Monosaccharides are the monomer of which organic
compound?

Answers

Monosaccharides are the monomer of organic compounds called polysaccharides (carbohydrate).

WHAT ARE MONOSACCHARIDES:

Monosaccharides are simple compounds that contain one unit of sugar (saccharide). They are monomeric units of larger organic compounds called POLYSACCHARIDES, which are complex carbohydrates.

Monosaccharides cannot be further broken down as they are the simplest form of carbohydrate molecules.

Examples of monosaccharides, also called simple sugars are glucose, fructose, galactose etc. and they are monomers of polysaccharide molecules like starch, cellulose etc.

Hence, monosaccharides are the monomer of organic compounds called polysaccharides (carbohydrate).

What will most likely happen if all the chloroplasts are removed from a plant cell?

Answers

In the process of photosynthesis sunlight is absorbed by the chloroplasts to make sugar. Therefore, if chloroplast is taken out of the cell, the green plant will not be able to carry out the process of photosynthesis which means the plant will die.

What are Meristem cells?

Meristem cells are totipotent meaning they can differentiate to any type of plant cells. Therefore they can produce a variety of plant type depending on epigenetic. However, tissue culture is derived from already differentiated cells. These cells are already determined and can only produce cell type of that plant from which they were derived.

Gene therapy is a method of using genetic material to treat or prevent certain diseases. A common method researchers have found to accomplish this is with vectors. Vectors are essentially vehicles designed to deliver therapeutic genetic material, such as functional genes, directly to cells. A vector-valued function, also called a vector function, is a mathematical function of one or more variables whose extent is a multidimensional vector or a set of infinite-dimensional vectors.

Explanation:

Viruses are not made out of cells. A single virus particle is known as a virion, and is made up of a set of genes bundled within a protective protein shell called a capsid. Certain virus strains will have an extra membrane (lipid bilayer) surrounding it called an envelope.

Answer:

In the Cori cycle, when glucose is degraded by glycolysis to lactate in muscle, the lactate is excreted into the blood and returns to the liver.

Answers

Answer:

The correct answer is -

1. c. both

2. b. gluconeogenesis

3. d. neither

4. b. gluconeogenesis

5. a. glycolysis

6. c. both

7. a. glycolysis

8. d. neither

Explanation:

Gluconeogenesis is the formation or synthesis of glucose while glycolysis is the conversion of glucose into pyruvate. Gluconeogenesis requires an enzyme for a non-reversal reaction which is not required in glycolysis.

Glyceraldehyde 3-phosphate dehydrogenase is an enzyme present in glycolysis that converts glyceraldehyde 3-phosphate to 1,3-bisphosphoglycerate. It is a reversible reaction, this enzyme also present during gluconeogenesis converts 1,3-bisphosphoglycerate to glyceraldehyde 3-phosphate.

Glucose 6-phosphate to glucose during gluconeogenesis by glucose-6-phosphatase. Alcohol dehydrogenase is used for the conversion of ethanol into acetaldehyde and neither present in glyconeogenesis nor glycolysis. Oxaloacetate converts to phosphoenol pyruvate during gluconeogenesis by Phosphoenol pyruvate carboxykinase.

Fructose 6-phosphate changes into fructose 1,6-bisphosphate by Phosphofructokinase-1 during glycolysis.

Phosphoglycerate mutase is present in both pathways during glycolysis and during gluconeogenesis. This enzyme converts 3-phosphoglycerate to 2-phosphoglycerate and also converts 2-phosphoglycerate to 3-phosphoglycerate in glycolysis and gluconeogenesis respectively.

Hexokinase converts glucose to glucose 6-phosphate during glycolysis. However, Pyruvate dehydrogenase neither present in glycolysis nor gluconeogenesis.

The statement "carrying capacity can vary depending on environmental conditions" is true. Carry capacity is defined as the maximum population size of a species that an environment can sustain indefinitely. It is also defined as the environment's maximal load of a species. Factors that impact on the carrying capacity of a species are the availability of food and water, raw materials to build shelter, the environment's ability to process waste products, as well as the species' ability to reproduce.

2. When the heat of the air increases the density of the air decreases.

3. The air above the ocean will, therefore, be warmer and of low pressure than that over land which will be cooler and of relatively higher pressure. Winds will, therefore, blow seawards because winds blow from high to low-pressure systems.

Why do scientists think that all modern plants,
animals, and fungi can be traced to protist
ancestors?

Answers

Answer: Scientists think that all modern plants, animals, and fungi can be trace to protist ancestors because the protists is the root of all eukaryotic diversity. yw.

Scientists think that all modern plants, animals, and fungi can be trace to protist ancestors because the protists is the root of all eukaryotic diversity. ... The function that do cilia and flagella in protists carry out is movement. The first multicellular animals presumably evolved from colonial protists (most likely choanoflagellates), and within the colonies, cells progressively differentiated from one another, acquiring specific functional characteristics. It may sound like a bit of a stretch, but in fact such a phenomenon can be observed in colonies of extant unicellular organisms, both prokaryotes and eukaryotes, where some cells of the colony can become differentiated under particular environmental conditions. We can speculate that early in the history of animals some differentiation genetic programs evolved, got stabilized, and became inheritable from one generation to the next. Once different populations of cells were established in the colony, the door was opened to further specialization. Specialized cells were not initially grouped in organs but were more like regionalized populations or layers of cells, as we see in sponges, and morphogenesis progressively evolved

Punnett squares provide an easy way to predict the possible genotypes for an offspring, but it is not practical to perform a Punnett square analysis on all possible combinations of all members of a population to predict what the population might look like in the future.

a. True
b. False

Answers

Answer:

True

Explanation:

There are certain limitations associated with the Punnett Squares. They are not useful in case of complex genetic inheritance such as linkage between two genes. In case of linkages it becomes difficult to estimate the distribution of genotypes and phenotypes. For example in case of  Nail-patella Syndrome and gene associated with blood group two genes lie on the same chromosome in close vicinity and hence there are high chances of inheritance of these traits in the offspring from the parent thereby causing  random distribution of the two traits. This random distribution cannot be captured through punnet square.  

The same problem is associated in case where a single gene is determined by multiple genes with graded effects of each gene.
