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.
Explanation:
which two products are bromelain likely to produce when breaking down proteins
amino acids
fatty acid
monosaccharides
nucleic acid
polypeptides
disaccharides
The two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.
What are proteins?Proteins are a major group of biological macromolecules composed of a linear chain of aminoacids that are linked by means of peptide bonds.
Proteins are fundamental macromolecules present in all biological systems and they can be made by one or more polypeptides in order to form molecules that exhibit primary, secondary, tertiary, and quaternary structures.
These macromolecular structures can be evidenced by the tridimensional shapes that adopt different proteins, which can be globular or fibrous.
In conclusion, the two specific products that bromelain produces when breaking down proteins are polypeptides and amino acids.

Similarities in Aemoba and Humans
Answer:
Both Amoeba and human beings are heterotrophs and derive nutrition from other organisms. Dissimilarity: Human beings have a complex digestive system and different nutrients are digested in separate regions. Amoeba does not have a digestive system and all the nutrients are digested in the food vacuole.

What is Cellular Respiration and what is the formula for it?
Answer:
Summary. Aerobic respiration is the aerobic catabolism of nutrients to carbon dioxide, water, and energy, and involves an electron transport system in which molecular oxygen is the final electron acceptor. The overall reaction is: C6H12O6 + 6O2 yields 6CO2 + 6H2O + energy (as ATP).

Answer:
Proteins
Explanation:
Enzymes are an example of a class of organic compounds called proteins.
PROTEINS:
Proteins are one of the four major biological molecules in nature (others being carbohydrates, lipids and nucleic acids). Proteins play vital roles in living organisms, which includes regulating biochemical reactions, repair of structures etc. Enzymes are biological catalysts that helps to regulate the rate of a reaction. Enzymes are proteinous in nature i.e. they are made of proteins.

In mice, there are three options for fur color: black,grey and white. What type of inheritance is shown by these mice?
A. Simple
B. Co-dominance
C. Incomplete dominance
D. Sex linked inheritance
Answer:
C. Incomplete dominance
Explanation:
Incomplete dominance is a type of non-mendelian inheritance in which one allele does not completely mask the phenotypic expression of the other allele in a gene, hence, the blending of both alleles give rise to an intermediate third phenotype.
According to this question, there are three options for fur color in mice namely: black, grey and white. This is so because the alleles for black and white coloration exhibits INCOMPLETE DOMINANCE, hence, they produce a third phenotype (grey) that is a blend of both parental phenotypes.
What was the health of the ecosystem of Atlas National Park like before wolves were reintroduced? *WILL GIVE BRAINLIEST*
Answer:
the populations of their prey—the deer, rabbits, and so on—may increase due to a lack of at least one natural predator.
Explanation:
Wolves are causing a trophic cascade of ecological change, including helping to increase beaver populations and bring back aspen, and vegetation. Today, nearly 25 years after wolves were reintroduced into the park, the top predators have helped parts of the ecosystem bounce back. They've significantly reduced elk herds, opening the door for willow, aspen, beaver and songbird populations to recover.
The health of the ecosystem is not good due to imbalance conditions.
The health of the ecosystem of Atlas National Park is not good before the introduction of wolves because the population of herbivore such as deer increases which leads to the destruction of all vegetation present in the park as a result the park health deteriorates.
When the wolves are introduced in the ecosystem, they controls the population of herbivores i.e. deer that feeds on the grass and the recovery of vegetation that was lost due to herbivorous animals occur so we can conclude that the health of the ecosystem of Atlas National Park is not satisfactory before wolves were reintroduced in the park.

Why is there Cholesterol in your cell membrane?
Answer:
Cholesterol functions to immobilise the outer surface of the membrane, reducing fluidity. It makes the membrane less permeable to very small water-soluble molecules that would otherwise freely cross. It functions to separate phospholipid tails and so prevent crystallisation of the membrane.

how many codons equal one amino acid
Explanation:
hope the answer was helpful
Three codons equal one amino acid
CODON:
A codon is a nucleotide sequence consisting of three bases. The genetic code is read in a group of three nucleotide bases at a time, which are called codons. Each codon encodes an amino acid. For example, codon AUG encodes methionine amino acid. Each codon is read during translation to form an amino acid sequence. This means that the number of codons in a mRNA (nucleic acid) sequence determines the number of amino acids in a sequence. Therefore, three codons equal one amino acid.Learn more at: https://brainly.com/question/14136689?referrer=searchResults
