Answer:
Leaves are the site of the food making process called photosynthesis. In this process, carbon dioxide and water in the presence of chlorophyll (the green pigment) and light energy are changed into glucose which is sugar. This energy rich sugar is the source of food used by most plants.
Explanation:
The pigments have a similar
structure of 40 carbon atoms covalently bonded in a chain. Carotenoids contain oxygen atoms in their chemical structure (retinyl functional group) while
xanthophyll does not. This makes carotenoids more non-polar compared to xanthophylls,
hence move farthest in chromatography
paper using a nonpolar mobile phase. Chlorophyll
pigment, on the other hand, has chlorin rings (which are larger) as functional
units hence move slowly in chromatography.
Photosynthetic rates
can be measured by either the amount of
oxygen they consume per particular time period
or the amount of carbon dioxide produced per particular time period. This
is conducted while immersed in water so
as to measure bubble rate formation in case of oxygen production or the change
in water pH in the case of carbon dioxide consumption.
When autumn approaches, the amount
sunlight received by the plant is reduced due to longer night than days. Deciduous trees have adapted by losing
chlorophyll a and b pigments (most important in photosynthesis)
during this time. This leaves a higher amount of the other red and yellow pigments hence making the leaves change from
green to yellow-red.
It is believed that this
is the result of an ancient endosymbiotic
relationship between a protist and a
eukaryotic cell. The protist generates energy
that the eukaryotic can utilize in its growth and reproduction while
the protist is sheltered. This relationship became obligatory symbiosis over
time.
C. Precipitation fits the definition for “falling rain or snow”
Gastric inhibitory peptide (GIP) a digestive hormone is secreted when fats and carbohydrates, especially glucose, enter the small intestine.
- A member of the secretin family of hormones, glucose-dependent insulinotropic polypeptide is an inhibitory hormone.
- It is sometimes referred to as gastric inhibitory polypeptide or stomach inhibitory peptide.
- The enteroendocrine K-cells, which are widespread in the small intestine secrete GIP.
- The hormone gastric inhibitory polypeptide, which is released by intestinal mucosal cells, prevents the stomach from producing hydrochloric acid.
- Additionally, it improves the islets of Langerhans' beta cells' ability to secrete insulin, which results in a considerable increase in blood insulin concentrations following oral glucose delivery.

<u>Answer:</u>
Genetic disorder that can result when sister chromatids fail to separate properly is likely to occur in meta-phase (m-phase) because in mitosis during m-phase there is separation of DNA to two equal halves.
<u>Explanation:</u>
- Genetic disorder is the problem that is caused by the abnormal activities in gene.
- This is also called mutation which may cause due to error during replication of DNA and also due to some environmental factors such as radiation exposure, smokes.
- So, during meta-phase, genes might not separate and genetic disorder might happen.
