Which piece of observation would support your explanation that the chameleon use a physical characteristic adaptation to survive in its environment?

A) A change in skin color
B) An increase in number of eggs
C) Carrying eggs in their mouth
D) Living in large groups

Answers

Answer:

A Change its skin

Explanation:

the Chameleon changes it skin to intimidate predators or to blend into an enviroment. And since changing the color of your skin is physical its A!

Adaptations are the characteristical behavior and physical changes. A change in skin color is the physical adaptation of a chameleon to survive in the environment. Thus, option A is correct.

What is adaptation?

Adaptations are the modifications and transformations a species adapts over time in their physical appearances in response to the stimuli that allow them to survive in the surroundings.

Physical adaptation includes the structural change in the shape, the color of the body, fur, and thickness and thinness of the body fur. A change in the skin color of a chameleon allows it to blend into its environment hence, protecting it from predators.

Therefore, the change in the skin color of a chameleon is a physical adaptation.

Which best explains why the rate of a reaction decreases at significantly higher temperatures?

A. The activation energy increases.

B. The shape of the enzyme changes.

C. The enzyme-substrate complex forms.

D. The bonds between substrates are broken.

Answers

Answer:

B

Explanation:

At significantly higher temperatures, the rate of an enzyme-catalyzed reaction decreases because the shape of the enzyme changes at high temperatures. Enzymes are proteinous in nature, and as such, are generally sensitive to high temperatures.

They simply become denatured by high temperatures. In other words, they lose their original shape and their catalyzing abilities as the temperature gets progressively high during the course of reactions, thus, decreasing the rate of a reaction.

The correct option is, therefore, B.

Zaccharias Janssen was a scientist who studied properties of light and invented one of the first compound microscopes in the late 1500s. Which property did Janssen most likely believe about light during the time of his invention?

Answers

Answer:

Light bounces off surfaces property most likely believed by Janssen about light during the time of his invention

Explanation:

Zacharias Janssen is ascribed as a man to discover the compound microscope. Its purpose is to amplify diminutive things so characters can analyze them. There is a mirror attached under the microscope and when light bounces off the mirror it reaches through and nearby the specimen being viewed.

Some elements do not receive light. When a light wave is reflected off a facade, it proceeds back off at an angle similar that the wave beats the surface. Using these more innovative concepts about light enacted scientists to compose new inventions.

Answers

Answer:

osmosis

Explanation:

plants use osmosis whic is moving water though a semipermial membrane to draw up water.  It moves from places of high conetartions of water (dirt)  has to  is less water (roots). When it does this the plant mains homeostasis by getting water up useing their xylem (tubes in stems) to the leaves.

Plants use osmosis which is moving water though a semipermial membrane to draw up water.

What do you mean by osmosis?

Osmosis is the spontaneous net movement or diffusion of solvent molecules through a selectively-permeable membrane from a region of high water potential to a region of low water potential.

Osmosis is the movement of water across a semi-permeable membrane from an area of low solute concentration to an area of high solute concentration. Osmosis helps regulate the flow of water in and out of cells, which is crucial to their function.

The rate of osmosis always depends on the concentration of solute. The process is illustrated by comparing an environmental or external solution to the internal concentration found in the body.

Which of the following is NOT in part of the natural selection process?

A. a species produces more offspring than can survive
B. an organism adapts to their environment causing variation
C. individuals competing with each other
D. fossils being formed

Answers

Answer:

the selection that is not a natural selection process is D: fossils being formed

Answer:

D. Fossils being formed

Explanation:

In the natural selection process, the point is that the animal which is best adapted to the environment survives, so their offspring can survive and produce more offspring that adapts. This is because organisms need to adapt to their environment to survive. Without natural selection, most animals would be too weak to live in their own habitat.

So when we see the answer choices, we have to ask if the species could continue to live and adapt.

A- the species produces more offspring that can survive. Yes, the species can continue to live and adapt.

B- an organism adapts to their environment. Yes, the species can continue to live and adapt.

C- individuals competing with each other. Yes, the better species will win, and continue to live and adapt

D- fossils being formed. No, this has nothing to do with the process of living and adapting. It is in fact the opposite, since it relates to the species dying.

So the answer is D

B) a lens that causes parallel light rays to separate from each other
C) a lens that allows parallel light rays to pass without changing directions
And D) a lens that causes parallel light rays to focus at a specific location

Answers

Answer:

D) a lens that causes parallel light rays to focus at a specific location

Explanation:

Lexically, to CONVERGE means to MEET. Converging lens, also known as double convex lens is that which causes rays of parallel light to become focused at a point i.e meet at a specific location.

The parallel rays of light come from different direction but the converging lens is structurally suited to cause them to converge or focus at a point.

Also, there should be constant movement leads to the electrical current.

If a couple has four daughters the % chance of their next child being a daughter is

Answers

Answer:

50% chance

Explanation:

Humans have two sex chromosomes, the X chromosome and the Y chromosome. Males inherit both X and a Y chromosome, while females inherit two X chromosomes. Thus, the sex of the child is determined by the sex chromosome carried by the male gamete (i.e., X or Y chromosome) which fuses with the egg cell (always containing an X chromosome). In consequence, the chance of having a sperm containing an X chromosome (i.e., the chance of having a girl) is an independent event of previous fertilization events (which led to the formation of 4 different female zygotes), thereby the probability will be 50%.

Which has a lower albedo, a black sheet of paper or a white sheet of paper?

Answers

Well let's see, the substance with the highest albedo value will absorb less light and will reflect most of the light falling on it. The substance having the lowest albedo will absorb most of the lights falling on it. A black sheet of paper will absorb most of the light falling on it, so this means that a black sheet of paper will have the lower albedo

Subcontracting would involve a cost per boat of $3,100, and expansion would require an annual fixed cost of $60,000 and a variable cost of $1,700 per boat.
