Answer:
The correct answer will be option-Selective survival and reproduction is a requirement of evolution by natural selection.
Explanation:
Evolution is a slow process of change in the heritable features of species over a successive generation of time.
The process of evolution takes place during a long period of time only when the advantageous mutations are passed on to the generations and become established.
The mechanism of this process is natural selection which increases the reproductive rate as well as the survival rate of the species.
Thus, the selected option is the correct answer.
Answer:
Small intestine, liver, bile and lipase.
Explanation:
Digestion of fat occurs in the small intestine. Its digestion occurs with the help of bile, that is made in the liver. Bile breaks the fat into small drops that are easier for the lipase enzymes to change it. Lipase enzymes is a type of enzymes that works only on lipids and lipids are broken down into fatty acids and glycerol. These substances are absorbed by our body and used it for producing ATP for the body.
The population of the ground squirrels will be limited by the population of the hawks. The population of the hawks, thus, will be a limiting factor for the population of the ground squirrels. The Hawks are the birds of prey that feeds on squirrels. With the increased number of hawks in the same area as them will put these squirrels in danger. The population of the tree squirrels, however, will have no affect on the population of the ground squirrels. The genetic variability and breeding season are not limiting factors for their population either.
Hence, the correct answer is 'option B - a population of hawks'.
Answer:
-Because membranes are fluid, membrane proteins and phospholipids can drift about in the membrane.
-The diverse proteins found in and attached to membranes perform many important functions.
-The framework of a membrane is a bilayer of phospholipids with their hydrophilic heads facing the aqueous environment inside and outside of the cell and their hydrophobic tails clustered in the center.
Answer:
Recreation ans scenic areas for tourism.
Explanation:
- As the ecosystem provides a certain amount of services as habitat, healthy soil and clean air, freshwater nutrient cycle s and human goods like culture, recreation, and health. All these are benefits that humans freely gain from the natural ecosystem either be agro, forest aquatic or grasslands, etc.
