it will lead to extinction of wildlife and also leads to erosion
Explanation:
1)) The average depth of a lake is 10 meters. Do you think sunlight acts a limiting factor the same way it does in the ocean? Why or why not?
2)An area with a high population of crayfish in local lakes and rivers has begun experiencing acid rain, rain that has a pH of 3.0 - 4.0. Predict how this rain will impact the crayfish population.
Answer:
No.
Explanation:
No, the sunlight does not act as a limiting factor the same way it does in the ocean because the lake has lower depth as compared to ocean which is very deep i. e. more than 3000 meters where sunlight does not reach and we know that sunlight is very important for the survival of plants. Sunlight reach in the water about 1000 meters so plants can survive and do photosynthesis due to its low depth.
Acid rain will impact the crayfish population because acid rain decreases the pH of water and this lower pH causes death of the crayfish and also the food of crayfish and thus lower the population of crayfish due to unavailability of food..

Which is the pathway for information through a neuron? dendrite → axon → cell body → axon terminals axon terminals → axon → cell body → dendrite dendrite → cell body → axon → axon terminals cell body → dendrite → axon → axon terminals
Answer:
dendrite → cell body → axon → axon terminals
Explanation:
The pathway for information through neuron are dendrite → cell body → axon → axon terminals and this because Dendrite is the input zone of nerve cell where neuron can receive information from another nerve cell.
Cell body is the part of the neuron that contain nucleus and it is link to the dendrites and it send signals to the axon.
Axon is a long nerve cell that join the cell body at a terminal called axon hilock and this conduct electrical impulses.
Axon terminal contain synaptic vessicles and it is synapse to other terminal and it is the out put zone of neuron. It is the out put zone where information is expell out

Answer:
Mutualism, commensalism and parasitism.
Explanation:
Interactions among the organisms such as fish, corals, lobsters, clams, seahorses, sponges, and sea turtles etc can be observe in the reef environment. reef environment refers to the coral reef which are present in the underground ecosystem. It is made up of calcium carbonate that provides habitat or shelter to thousands of animals. Some behaviours are mutualism, commensalism and some are parasitism.
The reef depicts the interaction of various organisms such as crabs, lobsters and sponges. The reef environment is made up of corals. The reef is made on the deposits of calcium carbonate hence shelter bed for thousand of organisms
Some behaviors like the mutualism, commensalism, and parasitism can be found. The mutualism is based on the mutual harmony of these organisms with each other in the same environment. The parasitism depicts the dependence of the small organisms that feed and depend on the larger organisms for shelter and food.Thus they depicts mutualism, parasitism, and commensalism in the environment.

A Burn the food and determine the change in temperature from the beginning to the end.
B Dissolve the food in water and determine how it changes the boiling point of the water.
C Burn the food and determine how much it raises the temperature of a known amount of water.
D. Dissolve the food in water and determine if it changes the standing temperature of the water.

I am the thing that goes bump in the night. The shadow-like figure all are too afraid to identify in their room. The silent stalker of your waking nightmares and lucid dreams. Do not worry, I can- but will not- hurt you. Your family, however, doesn't have such luck. Do not warn them that I will be following their every move, or it will lead to a grizzly fate for you and your bloodline. I hope that my message has given you closure for the events to come.
In the meantime, you can pray for your family. Maybe I'll have mercy.
The best procedure for a scientist to use in order to determine how many calories are in a certain food is burn the food and determine how much it raises the temperature of a known amount of water. Option C is correct.
When food is burned, it releases thermal energy in the form of heat. The amount of heat energy released can be measured by observing how much it raises the temperature of a known amount of water. This is because water has a specific heat capacity, which means it requires a certain amount of energy to raise its temperature.
By burning the food and using a calorimeter (a device used to measure heat), scientists can accurately measure the amount of thermal energy released. This energy can then be converted to calories, which is a unit of energy commonly used to measure the energy content of food.

Is using fossil fuels in generating electricity better or using renewable energy? why?
Answer:
Explanation:
Using renewable energy will always be better than fossil fuels.
This is because fossil fuels need a very long time to renew themselves. And we will run out of them long before they can renew themselves. Besides this, there is a more concerning and very alarming issue with using fossil fuels instead of other energy sources. Global warming and environmental destruction is a very big problem for us in the 21st century. The air is more and more polluted. Temperatures are rising and oceans are rising with them. We will lose the ability to grow food and raise animals in the future if we continue like this.

Define the following types of sexual reproduction: Binary fission, budding. fragmentation, parthenogenesis
Answer:
Binary fission-Binary fission, asexual reproduction by a separation of the body into two new bodies. In the process of binary fission, an organism duplicates its genetic material, or deoxyribonucleic acid (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA.
Budding-Budding is a type of asexual reproduction in which a new organism develops from an outgrowth or bud due to cell division at one particular site. The small bulb-like projection coming out from the yeast cell is called a bud.
Fragmentation-Fragmentation in multicellular organisms is a form of asexual reproduction in which an organism is split into fragments. Each of these fragments develop into matured organism, full grown individuals that are genetically and morphologically identical to their parents.
Parthenogenesis-
Parthenogenesis is a form of reproduction in which an egg can develop into an embryo without being fertilized by a sperm. Parthenogenesis is derived from the Greek words for “virgin birth,” and several insect species including aphids, bees, and ants are known to reproduce by parthenogenesis.

Overfishing is a huge problem throughout the world. Could lab grown fish solve the problem of world hunger and overfishing at the same time? Explain. I will give brainliest
Answer:
In some ways yes it could
Explanation:
The state of the rest of the world’s fisheries is far less pretty. Widespread overfishing and shrinking global fish stocks, rising health concerns associated with toxic contamination (including mercury and plastic) of wild fish, and increasing sustainability and health concerns around aquaculture are just some of the challenges now facing the global marine industry. As prominent US marine biologist Dr. Sylvia Earle told the UN in 2015, “The ocean is large and resilient, but it is not too big to fail.”
That’s where “clean fish” come in. Without the ocean pillage or negative health impacts currently associated with captured and farmed fish, cell-grown fish can undoubtedly help ease some of the pressure on the world’s natural ecosystems. “We want to show the public we are doing this for the right reasons, and that we are working on clean fish primarily as a conservation issue” says Finless Foods’ Mike Selden. “Yes, fish is a high-value product. But I also think it is important people know we’re doing this as a conservation issue. Bluefin tuna species are on and off the threatened species list, partially because it’s so expensive. We can take the pressure off these increasingly rare and wild populations.”
What is different about normal cell division and cancer cell division?
Answer/Explanation:
Normal cell division is a very controlled process.
There are several checkpoints where the cell ensures the cell is:
receiving the correct signals to dividethat the environmental conditions are favourable for the cell to dividethat there is no damage to the DNA.However, cancerous cells proliferate uncontrollably. This is because they can bypass the checkpoints and divide without the necessary signals. This means cell division keeps occurring even when conditions are unfavourable and the DNA is damaged.

DNA replication happens before cell division in both prokaryotes and eukaryotes.
DNA replication represents a key step in the cycle of every cell, irrespective of whether they are prokaryotes or eukaryotes. The process happens during the interphase of the cell cycle - the S phase to be specific.
After DNA replication, cells generally proceed to the G2 phase where protein is synthesized before entering the mitotic phase of the cell cycle where division takes place.

In both prokaryotes and eukaryotes, DNA replication happens before cell division.
When does the cell divideIn both prokaryotes and eukaryotes, DNA replication occurs before cell division. DNA replication is the process by which a cell duplicates its DNA, creating an identical copy of the genetic material. It is a crucial step in the cell cycle to ensure that each daughter cell receives a complete set of genetic information.
In prokaryotes, which are organisms without a nucleus, DNA replication occurs in the cytoplasm. The circular DNA molecule present in prokaryotes, called the bacterial chromosome, is replicated before the cell divides through a process called binary fission.

A factory located near the top of a hill leaks chemicals into the groundwater. How could this leakage affect the groundwater at the bottom of the hill? Could more than one place be affected? Explain.
Answer:
Explanation: ground water contamination is nearly
always the result of human activity. In
areas where population density is high and human
use of the land is intensive, ground water is especially vulnerable. Virtually any activity whereby
chemicals or wastes may be released to the environment, either intentionally or accidentally, has
the potential to pollute ground water. When
ground water becomes contaminated, it is difficult
and expensive to clean up.
To begin to address pollution prevention or remediation, we must understand how surface waters
and ground waters interrelate.
The water present underneath the Earth exterior between rocks and soil spaces is called groundwater.
The deliberate upsurge of contaminants in the water is called water pollution it modifies the natural rich environment of water microbiota and composition.
Human activities like the release of chemicals from industries and factories in water bodies result in water and soil pollution.
Chemical leakage from factories runoff adds to a water body at the bottom of hills impacting its quality.
The polluted water with chemicals will result in diseases and death of the microbiota of aquatic life and terrestrial organism consuming it.
