Answer:
A: They produce a real image.
Explanation:
The images formed on the retina of the eye for a normal visibility must always be real.
Only a real image can be physically projected on any physical object whereas the virtual images are visible due to reflections.
- The nearsightedness is corrected with the help of a concave lens since it is the condition of the eye lens remaining thick and curved to converge the rays entering the eyes after a shorter distance which results in their image formation even before the retinal surface so to initially diverge them a bit so that they converge on the retinal surface and form the image there we use concave lens. Vice-versa of the above justification in the case of farsightedness.
Bacteria and Binary Fission-
Many single-celled organisms rely on binary fission to reproduce themselves. All bacteria reproduce by binary fission.
Budding and Hydras-
Hydras are a type of freshwater cnidarian related to jellyfish, sea anemones and corals. Hydras reproduce asexually by developing small, genetically identical polyps that protrude from the parent. These polyps break off from the parent to form a new organism in a process called "budding."
Parthenogenesis and Copperheads- Though most of the organisms that use asexual reproduction are invertebrates, several species of vertebrate animals do make use of it. Some, like copperhead snakes, can reproduce asexually as an alternative to their typical sexual reproduction. Through a process called parthenogenesis -- literally "virgin birth" -- copperhead females can give birth to live young without having been inseminated by a male, even when males are available, according to National Geographic. In this form of parthenogenesis, the polar body, or a cell produced alongside the female's egg, acts as a sperm cell and essentially "fertilizes" the egg. Parthenogenesis has been observed in several species of reptiles, birds and sharks, and is especially common in insects.
Answer:
b. (4677)
Explanation:
You can apply the same equation we use to calculate the compound interest but with phones.
Look:
M = C.(1+i)^n
M = the total amount after 5 years
C = the firts amout of phones (285)
i = how much this number gets bigger (75%)
n = the number of periods (5 years)
So...
M = 285 . (1 + 0,75)^5
M = 285 . 1,75^5
M = 285 . 16.4
M = 4677
