Answer:
Increase the genetic diversity by introducing other subspecies of cougar to the population.
Explanation:
- Genetic diversity is the total number of genetic makeup of species. It includes the number of species that have differences within the species and is distinguished from the genetic variability.
- The genetic diversity services allow for the population to adapt to the environment and continue to generate more. Thus introducing the subspecies of cougar can be done to save the species from getting extinct.
The following are the statements that accurately demonstrate the electron transport chain:
1. The electron transfer in the electron transport chain is combined with the proton transfer from the matrix to the intermembrane space.
2. The prosthetic groups, like Fe-S centers, directly take part in the transfer of electrons.
3. The electron carriers in the electron transport chain comprise cytochrome C and ubiquinone (coenzyme Q).
4. The electron carriers are arranged into four complexes of prosthetic groups and proteins.
5. The reactions of the electron transport chain occur in the inner membrane of mitochondria.
Answer: The correct answer is-
A. organs, but no true body cavity.
Based on the presence of body cavity ( also called coelom), multicellular animals can be classified as acoelomates ( no true body cavity), coelomates ( having true body cavity), pseudocoelomates ( false body cavity).
Roundworms are pseudocoelomic. This means that organs are present but the body cavity is not lined by mesodermal epithelium.
Body cavity is present between the external wall of body and the intestine and it baths the different body organs.
Thus, option A) is the right answer.
Nicked circle is the reason.
Explanation:
During recombinant DNA technology the gene of interest is ligated to plasmid DNA by excision with molecular scissors or endonuclease enzyme and ligated with enzyme ligase.
Enzyme ligase catalysed by ATP seals the nicks by making phosphodiester bonds in the ds or ss DNA and release of ADP.
The ligation in the plasmid did not occur properly hence the replication is interrupted hence no new plasmids with gene of interest replicated in the ligation carried out.
