Will earth run out of water?
While our globe may never run out of water as a whole, it's crucial to realize that pure freshwater isn't always available where and when humans require it. In fact, only six countries contain half of the world's freshwater. Over a billion people do not have access to adequate safe, clean water. Water scarcity will afflict the entire planet by 2040 unless water use is significantly decreased. "If we keep doing what we're doing now, there will be no water by 2040."

If your heart beats 70 times per minute, everyday of the year, how many times does it beat in a year?
Answer:
36,792,000
Explanation:
Using some math, if you say that it beats at 70 pm, then you should look for how much it beats in an hour, which is 4200 (60x70). Then you have to take that number and multiply by 24, which is 100,800. In a day it beats about that amount. Then you take that number and multiply by 365, which is 36,792,000.

how is dna copied in your own words?
Answer:
Replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. DNA replication is one of the most basic processes that occurs within a cell. Each time a cell divides, the two resulting daughter cells must contain exactly the same genetic information, or DNA, as the parent cell. To accomplish this, each strand of existing DNA acts as a template for replication.
Replication occurs in three major steps: the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment. During separation, the two strands of the DNA double helix uncoil at a specific location called the origin. Several enzymes and proteins then work together to prepare, or prime, the strands for duplication. Finally, a special enzyme called DNA polymerase organizes the assembly of the new DNA strands. The following description of this three-stage process applies generally to all cells, but specific variations within the process may occur depending on organism and cell type.
Answer:
website answer... the opening of the double helix and separation of the DNA strands, the priming of the template strand, and the assembly of the new DNA segment.
Explanation:

can someone please help me with these?
Answer:
C.) 2
Explanation:
Just a side note, I just assigned a random letter to work through this problem. It does not matter what you choose.
The carrier genotypes are Aa while any non carriers are AA, and any affected would be aa.
You would go through each of the pairs and do a pedegree to find out the genotypes of the offspring they produce. For 1 it would be a pedegree for Aa from the mom and AA from the dad. There offspring would be 1/2 Aa and 1/2 AA.
For number 2 it would be Aa for the mom and Aa for the dad. There offspring would be 1/4 AA, 1/2 Aa, and 1/4 aa.
For number 3 the mom would have AA and the dad would be aa. There offspring would be 4/4 Aa
For number 4 the mom would be Aa and the dad would be AA. There offspring would be 1/2 AA and 1/2 Aa.
Group #2 are the only set of parents that would produce a offspring that would be affected by the genetic condition, so the answer is C

What are Heterotrophs known as ?
Answer:
An organism that doesnt not produce its own food
Explanation:
Heterotrophs are consumers who eat other organisms for food, while autotrophs or producers make food by process of photosynthesis.
Answer:
A heterotroph is an organism that eats other plants or animals for energy and nutrients. The term stems from the Greek words hetero for “other” and trophe for “nourishment.”
Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs.
Heterotrophs are known as consumers because they consume producers or other consumers. Dogs, birds, fish, and humans are all examples of heterotrophs.
Heterotrophs occupy the second and third levels in a food chain, a sequence of organisms that provide energy and nutrients for other organisms. Each food chain consists of three trophic levels, which describe an organism’s role in an ecosystem. Occupying the first trophic level are autotrophs, such as plants and algae. Herbivores—organisms that eat plants—occupy the second level. Carnivores (organisms that eat meat) and omnivores (organisms that eat plants and meat) occupy the third level. Both primary (herbivores) and secondary (carnivores and omnivores) consumers are heterotrophs, while primary producers are autotrophs.
A third type of heterotrophic consumer is a detritivore. These organisms obtain food by feeding on the remains of plants and animals as well as fecal matter. Detritivores play an important role in maintaining a healthy ecosystem by recycling waste. Examples of detritivores include fungi, worms, and insects.

Answer: The correct answers should be the hares will multiply indiscriminately and destroy the ecosystem and the native herbivores will experience increased competition for resources.
Since the hares wouldn't have predators, and they are famous for rapid breeding, they would overpopulate the ecosystem. On the other hand, the native animals would have to compete with this population of hares for food and would have less for for themselves.

Explanation:
tuberculosis is an airborne disease if one is affected he or she can spread the disease especially in closed crowded areas.
symptoms are continuous coughing over a week,loss of weight
One autumn in the late 1990s, a number of people became ill after working at a single building at an industrial plant in a neighborhood of Baltimore, Maryland. Their symptoms ranged from simple coughing and other respiratory symptoms to pneumonia. At least one of the 70 people reporting symptoms died. He was 78 years old. The company voluntarily closed the building upon the recommendation of the Maryland Department of Health and Mental Hygiene. After all of the water systems at the plant were evaluated and disinfected, it re-opened and no new cases were reported.
1. Health departments often have less information than this when they start hypothesizing about the causative organism and its source. What is your first guess?
2. Describe the transmission characteristics of the suspected bacteria.
3. Is there a risk for a continuing community outbreak from these initial infections? Why or why not?
This disease is likely caused by a bacterium that was transported through the water. If water was infected only locally, likely, there are no outbreaks.
What can be guessed about the causative organism?The causative organism seems to be a type of bacteria in water. This is because disinfecting the water systems seemed to be the problem, which shows the source was there.
How are these bacteria transmitted?The suspected bacteria is transmitted through water. This seems to be the main transmission route because it seems workers experienced symptoms after drinking water.
Is there a risk for more outbreaks?If only the water of the plant was contaminated with this bacteria, it is likely there are no outbreaks. However, if contamination was general, outbreaks might appear.
