The kidneys can regulate water levels in the body; they conserve water if you are dehydrated, and they can make urine more dilute to expel excess water if necessary.
When Earth passes directly between the Sun and the Moon, its shadow creates a lunar eclipse. Lunar and Solar eclipses happen with almost the same amount of frequency. Lunar eclipses are more visible because the Earth casts a bigger shadow on the Moon during a Lunar eclipes, but during a Solar eclipes the Moon casts a bigger shadow on Earth so its less visible.
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.
Answer:
Nuclear lamins will no longer disassemble during mitosis
Explanation:
The nuclear lamina is a fibrillar network inside the nucleus of eukaryotic cells, between the inner nuclear membrane and the peripheral chromatin. Nuclear lamins (also called simply lamin proteins) are intermediate filament-type proteins and represent the major building blocks of the nuclear lamina. During mitosis, the nuclear lamina is disassembled by hyperphosphorylation of nuclear lamins and lamina-associated proteins. The protein responsible for phosphorylating nuclear lamins is p34cdc2, a protein kinase that has a key role in controlling cell cycle progression. In consequence, a mutant form of the nuclear lamin proteins that cannot be phosphorylated will no longer be able to disassemble during mitosis.
