A theory is a unifying explanation for a broad range of observations. Science has come up with the scientific method to answer questions through observation. When something has been repeatedly experimented and results are yielded from them scientists cannot conclude answers to their problems just yet.
A controlled experiment needs to be tested multiple times until it yields an average solution that would generally be coming from different testers. Basically, a theory is something that has been repeatedly confirmed through some form of experimentation and observation.
Answer:
A) all the genes that occur in the population.
Explanation:
The gene pool is defined as the set of all genes in population. The larger the genetic pool in population is, the grater genetic diversity is so the population can survive intense process of selection. On the other hand, low genetic diversity can cause reduced biological fitness and the chance of extinction is increased.
Answer:
Begins with/Ends with: One diploid cell, four haploid cells
Occurs in: Humans, animals, plants
Results in: Sexual Reproduction, Seeds
Type of Reproduction: #1 (too long to type :)
Function: Biological reproduction, generation of the species
Hope this helps!
Answer:
B
Explanation:
Natural selection works by selecting organisms that have unfavorable traits and killing them. However, if all the hydras are identical(from asexual reproduction), then there is no single organism that has a favorable trait over another.
4 mps increase in 10 seconds = 2 mps increase in 5 seconds = .4meters/2sec
