Answer:
q1 : ribosomes because they are responsible for protein synthesis
q2 : by transporting potassium ions into the cell and sodium ions out of the cell maintaining a concentration gradient
q3 : seawater contains a high concentration of sodium and chlorine ions that the Atlantic cod gets rid of by actively transporting them out of its body
Answer: The answer for the first one is
1: Eukaryotic
2: mitochondria
3: carbon dioxide, water, atp
4: glucose, oxygen
5: Glucose.
Answer: c. Air pollution
Explanation:
There was a heatwave in Europe during the early years of the 21st century that killed tens of thousands across the continent and thousands in France.
Air pollution was blamed for having made the situation worse because the pollutants in the air acted to prevent heat from escaping back into the atmosphere which led to increased heat on ground and therefore a heat wave.
<span>People in some countries eat little or no meat. They are getting much of their protein from vegetarian protein sources.
</span><span>Fish is one of the major sources of animal protein around the world.
</span><span>Fish is the main source of animal protein in many developing countries, providing over 50 percent of the animal protein consumed in some areas, according to the Food and Agriculture Organization.
</span>In some developing nations, the percentage <span>of animal protein from the fish in the diet can be high as the percentage of animal protein from red meat (beef and pork) in America.</span>
That's intimidating, lol!
Okay so choice A says that #8 is heterozygous for the trait which means for example it would have the genotype Aa. She's a female witht he dominant trait. This is a possibility.
Choice B says #10 is heterozygous, but if it has the recessive trait it would have to have the geotype aa which is homozygous so this one is wrong.
Choice C says #13 is homozygous dominant which means the genotype will be AA. The individual can still have the dominant trait without having the AA genotype (it can also be Aa) so this one is wrong.
Choice D says that #3 is homozygous dominant but like with choice C, the chart doesn't specify the genotypes of each so it'd be a guess to say that #3 is homozygous. This is wrong.
This means that choice A is true!
