Answer:

CO2 is creating, ph levels to decreases causing it to become acidic

Explanation:

this is because of us putting more co2 in the air causing great change in ph levels. :(

Answer:

Option B

Explanation:

Using the process of elimination, we will find this answer.

It's not option A because electrical energy involves electricity and has nothing to do with motion/position, although you can build machines fueled on electrical energy to create motion or position. (Hence; vehicles)

It is option B because potential energy is energy the object has when it's at rest, which means when the object remains in the same position it has potential energy.

It's not option C because thermal energy involves heat which you could use heat energy and convert it into electrical and then build a machine that is fueled on electrical energy that creates motion or position. (Hence; boats)

It's not option D because Kinetic energy is purely energy when a object is in motion, has nothing to do with a position of a object. As long as the object is moving it has kinetic energy.

Your answer is option B or "potential energy."

Given what we know, we can confirm that the statement being made is in fact true, Fossils can include traces and imprints of plants and animals as well as their remains.

Fossils are the preserved remains of ancient biological creatures. These fossils are not specific to one type of organism. Instead, fossils often contain many organisms at once. Plants, animals, fungi, bacteria, and single-celled living things are all examples of what we may find within fossils.

Therefore, we can confirm that the statement being made is in fact true, Fossils can include traces and imprints of plants and animals as well as their remains.

Explanation:

There's nothing to get amazed to find all the four types of blood groups in the progeny, provided the parental genotypes are AO and BO.

The four types of blood groups included A, B, AB and O.

Had the parental genotypes been AO and BO, the progeny would include all the four blood groups A with genotype AO, B with genotype BO, AB with genotype AB and O with genotype OO.

It happens only in this case and not in any other as the alleles A and B are co dominant to each other and completely dominant over the allele O.

These antibiotics include penicillin and its derivatives and work by inhibiting the production of the bacterial enzymes

These antibiotics include penicillin and its derivatives and work by inhibiting the production of the bacterial enzymes.

The Penicillium mold is the source of penicillin, one of the first and still-commonly-used antibiotics. The numerous mold species that produce different types of penicillin ; the naturally occurring penicillins (those produced during the fermentation process of mold) and the semi-synthetic penicillins are two categories into which penicillium can be categorized.

All penicillins function in the same way, which is to inhibit the bacterial enzymes necessary for the creation of cell walls in replicating microorganisms and to activate other enzymes that demolish the microorganism's protective wall. They are therefore only effective against microbes that are actively forming cell walls and multiplying, and they are likewise safe for use on human cells.

They find a sudden disappearance of many fossil species.

Explanation:

A mass extinction is usually defined as a loss of about three quarters of all species in existence across the entire Earth over a “short” geological period of time. Given the vast amount of time since life first evolved on the planet, “short” is defined as anything less than 2.8 million years.

The secretion of gastric juice, strengthening of contractions of the lower esophageal sphincter, increased motility of the stomach and relaxation of the pyloric sphincter are stimulated by gastrin. It is a hormone.

A hormone is a chemical messenger produced and secreted by the body tissues in order to play specific roles.

Gastrin is a protein (peptidic) hormone associated with the secretion of gastric acid in the digestive system.

Echo sounding

Explanation:

Echo sounding is the key method scientists use to map the seafloor today. The technique, first used by German scientists in the early 20th century, uses sound waves bounced off the ocean bottom.

Based on the error rate of 1 in 10000 nucleotides, the number of point mutations is 1000 mutations.

DNA repair is the method where errors which occur during DNA replication are corrected.

During DNA replication, the error rate is approximately 1 error for every 10,000 nucleotides copied.

This rate is reduced to only 1 error for every 1 billion nucleotides by DNA repair proteins.

Since the DNA repair proteins of the organism are faulty, the error rate is 1 in 10000.

Number of nucleotides copied = 2 × 50,000,000 = 100,000,00

Number of errors = 100,000,00/10,000 = 1000 point mutations

Therefore, the number of point mutations is 1000 mutations.
