Prokaryotes reproduce asexually by binary fission; they can also exchange genetic material by transformation, transduction, and conjugation.
I positive that the answer id D why because Without<span> them the Earth </span>would<span> be too cold for us, or any other living thing, to survive. Naturally occurring </span>greenhouse gases<span>, such as carbon dioxide and methane, allow solar radiation to reach the Earth's surface, while trapping radiation from the Earth on its way back out to space.
Hope I helped

Answer:
The correct answer will be option-The red and white flower alleles are co dominant.
Explanation:
The Mendel suggested that for any trait, the organism contains its alleles which could be dominant and recessive. But there are cases in which multiple alleles exist for the same trait which are neither dominant nor recessive.
Two cases arise due to this in which both the dominant alleles co-exist and show their phenotype effect called "co-dominance" and when both alleles form a new phenotype called 'incomplete dominance".
In the given case, the self-pollination produces red, white and patched flowers as a result of co-dominance because both the alleles show the equal effect on the flower petals (mixed phenotype) and form a flower with red patches or spots on the flower.
Thus, the selected option is the correct answer.
Scientists claim that Bisphenol A when ingested may cause brain problems, behaviour and reproductive development problems in foetus, children and even infants.
Option D.
Explanation:
Bisphenol A was a very common compound to produce polycarbonate bottles. This bottles were very commonly used to produce baby bottles, different beverage containers, different water bottles etc. Until 2010, BPA was allowed as a safe to consume ingredient by WHO but after 2010,they strictly restricted the levels of BPA in food because it has severe ill effects in human body.
Even low amounts of BPA in food can cause hypertension, coronary heart disease, atherosclerosis etc. Although not proven, but BPA is thought to cause cancer. Effects on children and infants are more prominent which can cause problems in development of reproductive structures and brain. Even in adults, the brain problems may lead to change in their behaviors.
