the age of Rock in years is called its absolute age geologist find absolute age by measuring the amount of certain radioactive elements in the rock
The statement presented above is true.
Humans form gametes or reproductive cells in a process called gametogenesis.
During this process, a diploid cell (cell containing two sets of chromosomes) goes through a meiotic division, resulting in 4 haploid germ cells ( cells containing only one set of chromosomes) called gametes.
Answer:
d. Actively transported into the phloem
Explanation: Source is the place where sugar are been produced and are active transported to actively growing part of plants that requires it. The actively growing plants part that requires sugar are called sink.
Photosynthate the end products of photosynthesis is what is been loaded into the phloem through active transport and then moved to sink i.e plant part that requires the sugar through a process called translocation. The sink in plant includes the fruits, leaves for some vegetables,flowers for ornamental crop,too or tuber, rhizomes.
When the phloem cell is damage there is reduction in transport of photosynthate or accumulation in a particular part of plant.
Actively growing parts of plant have a high demand for sugar or sucrose than the old and weak parts of plants.
The largest population that an environment can support is called its carrying capacity.
Determining the carrying capacities for most organisms is fairly straightforward. For humans carrying capacity is much more complicated. The definition is expanded to include not degrading our cultural and social environments and not harming the physical environment in ways that would adversely affect future generations.
For populations which grow exponentially, growth starts out slowly, enters a rapid growth phase and then levels off when the carrying capacity for that species has been reached.
Answer:
It can give rise to a complete organism.
Explanation:
The zygote is the product of the sexual reproduction formed by the union of the sperm and ova. The zygote is the diploid in nature whereas the gametes are haploid in nature.
The fertilized egg has the ability to differentiate into the different cell type. The single cell can give rise to all the different organ of the body is known as totipotency. The fertilized egg has the ability to give rise to the whole organisms and shows totipotency.
Thus, the correct answer is option (2).
