The Doppler effect suggests that sound waves are relative to the observer. You know if an object is coming or going from the sound it makes. Light waves follow the Doppler effect also. However, instead of sound changing, you know if an object is coming or going _____.

Answers

Answer 1
Answer: from the brightness of the light of course. If the brightness is increasing it means the the light source is approaching and if the brightness is decreasing it means the light source is leaving.
Answer 2
Answer:

Answer:

The light waves also follow the Doppler effect. However, instead of changing the sound, you know whether an object is coming or going through the brightness of the light.

Explanation:

The doppler effect is a physical phenomenon. This phenomenon allows us to perceive if an object is approaching or moving away through the wave effect that that object produces in relation to an observer. This is because when a wave is propagated the speed of that wave depends on the environment in which it is being emitted. For this reason, the speed of this wave will be constant even if the observer moves, but the frequency and movement of this wave varies in relation to the observer's position. In this case, the Doppler effect suggests that the sound waves are relative to the observer. You know if an object is coming in or out of the sound it produces. The light waves also follow the Doppler effect. However, instead of changing the sound, you know whether an object is coming or going through the brightness of the light.

Mitosis and meiosis are methods of cell division. Which of the following is true of these two methods? A. Meiosis involves only one division, while mitosis involves two divisions. B. Mitosis involves two or more divisions, while meiosis involves exactly two divisions. C. Meiosis involves two or more divisions, while mitosis involves exactly two divisions. D. Mitosis involves only one division, while meiosis involves two divisions.

Answers

Answer:

D. Mitosis involves only one division, while meiosis involves two divisions.

Explanation:

Mitosis and meiosis are processes of cell reproduction that happen in living beings. They originate cells for different purposes. Each mitosis produces two cells equal to the source. An meiosis creates four daughter cells with half the genetic material of the mother cell.
D. Mitosis involves only one division, while meiosis involves two divisions.


Mitosis --> Two identical diploid daughter cells from one division

Meiosis --> Four unique haploid daughter cells from two divisions

A researcher proposes a model to explain how enzyme-substrate interactions determine enzyme specificity. The model is based on the idea that substrate molecules form favorable interactions with the amino acid side chains in an enzyme’s active site. Based on the model, which of the following statements best explains an enzyme’s specificity for a particular substrate molecule?a. A hydrophilic molecule interacts with nonpolar side chains in the enzyme’s active site.b. A hydrophobic molecule interacts with polar side chains in the enzyme’s active site.c. A molecule with positive charges interacts with positively charged side chains in the enzyme’s active site.d. A molecule with negative charges interacts with positively charged side chains in the enzyme’s active site.

Answers

Answer:

Option- D

  • A molecule with negative charges interacts with positively charged side chains in the enzyme’s active site.

Explanation:

  • A researcher proposes a model to explain how enzyme-substrate interactions determine enzyme specificity. The model is based on the idea that substrate molecules form favorable interactions with the amino acid side chains in an enzyme’s active site.Based on the model, the following statements best explains an enzyme’s specificity for a particular substrate molecule, which is "A molecule with negative charges interacts with positively charged side chains in the enzyme’s active site."

Answer:

D. A molecule with negative charges interacts with positively charged side chains in the enzyme’s active site.

Explanation:

Because opposite charges attract, a molecule with negative charges will form favorable interactions with positively charged side chains in an enzyme’s active site. Based on the model, the favorable interactions helps explain the enzyme’s specificity for the molecule as a substrate.

Which of the following is a radical? O H OH H2O

Answers

Answer;

OH-

Explanation;

  • Radicals are molecules that contains at least one unpaired electron. They are formed when a single covalent bond breaks to leave an unpaired electron on each of the two species created by the breaking of the bond.
  • The answer for the question is OH, OH is an example of a radical, other common examples NH4+, NO3-, etc.
  • O, and H, are atoms. An atom is the smallest particle of an element that can take part in a chemical reaction.
  • H2O, is a molecules, A molecules is a substances made of two or more atoms. It is the smallest particle of a chemical element or a compound that has chemical propertie of an element or a compound.
If a radical is defined as a molecule with unpaired electrons,then the answer is OH.However,if you take the more general definition(an atom or molecule with unpaired electrons),then OH,O and H are all radicals.

P450 encodes an enzyme that detoxifies insecticides. Abc8 encodes a transporter protein thatpumps insecticides out of cells. Cps encodes an external structural protein located in theexoskeleton that greatly reduces the absorption of insecticides.

During embryonic development of animals, tissue layers form. This process of embryonic tissue development is called _____. embryology morphology gastrulation germination

Answers

Gastrulation is the process in which tissue layers are developed. These layers of tissue later become organs and organ systems. Germination is a process restricted to plants while embryology and morphology are considered studies of the growth and changes in organisms.

During embryonic development of animals, tissue layers form. This process of embryonic tissue development is called Gastrulation.
