The medical terms that ends with ae letter combination shows that it is the plural form of the term.
for example bulla is a medical term which is used for blisters which are filled with fluid, when there is more than one bulla we use the word bullae, that is the plural form of the word bulla.
The answer would be : B. proteins
mRNA has the codes to make each type of proteins. When our body need a certain type of protein, mRNA will detect it and match the code according our needs
hope this helps
Complete question:
Snow leopards live in the high reaches of the Himalayas and have several adaptations to deal with living most of the time in snow. They have wide paws with hair between the toes to allow them to run on top of the snow crust. Assume that wide paws (W) and hair between the toes (T) are both dominant traits and are on the same chromosome. Suppose that two snow leopards, heterozygous for both traits, mate. Suppose further that in the female, the two dominant alleles are on the same chromosome of the homologous pair, while in the male, each chromosome of the pair has one dominant and one recessive allele.
1) What percentage of each of the following genotypes will be produced?
- WwTT:
- WwTt:
- Wwtt:
- wwTT:
- wwTt:
- wwtt
2) How many of the offspring (assume 4 cubs) will have narrow paws with hair between the toes?
Answer:
1) Percentage of each of the following genotypes
- WWTT: 0
- WWTt: 1/4 = 25%
- WWtt: 0
- WwTT: 1/4 = 25%
- WwTt: 0
- Wwtt: 1/4 = 25%
- wwTT: 0
- wwTt:1/4 = 25%
- wwtt: 0
2) Offspring with narrow pows: 1 of four individuals.
Explanation:
<u>Available data:</u>
- wide paws (W) and hair between the toes (T) are both dominant traits
- narrow paws (ww) and no hair (tt) are bothe recessive traits
- Both traits are on the same chromosome.
- Female: W and T on the same chromosome of the homologous pair, w and t on the other chromosome.
- Male: W and t on the same chromosome of the homologous pair, w and T on the other chromosome.
Cross: Between two heterozygous individuals

F1) Genotypes:
Phenotypes:
- 2/4 = 1/2 = 50% wide paws with hair (W-T-)
- 1/4 = 25% wide paws with no hair (W-tt)
- 1/4 = 25% narrow paws with hair (wwT-)
Answer:
a) Two reasons why polythene bags are not environment friendly are as following:
- Plastic bags are made up of non-renewable materials such as polypropylene and their manufacturing and disposal cause greenhouse gases to release in the environment and contribute to global climate change.
- Polythene bags or Plastic bags are non-degradable and break into small pieces in the environment which are then consumed by wildlife or run off into oceans.
b) Yes, the decision of using paper bags is correct as it will minimize the use of plastic bags and also reduce the environmental pollution caused by plastic waste. Paper bags can be reused or recycled again and again and they are easily degradable in the environment causing very less or no pollution.
c) The values associated with the ban on use of polythene bags is to establish a sustainable environment for our present and future generation. It will reduce environmental pollution and will minimize the effect of global warming.
