Answer:

c. A single enzyme typically reacts with many different substrates.

Explanation:

Enzymes are proteins that have catalytic activity and they are specific. This means that a single enzyme has only one specific substrate. They act as a "lock and key" complex, so one substrate activates to one enzyme.

Also, enzymes accelerate the rate of a reaction by lowering its activation energy. Finally, they can act in an aqueous environment, so the answer is c.

Go to biology.arizona.edu They have a ton of stuff on blood types. I don’t know if this will help because I’m not in biology yet but I’ve been there and it helped a lot with some stuff. Hopefully that didn’t sound to vague. Have a wonderful day.

For two autosomal dominant genes, what is the probability that a cross between two heterozygotes (i.e. AaBb x AaBb) will produce
oksian1 [2.3K]

Answer:

1 in 16

Explanation:

When two heterozygotes (AaBb x AaBb) for two autosomal genes are crossed the expected probability for the offspring is 9 A-B-, 3 A-bb, 3 aaB- and 1 aabb. In other words, out of sixteen offspring, 9 are expected to be dominant on both genes (either homozygous AA or BB or heterozygous Aa or Bb), 3 are expected to be dominant on the A gene but recessive on the b gene, 3 are expected to be recessive on the a gene but dominant on the A gene, and only 1 is expected to be recessive on both genes aabb.

Brian goes to the hospital after not feeling well for a week. He has a fever of 38 °C (100.4 °F) and
Cloud [144]

Answer:

The signs would be his fever/high temperature. The symptoms would be his feelings of nausea and migraine.

Explanation:

Where a symptom is subjective, as in apparent only to the patient (for example back pain or fatigue), a sign is any objective evidence of a disease that can be observed by others (for example a skin rash or lump).

A 300-N force acts on a 25-kg object. The acceleration of the object is ____. options: 7500 m/s2 300 m/s2 25 m/s2 12 m/s2
Jet001 [13]

Answer:

the answer is 12 m/s2

Explanation:

To solve the answer use the equation: a = fnet / m

a = 300 N / 25 kg

300 N / 25 kg = 12m/s

The acceleration of the object is 12m/s
