Question

1) Cells are _. (1pts) only found in pairs, because single cells cannot exist independently limited in size to 200 and 500 micrometers in diameter characteristic of eukaryotes but not prokaryotes characteristic of eukaryotes and prokaryotes 2) In comparison to eukaryotes, prokaryotes_ pts) are more structurally complex are larger are smaller do not have membranes 3) A localized group of organisms that belong to the same species is called a pts) community population ecosystem family 4) When a person gets dehydrated while exercising on a hot day, their pituitary gland releases ADH, a hormone that signals the kidneys to retain more water. This is an example of: (pts) positive feedback negative feedback chemical cycling emergent properties 5) Prokaryotes are classified as belonging to two different domains. What are the domains? (Ipts) Bacteria and Eukarya Archaea and Monera Bacteria and Protista Bacteria and Archaea

Answer 1

1.The cells contains 23 pairs of chromosomes in the cell

The size of the cell vary widely ranging from 0.1 to 5.0 micrometer in size.

The cells are both prokaryotic and eukaryotic in nature

Ans:characteristics of eukaryotes and prokaryotes

2.The eukaryotes are the larger complex cells whereas the prokaryotes are smaller in size and simple

Ans:are smaller

3.A localised group of organism that belong to a the same species is termed to be population

Ecosystem is the mixture of the environment with living and non living systems

Family refers to group of members from a common ancestors

Community refers to the people living in a particular area

Ans:population

4.Positive feedback mechanism gives a good result for instance contraction during labour leads to child birth

Negative feedback stimulation can lead to opposite effect .here the body losses fluid to counter balance and retain the fluid anti diuretic hormone are released

The repeatation of the chemical compounds are called as chemical cycling

The complex system or the system components are termed to be emergent properties

Ans:negative feedback
