Toucans disperse seeds of key forest species such as juçara palms by eating the fruit and defecating the seeds in new locations, sometimes more than a kilometer away. If there are no toucans, is the genetic diversity of palms likely to increase or decrease within forest fragments (and why)?

The genetic diversity of palm will totally decrease as a result of absence of Toucans dispersal of palms seeds which would not allow the seeds to be randomly grown anywhere. Dispersal has great impact on biodiversity of fruits because it enables the distribution of seeds to be grown everywhere

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.

What are limitations to radiometric dating?

Anon25 [30]

Radiometric dating depends on radiation from carbon atoms which means only carbon based things can be dated. And life is based on carbon so basically only living things can be dated.
