Prion disease is a protein that can affect the brains protein. People can get it through family history or its passed on through the genes, those who ate a cow infected by mud cow disease and infections from medical equipment. I hoped this helped.
The remains of plants and animals preserved in the earth => fossils
coal, oil, natural gas => fuels
fossil fuels
Answer:
Duplication of hox genes is important in the radiation of animals because they are regulating genes of symmetry and the body plan of the animals' bodies. Some change or mutation in these genes during duplication can cause mutations and with these evolution of the species as it controls the different segments of these animals as they develop, launching the genetic programs that form various body structures, such as limbs and organs. .
Answer:
A)Biomass is transferred from one organism to another when one organism consumes another organism. When a predator organism eats the prey organism, the molecules on the food are broken down by the digestive system into smaller molecules. These smaller molecules like lipids, amino acids, glucose are used by the organism for various purposes.
B) Energy that is not transferred from one organism to another is either used up by the organism for various purposes. Most of the energy is lost into the environment in the form of heat.
c) There are typically fewer organisms at the top of the trophic levels because energy keeps on declining at each trophic levels so the number of consumers which it can satisfy also decreases.
d) Only 10% of the energy passes from one trophic level to another. The rest is usually lost in the form of heat. For example, if there was 100% energy in the producers, only 10% would pass to the primary consumers. The secondary consumers will receive 1%.
Answer: The answer is that the phenotypic ratio among phenotypes produced from an F1 X F1 dihybrid cross is 9:3:3:1.
Explanation:
Independent assortment of genes explains how alleles on different chromosomes arrange independently of one another during gamete formation.
So, a dihybrid cross involving TWO characters (e.g Seed color & seed shape) would have its respective alleles DISTRIBUTED whether dominant or recessive, for crossing to occur and yield varying proportion of offspring in the well spread ratio of 9:3:3:1; making it a consequence of independent assortment of genes
