Answer:

In a population, a specific gene has two alleles, 'A' and 'a.' Individuals with

genotype 'aa' die in early childhood. Individuals with genotype 'Aa' have a

higher rate of surviving and reproducing than individuals with genotype 'AA.'

This phenomenon is called survival of the fittest, Darwins law which entails the fittest organisms survives while the ones that could not would go into extinction

Answer: The phenomenon is called heterozygote advantage

Explanation: Heterozygote advantage is a phenomenon whereby a single copy of a recessive allele doesn't result in a disease in a heterozygous individual rather offers an advantage to the carrier (the heterozygous individual). For example, the sickle cell allele does not cause sickle cell disease in the carrier rather confers resistance to malaria in heterozygous individuals, but causes a deadly disease (sickle cell disease) in homozygous individuals.

In science why is it important to have more than one piece of evidence to support your claim?
My name is Ann [436]

Answer:

It is important to have more than one piece of evidence to make sure that the evidence is actually evidence. Or in other words, that the evidence is proven true. With only one piece of evidence, you can't be fully sure if calculations were correct, if the source was trustworthy, etc.

Multiple evidence is kinda like double checking math problems. If you don't do it, you can't be 100% certain the answer is correct.

Define los tipos de proteínas que conforman la membrana
tensa zangetsu [6.8K]

Membrane proteins can be classified into two broad categories—integral (intrinsic) and peripheral (extrinsic)—based on the nature of the membrane-protein interactions (see Figure 3-32). Most biomembranes contain both types of membrane proteins.

Translate:

Las proteínas de membrana se pueden clasificar en dos categorías amplias: integrales (intrínsecas) y periféricas (extrínsecas), según la naturaleza de las interacciones membrana-proteína (véase la figura 3-32). La mayoría de las biomembranas contienen ambos tipos de proteínas de membrana.
