The correct answer is D ie. a mutation resulted in a new color of insect.
A mutation is a change in a gene's structure, which is how inheritance works. Deoxyribonucleic acid (DNA), a lengthy molecule made up of units referred to as nucleotides, is the substance that makes up genes. Each nucleotide is constructed around one of four distinct bases.Due to population genetic variability, the population of lady beetles has changed over the generations (also called genetic diversity).The color gene of insect carapaces is the gene that has undergone diversification in this instance. In this example, there are two alleles (one for the green color and the other for the yellow color).Hence , the answer to this question is option D

In the case of sickle cell anemia, the slight alterations in the DNA of red blood cells lead to a. defects in the membranes of these cells. b. changes in the structure of the protein hemoglobin. c. poor use of glucose for energy. d. inability of the cells to make protein.
The slight alterations in the DNA of red blood cells lead to changes in the structure of the protein hemoglobin.
What is sickle cell anemia?Sickle cell anemia refers to a defect in the red blood cells in which abnormal hemoglobin is present in the red blood cells resulting in the inability of the red blood cells to efficiently transport oxygen to the tissues.
This is due to a mutation in the gene coding for hemoglobin production.
The red blood cells have a sickle shape.
Therefore, the slight alterations in the DNA of red blood cells lead to changes in the structure of the protein hemoglobin.

Saturn is close to Polaris during some years
true or false
Saturn is not close to polaris
Polaris disappears into the horizon as seen from the equator, and is not visible from the south of the equator. Finding Polaris in the Northern Hemisphere indicates that you are aware of the direction north.
What is the importance of Polaris?Directly above Earth's North Pole is the Pole Star, or Polaris. Due to its location over the North Pole, the pole star is aligned with the earth's axis. As the sole star that is stationary, it is crucial for orientation.
It makes a fairly small circle over the course of a day since it is so close to the celestial equator. As a result, Polaris is a trustworthy indicator of north, since it always remains in nearly the same location in the sky.
Therefore, it is false that Saturn is close to Polaris during some years.

A microbiologist has a bacterial culture with 100,000 cells per mL of nutrient broth, but needs to dilute the culture with sterile nutrient broth to 1,000 cells/mL. To accomplish this, the microbiologist should dilute 1 mL of the culture to what total volume, in mL?
A. 10
B. 90
C. 100
D. 1, 000
PLEASE EXPLAIN ASAP
To accomplish the dilution the microbiologist should dilute 1 mL of the bacterial culture in 100 mL of the total volume. Thus, option C is correct.
What is dilution?Dilution is a process of decreasing the solute concentration by the addition of the solvent in the solution. The volume for the dilution is calculated as:
Given,
C1 = 100,000 cell per mL
C2 = 1000 cell per mL
V1 = 1 mL
C1 V1 = C2 V2
100,000 × (1 ÷ 1000)

Comparable segments of the mitochondrial DNA sequences of two similar species are shown below. This segment of DNA mutates at a rate of two base pair per 330,000. years. The DNA sequences for Species A is CTGTCCGAAG and Species B is CTGTCCGTCG. How many years ago did these species diverge from a common ancestor? 660,000 years ago
33 years ago
330,000 years ago
6,000 years ago
The homo-logous mitochondrial sequences CTGTCCGAAG and CTGTCCGTCG suggest that species diverge from a common ancestor 660,000 years ago.
What is the mutation rate?The mutation rate indicates the number of nucleotide differences between two homo-logous sequences that emerged in evolution in a given period of time.
In this case, the mutation rate is one nucleotide per 330,000 years and here we have two mutations (CTGTCCGAAG and CTGTCCGTCG), thereby it is expected that the sequences diverged 660,000 years ago.

Explain why the biodegradation of plastic might be more hazardous to the environment than the presence of plastic as marine debris.
Answer:
they generate a large amount of macrobiotic flora which can cause diseases to humans as well as animals
Answer:
While plastic is not generally considered biodegradable, it can be broken down by the action of photodegradation and certain microbes. The breakdown products of plastic, however, are extremely toxic to marine life and once the plastic breaks down they are free to enter into the food chain. Therefore, while plastic marine debris is hazardous and dangerous to marine organisms, the toxic breakdown products of plastics have the potential to do even more damage.
