In contrast to the previous mouse example: A heterozygote carrying a dominant allele is selected for differently. For example, if in a heterozygote of A1A2 the A2 allele providing a camouflage advantage was dominant, then how does that affect selection?
A heterozygote carrying a dominant allele is selected differently. If in a heterozygote of A₁A₂ the A₂ allele providing a camouflage advantage was dominant, then the individual would have a higher chance of survival and reproduction.
This is because the dominant allele A2 would be expressed and provide the individual with the camouflage advantage, even though they also carry the A1 allele. As a result, the A2 allele would be more likely to be passed on to future generations and increase in frequency in the population. This is an example of positive selection, where the dominant allele conferring an advantage is favored by natural selection.

_________ _____________ gas moves into the stomata because it is a __________ of photosynthesis. ____________ gas movee out of the stomata because it is a _____________ of photosynthesis.
Why might a cactus have fewer stomata than a plant found in a tropical region?
If you were looking at leaves of an aquatic plant, where would most of the stomata be on the leaves (top or bottom)? ________ Why?
Carbon dioxide gas moves into the stomata because it is a reactant of photosynthesis. Oxygen gas moves out of the stomata because it is a product of photosynthesis.
Cacti often have fewer stomata than plants found in tropical regions because they live in arid environments and are adapted to reduce water loss
Most of the stomata on the leaves of an aquatic plant would be found on the top of the leaves.
Photosynthesis is a process by which plants, algae, and some bacteria convert light energy into chemical energy in the form of organic compounds such as glucose. This process requires carbon dioxide (CO₂) as a reactant and produces oxygen (O₂) as a by-product.
Stomata are tiny pores on the surface of leaves that allow for gas exchange between the plant and the environment. They are surrounded by specialized cells called guard cells, which can open and close the stomata depending on the plant's needs.
Cacti often have fewer stomata than plants found in tropical regions because they live in arid environments and are adapted to reduce water loss. Since stomata are the primary means by which plants lose water, cacti and other desert plants typically have fewer of them.
Most of the stomata on the leaves of an aquatic plant would be found on the top of the leaves. This is because aquatic plants have adapted to living in water, which provides them with ample access to carbon dioxide. Because they don't need to lose water to acquire carbon dioxide, aquatic plants have evolved to reduce their stomata, which helps to prevent water loss. Additionally, since sunlight can penetrate through water, photosynthesis can still occur on the top surface of the leaves, where the stomata are located.

(0.5) Diluting bacteria to count colonies on plates:
A. A bacterial sample has a concentration of 2 x106 CFU/mL. You make 1 mL serial dilutions of 10-1, 10-2, 10-3, 10-4. You finally plate 0.1 mL of the 10-3 dilution on an agar plate and incubate it at 370C. How many colonies do you expect to see on the plate?
B. You see 10-fold more colonies than you had expected to see when you plated 0.1 mL of the 10-3 dilution in A. What could have gone wrong? How will you fix this problem?
A. To calculate the number of colonies you expect to see on the plate, you need to multiply the original concentration of the bacterial sample by the dilution factor and the volume plated:
Original concentration = 2 x 10⁶ CFU/mL
Dilution factor = 10⁻³
Volume plated = 0.1 mL
Expected number of colonies = Original concentration x Dilution factor x Volume plated
= (2 x 10⁶ CFU/mL) x (10⁻³) x (0.1 mL)
= 200 CFU
Therefore, you expect to see 200 colonies on the plate.
B. If you see 10-fold more colonies than you had expected to see when you plated 0.1 mL of the 10⁻³ dilution, it could mean that there was an error in the dilution process. Perhaps you accidentally used a higher concentration of the bacterial sample, or you didn't mix the dilutions properly. To fix this problem, you should repeat the dilution process carefully, making sure to use the correct concentrations and to mix the dilutions thoroughly. You may also want to check your calculations to make sure you didn't make any mistakes in calculating the expected number of colonies.

One of the controversial discussions in the medical community today is whether or not there is any infection control danger from wearing scrubs in public. There are two main arguments regarding this issue. One side argues that there is no evidence to support the idea that wearing scrubs in public poses a danger, while the other side argues that there is evidence to support this idea.
The first argument, that there is no evidence to support the idea that wearing scrubs in public poses a danger, is based on the fact that there have been no studies conducted to prove that there is a link between wearing scrubs in public and the spread of infection. This argument is supported by the fact that many healthcare professionals wear scrubs in public without any negative consequences.
The second argument, that there is evidence to support the idea that wearing scrubs in public poses a danger, is based on the fact that there have been numerous studies conducted that have shown that scrubs can harbor dangerous bacteria and viruses. This argument is supported by the fact that there have been numerous outbreaks of infection in hospitals that have been linked to contaminated scrubs.
Overall, there are pros and cons to wearing scrubs in public. The pros include the fact that scrubs are comfortable and easy to wear, and that they are a symbol of the healthcare profession. The cons include the fact that scrubs can harbor dangerous bacteria and viruses, and that they can contribute to the spread of infection.

Why do you sometimes get 36 ATP and sometimes get 38 ATP from cellular respiration?
The reason why we sometimes get 36 ATP and sometimes get 38 ATP from cellular respiration is due to the efficiency of the electron transport chain.
During cellular respiration, glucose is broken down into two pyruvate molecules, which then go through the Krebs cycle to produce ATP, NADH, and [tex]FADH_{2}[/tex]. These molecules are then used in the electron transport chain to produce ATP.
The efficiency of the electron transport chain can vary, which can result in the production of either 36 or 38 ATP molecules. If the electron transport chain is less efficient, it will produce 36 ATP molecules, and if it is more efficient, it will produce 38 ATP molecules.

What is the requirement of asexual reproduction ?Asexual reproduction does not require the formation of gametes or fertilization, it can occur quickly and efficiently, allowing organisms to reproduce without the need to find a mate or expend energy on producing and caring for offspring.
This can be particularly advantageous in environments where conditions are stable and resources are abundant, as asexual reproduction allows populations to rapidly increase in size and take advantage of available resources.
Another advantage of asexual reproduction is that it allows for the efficient transmission of advantageous traits from parent to offspring. Because asexual reproduction results in offspring that are genetically identical to the parent, any advantageous mutations or adaptations that the parent possesses will be passed on to its offspring.
Therefore, This can allow populations to quickly adapt to changing environmental conditions or to take advantage of new resources without having to wait for the slow process of natural selection to act on new mutations.
