5. At the end of fall, most deciduous trees lose their leaves for the winter season. In fact, the word deciduous comes from the Latin word decidere, which means to fall down or off. There are, however, a handful of deciduous trees around these parts that have a tendency to keep their leaves past fall.

Match the functional groups with their structures:

evablogger [386]

The true answer of your question is :

OH : HYDROXYL GROUP

NH2 : AMINO GROUP

CH3 : METHYL GROUP ( but in rather broader terms, that functional group of formula CnH2n+1 where n is an integer is called ALKYL GROUP where by substituting n by 1,2,3... we obtain methyl for n = 1, ethyl for n = 2, and propyl for n = 3 )

COOH : CARBOXYL GROUP is the correct answer since carbonyl is characterized by the presence of functional group C=O in general the formula of the compound would be
R-C=O-R’ where R and R’ are alkyl groups like methyl for example. However the carboxyl group could be thought of as a summation of carbonyl + hydroxyl ( CO + OH ) resulting thus in COOH.

I hope you’ll understand everything, anyway if not i’m always here to help. ♥️

Identify the phases of Meiosis II described below.

Annette [7]

1. The lining up of chromosomes by the spindle fibers takes place at metaphase II phase. It is the second stage of meiosis II, the spindle draws the chromosomes towards the metaphase plate.

2. The formation of the nuclear envelope around each set of DNA takes place in telophase II. Along with the formation of the nuclear envelope, the process of cytokinesis also takes place in telophase II, producing four daughter cells, each comprising a haploid set of chromosomes.

3. The sister chromatids are pulled apart in anaphase II stage. In this phase, the sister chromatids are migrated towards the opposite poles of the cell with the help of protein fibers.

4. The centromeres are moved towards the poles of the cell at prophase II stage.

How do i describe the ATP molecule and its functions within the cell

Darina [25.2K]

ATP stands for denosine tri phosphate ..
formation:
it is formed in the respiration ..also 36 molecules of ATP are formed during break down of 1 glucose molecule ..
function:
its function is to provide energy ,,
how it provides energy:
when one phosphate molecule separate ATP is converted into ADP and energy is released..
and when one phosphate is separated from ADP AMP is formed and energy is released ..
