Which clue can be used to identify a chemical reaction as a combustion reaction? Oxygen is a product. A hydrocarbon reacts with oxygen. Water and carbon dioxide react. The reaction involves ions.

Answers

Answer:

A hydrocarbon reacts with oxygen

Explanation:

The clue that can be used to identify a chemical reaction as a combustion reaction from the options would be if a hydrocarbon reacts with oxygen.

Basically, a combustion reaction is a kind of reaction involving oxygen and another reactant with energy being released in the process. The energy is usually in the form of light and heat.

Thus, following the definition:

Oxygen is rather a reactant, and may not be a product in combustion reactionsWater reacting with carbon dioxide is not a combustion reactionReaction involving ions may not be a combustion reaction

The only reaction that may identify as a combustion reaction is, therefore, the one involving hydrocarbon and oxygen.

Answers

Answer:

The answer to the question is true

Yes, Your white blood cells account for only about 1% of your blood, but their impact is big. White blood cells are also called leukocytes. They protect you against illness and disease. Think of white blood cells as your immunity cells. In a sense, they are always at war. They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health. When your body is in distress and a particular area is under attack, white blood cells rush in to help destroy the harmful substance and prevent illness.

can two organisms occupy the same niche in a community? why or why not?

Answers

Answer:

no

Explanation:

two organisms cannot occupy the same niche or else they would compete for the role :)

It depends if they are part of the same species. But that was not included in the question so no, two organisms cannot occupy the same niche in a community.

A student conducted an experiment with two rose plants to determine if a liquid formula for fertilizer produced greater growth than a dry formula. After testing each fertilizer on two different plants for one month, his data led to the conclusion that the liquid formula was a better promoter of plant growth. When he described his conclusion to his teacher, she told him he needed to conduct additional trials. The teacher most likely asked for additional trials because she did not believe the new formula helped plants grow better than the old formula. it was necessary to see data from more plants before the conclusion could be accepted. it was necessary to have tested the fertilizer on different kinds of plants. she thought he should test additional fertilizer formulas on the same two plants.

B. acknowledge their opinion and make sure you have a valid argument to respond with. If you do not have a valid argument, you may be in the wrong. C. ignore them, their opinion doesn’t matter when you have already formed your own opinion. D. accept their opinion as correct, especially if they have a degree.

Answers

Answer is b you should go over their opinion and make sure you have enough valid reasons to challenge wether you are right

Opinions are the views formed concerning something. When an opinion is challenged, then one should acknowledge them and ensure that a valid argument is presented in the counterclaim. Thus, option B is correct.

What is a counterclaim?

A counterclaim is a rebuttal made against the claim made previously and is the response of an individual to the presented opinions or judgments. It is generally presented to clear and oppose the ideas claimed by the opposition.

If an idea of a person is challenged then the person can respond by presenting a reasonable argument that can validate the ideas and opinions as true and accurate rather than getting them as incorrect.

If a valid argument is not presented then there might be a possibility that the ideas and opinions presented were not true or correct.

Therefore, one should acknowledge other people's opinions by providing a valid argument.

In the thylakoid membranes, what is the main role of the antenna pigment molecules?
a) split water and release oxygen to the reaction-center chlorophyll
b) harvest photons and transfer light energy to the reaction-center chlorophyll
c) synthesize ATP from ADP and Pi
d) concentrate photons within the stroma

Answers

Answer: Option B.

harvest photons and transfer light energy to the reaction-center chlorophyll

Explanation:

In the thylakoid membranes,the main role of the antenna pigment molecules is harvest photons and transfer light energy to the reaction-center chlorophyll because the photon of light move until it get to a molecule in the chlorophyll. When it reaches the molecule, it causes an excitation of electrons in the chlorophyll. The energy then present allow it to break free from the chlorophyll atom, which indicate chlorophyll donating an electron and the energy that is absorbed is then converted to heat.

Water has the property of having a high specific heat. This trait has a great influence on maintaining homeostasis within the body. Which of the following accurately explains what it means to have a high specific heat

Answers

Answer:

We can write the specific heat as:

C = (dU/dT)

Where C is the specific heat, U is the internal energy and T is the temperature.

This is:

"How much does change the internal energy when the temperature changes".

Having a high specific heat (and positive) means that for every little increase in the temperature we will have a large change in the internal energy.

What does this mean?

Think in the inverse way:

A larger specific heat means that we need a large amount of heat (the heat is energy) to change a little the temperature.

Then this is good, because even when receiving a lot of heat, the body temperature will remain about the same.

What are possible products of glycolytic, or anaerobic, catabolism?

Answers

Answer:

The products of a glycolytic metabolism is lactic acid and the increase of the insulin enzyme at the plasma level.

Explanation:

Lactic acid is the product of the reaction of glucose catalysis in oxygen-deficient states such as in anaerobic activity.

Lactic acid is an acid that can be metabolized by the body, which accumulates in the muscles, and is generated once the physical activity has finished or in the last stages.

Insulin, once generating the rest of the activity, or the cessation of the action, comes into play at the plasma level and increases, in order to neoform new energy reserves (glucose) and thus prepare for the next action.

This hormone has the opposite effect to glucagon.

please mark as the brainliest (ㆁωㆁ)

Answer:

B, in the cytoplasm

Explanation:

Most prokaryotes carry a small amount of genetic material in the form of a single molecule, or chromosome, of circular DNA. The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane. This question is worded quite strangely, as the nucleus is an organelle it would make better sense to say in the organelles but it refers to organelles as plural and it's not in any other organelle but the nucleus, the cytoplasm is what surrounds the organelles and has direct contact with the cell membrane, the nucleoid also does not contain any enclosing membrane

which of the following is not a reactant needed for photosynthesis
A. sunlight
B. oxygen
C. carbon dioxide
D. water

Answers

Answer:

I think it B

Explanation:

By definition of photosynthesis, oxygen is not a reactant needed for photosynthesis.

First, you have to know that photosynthesis is a metabolic process carried out by certain cells of autotrophic organisms, that is, those that have the capacity to make their own food, such as plants.

With this process, plants capture the energy of sunlight and transform it into chemical energy, to produce organic matter.

Photosynthesis takes place in 2 stages:

In the first stage the plants absorb water from the soil through the roots. Through their stems they transport it to their leaves. In these it meets the sunlight captured by chlorophyll, which breaks the water molecule, separating hydrogen (H) from oxygen (O2).The other stage is capturing carbon dioxide. This provides the carbon and oxygen atoms that, together with hydrogen and stored energy, will form the glucose molecule, from which compounds are produced that are the basis of food for plants and other living beings.

Then, sunlight, carbon dioxide and water are needed for the photosyntesis, while oxygen is released to the environment.

This is sunlight, carbon dioxide and water are reactants needed for photosyntesis, and oxygen is not a reactant needed.
