Why do leaves appear green?
A. Green wavelengths are the highest energy.
B. Green wavelengths are the least used in photosynthesis.
C. Green wavelengths aren't used in photosynthesis.
D. Only green wavelengths are used in photosynthesis.
Answer:
The correct answer option is B. Green wavelengths are the least used in photosynthesis.
Explanation:
Plants have a pigment in them called as chlorophyll. This chlorophyll is able to absorb only certain wavelengths of the light within the light spectrum.
From that visible light spectrum, chlorophyll is only able to absorb light of red and blue wavelength. The green light is not absorbed by the by chlorophyll as it is reflected back.
Therefore, this reflection of green light makes the leaves to appear green.

Lucia is walking barefoot in her yard. She accidentally steps on a nail. How will her nervous system work to generate a reaction? Arrange the events chronologically.
Interneurons relay the impulse to motor neurons in the spinal cord.
She immediately moves her foot.
The sensory neuron generates an impulse.
Receptors in her toe receive stimuli.
Motor neurons signal the leg muscles.
Answer:
Correct order is
a) Receptors in her toe receive stimuli.
b) The sensory neuron generates an impulse.
c) Inter neurons relay the impulse to motor neurons in the spinal cord.
d) Motor neurons signal the leg muscles.
e) She immediately moves her foot.
Explanation:
Foot of Lucia contains stimuli receptors. As Lucia steps on the nail, the receptors in the toe receives the stimuli and hence her sensory neurons becomes active and they generate an impulse. These impulses are transmitted from sensory neurons via inter neurons to the brain. Brain processes the information and sends the message via inter neurons to the motor neurons. Motor neurons then signals the leg muscles and then she immediately removes her leg away from the pin.
Hence correct order is
a) Receptors in her toe receive stimuli.
b) The sensory neuron generates an impulse.
c) Inter neurons relay the impulse to motor neurons in the spinal cord.
d) Motor neurons signal the leg muscles.
e) She immediately moves her foot.
Final answer:
The events in the nervous system when Lucia steps on a nail form a reflex arc, starting with pain receptors and following through sensory neurons, interneurons in the spinal cord, motor neurons, and finally resulting in muscle contraction and movement.
Explanation:
The student's question pertains to the sequence of events that occur in the nervous system when Lucia steps on a nail. To answer this question, we will arrange the events in chronological order as they would happen within a reflex arc.
Receptors in her toe receive stimuli.
The sensory neuron generates an impulse.
Interneurons relay the impulse to motor neurons in the spinal cord.
Motor neurons signal the leg muscles.
She immediately moves her foot.
The sequence starts with the activation of pain receptors (nociceptors) when the nail is stepped on. This stimulus is then conveyed through sensory neurons to the spinal cord, where it is processed by interneurons.
The interneurons quickly transmit the impulse to motor neurons, which signal the leg muscles to contract, resulting in the immediate withdrawal of the foot. This entire process forms a reflex arc, allowing for a rapid response without the need for brain involvement.
Why does sexual reproduction result in more genetic variation in a species
than asexual reproduction?
O
A. In sexual reproduction, offspring have more chromosomes than
either parent
O
B. In sexual reproduction, offspring have fewer genes.
O
C. In sexual reproduction, offspring are not identical to either parent.
Answer: C. In sexual reproduction, offspring are not identical to either parent
Explanation:
Sexual reproduction results in more genetic variation because offsprings are not identical to either parent.
What is sexual reproduction?Sexual reproduction occurs when the sperm from the male parent fertilizes an egg from the female parent.Sexual reproduction involves the fusion of male and female gametes which leads to genetic variation.Crossing between male and female chromosomes takes place. Due to the crossing of chromosomes the child receives some features of the father and others of the mother.What is asexual reproduction?Asexual reproduction occurs when a single parent divides.It does not involve the fusion of gametes and the offspring will be identical to the parent.To learn more about Reproduction:

Answer:
It moves in an orbit around jupiter.
Final answer:
Ganymede is considered a moon instead of a planet due to its orbital relationship to Jupiter, despite its size compared to Mercury and Mars.
Explanation:
The reason why Ganymede is called a moon and not a planet despite its size compared to Mercury and Mars is that it moves in an orbit around Jupiter.
Moons are natural satellites that orbit planets, while planets orbit the Sun. Therefore, Ganymede's orbit around Jupiter classifies it as a moon, even though it is larger than Mercury and Mars.
Ganymede's classification as a moon is based on its relationship to Jupiter and its orbital behavior in the solar system.

Blank) reproduction allows for species to evolve or adapt to a greater range of conditions.
1. Asexual. 2. Sexual
Sexual reproduction allows for species to evolve or adapt to a greater range or conditions.
Sexual reproduction brings two sets of genes to the table to be passed to the offspring, since there are two parents. Asexual reproduction only has one parent so the offspring will only get one option of genes. This means that asexual reproduction does NOT allow adaptation.

C. In a heterozygote, both alleles combine to form an intermediate phenotype.
D. A heterozygote is considered a carrier for the recessive allele.
Answer:
In a heterozygote, both alleles are expressed. - is the best explanation of codominance.
Explanation:
Closely related to incomplete dominance is codominance, in which both alleles are simultaneously expressed in the heterozygote. Codominance is a relationship between two versions of a gene. Individuals receive one version of a gene, called an allele, from each parent. If the alleles are different, the dominant allele usually will be expressed, while the effect of the other allele, called recessive, is masked.
Option A. In a heterozygote, both alleles are expressed. - is the best explanation of codominance.

Briefly explain how nerve impulses travel in a body?
Answer:
When a nerve impulse reaches the end of an axon, the axon releases chemicals called neurotransmitters. Neurotransmitters travel across the synapse between the axon and the dendrite of the next neuron. Neurotransmitters bind to the membrane of the dendrite.
Nerve impulses travel through the body because of neurons.
In a neuron, stimuli always propagate in the same direction: they are received by the dendrites, go through the cell body, travel through the axon and, from the end of it, are passed to the next cell (dendrite - cell body - axon).
The nerve impulse that propagates through the neuron is of electrical origin and results from changes in the electrical charges on the outer and inner surfaces of the cell membrane.
The membrane of a resting neuron has a positive electrical charge on the outside (facing outside the cell) and a negative charge on the inside (in contact with the cell's cytoplasm). When that membrane is in such a situation, it is said to be polarized. This difference in electrical charges is maintained by the sodium and potassium pump. Thus separated, the electrical charges establish a potential electrical energy across the membrane: the membrane potential or resting potential (difference between the electrical charges across the membrane).
When a chemical, mechanical or electrical stimulus arrives at the neuron, there may be a change in the permeability of the membrane, allowing large sodium to enter the cell and small potassium to leave it. With this, there is an inversion of the charges around this membrane, which is depolarized generating an action potential. This depolarization spreads through the neuron, characterizing the nervous impulse.
Immediately after the impulse passes, the membrane undergoes repolarization, recovering its resting state, and the transmission of the impulse ceases.
The stimulus that generates the nervous impulse must be strong enough, above a certain critical value, which varies between different types of neurons, to induce depolarization that transforms the resting potential into an action potential. This is the threshold stimulus. Below this value, the stimulus only causes local changes in the membrane, which soon cease and do not trigger the nervous impulse.
Any stimulus above the threshold generates the same action potential that is transmitted along the neuron. Thus, there is no variation in the intensity of a nervous impulse due to the increase in the stimulus; the neuron obeys the "all or nothing" rule.
Thus, the intensity of the sensations will depend on the number of depolarized neurons and the frequency of impulses. Imagine a burn on your finger. The larger the burned area, the greater the pain, as more receptors will be stimulated and more neurons will be depolarized.
In a paragraph, explain what effect very large small pores and their diffusion rates would have on the workings and mechanisms of a cell
Answer:
Despite differences in structure and function, all living cells in multicellular organisms have a surrounding cell membrane. As the outer layer of your skin separates your body from its environment, the cell membrane (also known as the plasma membrane) separates the inner contents of a cell from its exterior environment. This cell membrane provides a protective barrier around the cell and regulates which materials can pass in or out.
Explanation:
MARK BRAIN LIST
Answer:
Small pores are effective in cellular transportation as compared to large pores.
Explanation:
If the pores of the cell membrane become large in size then the rate of diffusion into and out of the cell would be very fast. This is not a good situation as in an organism with uncontrolled/high rate of cellular transfers could lead to death of cells. Hence small pores are effective in maintaining the required permeability , material transfers across the membrane, turbidity and water pressure for osmosis.

Humans live most of their lives in the Troposphere, the lowest layer of the Earth's atmosphere. It contains the majority of Earth's weather patterns and breathable oxygen.
Explanation:Humans spend most of their lives in the atmosphere layer called the Troposphere. The Troposphere is the lowest layer of the Earth's atmosphere and is located directly above the surface of the Earth. This layer contains a majority of Earth's weather patterns and consists of most of the breathable oxygen that humans need for survival. The Troposphere's thickness varies from place to place, extending approximately 9 kilometers at the poles and up to 17 kilometers at the equator. Most commercial aircraft fly within this layer of the atmosphere due to its sufficient oxygen supply and steadier conditions.
