Answer:

Option). Increasing enzyme, increasing substrate, increasing co-factors

Explanation:

Enzymes are bio-catalysts that increase the rate of a chemical reaction by decreasing its activation energy. As enzymes are catalytic molecules, increasing enzyme concentration would increase rate of reaction.

Substrates are those substrates that react with other molecules to form products. Thus, increasing the concentration of substrates, along with enzymes to an enzyme-catalyzed reaction would increase rate of that reaction.

Co-factors are non-protein compounds or ions, which are required for proper functioning of many enzymes. Thus, increasing the concentration of co-factors, along with enzymes to an enzyme-catalyzed reaction would increase rate of that reaction.

Thus, the correct answer is option). 'increasing enzyme, increasing substrate, increasing co-factors.'

If the DNA sequence TTCACG is transcribed to AAGGC, what type of mutation has occurred?

kenny6666 [7]

The answer is d. deletion.

If the DNA sequence is TTCACG, it is expected to be transcribed into AAGUGC.
But, it was transcribed into AAGGC. If we count nucleobases, a transcribed sequence has 5 nucleobases, while DNA sequence has 6 nucleobases. These means that deletion happened.
If insertion occurred, there will be 7 nucleobases in transcribed sequence. In substitution or translocation, the transcribed sequence will be the same size, but with different sequence than the DNA sequence.

The Southern Oscillation is in a negative phase when pressures are: Group of answer choices low in both Tahiti and Darwin equal

MArishka [77]

The Southern Oscillation is in a negative phase when pressures are higher in Darwin than in Tahiti.

The Southern Oscillation Index (SOI) is a standardized index that is derived from the observed changes in sea level pressure (SLP) between Tahiti and Darwin, Australia. This index is used to predict future weather patterns. During El Nio and La Nia events, the SOI is one measurement of the large-scale fluctuations in air pressure that occur between the eastern and western tropical Pacific. These changes can be attributed to the Southern Oscillation. In general, when time series of the SOI are smoothed, a very good correlation with variations is seen in the temperatures of the oceans throughout the eastern tropical Pacific. The negative phase of the SOI indicates that the air pressure in Tahiti is lower than normal while the air pressure in Darwin is higher than normal. Extended periods of negative Southern oscillation index values coincide with ocean temperatures over the eastern tropical Pacific that are abnormally warm (cold), which is typical of El Nio (La Nia) events.

victus00 [196]

Answer:

The given blank can be filed with stasis.

Explanation:

There are various kinds of species that have been discovered in the world and had remained unmodified, that is, right from the start. This has been supported by their fossil records that in the geological strata they were witnessed unchanged. This phenomenon is termed as stasis, in which the species do not exhibit any kind of directional change. The starfish, lungfish, and the tribolates belong to this category, that is, their current time appearance is identical to the fossil records.

What genetic variation has occurred in the picture below where a black bunny and a white bunny have an offspring that shows both

Softa [21]

<h2>Answer:</h2>

The correct answer is B which is codominance.

<h3>Explanation:</h3>

One allele of a gene for a trait can be dominant or recessive according to the simple genetic phenomenon.
But there are some exceptions Like both allele can express them dominantly producing an offspring having both forms of that trait.
While in incomplete dominance, dominant allele is unable to expresses itself completely and a phenotype between dominant and recessive trait is produced.
Hence in the problem, offspring have both colors of fur from two parents, so it is codominance.
