How does nature “select” phenotypes, such as bird beaks? Check all correct explanations. 1. Organisms can choose the genes that

will make them most successful. 2. The environment influences which alleles an organism can pass on to its offspring. 3. Traits that suit the environment enable an organism to reproduce in greater numbers. 4. Traits that do not suit an environment make it harder for an organism to stay alive and reproduce.

Answer:

The correct answers would be options 3 and 4.

Natural selection refers to a natural phenomenon by which organisms with survival traits tend to survive and reproduce more as compared to the organisms which lack such traits.

Due to this differential reproduction, survival traits tend to pass on to the offsprings and over several generations the phenotypic frequency of the population changes.

If the current population size of bison is 3,652 and the maximum growth rate of the population is 0.28, calculate the population
s344n2d4d5 [400]

<u>Given:</u>

Present population of bison = 3652

Maximum growth rate = 0.28

<u>To find:</u>

The population of bison after one year.

<u>Solution:</u>

The future population can be calculated with the help of the following formula,

P_F=P_P\times(1+r)^n

where P_F is the future population, P_P is the present population, r is the growth rate and n is the number of years.

On substituting the given values in the formula we get,

\Rightarrow P_F=3652\times(1+0.28)^1

\Rightarrow P_F=3652\times1.28\rightarrow4674.56\approx4675

Therefore, the population size of bison after one year is 4675. The park does not have to control the population because the growth rate is on an average scale.

Which of the following best explains how the light reactions of photosynthesis generate ATP?
frutty [35]

Answer:

B. A proton gradient drives the formation of ATP from ADP and inorganic phosphate via ATP synthase.

Explanation:

Light reaction of photosynthesis includes the splitting of water in the presence of sunlight and electron transfer from PSII to PSI via an electron transport system. During the transfer of electron through cytochrome of the electron transport system, the proton concentration gradient is generated across thylakoids. The proton concentration gradient is harvested to drive ADP phosphorylation by the catalytic site of ATP synthase accompanied by downhill movement protons through its proton channels.

What might happen if you make a hole using a pointed object to any of the two small<br> balloons?
luda_lava [24]

Answer:If the balloons are filled with air all of the air will try and escape from the balloon out of the hole but if the balloon is filled very tightly with air it will burst because there is too much pressure trying to escape such a small hole so it goes PoP!

Explanation:

Not researched this answer was from common knowledge so if you have a correction or better answer please inform me I will be happy to learn more.
