How do populations and communities interact?
Answer:
An ecological community is made up of all the populations of all the different species that live together in a particular area. The interactions between different species in a community are called interspecific interactions, inter- means "between".
A 1500 kg car sits on top of a car carrier truck 2.5 meters above the ground how much potential energy does the car have
Answer:
36,787.5 Joules
Explanation:
Potential Energy = mass * acceleration due to gravity * height
U = mgh
We know the following:
mass = m = 1,500 kg
acceleration due to gravity = g = 9.81 m/[tex]s^{2}[/tex]
height = h = 2.5 m
When we substitute each value into the formula we get the following:
U = 1,500 kg * 9.81 m/[tex]s^{2}[/tex] * 2.5 m = 36787.5 kg[tex]\frac{m^{2}}{s^{2} }[/tex] = 36,787.5 Joules
Southern California and Arizona have the same latitude. Arizona summers are hot while Southern California summers are mild. Why?
a.] The cool pacific current flows down from Alaska keeping Arizona mild. California is too far away from the ocean and has little effect.
b.]The warm pacific current flows down from Alaska keeping California mild. Arizona is too far away from the ocean and has little effect.
c.]none of these choices
d.]The cool pacific current flows down from Alaska keeping California mild. Arizona is too far away from the ocean and has little effect.
Answer:
the answer would be D
Explanation:
This is because Cool air goes into southern California, making the summers cooler.

Why does the body respond to stimuli
Answer:
That is because of Receptors. Receptors are groups of specialised cells. They detect a change in the environment stimulus. In the nervous system this leads to an electrical impulse being made in response to the stimulus.
Hope this helped
All the best !!
The body typically responds to stimuli because of the function of the receptors.
How does the body of an organism respond to stimuli?The organism significantly responds to the stimuli by means of a number of effectors, such as muscles and glands. Energy is generally used in the process in order to facilitate an ideal function of the entire body and maintain homeostasis.
Due to this, the organisms change their behavior in response to changes in the surrounding environment. For example, an organism may move in response to its environment.
The process of responding to stimuli is generally mediated by the receptors which are the groups of specialized cells within the body. These receptors alter their physiology and function with respect to the surrounding environment and detect a change. In the nervous system, this directs to an electrical impulse being made in response to the stimulus through a chemical process.
Therefore, the body typically responds to stimuli because of the function of the receptors.

A DNA sample is anyalyzed and you find that 22% is cytosine. How much thymine would be in the same cell?
Answer:
28% Thymine
Explanation:
DNA molecule is made up of four nucleotides namely: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G). These nucleotides make up the DNA molecule unevenly, however, according to Chargaff in his rule, he stated that the amount of Adenine&Thymine, Guanine& Cytosine in a DNA must be equal, which must all equate to 100% i.e. (A = T) + (G = C) = 100%
Based on this Chargaff's rule, if a DNA sample is analyzed and found to contain 22% of cytosine. This means that the amount of Guanine in that DNA sample must also be 22%.
Therefore; 22% C + 22% G = 44%
100 - 44 = 56%. This means that Adenine and Thymine will share this 56% among each other i.e. 56/2 = 28% Adenine and 28% Thymine.
which product is made from a renewable resource?
A. a penny made with copper?
B. computer chips made from silicon?

D. earrings made from silver?
Answer:
C. A pie made with blueberries
Explanation:
Blueberries can be grown naturally, so they are a renewable resource.
Blueberries are renewable resources. Hence, option C is correct.
What are renewable resources?Renewable resources are those natural resources that continue to exist even after their consumption. They are also known as flow resources.
Renewable resources include plants, biomass, ocean currents, energy, wind, solar energy, tides, waves, etc. All these things will continue to exist even after their consumption. They can be used repeatedly and do not run out.
Advantages of renewable resources:
They are cheap.They are easily available.They are eco-friendly.They are clean and efficient.Copper, silicon, and silvers are minerals and non-renewable resources, and blueberries are plant products and hence, they are renewable resources. Therefore, option C is correct.

No.
Explanation:
The factors of an experiment is considered as independent because it does not change or not dependent on other while on the other hand, the data is the dependent variable due to its dependency on the treatments. No, people will not pick up a dollar bill which is dropped on the floor in the airport during a pandemic because they can't put their life in danger for a dollar.

Explanation:
Considering that a hydrophilic stain was used to stain the skin, explain why the fat vacuoles in adipocytes are white (Hint: Remember hydrophilic will color those areas that "like water", think about water`s relationship with fats).
Answer:
The hydrophilic nature of the stain explains that these molecules are polar and charge molecules. therefore, attracts the water molecule but due to their polar nature, it will avoid lipid or fat molecules.
Adipocytes are the cells that are made up of fat or lipids that are hydrophobic due to their non-polar nature and due to this fact, these hydrophilic stains will not be able to stain adipocytes and will not be colored by the stain.

Which of the formed elements arise from myeloid stem cells?
a) B cells
b) natural killer cells
c) platelets
d) all of the above
Answer:
c
Explanation:
it creates platelets and a myeloblast, or monocytes
The formed elements that may arise from myeloid stem cells are platelets. Thus, the correct option is C.
How myeloid progenitor cells are formed?The myeloid progenitor cells are formed from the hematopoietic stem cells which are of multipotent nature. Such HSC cells induce the transcription factor GATA-2 and give rise to myeloid progenitor cells.
The process of hematopoiesis occurs in the bone marrow in which HSCs play a major role in synthesizing the blood cells.
The myeloid progenitor cell further produces dendritic cells through the transcription factor FLT3L, eosinophils through IL-5, mast cell, platelets through thrombopoietin, RBCs through erythropoietin, etc.
Therefore, among the given options, platelets are derived from myeloid stem cells. Thus, the correct option is C.

What can the result be if DNA replication does not occur without errors?
A. No genetic diversity
B. It has not been researched enough yet to know
C. A perfect, mutation-free society
Answer:
C. A perfect, mutation-free society
Explanation:
Mutation is a genetic phenomenon involving the alteration or change in the genetic sequence of a gene. Mutation is commonly caused by mutagens (chemical substances that induce mutation), DNA replication mistakes or errors etc.
According to this question, if DNA replication occurs without error, this means that mutation will likely not occur, leading to a perfect, mutation-free society.
An individual has the genotype Aa Bb CC Dd ee FF. How many different types of gametes could it produce in terms of unique allelic combinations of these genes?
Answer:
64
Explanation:
The individual in this question with genotype: Aa Bb CC Dd ee FF has six (6) different traits encoded by six (6) genes. The diploid number of the organism in this question is 12, however, the number of possible allelic combinations in each gamete can be calculated by using 2^n where n = haploid number of chromosome or number of allele that can be in one gamete.
Using this simple formula, 6 possible alleles can be in the gamete of this organism with the above genotype, hence, the individual can produce 2^6 = 64 different types of gametes in terms of unique allelic combinations of these 6 genes.
