Oxygen is essential for many forms of life, yet early earth had very little oxygen in the atmosphere. Where did the increase in oxygen come from?.
Answer:
Literally, it is the waste product of cyanobacteria, also known as blue-green algae.
EXPLANATION
Explanation:
Between two to three billion years ago, Earth's atmosphere started changing.
Organisms living then were doing so anaerobically (without oxygen), but there was a gradual build up of oxygen in the atmosphere - the reason for this, as well as for the percentage of oxygen stabilising at around 21% is still unclear.
What we do know is that tiny organisms known as cyanobacteria (or blue-green algae) would photosynthesise carbohydrates for their nutrition and growth using sunlight, water, and carbon dioxide.
The waste product of photosynthesis, till today, is oxygen.
Over time, this oxygen increased till it reached the levels that we experience today.
The chloroplasts in today's plants are symbiotic cyanobacteria that continue the same process started billions of years ago.

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.

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.

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.
