1-2 Paragraphs About The Background Of Reaction Time Slowing Down Once You Get Older

Biology
1 answer:
lesya692 [45]3 years ago
8 0

Answer:

Reaction times slow with age, and they correlate with scores on tests of higher cognitive functions many of which also deteriorate with age. The age-related changes in reaction times account for a substantial proportion of the age-related variance in higher cognitive functions (e.g., Deary, 2000. 2000Reflexes do slow with age. Physical changes in nerve fibers slow the speed of conduction. ... But the effect of age on reflexes and reaction time varies greatly from person to person. You can actually slow down—even reverse—the effects of aging by staying physically active.The next time some twenty-something complains that they feel old, you can reassure them that their feelings are, in fact, not ridiculous. After studying 3,305 people ages 16 to 44, researchers found that the brain's response time begins to decline at age 24.

Explain how the energy investing and energy harvesting steps of glycolysis result in 2 ATP molecules.
Anna [14]

Answer:

There are two-phase of glycolysis preparatory phase and payoff phase. In the preparatory phase, ATP is used therefore it is called the energy investment phase and in the payoff phase, ATP is produced so it is called the energy generation phase.

In preparatory phase 2 ATP is used and it is converted into ADP and in pay off phase 4 ATP is produced from ADP. Therefore by subtracting 2 from 4, we get 2 ATP. Therefore in glycolysis, energy investing and energy harvesting step results into two ATP molecules.

Cephalopods have complex eyes that arose separately from vertebrate eyes that are also used in vision. what's this illustration
juin [17]

Options:

A. Analogous structures

B. Vestigial structures

C. Homologous structures

D. Missing links

Analogous structures is the illustration in cephalopod. Thus, the correct option is C.

A cephalopod eye, unlike a vertebrate eye, is focused through movement, similar to a camera or telescope lens, rather than altering shape like a human eye lens. The lens, which is totally internal, is nearly spherical, as is the eye.

<h3>What are the characteristics of cephalopod?</h3>

  1. Organs. They have three hearts, two of which transport blood to the gills and the other which pumps blood throughout the body. Their blood is blue because the protein hemocyanin binds oxygen.
  2. Color. Cephalopods have the ability to change the color of their skin at will. They can even use their skin to create elaborate patterns and forms. This is accomplished by the use of chromatophores, which are pigment-filled bags found in the skin. Nerves can change the color of the skin by controlling these chromatophores.
  3. Diet. Cephalopods are all carnivorous animals.

Organs, tissues, or cells in the body that are no longer functional in their ancestral version of the trait are known as vestigial organs.
