it would be (D) because you cant see an atom without a microscope and a model is a larger model of the actual thing.
The correct answer is "either buyers or sellers of gasoline"
Explanation:
The best way to significatively reduce the use of fossil fuels is to tax on both sellers and consumers. Moreover, it also becomes necessary to promote policies associated with the use of alternative energy sources and to subsidize its use
Answer:Phaeophyta--Described as "hairy" in appearance produce alginic acid, which can be used as a thickening agent.
Rhodophyta ;are utilized commercially to produce carrageenan and can photosynthesize at depths greater than 10 meters
Chlorophyta;Considered the progenitor of land plants, have 18S rRNA sequences comparable to plants
Chrysophyta;The is a diverse group that includes the diatoms, a major component of phytoplankton
Explanation:algae are a diverse group of organisms with majority of them living in water and a few on land. They are green and contains chlorophyll.they also contains phycobillins pigments.
Chlorophyta are green algae that exist in water habitat an example is Chlamydomanas reinhardi.they have similar structures with higher plants such as chlorophyll, cellulose cell wall and stores food as starch.
The chrysophyta includes diatoms.diatoms have a cell wall composed of pectin and deposits of silica. They may occur in large deposit as diatomaceous earth.
Phaeophyta--are brown algae. An example is sea weed they are found in deeper ocean waters. Sea weed has a thallus which branches into a basal holdfast that aids attachment to rocks.their blade allows the plant to float
Rhodophyta are algae which are sometimes Unicellular in form they have a characteristic red color due to the presence of phycoerythrin along with phycocyanin, chlorophyll.they are used as source of algar for microorganism culture.
Answer:
Thousands of species is an example of biodiversity.
<u>Explanation:
</u>
<em>Biodiversity is the short term for biological diversity which was coined by E.O. Wilson</em>. <em>Biodiversity refers to all the species of plants (flora) and animal Kingdom (fauna) present on the Earth.</em> It covers different types of ecosystems present in a well-defined area whether it be terrestrial or aquatic and the genetic variability within a species.
The variety of crops and livestock present on Earth have played a great role in human development. Without them, life would not be possible. That’s why it is our moral duty to conserve our biodiversity. If we preserve it for our future generations, we will survive. If they are overused or misused, the entire food chain would perish.
Blood flows to the brain through the internal carotid and vertebral arteries and away from the brain through the internal jugular vein. The internal carotid artery supplies the brain, while the external carotid nourishes other portions of the head, such as the face, skull, scalp and the meninges. The vertebral arteries provide supply to the upper spinal cord, brainstem, cerebellum, and the posterior part of the brain.
