There could be an earthquake.
To focus a magnifier using the high-energy lens you haveto use the main focus adjustment knob however take care as a result of if youcrank down too hard, you'll be able to harm the magnifier and therefore the slide.
- Fine Adjustment Knob - This knob is within the coarse adjustment knob and is employed to bring the specimen into sharp focus underneath low power and is employed for all focusing once using high power lenses.
You don't wish to wreck the slide. therefore you ought to forever look on the aspect of the magnifier therefore you do not break it and use fin adjustment knob only.
Hope it helps!
Answer: B. Protein production in the organism would stop.
Explanation: Ribosomes are organelles involved with synthesis of proteins. There are about 10 million ribosomes in a single cell. Therefore, absence of ribosomes would result lack of protein production by the cells or ER.
Answer: B) chemolithotrophs
Explanation: chemolithotroph are organisms that is able to use inorganic reduced compounds as a source of energy. the generation of energy (ATP) and the generation of reducing power (NADH) is the primary goal in chemolithotrophy.
Answer:
(F) 0.84
Explanation:
In this population of cats, there are two possible phenotype related to the tail length, long tail and short tail. According with the information given, we have the following distribution of phenotypes and genotypes in the population:
- TT -> long tail (180)
- Tt -> long tail (240)
- tt -> short tail (80)
The frequency of cats with long tail in the population can be calculated as the fraction of the cats that have the phenotype "long tail" in the population
<em>Fraction of long tail phenotype</em>=(TT individuals + Tt individual)/(Total population)=(180+240)/(180+240+80)=420/500=0.84
So, the fraction of cats with long tail in the population is 0.84
