Which scenarios is the best example of positive feedback?
Explanation:
As Body temperature decreases, your body begins to shiver and you begin to sweat.
please follow meYour airways are coated with a thin layer of liquid called ASL and a mucus gel layer, both which neutralize foreign particles to prevent infection. In people with
Cystic Fibrosis, a gene has an error, which causes the cells of the airways (lungs, etc) to have defective plasma membranes The ASL and mucus are much
thicker than usual near the defective cells, causing a lot of lung congestion because the defective cells allow too much salt into the cells Why would allowing too much salt into the cells create thicker ASL and mucus?
À. The increased salt in the cells makes the person thirsty, leading to thickened ASL and mucus in the lungs
B. The increased salt in the cells causes water from the airways to move into the cells by osmosis, thickening the ASL and mucus in the lungs.
C. The increased salt in the cells causes water from the cells to move into the airways, thickening the ASL and mucus in the lungs

Which part of an atom is responsible for absorbing energy and releasing it as colored light?
Answer:
The electron
Explanation:
The electron is responsible because it absorbs incoming energy by switching it's orbiting level one step higher and when releasing the given energy it jumps back to it's original orbiting level and emits visible light!
Answer: photons
Explanation: When an electron jumps from the second energy level to the first, it gives off energy by releasing light. The atom aborbes or emits the light in photons. Each photon has definite energy.

7) Yes, the body does get all the energy from the sun. When we eat animals that eat plants, the energy from CR goes to the consumers.
8) No, CR is the result of photosynthesis, if no CR were around, photosynthesis could not begin.
9) Plants needs energy to help move things in and out of the cell. Plants also need energy to grow and reproduce.
How are chemosynthetic bacteria different from photosynthetic bacteria?
A Chemosynthetic bacteria do not require water B Chemosynthetic bacteria eat tube wormS. C. Chemosynthetic bacteria require intense sunlight
D. Chemosynthetic bacteria do not need light.
Answer:
D
Explanation:
Chemosynthetic bacteria different from photosynthetic bacteria in that Chemosynthetic bacteria do not need light and the correct option is option D.
Chemosynthetic bacteria are a type of bacteria that can produce their own energy and organic compounds without the use of sunlight. They obtain their energy by oxidizing inorganic substances, such as hydrogen sulfide or methane, and using the energy released from these chemical reactions to synthesize organic molecules.
In contrast, photosynthetic bacteria, including cyanobacteria, use sunlight as a source of energy for photosynthesis. They have pigments, such as chlorophyll, that capture light energy and convert it into chemical energy through a series of biochemical reactions.
Chemosynthetic bacteria can thrive in environments with little or no light, such as deep-sea hydrothermal vents or certain underground ecosystems. They are able to utilize chemical energy sources to sustain their metabolic processes and support their growth and reproduction.
Thus, the ideal selection is option D.

what is the relationship between kinetic energy and speed
Answer:
The energy transferred is known as kinetic energy, and it depends on the mass and speed achieved.
This equation reveals that the kinetic energy of an object is directly proportional to the square of its speed.
KE = 0.5 • m • v2
where m = mass of object
v = speed of object
That means that for a twofold increase in speed, the kinetic energy will increase by a factor of four. For a threefold increase in speed, the kinetic energy will increase by a factor of nine.
The kinetic energy of an object is a function of its speed.
More specifically, the kinetic energy of an object is directly proportional to the square of the speed of the object.
Mathematically, the relationship between the 2 quantities can be represented such that:
Kinetic Energy = 1/2 x mass x velocity^2
Velocity refers to the speed in a particular direction.
Thus, for a 2 fold increase in speed, the kinetic energy of an object increases in 4 folds.

Which best describes the nucleus of an atom?
a. It is thee negatively charged part of the atom
b. It contains no mass.
c. it is made of neutrons and electrons.
d. It is the most massive part of the atom
Answer:
The answer is D.
I used the process of elimination to find your answer if you want to understand further look in my explanation. I hope I can help! Have a great day!
Explanation:
So the negatively charged part of a atom is the electron cloud so A is wrong because it would be in the wrong spot. Plus the nucleus is positively charged because it contaims only protons ans neutrons. Neutrons are neutral and protons are positive so the protons over power the nuetrons. Therefore the nucleus is not made of neutrons and electrons so C is wrong. And B is also wromg because the nucleus does indeed have mass. So the correct answer is D, it is the most massibe part of a atom.

Which planet is most similar in temperature to Earth?
Answer:
It depends; If you're asking for very temporary moments on the planet, it would be mercury, because its temperature ranges from 427 degrees to -180 degrees Celcius. If you were to stand just in the right spot at just the right time, its temperature would be the same as the earth's temperature.
But if you are asking about longer periods of time, it would be Mars. Its average temperature is around -60 degrees celcius, but its summer can get up to 20 degrees celcius.

4. How are atoms related to molecules?
Answer:
Every combination of atoms are molecules. A compound is a molecule made of atoms from different elements.
Explanation:
Atoms are related to the molecules as they are the building blocks of the molecules, and they make different molecules based upon the bonding pattern of the atoms present in the molecules or in the compound.
What is the significance of the atoms and molecules?They are both significant because they are both the basic building blocks of matter, and atoms in a molecule are held together by various types of bonds, such as ionic bonds and covalent bonds, etc. Water molecules, for example, are made up of oxygen and hydrogen, which are the atoms that combine to form the molecule.
Hence, atoms are related to the molecules as they are the building blocks of the molecules, and they make different molecules based upon the bonding pattern of the atoms present in the molecules or in the compound.

How is cell differentiation different than mitosis?
Cell differentiation does not cause proliferation.
Cell differentiation produces cells with different gene expressions.
Cell differentiation only occurs after a wound.
Cell differentiation produces cells with different DNA.
Answer:
it should be produces cells with different gene expressions
The process of cell differentiation is different than mitosis by the mechanism that cell differentiation produces cells with different gene expressions. Thus, the correct option for this question is B.
What is Mitosis?Mitosis may be defined as a type of cell division that produces two genetically identical daughter cells from a parental cell. It generally synthesizes diploid daughter cells. This process of mitosis occurs in the eukaryotic cells.
The generation of specialized cell types is called cell differentiation. It is the process during which a cell ceases to divide and develops specialized structural elements and distinct functional properties due to different gene expressions.
After the termination of cell differentiation, cells are structurally and functionally specialized with respect to their functions.
Therefore, the process of cell differentiation produces cells with different gene expressions. Thus, the correct option for this question is B.
