Answers
Answer:
The correct answer is - flatworms and roundworms.
Explanation:
Helminths are the group of free living and some are parastic organisms present in aquatic, terrestrial environment or in animals or plants respectively. parasitic helminths are the group of worms or organisms that lives inside the GI tract or other parts of the body of host and makes them weak. The two major groups of parasitic helminths are -

Thus, the correct answer is - flatworms and roundworms.
Zoologist: Horseflies are attracted to horizontally polarized light, which reflects off large, dark animals that they bite. This may explain why zebras evolved vertical stripes—the stripes cancel the horizontal polarization of light and thus make zebras less attractive to horseflies.
In order to assess the plausibility of the zoologist's hypothesis, it would be most helpful to know whether
A. any insects other than horseflies are attracted to horizontally polarized light.
B. the vertical stripes on zebras make it easier for any insects other than horseflies to see them.
C. animals that horseflies commonly bite have evolved other means of reducing the impact an frequency of those bites.
D. any biting insects other than horseflies are strongly attracted to zebras.
E. zebras' vertical stripes provide camouflage protection against certain large predators potentially very dangerous to zebras.
Answers
Answer:
D. any biting insects other than horseflies are strongly attracted to zebras.
Explanation:
In order to assess the plausibility of the zoologist's hypothesis, it would be most helpful to know whether if any other insects other than the horseflies are strongly attracted to the Zebra. If other insects are attracted to the zebra, we can then try to research and see if these other insects also show tendencies to be attracted to horizontally polarized light before we can conclude on this hypothesis. The hypotheses will hold more strongly if the same phenomenon applies to other biting insects attracted to the Zebra.

OThe use of fossil fuels
Answers
Hi there! :)
Answer:
Glaciers.
Explanation:
Forest fires, Volcanoes and the use of fossil fuels all are sites of combustion. Carbon dioxide, or [tex]CO_{2}[/tex] is a byproduct of this reaction, which makes them sources of this gas.
On the other hand, glaciers are large, frozen reservoirs of water [tex](H_{2}O)[/tex] , which makes them not sources of carbon dioxide.

Answers
Answer:
allele
Explanation:
An allele can be defined as a variant of a gene localized at the same locus or chromosome position. These gene variants may encode the same protein (when different alleles encode the same protein sequence) or different protein variants (when nucleotidic differences encode distinct protein sequences). It is important to note that the diploid organisms (like humans) have two alleles for each gene, which are localized on homologous chromosomes.
A version of a gene is called an allele. Genes are sections of DNA that hold the instructions needed to make certain proteins or useful RNA molecules. Hence the correct option is A.
Alleles are distinct versions or variants of a gene that can cause changes in the trait or feature the gene controls.
Alleles are found at specific locations on chromosomes known as loci. Each gene is present in two copies in humans, one from each parent.
As a result, a person might be heterozygous (having two copies of the same allele for a given gene) or homozygous (having two copies of two distinct alleles).

to be able to grow at any angle
Answers
Answer:
If plants could grow at any angle, resources could be better used, less labor would be spent, and crop production would increase.
Explanation:
By growing at different angles, crops could be generated in different locations that would not normally be beneficial or feasible for plant growth.
For this reason, land use would be higher for farmers as harvests would increase by making better use of the land and generating ideas to make better use of resources.
They could be better used, for example, a scale cultivation on a sloping terrain, no time would have to be spent flattening the ground and only the crops would have to be cared for.

What is a hypothesis?
Repeated experimentation and observation have been used to devise scientific theories. These theories have been further referred to by peer reviews before they have been generally accepted by the scientific community.
Science involves methods and data that make sense of the world. The methods of principles are internally-consistent and well described. The progression from a hypothesis to a theory can only be through testable, scientific laws. There are only a few scientific facts that are natural laws as well but there are many hypotheses that can be tested to generate a theory.
Therefore, the correct options are D and E.

Answer:
The correct answer is : translation.
Explanation:
Translation is the second essential step of the central dogma or the protein synthesis process that is takes place in the ribosomes of the cell, Ribosome reads decode the codon, a sequence of 3 sequence. tRNA comes with the anticodon to the codons that are present on ribosome in order to bind the amino acids to it.
The amino acid that was brought by the tRNA is detaches itself as it bind to the polypeptide chain forming on ribosome to create polypeptide chain, this process repeats itself up-to the stop codon.
Thus, the correct answer is : translation.

What is the controversy behind banning oxo-biodegradables?
Answers
Answer:
Oxo-biodegradables do not meet international biodegradation requirements, which has caused the authorities to prohibit their use, contrary to their formulators who defend their benefits in the environment.
Explanation:
Oxo-biodegradables are a type of plastic that can be broken up into tiny pieces, but that is not biodegraded by the action of nature. In this case, this type of plastic does not meet international biodegradation requirements, in addition, it can cause pollution, as its mini particles can affect rivers, soils, crops, in addition to being dispersed in the air and being eaten by animals.
The great controversy is that the creators of this type of plastic defend their benefit in the environment, however the authorities, considering the polluting potential of oxo-biodegradables, prohibited its use.

Genetic engineering, also known as genetic manipulation, is the use of recombinant DNA to change the genetic makeup of organisms. In the creation of a recombinant DNA, which is usually a plasmid + desired gene, the following processes are employed:1. The target or desired gene is initially cut out using enzymes called restriction enzymes.
2. The plasmid (extrachromosomal DNA) from a bacterium is then cut open.
3. Ligase enzyme is used to bond the target gene or gene of interest with the plasmid.
4. After bonding, the plasmid is inserted into a bacterium to multiply.
