Why do you think type 2 diabetes occurs so much more often than other inheritable diseases? Propose a hypothesis for why this allele has not been eliminated by natural selection.
Which type of species best describes a mouse: opportunistic or equilibrium? Explain why a mouse or rat population would continuously grow while other mammals (cheetahs) are nearly extinct.
Answer:
This allele has not been eliminated by natural selection because it may confer an adaptive advantage for particular environmental conditions
Mice and rats are opportunistic species. These species can rapidly adapt to different environmental conditions, while cheetahs are unable to adapt to changing environments.
Explanation:
An allele is a gene variant that may be beneficial, neutral, or deleterious for a particular environment. Different alleles are not eliminated by natural selection against other alleles (even when a priori seem to be deleterious) because they confer a selective advantage in a given environment. For example, the allele for sickle cell anemia is caused by a point mutation which is lethal in homo-zygous individuals, but heterozygous individuals are less likely to die of malaria, thereby this allele has been positively selected in geographic areas where malaria is an endemic disease. Moreover, mice and rats are opportunistic species, i.e., they are species that rapidly adapt to varied living conditions. These species are characterized to have high growth rates and produce many offspring. On the other hand, the cheetah is a highly specialized species that is unable to adapt to changing environments. In consequence, cheetah populations are more prone to become extinct than rat and mice populations.
Which of these organelles prepares proteins to be fully functional?
A. Rough endoplasmic reticulum
B. Large vacuoles
C. Smooth endoplasmic reticulum
D. Chloroplasts
Rough endoplasmic reticulum
Answer:
Rough endoplasmic reticulum is among the organelles that are found in eukaryotic cells. The reason as to why it is called rough is because it has ribosomes attached to its surface. Its main function is to produce proteins.
Explanation:
When you pushed the diaphragm up what change occurred in chest cavity pressure? Explain how this change in chest cavity pressure affected the lungs.
Answer:
positive pressure
Explanation:
Exhalation is a passive process during which the intercostal muscles and the diaphragm relax. The ribs move downward and inward, while the diaphragm rises. This movement causes the chest to decrease in size and positive pressure to build inside the chest cavity. The positive pressure pushes air out of the lungs.

You have a microorganism you know is both fastidious and which normally lives in human lungs. Which medium might this organism have the highest probability of growing on and why
Answer:
It is likely that this microorganism grows in enriched culture media.
Explanation:
As shown in the question above, the microorganism that lives in the lungs is extremely demanding. This means that this microorganism is very difficult to be cultivated in a culture medium, as it requires specific nutrients and in specific amounts to be able to develop. These microorganisms are called fastidious microorganisms and need an enriched culture medium to develop.
Enriched culture media are those that have a high range of nutrients in their composition. These culture media are highly nutritious and for this reason, they are the ideal environment for demanding microorganisms, as it can efficiently meet the needs of this organism.

Explain the role of cellular respiration in a cell.
Answer:
Every cell performs a type of cellular respiration as it is required to produce energy. The point of cellular respiration is to turn high-energy molecules, know as glucose, into ATP, a form of usable energy. There are two types of respiration, aerobic and anaerobic. Aerobic goes through 3 stages and produces the most ATP by using oxygen and releasing carbon dioxide. Anaerobic does the same job but only uses one stage and produces much less ATP. This process gives the cell energy and continues the carbon cycle.
Tell me how bacteria make their energy and other chemical products.

hi,I was feeling so bored so I give this question What is climate change and what r the causes of climate change?
Answer:
Climate change is the global phenomenon of climate transformation characterized by the changes in the usual climate of the planet (regarding temperature, precipitation, and wind) that are especially caused by human activities
Humans are increasingly influencing the climate and the earth's temperature by burning fossil fuels, cutting down forests and farming livestock. This adds enormous amounts of greenhouse gases to those naturally occurring in the atmosphere, increasing the greenhouse effect and global warming. Humanity’s increased use of fossil fuels – such as coal, oil and gas to generate electricity, run cars and other forms of transport, and power manufacturing and industry
Deforestation – because living trees absorb and store carbon dioxide
Increasingly intensive agriculture – which emits greenhouse gases like methane and nitrous oxide
What is a controlled variable?
Answer: A controlled variable or constant variable is a variable that does not change during an experiment.
Explanation:
A controlled variable or constant variable is one which the researcher holds constant (controls) during an experiment. It is also known as a constant variable or simply as a control.The control variable is not part of an experiment itself it is neither the independent nor dependent variable but it is important because it can have an effect on the results gotten.
example of a controlled variable is temperature.
Which critter trait is affected by an environmental factor, such as light, temperature, or
diet? Explain.
Answer:
Tallness.
Explanation:
Tallness is the critter trait that is affected by an environmental factor, such as light, temperature, or diet because the organism remains short if they are not getting food properly as well as temperature. Food provides essential nutrients that contribute in the growth of organism. Suitable temperature of the body allows the different functions in the body to be done which directly affects the growth of the body and the organism becomes taller.

What is the probability that a hybrid individual with the genotype AabbCcddEeFf will produce a gamete that has the genotype abCdeF
Answer:
6.25%
Explanation:
Find the number of different gametes that can be produced
number of gametes produced = 2^n
n is the number of allele pairs that are heterozygous
there are 4 heterozygous allele pairs, these are: Aa, Cc, Ee and Ff
2^4 = 16
abCdeF is one of the 16 genotypes that could be produced
to find the percentage, divide 1 and 16 and multiply by 100
1 ÷ 16 = 0.0625
0.0625 × 100 = 6.25

A microbiologist is conducting a research project on chemolithoautotrophs. This means that the investigator is examining certain aspects of a bacterium that is a purple nonsulfur bacteria which depends on light. uses light as its energy source and carbon for organic compounds. can oxidize inorganic molecules such as ammonia and sulfur for energy. can use the energy from sunlight to build organic molecules from carbon dioxide. obtains carbon from organic molecules.
Answer:
uses light as its energy source and carbon for organic compounds.
Explanation:
The purple non-sulfur bacteria which depends on light produces organic food just like plants through the process of photosynthesis. The purple non-sulfur bacteria uses carbondioxide and water with sunlight produces oxygen and glucose which is an organic compound. So that's why purple non-sulfur bacteria is also known as phototrophic means organism that produces their own food through photosynthesis.
The most direct method by which an ion or molecule can move across a cell membrane is by ____________.A. using an integral protein.B. a sodium-potassium pump.C. simple diffusion. D. active transport.E. osmosis.
Answer:
C. Simple diffusion
Explanation:
Simple diffusion from a high to low concentration is the most direct method that ions or molecules can move across a cell membrane.
Through this method, no proteins are required for transport, and no energy is used.
The ion or molecule being transported directly moves across the cell membrane, without any other factors involved.
So, the correct answer is C. Simple diffusion

Mode of action of aldehydes and Quaternary ammonium compounds is
Answer:
Aldehydes have antibacterial, antifungal, antiviral and sporicidal activity. These are helpful to destroy the spores of Bacillus subtilis and Clostridium sporogenes. Glutaraldehyde and formaldehyde are commonly used aldehydes in disinfectants.
Quaternary ammonium compounds work by denaturing the proteins of the bacterial or fungal cell, affecting the metabolic reactions of the cell and causing vital substances to leak out of the cell, causing death.
ason Kimble's study of the Archaea in Snowy River in Fort Stanton Cave showed that Archaea play an important role in __________.
Answer:
Ecosystem.
Explanation:
Archaea play an important role in ecosystems with organisms that derive or produce energy from oxidation of methane. Many of Archaea are bacteria which are often a major source of methane in such environments and they can play a role as primary producers. Archaea is important for scientists because it has unique ecological roles and can also generate energy differently i.e. responsible for producing biological methane which no eukaryotes or bacteria can do that.

What is the answer with explaining
Answer:
EeWw
Explanation:
The allele for the earlobe is depicted as e while that of the hairline is w.
A parent that is homzygous recessive for earlobes (ee) and homzygous dominant for hairline (WW) would have the genotype eeWW.
The other parent that is homzygous dominant for unattached earlobes and homzygous recessive for hairline would have the genotype EEww
eeWW x EEww
During meiosis, each genotype will form gametes.
eeWW: eW, eW, eW, eW
EEww: Ew, Ew, Ew, Ew
These gametes will randomly unite during fertilization to produce offspring. Since the same gametes are formed by each parent:
eW x Ew
offspring
100% EeWw (see the attached image for the Punnet's square)
The genotype of all the children would be EeWw and would phenotypically be with unattached earlobes and dominant hairline.
