Which process occurs when two haploid (N) nuclei fuse and a single diploid (2N)
nucleus is formed?
implantation
mitosis
fertilization
meiosis
Answer:
c. fertilization
Explanation:
Fertilization is the process when two haploid (N) nuclei fuse and a single diploid (2N) nucleus is formed. Therefore, option C is correct.
What is fertilization?Fertilization is the process by which a sperm cell from a male fuses with an egg cell from a female to form a zygote. In most organisms, including humans, fertilization occurs during sexual reproduction.
The zygote contains a unique combination of genetic information from both the mother and the father and will develop into an embryo, which will eventually grow into a fetus. Fertilization is a critical step in sexual reproduction, as it initiates the development of a new organism with its own unique set of genetic characteristics.
Thus, fertilization is the process when two haploid (N) nuclei fuse and a single diploid (2N) nucleus is formed. Therefore, option C is correct.

what percentage of the water entering the small intesneine is not absorbed during the digestive process
The 10% of the water entering the small intestine is not absorbed during the digestive process.
What is the Digestive process?The digestive process may be defined as a type of process that significantly deals with the organs that take in food and liquids and ultimately break them down into simpler substances so that the body can utilize them for energy production, growth, and tissue repair.
It may be thought that 90% of the water entering the small intestine is absorbed during the digestive process. This percentage of absorbed water constitutes either liquid or solid food. Apart from this, 95% of the carbohydrates and protein you consume are absorbed in the small intestine during the same process.
Therefore, 10% of the water entering the small intestine is not absorbed during the digestive process.

Driving while sleep impaired is much safer than driving while intoxicated. Please select the best answer from the choices provided T F.
Answer:
false but both are unsafe
Explanation:
Driving while sleep-impaired is not safer than driving while intoxicated. In fact, it is just as dangerous, if not more so. Hence the statement is false.
Driving while sleep-impaired is a serious problem that can lead to accidents, injuries, and even death. When you are sleep-impaired, your reaction time is slowed, your judgment is impaired, and your coordination is decreased. These factors can all contribute to dangerous driving behaviors.
A study by the National Highway Traffic Safety Administration (NHTSA) found that drivers who are sleep-deprived are 7 times more likely to be involved in a fatal crash than drivers who are well-rested.
The study also found that drivers who are sleep-deprived are more likely to make mistakes, such as drifting out of their lane or failing to yield the right of way.
Therefore, the statement "Driving while sleep impaired is much safer than driving while intoxicated" is false.

Check the three factors that influence population growth. A. Increasing Longevity B. International Migration C. Fertility Rates D. Social media use E. Water supply.
Population growth is the increase in the population number of a given species in a time. Longevity, migration and fertility rates affect population growth.
What are the factors affecting population growth?Increased Longevity has impacted the population growth as the life expectancy has resulted in the accumulation of more people as their age of living has increased.
International Migration can affect the population growth positively and negatively as moving of the person from one region will decrease its population growth while the region where they go will have increased population.
Fertility Rates has a great impact on the population as the fertility rate had decreased due to many factors and the population has declined.
Therefore, option A. longevity option B. migration and option C. fertility rates influence the population growth.
