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.

Light bounces off surfaces

Why do geologists think Earth's core contains mostly iron?
A. The crust contains a mixture of iron and silicon.
B. The crust contains no nickel.
C. Other orbiting bodies contain more iron than Earth's crust does.
O D. The moon's crust contains far less iron than Earth's crust.
Answers
Answer:
It should be D
Explanation:
I hope this helps! Let me know if I am wrong.
The geologists think Earth's core contains mostly iron is to be considered as the option c. Other orbiting bodies.
Reason for thinking of geologists:Here the thinking should be earth core that comprises iron since the earth should contain the powerful magnetic field that is due to the molten iron in the core.
Also, there should be constant movement leads to the electrical current.
hence, the option c is correct.

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

2. Just as in humans, systems interact in plants to maintain homeostasis and accomplish the functions of transport, reproduction, and response. What are some examples of plant processes that involve an interaction between stems, roots, and leaves?
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 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.
