What effect does burning fossil fuels during manufacturing and energy production have on outdoor air pollution?
Answers
Answer:
It causes global warming as well as air pollution.
Explanation:
Burning of fossil fuels has adverse effect on outdoor air pollution because when the fossil fuels burns carbondioxide gas is released in the atmosphere. Carbondioxide gas is a greenhouse gas which is released in the atmosphere through burning of fossil fuels and is responsible for increasing air pollution. This increase in carbondioxide gas leads to global warming due to blockage of solar radiation that is reflected from the earth surface.

A. 28Km/mins
B. 1.72Km/mins
C. 0.582Km/mins
D. 106 Km/mins
Answers
Answer:
B. 1.72Km/mins
Explanation:
The topic is Mathematics, not Biology but okay!
All you have to do is 67/39 which equals 1.72km/mins.
This is because you have to work out the average speed in kilometres per minute. 39/39 = 1 minute

The greatest amount of genetic variation is produced in offspring that reproduce -
A. sexually through fission B. asexually through budding C. sexually through meiosis D. asexually through mitosis
Answers
In meiosis, the greatest amount of genetic variation is produced in offspring that reproduce sexually, hence option C is correct.
How do organisms reproduce sexually through meiosis?Because the environment is continually changing, sexual reproduction often has an advantage over asexual reproduction.
Increased phenotypic variation, or the physical variety of the organisms, results from higher genetic diversity.
Each gamete has a unique DNA set because of recombination and independent assortment during meiosis. The resultant zygote has a special set of genes as a result.
Genetic variety can be increased by new genes and alleles being created as a result of gene duplication, mutation, or other events.
Therefore, it is possible for novel gene combinations to arise during sexual reproduction.

Condensation is a process in which water vapors changed into liquid state.
Explanation:
Condensation is a process in which water that is present in the vapors form changed into liquid state. Condensation greatly affect Earth systems because this process is responsible for the precipitation on the earth. Condensation occurs in the atmosphere when warm air rises in the atmosphere, cools and unable to hold water vapor. As a result, water vapors condenses to form cloud droplets that falls in the form of rainfall.

how would this affect the cells made from the cell cycle? passage: timmy has a disease that effects his cell cycle, it causes the S phase (part of interphase) to not work correctly.
Answers
Answer:
No cells are produced.
Explanation:
If the S phase of cell cycle did not work properly, the cells produced are abnormal or no cells are produced because no extra copy of chromosomes are present for cell division. If there is no extra copy of chromosomes is present in the cell, the cell will not go to the G2 phase and as a result the cell cycle is remain incomplete. So that's why we can say that no cells are produced if S phase did not work properly.
