A model of the theory of endosymbiosis is shown here. It is an explanation for the presence of chloroplasts and mitochondria as

organelles that might have had an origin as free-living prokaryotic cells at one time. Evaluate each staternent below and select the ones that accurately describe how evolution and endosymbiosis gave rise to life on Earth as we know it today.

A germ cell and zygote represents the biological level of organization. __________
kompoz [17]

Answer: Cell

Explanation:

The cell is the structural and functional unit of life. It is the the most basic level. A life starts from a single cell.

When a male and female gamete(germ cell) fuse together they form zygote. Firstly it is a single cell surviving inside the mother's womb.

Then differentiation takes place and the cell keeps on dividing to form different tissue layers and then organs form which makes a complete baby. Hence, zygote and germ cell are cellular level of organization.

(c) find the longest interval during which no tree-cutting samples occurred. what is the first year that no tree-cutting samples
MaRussiya [10]

Answer:

Longest interval during which no tree-cutting sample occurred: 9 years (1203 AD - 1212 AD)

First year in that interval: 1203 AD

Explanation:

Lets complete the question first.

Q) A study uses tree rings to determine the year in which a tree was cut. The data is shown in the leaf and stem diagram in the ATTACHMENT.

The three digits number in the left column represents centuries and decades AD. The numbers on the right represents the years.

For example, consider the first input in the diagram

119 | 5   6

which means it represents 2 samples.

1195 AD, 1196 AD.

The longest interval with no tree-cutting samples is found from 1203 AD to 1212 AD.

Veseljchak [2.6K]

The term myoparesis is used to describe the weakness or slight paralysis of the muscles. The myoparesis can begin in a person suddenly or it might progress with gradual weakness of the muscles. The affected individual may suffer from weakness of the muscles with incomplete paralysis along with experiencing pain and spasms in the affected muscles. The causes for the development of myoparesis includes stroke, cerebral palsy, multiple sclerosis, and spinal cord injury.

Hence, the answer is 'weakness or slight muscular paralysis'.
