Which statement is correct about how lights travel

Answers

Answer 1

Answer:

1. Answer: Light can travel in a vacuum, and its speed is constant if the source is moving or stationary.  

Light travels at constant speed in vacuum even if the source is moving or stationary. If the source is moving, the apparent frequency/ wavelength changes.

If you were to expose cells that are undergoing aerobic respiration to a radioactive carbon isotope in the form of C6H12O6, which of the following molecules would you not expect to be radiolabeled?

(a) pyruvate
(b) NADH
(c) water
(d) CO2

Answers

Answer:

The correct answer is option (c) "water".

Explanation:

Cells that are undergoing aerobic respiration and are exposed to a radioactive carbon isotope in the form of C6H12O6 will have radiolabeled its molecules that are involved in aerobic respiration and contain carbon. In this case, the only molecule that does not contain carbon in the options is water, therefore water will not be radiolabeled. Water is comprised of two atoms of hydrogen and one atom of oxygen, while pyruvate, NADH and CO2 all contain carbon.

DQ19: A pea plant must have exactly one of each of the following pairs of traits: Short (s) or tall (t); round (r) or wrinkled (w) seeds; yellow (y) or green (g) peas; and white (wh) or purple (p) flowers. For example, a pea plant can be short with wrinkled seeds, green peas and white flowers. How many different classifications of pea plants are possible

Answers

Answer:

There are 16 possible different classifications of pea plants.

Explanation:

In order to get the number of classifications, you must multiply all the possibilities by each other in each trait. This is, each trait has two states (short or tall, round or wrinkled, yellow or green, white or purple) and are referred to as "pair of traits". These must be multiplied with the other pairs of traits. So, the number of different classifications of pea plants is:

the number of high states x number of shape states x number of peas color sates x number of flower color states = 2 x 2 x 2 x 2 = 16.

During artificial cross-pollination, the scientist completely controls the transfer of pollen from one flower to the stigma of another.

What do you mean by Cross-pollination?

Cross-pollination may be defined as a type of pollination in which sperm-laden pollen grains are transferred from the cones or flowers of one plant to egg-bearing cones or flowers of another.

Any artificial thing requires the interference of human activity. This activity by human increase the chance of those who give better productivity in every aspect.

Answers

Answer:

Day-to-day changes in weather can influence how we feel and the way we look at ... Meteorology is the science of forecasting weather.

Answer:

1. Many fronts cause weather events such as rain, thunderstorms, gusty winds, and tornadoes. At a cold front, there may be dramatic thunderstorms. At a warm front, there may be low stratus clouds. Usually, the skies clear once the front has passed.

2. As the warm moist air rises, towering clouds often form releasing energy in the form of brief, intense rain storms with high winds and lightning. On the other hand, warm fronts will ride up and over cold air near the surface. As it rises, the air cools and the humidity condenses to form clouds and precipitation.

Answer:

reclamation

Explanation:

The process of attempting to return an environment to its previous state once mining is complete is known as reclamation.

Reclamation efforts after mining are all geared towards returning the mining sites to its original states before mining.

Mining generally degrades the environment and disrupts the natural equilibrium of the various natural processes in the environment such as nutrient cycling. Some of the efforts at reclaiming a mining site include plant of trees, restoration of habitats, etc.

Explanation:

Anya and Greg are working in their research laboratory. Anya tells Greg that one of the mice has a 50% probability of having the alleles DD and a 50% probability of having the alleles Dd. How can Anya explain her reasoning? In two out of 50 times, the mouse has the alleles DD or Dd. The probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd. The mouse is twice as likely to have the alleles DD than it is to have the alleles Dd. There are two more possible outcomes besides the mouse having DD or Dd alleles.

Answers

Answer:

Option B: The probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd.

Explanation:

Anya tells Greg that one of the mice has a 50% probability of having the alleles DD and a 50% probability of having the alleles Dd.

She can explain her reasoning by saying that both pairs of alleles (DD and Dd) has equal chance of being expressed i e, the probability that the mouse has the alleles DD is equal to the probability that it has the alleles Dd. Both pairs each has 0.5 chance of occuring.

Answer:

Explanation:

A Dominant Allele is an Allele that express itself.

DD- this represent a dominant homozygous allele

Dd- represent a dominant heterozygous allele

When an individual with DD is crossed with Dd we will have DD,Dd,DD,Dd

Phenotypic ratio is 2:2

i.e homozgous dominant crosses with heterozygous dominant

which means both DD and Dd have 50% chance of occuring in the genotype and the probabality is the same.

Note that in the phenotype of an individual with homozygous dominant (DD) is the same phenotype with heterozygous dominant(Dd)

Anaerobic respiration happens in muscle cells and yeast cells.
The equation describes anaerobic respiration in muscle cells.
glucose ---> lactic acid
How can you tell from the equation that this process is anaerobic?
would the answer just be no co2 is produced?

Answers

Answer:

Am I think Co 2 will not be released but rather Glucose will be released

Explanation:

This is because

C6H12O6>2C5H5OH+2Co2 + Energy

there fore glucose is produced

From the equation "glucose → lactic acid," we can infer that the process is anaerobic. One way to determine this is by the absence of carbon dioxide (CO2) in the equation.

Glucose is entirely oxidized to create carbon dioxide, water, and energy during aerobic respiration, which takes place in the presence of oxygen.

Yet, in anaerobic respiration, the lack of oxygen causes an incomplete breakdown of glucose, producing additional byproducts such lactic acid as a result.

Muscle cells have the ability to transition to anaerobic respiration in order to satisfy their energy needs when there is insufficient oxygen.

Muscle cells have the ability to engage in anaerobic respiration, which produces ATP (adenosine triphosphate), the cellular energy currency, by partly metabolizing glucose, during hard exercise or when oxygen supply is constrained.

During anaerobic respiration, lactic acid builds up in muscle cells, which can lead to exhaustion and pain.
