.Most life-forms that existed on Earth have become extinct.
<span>.Dinosaurs existed on Earth for more than 544 million years.
Both these statements are well suported by fossil record.</span>
Yes animal cloning is a genetic technology.
3. Currently somatic cell nucleus transfer technique is used in animal cloning.
3. The livestock copuld be increase, high protein meat and milk is obtained and saving endangered species from extinction.
4. The mating process will stop in cloning process which is unethical.
Explanation:
1. Animal Cloning is a genetic technology in which genetically identical clones of animals are produced from somatic cell nuclear transfer technique.
3. Currently somatic cell nuclear transfer or Roslin technique is used as follows:
In somatic cell nuclear transfer a nucleus from a somatic cell is taken and injected into an unfertilized ovum of the surrogate mother. Somatic cell could be taken from udders, blood,skin etc.
The somatic cell and nucleus is allowed to fertilized artificially by providing medium and let it divide to become an embryo and placed in surrogate mother to develop.
4. The breeds with superior yields are obtained from this technique as follows:
The endangered species could be cloned and prevented from extinction.
Livestock production can be increased from healthy donors producing healthy offsprings.
High milk and meat content yielding breed could be cloned.
5. Ethical implications of the technology are:
The use of animal in animal cloning will be unethical as only one parent is involved. The genetic variation will cease this way which occurs naturally. The mating process will stop in cloning so it is unethical and against nature's law.
<h2>Answer is option " 2 & 4"</h2>
Explanation:
- Two types of posterity can be created subsequent to mating: parental and recombinant. Recombinants are created because of the traverse of non-sister chromatids at the hour of gamete arrangement. Here, mating happens between m+g/mg+ female and mg/mg male so the posterity would be separated as follows:
- m+g/mg : Parental
- mg+/mg : Parental
- m+g+/mg : Recombinant
- mg/mg : Recombinant
- m+g+/mg (wild sort) and mg/mg (smaller than usual wings, garnet eyes) are the recombinants thus they were created because of the hybrid occasion.
- Hence,the right answer is option 2 & 4 "wild type and miniature wings,garnet eyes"
The agent would prescribe the fresh-frozen platelets. This is
a blood produce made from the liquid share of entire blood. It is used to treat
circumstances in which there are low blood coagulation factors (INR>1.5) or small
levels of other blood proteins.
Answer: B). NADH and ATP
Explanation: Glycolysis is a ten enzyme catalyzed reaction in which glucose a six-carbon sugar is broken down into two molecules of three-carbon pyruvate. Glycolysis is divided into two phases: the preparatory phase constituted by the first five reactions and the pay off phase constituted by the remaining five reactions. Energy-carrier molecules are produced in the pay off phase. In this phase, four molecules of ATP and two molecules of NADH are produced. NADH is produced in a reaction catalyzed by glyceraldehyde 3-phosphate dehydrogenase in which glyceraldehyde 3-phosphate is converted to 1,3-Bisphosphoglycerate. ATP are produced in a reaction catalyzed by phosphoglycerate kinase in which 1,3-Bisphosphoglycerate to 3-phosphoglycerate, and in a reaction catalyzed by pyruvate kinase in which Phosphoenolpyruvate is converted to pyruvate.
