two models of sells are shown below. Why would model b be better for moving nutrients in and out of the cell?

Answers

Answer 1

Answer:

The correct answer is - C. It has a larger ratio of surface area to volume.

Explanation:

In cell B, the ratio of surface area to volume is larger in comparison to cell A. The surface area to volume ratio can be understood as it is the size of surface area that the volume of a particular substance can move in or out of the cell, in a unit of time.

Thus the larger the ratio of surface area to volume faster the diffusion rate of nutrients will be as the surface area is a square measurement and volume is cubed so the surface area increases faster than volume.

Answers

Answer:

decreasing the number of copies of the polypeptide translated from this mRNA

Explanation:

Polyadenylation refers to the addition of multiple adenosine monophosphates (i.e., a polyA tail) to an RNA molecule, usually a messenger RNA (mRNA). Polyadenylation is catalyzed by an RNA polymerase called poly(A) polymerase (PAP), which adds adenine nucleotides to the mRNA. In eukaryotic cells, polyadenylation is required to produce a mature mRNA which is then used as template for protein synthesis during translation. This posttranscriptional modification (polyadenylation) is known to stabilize the mRNA by preventing its degradation by exoribonucleases, i.e., enzymes that degrade RNA molecules by removing terminal nucleotides from 3' and 5' ends. In consequence, it is expected that a mutation that prevents polyadenylation of a target mRNA decrease the number of copies of the protein translated from this mRNA.

Scientists have determined that Earth's interior has layers with different properties. One property is that the inner core is solid. Which of the following statements can be used as evidence to support this property?

Answers

Answer:

Earth's inner core is the innermost geologic layer of the planet Earth. It is primarily a solid ball with a radius of about 1,220 km (760 mi), which is about 20% of Earth's radius or 70% of the Moon's radius.[1][2]

The internal structure of Earth

There are no samples of Earth's core accessible for direct measurement, as there are for Earth's mantle. Information about Earth's core mostly comes from analysis of seismic waves and Earth's magnetic field.[3] The inner core is believed to be composed of an iron–nickel alloy with some other elements. The temperature at the inner core's surface is estimated to be approximately 5,700 K (5,430 °C; 9,800 °F), which is about the temperature at the surface of the Sun.[4]

Answer:

I think the answer is J: desert.

Explanation:

In the grassland, rainforest, and swamp, it either rains frequently or is constantly surrounded by water. However, deserts rarely get any water. Also, not many desert plants have leaves, but instead have very large stems, like cacti and large sage bushes. Therefore, the desert would be the most important habitat this could take place.

The answer is J the desert. This mechanism is used to draw out long periods of time since the desert doesn’t receive as much rain as any other ecosystem.

Why can't weeds take over the world? In other words, what limits the growth of populations?

Answers

Answer and Explanation:

Many elements can limit population growth. The main elements that can cause this are the lack of resources necessary for the life and development of living beings and the lack of space to be taken by them. In relation to weeds, these resources can be the availability of sun, amount of soil, soil fertility, availability of water and space. However, these plants are very resistant to the lack of these resources, and what most limits their growth is human interference.

Weeds are unfavorable to agriculture and other human activities. This makes humans fight the population growth of these plants using chemical products and even physical strategies. This interference prevents weeds from taking over the world.

Which of the following is true about the coasts of North and South America? O A. Little industry is located along the coasts, B. There are few cities and the population is sparse. O c. A majority of the population is located there. D. People go to the coasts only when on vacation,

Answers

Answer:

The correct answer is C. In North and South America, a majority of the population is located on the coasts.

Explanation:

Historically, the vast majority of civilizations have sought to establish their urban centers around bodies of water, be they rivers or seas, that allow them a rapid expansion outward as well as channels through which to channel trade. Thus, it can be seen how throughout the world and especially the American continent, large cities and population centers are located primarily on the coasts. Examples of this situation are Vancouver in Canada, New York and Los Angeles in the United States, Rio de Janeiro in Brazil or Buenos Aires in Argentina.

WILL GIVE 90 POINTS AND BRAINIEST PLEASE HELP Read the speech "Voluntourism: An Opportunity Too Good to be True" and consider the advertisement "The Opportunity of a Lifetime." Then, answer the question. Voluntourism: An Opportunity Too Good to be True A Speech to the Student Body of Evergreen High [1] Picture this: It's Spring Break, and you fly off to some country where there's lush rainforests and beautiful, blue coastlines to explore. There's also people in need, so you decide to blend your vacation with volunteering. Volunteering as a tourist, or voluntourism, seems like a great way to explore new regions and help people at the same time. However, this "volunteer plus travel" experience can actually harm local communities. While many teens might view traveling and volunteering abroad as a worthwhile adventure, there are more genuine and effective ways to make a difference. [2] Most would agree that volunteering in general is a worthy use of time. However, what if you found out the children you are "helping" are actually being kept in poor conditions so voluntourists will spend money to come to the local area? Dale Rolfe, a supporter of ethical voluntourism, explains the shocking reality that "Animal sanctuaries and orphanages are often manufactured for the voluntourist...encouraging a cycle of exploiting the very animals and children the volunteers are trying to help." [3] Proponents of the "volunteer plus travel" experience also argue that traveling to new places builds character and is a valuable way to learn about different cultures. With voluntourism, however, participants often pursue experiences that are all about them. For example, they sign up to build a school for a gold star on their resume, but they have no real building skills and take jobs away from local construction workers (Schulten). Or, they arrive to teach English but instead take selfies with the locals. One world traveler and ethical voluntourist believes voluntourism "can perpetuate small minded views of the world by taking insulated, fake, and structured experiences and selling them as unabridged and eye opening" (Carlos). The voluntour experience is a mirage. The voluntourist's eyes are not opened to real life at the destination, and lasting change is not achieved. [4] If you want a genuine experience where you can see a lasting impact, there are better options than voluntourism. You can volunteer in your local community. Give an hour every week to your town's animal rescue. Serve monthly dinners to the homeless. Be a reliable, positive influence on a child who needs a mentor. Studies show that volunteering and forming lasting relationships with those you help has a positive impact on your physical and emotional health. In fact, blood pressure is reduced, memory is improved, and rates of depression are reduced (Michaels). [5] There is another reason to look into alternatives to voluntourism. Did you know the average "voluntour" travel package costs $3,400 (Rolfe)? Could that travel money be better spent? If the world's citizens are your passion, it could go to an international organization. If you care about education, your funds can be used to buy books for students in faraway lands. If you want villagers to have clean water, contribute funds to local efforts to dig wells. If you want to experience a different culture, travel to the country as a guest, and learn from the locals how you can best help them after you've returned home. But do not voluntour. [6] In reality, there are better ways to make a difference. Voluntourism might appear to be an adventure that blends travel and helping others, but it does little except provide a costly, superficial experience that might actually do more harm than good. So, volunteer where you are most needed-at home, where you can stay to see the job through and form genuine, lasting relationships. Choose a beautiful coastline closer to home and send the travel money you saved to an international organization that will put it to good use. Whatever you do, don't turn someone else's hardship into your vacation.
