A car travels 300 km in 6 hours. What's the average speed of the car? O 50 km/h O 65 km/h O 45 km/h O 75 km/h
Answer:
50 km/h
Explanation:
The average speed of the car is essentially the same thing as the unit rate.
Here a car goes 300 km for every 6 hours. To find the unit rate, we must find how many kilometers it goes per hour.
To do so, we can divide 300 by 6 to get a total of 50km/h.

Why do land breezes occur at night?
Answer:
Land breezes usually occur at night because during the day the sun will heat land surfaces, but only to a depth of a few inches.
Explanation:
As the temperature of the land surfaces cool, the warm air rises and creates a small area of high pressure near the land surface.

the Nucleus
Explanation:
Known as the cell's “command center,” the nucleus is a large organelle that stores the cell's DNA (deoxyribonucleic acid). The nucleus controls all of the cell's activities, such as growth and metabolism, using the DNA's genetic information.
Energy-rich molecules that organisms use to carry out daily activities are:.
For a heterozygote, production of sufficient quantities of the functional protein by the ______ allele compensates for the production of a non-functional protein by the ______ allele.
For a heterozygote, the production of the protein by the DOMINANT allele compensates for the production of a non-functional protein by the RECESSIVE allele. It is classical genetics.
Alleles and dominanceAn allele is a gene variant, diploid individuals inherit two different alleles for a given gene locus.
A homo-zygous individual has the same alleles, whereas a heterozygous individual has two different alleles for a given gene locus.
Dominance occurs when the dominant allele completely masks the expression of the recessive allele.

in water
Producers produce glucose in the chloroplast
What are Chloroplasts?The chloroplast is a small, elliptic shape, and membrane-bound organelle found in the cells of most green plants.
The chloroplast contains green substances known as chlorophyll. The chlorophyll is responsible for absorbing radiant energy from the sun for the process of photosynthesis.
Both the light-dependent and light-independent reactions take place in the chloroplast.
Thus, the production of glucose which is a light-independent reaction takes place in the chloroplast.
