I  think the correct answer from the choices listed above is the second option. <span>In order for us to see an </span>object<span> that is </span>non-luminous<span>, it must reflect some of the light it receives from a </span>luminous<span> source, such as the Sun. Hope this answers the question. Have a nice day.</span>

The correct answer is option B

The objects that allows the light to radiated from its body is called as luminous object. Whenever any light ray falls on any object it gets reflected back to the to the eyes of the observer. The light falls off the object that is not luminous and gets reflected back into the eyes of the observer. This makes the object visible to the people.

When trying to determine the rate of cellular respiration (an aerobic process), why is oxygen measured and not carbon dioxide
dusya [7]

Since both aerobic and anaerobic processes can result in the production of CO2, we couldn't be certain that cellular respiration was occurring.

Carbon dioxide:

Carbon dioxide is released during cellular respiration as a waste product. Cells that are capable of photosynthesis can utilize this carbon dioxide to create new carbohydrates. Additionally, oxygen gas is necessary to act as an electron acceptor during the process of cellular respiration.

There are two types of cellular respiration: aerobic (occurring when oxygen is present) and anaerobic (in absence of oxygen).

Now, carbon dioxide is emitted as a byproduct in both types of respiration.

Therefore, determining the rate of aerobic cellular respiration by measuring the amount of carbon dioxide emitted is impossible.

Therefore, to obtain the precise rate, we monitor oxygen rather than carbon dioxide.

Therefore, the correct response is that CO2 is created during both aerobic and anaerobic processes; we were unable to confirm if cellular respiration was occurring.

A geneticist is studying two traits in the fruit fly - eye color and wing shape. They perform a dihybrid cross. If the genes for
Len [333]

Answer:

3/16

Explanation:

<u>According to Mendel's law of independent assortment of genes, when a dihybrid cross involves two genes that assort independently and one of the parents is dominant for the two genes and the other is recessive, the phenotypic ratio of the offspring at F2 would be 9:3:3:1</u>. The proportion of the offspring with the dominant parental traits would be 9/16, those with the recessive parental traits would be 1/16, while those with mixed traits would be 3/16 each.

Assuming the eye color is represented by E and the wing shape is represented by W. At F2

     EeWw    x    EeWw

E_W_ - 9/16 (dominant for both eye color and wing shape)

E_ww - 3/16 (dominant for eye color and recessive for wing shape)

eeW_ - 3/16 (recessive for eye color and dominant for wing shape)

eeww - 1/16 (recessive for both eye color and wing shape)

<em>Hence, the proportion of the offspring with dominant phenotype for eye color and recessive phenotype for wing shape would be </em><em>3/16.</em>

Causes of megaloblastic anemia
lana66690 [7]

Answer:

Megaloblastic anemia is most often due to hypovitaminosis, specifically vitamin B12 (cobalamin) and folate deficiencies, which are necessary for the synthesis of DNA. [3] Copper deficiency and adverse drug reactions (due to drug interference with DNA synthesis) are other well-known causes of megaloblastic anemia.

What traits and trends characterize the primate lineage? Explain.
jenyasd209 [6]

Answer:

  • Hands and feet with 5 fingers
  • Generalized skeleton
  • Large brain

Explanation:

The order primate holds 300 or more species including monkeys, humans, gorillas, chimpanzees among others. The species included in this order share anatomic and functional characteristics such as:

  • Hands and feet with 5 fingers and opposable thumbs, for grabbing, holding a grip for a better arboreal lifestyle. Even though in some species such as humans these opposable thumbs in feet don't longer exist.
  • Plantigrade feet, which means that the toes and metatarsals are flat on the ground while walking.
  • Collarbone or clavicle present.
  • Nails instead of claws in the large majority of species.
  • Color vision.
  • Two brain hemispheres well developed, for special traits like social behaviors and better eye-hand coordination among others.
