Which process of angiosperm reproduction often requires insects or other animals to take place?
mitosis
meiosis
fertilization
pollination
Answer:
pollination
Explanation:
edg 2021
The pollination process of angiosperm reproduction often requires insects or other animals to take place, hence option D is correct.
What is pollination?The transfer of pollen from the anthers to a stigma of the same species, followed by the germination and expansion of the pollen tube to the micropyle of the ovule, are all necessary for effective pollination.
Wind, water, and animals, particularly insects and birds, all contribute to pollen transmission. The union of these male and female gametes occurs during pollination.
Pollen from the male anthers is picked up by the wind or other creatures, particularly insects and birds, and transported to the female stigma.
Therefore, pollination depends on other factors to transfer the pollen because pollen cannot travel alone from the anthers to the ovules.

(03.03 MC) Which element is represented by the electron configuration in example B? Example B: 1s22s22p63s23p64s23d104p2 Polonium Sulfur Silicon Germanium
Answer:
Germanium
Explanation:
The electronic configuration 1s²2s²2p⁶3s²3p⁶4s²3d¹⁰4p² is that of an atom of an element with atomic number 32.
The element that has an atomic number of 32 in the Periodic Table of elements is Germanium with the symbol Ge. It belongs to group IVA of the periodic table as it has four electrons in its valence shell. Its ten 3d electrons are inner electrons, whereas the two 4s and 4p electrons constitutes its valence shell electrons. It also belongs to the period 4 of the periodic table.
Germanium is a silvery-white semi-metal. It is brittle. Germanium is a semiconductor.

Recently, due to rapid urbanization and mechanization residents of a city are suffering from harmful effects of the ultra violet rays. Depletion of which layer is likely to have led to this situation? A. oxygen B. carbon dioxide C. nitrogen D. ozone E. methane
Answer:
D
Explanation:
The correct answer would be ozone.
Only the depletion of the ozone layer can increase the amount of ultraviolet rays in the atmosphere thereby causing harmful effects to the residents. The ozone layer originally forms a shield that filters off ultraviolet rays from the radiation coming from the sun. By doing so, the ultraviolet ray that gets to the earth is minute and biological organisms are thus insulated from the harmful effects of the ray.
The ozone layer is gradually depleted by pollutants such as CFC which is released into the atmosphere by the actions of man. As urbanization and mechanization increase, more and more of these ozone degrading pollutants are released leading to a rapid depletion of the ozone layer.
The correct option is D.

What do enzymes have the ability to do?
Answer:
Enzymes create chemical reactions in the body.
They help your body perform very important tasks.
Enzymes increase the rate of chemical reactions without being consumed by themselves or being permanently altered by the reaction and increase the reaction rate without altering the chemical equilibrium between reactants and products.
What are Enzymes?Enzymes are defined as proteins that act as biological catalysts by speeding up chemical reactions where the molecules on which enzymes can act are called substrates, and enzyme substrates are converted into different molecules known as products.
It is called biological catalyst which is present in living organisms which increases the rate of reactions taking place within the body. Enzymes are highly specialized enzymes that catalyze a single chemical reaction or a number of closely related reactions.
Thus, Enzymes increase the rate of chemical reactions without being consumed by themselves or being permanently altered by the reaction and increase the reaction rate without altering the chemical equilibrium between reactants and products.

Answer:
Three cups of the same size are filled with the same mass of fresh water. One cup is put in a bucket of ice water so the water becomes cold, but does not freeze. One cup is heated so the water becomes hot, but does not boil. One cup is left at room temperature. At the macroscopic level, what someone can see with just their eyes, there appears to be very little difference in the volume of water between the three cups. However, at the molecular level, there is a difference in volume.

When our prehistoric ancestors studied the night sky they noticed that 5 objects moved through the constellations, what are these called?
Answer:
planets
Explanation:
In the past, it was observed that little points of light moved through the constellations. Nowadays, we known that these points are planets which orbit around the sun, while stars remain fixed in the sky. This phenomenon is due to the fact that planets are so much closer to the Earth than the stars. From Earth, five planets can be seen with naked eyes (i.e., Jupiter, Saturn, Mars, Venus and Mercury).
