Microorganisms Feast on Sewage, Creating More Problems

That algae and bacteria switch into overdrive, growing to the point where most of the dissolved oxygen that is naturally found in water is used up. That makes it tough for other organisms in the water ecosystem to live because they are basically being strangled.

Answer:

It is a known fact which has been proven by researchers in different published articles on how sewage has greatly affected lives in aquatic environment. Every living organisms found in aquatic environment survives best when the pH of the water is neutral or a bit above slightly, sewage contributes to increase in acidity of aquatic environment, hence; reduces lives in such environment.

How does a mutation in the DNA affect the way proteins are made?

Vikentia [17]

Explanation:

B.) A mutation in the DNA results in a change in the mRNA and, ultimately, to a different protein structure.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. To produce daughter cells during cell division, the chromosomes (total number of chromosomes (2n)) are copied before the cell splits into two daughter cells.

During the process of cell division, spontaneous changes within the genome can arise. These mutations are errors occur when copies of the DNA within the cell are made; mutations may range from small changes called single nucleotide polymorphisms, to large scale deletions, and additions which span multiple genes. There are two types:

somatic: these only occur within certain cells, and arise from environmental factors such as UV light
hereditary: occur within germ cells of the parent and later the fertilized egg which forms a zygote; these are present within all cells of the new organism.

Nucleic acids are comprised of smaller units called nucleotides and function as storage for the body’s genetic information. These monomers include ribonucleic acid (RNA) or deoxyribonucleic acid (DNA). They exist solely to encode and carry out protein synthesis.

The message on DNA, called genes is copied by RNA polymerase, to form mRNA complementary sequence to that of the DNA strand in transcription. These are then translated into proteins in ribosomes. Mutations in DNA sequences affect the corresponding mRNA and thus the protein encoded.

They are maintained within cells, as they form new traits called alleles, which may confer adaptations that increase the fitness of a species, along with ensuring survival by conferring a protective advantage.

e.g. sickle cell anemia, a disease caused by a mutation, confers protection against the disease malaria.

Guys please help I'm stuck (science).

erastovalidia [21]

Scientific law is the detailed explanation of observed phenomena. It is not explaning what is the cause of the phenomena. So , we can say that explanation of phenomena is the scientific theory. They are testable .

example : Theory of electricity, chemistry

In everyday language a theory means a guess or speculation. Everyday Theory introduces students to theory and how it applies to everyday life.

Structure that carries the sperm cells

iris [78.8K]

The vas deferens is a long, muscular tube that travels from the epididymis into the pelvic cavity, to just behind the bladder. The vas deferenstransports mature sperm to the urethra in preparation for ejaculation. Hope this is correct!

USPshnik [31]

It is 70-80 action potentials per minute. The rate of phase 4 depolarization in the SA node sets the Heart rate, The SA node serves as the Pacemaker It has the greatest automaticity And ability to spontaneously generate an action potential.
