I only have an answer for number 24, I'm sorry! But one piece of evidence is the DNA sequences, they have discovered that humans and monkeys/apes share a common ancestor through DNA. Another would be fossils, scientists have fossils to show great similarities in the skull and jaw structure, along with the legs, comparing to humans.
During nitrogen fixation, bacteria breaks nitrogen gasses down into a usable form for plants.
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.
Explanation:
the colors are not bright but not too dark , the material seems like not soft , and the patterns are not like anything I've seen before
Label O is organic material, label A is topsoil, label B is subsoil and label C is weathered rock. They represent different soil layers.
<h3>Soil layers</h3>
Soli layers, also called horizons, refer to the different layers observed on the ground.
The topsoil is a layer of soil composed of a mixture of sand, silt, clay and organic material referred to as humus.
Weathering rocks refer to the dissolved rocks and/or minerals on the Earth's surface.
Subsoil refers to the layer under the topsoil on the surface of the ground.
