Which product forms from the reaction between nitrogen (N)
(CI)?
A. NCI
B. NCI
C. N2CI
O D. N2C1

Answers

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 NCl3

Answer:

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.

Global warming from human activity. Mainly the burning of fossil fuels. There are many solutions that are already available. Such as solar, wind, and geothermal energy. The issue is that these solutions also have problems and are expensive. Likely a combination of them and the engineering of ways to safeguard pollutants so they don’t make it into the ecosystem will be the best way that this will improve.

Which substance in chloroplasts is a green pigment that absorbs energy for
photosystems?
O A. NADPH
O B. ATP
O C. Chlorophyll
O D. Thylakoids

Answers

Answer:

C. Chlorophyll

Explanation:

Chlorophyll is the green pigment that absorbs the light energy for photosystems.

The substance in chloroplasts that is a green pigment and absorbs energy for photosystems is chlorophyll, which is present in Option C, as chlorophyll is the primary pigment responsible for the green color of most plants as it reflects green light,

What is chlorophyll?

Chlorophyll is a type of pigment that is responsible for the green color of leaves, stems, and other plant parts, and it is found in the chloroplasts of plant cells, specifically in the thylakoid membranes, where it plays a central role in photosynthesis, and chlorophyll absorbs light energy from the sun. During photosynthesis, chlorophyll absorbs light energy and transfers it to other molecules in the photosystems, where it is used to generate ATP and NADPH, and these energy-rich molecules are then used in the light-independent reactions of photosynthesis to produce glucose and other organic compounds.

Hence, the substance in chloroplasts that is a green pigment and absorbs energy for photosystems is chlorophyll, which is present in Option C.

The density of a white dwarf is

Answers

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.

that would decrease the rate of the reaction?
A. Have the people on the dance floor choose a partner.
B. Have more people get on the dance floor.
C. Have some people get off the dance floor.
D. Have the people on the dance floor move faster.

Answers

Answer:

it's either C or D

The students simulate a situation that might cause the reaction rate to decrease, such as having some people leave the dance floor while others move more quickly. So, the correct options are C and D.

What is Reaction rate?

The pace at which a chemical reaction occurs is known as the rate of the reaction. It is proportional to the rise in product concentration per unit time and the fall in reactant concentration per unit time. Response times can differ wildly.

For instance, because it happens quickly, wood burning has a fast reaction rate, whereas iron rusting has a low rate of the reaction because it happens gradually.

For the aforementioned illustration, the students act out a scenario that can result in a slower reaction time, such as having some participants leave the dance floor whereas others move more swiftly.

Therefore, the correct options are C and D.

These new arrivals: Group of answer choices tend to speed up adaptation to new food plants speed up the process of speciation accelerate differentiation between the two populations tend to slow divergence of the two populations

Answers

Answer:

Hello. None of the answer options is correct, as the new arrivals delay adaptation to new food plants.

Explanation:

The arrival of new birds increases competition for food. This makes the birds that have just arrived have some difficulty in accessing food, as they will have to compete with the birds that are already on the island. This makes the novice birds look for food plants they already know, which delays their adaptation to feeding new plants they do not know.

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?

Answers

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.
