This is a weird question because people still argue over whether you inherit musical ability. I know for a fact that tongue rolling is inherited though.

Hope that helps.

Gekata [30.6K]

Answer:

1600 calories consumed daily

Explanation:

we have to:

1 pound of weight (0.45 kg) equals 3,500 calories.

paraelll we suppose the formula

calories / days of the week = 3500/7 = 500 calories per day.

so there are 500 calories that you must reduce from the diet, so according to calorie consumption:

2100-500 = 1600 calories consumed daily

Answer:

1) weathering is the process of something wearing away and breaking into smaller pieces, erosion is where things like water, wind, ice and gravity wear away rocks and soil and moves it from one location to another.

2) chemical weathering is when the rock changes a mineral and mechanical weathering is when it changes physically, like breaking into smaller pieces

28. <u>Answer</u>: All mutations do not affect the organisms due to the following reasons:-

1. The DNA consists of both coding and non coding regions. The coding regions are known as exons and non coding regions are called as introns. The <em>non coding regions </em>do not make up the protein. Thus, if the mutations occur in non coding regions they do not affect the organism.

2. There are some mutations that result in the change of the codon but the new codon formed codes for the same amino as the previous one. This is possible because of the degeneracy of genetic code. For eg, AAA codes for lysine, however if the mutation changes this code to AAU then this also codes for lysine. Such mutations are called as <em>silent</em> mutations.

3. There are some mutations which result in the change in amino acid however the new amino acid formed is similar to the previous one in its properties for e.g leucine and isoleucine. Such mutations are called as <em>neutral</em> mutations and they do not affect the organism


29. <u>Answer</u>: 1. The process of mitosis results in the formation of <em>two diploid cells</em> whereas meiosis results in the formation of <em>4 haploid cells.</em>

2. The process of mitosis takes place to produce copies of the <em>body cells </em>whereas the process of meiosis takes place to produce the <em>gametes</em>.

<u>Explanation</u>:-

  • <u>Mitosis</u> is a process in which a cell undergoes a single round of division to produce two identical copies of itself . It occurs in 4 phases Prophase, metaphase, anaphase and telophase. This process occurs in the body cells.
  • <u>Meiosis</u> is a process in which a cell undergoes two rounds of cell division to produce 4 copies of haploid cells from a single diploid cell. This process takes place for the formation of gametes.

29. <u>Answer</u>:

<em>Pros</em>

1. Genetic engineering helps us to tackle several diseases. There are many diseases which are caused due to genetic mutations. Genetic engineering helps us to rectify these mutations and hence combat such diseases.

2. Genetic engineering helps us to produce new foods which can withstand adverse conditions such as high/low temperatures, low rainfall, are disease and pest resistant etc. This, genetic engineering helps to significantly improve crop production.

<em>Cons</em>

1. Genetic engineering leads to a decrease in genetic diversity.

2. It can lead to a decrease in the nutritional value of food as genetic engineering often causes an accelerated growth of animals and hence, the nutritional valie of poultry foods is compromised.
