Answers

Answer 1

Answer:

Ammonium chloride (sodium hydroxide is stronger but it isn't an option in the question)

pH 7 is neautral

pH higher than 7 is alkali

An alkali is a soluble base.

Ammonium chloride has the highest pH number so it must be a base.

What is the outcome of all chemical changes when two substances are combined?

A- A new substance forms with identical properties

B- The two substances release an odor

C- The two substances change color

D- A new substance forms with different properties​

Answers

Ans: D

Chemical changes:-
occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions.

Hope this can help.

Answer:

D- A new substance forms with different properties​

Explanation:

When a chemical change occurs, it causes the matter to form into a completely new substance. Because of this, the new substance will have different properties than the original substance. Options B and C are true for some chemical changes, but not all changes. Option A is incorrect because the substance has different properties than the original substance. Thus, Option D is correct.

How could the tomato plants response to being eaten by a hornworm caterpillar be described as a function of homeostasis

Answers

Answer:

First, it's important to get clear on the meaning of Homeostasis.

In simple terms, it refers to the capacity of a living thing (plant or animal) to react or behave in such a way that enables it to continue to survive irrespective of changes in its immediate environment.

       

Explanation:

In humans, the body has a system which reacts to the external stimuli of temprature. When the weather is hot, the brain through a sequence of electrical and chemical signals tells the skin to open up the pore, then we experience venting of sweating which cools the body and regulates internal heat. This is an instance of homeostasis.

This does not mean that the plant or animal is completely immune to such external changes.

In the case of the tomato plant, the hair on the leaves and stem of the plant is an example of Homeostatic responses which have evolved over the years to discourage predators such as the hornworm caterpillar from defoliating the plant.

Cheers!

Answer:

Please find the detailed explanation to this question below.

Explanation:

Firstly, homeostasis is the ability of an organism to use internally-controlled mechanisms to maintain a stable internal environment despite changes in its external environment. Homeostasis is an important phenomenon necessary for the survival of living organisms.

Hornworms caterpillar are notorious pests of tomato plants. However, tomato plants have been found not to stand still and get devoured. The plant responds to being eaten by these caterpillars by releasing chemicals that distracts their attention from the host plant and instead the caterpillars feed on one another.

Getting fed on by plants can disrupt the internal structure of plants, hence, the release of this defense chemicals by tomato plants is physiologically controlled in response to environmental stress i.e. pests, and it is done in order to maintain a stable internal condition. Therefore, the response of tomato plants to caterpillar pests is a FUNCTION of HOMEOSTASIS.

This frog is about to be food for a snake. Which type of nutrition does the snake use, and which type of nutrition does the frog use? Justify your answer.

Answer:

All animals are other-feeders. Their cells cannot make food for themselves like plant cells can. They gain energy and nutrients by eating other living things. The snake will get energy and nutrients by eating the frog. Frogs get energy and nutrients by eating other living things, such as insects and worms.

Answers

Answer:

The correct answer would be D, Ocean trenches/spreading centers mapped.

Explanation:

I hope this helps you. :)

The statement that doesn't describe evidences as regards Continental Drift Hypothesis is  : B: . Identical rock types found of continents separated by vast oceans.

Continental drift can be regarded as theory which gives explanation about the shifting and changing of position of  continents on Earth's surface.

This theory was set set up by Alfred Wegener, in the year 1912, continental drift help us to understand the similarities between look-alike animal as well as plant fossils, and how they were found on different continents.

Another evidence of this is how continents fit together like massive jigsaw puzzle pieces

Dog breeders maintain the purity of breeds by keeping dogs of different breeds apart when they are fertile. This kind of isolation is most similar to which of the following reproductive isolating mechanisms? a. temporal isolation b. behavioral isolation c. habitat isolation d. gamete isolation

Answers

i believe the answer is habitat isolation! hope this helped :)

The isolation practiced by dog breeders to maintain the purity of breeds is most similar to behavioral isolation

 (option b). is correct.

How do we explain?

Behavioral isolation is a reproductive isolating mechanism in which individuals of different species or populations have different behaviors or mating rituals that prevent them from successfully mating with each other. In the case of dog breeders, they keep dogs of different breeds apart during their fertile periods to prevent them from mating and producing mixed-breed offspring.

This behavioral isolation helps to maintain the purity of the specific breeds.

Therefore,  (option b). is correct.

underwater breathing apparatus, is a system of air exchange. How are these
the body's response
. ,

Answers

Answer:

Breathing in human on land or during swimming or scuba diving, the human inhales oxygen and exhales carbon dioxide, These carbon dioxide molecules creates "air bubbles" that are then ousted into the water body. The diver at that point draws air from the pressurized air tank, and can inhale or breath. This permits the diver to remain submerged for any longer than only one inhale, and can travel deeper underwater.

Inside this framework, the Oxygen is primary input to the oxygen tanks, which are then utilized by the scuba diver. The diver would draw the oxygen from the tank considered as output in this system.
