Which one of the following statements is true regarding voluntary and involuntary responses? A. Voluntary responses control the activity of glands. B. Voluntary responses originate in the sensory receptors. C. Involuntary responses are part of the autonomic system. D. Involuntary responses may include the spinal cord and not the brain.
Answers
Answer:
The correct answer would be C. Involuntary responses are part of the autonomic system.
The autonomic nervous system (ANS) is sub-division of the peripheral nervous system (PNS) mainly associated with involuntary responses.
It regulates the psychological actions such as heart rate, respiratory rates, digestion, urination, sexual arousal, pupillary responses, thermoregulation, fight and flight responses et cetera.

The roots of the aquatic plant hydrilla are poorly developed and lack xylem tissue. Which is an appropriate justification for this? 1.As hydrilla is aquatic in nature, the roots do not have to search for oxygen, and there is no need for xylem to absorb oxygen because the plant is surrounded by water that has dissolved oxygen in it. 2.As hydrilla is aquatic in nature, the roots do not have to search for minerals,and there is no need for xylem to absorb nutrients because the plant is surrounded by water that has dissolved nutrients in it 3.As hydrilla is aquatic in nature, the roots do not have to search for water, and there is no need for xylem to absorb water because the plant is surrounded by water.

b. they exhibit the same basic cell wall.
c. they perform the same mode of reproduction.
d. they have dna within their nucleus.
Answers
Answer;
D. they have DNA within their nucleus.
Explanation;
-According to evolutionary theory, diverse groups of animals evolve from one or a few common ancestors and the mechanism by which this evolution takes place is natural selection.
-Natural selection is the process by which traits that enhance survival and reproduction become more common in successive generations of a population.
-All forms of life are built of cells. A cell is the basic unit of the structure and function of living things. Living things may appear very different from one another on the outside, but their cells are very similar.

The release of stored energy from rocks that are deformed by stress is called elastic.
Elasticity is one of the properties of materials. Elastic materials deform when stress is applied. But when the stress is removed, they return to their original shape .

Final answer:
Introduction of snakes to a new habitat with varied rodent species will likely increase genetic variation in the snake population. The forces of natural selection, genetic drift, and possible mutation will drive this genetic diversity.
Explanation:
The introduction of the snake species to a new habitat with many types of rodents, which constitute their prey, will have an impact on the genetic variation of the snake population. This impact will largely be dictated by the forces of natural selection, genetic drift, and potentially mutation.
For instance, certain traits may favor the survival and reproduction of some snakes over others, depending on the exact nature of the predominant rodent species in the new habitat. This is known as directional selection. If the rodent types in the new environment favor the survival of snakes with certain traits, over time, these traits will become more common among the snake population.
Additionally, genetic drift, which refers to random fluctuations in allele frequencies, may also come into play, especially if the initial snake population in this new environment was relatively small. Over time, these factors, along with potential mutations, can contribute to increased genetic variation within the snake population.

Answers
Answer:
The correct answer is option A,
Explanation:
The Population density of any species in an ecosystem is equal to the number of that species living in one unit of area.
Thus , population density can be represented as
Substituting the given values in above equation, we get -
A population density is the number of animals per 1 m2.
So, this problem can be solved by using a proportion:
If 60 raccoons live in 10 m2, how many raccons will live in the 1 m2.
60 raccoons : 10 m2 = x raccoons : 1 m2
60 raccoons : 10 = x raccoons
x raccoons = 6 raccoons
Thus, the population density is 6 raccoons per m2.
