The fact that at least one species of resistant bacteria has developed for almost every antibiotic is evidence of which condition?A. The bacteria have adapted and could be evolving into a different species.
B. The bacteria have learned to mimic other species.
C. There is no variation in the bacteria population.
D. The antibiotics are made differently.

Answers

Answer 1

Answer: Let us take logic into consideration although it is not so obvious.
The answer is A, because they have actually adapted. It is less likely to be B, because they cant mimic other species.
Now of course C and D are out:
reason being is that there must be variations in the bacteria population and antibiotics are never made differently.

When viewing a human karyotype to detect genetic disorders, which situation would indicate a genetic problem?A) two X chromosomes
Eliminate
B) three chromosomes in any one set
C) twenty-three pairs of chromosomes
D) different chromosomes of different lengths

Answers

The answer is B) three chromosomes in any one set.

In a human diploid somatic cell (2n), there are 22 chromosomes present in two copies and 1 pair of sex chromosomes. This means there are 23 pairs of chromosomes (so choice C. does not indicate a genetic problem). There are in total 46 chromosomes (23 pairs in 2 copies), that differs in lengths (so choice D. does not indicate a genetic problem). Speaking of a pair of sex chromosomes, there could be two X chromosomes in females or one X and one Y chromosome in males (so choice A. does not indicate a genetic problem).
But, having three chromosomes in any one set suggests a presence of trisomy, which is a condition in which an extra copy of some chromosome is present. This results in a genetic disorder.

An enzyme is a biomolecule that increases the rate of a chemical reaction. An enzyme is a kind of _______.A) catalyst
B) translator
C) ribosome
D) inhibitor

Answers

An enzyme is a biomolecule that increases the rate of a chemical reaction. An enzyme is a kind of A. catalyst. A catalyst increases teh rate of chemical reaction by decreasing the activation energy which lowers the barrier of getting the chemical reaction to take place. Enzymes are often reffered to as biological catalysts

Straps fastened around a horse's legs to restrain their movements are called A. twitches.
B. hobbles.
C. leashes.
D. halters.

Answers

The correct answer is option B

The straps or spancel is a device which is used to limit the walk of the animals like horses, donkeys, et cetera.

This device tethering one or more legs together to limit their movement so that they cannot go far away. It is mostly used in horses.

Sometimes hobbles are used on other animals when they are trained to stay still in a particular position.

B. hobbles. Think of the definition of "to hobble." It's means to have difficulty walking. Hopefully that will help you remember.

Distinguish between gradualism and punctuated equilibrium.

Answers

For gradualism changes in species is slow an gradual, occurring in small period changes in the gene pool, whereas for punctuated equilibrium, evolution occurs in spurts of relatively rapid change with long periods of non- change.

Final answer:

Gradualism and punctuated equilibrium are evolutionary theories. Gradualism suggests a slow, constant pace of evolution, whereas punctuated equilibrium involves rapid speciation events after periods of stability.

Explanation:

The theory of gradualism posits that evolution proceeds gradually, with slow and continuous changes taking place over long periods of time. Species progressively mutate and adapt, leading to gradual phenotypic and genetic changes, eventually resulting in some new species over millions of years.

On the other hand, punctuated equilibrium proposes that species experience long periods of stability (equilibrium), punctuated by short, rapid events of speciation. These dramatic events involve a small segment of the population evolving quickly while the rest of the population remains unchanged, leading to a new species.

In summary, gradualism presents a slow, steady pace of evolution, while punctuated equilibrium supports the theory of sudden evolutionary jumps interspersed with periods of little to no evolutionary change.
