How and why does the epidermis produce new skin cells?
Answer:
About 95 percent of the skin cells in the epidermis are devoted to creating new skin cells in the lower two levels of the epidermis, which then cycle to the top layer to help form the stratum corneum. Eventually the dead cells of the stratum corneum flake off as new keratinocytes move up, and the cycle repeats itself.

8. Which example describes a consumer?
A. an organism that makes its own food
B. an organism that eats other organisms
C. an organism that breaks down dead material for food
Answer:
your answer is probably gonna be A
Answer:
B. An organism that eats other organisms
Explanation:
Scientists have been studying the size of three populations in a river in Ireland. In this ecosystem, pike (a type of big fish), and perch eat snails. The data showed that all three populations were stable. Then the snail population increased suddenly. What will likely happen to the size of the perch population as a result? The size of the perch population will...
Options:
A. Stay the same. The size of it's consumer population did not change, so the number of deaths in the perch population did not change. There will be the same number of births and deaths in the perch population.
B. Decrease. The larger snail population will take more energy storage molecules from the ecosystem, leaving fewer available for the perch population. This will lead to more deaths than births in the perch population.
C. Increase. The larger snail population will provide more energy storage molecules for the perch population, so they will reproduce more. This will lead to more births than deaths in the perch population.
D. Increase. An increase in any population within an ecosystem will lead to an increase in the sizes of all other populations in the ecosystem.
Answer:
C. Increase. The larger snail population will provide more energy storage molecules for the perch population, so they will reproduce more. This will lead to more births than deaths in the perch population.

what do you think are some human characteristics that reflect a common ancestry between non human primates and ourselves?
Explanation:
Primates are the mammalian order of organisms, having flexible hands and feet. These organisms have a developed brain and include organisms like lemurs, lorises, humans and apes. Humans are placental mammals, who have a highly developed brain.
Step 2 of 3
The evolutionary relationship between humans and non human primate can be studied based on the anatomical features and behavior that these two organisms share. The human characteristics that reflect a common ancestry between human and non-human primates are as follows:
1. The body hair are present on both the organisms.
2. Giving birth to young ones, after a long gestation period is common in both the organisms.
3. Different types of teeth which are incisor, canine, premolar and molars are present in both the organisms.
4. Both the organisms have the capability to regulate their thermal body temperature.
5. The brain size and capacity of both the organisms is large.
6. The capacity to learn and adapting to suitable behavior based on that is well present in both the organism.

Why do plants store their food?
Explanation:
Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.
Answer:
The main reasons being- survival, growth and reproduction

Excess postexercise oxygen consumption (EPOC) is also known as oxygen debt.
a. True
b. False
Answer:
True.
Explanation:
Excessive postexercise oxygen consumption can also be called oxygen deficit. It occurs after an individual completes a physical activity. Physical effort does not allow oxygen consumption to be normalized as soon as the body comes to rest and for this reason, the body begins to breathe and demand oxygen more intensely. This moment is known as excessive postexercise oxygen consumption, or oxygen debit. The intensity of breathing at this time will depend on the physical effort made, the weight loss and the increase in total caloric expenditure.

Explain the lac operon. How does it work when lactose is present and when lactose is not present. What about the presence of glucose?
Answer: The lac operon is an operon used to transport and metabolize lactose. In the presence of lactose, it functions as an inducer, it binds to the Lac I repressor protein and generate a conformational change that decreases its affinity for the operon region. Thus, the operon region is left free, the RNA polymerase can transcribe the structural genes.
Explanation:
An Operon is a group of structural genes whose expression is regulated by the same control elements and genes. The lac operon is an operon used to transport and metabolize lactose in Escherichia coli bacteria. Lactose is a disaccharide formed by the union of a glucose molecule and a galactose molecule (monomers). Upon breaking the glycosidic bond of lactose, both monomers are released and become available for use for energy. Remember that glucose is the main source of energy, and bacteria will always prefer to metabolize glucose rather than any other sugar, which they will only metabolize as an alternative energy source if glucose is not available.
The operon consists of several structural genes:
Lac z gene: encodes the enzyme β-galactosidase, which catalyzes the hydrolysis of lactose into glucose and galactose.Gene lac y: encodes the protein galactoside permease, for the transport of lactose into the bacterium.Promoter: region of DNA upstream of the above-mentioned genes that controls their expression, and where RNA polymerase binds to carry out gene transcription (synthesis of RNA from DNA that involves the expression of a gene).Operator: region of DNA located between the promoter and the beginning of the structural genes, which is recognized by the repressor protein Lac I.Repressor gene: encodes the Lac I repressor protein, which binds to the operator region and thus prevents transcription of genes under the control of this promoter. When the repressor is removed from the operator (in the presence of inducer which is lactose), RNA polymerase is ready to bind and start transcription.So, the lac operon is under a type of negative regulation, where genes can always be transcribed, except when the Lac I repressor protein is bound to the operator region. The promoter of the lac I gene is constitutive, so the Lac I protein is permanently expressed and remains bound to the operator, preventing the transcription of structural genes. That is, preventing the action of the lac operon in the absence of lactose. However, in the presence of lactose, it functions as an inducer of the operon. It is able to bind to the Lac I repressor protein and generate a conformational change that decreases its affinity for the operon region. Thus, the operon region is left free, the RNA polymerase can freely transcribe the structural genes, the enzyme β-galactosidase is synthesized which can degrade lactose to glucose plus galactose (and thus metabolize the lactose in the medium).
It should be clarified that in reality, the true inducing molecule of the lac operon is allolactose, an isomer of lactose obtained by a transglycosylation occasionally carried out by β-galactosidase. But usually to simplify terms, lactose is referred to as the inducer.
So, the lac operon is always inactive unless there is lactose in the medium. As mentioned, E. coli prefers glucose, so the lac operon will not be activated in the presence of lactose if glucose is present in the medium. If both glucose and lactose are present in the medium, the repressor is inactivated, so the operon is transcribed but at a basal (low) level due to the presence of glucose.
Watch this video about a river that China is building. Explain how the river will help prevent the negative effects of drought. In your answer, explain any negative effects that you foresee this new river will have on the people or on natural habitats.
Answer: The river will increase Beijing’s water supply, which is currently at risk of not meeting the city’s needs. This increase will help to soften the effect of droughts.
The downside of the new river is that it may disrupt natural areas, including habitats for plants and animals. The project will also be expensive and may take up space that could be used for homes, businesses, or agriculture.
Explanation: Change the wording...
The construction of a new river can help prevent the negative effects of drought by increasing the availability of water for human and ecological needs, and one way that a new river can help prevent the negative effects of drought is by increasing the recharge of groundwater resources.
What is a drought?During periods of drought, water resources can become scarce, leading to reduced crop yields, drinking water shortages, and negative impacts on ecosystems. By providing a new source of water, a new river can help alleviate some of these negative effects. A new river can provide a source of water that can help recharge aquifers and replenish groundwater supplies. However, the construction of a new river can also have negative effects on people and natural habitats. One potential negative impact is the displacement of people living in the area where the river is being constructed. This can lead to the loss of homes, farms, and livelihoods for local communities.
Hence, the construction of a new river can help prevent the negative effects of drought by increasing the availability of water for human and ecological needs.
