The questions and the correct answers are as follows:
1. QUESTIONS:Which of the properties of soil has the greatest effect on plant and micro organism growth?
ANSWER: The correct answer is SOIL REACTION.
Soil has many properties, one of them is soil reaction. Soil reaction is one of the chemical properties of the soil and it refers to the degree of alkalinity or acidity of a soil. It is also called soil pH. Soil pH gives us the value of the concentration of hydrogen ion that is present in a particular soil. The pH ranges from 0 to 14 and a soil can be described as acidic, basic or neutral depending on its pH. The pH of a soil determines how soluble the soil ions will be and this in turn determines how well the plants and the microbes associated with the soil will grow.

2. QUESTION: Finding new sources of freshwater is an option for solving the world's water crisis. True or false.
ANSWER: The statement above is FALSE.
Finding new sources of freshwater is not going to solve the present water crisis, which the world is facing. The best that can be done is to finding a way of managing the water sources that we already have, so that they will be suitable for our use. This can be done through various means, such as: reducing water over-consumption, constructing waste water treatment plants and desalinating salt water.

Which type of fungus is shown in the diagram?

Answer from: Quest

you are certainly talking about this picture:

a: is the label of the white square, it is showing the replication fork, formed by helicase (d) ==> so it is the site of dna separation and replication

b: is a new dna brand that is following directly the replication fork, so it is continuous ==> built continuously from 5' to 3

c: dna polymerase cannot replicate dna on its own, it needs the of their proteins, and one of them plays the role of a clamp which fixes the dna with the dna template and increases the processivity of the enzyme. ==> stops polymerase from falling off the template.

d: is the enzyme responsible for forming the replication fork (helicase) ==> unwinds and separates dna into two strands

e: is the delayed strand, it is built in the opposite sense of the helicase, so dna will be built in fragments ==> built fragments from 5' to 3 joins

and finally f: is the enzyme that builds the new dna strand (dna polymerase) ==> adds nucleotides to make a new dna helix.

Parthenogenesis is a type of reproduction that does not require a mate. it’s rarely seen in birds and higher vertebrates. parthenogenesis involves the formation of a zygote. but this zygote is formed without fertilization. in parthenogenesis, in the absence of a male gamete, the ovum develops directly in the zygote.
