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.

Definition for isotope. (Science).
Answer:
One or more number of species which have same number of atomic number but different mass number called isotopes
Explanation:
Answer:
Check explanation below!
Explanation:
Concepts
Isotopes are atoms with a different amount of neutrons. Atoms will ALWAYS have a set number of protons. On the periodic table, you may notice that the atomic mass is a decimal. This is mainly because neutrons often mass different amounts, so scientists calculate the average mass of it to find the atomic mass of the atom. Isotopes are still the same atom; they just have unique amount of neutrons.

The five stages of design thinking are:
Empathize—research your users' needs.Define—state your users' needs and problems.Ideate—challenge assumptions and create ideas.Prototype—start to create solutions.Test—try your solutions out.What is design thinking?Design thinking is a methodology that provides a solution-based approach to solving problems.
The first stage of the design thinking process allows us to gain an empathic understanding of the problem we are trying to solve. Individual will consult experts to find out more about the area of concern, and conduct observations to engage and empathize with our users.
In 2nd stage, we should always seek to define the problem statement in a human centered manner as you do this.
In 3rd stage, we need to look for alternative ways to view the problem and identify innovative solutions to the problem statement we’ve created.
In 4th stage, the aim is to identify the best possible solution for each of the problems identified during the first three stages.
In final 5th stage, ultimate goal is to derive as deep an understanding of the product and its users as possible.

Answer:
Answer my recent question
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.

9. Briefly describe the four types of tissue.
Answer:
These are the four tissues: connective tissue, epithelial tissue, muscle tissue, and nervous tissue.
Connective tissue supports other tissues and binds them together (bone, blood, and lymph tissues). Epithelial tissue provides a covering (skin, the linings of the various passages inside the body). Muscle tissue includes striated (also called voluntary) muscles that move the skeleton, and smooth muscle, such as the muscles that surround the stomach. Nerve tissue is made up of nerve cells (neurons) and is used to carry "messages" to and from various parts of the body.

Explain how parts of a whole system contribute to the function of a whole system?
Organ systems are made up of parts that contribute to the functions of the whole system.
How do parts contribute to the functioning of the whole system?The human body system is made up of parts that work together to carry out certain functions. For example, the integumentary system conducts the function of protecting the body and consists of skin, hair and nails that integrate together to make the whole system.
The immune system an other example of the same that is made up of intricate organs, tissues and cells like the White blood cells that come together to carry out the function of keeping infections at bay.
Two or more body systems also work together to perform a particular function. Like the respiratory and circulatory systems join to provide oxygen to the cells and give out carbon dioxide.
