Renewable energy refers to the provision of energy via renewable resources which are naturally replenished fast enough as being used. it includes e.g. sunlight, wind, biomass, rain, tides, waves and geothermal heat.
Answer:
C) Practicing good scientific method and practices.
Explanation:
The text states, "repeating the experiment multiple times," as well as other preparations that a good scientist uses.
Doing something multiple times over is a good sign of a good scientific method.
Taking careful measurements, having several researchers run the same experiment, and only testing one variable at a time are all good practices that a scientist should use.

Answer:
a) i) Xylem
ii) Upper epidermis
iii) Stoma
iv) Chroloplast
v) Palisade cell layer
b) By a waxy layer on the cuticle of the leaf
Explanation:
The plant's leaves have a large surface area that is capable of absorbing sunlight. The plant's waxy layer in the surface of the leaf protects it from the loss of water, as well as of diseases caused by the entry of microorganisms. The palisade cell's surface is a single layer of cells underneath the upper epidermis that is adapted to absorb light energy.
The waxy layer is a primary physical barrier composed of insoluble polymers and lipids whose function is to protect the leaves against the entry of harmful organisms including virus, bacteria and fungus. Moreover, the plant's waxy cuticle is also a barrier that prevents the loss of water and solutes.
Answer:
The carbon dioxide is one of the green house gases and mainly responsible for the increase of the earth's temperature. The plants uses the carbon dioxide for the photosynthesis process.
The plants that are exposed to the normal carbon dioxide can be used as a control in this experiment. Then the scientists will notice that if the amount of carbon dioxide is increased, does it show any positive or negative effects in the experiment.
Yes, but only if the chromosomes are paired in the right ways. tetrad development in late prophase.
<h3>How does DNA function? Why does it matter?</h3>
The biological instructions that give each species its distinctiveness are found in a substance known as deoxyribonucleic acid (DNA). Adult organisms reproduce by transmitting their DNA and the genetic information it carries to their progeny.
<h3>What is the purpose of a person's DNA?</h3>
Genes, which are a component of DNA, are the building blocks of all living organisms. DNA's capacity for recurrent self-replication is its most significant property. DNA must be replicated in order to create new cells, convey genetic information from one generation to the next, and act as a code for the RNA (ribonucleic acid) needed to make proteins.
