Raw green plants cant be digested by us humans because they contain cellulose, which we can't digest.

We basicly can't digest them as it has cellulose and we can't digest cellulose .acc. to me in olden days early men used to survive with raw green plants because the cellulose is digested by our appendix  but slowly as  we stopped eating raw green plants the appendix lost it function tooo. so  we should always eat a  selective plant like lettuce

Consider the diagram. mc002-1.jpg Which process is represented? nondisjunction translocation inversion insertion
sladkih [1.3K]

If this is the picture you are talking about, the right answer is non-disjunction

Non-disjunction is the non-separation of homologous chromosomes at the time of cell division which results in the formation of ova or spermatozoa leading to an abnormality in the number of chromosomes of the egg thus fertilized by the spermatozoa.

The fertilized egg consists of either a single chromosome, what is called monosomy, or, conversely, three chromosomes, this is called trisomy. While naturally, the fertilized egg has a single pair of chromosomes.

Which of the following is an example of catabolism? A. The synthesis of the cell membrane from precursor molecules B. The oxidat
Shtirlitz [24]

Answer:

The correct answer is option B. the oxidation of glucose in the cytoplasm and mitochondria.

Explanation:

The catabolism is the reaction or process that involves breakdown of the larger molecules into smaller molecules. This is the one of the metabolic reaction. Such reactions releases energy.

Oxidation of glucose is a catabolic reaction that involves spliting of glucose into water and oxygen in the respiration.

Thus, the correct answer is option B. the oxidation of glucose in the cytoplasm and mitochondria.

Which of the following statements concerning carbohydrates associated with the plasma membrane is correct? (eText Concept 7.1)
Ksju [112]

Answer:

The correct answer is : * Membrane carbohydrates function primarily in cell-cell recognition.

Explanation:

The carbohydrates (poly or oligosaccharides) associated with the plasma membrane, are covalently bound to it (to proteins or lipids). They are found in the outer part of the plasma membrane forming the glycocalix. Its main functions are:

-Cell recognition

-Support to the membrane.

If you measure the rate of respiration of plant root hair cells, would you expect it to be the same as, more than, or less than
DaniilM [7]

Answer:

The process of respiration in plants involves using the sugars produced during photosynthesis plus oxygen to produce energy for plant growth. In many ways, respiration is the opposite of photosynthesis. In the natural environment, plants produce their own food to survive.As with photosynthesis, plants get oxygen from the air through the stomata. Respiration takes place in the mitochondria of the cell in the presence of oxygen, which is called "aerobic respiration".

In plants, there are two types of respiration: dark respiration and photo respiration. The first kind occurs in the presence or absence of light, while the second occurs exclusively in the presence of light.<em>Plant respiration occurs 24 hours per day</em>, but <em>night respiration is more evident since the photosynthesis process ceases.</em> During the night, it is very important that the <em>temperature is cooler than during the day</em> because plants can experience stress. Imagine a runner in a marathon.

roots respire too!

One of the functions of the substrate is <em>to serve as a site for air exchange between the root zone and atmosphere</em>. In other words, <em>roots breathe oxygen like we do</em>. Different plants have different oxygen requirements for their root systems.

For example,

<em><u>the root system of a poinsettia requires a lot of oxygen, so it is best to use a substrate with high air porosity, while hostas can live well in a substrate with a high water holding capacity. </u></em>
