<span>The correct option is A. Founder's effect is the reduced genetic variability that occur as a result of population production from a small number of colonizing parents. The founder's effects is one of the ways by which nature can randomly produce new species from existing population.</span>
Answer:
A. Warm sir masses over the equatorial regions rise more quickly than air masses over polar regions.
Explanation:
Carbohydrates are your body’s main source of energy. The amount of carbs a man should consume daily depends on his age and activity level. The Institute of Medicine suggests adults to eat at least 130 grams of carbs a day. But If you’re a competitive athlete like Shana, you need additional amount.
<span>A study made by The Academy of Nutrition and Dietetics recommends a 2.3 to 4.5 grams of carbohydrates per pound of body weight each day, to athletes depending on the intensity of training. Therefore, Shana who weighs 135 lbs, needs approximately 310.5 grams carbohydrates daily for her physical workouts. </span>
Organisms need to take food because you need it to survive.
Autotroph --
<span>Autotroph is </span>an organism that can form nutritional organic substances.
Complete question:
Which of the following pairs represent homologous structures?
- Wings of grasshopper and forelimbs of flying squirrel
-
Tentacles of Hydra and arms of starfish
-
Forelimbs of a bat and forelegs of a horse
-
Wings of a bird and wings of a moth
Answer:
3. Forelimbs of a bat and forelegs of a horse
Explanation:
Homologous characters are structures with the same basic elements. Their position in the body and the relations with adjacent structures are also the same in different organisms, and they even share the same embryological development.
These structures might show variations between the organisms exhibiting them. Variations might be related to their function and to the environment in which the organism lives. The function they accomplish is not necessarily the same in all the organisms involved.
These homologous characters are present in organisms related that share a common ancestor.
For example, whales, humans, and cats all have the same bones in the same order, but they matured differently in later embryological development.
Among the options, the only possible pair that represents homologous characters is option <em>3. Forelimbs of a bat and forelegs of a horse</em>. Both structures are the anterior extremities of the animals and share the same bones, even though they might differ in the development degree. Forelimbs and forelegs have the same position and relation with other structures in the body, and embryologically, they are the same.
