<span>Ethology is a branch of zoology concerned with the study of animal behavior. Ethologists take a comparative approach, studying behaviors ranging from kinship, cooperation, and parental investment, to conflict, sexual selection, and aggression across a variety of species.</span>
Answer: Option A
<u>Explanation:</u>
As temperature increases the rate of enzyme activity increases until it reaches approximately 37 degrees Celsius. As temperature increases beyond 37 degrees Celsius, the enzyme activity decreases. The activity decreases because the enzyme denatures.
Any enzyme has certain temperature, pH and pressure to maintain its activity. Only at the ideal or ambient parameters the enzyme works. Most of the enzymes that are present in the human body gets activated by 37 degrees and gets denatured beyond that temperature.
Answer:
As well as producing hormones, vaccines and other drugs genetic engineering has the potential to cure genetic diseases through gene therapy. The same techniques that are used to produce drugs can also have industrial applications such as producing enzymes for laundry detergent, cheeses and other products.
Explanation:
Answer:
A. It allows two populations to evolve separately.
Explanation:
Geographic isolation is theorized to have catalyzed the formation of new species. Let’s say groups A and B of a bird species get separated by something, and they can’t cross between to interbreed or exchange alleles.
We describe this as no gene flow, which is the opposite of choices C and D. Because of this, they may diverge if given enough time due to the difference in environmental pressures, because they’re now in different environments.
B is incorrect because it doesn’t apply.
1. They have a slimy skin in which the oxygen gets dissolved. 2. The frog have lung instead of gills 3. They have enormous no. of nerves which help them to breathe through skin
