When there is a mutation in a gene that produces an enzyme, it can cause disease. Phenylketonuria<span> or PKU is a rare inherited disorder that causes the build up of phenylalanine. This can lead to brain damage in individuals with this disorder if they don't eat a very protein-- restricted diet. The gene mutation doesn't allow the creation of the </span>enzyme<span>needed to break down Phenylalanine, an amino acid in proteins.

hope this helps

Novay_Z [31]

Answer:

d. Monosomy X is the only viable monosomy known to occur in humans.

Explanation:

Human have 22 pair of homologous chromosomoses and an extra pair of sex chromosomes. While in males the sex chromosomes are X and Y , females have two chromosomes X . Anyway, in normal conditions the total number of chromosomomes that humans have in their cells is 46 (23 pair of chromosomes).

Aneuploidy is a biological condition where an individual have an abnormal number of chromosomes in their cells. In humans for examples, this would be a human having more or less than 46 chromosomes.

The Turner syndrome also called monosomy X is an aneuploidy where one of the X chromosomes is missing in a female. Although under constant supervision, people with Turner syndrome have viable healthy lives. However this is the only monosomy that occur in humans that is compatible with life.

ozzi

Answer:

poliinators and flagellated sperm

Explanation:

Cycads (phylum Cycadophyta) together with Ginkgophyta, Gnetophyta, Pinophyta, Pteridospermales and Cordaitales belong to the gymnosperms (naked seed-producing plants). They are different than angiosperms which produce encased seeds within an ovary.

Cycads (but also Ginkgo) produce swimming sperm that is different than all other groups which produce sperm without swimming flagella.

Also, unlike other groups of gymnosperms, cycads have specialized pollinators, beetls.

<span>D. In a study of the effect of lawn fertilizer on the health of a backyard pond, biologists grow two colonies of duckweed in a large flask to represent pond ecosystems. </span>

The scientific design in which has limitations due to oversimplification is the statement “in a study of the effect of lawn fertilizer on the health of a backyard pond, biologists grow two colonies of duckweed in a large flask to represent pond ecosystems”. Oversimplification is an overview and generalization of a statement to miscomprehension, misperception or even error. It overlaps the true statement.
