Answer:
Plant-like protists produce almost one-half of the oxygen on the planet through photosynthesis. Other protists decompose and recycle nutrients that humans need to live. For example, medicines made from protists are used in treatment of high blood pressure, digestion problems, ulcers, and arthritis. Fungi are very important ecologically, because they are one of the most important decomposers in most ecosystems. They help to break down plant fibers such as dead leaves and wood and allow the nutrients to be released into the soil. Fungi are useful to humans because they have economic value.

Explanation:
In certain flowering plants, the flower contain more stamen than pistil to increase chances of pollination.
The stamen is the male reproductive part of a flower and the pistil is the female reproductive part of the flower.
More stamen means more pollen. By producing more stamen and therefore more pollen, the chances of pollen coming into contact with the pistil are much higher especially since pollination depends on either wind or insects.
However, not all flowering plants have this arrangement.
Answer:
- According to the cladogram what separates rabbits/primates from crocodiles is that the former have a divergence before the latter and are viviparous.
- The organism that is most closely related to rodents and rabbits in the cladogram is the primate.
Explanation:
The cladogram (see image) shows the evolutionary line that several animal species have followed. According to this, the following conclusions can be established:
- <em>Both primates and rabbits/rodents are mammals, with intrauterine development of their offspring, while crocodiles and birds are oviparous, which represents a </em><em><u>divergence in their evolution</u></em><em>.</em>
- <em>The species most related in the cladogram to rabbits / rodents is the primate, since they share several characteristics in common, such as being mammals, skin covered with hair and being viviparous.</em>
Characteristics such as these are what allow the classification of different animal species.
As materials move from higher to lower concentration diffusion is occurring.
has a whippy tail called a flagellum that allows it to move through the water. The euglena is different than other protozoans because it has chlorophyll in it, the substance that plants contain to make their own food. The euglena is then able to make its own food like a plant when it is in the sunlight.
