Answer:
The correct answer is option (d) "both b and c".
Explanation:
Experimental model organisms used in scientific investigations have to fulfill certain criteria in order to be useful in the laboratory. Two of the desired characteristics are being able to reproduce quickly and with enough number of offspring in order to study genetic behaviors. <em>Arabidopsis thaliana</em> characteristics of being able to reproduce in 8–10 weeks and producing thousands of offspring per plant (because it can produce thousands of seeds) makes it a model flowering plant for experimental studies.
It cannot be a bacteria because bacteria is made up of one cells, as it is a unicellular organism. Secondly, chlorophyll is the chemical that is in plants that makes the leaves on said plant green. So that makes the correct answer plants and proves why C.Bacteria is wrong.
Answer:
(E) Soil disturbances can result in fewer blooms, and hence lower seed production.
Explanation:
According to the experiment, the eight control plots were left undisturbed, that is, their soil was not exposed to any disturbance. On the other hand, the soil of the experimental plots was disturbed during the removal of dandelion species. This disturbance might have resulted in reduced flowering in the experimental plots due to many reasons such as removal of fertile topsoil.
The reduced flowering in these plots might have caused lower seed set. The control groups had undisturbed soil which in turn favored more flowering and seed production than in the experimental groups.
Answer: 1) DNA ( deoxyribonucleic acid) is considered as the genetic material of living organisms ( that is passed from parents to next generation). It determines the structure of protein that carry out essential function of life.
- For this, DNA possesses instructions in the form of specific nucleotide sequences. First it undergoes transcription, in which genetic information from DNA is passed to mRNA ( messenger RNA), which is finally converted to specific protein through translation.
2) The importance of DNA determining proteins is that the proteins, which are formed, corresponds to specific cellular activities ( such as digestion of proteins, fats, carbohydrates) as well as the characteristics/ traits ( like color of skin, color of eyes) of the organism.
In this way, traits are passed from parents to their offspring through genetic material.
Answer:
Earth's rotation is the main reason for the Coriolis effect. The effect deflects anything that flies or flows over a long distance above the ground, proportionate to Earth's spin direction. Even storms can be a result of the rotation; hence, they do not form similarly everywhere on Earth.
