Answer:
The number of phenotypes produced for a given trait depends on how many genes control the trait.
Explanation:
Based on heredity, the number of phenotypes in a population is determined by the number of alleles for that triat as well as the nature of the alleles.
What is a phenotype?A phenotype is a physical expression of a gene.
The phenotype of an organism is influenced by the inherited alleles for that gene that an organism has.
Alleles are alternate forms of a gene.
Alleles may either be;
dominant,recessive, incompletely dominant or co-dominant.The phenotype of that organism will thus depend on the nature of the alleles of that gene or trait.
Therefore, the number of phenotypes in a population is determined by the number of alleles for that triat as well as the nature of the alleles.

O 41 Calories is greater than 410 kcal
O 41 Calories is equal to 410 kcal
41 Calories is less than 410 kcal
It is not possible to compare these two values
From the calculation, we can deduce that 41 Calories is less than 410 kcal.
Given the following data:
Energy in calories = 41 CaloriesEnergy in kcal = 410 kcalTo compare 41 Calories to 410 kcal, we would simply convert the given values to the same base values:
Hence, we would make Calories the base value by converting the value in kcal to Calories as follows:
Conversion:
1000 Calories = 1 kcal
41 Calories = X kcal
Cross-multiplying, we have:
[tex]1000X =41\\\\X=\frac{41}{1000}[/tex]
X = 0.041 kcal.
From the calculation, we can deduce that 41 Calories is less than 410 kcal.

Section 3: For at least one of the sub-problems, propose two solutions based on the information from the lesson and your additional research. In the rationale column, explain how your solution restores the stability and biodiversity of your selected ecosystem.
Removal of invasive species and growing more vegetation can restore the stability and biodiversity of ecosystem.
These two solutions restores the stability and biodiversity of the selected ecosystem because invasive species can capture more resources as compared to local species which leads to the extinction of local species.
While on the other hand, growing more vegetation provides more food to the organisms which ultimately increases the biodiversity of the ecosystem so we can conclude that removal of invasive species and growing more vegetation are the solutions to bring ecosystem in a stable condition.

Explanation:
in what generation does this population reach its carrying capacity
Answer:
The logistic population growth happens as the growth rate declines as the population exceeds the carrying power. The highest number of people in a community that the ecosystem can sustain is carrying capacity.
Explanation:
A population may reach its carrying capacity in any generation, depending on a variety of factors such as the availability of resources, predation, competition for resources, and other ecological and evolutionary processes.
What is carrying capacity?The carrying capacity of a population is the maximum number of individuals that can be supported by a particular environment over a given time period. A population may reach its carrying capacity in any generation, depending on a variety of factors such as the availability of resources, predation, competition for resources, and other ecological and evolutionary processes.
For example, if a population of animals is introduced to a new habitat with abundant resources, it may be able to grow rapidly and reach its carrying capacity relatively quickly. On the other hand, if the population is facing competition from other species or is subjected to predation or other limiting factors, it may take longer for the population to reach its carrying capacity.
It's important to note that the carrying capacity of a population is not a fixed value, and it can change over time due to changes in the environment or the population's own characteristics. For example, if the population grows to a size that exceeds the carrying capacity of its environment, it may begin to experience negative impacts such as resource depletion, disease outbreaks, or other factors that can reduce its size and bring it back down to the carrying capacity.

Observe the cut ends of the flatworms using the hand lens or the dissection microscope immediately after cutting.
What do you see?
Are there distinct differences between the two ends?
Observe the cut ends of the flatworms over a period of several days. Do the flatworm halves continue to exhibit the same degree of difference that was seen right after they were cut in two?
What kinds of changes occur in the flatworms as they recover from having been cut in two?
The above question requires a personal answer about your experience with cutting flatworms. I can't tell you what you saw in this cut, but I'll show you what happens when it occurs.
First of all, you must understand that flatworms are worms with a great capacity for cell regeneration even if several pieces have been cut.
In this case, when a flatworm is cut in half, we can see the following events happen:
At the moment of cutting, the two ends of the flatworm body are equally shaped and are straight ends, without deformations.The ends will not be different if the cut is done accurately, but it may differ slightly.After several days, the ends will present some deformations and will lose the straight shape caused by the blade.Deformations are extremely similar and change similarly.When recovering from the cuts, each side of the flatworm body formed a new flatworm and they are no different, they are the same and they are completely recovered.This is because the cellular regeneration of flatworms is very fast and allows any part of the flatworm's body to create exactly the same beings, as they have the same genetic makeup.

Which hormone is responsible for the development of the male secondary sex characteristics? estrogen progestin progesterone testosterone.
Answer:
It is Testosterone
Explanation:
The hormone responsible for the development of the male secondary sex characteristics is testosterone. Hence option D is correct.
What is testosterone?Testosterone is a hormone primarily produced in the testes of males and to a lesser extent in the ovaries of females and the adrenal glands of both sexes. It is an androgen, or a hormone that promotes the development of male characteristics.
Testosterone plays a crucial role in the development of male reproductive tissues, such as the testes and prostate, as well as in the growth of muscle mass and bone density.
It is also responsible for the development of secondary sex characteristics in males, such as facial hair growth, a deepening of the voice, and the growth of Adam's apple. Testosterone also regulates sex drive (libido) and sperm production.
In females, testosterone is produced in smaller amounts and helps regulate the menstrual cycle and promote bone density.
An imbalance of testosterone levels in either males or females can lead to various health issues, including infertility, osteoporosis, and disorders of sexual development.
Hence option D testosterone is correct.
