Answer:
Advantages and Disadvantages of Vegetative Propagation
ADVANTAGES
Faster and more certain method of propagation.
New individuals produced have exactly identical qualities as their parents. This preserves the characteristics of food and flower crops.
Can be used to reproduce plants that do not have viable seeds.
The flowers produced are of a superior quality.
Certain desirable characteristics present in the fruit can be maintained.
DISADVANTAGES
Does not produce new varieties
Leads to over crowding
Very little dispersal

Answer:
In the case of seeing a ball and kicking it can be expressed in the actions of the nervous system as follows:
Part 1. Eyes see the ball and send signals with the help of sensory neurons that carry this message to the spinal cord.
PArt 2. The spinal cord processes the information and sends an "impulse" of kicking the ball that will transfer to motor neurons that transfer it to the brain and then muscles.
Sensory neurons --> spinal cord --> motor neurons --> brain---->leg muscles
b. The rock cycle is a biogeochemical cycle.
c. Biogeochemical cycles are an important part of the Earth system.
d. Carbon, nitrogen, and oxygen cycles are biogeochemical cycles.
c. Biogeochemical cycles are an important part of the Earth's system.
The biogeochemical cycle is any of the herbalpathways via which critical factors of livingmatter are circulated. The time period biogeochemical is a contraction that refers to the attention of the organic, geological, and chemical factors of each cycle. The generalized carbon cycle.

A
All cells contain ribosomes that conduct protein synthesis.
B
Cells contain genetic information in the form of DNA.
If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their
own.
If isolated from a plant cell, a chloroplast can survive and reproduce on its own.
Answer:
C. If isolated from a eukaryotic cell, mitochondria can no longer survive and reproduce on their own.
Explanation:
The endosymbiotic theory proposes that early eukaryotic cells evolved from endosymbiotic interactions among prokaryotic cells. This theory states that mitochondria and chloroplasts were once primitive bacterial cells that were ingested by large anaerobic prokaryotic cells, and then these cells benefited from living and working together. The most important lines of evidence that support this theory are that mitochondria and chloroplasts contain their own genetic material (circular DNA) and their own protein biosynthesis machinery (ribosomes).
The statement supporting the endosymbiotic theory claims chloroplasts can survive and reproduce on their own when isolated from a plant cell. This suggests these organelles, once independent prokaryotic cells, retain certain autonomous features despite integration into the eukaryotic cells.
The endosymbiotic theory proposes that certain organelles in eukaryotic cells, such as mitochondria and chloroplasts, originated as independent prokaryotic cells that were engulfed by a host cell. This event allowed a symbiotic relationship to develop, which subsequently led to the development of eukaryotic cells. The option that best supports this theory is: 'If isolated from a plant cell, a chloroplast can survive and reproduce on its own.'
This statement suggests that chloroplasts, like the bacteria from which they evolved, maintain some ability to live independently. Yet, although they contain their own DNA and ribosomes (symbols of their independent past), they are no longer 'free-living'. Similarly, mitochondria are also likely to have been independent entities because they too contain their own DNA and ribosomes. However, having been integrated into the host cell, they can no longer survive on their own, contrary to what might be inferred from the third option. The first and second options simply represent characteristics of all cells and provide no specific support for the endosymbiotic theory.
