Yes, energy can be harvested by cells from glucose without oxygen through a process called anaerobic respiration.
In anaerobic respiration, glucose is broken down into two molecules of pyruvate, which then undergo a series of reactions that generate energy in the form of ATP. Unlike aerobic respiration, which requires oxygen as the final electron acceptor, anaerobic respiration uses other electron acceptors such as nitrate or sulfate. However, the energy yield from anaerobic respiration is lower than that of aerobic respiration, and it also generates lactic acid or alcohol as byproducts.
Anaerobic respiration produces much less energy than aerobic respiration, since it only yields two ATP molecules per glucose molecule, compared to 36-38 ATP molecules in aerobic respiration. However, it is still an important process for some organisms that live in environments with low oxygen, such as certain bacteria, fungi, and animal cells. It is also responsible for the production of lactic acid in muscle cells during intense exercise, which can cause muscle fatigue and soreness.
Hence, the correct option is A.

which era characterized by the extinction of reptiles and the appearance of mammals is considered significant in geological history
Answer:
Mesozoic Era
Explanation:
The "Mesozoic Era" is divided into three periods: Triassic, Jurassic and Cretaceous. During the last period (Cretaceous), which was considered the longest, the extinction of reptiles occurred and the new mammals appeared. This event was also known as the "Cretaceous-Paleogene Extinction Event." Around 3/4 of plants and animals died. Such event became significant boundary that laid between the Cenozoic Era and the Mesozoic Era. This made it significant in geologic history.

The fox population in a certain region has an annual growth rate of 5 percent per year. It is estimated that the population in the year 2000 was 23500 . (a) Find a function in the form \( P(t)=a b^{t}
The fox population can be modeled using an exponential growth function of the form P(t) = ab^t, where P(t) represents the population at time t, a is the initial population, b is the growth factor, and t represents the number of years.
In this case, the population in the year 2000 was given as 23500. We can use this information to find the values of a and b in the exponential growth function. Since the population has an annual growth rate of 5 percent, the growth factor (b) would be 1 + growth rate = 1 + 0.05 = 1.05.
To find the value of a, we substitute the given population value for the year 2000 into the exponential growth function: P(0) = ab^0 = a(1.05)^0 = a. Therefore, a = 23500.
Now we have the values of a and b, and the exponential growth function for the fox population becomes P(t) = 23500 * (1.05)^t, where t represents the number of years since the year 2000.
This function can be used to estimate the fox population for any given year after 2000 by substituting the desired value of t into the equation.

How is the epithelium suited for the substances ?
Answer:
Epithelial tissue is composed of cells laid together in sheets with the cells tightly connected to one another. Epithelial layers are avascular, but innervated.
Epithelial cells have two surfaces that differ in both structure and function.
The epithelial cells are nourished by substances diffusing from blood vessels in the underlying connective tissue. One side of the epithelial cell is oriented towards the surface of the tissue, body cavity, or external environment and the other surface is joined to a basement membrane. The basement layer is non-cellular in nature and helps to cement the epithelial tissue to the underlying structures.

gray is dominant to silver in barracuda. if a silver barracuda and a heterozygous gray barracuda across, what percentage of the offspring will be gray? O 50% O 1005 0 25% O 75% Question 11 disease marries woman the Huntington's disease is inherited as an autosomal dominant trait that is lethal in the homozygous dominant condition in embryos. If a man with Hunting disease. What is the probability that they will have a daughter with the Huntington gene genotypically normal the O 1/4 O 1/2 none of the choices is correct O 3/4
When they cross, the possible combinations of alleles in their offspring are: GG (gray), Gg (gray), and gg (silver). Therefore, 50% of the offspring will be gray (either GG or Gg).
For the first question, since gray is dominant over silver, the heterozygous gray barracuda will have one allele for gray (G) and one allele for silver (g), while the silver barracuda will have two alleles for silver (gg).
For the second question, if a man with Huntington's disease (HD) marries a woman who is genotypically normal (not a carrier of the HD gene), the man must have at least one dominant HD allele (H) and one recessive normal allele (h), while the woman must have two recessive normal alleles (hh). The possible combinations of alleles in their offspring are: Hh (carrier of HD, but not affected), and hh (normal). Therefore, the probability of having a daughter who is genotypically normal (hh) is 50% or 1/2.

Describe why is it important to pursue solar energy
conversion systems?
Answer:
Explanation:
Take Advantage of the Solar Power Benefits
Apart from the obvious financial benefits, there are other pertinent reasons why you should convert to using solar power instead of fossil fuels.
What other reasons should you consider when going solar? Here are seven compelling reasons.
1. Solar Power Is Good for the Environment
The most commonly known fact about solar energy is that it represents a clean, green source of energy. Solar power is a great way to reduce your carbon footprint. There’s nothing about solar power that pollutes mother nature. Solar power doesn’t release any greenhouse gasses, and except for needing a source of clean water to function, it uses absolutely no other resources. Hence, it’s safe and environmentally-friendly. Yet, people are still in doubt why solar energy is good.
Solar power is self-sufficient and installing solar panels on your roof is a safe and easy path to contribute to a sustainable future. Starting on your home is a great way to show you care about the environment.
2. Solar Electricity Makes Your Home Go Off-the-Grid
The decrease in the cost of solar panels serves as a great example of why there should be an increase in the use of solar energy. Traditional electricity relies heavily on fossil fuels such as coal and natural gas. Not only are they bad for the environment, but they are also limited resources. This translates into a volatile market, in which energy prices alter throughout the day.
Solar electricity boosts your electricity independence! By investing in a 4kW solar system, which is the most common domestic size, you can easily protect yourself against unpredictable increases in utility prices, and enjoy cheap electricity throughout the entire day – the sun will never increase its rates and it gives you energy security.
Once you have solar panels up on your roof, you’ve technically reached an energy-independent status. Solar battery storage systems can also help store electricity for nighttime and rainy days.
3. Solar Power Can Use Underutilised Land
You may continue to wonder why solar power. With the increasing need of solar energy, it’s become easily accessible to most of us. Across countries, there are vast land that are far away from big cities or capitals, and are not used for anything at all.
With solar power, we can actually make use of the land and subsequently generate great value; solar energy provides a source of power for everyone. In this way, we don’t need to use high priced land that might be better suited for other applications.
You might have heard of solar farms – panels used to harvest solar energy in large numbers. This highlights perfectly how solar power makes use of underutilised land. For instance, a 45 acre solar farm has been recently built in the UK, and it’s able to power 2,500 homes.
4. Solar Power Causes Less Electricity Loss
Electricity needs to be transported from big power plants to end-consumers via extensive networks. Long distance transmissions equal power losses. Ever wondered what are solar panels used for? They’re on your roof to get energy from the sun. Rooftop solar power is helpful in increasing electricity efficiency, considering the short distance. Your energy becomes domestic and as a result you’re in control of your own bills and energy usage. Furthermore, solar power systems are durable, thus chances of service interruption are reduced.
5. Solar Power Improves Grid Security
When there are many of us switching to solar power, we are less likely to experience blackouts or brownouts. Every household in the UK that have solar cells installed, functions as a small power plant. This, in turn, provides us with a greater electricity grid security, especially in terms of natural or human-caused disasters.
With the help of solar panel grants, you can also be paid to export electricity back to the grid.
Solar Power Makes Use of Underutilised Land
6. Solar Power Creates Jobs and Economic Growth in the UK
Our national economy can be helped by solar power. The more people who opt for solar, the more needs will be for companies to install solar panels. This creates additional jobs for skilled workers, and consequently keeps the economy growing.
In 2015, for instance, the UK become the second-largest solar employer, with 35,000 people, and the continent’s largest solar photovoltaic (PV) panel installation market.
7. Solar Power Is A Free Source of Energy
The sun provides us with more energy than we could ever use, and no one can monopolise the sunlight. Your solar power system will start saving money from the moment it’s turned on, however, the advantages of solar power are best visible in the long-term. The longer you have your solar power system, the more you enjoy the benefits of solar technology and support the environment.
