What phrase from the selection helps you understand the meaning of “composes”?
A variegated leaf with green and yellow patches is used for an experiment to prove that chlorophyll is required for photosynthesis. Before the experiment the green portions (A), and the yellow portions (B), arte observed. What will be the colour of „A‟ just before and after the starch test? Also write the equation of photosynthesis and mark, well ash molecule the by-product is obtained.
Answer: The colour of A before the starch test is GREEN while after the starch test is BLUE- BLACK. The equation for photosynthesis is
6CO2 + 6H2O → C6H12O6 + 6O2.
Explanation:
PHOTOSYNTHESIS is the process by which green plants use energy from sunlight to manufacture their own food. It is a building up process since simple inorganic compounds such as carbondioxide and water are built up into large organic compounds such as glucose and OXYGEN is given off as a by product.
Oxygen given out in photosynthesis occurs in the light stage during the process of photolysis of water. This occurs when the chlorophyll traps, absorbs and captures light energy and become energised. The energised chlorophyll supplies energy which is to split molecules of water into hydrogen ion ( H+) and hydroxyl ion ( OH-). The hydroxyl ion is reconverted to water and oxygen is given out as a by product.
To show that chlorophyll is NECESSARY for photosynthesis, a variegated leaf with green and yellow patches is used for an experiment.
The green portion is marked A and the yellow portion marked B. The leaf is tested for starch using the procedure below:
--> place leaf in boiling water for half a minute to kill it.
--> decolorize leaf by placing it in hot alcohol.
--> dip decolorize leaf in hot water to soften it.
--> place leaf on tile and add iodine solution to it.
RESULT: It would be found that only the green parts contain starch as blue+black colouration is observed while yellow area is unaffected by iodine.

2. FSH and LH stimulate the follicles to develop and the oocyte to produce estrogen.
3. Rising estrogen levels suppress FSH production and development of other follicles.
4. A spike in LH causes the follicle to rupture
5. High progesterone levels maintain the endometrial lining of the uterus.
6. A breakdown of corpus luteum causes progesterone levels to drop.

what ways do we use patterns of classification in science? give examples
Answer:
Classification is the way scientists use to categorize and organize all of life. It can help to distinguish how similar or different living organisms are to each other
Explanation:
Patterns are used in science to classify objects or phenomena into groups. There are patterns of both similarity and difference.
What is classification?Classification is the way scientists use to group and categorize objects, phenomenon or life forms. It can help to distinguish how similar or different living organisms are to each other based upon the pattern of their structure and organization.
Patterns are regular and intelligible forms , sequences, or structure that found throughout nature. Scientific questions may be generated when scientists observe a pattern of events or when something does not match an established pattern.
For example, the frozen water in an iceberg is arranged into a regular, repeating crystal structure—a pattern of similarity. Young children can observe a common pattern of difference, the differences between adult animals and their offspring.
Thus, it is clear from above explanation, the ways to use patterns of classification in science.

Explain the role of both biotic and abiotic factors within a nutrient cycle.
Answer:
Answer. Biotic factors are the living things in an ecosystem so they do not recycle. Abiotic factors are the different physical and chemical components available like temperature, air, water, minerals, rocks,and PH. Not ll of them are recycled.
The role of both factors within a nutrient cycle is very important because nutrients cycling through biotic and abiotic systems constantly.
Explain the role of both biotic and abiotic factors within a nutrient cycle?Plants, animals, microorganism and organic matter are the biotic locations of nutrients while on the other hand, the atmosphere, water, and soil represent the abiotic locations. Nutrients are constantly moving or cycling through biotic and abiotic systems.
So we can conclude that the role of both factors within a nutrient cycle is very important because nutrients cycling through biotic and abiotic systems constantly.

difene the meaning of the phrase entry requirements to higher education institutions and state four reasons why knowing the entry requirements is important
Answer:
1. Entry requirements to higher education are the necessary and important criteria that students intending to acquire higher education must attain before they can be granted admission.
2. Four reasons why knowing the entry requirement is important include;
a. It helps the students chose the right courses in high school.
b. It provides a standard for the universities to evaluate students objectively.
c. It ensures the admittance of students to courses suited for their capabilities and strengths.
d. It prepares students for the tasking academic environment by ensuring that they have a background knowledge of their chosen course.
Explanation:
Before students can be granted admission into schools chosen by them, they must meet certain standards to be deemed qualified by the admitting institution. Knowing these standards on time gives the students a sense of purpose and helps them to develop skills and abilities that make them qualified for admission into these schools.
It also helps the university choose the right students for different courses. Studying ahead to have the required certificates for admission helps the student gain background knowledge of their future course.

Explanation:
In un competitive inhibition, the inhibitor binds to an allosteric site of a enzyme which is usually present at the enzymes substrate complex.
While in competitive inhibition, an inhibitor binds to the enzyme at its active site and hence restricts the substrate from binding

The herbivores in the forest don’t consume this low-growing invasive plant because they mistake it for a similarly shaped toxic plant in the forest. The invasive plant needs a lot of room to grow. It sprouts from its seeds much earlier than the native species. What effect can its growth have on the native herbivores’ food supply?
Answer:
It could grow at such an extrem erate that it could use up all natural resources that the native species needs to survive. thus breeding out all native species and becoming a invasive species. The native species the animals eat now does not exist and the animals that needed that food will decrease drastically in populus.

Part A Cut a 7-inch-diameter circle out of card stock. Draw a spiral on the circle as shown. Next, use the scissors to cut along the lines you drew starting on the outside and ending in the center. Use the hole punch or scissors to make a hole at the middle of the spiral and attach the thread with a knot. Tie the other end of the thread loosely around the center of the stick so you can suspend the spiral in the air. Fill the pot with 2 inches of water. Heat the water until it boils, and then turn off the heat source. Let the pot sit for 4 minutes. Holding the ends of the stick with the spiral attached, position the bottom of the spiral right above the top of the pot so it’s not touching the water. Describe what happens.
Answer:
the spiral stick wouldnt be wet because it isnt touching the water, so therefore the sprial stick wouldnt be hot because it isnt touching the water.
