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:
physical, cognitive, socio-emotional
Explanation:
The complete question is as follows:
According to the text, the interaction of what three developmental domains shapes human development?
Select one:
a. social, physical, moral
b. mental, physical, environmental
c. physical, cognitive, socio-emotional
d. environmental, genetic, perceptual
- The term domain describes the specific aspects of the change and growth that takes place in relation to the human development.
- The three main developmental domains that shapes human development are :physical, cognitive and socio-emotional domains.
- The physical domain includes the physical changes and growth that takes place in a human body. It also includes the development of the motor skills and the use of senses.
- The cognitive domain covers the aspect of development creativity and intellectual skills. It includes various factors such as memory, attention, planning, thought processing and accomplishing goals.
- Socio-emotional domain includes the ability to deal with emotions and udnerstanding others emotions. This is a phase of developing attachments and interaction skills. During this phase the cooperative nature, empathatic nature and morality of an individual develops.
Answer:
a. Biomagnification
Explanation:
Biomagnification is the name given to the progressive accumulation of substances from one trophic level to another along a food chain. Thus, the substance will have its highest concentration in individuals who occupy trophic levels furthest from producers.
For biomagnification to occur, substances must be fat soluble (lipid soluble) and thus adhere to living tissues. Another feature of substances that undergo biomagnification is that they are generally not biodegradable or metabolized by the body.
The phenomenon is quite common with heavy metals (lead; mercury) and certain chlorinated and aromatic organic compounds with higher molecular mass, such as the insecticide DDT.
