There is a complex just beneath the brain that functions as a neurohemal organ. The epithelial cells found in this complex may be secretory as well, but this has not been proved. Neurohormones are released from the infracerebral complex into the coelomic fluid through which they travel to their targets.
it it is located at the base of the brain near the pituitary gland it's very small the hypothalamus plays a crucial role in many important functions include releasing hormones regulating body temperature.

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.

Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d). A pigment-eyed, dimple-chinned man marries a blue-eyed woman without a dimpled chin. Their firstborn child is blue-eyed and has a dimpled chin. What are the possible genotypes of the father
Answer:
PpDD and PpDd
Explanation:
Pigmented eyes (P) are dominant to non-pigmented (p), and dimpled chins (D) are dominant to Non-dimpled chins (d).
The possible genotypes of a pigment-eyed, dimple-chinned person would be PPDD, PpDd, PPDd, PpDD while a blue-eyed person without a dimpled chin would have the genotype ppdd.
The genotype of a blue-eyed, dimpled chin child would be either of ppDd or ppDD, but in this case, the mother is ppdd and as such, the child cannot have two copies of D allele. Hence, the genotype of the child can only be ppDd.
In order for the child to have blue eyes (pp), it means that the father has to have the non-pigmented allele (p). This also means that the father is heterozygous for eye pigmentation (Pp).
Hence, the genotype of the father is now limited to PpDD and PpDd.

Mendel used more than 28,000 pea plants in his experiments. How did such a large sample size improve the reliability of his results?
A. Using many plants ensured that both males and females were available.
B. Using more plants made the experiments much faster.
C. Using more plants was necessary because some were unable to reproduce.
D. Using many plants gave results that supported his prediction of ratios.
Answer:
D. Using many plants gave results that supported his prediction of ratios.
Explanation:
Using more plants in any experiment, such as this one, will make the results more accurate.
By using more pea plants, Mendel's prediction was more supported by the results. A larger sample size will allow the ratios to be more reliable compared to a smaller sample size.

A.littering
B.CFCs
C. oil spill
D.runoff
Quick this is a timed exam
Answer:
B) CFCs
Explanation:
chlorine in the CFC is very harmful to the ozone layer
Air pollution is the contamination of the air and its surroundings due to air pollutants. Chlorofluorocarbons (CFCs) are most likely a source of air pollution. Thus, option B is correct.
What are Chlorofluorocarbons?Chlorofluorocarbons (CFCs) are nontoxic chemicals that contain chlorine, fluorine, and carbon. They are largely used in the manufacturing of refrigerants, foams, sprays, etc.
Chlorofluorocarbons destroy the protective ozone layer of the earth and affect its ability to shield the harmful UV rays from the sun. Due to their dangerous effect on the ozone, they are banned.
They are emitted and get deposited in the earth's atmosphere causing the greenhouse effect that causes the melting of the ice and increases in the sea level to rise in temperature.
Therefore, chlorofluorocarbons are the source of air pollution.

A HOX gene called Pax6 is required for developing light sensing eyes (or eye-like structures) in a range of taxa including Cnidaria, Mollusca, Arthropoda, and Chordata. Humans (Chordata) and squid (Mollusca) have complex eyes with many shared features, like a lens, that are NOT found in other taxa that have eyes or eye-like structures. Which of the following statements is TRUE?A. If human eyes and squid eyes are analogous, then the Pax6 gene in humans and squid will be nearly identical.B. If human eyes and squid eyes are analogous, then their shared common ancestor would also have complex eyes.C. If human eyes and squid eyes are homologous, then the Pax6 gene in humans and squid will be nearly identical.D. If human eyes and squid eyes are homologous, then they have independent evolutionary origins.

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.

Match the characteristics below to either seedless or seed plants.
________vascular plants only

________reproduce by spores
________ gymnosperms and angiosperms
________ vascular or nonvascular plants
________ monocots and dicots
Answer:
Seed
Seedless

Seedless
Seed
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.

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.

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.
