a fossil that is older than 200 million years old can be found on land due to plate tectonics
A fossil that is older than 200 million years old can be found on land due to plate tectonics.
Plate tectonics is the movement and interaction of large sections of the Earth's lithosphere (outermost layer of the Earth) over the asthenosphere (part of the Earth's mantle). This movement can cause the formation of mountains, oceans, and the breakup of continents over millions of years. The movement of plates can also result in the uplift and exposure of rock layers that were previously buried deep beneath the surface, including those containing fossils that are millions of years old.
Therefore, it is possible to find fossils that are more than 200 million years old on land due to plate tectonics, but the process of uplift and exposure of such rocks may take millions of years and require various geological processes.

Explain why the phenotypes associated with the human FXN gene can be studied in a mouse cell. Unlike skeletal muscle cells, heart muscle cells cannot rely on fermentation for long. Explain the inability of heart muscle cells to function using only fermentation for metabolism. ATP acts as a negative feedback regulator of phosphofructokinase, one of the enzymes in glycolysis. Predict the eventual effect of ATP on pyruvate production in heart cells that express excess amounts of the normal frataxin.
Answer:
Heart muscles have long refractory period.
Explanation:
Heart muscle cells cannot rely on fermentation for long period of time because heart muscles have long refractory period which does not allow it to use the fermentation process. They have rich blood supply and have capillary density 4 times more than normal skeletal muscles. The anaerobic capacity is limited in the heart which does not allow the heart muscle cells to use fermentation process for metabolism. Our heart requires oxygen in large amount and very quickly for ATP production.

A non hemophiliac father and a hemophiliac mother have a son what is the percentage chance that the son will be hemophiliac?
Answer:
50%
Explanation:
He will have hemophilia if he inherits his mother's X chromosome with the hemophilia gene. He will have normal blood coagulation if he receives his mother's other X chromosome. So a carrier's son has a 50% risk of inheriting hemophilia. Each son has a 50% risk of having hemophilia. Each daughter has a 50% chance of inheriting the hemophilia gene. Each daughter has a 50% risk of having hemophilia.

The process of restoration when the mining activities stop in a particular area depends on how much affected the area is. Before the exploitation of the soil, there are nutrients that species like microorganisms, as bacteria, use to carry on their metabolic functions. As a result of these processes, there is a particular disponibility of other resources plants take through their roots to also develop their own biological functions.
Having this clear, the removal of these particular nutrients, that goes away with the extracted minerals, causes several impacts too difficult for restoration processes to reverse. This is why, almost in terms of a human lifetime, the recovery of the original conditions of that particular area wouldn't have been reached. Only with the pass of hundred or thousands of years, and with the action of microorganisms and intensively ecologic work, that area would be recovered.

7. Suppose you were culturing a population of bacteria at 15 degrees Celsius and then raised the temperature of the culture to 37 degrees Celsius. What effect do you think this might have on the fatty acid composition of the membrane? On the transition temperature of the lipid bilayer? On the activity of membrane desaturases?
Answer:
See below
Explanation:
An increase in the temperature will result in greater fluidity of the lipid bilayer membrane, since the unsaturated fatty acids are increased. The membrane tends to be stiff at lower/colder temperatures.The transition temperature refers to the temperature at which the membrane goes from solid to liquid state, which will be raised in this case. This is due to the increase in saturation of fatty acids.The activity of the enzymes membrane desaturases will decrease under these conditions.Why would low genetic variability within a species pose a danger to the population?
A population cannot evolve in response to changing environmental variables .
What is Population ?
Population refers to the total number of individuals of a particular species or group that live in a defined geographical area or region. In demography, population is often studied as a demographic variable, with data being collected and analyzed to understand patterns of growth, aging, migration, and other factors that influence the size and composition of a population. The study of population is important because it helps us to understand the impacts of various social, economic, and environmental factors on human well-being and sustainable development. In addition to providing valuable information on current and future population trends, the study of population can also help us to understand the interplay between population and other factors, such as economic growth, health, and the environment.

Explanation:
A 50 mL sample of soup was found to be contaminated with E. coli. A dilution of the soup was prepared by adding 14 mL of the soup to 20 mL of water. This was then diluted 1/60, and finally 10-3. Then .25 was added in to 2 plates. The first plate had a colony count of 72 and second had 65.
To do the dilution series does the 50 need to be added?
Answer:
The answer is "\(\bold{4.0 \times 10^7 \ \frac{CFU}{mL}}\)"
Explanation:
The very first thing we must do is figure out where the plate was really a countable sheet. By default, at least 30 and 300 colonists must have been on a computable plate. It is deemed incorrect beyond and below this range. We also will pick the studded 0.25 size, leading towards 72 and 65 colonies. Now calculate the double average.
\(\to 72+ \frac{65}{2} = 68.5\)
We need to calculate its dilution factor for both the second item. Increase for all of this
All of the dilutions you also made:
\(\to \frac{7}{17} \times \frac{1}{60} \times \frac{1}{1000} \\\\= \frac{7}{1020000}\\\\= 6.8 \times 10^{-6}\)
\(\to \frac{14 \ ml \ soup}{14 \ ml} + 20\ mL\\\\\)
\(\to \frac{CFU}{mL} = \frac{Colonial \ number}{Dilution \ Factor \times Volume \ plated}\\\\\)
\(= \frac{68.5}{6.8 \times 10^{-6} \times 0.25 \ mL} \\\\ = 4.0 \times 10^7\)
Why do light-fur mice survive LESS often on dark rocks, compared to dark-fur mice?
Answer:
for a creature with a lighter fur color it is next to impossible to blend into darker colored environments compared to darker fur colored creatures
The light fur mice survive less on the dark rocks compared to the dark fur mice. The reason is the light fur mice can be easily visible by the Predator and eaten by them.
What is adaptation?An adaptation is a process in which an organism tries to adapt with the environment in order to protect itself from the predator. There are different types of adaptation seen in the animal kingdom, such as mimicry.
An example is mice fur coloration on the dark rocks. Dark rocks have dark coloration. When dark-furred mice live on this type of rock, their colour will mix with the dark colour of the rock. As a result, they can't be clearly visible to the predator's eye. Predators that are present at a distance, such as birds can't distinguish between the rock and the dark mouse's fur. This increases their chance of survival. When a light fur-colored mouse lives on the dark Rock, it can easily be differentiated by the Predator and eaten by them.
Hence, light colour fur mice survives less than the dark fur mice on the dark Rock as they can easily be seen by predators.

(c) Predict the growth rate pattern of the E. coli-M bacteria when they are initially added to the growth medium if the mutation does not interfere with glucose utilization.
(d) Provide reasoning to justify your prediction.
The question is incomplete. The complete question is :
Glucose is the preferred carbon source for Escherichia coli bacteria. Researchers isolated E. coli-M, a strain of E. coli with a single mutation that inactivates a key enzyme in one of the three glycolytic pathways E. coli bacteria use to break down glucose. In an initial experiment to study the effect of the mutation on glucose utilization and ATP production by the bacteria, the researchers add 2×104 E. coli-M bacteria to 400 mL of a growth medium that contains glucose. To measure the rate of bacterial growth, they monitor the optical density of the culture as a measure of bacterial concentration over time.
(c) Predict the growth rate pattern of the E. coli-M bacteria when they are initially added to the growth medium if the mutation does not interfere with glucose utilization.
(d) Provide reasoning to justify your prediction.
Solution :
c). It is given that Glucose is preferred as the carbon source for the Escherichia coli bacteria or the E. coli-M bacteria. If the growth medium of the E. coli-M bacteria contains a higher concentration of the acetate, then the growth of the bacteria will inhibit without inhibiting the central metabolism.
d). This is predicted because as E. coli-M bacteria grows, it starts secreting acetate. This is known as overflow mechanism. The regulatory interactions mediated by the acetyl-phosphate that plays an important role in the inhibiting growth by the acetate.
