In which of the following ways does a fertilized egg differ from an unfertilized egg? A) A fertilized egg has more unpaired chro
mosomes than an unfertilized egg. B) A fertilized egg has chromosomes that will soon go through meiosis while an unfertilized egg's chromosomes have already divided. C) A fertilized egg has fewer chromosome mutations than an unfertilized egg. D) A fertilized egg has chromosomes from two parents while an unfertilized egg only has chromosomes from the mother.
Answer - D Gametes always have half the number of chromosomes compared to the somatic cells, hence an unfertilized egg would have half the chromosomes from the mother, and a fertilized egg will contain diploid number of chromosomes. Half of them from inherited from each of the two parents.
The fertilized egg has 46 chromosomes since it is fertilized by the sperm which makes 23 + 23= 46 so, it is fertilized by both parents. HINT: The sperm is produced in the uterus by the father. An unfertilized egg has 23 chromosomes since it is not fertilized by it's father. Therefore, it is only fertilized by it's mother since the mother produces the egg through the ovaries.
Plants (biosphere) draw water (hydrosphere) and nutrients from the soil (geosphere) and release water vapor into the atmosphere. Humans (biosphere) use farm machinery (manufactured from geosphere materials) to plow the fields, and the atmosphere brings precipitation (hydrosphere) to water the plants.
Carrying capacity is the limit to which a population can grow with the resources (food, water, oxygen, habitat space, etc.) are available to support them. Once they reach the maximum population that the environment can support, they reach their carrying capacity.
