Biology
1 answer:
sveta [45]3 years ago

Answer:

<u>Starch</u> is the storage form of glucose (energy) in plants and the glucose molecules are linked by alpha 1,4 glycosidic linkage.

<u>Cellulose </u>is a structural component of the plant cell wall and glucose molecules are linked by beta 1,4 glycosidic linkage.

<u>Glycogen</u> is the storage form of glucose (energy) in animals and glucose molecules are linked by alpha 1,6 glycosidic linkage.

Explanation:

All of these sugars are polysaccaride sugars containing large number of glucose subunits.

Starch is a polysaccharide extracted from agricultural raw materials. It contains amylose and amylopectin. Amylose is an un-branched chain polymer of D-glucose units while amylopectin is a branched chain polymer of D-glucose units.

Glycogen is the storage form of glucose in animals, It is stored in muscles and liver and it is a branched polysaccaride.

Cellulose is the storage form of glucose in plants and leaves.

boyakko [2]

Answer:

homologous

Explanation:

<em>Since the front legs of a cat and the arms of a human share a bone structure that suggests a common lineage, these structures are said to be homologous.</em>

Homologous organs are organs that share some similarities in different organisms but whose function differ in these organisms.

The organs are structurally similar but functionally different. Homologous organs represent one of the evidences scientists use to support evolution.

The front legs of cats and the arms of humans are functionally different, even though their structure is based on the same five digit plan.

In sexually reproducing multicellular organisms, the main functions of mitosis are _____. Check all that apply.
nasty-shy [4]

Answer:

b)repair/replacement of damaged cells growth and development

Explanation:

Mitosis is a process of cell division that has many purposes. In individuals of sexual reproduction such as humans, mitosis is responsible for multiplying cells during the embryonic development; through this process the zygote (unicellular) is transformed into a multicellular organism. Additionally, mitosis allows the formation of new cells for tissue growth and to replace worn out cells.

The cell division that allows the gamete production for reproduction is a different process called meiosis.

Answer:

How do nutrients move through an environment? What drives the movement of nutrients?

My answer 6b: Nutrients are often transported across the environment by migrating from the physical environment into living creatures and then being recycled back into the physical environment. For example, an animal could receive nutrition by eating plants. To stay alive, the animal uses the chemical energy gained from the food. When the animal dies, the nutrients in its body return to the soil and are re-absorbed by plants. The transport of nutrients in the ecosystem is driven by nutrient cycles.
