Blood types A and B are similar to each other because they both have antigen on red cells.
Blood type AB has both A and B antigens on red cells.
Hope this helped! :)
The journey of the food through the digestive system will actually digest the food. The rest will be given out as feces.
<h3><u>Explanation:</u></h3>
The digestive system actually consists of digestive tract and Digestive glands. The processes that are associated with digestive system is - ingestion, digestion, absorption, assimilation and egestion.
The food that is taken is first smashed and chewed into a rough bolus by mixing with saliva. The salivary amylase slightly digests the starch into dextrin.
Then the food is engulfed through the oesophagus into stomach. Inside stomach, the food is mixed with an enzyme pepsin and HCl. Pepsin digests the proteins into peptones and peptides. The food is converted into a bolus and transported into duodenum.
In duodenum, there are several enzymes from small intestine and pancreas breaks the fats into fatty acids, proteins into peptides and starch into carbohydrates like glucose. They are absorbed and the undigested substances are left over ad feces.

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.
In this zone, the intensity of light rapidly dissipates as depth increases. Such a minuscule amount of light penetrates beyond a depth of 200 meters that photosynthesis is no longer possible. The aphotic, or “midnight,” zone exists in depths below 1,000 meters (3,280 feet).
