Answer:
Other deposits may be from fossilized bone or bird droppings called guano. Weathering and erosion of rocks gradually releases phosphorus as phosphate ions which are soluble in water. Much of the phosphate eventually is washed into the water from erosion and leaching.
Explanation:
Every animal, plant and human needs the primary <u>physiological </u>needs of water, food and shelter provided by the abiotic system.
Organisms in the ecosystem are interdependent.<span> Ecosystem is encompassing all the life on earth in the physical environment that supports it. In addition, </span><span>an ecosystem involves both the biological (plants, animals, human beings) and non-biological (land, water, soil, and atmosphere) community which interacts as a system. More importantly, the living things are very dependent on the abiotic community since it cannot survive by itself. </span>
If Jerry wants to start a small business producing jelly made from marine algae he should select red algae for this purpose. Red algae is a major staple in some Asian and European cuisines.
Answer:
a) DNA fragments associated with histone proteins are all multiple in length (i.e., 260 bp, 520 bp, 780 bp, etc), thereby suggesting the presence of a pattern of organization in the chromatin
b) it suggests that each unit of organization (ie, each nucleosome) consists of 260 bp associated with chromatin proteins
Explanation:
The nucleosome is considered as the basic unit of chromatin. A nucleosome consists of approximately two turns of DNA wrapped around a core of eight histone proteins (i.e., a histone octamer). The histone octamer consists of two copies of each of the histones H2A, H2B, H3, and H4. Moreover, the nucleosomes are connected together by linker DNA sequences which vary between 10 and 100 bp in length.
