Within a population, the different colors and patterns of eyes are _____. A. the results of chance mutations B. reflections of the colors in the environment C. produced in anticipation of environmental forces D. created by the environmental effects on the phenotype
Answer: the correct option is B.
reflections of the colors in the environment
Explanation:
This is because the environment causes different reflections of color. Fir example white light reflect colors, it will absorb all other colors except with.
The environment serves a a medium for color reflection and this has lead to different color and patterns in population. People have eye pattern and color base on their surrondings, what the surronding is made off influence the color and patterns.

Little brown bats are a species of bat in the genus Myotis. Little brown bats are extremely common in North America, where they roost in houses, buildings, or trees. In the winter, the bats hibernate in caves, unused mines, or other similar locations. Unfortunately, little brown bats are threatened due to white-nose syndrome. Given these terms related to bats, match the term to the level of biological organization.all little brown bats
Answer: population: The bat species of North America
community : a little brown bat
organism: bat
Explanation:
Here, the population of the bat resides in the North America in the houses, trees and buildings they hide in the caves in winters for hibernation. Inside the cave they form a bat community here the organism is bat. These bats are threatened in numbers due to white nose syndrome. The white nose syndrome is the fungal growth on the wings and muzzles of the bats. The fungus affects the bats during hibernation, when the bats trying to save their energy by reducing their metabolic rate. It is transferrable from one bat to another thus can infect the entire population of bat. It is a dangerous disease.
How is the carbon cycle related to sedimentary rocks?
Answer: Heat and pressure compress the mud and carbon over millions of years, forming sedimentary rock such as shale. ... The heated rock recombines into silicate minerals, releasing carbon dioxide. When volcanoes erupt, they vent the gas to the atmosphere and cover the land with fresh silicate rock to begin the cycle again.

Scientists were investigating a pond of water found deep in a South American cave along the Yucatan Penisula. They obtained many samples which they took back to their lab. After much testing, they found that the water has an acidic pH of 3. Another much more surprising discovery was that a new species of a unicellular organism was present in the samples. The organism was observed with a microscope and found to not have a bound nucleus or organelles. To which Domain would this organism be classified?

What is Bacteria?Eukarya is not the correct answer because they have organelles and a nucleus. Archaea is not the correct answer because they have organelles and a nucleus.
Microbes known as bacteria have simpler cell structures than many other types of creatures. One DNA loop serves as their command center and houses all of their genetic data. Instead of a nucleus, some bacteria have an additional ring of genetic material called a plasmid.
Genes that offer the bacterium a competitive edge over other bacteria are frequently found in the plasmid. For instance, it might have a gene making the bacterium immune to a specific antibiotic.
Therefore, Bacteria is the correct answer because it lacks organelles or a nucleus. Protista is not the correct answer because they have organelles and a nucleus.

o It has no Rh antigen on its red blood cells that can be attacked by the antibodies in the other blood types.
O It has no A and B antigens on its red blood cells that can be attacked by the antibodies in the other blood types.
Answer:
the first one: It has no antibodies that can attack the antigens on the red blood cells of the other blood types.
Explanation:
edge 2021
AB positive and O negative are considered as universal blood types. AB+ has no antibodies that can attack the antigens on the red blood cells of the other blood types. The correct option is A.
What is universal receiver?The people with AB+ blood group are called as the universal receivers. They can safely receive a blood transfusion using any other blood type. Having a universal blood type can save a life of yours or someone else in an emergency.
If you have an AB+ blood type, you have both A and B antigens. Since a person has all of the antigens that are possible, this blood type is the rarest. The AB+ blood type has a positive Rh factor, the recipient will not reject the blood. So it can get any type of blood.
AB type blood has no antibodies against type A or type B blood. So a person with AB blood can receive any type of blood.
Thus the correct option is A.

Bruce Wallace (1963) established a laboratory population in which the recessive allele lt was at a frequency of 0.5. He propagated the population for 10 generations, and determined the frequency of lt each generation.
a. True
b. False
Answer:
a. True
Explanation:
Bruce Wallace was a professor emeritus of genetics who performed many population studies. He worked in 1958 at the University of Cornell as a professor of genetics. In 1963, he performed a population study wherein the recessive allele It was at a frequency of 0.5. The population was propagated for 10 generations and the frequency of It for each generation was determined.
The result of this study showed that lt/lt died without reproducing, whereas, individuals with genotype +/+ were normal.
When farmers clear a forest and plant crops, how will the biodiversity of the land be affected?
The biodiversity will decrease with higher populations of fewer species,
The biodiversity will increase with lower populations of more species.
The biodiversity will decrease with lower populations of more species.
The biodiversity will increase with higher populations of fewer species.
Answer:
The biodiversity will decrease with lower populations of more species.
Explanation:
This is because clearing a forest destroys habitats and therefore kills animals as they have no shelter, no food source and no water source.

D. anaerobic, heterotrophic bacteria
The theory of primitive life on Earth is fascinating, there are countless scientists who try to explain how life began on Earth, but to be able to answer how the first living beings were we need to know that.....
Oparin and Haldane hypothesis
The most widely accepted hypothesis about the origin of life today is the Oparin and Haldane hypothesis. According to this idea, the primitive Earth would be constituted by
AmmoniaHydrogenMethane and Water vapor,which are constantly expelled by volcanic activities. The condensation of this water vapor gave rise to a cycle of rains, as these, upon reaching the still hot surface of the Earth, evaporate again, thus initiating a new cycle.
Through the action of the sun's ultraviolet radiation and constant electrical discharges, the elements present in the atmosphere began to react, giving rise to the first organic compounds, called amino acids. The rains carried these compounds to the primitive oceans, which formed when the Earth's surface cooled, allowing water to accumulate on the surface.
In primitive oceans, these amino acids joined together, forming protein-like compounds (proteinoids), and then, after further reactions, these gave rise to coacervates. These became more stable and complex, controlling their own chemical reactions and being able to self-duplicate, thus giving rise to the first living beings.
Heterotrophic and autotrophic hypotheses
Some authors believe that the first organisms would be heterotrophs. This was due to the fact that the first organisms were simple, lacking the structure to carry out a more complex biochemical process to obtain food, for example, photosynthesis. Thus, these organisms fed on simple organic matter, presenting as the end product of this process carbon dioxide (CO2) and alcohol (C2H5OH), that is, the first living organisms would be fermentors.
With this information, we can say that the first living being on the planet was anaerobic, heterotrophic bacteria.
D. anaerobic, heterotrophic bacteria
There have always been many theories about the origin of life on the planet, but this is the most acceptable among scientists, but it is necessary to know that they are not yet fully proven, so they continue as a theory.
