What is Sympatric speciation?Sympatric speciation refer to evolution of a new species or the creation of new species from the ancestal species that is alive and surviving while both of them continue to live in the same geographic region. In evolutionary biology and biogeography, sympatric refer to organisms that have ranges and their ranges overlap so that they occur together some places.
The individual are dependent on some physical needs like shelter, food and so on.
Therefore, An example of habitats where sympatric speciation occur is the North Rim and South Rim of the Grand Canyon.

33. Why is it beneficial that plants have two kinds of chlorophyll (a and b)?
Answer:
chlorophyll in plants complement each other in absorbing sunlight.
Explanation:
light with a wavelength of 460 nm isn't always substantially absorbed by means of chlorophyll a, but will as a substitute be captured through chlorophyll b, which absorbs strongly at that wavelength. the two forms of chlorophyll in flowers
It is beneficial to have two kinds of chlorophyll in photosynthetic plants because both types of chlorophyll work complementary to each other and allow maximum absorption of light in the blue to red spectrum.
What do you mean by Chlorophyll?Chlorophyll may be defined as the green-colored pigment in plants, algae, and cyanobacteria that is essential for photosynthesis.
Chlorophyll A absorbs the light of wavelength 400 to 450nm with maximum intensity and 650 to 700nm with minimum intensity.
Chlorophyll B absorbs the light of wavelength 450 to 500nm with maximum intensity and 600 to 650nm with minimum intensity.
Therefore, it is beneficial to have two kinds of chlorophyll in photosynthetic plants because both types of chlorophyll work complementary to each other and allow maximum absorption of light in the blue to red spectrum.

Which plant structures are common to all angiosperms?
spores
flowers
cones
endoskeleton
Answer:
Option B. (Flowers) is correct!
Explanation:
A plant structure common to all angiosperms is the flowers, which are reproductive structures formed from four whorls of modified leaves. The angiosperms have two structures that ensure their reproductive success: flowers and fruits, being the flowers the one that forms a cooperative evolutionary relationship with insects, and other animals to help disperse the pollen from the female plant gametophytes.

O Reduction in Iron pollution in ocean sediments
O Reduction of bycatch
Reduction of the greenhouse gas carbon dioxide in the atmosphere
Reduction of the human impact on marine species diversity
Answer: Reduction of the greenhouse gas carbon dioxide in the atmosphere
Explanation:
phytoplankton use photosynthesis to take the sun’s light waves and convert it into energy. They also take carbon dioxide and convert it into oxygen for other organisms to breathe.
Earth orbits the Sun every 365 days, causing seasonal patterns that vary by location. In the winter, the Northern Hemisphere is tilted away from the Sun, and receives the smallest amount of solar energy than any other time of the year. What can be expected in the Northern Hemisphere during this season?
A) warmer temperatures and decreased daylight
B) cooler temperatures and increased daylight
C) warmer temperatures and increased daylight

If you soak seeds in water to soften them, and then cut them in half and stain them with iodine, most of the inside of the seed will change color, turning a purplish-black. What substance is the iodine reacting with to cause this color change?
Answer:
Starch
Explanation:
Starch consists of amylopectin and amylose, and is found in plants. In the presence of iodine, amylose starch turns a dark purple or blue color, due to the absorption of different wavelengths of light than before.
