The Truck will take more force to stop the truck moving at a speed of 55mph weighing 4000kg has alot more momentum and will require a force equal to its speed and mass to stop it therefore the truck is the most obvious answer hope this helped bud
<h3><u>Answer;</u></h3>
Label A; Mitochondria.
Label B; Nucleus.
Label C; Golgi apparatus.
Label D; Rough endoplasmic reticulum
<h3><u>Explanation;</u></h3>
- All the above are various organelles in a eukaryotic cells each carrying different cellular activity to enhance the functioning of a cell.
Label A; Mitochondria.
- <u>Mitochondria</u> is the powerhouse of the cell which converts glucose to energy rich molecules of ATP, through the process of cellular respiration.
Label B; Nucleus.
- <u>Nucleus</u> contains the genetic material or DNA, RNA , nucleolus, chromatin fibres and proteins. It contains the chromosomes which control the hereditary characteristics.It also regulates all the activities of the cell.
Label C; Golgi apparatus.
- <u>Golgi apparatus;</u> they are also called Golgi bodies. They function in modifying, sorting and packaging of proteins for secretion. They are also involved in the transport of lipids around the cell, and the creation of lysosomes.
Label D; Rough endoplasmic reticulum
- <u>The rough endoplasmic reticulum</u> provides surface for protein synthesis. It is also used to transport cellular contents from one cell to another.
- The risbosomes attached on the rough endoplasmic reticulum are resposible for the protein synthesis through the process of translation.
Answer:
"
Natural gas does not produce greenhouse gases as other energy sources do."
Explanation:
The answer, "Coal deposits are found on nearly every continent and mining coal poses few risks." shows only how it can be a better option, but does not show how it can benefit.
The answer, "Petroleum is relatively inexpensive compared to other forms of energy." only shows how it can be a better option, but does not show how it can benefit.
The answer, "Nuclear power increases water vapor in the atmosphere." does not clearly state how this benefits us.

Answer:
(a) 1/2; (b) no
Explanation:
Glucose-6-phosphate dehydrogenase deficiency (G6PD) is an X-linked recessive disorder and the woman's father was diseased so it means that woman is a carrier of the allele but has normal phenotype. It means that she will have XXᵇ genotype.
In contrast to this, her husband is diseased so his genotype will be XᵇY.
The Punnett square diagram related to the cross is attached.
(a) Proportion of their sons expected to be G6PD is 1/2:
They both may give birth to 4 progeny with genotypes XXᵇ, XᵇXᵇ, XY and XᵇY. It means they both may have 2 sons out of which one with genotype XᵇY will be diseased while the one with genotype XY will be healthy. So the proportion of their sons having G6PD is 1/2 or 50%.
(b) If the husband were G6PD deficient, the answer will not change.
The reason behind this is that this disease is caused by an allele located in X chromosome. But father contributes only Y chromosome to his son not X chromosome. The X chromosome will affect the genotype of his daughter not son that is why answer will not change. It means they will still have 1/2 of their sons diseased.
Some of the important questions to be asked should be: Is the procedure of obtaining the results accurate? If not, by how much is its reliability? Are the results useful for further scientific research? What can you recommend to others who might want to make the same scientific conclusions?
