Unit 5 Describe the two process by which hormones can cause certain genes to be turned on. (4) Any 2 from: - A hormone binds to a receptor in the cell surface membrane - Idea of the receptor causing (chemical) changes inside the cell - A (functional) {second messenger} activates an {enzyme/transcription factor/eq} Any 2 from: - Idea of a hormone entering the cell through the cell membrane - The hormone binds to a receptor - The {hormone-receptor complex/eq} acts as a transcription factor

Animal Research. Animal research is rarely discussed between scientists and animal’s rights activists. If we do not research on animals‚ the world will not develop‚ this means we will not have the things we have‚ we will not have the medicine to people who are sick. Many people will die every day if we do not research on animals. Animal research is important because scientists will learn how to operate‚ also animals are considered like models for human diseases‚ and scientists use animals to create

As Confucius said “Everything has beauty but not everyone sees it” Animals that are hideously ugly‚ Blobfish‚ Aye-Aye‚ Naked Mole Rat‚ Horseshoe Bat‚ Spiders‚ Snakes‚ Vultures‚ Hyenas and many‚ many more are all there for a purpose. Spiders and Bats eat insects and that keeps their population under control. Snakes eat rodents. People think of Vultures and Hyenas as mangy‚ diseased

They were created by a mad scientist and cuddle-buddy lover Dr. Amy Hall‚ a.k.a DNAmy. She is skilled in genetic splicing with a habit of making her own real-life versions of her favorite cuddle-buddies. She captures Mr. Barkin‚ Ron‚ and Ron’s naked mole rat Rufus‚ and she combines Mr. Barkin and Rufus together; it is up to Kim and her dad to save them. In order for DNAmy to combine animals she uses a genetic engineering lab equipped with some sort of splicing machine used to separate the different

This information can be used to calculate other volumes of water by having to multiply it by the number of moles. 5.

In this lab we studied stoichiomentry. We also reviewed the mole-mole relationship between copper and iron in a chemical reaction. The stoichiomentry of mass is that during the heating the experiment does loose mass .This mean that mole and mass did change. An Example of real world is Masses and volumes of products are extremely important in key reactions such as the deployment of air bags in vehicles‚ carbon dioxide production to help bread rise‚ and the Production of ammonia gas for industries

THE MOLE A mole (symbol Mol) is the base unit of quantity of a substance in the metric system. A mole is the quantity of a substance that contains 6.02 x 1023 units. A "unit" is the smallest measurable entity in the substance‚ generally either an atom or a molecule. The number of units in a mole was determined by Italian chemist (a scientist specializing in the composition‚ structure‚ properties‚ and reactions of matter) Amedeo Avogadro (1776-1856)‚ one of the founders of modern physical chemistry

Rats are various medium sized rodents. "True rats" are members of the genus Rattus‚ the most important of which to humans are the black rat‚ Rattus rattus‚ and the brown rat‚ R. norvegicus. Many members of other rodent genera and families are also called rats and share many characteristics with true rats. A rat has an average life span of 2-3 years[1]. Rats are distinguished from mice by their size; rats generally have bodies longer than 12 cm (5 in). Contents [hide] * 1 Species and description
