Answer:
The color of the pigment comes from the wavelengths of light that are reflected, or in other words, those wavelengths not absorbed. Chlorophyll, the green pigment common to all photosynthetic cells, absorbs all wavelengths of visible light except green, which it reflects. This is why plants appear green to us.

Explanation:
The model shows a substance crossing a cell membrane.
Solute particle Cell membrane
Which of the following describes the process?
a.
The model shows the process of active transport because the solute particles are
moving from an area of low concentration to an area of high concentration.
b.
The model shows the process of bulk transport because the solute particles are
moving from an area of low concentration to an area of high concentration.
C.
The model shows the process of diffusion because solute particles are moving from
an area of high concentration to an area of low concentration.
d.
The model shows the process of osmosis because the solute particles are moving
from an area of high concentration to an area of low concentration.
Answer:
C
Explanation:
Solute particles are constantly moving around in a solution, interacting with one another, and dispersing in different directions. Simple diffusion is the term used to describe the random mixing of solute particles in a solution. Thus, option C is correct.
What are the factors in solution for solute movement?Active transport is the term used to describe the movement of solute particles from low to high concentration.
Because they will have more kinetic energy. The rate of diffusion increases as surface area increases.
Particles of the solute move against the concentration gradient during active transport. Solute particles travel from a low-concentration region to a high-concentration region in this manner.
Therefore, model shows the process of diffusion because solute particles are moving from an area of high concentration to an area of low concentration.

What part of a microwave oven protects humans against radiation?
1. glass doors
2. plastic outer covering
3. metal shields
4. magnetrons
Answer:
metal shields
Explanation:
I took the quiz and exam
Humans are shielded from radiation by metal parts of a microwave oven. So, the correct option is C.
What is Microwave oven?A microwave oven, often known as a microwave or electronic oven, is a device that uses microwaves, which are high-frequency electromagnetic waves, to cook food. A microwave oven is indeed a compact, box-shaped oven that increases food's temperature by exposing it to an electromagnetic field with a high frequency.
Water, lipids, carbohydrates, and a few other molecules absorb the microwaves, which causes their vibrations to produce heat. Hence, cooking time is significantly shortened because the heating takes place inside the food rather than warming the air around it. Metal components of a microwave oven protect people from radiation.
Therefore, the correct option is C.

How many water molecules are released in the synthesis of 10 maltose and 15 sucrose?
Answer:
10 water molecules are released in the synthesis of 10 maltose and 15 water molecules are released in the synthesis of 15 sucrose.
Explanation:
10 water molecules are released in the synthesis of 10 molecules of maltose and 15 water molecules are released in the synthesis of 15 molecules of sucrose because in a reaction, when two glucose molecules fuse together forming a molecule of maltose with the release of single water molecule while on the other hand, when glucose and fructose fuse together forming sucrose releases single molecule of water, so in each case, one molecule of water is produce.

Describe the niche of the giraffe.
Answer:
A niche is the part of an animal that plays important role in its environment.
A giraffes niche would be their long necks. With their necks they can stand up higher and eat where no other animals can reach to eat.
Giraffes don't have to contend with other animals for their food so they survive harmoniously with other animals.
Their necks are instrumental in much of this niche, determining what the giraffes eat and what they see.
The elongated necks of giraffes support them consume leaves, blossoms and fruit that are higher than most grazing animals can touch; only elephants can compete for food at the equivalent level
Explanation:
In ecosystems, plants transform light energy from the Sun into chemical energy when they make sugar. This sugar can then be consumed by other organisms to be used as building blocks for other molecules, such as proteins and fats, or it can be transformed into other forms of energy, such as kinetic energy, when the organism moves. Which of the following statements is supported by the above information? A. Energy can change forms, but only one kind of matter exists. B. Matter and energy must always remain in the same form and location. C. Matter and energy can change forms and locations in ecosystems.
Answer:
Matter and energy can change forms and locations in ecosystems.
Explanation:
Matter and energy can change forms and locations in ecosystems.
In the given information, light energy changed into chemical energy and then into kinetic energy, and sugar changed into proteins and fats as it moved from the Sun to the plant and then to other organisms.
It is important to note that although matter and energy can change forms and locations in an ecosystem, the total amount of matter and energy must always remain the same according to the laws of conservation of matter and energy.
