckles. Since the father has freckles, but only two of his children has freckles; that means that he has a heterozygous genotype. In the Punnett Square, the offsprings' genotypes are shown, as well as the parents'.
A freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.
What is the significance of the freckle trait?There are both dominant and recessive traits that determine the person's quality, such as freckles, which are dominant over being freckleless. When the parents with freckles cross with the parents without freckles, they will produce half the freckles and half the freckleless. The parent with a freckle is heterozygous (Ff), so two types of gametes will be produced, such as F and f, and will form Ff and ff offspring when crossed with the freckleless parent (ff).
Hence, a freckled man marries a woman without freckles, and they have four children, two with freckles and two without, so the genotype of the parents are Ff, ff and the children with freckles are Ff, while the freckleless are ff types.

An area surrounded by tall mountains contains a very large, isolated population of green and white peacocks. During the mating season, the male peacocks demonstrate flashy feather displays to attract females, who usually choose green peacocks over white ones. A biology student tabulates the following information.
Genotype
Plumage Color % of Population Allele Controlled Phenotype
FF or Ff
Dark green
84%
F (dominant)
Dark green plumage
ff
White
16%
f (recessive)
White plumage
Using this information, the student plans to use the Hardy-Weinberg equation to predict the allele frequencies in future peacock generations. Why would her research advisor have a problem with this? (2 points)
Group of answer choices
The student needs the percent of the population with the Ff genotype in order to find the F frequency.
Her research advisor would first want her to find the males' mating success rate for the calculations.
The peacocks are sexually selective when choosing mates, so future allele frequencies may drift.
Since the peacock population is isolated, its alleles would shift away from Hardy-Weinberg equilibrium.
Answer:
The peacocks are sexually selective when choosing mates, so future allele frequencies may drift.

distinguish between absorption and reabsorption in the mammalian body
Answer:
Tubular reabsorption is the process that moves solutes and water out of the filtrate and back into your bloodstream. This process is known as reabsorption, because this is the second time they have been absorbed; the first time being when they were absorbed into the bloodstream from the digestive tract after a meal.

Vascular resistance is due to friction between blood and the walls of the blood vessel. Which of the following causes low vascular resistance?
obesity
dehydration
high blood pressure
cholesterol levels within normal range
Answer:
Cholesterol levels within normal range
Explanation:
Vascular resistance is due to friction between the blood and the walls of the blood vessel, and cholesterol levels within the normal range can cause low vascular resistance, which is the last option.
What is vascular resistance?Vascular resistance is the resistance to blood flow in the blood vessels, which is determined by the diameter of the blood vessels, blood viscosity, and the length of the blood vessels, so when blood flows through the blood vessels, it experiences frictional forces due to the interaction between the blood and the walls of the blood vessels, obesity, dehydration, and high blood pressure can all contribute to increased vascular resistance.
Hence, the correct answer is that cholesterol levels within the normal range can cause low vascular resistance, which is the last option.
