Name one or two diseases that affect each of these body systems:

Illusion [34]

Answer:

Symbiosis is a close relationship between two species in which at least one species benefits. Mutualism is a symbiotic relationship in which both species benefit. Commensalism is a symbiotic relationship in which one species benefits while the other species is not affected.

Marianne is comparing two animals: a fruit fly and a fruit bat. She asks, "Do a fruit fly and a fruit bat share a common ancesto

Sonja [21]

The answer is; YES

All organisms share one common ancestor in the beginning of life. Different species have branched at different times from common ancestors hence he evolutionary tree looks like tree called a cladogram. The nodes represent the common ancestry while branches depict divergence. Therefore even fruit flies and the fruit bats even though they do not belong to the same species shared a common ancestor at one time in history.

The trait for medium-sized leaves in iris is determined by the genetic condition PP'. Plants with large leaves are PP, whereas p

loris [4]

Answer:

See the answer below

Explanation:

Medium size leaves genotype = PP'

Large leaves genotype = PP

Small leaves genotype = P'P'

Red flower genotype = RR

Pink flower genotype = RR'

White flower genotype = R'R'

Two plants each with medium-sized leaves (PP') and pink flowers (RR') were crossed.

PP'RR' x PP'RR' (let PP' = Aa and RR' = Bb)

Progeny and expected phenotypes

1 PPRR - large leaves, red flower = 1/16 x 640 = 40 seedlings

2 PPRR' - large leaves, pink flower = 2/16 x 640 = 80 seedlings

2 PP'RR - medium leaves, red flower = 2/16 x 640 = 80 seedlings

4 PP'RR' - medium leaves, pink flower = 4/16 x 640 = 160 seedlings

1 PPR'R' - large leaves, white flower = 1/16 x 640 = 40 seedlings

2 PP'R'R' - medium leaves, white flower = 2/16 x 640 = 80 seedlings

1 P'P'RR - small leaves, red flower = 1/16 x 640 = 40 seedlings

2 P'P'RR' - small leaves, pink flower = 2/16 x 640 = 80 seedlings

1 P'P'R'R' = small leaves, white flower = 1/16 x 640 = 40 seedlings

The theory of endosymbiosis suggests that chloroplasts and mitochondria were once free-living prokaryotes, that were engulfed by

Drupady [299]

The question is incomplete. The rest of the question is : Which of these is not supported by the endosymbiosis theory concerning organelles?

A) contain DNA.

B) contain ribosomes.

C) are capable of living independently.

D) are surrounded by a double membrane.

Answer:

Option C) are capable of living independently is not supported by the endosymbiosis theory concerning organelles

Explanation:

The endosymbiosis theory proves that chloroplasts and mitochondria were prokaryotic cells before due to many reasons. Some of which are:

These organelles have their own separate DNA.
The separate DNA present in them is capable of making their own proteins.
They are membrane- bound organelles.

However, these organelles can now not live separately outside of the cell. This might be because of the evolutionary changes which occurred in these cells during the long period of time.
