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
Answers
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?
Answers
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.

Which process of angiosperm reproduction often requires insects or other animals to take place?
mitosis
meiosis
fertilization
pollination
Answers
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.

Water conservation is the traditional and advanced practice of using water efficiently and reducing the wastage of water.
Water conservation is not a costly endeavor even though its environmentally beneficial.
Water conservation can be done as:
Only 1% of the Earth's water is available to humans for consumption, so the contamination of water should not be done. Water shortages have been predicted for nearly half of the states and some of them are facing severe water scarcity. Water conservation can be done free of cost, as doing rainwater harvesting, and also other processes can be applied to conserve water. The failure to conserve water will not lead to more contamination of water.Thus, the correct answer is Option C.

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.

What does the theory of evolution tell us about how organisms adapt to their environment over time? (4 points)
a
Natural selection occurs before changes in the environment.
b
A population changes in response to a change in the environment.
c
Environmental changes can be predicted based on changes in a population.
d
Natural selection leads to the survival of the population with the most complex traits.
Answers
Answer:
B
A population changes in response to a change in the environment
Explanation:
Choices A and C should be able to be eliminated pretty quickly. Natural selection is where organisms ADAPT. In order for them to change THEY need to adapt to something DIFFERENT. The only thing the organism should be adapting to is the environment, therefore there should be a change in it. Choice D simply says that organisms only live in a change in environment when complex traits are in place, which simply isn’t true.
Imagine going back in history when giraffes were much shorter than what they are today. Their ENVIRONMENT had much more tall plants than smaller due to other organisms consuming them which led to the giraffe evolving into the tall animals we know today. Being as tall as they are today, those tall plants aren’t so high for them and allow them to get the nutrients and food they need.

I'm answering Q1: the major ways in which humans are damaging the environment is cutting down trees. trees are homes for other animals like birds and koalas and so much more I can't name. if you cut down a tree an animal loses its shelter, the animal doesn't have a shelter to stay, the animal dies, the animal dies we we have no food. Also trees are very much needed and very important for us humans. trees release oxygen when they use energy from sunlight to make glucose from carbon dioxide and water. also cutting trees adds carbon dioxide to the air and removes the ability to absorb existing carbon dioxide.
