Answer:
radioactivity will not be able to tell the difference between the DNA and proteins
Explanation:
It seems that the experiment will fail to show what Hershey and Chase showed because they modify some of the aspects. These modifications will cause changes to the results, the main one being that radioactivity will not be able to tell the difference between the DNA and proteins. This is because Amino Acids are proteins that also contain nitrogen atoms, thus labeling the nitrogen would include all DNA and proteins. This being the main reason why Hershey and Chase decided to label the DNA instead.
Answer:
B
Explanation:
Sickle cell anemia is an autosomal recessive trait, meaning two recessive alleles must be acquired by the child (one from each parent) for them to be affected with the disorder.

The fir tree can be found in the coniferous forest biome, and the cactus can be found in the desert biome.
Option C.
<h3><u>Explanation:</u></h3>
Both the cactus and fir trees are having modified tree leaves due to the same purpose - saving water.
The fir trees are found in the coniferous forests which are mainly seen in mountains or in the temperate region. Both the regions face very cold climates and frequent snowfalls in every years. This is why there's a lack of water in the surroundings. This is why they need to save water and minimize transpiration.
Whereas the cacti are found in desert or semi arid regions where water is itself very scarce and temperature is either very high or very low. So they have their leaves converted into spines which help to reduce transpiration.
TRNA reads codons from mRNA and then brings attached amino acids accordingly. Amino acids are connected in long chains called proteins.
a) volume in cm³ = 20 × 42 × 42 = 35280 cm³
b) volume in m³ = 0.2 × 0.42 × 0.42 = 0.03528 m³
c) volume in ml³ = 200 × 420 × 420 = 35280000 ml³
d) volume in litres = 0.02 × 0.042 × 0.042 = 0.00003528 l³
e) Density = Mass / Volume
Mass = Volume × density
= 0.00003528 × 1
= 0.00003528 × 1000
= 0.03528 grams
f) Mass in kilo gram = 0.00003528 kg
