A molecule that can be used as a molecular clock has a neutral mutation rate of one mutation per 12 million years. How many years ago did two species share a common ancestor if the molecules found in these two species differ by a total of six mutations?
a 1.5 million years
b 72 million years
c 12 million years
d 36 million years
The years in which two species share a common ancestor if the molecules found in these two species differ by a total of six mutations is 72 million years.
What is mutation?Mutation is the changing of gene or characters of any species over time, there are many reasons for mutation, like natural selection.
Every 12 million years, the molecular clock will mutate.
If the molecular clock experiences six mutations, 12 million years multiplied by 6 have passed.
12 x 6 = 72
Thus, the years are 72 million years. Option is b.

Which pattern is caused by fire burning upward
Pour patterns
V-pattern
Rundown pattern
Inverted cone
Please only answer if you know
V-pattern caused by fire burning upward. Thus, the correct option is B.
What do V patterns in burn mean?V-Patterns: Because fire burns up in a V-shape, a fire that starts at an outlet next to a wall will leave a char pattern that will help identify the source. A fire that is hotter than usual, such as one aided by an accelerant, may have an extremely narrow V-shape.
The observable or quantifiable physical changes or recognisable shapes produced by a fire effect or combination of fire effects are known as fire patterns, sometimes known as burn patterns. The changes that occur in or on a substance as a result of exposure to fire are known as fire effects.

A. Describe how the biomass in the bluegill fish trophic level of a biomass pyramid would be
different from the biomass in the aquatic plants trophic level of the same pyramid.
The biomass would be different because aquatic plants are producers while bluegill fishes are consumers.
Pyramid of biomassIn a food chain or food web, the biomass of the population of organisms at the lower trophic levels is usually more than that at the higher trophic level.
Thus, producers tend to have more biomass than primary consumers. Primary consumers tend to have more biomass than secondary consumers.
In the same vein, secondary consumers have more biomass than tertiary consumers.
Bluegill fishes are consumers while aquatic plants are producers. Thus the biomass of aquatic plants would be more than that of bluegill fish.

Which of the following are complementary pairs in DNA:
True
False
Answer:
B) C - G
Explanation:
There are only 2 complementary bases in DNA which are:
A - TC - GYou are a mosquito and your body cells have 3 pairs of chromosomes, giving you a total (diploid) number of 6 chromosomes. After mitosis, how does the number of chromosomes in the daughter cells compare to the number of chromosomes in the parent cell? Why is this important?
At the beginning of mitosis, a mosquito cell has six double-stranded chromosomes. This cell will have split into two daughter cells with six chromosomes each at the end of mitosis. Consequently, 6 chromosomes will be provided to each daughter cell (single-stranded).
What is mitosis?One cell divides into two genetically identical daughter cells during the cell duplication process known as mitosis. The cell's chromosomes are duplicated throughout the process of mitosis and then divided equally between the two daughter cells' two new nuclei.
Every chromosome acquires identical copies of the parent cell's DNA thanks to anaphase. At their centromere, the sister chromatids divide in half to form distinct, identical chromosomes.

different between seed method and biological method of breeding
please help
Answer:
Plant breeding is the purposeful manipulation of plant species in order to create desired genotypes and phenotypes for specific purposes. Plant genetic is is the study of genes, genetic variation, and heredity specifically in plants.
The seed method involves selecting plants with desired traits and breeding them to produce offspring with those traits and the biological method involves using mutation breeding, tissue culture, and genetic engineering to create new plant varieties.
What is seed and biological methods of breeding?The seed method and the biological method of breeding are two approaches that are used to develop new plant varieties.
The seed method involves selecting plants with desired traits and breeding them to produce offspring with those traits. This can be done through various techniques, such as crossbreeding, inbreeding, and hybridization. The seed method relies on the transfer of genetic material through the seed, and it is often used to develop new varieties of crops that are well suited to specific growing conditions.
The biological method of breeding involves using techniques such as mutation breeding, tissue culture, and genetic engineering to create new plant varieties. This approach involves altering the genetic makeup of plants in order to introduce new traits or to enhance existing ones. The biological method can be more precise and faster than the seed method, but it also involves more complex techniques and may be more expensive to implement.
