A, Kingdom Monera (Archaebacteria) - Numerous members of the remaining kingdoms (Fungi, Plantae, Protista) are not microscopic and hence do not require a microscope to be viewed.
Answer:
Cycads /ˈsaɪkædz/ are seed plants that typically have a stout and woody (ligneous) trunk with a crown of large, hard, stiff, evergreen and (usually) pinnate leaves. The species are dioecious, therefore the individual plants of a species are either male or female. Cycads vary in size from having trunks only a few centimeters to several meters tall. They typically grow very slowly[3] and live very long, with some specimens known to be as much as 1,000 years old.[citation needed] Because of their superficial resemblance, they are sometimes mistaken for palms or ferns, but they are not closely related to either group.
Cycads are gymnosperms (naked seeded), meaning their unfertilized seeds are open to the air to be directly fertilized by pollination, as contrasted with angiosperms, which have enclosed seeds with more complex fertilization arrangements. Cycads have very specialized pollinators, usually a specific species of beetle. Both male and female cycads bear cones (strobili), somewhat similar to conifer cones.
Cycads have been reported to fix nitrogen in association with various cyanobacteria living in the roots (the "coralloid" roots).[4] These photosynthetic bacteria produce a neurotoxin called BMAA that is found in the seeds of cycads. This neurotoxin may enter a human food chain as the cycad seeds may be eaten directly as a source of flour by humans or by wild or feral animals such as bats, and humans may eat these animals. It is hypothesized that this is a source of some neurological diseases in humans.[5][6]
Cycads all over the world are in decline, with four species on the brink of extinction and seven species having fewer than 100 plants left in the wild.[7] The plant has a very long fossil history, with evidence that they existed in greater abundance and in greater diversity before the Jurassic and late Triassic mass extinction events.

Answer:
B) It can remain, circulating in the blood indefinitely, this is not a fate of glucose circulating in the blood of a healthy individual.
Explanation:
Glucose is produced by breaking down carbohydrates, principally in the small intestine, when we eat a meal containing carbohydrates.This glucose enters the bloodstream.When glucose is in excess, the body stores it away in the form of glycogen in a process stimulated by insulin. Glycogen is a large highly branched structure, made from lots of glucose molecules linked together.Glycogen is mainly stored in the liver and muscles, therefore, excess glucose is removed from the blood stream and stored.
Insulin signals to the cell to translocate Glut 4 to the cell membrane, so that large amounts of glucose can be taken into the cell, via the Glut 4 transporters and converted into glycogen and used as a fuel for cellular activities. Furthermore with the help of insulin, converted into fatty acids, circulated to other parts of the body and stored as fat in adipose tissue.

Answer:
B. ...includes methods like metagenomics, which sequence and interpret all the DNA in an environmental sample.
Explanation:
Environmental microbiology is the science in charge of the study of microorganisms, small living things known as microbes. Study organisms that are only visible through a microscope, such as prokaryotic and simple eukaryotic organisms.
Metagenomics is the study of a collection of genetic material from a mixed community of organisms. Metagenomics usually refers to the study of microbial communities. It is generally used when studying microbial communities in which one microorganism cannot be separated from another.
