Which of the following changes demonstrates a chemical property? *
O A substance breaks in half
A substance combusts (burns)
O A hammer bounces off a substance
O A substance floats in water

Answers

Answer 1

Answer:

The correct answer is B. Combustion is a chemical change. When a substance is burned, it forms new substances. Therefore, combustibility is a chemical property because it can only be observed when a substance undergoes a chemical change.

Explanation:

Hope that helps!

Answer 2

Answer:

The answer would be "A substance combusts (burns)".

Explanation

All of the other options are basic physical changes that don't alter the substance on a molecular level, whereas burning a substance permanently changes the molecular makeup.

Suppose a scientist developed a hypothesis stating that a certain substance slowed down the growth of chili pepper plants. Briefly describe a controlled experiment
the scientist could conduct to test the hypothesis. Identify the controlled variables, the independent variable(s), and the dependent variable(s).

Answers

Answer:

The experiment consists of three different treatments:

1- Fifty (50) chili pepper plants treated with the substance X suspected to slow down the growth  

2- Fifty (50) no treated chili pepper plants that grown in normal conditions

3- Fifty (50) chili pepper plants treated with a substance known to slow down the growth (positive control)

Dependent variable: plant growth

Independent variable: the amount of substance x (suspected to slow down plant growth)  

Explanation:

The dependent variable is the variable that is being measured, while the independent variable isn't changed by the other variables in the experiment. In this case, the question is how chili pepper plants grow in response to the substance x, which is suspected to slow down the plant growth. During the experimentation, the plant growth will represent the dependent variable being analyzed. On the other hand, chili pepper growth will be in response to changes in the amount of substance x the plants receive, therefore being the independent variable.

Hypothesis development  for substance.

A hypothesis is a temporary or tentative arrangement or explanation that is made for the experiment on the basis of an assumption. The experiments highlight the development of certain substances that slowed down to the growth of the chili pepper plans.

Thus the answer is slow growth, normal growth, and positive fast growth.

The assumed experiment consists of 3 treatments. As the first (50) chili pepper plants treated with substance X tend to slow down the growth. The second plant shows a grown in normal conditions. The 3rd plant sows the slow down the growth (positive control).Thus the dependent variable is then planted growth and the independent variable is substance X.

The cycle that powers the ocean currents, weather, and tectonic plates it called

Answers

Please pick me as the brainiest. It would make my day

I am 100% sure that the correct Answer is:

Convection current

Please do have a great rest of your day!

The cycle that powers the ocean currents, weather, and tectonic plates it called convection current​. The correct option is d.

What is convection current?

Convection is the spontaneous flow of a single or multiphase fluid caused by the combined effects of material property heterogeneity and body forces on a fluid, most commonly density and gravity.

Convection currents are generated by radioactive decay in the core as heat rises and falls within the mantle. The plates are moved by convection currents.

Plates move apart where convection currents diverge near the Earth's crust. Plates move towards each other where convection currents converge.

Convection currents propel Earth's rigid tectonic plates through the planet's fluid molten mantle.

Tectonic plates move away from each other in places where convection currents rise up towards the crust's surface, a process known as seafloor spreading.

Thus, the correct option is d.

Answers

Answer: nucleic acids

Explanation:

someone answer these 2 for me

Answers

Answer:

F=dominant, 6 fingers

f= reccessive, 5 fingers

Ff= 6 fingers( contains dominant gene)

if you combine Ff and Ff you get:

25% FF (6 fingers)

50% Ff (6 fingers)

25% ff ((5 fingers)

so only 25% will have 5 fingers (normal)

Answer2:

Dominant=normal hearing

Recessive= deafness

If one parent is RR and the other Rr, the offspring will be:

50% RR

50% Rr

so all the offspring will have normal hearing, and there is 0% of deafness.

I think it is tissue

The skin cells of a scorpion organize together to form a hard covering called a carapace, which helps protect the scorpion. "Tissue" is the term for a group of similar cells working together. The last option is the correct answer.

What is a tissue?

In a single-celled organism, cells perform all of the body's functions, whereas in multicellular animals, cells join together to form tissue, tissue joins together to form organs, and organs join together to form organ systems, and all functions are divided. By the time zygote formation occurs, there is only one cell present, and that cell has been divided, specialized, and assigned specific functions.

Some cells make stem cells, some make epithelial cells, and so on. The tissue is a group of cells having a similar function, such as epithelial tissue, which has many cells but all of them perform the same function, that of a skin cell; all of them have sweat glands, etc.

Hence, "tissue" is the term for a group of similar cells working together. The last option is the correct answer.

Which principle states that two species in the same habitat cannot have the same niche?
niche exclusion principle
competitive exclusion principle
habitat exclusion principle
population exclusion principle

Answers

Answer:

competitive

Explanation:

example 1: two male bucks cannot inhabit the same habitat or area because one needs all the females or pride for itself so it chases away the others

The competitive exclusion principle explains that two species occupying the same niche cannot coexist in the long term since competition is created between them for resources.

What is the competitive exclusion principle?

It is a phenomenon that refers to the competition that one species has with another and the dependence of one organism to develop in terms of the other organism.

In competitive exclusion, one species is displaced by another when their niches overlap and compete for the same resources.

Therefore, we can conclude that the competitive exclusion principle establishes that two species that have the same ecological needs cannot live together since they create competition between them for resources.
