Answer: Carbohydrates usually function as energy storage or structural materials, and are composed of monosaccharides (simple sugars). All monosaccharides have three carbon atoms with a carbonyl group attached to one of the carbons, and hydroxyl groups attached to the remaining two. Monosaccharides are the primary fuel for metabolic processes, so we need the monosaccharides in carbohydrates to fuel our metabolic processes, making it an important part of our diet. If the subcomponents were joined by 1-6 linkages instead of 1-4 linkages, it wouldn't be called amylose, it would change to glycogen, making it less soluble. 

If the subcomponents of amylose were joined by 1-6 linkages instead of 1-4 linkages, the resulting molecule would have a branched structure instead of a linear one.

Amylose is a type of polysaccharide that is found in starch. It is made up of alpha glucose monomers that are joined together by alpha-1,4 glycosidic bonds.

If subcomponents were joined by 1-6 linkage if will result into a branched molecule named as Glycogen.

-The branched structure would make it easier for enzymes to break down the molecule, which could affect how quickly it is digested and how it is used for energy.

Therefore, the change in the linkage would result in a different structure and function of the molecule (glycogen) making it less soluble .

Answer:

Similar structures in eukaryotes with slight variations depending on their use.

Answer:

(a)The strength of natural fibers is very less as compared to synthetic fibers.  Natural fibers are heavy in weight.  Natural fibers can be damaged by moths and other insects.  These fibers are not wrinkle-free.  These fibers are not long lasting and hence not durable.

(b)  Cellulose is termed as polymer because it is made up of many monomer units.

(c) Rayon is first man- made fibre it is known as artificial silk because it have properties that are similar to silk.

(d) Rayon possesses many properties of natural fibers since it is a semi-synthetic fiber. Nylon is a synthetic fiber and has properties that are completely different from natural fibers. The key difference between rayon and nylon is their resistance to wrinkles and tears.

(e) Nylon has since become a popular choice, as it has excellent wind resistance, good elasticity, mildew resistance, and is comparatively cheaper. The material is also lightweight and dries quickly.

(f) When the piece of cotton is burnt then it burns completely and produces no odour or smell. When nylon is burnt, It completely burns and produces burning paper like odour. When nylon is burnt then the nylon is completely shrink and starts to melt first and then produces odour during the time of burning

Answer:

A. He should have controlled his speed.

B. He should have controlled his webs

Answer:

when a body covers equal distance in equal interval of time with a known direction, small the interval may be then velocity is said to be uniform velocity.

when an object covers unequal distance in a specified direction is said to be non-uniform velocity.

It produce zero acceleration as acceleration is defined as the rate of change of velocity per unit time. So, if the body exhibit uniform velocity,then the rate of change of velocity (dv=0) will be zero.

sentence 3

Explanation:

edge 2020

In sentence 3 'The Underground Railroad were a network of hiding places' a subject-verb agreement error is observed.

In a sentence when the subject of the sentence does not accept in number with the verb, the sentence misses subject-verb agreement.

In the given sentence 'The Underground Railroad were a network of hiding places'  the verb “were” is not matching the subject, it is a subject-verb agreement error.

There would be, 'was' is used as a verb in sentence three, correctly sets the subject-verb agreement. The subject of this sentence is the singular “one,” not the plural “Railroads.” This suggests the verb should also be singular.

Therefore, sentence three correctly depicts the subject-verb agreement error.

Answer:

Cell therapies would use stem cells, or cells grown from stem cells, to replace or rejuvenate damaged tissue. Scientists also want to use stem cells to understand disease and find drugs that might treat it. Embryonic stem cells could be used to make more specialized tissues that have been lost to disease and injury

The researchers prefer to use embryonic stem cell in medical research as Embryonic stem cells are able to differentiate into a wider range of call than adult stem cells.

A blastocyst, an early-stage pre-implantation embryo, is the source of embryonic stem cells, which are pluripotent stem cells. Four to five days after fertilization, human embryos reach the blastocyst stage.

The human blastocyst, an early stage of the developing embryo that lasts from the fourth to seventh day after fertilization, contains embryonic stem cells (ESCs) in its inner cell mass. In typical undeveloped turn of events, they vanish after the seventh day.

The ability to differentiate into cell types belonging to the three germ layers (ectoderm, endoderm, and mesoderm) is what is meant by the term "pluripotent." the three distinct types of tissue that are present during embryonic development and later combine to form the adult.

Answer: Biological, Phylogenetic

Explanation:

Answer:

Vasopressin, a hormon is secreted by pituitary gland which is response to dehydration , causes kidney to excrete less water.

The body's hormonal response to the dehydration is the action of vasopressin in the kidney. The vasopressin decrease the work of the kidney and it leads to decrease the amount of water secreted by the kidney to save water in the body.

Dehydration is a condition where there is less water present in the body. There are many reasons of dehydration, like drinking less water or diarrhea. All reactions of the body work by water. So loss of water severely affect the body.

The hormonal response to dehydration is the release of vasopressin by the pituitary gland of the body. The vasopressin saves water from the body to help body fighting with dehydration.  It makes the kidney to filter less water.

Thus, the activation of vasopressin in the kidney causes the body's hormonal reaction to dehydration. Vasopressin lessens the kidney's workload, which causes a reduction in the amount of water the kidney secretes to conserve the body's water supply.

Explanation:

The process of pollination is an example of mutualism. Thus, the correct option is C.

Mutualism may be defined as a +,+ interaction in which both species may be benefitted when living together.

During the process of pollination, the host plant will receive the service of insects to provoke the pollination successfully while in return insects get the food (nectar) and space to live on the plant's flower.

Therefore, the process of pollination is an example of mutualism. Thus, the correct option is C.

6CO2 + 6H2O → C6H12O6 + 6O2.

Explanation:

The process of photosynthesis is commonly written as: 6CO2 + 6H2O → C6H12O6 + 6O2. This means that the reactants, six carbon dioxide molecules and six water molecules, are converted by light energy captured by chlorophyll (implied by the arrow) into a sugar molecule and six oxygen molecules, the products.

Answer:

Photosynthesis is a physio-chemical process by which green plants use light energy to drive the synthesis of organic compounds. It is an enzyme regulated anabolic process.

Explanation:

Answer:

During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. ... This transforms the water into oxygen and the carbon dioxide into glucose. The plant then releases the oxygen back into the air, and stores energy within the glucose molecules.

The scientific method serves as a structured framework for conducting scientific investigations.

The scientific method involves a series of steps, starting with observation and formulation of a research question. Researchers then formulate hypotheses, educated guesses about the outcomes of their experiments.

These hypotheses are tested through carefully designed experiments, allowing for the collection of empirical data. The collected data is then analyzed to draw meaningful conclusions. The scientific method promotes objectivity, consistency, and reproducibility in research, enabling scientists to build upon existing knowledge and refine their understanding of the natural world.
