Answer:
The rock cycle is a basic concept in geology that describes transitions through geologic time among the three main rock types: sedimentary, metamorphic, and igneous. Each rock type is altered when it is forced out of its equilibrium conditions. For example, an igneous rock such as basalt may break down and dissolve when exposed to the atmosphere, or melt as it is subducted under a continent. Due to the driving forces of the rock cycle, plate tectonics and the water cycle, rocks do not remain in equilibrium and change as they encounter new environments. The rock cycle explains how the three rock types are related to each other, and how processes change from one type to another over time. This cyclical aspect makes rock change a geologic cycle and, on planets containing life, a biogeochemical cycle.
Hi
The term lack of genetic diversity for a particular population refers to the fact that there are less number of alleles and less range of phenotypes and traits like (height, skin, color, ability to cope disease, ability to change metabolism as per requirement etc).
If we talk about endangered species, they are the specie which are prone to be extinct in near future because their population is very less in number. There can be multiple reason of becoming endangered for a population such as over hunting etc.
So when we say that an endangered population is genetically less diverse, it means that there are further difficulties that hinder their recovery.
For example: If a calamity stucks, all organisms that are already low in number and also genetically less diverse, so they cannot cope with calamity and get extinct. However, if this population is genetically more diverse, some organisms may survive some may die, and those which survive can recover the population. That is why it becomes more difficult to recover an endangered specie if it is genetically less diverse. The more the genetic diversity, better it is for specie.
Hope it help!
<span>A codon is a tree letter nucleotide sequence that represents
amino acids. A single amino acid can have more than one codon. The valine codon
can be one of the following: GTT, GTC, GTA, GTG. This is particularly useful
during the translation of mRNA into protein. </span>
Answer:
The answer is D
Explanation:
Because as the energy travels from one animal to the other the energy decreases. For example a gazelle eats the grass right? And then a lion eats the eats the gazelle. The gazelle got energy from the grass it's body already used some so when it's eaten the lion only gets what energy the gazelle has leftover
Answer:
The acidic environment in the stomach stops the action of the amylase enzyme.
The stomach will secrete digestive juice that contain hydrochloric acid and digestive enzyme such as pepsin to digest protein.
The HCL create an acidic environment that will deform the ionic and hydrogen bond of the amylase which cause the enzyme to be denatured.
