One example of how applied science has had a direct effect on daily life is the presence of vaccines. Vaccines to prevent diseases such polio, measles, tetanus, and even the influenza affect daily life by contributing to individual and societal health.
Answer:
64
Explanation:
Since the population is in Hardy-Weinberg equilibrium and the equilibrium is defined by the equation
p² + 2pq + q²
where the frequency of the homozygous dominant allele F ( feathers on the leg ) = p²,
F of homozygous ( featherless legs) = q²
F of heterogyous ( carrier of featherless allele) = 2pq
F (q²) = 128/200 = 0.64
q = √0.64 = 0.8
and p + q = 1
p = 1 - 0.8 = 0.2
2pq = 2 × 0.2 × 0.8 = 0.32
number of chickens that are heterozgous for the feathered leg allele = 0.32 × 200 = 64
Answer:
1 - natural selection
2 - uniformitarianism
3- inheritance of acquired characteristics
4 - catastrophism
Explanation:
1. Natural selection refers to the evolution of organism or changes in the characterstics of organism depending on the environmental conditions. Hence, the lizard moved on fantasy island evolved with larger head and stronger bites as per the environmental condition.
2. The concept of Uniformitarianism states that the natural geological processes happening in present have already occured in past with same intesity and rate. Hence, geologist uses the phrase "The present is the key to the past" for formation of mountain, rock formation and water movements.
3. Inheritance of acquired characteristics are the characteristic acquird by the ancestors and transmitted that gradually acquired characteristic to their progeny. Hence, the rats acquire the charactieristics and transfered it to the next generations.
4. Catastrophism means the regular occurrence of meteorological and geological disturbances to explain the existence the fossil record. Hence, teh mass exticiton due to asteroid impact is an example of Catastrophism.
So, the correct options in sequential order is natural selection, uniformitarianism, inheritance of acquired characteristics, and catastrophism.
Answer Options:
a. glycogen + fructose = maltose
b. galactose + glucose = lactose
c. glucose + sucrose = fructose
d. maltose + lactose = cellulose
Answer:
b. galactose + glucose = lactose
Explanation:
Monosaccharides are single units. Disaccharides are molecules of two monosaccharides joined together.
Examples of monosaccharides include glucose, fructose, and galactose.
Examples of disaccharides include lactose, maltose, and sucrose.
The only example that shows this is b.
Answer: Option D.
Protist.
Explanation:
Amoeba and paramecia belong to kingdom protist.
This kingdom comprises of Eukaryotic organisms that are multicellular or unicellular. They have nucleus and membrane bound organelles which are use in performing life processes. Some protist are free living such as algae while some are heterotrophic and some are parasitic. They have Mitochondria and the live in moist or aquatic environment. They have cilia or flagella for loccomotion.
