Answer:
The animals of the Earth and their environment the history of life on Earth how people and animals interact and live how living organisms interact and function Biology answers many questions, but its main focus is how living organisms interact and function.
Explanation:
Biology is the subject focused on the study of living organisms.
Biology, as a scientific discipline, primarily focuses on the study of living organisms and their interactions with the environment. Its main objectives include understanding the processes of life, such as growth, reproduction, adaptation, and evolution. Biology seeks to unravel the complexities of cells, genetics, physiology, and ecosystems, aiming to explain how living organisms function at various levels, from molecular to ecological.
While it addresses diverse questions, its central focus is to elucidate the mechanisms underlying life, biodiversity, and the interconnectedness of all living things, providing insights into how life forms have developed and continue to thrive on Earth.

B. Mutation
C. Independent assortment
D. Random fertilization
E. All of the above
Answer:
The correct answer is E. All of the above
Explanation:
Variation in offspring can be contributed by many different events that change the DNA sequence in gametic cells. These events are crossing over, mutation, independent assortment, and random fertilization.
During the gamete formation, the different genes are assorted independently from the other gametes which results in forming various possible combinations of genes in a gamete increasing the genetic variation.
Crossing over occurs during meiosis between the homologous chromosome that results in exchange of genetic material that brings genetic variation in gametes. During random fertilization, the two gametes fuse and genetic material of two different individual comes to make an offspring which forms a genetical different offspring.
Mutation in the gametic cell is transferred to the offspring during fertilization. Therefore all contributes to variation in offspring produced by sexual reproduction.
Answer:
b) food
Explanation:

Ans.
Carbon is one of the four most important atoms found in cells of all living organisms and is a major constituent of biomolecules, such as carbohydrates, proteins, and fats.
When the deer is killed and eaten by the mountain lion, its dead remains are eaten by some other animals, such as vultures, jackals, and wild dogs.
These organisms that feed on dead organisms are known as scavengers. Hence, the carbon present in deer carcass would be incorporated into scavengers.
Thus, the correct answer is 'option). B.'
The answer is a. It would be incorporated into other organisms.
Answer:
B) genetically modified.
Explanation:
Genetically modified foods are foods that are produced from organisms with DNA that has been modified through genetic engineering. This results in food that is more appetizing, more high-yielding or more resistant than food that has not been modified. This type of food is created in such a way in order for breeders to have better control over the positive traits of the organisms. These methods are similar to the more traditional selective breeding and mutation breeding.
Answer:
The answer is C. The GPS makes a task easier
Answer:
Its C
Explanation:
Answer:
Sample A: 21.3%A, 28.7% G and 28.7% C
Sample B: 27.7% A, 22.3% G and 22.3% C
Explanation:
According to Chargaff's rules of base pairing, the amount of adenine in a DNA molecule equals the amount of thymine, and the amount of G=C.
Sample A
Contains 21.3% T, so it also contains 21.3% A. Therefore A+T= 42.6%
100% - (A+T) = (G+C)
100% - 42.6% = 57.4%
G+C add up to 57.4% of the DNA in sample A. And because G=C, there's 28.7% G and 28.7% C.
Sample B
Contains 27.7% T, so it also contains 27.7% A. Therefore A+T= 55.4%
100% - 55.4% = 44.6%
G+C add up to 44.6% of the DNA in sample B.
And G=C, so there's 22.3% G and 22.3% C.
