Population density (in agriculture: standing stock and standing crop) is a measurement of population per unit area or unit volume; it is a quantity of type number density. It is frequently applied to living organisms, and most of the time to humans.

Answer:

Plants that adapted to the cooler conditions would survive and rapidly evolve into a new species.

Explanation:

The plants will react by evolving through natural selection.

The plant species that do not have the genes to adapt to the rapid change in climate would become extinct while those with adaptive genes will survive, reproduce, and contribute rapidly to the development of future generations.

In other words, natural selection selects for individuals with adaptive genes and ensures that such individuals reproduce more and give rise to future generations with the adaptive gene while individuals that are poorly adapted to the change in climate gradually fade off the population.

Hence, the plants that adapted to the cooler conditions would survive and rapidly evolve into new species.

Can someone help with the labels for this ?

JulsSmile [24]

Answer:

Refer to the attached image for correct labeling.

Explanation:

The diagram is of a plant cell and its organelles.
The nucleus houses the genetic material and controls all life processes.
A plant cell contains one large vacuole in the center that stores water and nutrients.
Chloroplast is the site for photosynthesis. It captures light and utilizes it and carbondioxide to produce glucose.
Mitochondria are called the power house of the cell. Through a process called cellular respiration, they break down the glucose produced in photosynthesis into energy compounds such as ATP as well as oxygen and water.
The endoplasmic reticulum is the site for protein sysnthesis. It contains two parts: the rough endoplasmic reticulum (RER) which contains ribosomes that synthesize proteins and the smooth endoplasmic reticulum (SER) which packages the proteins into transport vesicles.
The nucleus contains the nucleolus that is the site for ribosome assembly.
The cell membrane is a semi-permeable membrane that covers the cell and controls cellular transport.
The cell wall is a hard, outer covering that protects the cell and maintains its structure and shape.

Can you explain how more life-forms were able to create because of cyanobacteria PLEASE HELP

Ainat [17]

The cyanobacteria changed the composition of the earth’s atmosphere by evolving oxygen in what is referred to as the Great Oxygenation Event. This also allowed the ozone to be formed and block off most of the UV rays that are destructive to genetic material. Life was, therefore, also able to exist on land other than in water.
