A. Fats have been digested by salivary amylase.
B. Large proteins have been broken down into smaller proteins.
C. The food has become acidic and is in smaller pieces.
D. The starches have been partially broken down.
Answer:
D. The starches have been partially broken down.
Explanation:
Your saliva has salivary amylase, an enzyme that breaks down starch into smaller glucose monomers. Thus, by the food reaches your tummy, some of the starch has been broken down. Protein and fats are primarly broken in stomach and food also becomes acidic in stomach.

Assume that r max is 1.0 and the carrying capacity is 2,000. calculate the population growth rate when n= 2,100 and when n = 2.500 individuals.
Answer:
Given:rmax = 1.0carrying capacity = k = 2000N = 2100N = 2500dN/dt =popu
Explanation:
The population growth rate when n = 2100 and when n = 2500 individuals is - 0.25 and for n = 2100 individuals , it is - 0.05 .
What is population growth rate ?Population growth rate is the rate at which a population increases in size over a specific period of time, usually expressed as a percentage.
It is calculated by subtracting the number of deaths and emigrations from the number of births and immigrations, and then dividing this figure by the total population at the start of the period.
The logistic growth model can be used to calculate the population growth rate at a given population size (n) using the following equation:
r = r_max * ((K - n) / K)
where:
r = population growth rate
r_max = maximum per capita growth rate
K = carrying capacity
n = population size
Given r_max = 1.0 and K = 2,000, we can calculate the population growth rate for n = 2,100 and n = 2,500 as follows:
For n = 2,100:
r = 1.0 * ((2,000 - 2,100) / 2,000)
r = 1.0 * (-0.05)
r = -0.05
Therefore, when the population size is 2,100 individuals, the population growth rate is -0.05, indicating that the population is decreasing in size.
For n = 2,500:
r = 1.0 * ((2,000 - 2,500) / 2,000)
r = 1.0 * (-0.25)
r = -0.25
Therefore, when the population size is 2,500 individuals, the population growth rate is -0.25, indicating that the population is decreasing at a faster rate than when the population size was 2,100 individuals.

A diploid strain of yeast that was trisomic for a chromosome carrying the Trp1 gene was sporulated. When the asci were dissected and tested for the ability to grow without tryptophan, some asci had 4 prototrophic spores and some asci had 2 prototrophic spores and 2 auxotrophic spores. What was the genotype of the diploid trisomic parental strain with respect to the Trp1 gene?
Answer: Prototrophs are strains that have the same dietary requirements as their parents. Auxotrophs are mutants that require more nutrients in their media to develope.

Temperature differences between
seasons can be beneficial to the
organisms in lakes and ponds.
Which of these is a benefit of
seasonal temperature
differences?
A. separates where certain fish can live
B. causes all vegetation to freeze
C. removes all terrestrial life
Answer:a
Explanation:
The benefit of seasonal temperature is separates where certain fish can live.
What is temperature?Average temperatures rise year-round as a result of global warming (see the U.S. and Global Temperature indicator), while some seasons may experience greater rises than others.
Winter is especially susceptible to temperature increases. Overall, minimum temperatures have risen faster than maximum temperatures on average.
Thus, a large portion of the observed warming in the United States has occurred during the winter, during the night, and in the northern regions of the country—when and where it is typically the coldest.
Even while the United States has had numerous winters with extraordinarily low temperatures, these winters have grown less frequent overall.
Therefore, The benefit of seasonal temperature is separates where certain fish can live.

How to collect fingerprints at a crime scene?1. Investigate: Click on different parts of the crime lab to look for other visible prints. (Hint: There are a total of two visible prints.) To see which parts of the lab you can see up close, select Show all locations. Photograph and categorize every print you come across.
2. Notice: After locating the two visible prints, a duster will appear in the upper right corner. The duster distributes fingerprint powder, which adheres to the skin oils that comprise latent prints and allows them to be seen. Drag the duster into the lab to dust for prints.
Repeat your search of the room. When you find a latent print, drag the roll of tape over it to collect it. (Latent prints are collected with tape that adheres to fingerprint powder.) Gather and categorize the three remaining prints.

Part C. These Beatles have a uniform distribution. And you’re one how many Beatles are there per hectare? How many Beatles per hectare you were there in the year the Beatles Rich carrying capacity? Round up or down to the nearest whole number if necessary
In year 1, the population was 11,500 spread over 115 hectares.
What is carrying capacity?Carrying capacity referred to as a specie's average population size in a particular habitat. The species population size is limited by environmental factors like adequate food, shelter, water. If these needs are not met, the population will decrease until the resource rebounds.
The number of beetles per hectare is 11,500/115= 100 beetles.
By year six, when the beetles reached the carrying capacity, the number of beetles per hectare is 14,677/115 = 128 beetles.

Some people worry that the increasing number of cell phones will cause cancer because of the energy of the radio waves they emit. Cell phones are a new technology that only recently became widely used. And because cancer takes years to develop, the amount of risk is not yet known.
summarize what’s known so far. In your summary, include information about the energy of radio waves. Be sure to only use credible sources. Based on what you learned from your research, do you think people should limit their cell phone use? Why or why not?
Answer:
Cell phones emit radiofrequency energy, a form of non-ionizing electromagnetic radiation, which can be absorbed by tissues close to the phone. The amount of radiofrequency energy a person is exposed to depends on the frequency of the signal and the amount of time they spend on the phone. The Federal Communications Commission (FCC), the International Agency for Research on Cancer (IARC), and the American Cancer Society (ACS) all agree that more research is needed to determine the possible health effects of cell phone use. So far, there is no scientific evidence that proves that cell phone use causes cancer. Some studies have suggested a possible link between cell phone use and cancer, but more research is needed to confirm these results. The ACS does not recommend limiting cell phone use because the risk of cancer is still unknown.
Hope this helps!
Explanation:
Answer:
If people are scared because phones cause cancer because of the radio waves why aren't they scared of laptops/computers/pc, TVs, and even tablets all of these are the same thing but bigger so why is it okay to not be scared to get cancer from these items? I think if we stop using our phones as much it will be good because not only will kids and teenagers touch grass more but they will be able to explore things they never knew existed. In my opinion, we should stop using all electronic a lot because they all probably do end up causing cancer and other issues in the future.
