He noted that each finch species had a different beak type depending on the island's food supply.

Darwin's Finches Darwin observed that the shape of the beaks of different finch species varied. He hypothesized that the beaks of ancestral species adapted over time to equip finches to acquire various food sources.  According to Charles Darwin, who visited the Galapagos Islands. Noted that unique creators were similar from island to island and they were perfectly adapted to their environment.

According to the question the cross between the two pea plants with the genotype RrYy and rryy where R for round seeds and r for recessive form that expressed wrinkled seed character. The other character of this dihybrid cross is the color of the seds Y for green and y for yellow seeds.

The cross is shown in the image attached that suggests that phenotypic ratio would be 1:1:1:1 as RrYy, Rryy, rrYy, and rryy.

Thus, the correct answer is : 1:1:1:1.

A fox is a type of mammal that is related to dogs. How does a fox most likely respond to hot air temperatures in a way that ecto
sveta [45]

Answer:

By panting or breathing heavily.

Explanation:

<em>An ectothermic animal is one whose body temperature depends on the temperature of the external environment.</em>

The body of ectotherms regulates temperature depending on the temperature of the external environment where such animal finds itself.

Hence, when the temperature of the external environment rises as a result of hot air, the body of an ectotherm (that is homeothermic, that is, maintain a relatively constant body temperature irrespective of the temperature of the external environment) will adjust so as to keep its temperature relatively constant.

Dogs generally pant (breathe heavily) to bring their body temperature back to normal whenever it rises beyond normal due to rigorous physical activities or high external temperature.

<em>Hence, a fox will most likely pant in response to hot air temperature just like dogs.</em>

Considering the ATP cycle, which of the following would have the most potential energy to perform work for cell activities? A. A
Mumz [18]

Answer:

ATP

Explanation:

We are well aware of the fact that ATP is considered to be the energy currency of the cell. If we talk about cell activities it needs an energy input. No doubt that H+ ions play an important role in electron transport chain step of the production of ATP, but the ultimate product which is used by the cell is ATP.

AMP and ADP are also energy sources but they contain less amount of energy as compared to ADP because in ATP there are three phosphate bonds and each bond upon breakage releases almost 7.3 kj/mol of energy. So it definitely will be more in ATP as compared to ADP and AMP.


Hope t help!
