Explanation:
For question no 19
Force (F) = 20N
distance (d) = 5m
Work = F * d
= 20 * 5
= 100 J
Now
For question no 20
D. No matter how much force is applied the object must have motion for work to be done.
Answer:
Dung beetles lives in the animal dung and take nutrients from the undigested substances present in the dung. This dung is mixed with the soil by the beetle to increase the fertility of the soil. These nutrients is taken by plants with water through roots and makes their food in the form of carbohydrate from it in the process of photosynthesis. This carbohydrate is stored in different parts of plant body.
if you told me what process i could help you - post a new question and ill try to help you
When a DNA sequence alteration results in a stop codon rather than a codon that specifies an amino acid, it is known as a nonsense mutation. This is rarely seen in 10% of patients with genetic disease.
<h3>What is nonsense mutation?</h3>
A nonsense mutation in a DNA sequence causes a premature stop codon, also known as a nonsense codon, in the transcribed mRNA as well as a shortened, ineffective, and typically nonfunctional protein product.
Because stop codons, also known as nonsense codons, signal the completion of protein synthesis rather than encoding for an amino acid, they are the source of the term "nonsense mutation."
Examples of illnesses for which nonsense mutations have been implicated as contributing factors include: Cystic fibrosis (produced by the G542X mutation in the cystic fibrosis transmembrane conductance regulator); (CFTR) Beta-globin (thalassemia) Hurler disease.
