Sierra is asked to demonstrate how carbon travels from the atmosphere to living organisms, then back to the atmosphere. She draws a diagram showing carbon dioxide from the atmosphere being taken in by a plant. An animal then consumes the carbon dioxide in the plant, uses it as a source of energy, then exhales, returning the carbon dioxide to the atmosphere. Which of the following statements indicates a correction that needs to be made on Sierra's diagram?
Answer: An animal then consumes the carbon dioxide in the plant, uses it as a source of energy, then exhales, returning the carbon dioxide to the atmosphere.
Explanation: This is incorrect, because animals consume oxygen released by plants, then exhale the carbon dioxide into the atmosphere.
Answer:
B
Explanation:
Animals do not use carbon dioxide as an energy source; they use sugars or starches.

What change is most likely
responsible for the trout decline? *
Answer:
Rise in temperature.
Explanation:
Increase in temperature is responsible for the decline in the population of trout because trout needs low temperature for better growth and survival. Due to more consumption of fossil fuels in vehicles and industries, more carbondioxide gas is released which causes air pollution. This air pollution increases the temperature of the earth surface known as global warming due to which the cold areas become warm and as a result the trout population decreases.
Road construction has isolated a small population of a beetle population from the main population. This newly isolated population has very different allele frequencies than the main population, most probably because
Answer:
genetic drift
Explanation:
The newly isolated population of beetle would have very different allele frequencies than the main population because of genetic drift.
Genetic drift refers to a change in the frequencies of alleles in a population over generations brought about by pure chance. Genetic drift can cause a bottleneck or founder effect. A bottleneck effect is a temporary decrease in the genetic diversity of a population while the founder effect refers to a decrease in the genetic variability of a new population formed from a small number of individuals that get separated from a larger population.
Hence, the newly formed population of beetles would have lower allele frequencies than the main population due to the founder effect brought about by genetic drift.

How do the colors of light affect photosynthesis? Which color was most efficient, medium and least?
Answer:
blue is the most efficient while green is the least efficient
Explanation:
It is well known that different photosynthetic pigments can absorb light at different wavelengths. Thus, the amount of light absorbed during photosynthesis depends on the color of the source light. The leaves have green color because chlorophyll is a photosynthetic pigment that absorbs light at all wavelengths and reflects green light. The best wavelengths are those at 430–450 nm (blue range) and 600–700 nm (red range), thereby photosynthesis is most efficient when plants are illuminated by light sources that emit blue and red lights. Moreover, sources that emit light at the green wavelength are least efficient for photosynthesis.

Which statement best describes how some trees respond to decreasing
temperatures and shorter days in the fall?
Answer: they drop their leaves and go into dormancy
Explanation:
Answer:
they drop their leaves and go into dormancy[
Explanation:
With a light-sensitive chemical, plants can sense the differences in day length. For example, in the fall, when the days start to get shorter, the trees sense that there is less sunlight. The plant is stimulated, and it sends messages telling the leaves to change colors and fall.

The map of a walking trail is drawn on a coordinate grid with three points of interest. The trail starts at R(−2, 4) and goes to S(3, 4) and continues to T(3, −1). The total length of the walking trail is ___
Answer:
The total length will be "10 units". A further explanation is given below.
Explanation:
The given points are:
R(−2, 4)
S(3, 4)
T(3, −1)
On applying the distance formula,
⇒ [tex]RS=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
⇒ [tex]=\sqrt{(3-(-2))^2+(4-4)^2}[/tex]
⇒ [tex]=\sqrt{(3+2)^2+(0)^2}[/tex]
⇒ [tex]=\sqrt{25}[/tex]
⇒ [tex]=5 \ units[/tex]
and,
⇒ [tex]ST=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]
⇒ [tex]=\sqrt{(3-3)^2+(-1-4)^2}[/tex]
⇒ [tex]=\sqrt{0+(-5)^2}[/tex]
⇒ [tex]=5 \ units[/tex]
Now,
The total trail length will be:
= [tex]RS+ST[/tex]
= [tex]5+5[/tex]
= [tex]10 \ units[/tex]

Explanation:
The matching of characteristics with respect to either seedless or seed plants are as follows:
Seed plants: Vascular plants only.Seedless plants: bryophytes and pteridophytes.Seedless plants: reproduce by spores.Seed plants: gymnosperms and angiosperms.Seedless plants: vascular or nonvascular plants.Seed plants: monocots and dicots. What are Seedless plants?Seedless plants may be defined as those plants that do not hold seeds for propagation. They are completely devoid of seeds.
Seedless vascular plants are those plants that possess vascular tissue but do not construct flowers or seeds. Such types of plants generally reproduce by the utilization of haploid and unicellular spores instead of seeds.
The example of such types of plants commonly include ferns, mosses, liverworts, etc. They included the categories of plants like bryophytes and pteridophytes.
Seed plants generally contain well-defined seeds and the process of reproduction generally occurs with the help of seeds instead of spores. They generally included plant categories like gymnosperms and angiosperms.
Therefore, the matching of characteristics with respect to either seedless or seed plants is described above appropriately.

What might be the evolutionary significance of the switch from asexual to sexual reproduction that occurs in some species when the environment becomes unfavorable
Explanation:
The evolutionary significance of the switch from asexual to sexual mode of reproduction in some species under unfavorable environmental conditions is because of the need of More mutations and variations can be made in the species. The asexual mode causes the making the same copy so when there needs to be change.
In this lab, we discussed several explanations for the evolution of bipedalism. Each hypothesis has its drawbacks and has been criticized. It’s your turn to hypothesize why our lineage evolved bipedalism. Describe some of the advantages of bipedalism (be sure to think about what life would have been like for our ancestors millions of years ago when bipedalism evolved, including their risk of predation, food availability, environment, etc.). Are there any disadvantages to bipedalism? If so, what are they? Taking into account these possible advantages and disadvantages, why do you think bipedalism might have evolved?
Answer and Explanation:
One of the main disadvantages of bipedalism is that it makes it impossible for mothers to carry their young efficiently. This is because bipedalism stimulates the spine's reaction, which may cause the puppies to slip and stay behind, or to be caught by predators. Thus, bipedalism impairs the maintenance of the species, as it leaves the puppies vulnerable.
Bipedalism also causes a decrease in the speed of the body that must be fighting gravity at all times. This can hinder the hunting and flight of predators, which, again, impairs the survival of the species.

In two to three sentences, describe why Prunnett squats do not accurately demonstrate how asexual reproduction passes on traits.
Answer:
Punnett Squares are unable to predict the offspring of an asexual organism because there is only one parent from which the offspring can receive genes from. The whole point of a Punnett Square is the fact that it covers all possible offspring outcomes besides mutations from the usual two parents.

Neurotransmitters are defined by four essential characteristics. These are: Neurotransmitters are synthesized within presynaptic neurons. Depolarization of a neuron results in the release of a neurotransmitter, which exerts a multitude of actions on the postsynaptic neuron. Their action on postsynaptic neurons can be replicated by administering a drug that mimics the activity of the endogenous neurotransmitter. Their action in the synaptic cleft is terminated by a specific action. A, C, and D only
Answer:
The correct answer is A, C, and D only.
Explanation:
A neurotransmitter is a biomolecule, generally synthesized by neurons, which is poured from vesicles in the presynaptic neuron into the synaptic gap and produces a change in the action potential of the postsynaptic neuron. Depending on the nature of the neurotransmitter, this can be synthesized in the neuronal soma or in the nerve endings. Some neurotransmitters are synthesized directly in nerve endings thanks to enzymes that have been synthesized in the soma and transported to these endings. Through the interior of the axon flows a current of substances free or enclosed in vesicles, which can be precursors of both neurotransmitters or their enzymes, called axonal flow.Another characteristic of the transmitter function in each of the substances commonly accepted as neurotransmitters is that when administered exogenously as a drug that in reasonable concentrations perfectly mimics the effects of the endogenously released transmitter.
Neurotransmitters should be defined by four essential characteristics. It involved the A, C, and D only.
What are Neurotransmitters?Neurotransmitters refer to the chemical messengers in the body that should transform the message from the nerve cell. Also, it should be synthesized in neurons and stored in the presynaptic terminal. It should be the vital attribute at the time when the chemical should mimic the activity of endogenous due to which it gets a similar response. Also it eliminates the activation site.
