In a population of plants, the allele for long stems (S) is completely dominant over the allele for short stems (s). If 35% of t
Sergio [31]

Answer:

The correct answer would be 48 percent.

It can be solved by using the Hardy-Weinberg equation.

p² +  2pq+ q²  = 1

p + q = 1

where, p² represents homozygous dominant's frequency that is, SS in this case,

q² represents homozygous recessive's frequency that is, ss in this case,

2pq represents heterozygous dominant's frequency that is, Ss in this case.

p represents dominant allele's frequency and q represents the recessive allele's frequency.

Now, the percentage of homozygous recessive or short stems is 35%. Therefore, the frequency of homozygous recessive would be 0.35.

Thus, the value of q² = 0.35

So, q = \sqrt{0.35} = 0.59 which is approximately equals to 0.6.

As p + q = 1 so, q = 1 - 0.6 = 0.4

The frequency of heterozygous (Ss) = 2pq = 2(0.6)(0.4) = 0.48

Hence, the frequency of heterozygous would be 48 percent.

Explanation:

Motivation is the urge that fuels and directs human with the energy to accomplish a given task. Motivational theory is accustomed  with the role of  searching for what drives individuals to work towards a goal or a task.

The drive reduction theory explains  physiological ideology  required bring out  an aroused tension state that motivates an organism to satisfy the need.

Instincts Theory reflects innate and  fixed pattern of complex behavior in animals. For example, making holes of crabs for safety.  

Optimum Arousal Theory drive people to engage in certain activities in the quest to keep up with an optimum level of physiological arousal.

Hierarchy of motives: According to Maslow's pyramid, hierarchy of motives is explained based on need to satiate or quench the least physiological needs in order to be active before subsequent level needs.
