No, the number of chromosomes does not
indicate how complex an organism is.
Chromosomes can be refers to as strand of DNA that is encoded
with genes. Also, they are DNA molecules with all the genetic materials or part
of genetic materials of an organism. However, the number of
genes and genome size present in an organism reveal little about organism complexity.
The shape of a protein allows it to perform its particular job.
Answer:
c. In mines or confined places, where oxygen levels have been depleted, ventilation may occur.
Explanation:
Environments classified as “confined space” are hazardous for several reasons, but one of the main ones is the low oxygen concentration. Normally atmospheric air contains a 21% concentration of oxygen that is necessary for the maintenance of human life. Some confined spaces have this concentration of less than 21% oxygen, which can be very harmful to human life and lead to death.
Low oxygen concentration can be masked by ventilation in confined places. This is because in confined places oxygen levels may be low, but ventilation may continue despite inadequate oxygenation.
First of all D does not make sense so you can roll that out right away yeah answer would be B
Answer:
Zygote, fertilized egg cell that results from the union of a female gamete (egg, or ovum) with a male gamete (sperm). In the embryonic development of humans and other animals, the zygote stage is brief and is followed by cleavage, when the single cell becomes subdivided into smaller cells.
