Answer:
Pentanol, glucose and fatty acid.
Explanation:
Pentanol, glucose and fatty acid are the three molecules which are present in the given model number 1. In the model, there are three different molecular diagrams for each molecule. The first one is ball and stick model, the second one is Lewis structure and the third one is line drawing method. All diagrams for a same molecule is totally different from another.
Answer:
Option-E
Explanation:
The phospholipid bilayer is the layer which forms the outer membrane of the cell.
The phospholipid layer is amphipathic as it contains both the hydrophilic and hydrophobic portions.
The phospholipid is composed of the glycerol attached to phosphate groups which form head or hydrophilic region and the 3 fatty acid tails which form the hydrophobic portion.
The head or hydrophilic portion is arranged in the layer facing the outer external portions and the inside of the cytoplasm as the lipid layer exist in the bilayer.
Thus, Option-E is correct.
Answer:
c. the cost to growth of allocating resources to defense
d. consistent fitness benefits of high allocations to defense
Explanation:
In order to ensure survival by escape of grazing and browsing by herbivores (and insects) plant usually adopt different defence mechanisms.This forms the basis for the optimum defence hypothesis .
The basic idea of the hypothesis is that the type of defence that an organism e.g plant will adopt against an herbivore depends on its fitness, and since this involve expenditure of energy it will be expensive for the organism to afford and maintain.
Answer:
Principles of Geology
Explanation:
J. Henslow gifted Darwin the first volume of Principles of Geology, written by Charles Lyell. The book explains about the old age of the earth. Accordingly, the slow rate of several geological processes suggests that the earth is very old.
Darwin read the book as the ship was crossing the Atlantic and learned about geological processes occurring over the millions of years. For example, he learned that the earth's surface was not formed by some catastrophic event.
In his book, Lyell explained the slow and gradual geological processes like erosion gave rise to the vast landscapes present on the earth's surface.
Darwin compared the time taken by geological processes to form the earth's surface and reasoned if these millions of years were enough to support the evolution of species.
