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
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.

PLEASE HELP!!!!! A black swan and white swan breed and produce offspring that are gray in color. What is the most likely explanation for this happening? A. The alleles for white and black have incomplete dominance, and they blend producing gray feather. B. It is a mutation, and there is no scientific way to explain the appearance of the gray feathers. C. It could be a situation of codominance producing the gray feathers from black and white alleles.
Answer: C
Explanation: All of them could be correct, but I think this is the correct answer. I’m only in middle school, so if your not rushing you may as well wait for someone else.
Answer:
La respuesta es
C. Podría ser una situación de codominancia produciendo las plumas grises a partir de alelos blancos y negros.
Explicación:
Ya que normalmente se expresará el alelo dominante, mientras que el efecto del otro alelo, llamado recesivo, queda enmascarado. Pero cuando hay codominancia, entonces ningún alelo es recesivo y el fenotipo de ambos alelos es expresado.

Explanation:
An experiment may be defined as a procedure which is carried out to refute, support, or validate a certain hypothesis or theories. Such experiments provides insight into the cause and the effect of a hypothesis by showing what outcome comes or results when some particular factor is being manipulated by the experimenter.
It is considered a scientific procedure which is undertaken to test a hypothesis or to make some discover or sometimes to demonstrate a known fact.
The results of these experiments may lead us to new question or new findings or theories. It result of the experiments may also be published in an scientific journal for the readers and scientist.
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
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.

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:
Both snake and frog are vertebrates and non vertebrates animals.
Explanation:
Snake is a reptile and almost used vertebrates and non-vertebrates in their nutrition. There are few species that are specialized in egg feeder, snake is one of that.
Most of the species has to fed 1 2 in a week. Snake used to eat most pups, mice, rabbits and ducks. Both frog and snake are carnivores. They eat prey, insects, mammals. Both snake and frog comes under the food chain. Frog eaten by snake or snake can eat frog.
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.

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

Matching fossils separated by vast oceans.
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

two systems interacting? What are the inputs and outputs of these systems?
EXPLAIN The scuba diver is a living system. The scuba gear, or self-contained
underwater breathing apparatus, is a system of air exchange. How are these
the body's response
. ,
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.
