The process of linking monosaccharides to become polysaccharides is called __________, while breaking down polysaccharides, like glycogen, occurs during a process called __________.A: hydrolysis; dehydration synthesis
B: dehydration synthesis; hydrolysis
C: is crossed off
D: hydrolysis; glycolysis

Answers

The right option is B: dehydration synthesis; hydrolysis

The process of linking monosaccharides to become polysaccharides is called dehydration synthesis, while breaking down polysaccharides, like glycogen, occurs during a process called hydrolysis.

Dehydration synthesis is the process of linking two smaller molecules, or compounds, together to form a larger molecule following the loss of a water molecule.

Hydrolysis is the process of using water to break down a molecule such as carbohydrate into its component sugar molecules.


dehydration synthesis (releasing water to make covalent bonds); hydrolysis (using water to break covalent bonds)

.What does a reviewer do during peer-review?

Answers

Answer:

Explanation:

A peer review is a process of analysis of the research product by the person other than the one who has conducted the research. Such a person exhibit knowledge of the subject or topic in which the research has been conducted. The reviewer reads the written document related to the research, rectifies the mistakes and gives opinion for the betterment of the research outcome.

Which molecule in the chloroplast of a plant cell first captures light energy from sunlight? A. glucose B. carbon dioxide C.chlorophyll D. adenosine triphosphate

Answers

The molecule called chlorophyll which is present in the chloroplast of the plant cell captures the sunlight first. Thus, the answer is letter C. This molecule is responsible for the green color of leaves. This absorbs sunlight to use its energy in synthesizing carbohydrates. 
The molecule in the chloroplast of a plane cell that first captures light energy from sunlight is C. Chlorophyll.

The curved paths of global winds and surface currents are caused bya. the revolution of the Earth.
c. warm air near the equator.
b. the Coriolis effect.
d. continental deflection.

Answers

Answer:

The correct answer is option B, The coriolis effect  

Explanation:

The coriolis effect  describe the pattern followed by an object travelling around the earth. This effect is guided by the rotation of earth. Large air currents appear to bend in the right direction in northern hemisphere while the coriolis effect produces reverse condition in the southern hemisphere where air currents bend to the left  

The impact of the Coriolis effect is dependent on velocity of Earth and the velocity of the object and also on the  fluid being deflected by the Coriolis effect

Higher Coriolis effect  are seen when the speed is high or long distances are traversed.  

In the 1950s, when watson and crick were working on their model of dna, which concepts were well accepted by the scientific community?

Answers

Watson and Crick describe structure of DNA 1953 Photo: Model of DNA molecule In the late nineteenth century, a German biochemist found the nucleic acids, long-chain polymers of nucleotides, were made up of sugar, phosphoric acid, and several nitrogen-containing bases. In 1950, biochemist Erwin Chargaff found that the arrangement of nitrogen bases in DNA varied widely, but the amount of certain bases always occurred in a one-to-one ratio. 
Watson and Crick took a crucial conceptual step, suggesting the molecule was made of two chains of nucleotides, each in a helix as Franklin had found, but one going up and the other going down. 
Watson and Crick showed that each strand of the DNA molecule was a template for the other. 

In the 1950s, Both Watson and Crick were working on the composition of DNA, that is, the molecule that comprises the hereditary information for cells. The discovery of the double-helix, and the twisted ladder composition of DNA, by Watson and Crick, signified a landmark in the field of science and paved the path for the origination of modern molecular biology.  

However, when Watson and Crick were working on DNA model, some of the concepts were well accepted by the scientific community like the chromosomes are formed of nucleic acid and protein, chromosomes are found in the nucleus, and genes are located on the chromosomes.
