Answer:
0.04 for 6 legs starfish and 0.96 for 5 legs starfish.
Explanation:
The allele frequency for the 6 legs starfish is 0.04 whereas, the allele frequency for the 5 legs starfish is 0.96 because there is only one 6 legs starfish in the given population as compared to 5 legs starfish. The low population of 6 legs starfish is due to the presence of recessive allele while on the other hand, higher population of 5 legs starfish is due to the presence of dominant allele. The allele frequencies for both population is done by dividing the allele of interest by total number of alleles present in the population.
Antihistamines make people drowsy because they A. block the effects of tuberomammillary hypothalamic neurons. B. inhibit the cholinergic nuclei in the brainstem. C. are selectively taken up by VLPO neurons. D. mimic noradrenaline and serotonin at several metabotropic receptors. E. excite several classes of neurons in the raphe.
Answer:
e.) block the effects of tuberomammillary hypothalamic neurons.
Explanation:
Antihistamines can be regarded as drugs that use in treating allergic rhinitis as well as other allergies. Antihistamines are been taken by people as inexpensive as well as generic, and over-the-counter drug which gives relief from nasal congestion, dust mites and also
sneezing and hives caused by pollen.
The first-generation antihistamine diphenhydramine which is a first generation is active ingredient found in Benadryl, which provide relieve against running nose and sneezing. It should be noted that Antihistamines make people drowsy because they block the effects of tuberomammillary hypothalamic neurons.
How does motion change
Answer:
The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion.
Explanation:
Answer:
The motion of an object is determined by the sum of the forces acting on it; if the total force on the object is not zero, its motion will change. The greater the mass of the object, the greater the force needed to achieve the same change in motion. For any given object, a larger force causes a larger change in motion.
A community ecologist would most likely study A. population growth of a single species. B. interactions among individuals of different species living in a small area. C. the cycling of matter through biotic and abiotic components of a geographical area. D. interactions among individuals of the same species living in a small area. E. energy flow through an ecosystem.
Answer:
The correct answer is B. interactions among individuals of different species living in a small area.
Explanation:
A community ecologist studies the set of populations of organisms of different species that inhabit and interact with each other in the same place for a period of time. The ecological community has to be studied as a unit or set and not independently each species of living beings that forms and interacts, that is, their distribution, organization, quantity, demography and reciprocity between the different populations that cohabit are included. Likewise, the main perspective of a community ecologist is found in the interrelationships between populations depending on the genotypic and phenotypic characteristics determined.

Cara is explaining to her sister how the solar system formed. Which description would she use to explain the solar nebula
A. a rotating cloud of dust and gas
B. a disk of material surrounding a young star
C. a small body from which planets form
D. a rocky core surrounded by a deep atmosphere of gas and ice
Answer:
The correct answer is A. a rotating cloud of dust and gas.
Explanation:
Nebulae are regions of the interstellar medium (clouds) made up of gases (mainly hydrogen and helium) and dust. In other words, nebulae are concentrations of gas in which we find hydrogen, helium and stardust in greater quantities. They are structures that are actually very important for the universe, this because inside it is the place where stars are born, which arise due to the condensation and aggregation of matter. The nebular theory states that the Solar System reached the form current from a solar nebula (a gas cloud), more than 4.5 billion years ago. The large cloud of molecular gas was affected by a certain phenomenon that would have taken place in the vicinity. Like the explosion of a supernova or the passage of a star that would produce a strong gravitational impact. The result of this event made the matter agglomerate in different places. The high concentration of matter caused the nebula to collapse. Becoming a protostar, (bodies whose characteristic is to be surrounded by clouds and contain preplanetary matter inside), that is, gaseous matter in the outermost part and solid inward. At the core of this structure, the temperature is so dominant that nuclear reactions take place to compensate for the gravitational force. This leads to a hydrostatic equilibrium and the formation of a fundamental star: the Sun. The rest of the mass flattened, forming a protoplanetary disk where the protoplanets were being formed, which would evolve to become the current planets, their satellites and the others bodies of the solar system.

what's the meaning of life if the end goal is death
Answer:
Some biology scientists believe life is all about sex and not dying, but it's not that simple.
Explanation:
Life is but a short period of time in this world, and the purpose of life is mainly to enjoy yourself while you live, live life to its fullest. But even better, to help shape a different world in which other people will benefit. You might only live for a few weeks, maybe 100 years, but you should do what you can in your life, help the community, and be proud of what you've accomplished within this world.

What factors caused the correlation between the reduction in skin pigmentation in humans and migration of human populations away from the equator?(1 point)
A) The exposure of human populations to predators only common to the polar regions caused them to adapt by camouflaging better with the environment.
B) The exposure of human populations to less UV light required a reduction in melanin to produce more vitamin D for healthier bones.
C) The exposure of human populations to new sources of food common to the polar regions caused changes in physiology that resulted in the production of less melanin.
D) The exposure of human populations to new diseases common to the polar regions interferred with melanin production causing lighter skin.
The exposure of human populations to new sources of food common to the polar regions caused changes in physiology that resulted in the production of less melanin.
What is relation of skin colur with geography?Skin color is lighter at high latitudes as compared to equator region beacuse of lower sunlight at higher altitudes and at polar regions. So due to less sunlight, less melanin is produced in our skin.
So we can conclude that option C is the right answer.
