1)magnification goes by 10x (read 10 times), 100x,1000x and some goes 10,000x
2)Always focus first using lowest power possible first, switch to medium power (100x) after it's focused on low power(10x), on 100x, use the small knob to focus it more. DO NOT touch the bigger nob when in medium or high power. Switch to high power (100x) when it is focused on medium power, again focus again using the small knob on high power.
3) So it doesn't gather dust and fog up the lense? that one should be self explanatory
The number who reach sixty years of age will be higher because first of all, there will more and better health services available and the life expectancy of people is expected to rise.
Note: Question lack some information i have added full question with answer as picture. see attachment.
Answer:
d. In the first stage, macro-molecules are converted to monomers, and a small amount of ATP is produced.
e. In the second stage, monomers are broken down, and a small amount of ATP is produced.
c. In the third stage, fuel molecules are completely oxidized to CO2, and no ATP is produced.
Explanation:
When we take food a process starts which is called as cellular respiration. Through this process the food energy is converted into cellular energy which will further used by body. During all this process oxygen and glucose are converted into water and carbon dioxide and energy in this process is converted into ATP.
Answer:
tentatively group it with birds and speculate that the trait shared only with bats is a derived rather than an ancestral trait with bats.
Explanation:
The scientist after his observation should tentatively classify this organism with birds and the the second end of calculating the other morphological traits which makes it possess the likely bat traits to be ancestral.
According to scientists, most widely used modern systematic practice
depends upon the assumption that a change from character in one species
to character occurs once and once only in the evolutionary process and that this process is irreversible so that it never returns.
In this scheme, there are no independently derived parallel evolutionary changes,
nor convergences from a variety of states to a single one. Therefore, when two organisms share a
character state different from other species, it is because they are more closely related to each other through a recent common ancestor than they are to other species.
Also using the parsimony principle, a scheme of common ancestry for all the species is derived that uses all the characters that have been observed.
A vertebrate-animal embryo gives rise to the centrum. The centrum is a bone that is part of the vertebral column. It is the hollow space within the vertebra that protects and contains the spinal cord. Within this hollow area are several nerves that send impulses to the brain enabling the organism to function and be at its homeostasis.
