How do different densities affect small organism?
small organisms have more oxgyen than big organisms
Why does natural selection only work on phenotypes?
Natural selection is based on the environment and on the traits of organisms. Organisms with more suitable traits are more likely to survive until reproductive age, while organisms with less suitable traits are more likely to die before they can reproduce. Most of these traits are genetic traits. The phenotype is the set of all genetic traits. Natural selection is not determined by genotypes, because genotypes are merely an organism's genetic makeup. Only the dominant or somewhat dominant alleles in the genotype will also appear in the phenotype. However, genotypes still contribute to natural selection indirectly in that two alleles in two parents' genotypes which had not appeared in their phenotypes could be inherited such that they are in the phenotype of the offspring.
How does the deaths of organisms in the water lead to the death of more organisms?
If you mean organisms that live in water, then that will affect the ecosystem because some organisms won't have the dead organisms that they used to feed on, which will cause their death. On the other hand, if you mean the death of organisms that live on land in water, then that will affect the water, and will probably make it contaminated, which will cause the death of the organisms that drink the contaminated water.
Is DNA stored in cytoplasm or chromosome?
chromosome, pay attention more in class
Do more complex organisms always have more chromosome than simpler organisms do?
Yes
Do more-complex organisms always have more chromosome than simpler organisms do?
Yes
Can organisms with fewer chromosomes reproduce more easily than organism with more number of chromosomes?
can organisms with fewer no of chromosome reproduce more easily than organim with more
Name two factors that determine the phenotype of a trait?
genes
Traits controlled by recessive alleles on the x chromosome are more common in males than in females explain why?
Males only have one X chromosome, so even if the gene on that chromosome is recessive there is no other gene that could dominate it. Females have two X chromosomes, so if the gene on that chromosome is recessive there is still a chance that the gene on the other chromosome could be dominate and override it.
Does Hemophilia affect men more than woman?
Yes. In fact hemphilia only affect men. The condition is tied to the male chromosome.
How do different densities affect small organism?
small organisms have more oxgyen than big organisms
What is euckaryotic?
Eukaryotic organismsare those organisms that have a well defined nuclear region and a nuclear membrane. they have more than one chromosome and the vacuols are present.
What are alleles that have an effect on an organisms phenotype?
The presence of more than two alleles for a trait is known as probility. There might be one which is dormant and the others which are recessive.

Why is phenotype more important than genotype?
Phenotype is the displayed characteristics of the organism, as opposed to the genotype, which is the gene sequence of the organism. Phenotype is important because it includes everything that the organism can do. Whether a plant is pink or red, an example of phenotype, can influence whether or not a bee will be attracted and pollenate it. The presence of cystic fibrosis, a debilitating disorder in humans, is caused by genotype but expressed through phenotype, and can be the difference between death at twenty or a long life to eighty.
