Rachel counted all the earthworms in a square meter in her back yard and found she had 36. She went back a week later and found she had only 30.Rachel knew that this was far too few to maintain her lawn so she decided to study the population for a couple of weeks. She found there were 9 worms born per week and 5 died per week. She also found 10 left for a nearby plot of land and 8 worms came from nearby plots during that week. Was the population growing or shrinking

3. How do seasonal changes in temperature, water availability and sunlight affect ecosystems?
4. Propose 5 ways that humans can help minimise the negative effects both natural events and human impact can have on ecosystems.
Answer:
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.

Angiosperms are such a successful group of plants because of how well they recruit animals for pollination and the diverse way they disperse their seeds. Describe two ways animals spread angiosperm pollen and two ways fruit is dispersed.
Animals can be very important to plant reproduction in two ways—spreading pollen and spreading seeds. Pollen contains a plant’s sperm.
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).

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.
Decide whether each statement about urine formation is true or false.

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.

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.

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.

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.

Melted snow from the Sierra Nevada mountains and other mountain ranges is an important water source for much of California. Using evidence, explain why a lack of snow in the mountains could make drought cycles worse over time.
Answer:
DIS IS KARMA
Explanation:
:))))))))
Answer:
A lack of snow in the mountains could make drought cycles worse over time because of the water cycle.
Explanation:
When snow melts, it cycles into rivers, into lakes, and underground. Without this water, these resources may dry up more quickly in the summer. If water resources are too low, then people may need to use less water for personal use and agricultural use.

Homeostasis means to maintain balance or equilibrium
True
False
Answer:
True.
Explanation:
Homeostasis is the process of maintaining balance inside your body.
Ex:
When you sweat, your body is trying to cool down your body temperature from being hot to cool.
When you eat food, the excess comes out as waste.
When you shiver, your body is trying to make you warm when you are cold.
Most other types of cells have the ability to replace damaged molecules and organelles. Red blood cells have a reduced capacity for repair and thus only survive for about four months. Construct an explanation based on the structure of red blood cells for why red blood cells are unable to repair damaged proteins.
Answer:
The red blood cells do not repair by themselves, that is why they must be destroyed in the spleen or rather phagocytosed, so that they are then newly formed in the spleen.
Red blood cells are unable to repair protein damage since one of these infleunctions is their anucleation.
Explanation:
The clearance of red blood cells is essential since the half-life of this cell is a few months, once these months have passed the red blood cell will not fulfill the function in the same way.
They are characterized by having a tetrahedral protein that is related to gases such as oxygen according to its partial pressures.
This protein called hemoglobin is responsible for transporting oxygen to the tissues and oxygenate them.
