A certain stem cell produces only muscle cells. What kind of stem cell is this?
A. Pluripotent
B. Unipotent
C. Totipotent
D. Multipotent
the answer is (B. Unipotent)
Answer:
B) unipotent
Explanation:
Unipotent stem cells come from multipotent stem cells which can only become a few different cell types. Unipotent stem cells can be programmed to be only a specific cell type. They will only follow that one genetic path, thus the name "uni".
Based on the graph, which of these conclusions is correct? (2 points)
a
Heat is not added in portions BC and DE.
b
Heat is not added in portions AB and CD.
c
Change of state takes place in portions BC and DE.
d
Change of state takes place in portions AB and CD.
Answer:
The answer is "Option c".
Explanation:
Throughout the given question, Option c is acceptable which is based on the graph. The status of parts BC and DE are significantly changed because the temperature in the parts BC (0 degrees Celcius) & DE (100 degrees Celcius) is relatively stable to only the template would also have changed from ice and water into the vapor.
An object is placed at 0 on a number line. It moves 3 units to the right, then 4 units to the left, and then 6 units to the right. What is the displacement of the object?
Answer:
5
Explanation:
Distance is how far something goes and Displacement is how far it is from 0 or from the starting point. Additionally, displacement is a vector so it has a direction, in this case, left or right. To make this shorter let's just find displacement. So you're at 0 and you go 3 units to the right and so you're at positive 3 on the line. Next, you move 4 units to the left so now you're at -1. Finally, you move 6 units to the right and now you're at postive 5. Now you're +5 units away from 0 and so +5 is your displacement (5 units to the right is also correct)
Answer: +5 units or 5 units to the right (as long as it has a sign or a direction it's correct)

Some species form social groups only with members of the same gender. For example, elephants form groups with only females and their offspring. Once the male offspring reach a certain age, they leave the group and become solitary.
Which is a benefit of this type of social group structure?
Females do not have to compete for a mate.
Male offspring can belong to more than one social group.
Adult males can mate with females in several different social groups.
Females are the only ones responsible for taking care of the offspring.
Answer:
Females do not have to compete for a mate.
Explanation:
Due to grouping of animals, females do not have to compete for a mate because each group has its own male. They have a male with which she mate and produce fertile offspring and has a complete family so we can say that the benefit of such type of social group structures is that females do not have to compete for a mate in the population as compared to other animals.
Answer:
A. female's do not have to compete for mates.

The density of a white dwarf is
Answer:
The density of a white dwarf is 1 x 109 kg/m3.
Explanation:
A typical white dwarf is half as massive as the Sun, yet only slightly bigger than Earth. An Earth-sized white dwarf has a density of 1 x 109 kg/m3. Earth itself has an average density of only 5.4 x 103 kg/m3. That means a white dwarf is 200,000 times as dense.
1 x 10⁹ kg/m³ is the density of white dwarf. It is 200000 times denser than Earth. And it is the second densest object we know after neutron star.

2000
Lions
100,000
47,000
Cheetahs
50,000
7,500
Zebras
15,000
2,500
Which explanation is best supported by the numbers in the chart?
Answer:
Population of lions are more than cheetahs and zebras.
Explanation:
The chart provides information about the population sizes of Lions, Cheetah and Zebras. According to this information, population of lions is the greatest as compared to Cheetah and Zebras. This is due to suitable conditions for the lions such as food and shelter etc in that jungle of Africa as well as strong competitor and its aggressive behaviour make them successfully survive and increase its population in the jungle.

Which product forms from the reaction between nitrogen (N)
(CI)?
A. NCI
B. NCI
C. N2CI
O D. N2C1
Answer:
None of the above
Explanation:
Because as N has the valence of 3 when it reacts with Cl of 1 as valence they will form NCl3Answer:
The product of the reaction between nitrogen (N) and (CL) is nitrogen trichloride (NCl3)
Explanation:
Although by seeing the question's answer choices, I think it was an error to detect the question (image) by Brainly as 2 of the answers is written the same.
However, when nitrogen gas reacts with chlorine gas, the product is gaseous nitrogen trichloride (NCL3), I guess 1 of your answer must be NCL3.

1) What is the control group? 2) What is the experimental group? 3) What is the independent (manipulated) variable? 4) What is the dependent (responding) variable? 5) What should Tina's conclusion be?
Complete question:
Tina asks the question “Does caffeine increase the heart rate of an earthworm?” In Test 1, she measures the heart rate by looking at the earthworm under a microscopes, the earthworm has a heart rate of 50 bpm (beats per minute). In Test 2, she places a few drops of caffeine on the earthworm’s skin and measures the rate again. In this test, the heart rate is 68 bpm.
1) What is the control group?
2) What is the experimental group?
3) What is the independent (manipulated) variable?
4) What is the dependent (responding) variable?
5) What should Tina's conclusion be?
Answer:
Individuals from test 1Individuals from test 2CaffeineHeart rateTina´s hypothesis is correct. Caffeine increases the heart rate of an earthworm.Explanation:
During an experiment, data from an experimental group is compared with the data from a control group. Both groups are selected from the same pool or population, so they are identical in all aspects except for the independent variables.
The control group is used to identify any other factors influencing the results obtained in the study, apart from the modified variables of the treatment.
The experimental group is the one affected by the experimental procedure or treatment. The researcher voluntarily changes the independent variables in the experimental group to observe how they affect the group under study. These variables are kept constant in the control group, not influencing the results, while the experimental group receives the treatment. There can be several experimental groups.
Independent (manipulated) variable: Refers to all the variables in an experiment that provoke a response in another variable. An independent variable is the one that changes or is controlled and modified in the experiment to analyze how another variable responds to it. It changes to analyze its effects on the dependent variable. Usually, the independent variable is represented by the X letter. Dependent variable: Refers to the variable, which response depends on any change in the independent variable. It represents a quantity of something which value depends on how the independent variable is modified. The change in the dependent variable might be proportional or inversely proportional to the change in the manipulated variable. It is usually represented using the letter Y. Controlled variable: Refers to the variables that have no influence on the results. These variables do not affect the change in the dependent variable values.1) What is the control group?
Individuals from test 1 compose the control group. They are not affected by the treatment. Tina just uses them to measure the normal heart rate and to compare them with individuals from test 2.
2) What is the experimental group?
Individuals from Test 2 compose the experimental group. They are affected by the treatment. Tina drops caffeine on their skin to see how it affects the worms.
3) What is the independent (manipulated) variable?
Caffeine is the independent variable. Tina manipulates the number of drops she places on the worm´s skins.
4) What is the dependent (responding) variable?
Heart rate is the dependent variable. Tina evaluates how the heart rate changes in individuals with or without caffeine.
5) What should Tina's conclusion be?
Caffeine increases the heart rate of an earthworm. It changes from 50 to 68 bpm. Tina´s hypothesis is correct.
