Answer: (A) The conclusion is valid because the independent and dependent variables in experiment were controlled.
Explanation: There are some basics requirements in order for an experiment to be valid: hypothesis, monitoring, independent and dependent variables and constants.
Answer:
Almost nothing. We’d have plenty time to pack our bags and leave.
Explanation:
The random-walk process, radiative diffusion, causes the photon to take millions years to reach the surface of the Sun. So if fusion in the core of the Sun suddenly stopped, the surface would continue to shine for millions of years, and therefore, the luminosity would not decrease abruptly.
Answer:
D
Explanation:
D) Volume mass and density
volume mass and density do not change because when the necklace is melted down it doesn't change the amount or density of the necklace.
Answer:
Protein benefit animals because they need this to form new skin cells. They also use protein to grow hair, build muscle tissue etc. Protein also helps the animals to create chemicals like hormones and enzymes that are needed for their normal function.
Explanation:
The probability of the offspring of a heterozygous father and homzygous mother having five fingers is 50%.
<h3>How to calculate genotype of a cross?</h3>
According to this question, a gene coding for the number of fingers in humans is involved. The allele for six fingers (F) is the dominant trait while the allele for five fingers (f) is the recessive trait.
If a cross between a heterozygous father that posseses a genotype of Ff and a homzygous mother that posseses a genotype of ff, the following offsprings will be produced:
This shows that the probability of the offspring of a heterozygous father and homzygous mother having five fingers is ½ (50%).
