Answer:
Cell growth but also involved in cancer development
Explanation:
Tyrosine-kinase receptors are the main receptors for the growth hormones, but also cytokines and hormones. These receptors are regulators of normal cellular processes, but if a mutation occurs it can lead to activation of a series of signalling cascades that change the gene expression. Consequently, this has a critical role in the development and progression of many types of cancer.
<span>In order to understand trans fat, you must understand the prefix. Trans and cis are prefixes that mean opposite and same side, just like transgender people identify with a gender that is not in line with their biological sex, and cisgender people identify with their biological gender. Cis fat describes the fatty acids attached to the glycerol in triglycerides. Cis fats have hydrogen attached to the carbon chain just like trans fats, but at one, two, or more places on the chain, two hydrogen atoms attached on the same side, and the fatty acid chain gets bent, making the collection of fats less dense and therefore healthier for you and I. Trans fats have hydrogen atoms on alternating sides all the way down the chain, making them denser and solid at room temperature. In order to turn a plant oil (cis fat) into trans fat, the cis fat has to be blasted with hydrogen in order to turn the fatty acid chains from cis to trans. This adds more energy to the fats while also making them denser, which turns olive oil into a butter-like substance.</span><span />
The cell theory is fundamental to all living things.
Fossils up to 75,000 years old can be dated with Carbon-14.
Radio isotopes can be used for the age determination of the fossils. Carbon-14 is a common isotope which is used for that purpose. But the half- life of the Carbon-14 is relatively small as 5730 years. That means the amount of Carbon-14 will be half after every 5730 years. Hence, decay is very fast. So Carbon-14 cannot be used forage determination which is more than 75000 years due to the low accuracy.
