Occasionally a new resistant strain of pathogen appears. The new strain may spread rapidly. Explain why

Answers

Answer:

Antibiotics are not effective for new strains and so new resistant pathogens survive and reproduce, which leads to the increasing population of resistant pathogens and spread rapidly.

Bacteria can evolve and adapt themselves quickly as they are able to reproduce at a fast rate. Mutations of bacteria produce new strains that are resistant to certain antibiotics, such as penicillin, and cannot be destroyed by the antibiotic so they spread more rapidly.

A. Changes in climate
B. Number if species at the specific time
C. Composition of Earth's core
D. Age of organisms when they died ​

Answers

Answer: changes in climate

Change in climate information that fossils in samples from Earth's crust reveal about Earth's history. So, the correct option is (A).

What are Fossils?

A fossil is defined as the preserved remains, impression, or trace of a once-living thing from a past geological age, including bones, shells, exoskeletons, fossilized traces of animals or microbes, amber, hair, petrified wood, and DNA. The totality of fossils is known as the fossil record.

There are five types of fossils which are as follows:

Body FossilsMolecular FossilsTrace FossilsCarbon FossilsPseudo fossils

The fossil record shows that the types of living things on Earth changed over time which reveals the Earth's history.

Thus, change in climate information that fossils in samples from Earth's crust reveal about Earth's history. So, the correct option is (A).

Why scientific naming is necessary?

Answers

Answer:

The correct answer would be - to communicate unambiguously globally.

Explanation:

In different locations on the earth or countries, there are thousands of languages present, and each language has a name for the different species or different organisms that leads to confusion and tough to take the record.

Therefore, there is a two-part scientific name system proposed for every species first name for the genus and second part for the species, it is called "binomial nomenclature." It helps and allows to communicate unambiguously about the species of different organisms globally.

Chloroplasts and Mitochondria are two organelles that are largely
responsible for the cycling of carbon through the ecosystems. What are
their functions?

Answers

Function for Mitochondria - Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell's biochemical reactions. Chemical energy produced by the mitochondria is stored in a small molecule called adenosine triphosphate (ATP).

Function for Chloroplast - In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

during glycolysis?
a) Nothing, glycolysis does not affect the glucose molecule
b) The atoms are converted into other molecules in a series of chemical reactions
c) The atoms are transformed into energy
d) All atoms are transformed into other atoms in a series of chemical reactions

Answers

Answer:

b.

Explanation:

the atoms are converted into other molecules (pyruvate) in a series of chemical reactions

Glucose consists of carbon, oxygen and hydrogen atoms. The thing that happens to these atoms  during glycolysi is that The atoms are transformed into energy

Glucose is a type of simple sugar that has six carbon atoms and during glycolysis, is broken down easily because it is a monosaccharide

Glycolysis is the process of breaking down and converting glucose into CH₃COCOOH.

Therefore, what happens to carbon, oxygen and hydrogen atoms during glycolysis is that they are transformed to energy

How may mRNA be modified before it leaves the nucleus?

Answers

Answer:

The pre-mRNA molecules undergo three main modifications. These modifications are 5' capping 3' polyadenylation and RNA splicing which occur in the nucleus before RNA is translated.

Explanation:

mRNA compares to the hereditary succession of quality, and is perused by a ribosome during the time spent combining a protein.

How mRNA can be modified?

it should go through extra handling before it leaves the core. This might incorporate joining, altering, and polyadenylation. These cycles adjust the mRNA in different ways. Such alterations permit a solitary quality to be utilized to make more than one protein. Exons are segments of mRNA which become "communicated" or converted into a protein. They are the coding bits of a mRNA atom.

Cross two heterozygous black mice and tell the possible phenotypes and
genotypes in their offspring.

Answers

Answer:

Phenotype: 3 black mice: 1 brown mice

Genotype: 1 BB: 2Bb: 1bb

Explanation:

This question involves a single gene coding for fur color in mice. The allele for black color (B) is dominant over the allele for brown mice (b). This means that a mouse that is heterozygous will be black.

If two heterozygous black parents are crossed i.e Bb × Bb, the gametes produced by each parent are: B and b. Using these gametes in a punnet square (see attached image), the following offsprings will be produced:

BB, Bb, Bb, and bb

- The phenotypes of this cross is  3 black mice: 1 brown mice

- The genotypes of the cross is 1 BB: 2Bb: 1bb
