Alcohols and sugars both contain the hydroxyl group. Which property does the hydroxyl group have?

2 answers:

6 0

They are polar as a result of the electrons more grouped upon the electronegative atom.

they can form hydrogen bonds with water molecules, helping acting as a solvent with organic compounds such as sugar.

The hydroxyl group is a functional group that is characterized by presence of oxygen bonded to hydrogen and it has the formula OH. Hydroxyl group is hydrophilic (dissolve easily in water). They can form hydrogen bonds with water molecules. They are polar due to the concentration of opposite types of charge on each end of the group.

Why does a rain forest have more bio diversity then a temperature forest

kotykmax [81]

Tropical forests, including evergreen rainforests, cloud forests, seasonal deciduous forests and mangrove forests, have the highest biodiversity of all terrestrial biomes. Tropical rainforests, in particular, cover less than 7 percent of the Earth’s surface but harbor an estimated half of all existing plant and animal species. A small plot can yield hundreds of tree species – as many as all North American temperate and boreal forests combined -- and one reserve in Peru has more than 1,200 different butterflies. Dry tropical forests contain some of the same species as rainforests but fewer species overall. Among the major temperate forest types (temperate coniferous, rainforest, deciduous and mixed forests), temperate deciduous and mixed forests -- which include both deciduous and coniferous species -- have the highest biodiversity. Some temperate coniferous forests consist of only a few tree species, but the chatter and songs of great varieties of birds often fill their borders.( from the science book online )

A student is measuring the effect of different temperatures on the effect of enzymes in biological systems. What temperature ran

viktelen [127]

Answer:

A. 25 °C, 30 °C, 35 °C, 40 °C, 45 °C

Explanation:

Each enzyme has a temperature at which it works best. In humans and many animals, that temperature is around body temperature (37 °C or 98.6 °F). Most enzymes are denatured and work poorly at 40 °C (104 °F).

That automatically eliminates Option B.

I would pick a temperature close to 37 °C (98.6 °F) and temperatures at intervals above and below that.

Option D is wrong because it includes no temperatures above body temperature.

Option C is wrong, because it includes temperatures of 45 °C and 55 °C, at which the enzymes will be denatured.

That leaves Option A as the best answer. It includes only one temperature above 40 °C.

Which of the following cell organelles contains instructions for making proteins?

Juliette [100K]

Answer:

ribosomes

Explanation:

As mentioned earlier, ribosomes are the molecular machines responsible for protein synthesis. ...

In eukaryotes, ribosomes get their orders to synthesize core proteins, where segments of the DNA (genes) are transcribed to produce messenger RNA (mRNA).
