The extinction of a species would negatively affect human society because we may rely on that species for resources, or other species that interact with the extinct species may begin to decline, and those species could be essential to human survival.

Which linkages would you expect to find at a branch point in glycogen or amylopectin?
shusha [124]

Answer:

α-1,6-glycosidic linkage.

Explanation:

The carbohydrates are the polymers made of the sugars and bonded together through the glycosisdic bonds. The monosaccharides are the simplest unit of the carbohydrates.

The glycogen and amylopectin share similar structural features. Both have α-1,4-glycosidic linkage in their linear structure. The branching has been introduced in the glycogen and amylopectin structure through the α-1,6-glycosidic linkage.

Thus, the answer is α-1,6-glycosidic linkage.

Mo says it was the environment that made them who they are; Jasper says it was because of genetics. Which is it? Construct an ex
bija089 [108]

Answer:

It's the nature vs nurture situation. While the genetics of a person does control the physical traits he/she may develop, the environment also has a major role to play here. For instance, the person may have the genes for developing a tall height. If, however, that person is not provided with the right kind of nutrition and the right time, it is very likely that he/she will not grow as tall as they had the potential for. Similar explanation for non-physical traits.

This is not an 'either/or' type of argument. Genetics and the environment have a collective impact in shaping the person into who they are and while the balance may shift to one side or the other in certain cases, it does not cancel out or negate the other's effect.

Hope that answers the question, have a great day!

What is cell biology​
Anna [14]

Answer:

Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function and behavior of cells. Cell biology encompasses both prokaryotic and eukaryotic cells and can be divided into many sub-topics which may include the study of cell metabolism, cell communication, cell cycle, biochemistry, and cell composition. The study of cells is performed using several techniques such as cell culture, various types of microscopy, and cell fractionation. These have allowed for and are currently being used for discoveries and research pertaining to how cells function, ultimately giving insight into understanding larger organisms. Knowing the components of cells and how cells work is fundamental to all biological sciences while also being essential for research in biomedical fields such as cancer, and other diseases. Research in cell biology is interconnected to other fields such as genetics, molecular genetics, biochemistry, molecular biology, medical microbiology, immunology, and cytochemistry.

Kaylis [27]

Answer:

1. in animal cell and 3. in plant cell In animals mitochondria transforms energy and chloroplast in plant cell  absorb energy from sun light and turns water and carbon dioxide into glucose

Explanation:

1. Mitochondria: It is the powerhouses of a cell oval in shape found in eukaryotic cell.Its a site of cellular respiration. It converts glucose in chemical energy known as ATP (Adenosine triphosphate). ATP provides energy to carry out cellular function by breaking high energy bond.Mitochondria are abundant in cells requires energy to perform functions such as muscle and liver cells.

2. Chloroplast: In plants and algae chloroplast is a site of photosynthesis,it contains a pigment chlorophyll which captures energy from sunlight and turn water and carbon dioxide into glucose as food of plants.
