Answers

Answer 1

Answer: In everylaboratory that uses it for experimentation, it is very important that users ofthe laboratory must be oriented about their safety and the code of thelaboratory. For one, it will allow you to be alert at all times when using forexample, an unknown chemical. Two, it will help you understand how to use theapparatus present inside the laboratory. Three it will protect you againstunforeseen events. So before viewing prepared slides under a microscope, thestudents should review the safety rules if there are accidents such as; cuttingyourself from the prepared slide, informing the professor if the prepared slideis broken, asking the laboratory-in-charge for assistance on how to use themicroscope. That way, the flow of the class will run smoothly.

Charles Darwin did poorly in school as a young boy. How did his poor performance belie his genius?

Answers

Charles Darwin always had a taste for natural history as a kid, as far back as eight, in spite of how he performed in school. When he was a young adult, he got an apprentice ship as a doctor from his father who was also a doctor. This gave him experience with the anatomy of the human body. When being a doctor started to bore him, he learned taxidermy, exposing him to the anatomy of wild animals. Later he joined the Plinian Society which was a student natural history group that often debated and questioned the current topics and views of the subject in that time. Not too mention the many natural historians and evolutionists who also inspired him, one of which was his own grandfather,that gave him the support he needed. I guess that even though his normal school curriculum did not interest him, his self determination was enough to keep him grounded to his interests, proving that sometimes a great education doesn't always make you a genius. (idk :) Charles Darwin was smart in his own ways.

Referred to as a giant molecule

Answers

Giant covalent structures contain a lot of non-metal atoms, each joined to adjacent atoms by covalent bonds. The atoms are usually arranged into giant regular lattices - extremely strong structures because of the many bonds involved. The graphic shows the molecular structure of diamond and graphite: two allotropes of carbon, and of silica (silicon dioxide).

Chromosomes, which contain DNA, have several functions. All BUT ONE of these statements is a function of chromosomes. A) Chromosomes determine the traits of an organism. B) Chromosomes provide instructions to make proteins. C) Chromosomes determine the gender of an individual. D) Chromosomes help an organism produce usable energy

Answers

Answer: The correct option is D) Chromosomes help an organism produce usable energy.

Chromosomes are the thread like structures made from the packaging of the nucleic acid DNA. They are localized in the nucleus of most living organisms.

Chromosomes do not help an organism to produce usable energy.

Rather they provide instructions to make proteins in the form of genes ( segment of DNA providing information for protein). Proteins are therefore used in determining traits of an organism. Chromosomes are also used in determining gender of an individual. For instance, the presence of Y chromosome determine the male sex and XX determines the female sex amongst human.

Thus, option D) is not the right function of chromosomes.

The correct answer is

D) Chromosomes help an organism produce usable energy

Chromosomes do not, in any way, help and organism produce usable energy.
