Answer:
Natural selection
Explanation:
Natural populations have variations. Organisms of a population have various genetic traits. Some of these genetic variations make the organisms better suited to the prevailing environmental conditions. These organisms are more likely to produce more progeny. Over generations, the frequency of the beneficial genetic traits increases in the population due to the higher reproductive success of the organisms with these genetic traits.
This process of differential fitness of organisms of a population where the organisms with adaptive genetic traits have survival and reproductive benefits is called natural selection.
Answer:
Answer is A.
"Lava", "Magma" and "Volcano".
Explanation:
As we should know before now that Volcano occurs when tectonic plates slide against each other.
This rupture on the earth allows hot "lava", and gases to escape from a "magma" vent. All these sum to be a "volcano".
Answer: D.) a suggested answer to a problem
Explanation:
A hypothesis is a supposition, suggested answer or a proposed explanation based on limited evidence which can be use to start an investigation. A hypothesis is more than a guess but less than a established theory and it can be tested through study and experiments.
<u>A hypothesis is part of the scientific method </u>because it is a prediction which can be tested and the results from those experiments may disprove a hypothesis, but can never entirely prove one.
It is not a conclusion because it is an idea which tries to explain an observation. It is not information collected from experiments because hypothesis are formulated before carrying out the experiments and it is not a widely accepted idea because it just proposes a tentative explanation about a phenomenon.
Answer:
True.
Explanation:
Antigen may be defined as the chemical that has the ability to evoke the and immune response and can harm the living organisms. The specific antibody are produced against the immune response.
The antigens has evolved different mechanisms to prevent themselves from them the immune system of the host. The antigenic shift is the most common change that might occur in viruses that helps the antigen to protect itself by changing its genetic material. No anti viral drugs are available for the viruses.
Thus, the answer is true.
July is the warmest summer it has been proven by me and my fellow class mates.
