Answer:
Certain plants contain compounds similar to ecdysone which serve as a defense against insects. False
Juvenile hormone levels are high in insect larvae, but must decrease in order for metamorphosis to occur. True.
Chemicals similar to ecdysone and juvenile hormone are widely used commercially to control insect pests. True
Explanation:
The plants produce toxic chemicals such as terpenoids, alkaloids, anthocyanins, phenols, and quinones as a defense against insects. Juvenile hormone levels are high in insect larvae but its concentration decrease when the insect transform into adult stage and in order to occur metamorphosis. Ecdysone and juvenile hormone are widely used as insecticide because it prevents the insects to transform from larva to adult so if they can't mature they can't harm the plants or other things of our environment.

what are the merit of
indigenous education
Answer:
It was a way to protect, preserve and develop traditional indigenous skills and cultures. Education was a significant step towards empowering indigenous peoples to participate more fully in their communities. It was an indispensable asset to attain freedom and social justice.
Answer:
The core of indigenous education in Africa focused on providing each individual in the community with knowledge, practical skills and attitudes in order to prepare them to for his/her role in the society. It is a holistic system, in which apprenticeship, story telling, proverbs and myths played an important role. Traditional education developed in the ‘learners’ a sense of obligation towards the community and made learners to appreciate the history, language,customs and values of the tribal group, keeping in touch with their heritage, their cultural roots. Western education alienates young Africans from their cultural heritage.
Night blindness (n) is a sex-linked recessive trait. A woman who is night blind marries a man who is not night blind. What are the genotypes of both individuals?
Answer:
Genotype of night blind woman - XnXn
Genotype of normal man - XY
Explanation:
Given
Night blindness (n) is a sex-linked recessive trait. Let us say it is X linked recessive
In this case a man with XY genotype having a diseased X allele will be night blind while a woman will have night blindness if both the X allele are diseased . In case if only one X allele is diseased in women then, she will be a carrier of night blindness defect
Genotype of night blind woman - XnXn
Genotype of normal man - XY

Which of the following is a result of glycolysis?
a.Usage of oxygen as a strong oxidizer
b.Production of CO2
c.Conversion of FAD+ into FADH2
d.Splitting of a glucose molecule to form two G3P molecules
The main result of glycolysis is the splitting of a glucose molecule to form two G3P molecules. The Option D.
What is the main result of glycolysis?Glycolysis, the initial step in cellular respiration involves the breakdown of glucose. One of the key outcomes of glycolysis is the splitting of a glucose molecule into two molecules of glyceraldehyde-3-phosphate (G3P).
This process occurs in the cytoplasm and does not require oxygen. Glycolysis serves as the primary source of energy production in anaerobic conditions and plays a crucial role in both aerobic and anaerobic cellular respiration.

Which of the following best describes the difference between population size and population density?
A. Population density measures the abundance of an organism, whereas population size measures the distribution
B. Population size measures the abundance of an organism, whereas population density measures the distribution
C. Population size measures abundance, but population density measures how rapidly the size changes
D. Both variables measure abundance, but population density takes the into account the size of individuals, not just the number of individuals in the population
E. None of these descriptions are correct
Population size refers to the number of individuals, while population dendity refers to the number of individuals per unit of area or volume. The correct option is E. None of these descriptions are correct.
------------------------------------------------
Before answering the question, let us review the concepts of population size and density.
Population size refers to the number of individuals composing a population.Population size might determine the destiny of the population.
A small population has more chances to get extinct than a bigger-sized population.
Density refers to the average number of individuals of the same species per unit of area or volume. This measure may be more significant than population size.
To estimate population density there are two possible methods: Direct methods and indirect methods.
Abundance indexes are the parameters related to density, and they reflect changes that might happen in the target population density. They are commonly used to compare population sizes.
According to these concepts, the correct option is E. None of these descriptions are correct.

and flowering plants. Use the above pictures and what you learned in your science class to answer the follow
• Construct an explanation on how pollinators and flowering plants interact and affect each
other.
• What do you predict would happen to flowering plants if they blended into their
surroundings? Explain.
pls help me. i beg you
Answer:
The pollinators help spread the pollen of the flowering plants to help them reproduce. If the flowering plants blended into their surroundings, the pollinators would not be able to identify the flowering plants, and the plants would eventually die off or become extinct.

The service box is an area on the court that 1 point the person serving must stand in. the ball must land in to be a playable serve. the person returning the serve must be standing in before a server can serve
Answer:
Both players on the serving doubles team have the opportunity to serve and score points until they commit a fault *(except for the first service sequence of each new game).
The first serve of each side-out is made from the right-hand court.
If a point is scored, the server switches sides and the server initiates the next serve from the left-hand court.
As subsequent points are scored, the server continues switching back and forth until a fault is committed and the first server loses the serve.
When the first server loses the serve the partner then serves from their correct side of the court (except for the first service sequence of the game*).
The second server continues serving until his team commits a fault and loses the serve to the opposing team.
Once the service goes to the opposition (at side out), the first serve is from the right-hand court and both players on that team have the opportunity to serve and score points until their team commits two faults.
In singles the server serves from the right-hand court when his or her score is even and from the left when the score is odd.
