Which statement is TRUE?

Biology
1 answer:
Phantasy [73]3 years ago
6 0

Answer:

A

Explanation:

All living organisms ranging from unicellular prokaryotes to multicellular eukaryotes contain genetic material (DNA). This genetic material is usually found on structures called CHROMOSOMES. Although, the chromosomes are contained in the genome of all living organisms, there are differences.

The genetic material of the bacteria (a typical prokaryote) is a single DNA molecule that makes up its single circular chromosomal material, unlike in eukaryotes that contains double-stranded DNA molecules on linear chromosomes. This single circular chromosome of bacteria is found naked in a region of their cell called NUCLEOID, as they do not possess a membrane-bound nucleus that houses it (a unique characteristics of eukaryotes).

The mitochondrial and Chloroplast DNA mentioned in the other options are all components of eukaryotic cells. Bacteria, as a prokaryote does not contain this organnelles. Hence, they are not single replica.

What happens to the average kinetic energy of a substance as its temperature increases
Molodets [167]

Answer:

When the average kinetic energy of the molecules goes up (a rise in temperature), the average speed of the molecules increases. And lower average kinetic energy of the molecules means they have lower speed.

PLEASE HELPP!! match the word with the definition
alexira [117]

Answer:

A. Miosis

B. DNA molecule

C. Body cells

D. phenotype

E. Recessive traits

F. genotype

G. Punnet square

H. nondisjunction

I. mitosis

J. sex cells

Explanation:

In meiosis cell division, a parent cell divides into four daughter cells whereas in mitosis, one cell divides into two daughter cells. If change occur in DNA molecules, mutation occurs. Phenotype refers to physical characteristics of an organism whereas genotype indicates genetic characteristics. Recessive traits only appears when the organisms have same traits or allele. Somatic cells is known as body cells whereas gametes is known as sex cells.

What are frankenfoods? Are Genetically Modefied foods safe?
barxatty [35]

Opponents of GMOs have been unceasing in their campaign to vilify genetically modified foods by describing them as “Frankenfoods,” thus implying they are not natural and are potentially harmful.

“The practice of introducing new DNA and chemicals to seeds or animals (Aqua Advantage has developed a GMO fish) is similar to how Mary Shelly’s Frankenstein created his monster–—through piecing together lots of different organisms,” wrote the Organic Authority on its website—a common allusion in the anti-GMO world. “We all know what happened when the monster turned on Frankenstein, and many critics of genetic engineering have likened the inevitable backlash of GMO technology to the destruction and murderous rampage of Frankenstein’s monster.”

Many anti-GMO articles that warn of the dangers GM crops are often accompanied by an image of a tomato fruit or vegetable with syringes sticking out of them. Very often it is a fruit or vegetable for which there is no current GM equivalent such as a tomato. This depiction is used to reinforce the notion that GM foods are created in laboratories and not by nature and therefore are dangerous to consume.

With the constant barrage of scare-based imagery, it is not surprising that there is widespread public suspicion that GMOs are dangerous to human health. But there is little controversy surrounding GMOs within the scientific community with 88 percent of the members of the American Association for the Advancement of Science believing GMOs are “generally safe.” The safety of GMOs were once again reinforced by the May 2016 report by the U.S. National Academy of Sciences, Engineering and Medicine, which concluded, there was “reasonable evidence that animals were not harmed by eating food derived from genetically engineered crops”, and epidemiological data indicated there was no increase in cancer or other health related problems associated with these crops entering our food supply.

David Zilberman, a professor of agriculture and resource economics at the University of California, Berkley, has noted that Frankenfood was “a terrible word, a stigmatization word, one that’s used to scare people… People are afraid of GMOs for little or no reason. GM is simply a tool. Because it allows us to modify plants with far greater precision and control then before, it will be very valuable.”

The reality is that the vast bulk of the foods we consume whether organic or conventionally grown have had their genetics altered in the field or in a laboratory via a process of selective breeding or advanced biotechnology techniques, and all such foods are safe to eat. The altering of genes in plants is even known to occur naturally as highlighted by the sweet potato.
