The carbon cycle is the biogeochemical cycle by which carbon is exchanged among the biosphere, pedosphere, geosphere, hydrosphere, and atmosphere of the Earth. Carbon is the main component of biological compounds as well as a major component of many minerals such as limestone.
Answer:
The correct statements are:
- Meiosis results in four haploid daughter cells.
- During meiosis, the 2N mother cells produce N daughter cells.
- In both processes, DNA replication must occur.
- Mitosis is responsible for genetic continuity; in higher organisms, it is essential for growth and repair.
Mitosis is a type of cell division in which a parent cell is divided into two identical daughter cells. Each daughter cell contains identical genetic material as that of the parent cell.
It plays important role in growth and repair of cells and tissues in multi-cellular organisms.
Meiosis is a type of cell division in which a parent cell is divided to produce four daughter cells. Each daughter cell contains exactly half the genetic material (chromosomes) as that of parent cells
It plays important role in the production of gametes (eggs and sperms) in sexually reproducing organisms.
Before either cell division, the DNA is replicated in the S or synthesis phase of the cell cycle.
Answer:
An example of abiotic factor include temperature, light and water. A seasonal
variation temp and precipitation will have a great impact on the population in the ecosystem
A new born has soft spot on he top of its head. This is called as fontanelle and is diamond in shape present on the top of the head of the baby.
Babies skull is very soft and can be very easily moulded, to help them squeeze through the birth canal at the time of delivery.
Moulding is done in the skull of the babies as it is most largest part of the body during the time of delivery.
As soon as the skull and bones of the baby meet and fuse they become hard gradually.
The answer is C. Maybe im not sure
