Answer:
• potential for a species to increase in number
• the heritable genetic variation/ which results from mutation in dna
• the size of a population increases
• competiton for resources that are limited in that specific environment.
Explanation:
these are all factors that would affect natural selection although there are many more.
A change in temperature is a sign that a chemical reaction has occurred. This occurs in an endothermic reaction. An endothermic process is any process which requires or absorbs energy from its surroundings, usually in the form of heat. It may be a chemical process, such as dissolving ammonium nitrate in water, or simply the melting of ice cubes.
Hopefully im not too late :/
Answer:
Amino Acids
Explanation:
What Are Proteins Made Of? The building blocks of proteins are amino acids, which are small organic molecules that consist of an alpha (central) carbon atom linked to an amino group, a carboxyl group, a hydrogen atom, and a variable component called a side chain.
Answer:
Answer B
Explanation:
By definition mixtures are combinations of substances physically prepared and physically separated. Mixtures are classified as 'homogeneous mixtures' and 'heterogeneous mixtures'. For homogeneous mixtures all components are dissolved, with solute evenly distributed throughout the solution and assumes state of solvent. 'Heterogeneous mixtures' have inconsistent properties throughout and solute concentration is not consistent throughout the mixture.
Answer:
The volume is 50, 74 liters
Explanation:
We use the formula PV = nRT. The temperature in Kelvin is = 273+ 20 =293K
PV=nRT ---> V = (nRT) / P
V= (2.0 mol x 0,082 l atm /K mol x 293 K) / 0,947 atm
V=50,74128828 l
