The correct answer is this: ALL CELLS ARE PRODUCED FROM EXISTING CELLS.
 Rudolf Virchows was a doctor and scientist of German origin. He was the first scientist to apply cell theory to mechanism of diseases in humans, this aspect of medicine is called pathological processes.  Through his research, he discovered that new cells are always produced from existing cells.

Which of the following describes the nervous system integrative function? A. responds to stimuli by gland secretion or muscle co
Verdich [7]

Answer:

B. analyzes sensory information, stores information, makes decisions

Explanation:

The receptors sense the changes or stimuli. The sensory neurons of the nervous system deliver this sensory information to the processing center, that is, to the central nervous system. The central nervous system serves to store the information and analyze it to determine the best suitable response. The ability of the nervous system to the store and process of sensory information to make the effector organs to exhibit the best response represents its integrative function.

Function in the cell cycle. Explain why interphase is important before mitosis begins.
Luda [366]

Answer:

During interphase, the cell copies its DNA in preparation for mitosis. Interphase is the 'daily living' or metabolic phase of the cell, in which the cell obtains nutrients and metabolizes them, grows, replicates its DNA, and conducts other "normal" cell functions. This phase was formerly called the resting phase.

Attached earlobes are recessive to free earlobes. What genotypic ratio is expected when an individual with attached earlobes mat
Marianna [84]

Answer:

C

Explanation:

This is a monohybrid cross between involving a gene coding for earlobe. The allele for free earlobe (F) is dominant over that of attached earlobe (f).

N.B: let F represent the gene involved.

A genotypic ratio is the ratio derived from the offsprings based on the actual genetic make-up and not based on their phenotypic appearance as in phenotypic ratio.

A homozygous individual is an individual having the same kind of alleles for a gene while a heterozygous individual is one that has two different alleles i.e. combination of the dominant and recessive allele.

The monohybrid cross is between an individual with attached earlobe (ff) i.e. homozygous recessive individual. (Note that, a recessive trait will only be expressed in a homozygous state) and a heterozygous free earlobeb individual (Ff). (See attached picture). Ff × ff

The resulting four offsprings will

be expected to have only two distinct genotypes i.e heterozygous (Ff) and homozygous recessive (ff) in an equal ratio i.e. 2:2 ~ 1:1
