Answer:

The two point sources of water pollution in the image are coal-burning power plant and factory.

Explanation:

Pollution refers to the release of waste and harmful substances to the environment. Substances which are harmful to the environment are known as pollutants.

Water pollution involves the contamination of water by pollutants making it unfit for human use such as such for drinking or cooking or for other uses.

The source of pollution water bodies have been divided into point and non-point sources of water pollution.

Point sources release pollutants from a single source and are transported directly through media such as a discharge pipe. The main point source of water pollution are factories and sewage treatment plants.

Nonpoint source pollution comes from various sources usually a combination of pollutants from a large area rather than from a specific sourc that can be easily identified such as discharge pipes. Most common is runoff water from city streets or agricultural settlements.

If a corn plant was heterozygous for kernel color and seed shape, what would be the genotype of the plant?

NNADVOKAT [17]

Answer:

The genotype of the plant will be PpSs and the phenotype will be purple colour and smooth shaped.

Explanation:

Considering the description in the question, we know that purple colour is dominant over the yellow colour and smooth shape is dominant over the wrinkled shape.

A homozygous trait can be described as a trait which arises due to the same alleles of a gene. A heterozygous trait arises when both the alleles of a gene are different. In such a case, one allele will be dominant over the other one and the phenotype of the dominant allele will be seen in the plant. As purple colour and smooth shape are dominant traits, hence they will be seen in the heterozygous plant.

Which of the statements does not describe a benefit of genetically modifying organisms for humans?

Mashutka [201]

$\textbf{ \textit{Hello There! I'm here to Help :3}}$

---------------------------------------------------

Answer:

C. bacteria genetically modified to be antibiotic-resistant

Explanation:

Genetically modifying organisms can be either beneficial or harmful for humans. As we can be infected by bacteria, we developed antibiotics to fight those infections, and this saves many lives as it is an efficient medicine. But when a bacteria is genetically modified to be resistant to antibiotics, we can be harmed as we don't have a way to fight the infection and the bacteria will spread (even maybe kill us). Therefore, bacteria that are antibiotic-resistant do not benefit humans, and the correct answer is C. bacteria is genetically modified to be antibiotic resistant.

What are DNA and ran both called

Rama09 [41]

Hi there!

Both DNA and RNA are known as nucleic acids - they are genetic material. The only difference is DNA stays inside the nucleus whereas RNA is transcribed to create proteins. (I believe).

Hope this helps!
