Which sentence describes an example of a positive feedback loop?
A: Warm blooded animals were when they get too hot. Sweating as a method by which the body close itself.
B: A thermostat regulates. Temperature by turning a furnace or air conditioner on and off.
C: When blood flows from a mild cut, blood clots form to prevent excessive bleeding.
D: As oceans get hotter, they release more CO2, which then increases atmospheric and ocean temperatures.
Answers
The example of a positive feedback loop from the provided options is D: As oceans get hotter, they release more CO2, which then increases atmospheric and ocean temperatures.
Explanation:The question relates to the concept of feedback loops in biological systems, particularly the difference between negative and positive feedback loops. The sentence that describes an example of a positive feedback loop is: As oceans get hotter, they release more CO2, which then increases atmospheric and ocean temperatures (option D). This example illustrates how a change in the system leads to an increase in the response, further promoting the initial stimulus, which is characteristic of a positive feedback loop. In contrast, negative feedback loops involve actions that counteract a change, aiming to maintain or reduce the response.
why must gametophyte cells divide by mitosis
Answers
Answer:
Haploid spores grows by mitosis and develops into gametophytes. In plants, there’s a little break between meiosis and the production of sperm and eggs. During that break, a separate little haploid plant grows.
In plants, meiosis occurs to produce the gametophyte. The gametophyte is already haploid, so it produces sperm and egg by mitosis.
So in other words it is important.
Hope this helps and have a great day!!!

An increase in skin cancer can be traced to a decrease in atmospheric Ozone.
Explanation:
Exposure of the skin to ultraviolet rays is a major risk factor that triggers skin cancer and is one of the growing concerns in recent times. BCCs or basal cell carcinoma is also known as rodent ulcers and occur generally in the areas exposed in the sun which damages the local tissue in human beings. Patients with this disease are usually fair skinned and burn more than dark skinned people in sunlight.
It may also develop during childhood, when a child is exposed in the sun for long periods. One of the most serious forms of skin cancer is Malignant melanoma which happens due to exposure of the body to the harmful UV radiations which in turn happens due to the ozone layer depletion, which stops the harmful rays of the sun from coming to the earth.

A. Biodiversity expansion
B. Biological augmentation
C. Pollution cleanup
D. Bioremediation
Answers
Biological agumentation is the process where plastic-eating fungi are sent to landfills.
Answer: Option B
Explanation:
The process of using living microbes to clear the landfills is called as biological agumentation or bioaugmentation. Bioaugmentation, for the most part, requires concentrating the indigenous assortments present in the area to decide whether biostimulation is conceivable.
Usually in this process, microbes such as bacteria, fungi etc are utilized. In case of landfills filled with plastics, fungi species which has the ability to degrade the plastic are used in this process.
Bioremediation is the correct term for the process where plastic-eating fungi are used in landfills to break down plastic waste into less toxic or non-toxic substances. The correct option is D.
The process where plastic-eating fungi are sent to landfills to break down the plastic materials is known as bioremediation. This is a waste management technique utilizing organisms such as fungi to remove or neutralize pollutants from a contaminated site, thus transforming hazardous substances into less toxic or non-toxic substances. An example of bioremediation is the use of certain plants to extract toxic metals from soils contaminated by mining operations, or using fungi to degrade plastics in landfills.
Which of the following is true about the flow of energy within ecosystems?
Answers
Sorry, but there are no any options.
Hello. This question is incomplete. The full question is:
"Which of the following is true about the flow of energy within ecosystems? A. Energy flows from living systems into the physical environment only. B. Energy flows both ways between living systems and the physical environment. C. Energy flows from the physical environment into living systems only. D. Energy does not flow between living systems and the physical environment."
Answer:
B. Energy flows both ways between living systems and the physical environment.
Explanation:
Energy lives in a constant flow within ecosystems. This energy flows in both directions between living systems and the physical environment.
An important aspect to understand the transfer of energy within an ecosystem is the understanding of the first fundamental law of thermodynamics that says: "Energy cannot be created or destroyed, but transformed". As an illustrative example of this condition, we can mention sunlight, which as a source of energy, can be transformed into work, heat or food depending on photosynthetic activity; but in no way can it be destroyed or created.
Another important aspect is the fact that the amount of energy available decreases as it is transferred from one trophic level to another. Thus, in the examples given above of food chains, the grasshopper obtains, by eating the leaves of the tree, chemical energy; however, this energy is much less than the solar energy received by the plant. This loss in transfers occurs successively until the decomposers are reached.

Which of the following best explains why clear-cutting forests is more destructive than selectively cutting down trees in forests? a. Clear-cutting eliminates all trees leaving none behind to maintain soil fertility or house native animals. b. Clear-cutting places the land at greater risk for wildfires. c. Clear-cutting makes land more attractive for human development. d. Clear-cutting causes less soil erosion than selective cutting.
Answers
Answer:
a. Clear-cutting eliminates all trees leaving none behind to maintain soil fertility or house native animals
Explanation:
The clear-cutting is a process that is very dangerous and harmful for the environment, but also for the humans on the long term. Through this process, the vegetation is totally removed, all trees and shrubs are eliminated. This leaves the soil barren and vulnerable, as it doesn't have a protection from the erosion, thus it is eroded very quickly. Also, the soil losses the plants that have been keeping its fertility at a certain level, so it become infertile very quickly. There's no trees left so that the area can recover, and it will take a very long period that the nature can recover at those places. The animals lose their habitats, so they die out, and the ones that are endangered may even go extinct.

What is ATP?. What does it do?. How do organisms get ATP?.
Answers
ATP, or adenosine triphosphate, is the primary energy cash in cells. It discharges energy upon hydrolysis, which is utilized for different cell capabilities. Through cellular respiration of carbohydrates, organisms generate ATP.
ATP is basic for different cell works and goes about as a power hotspot for cycles like muscle withdrawal, nerve drive engendering, and substance union. ATP stores and transports compound energy inside cells. At the point when the cell requires energy, ATP goes through hydrolysis, delivering one of its three phosphate gatherings. As a result of this reaction, ATP is transformed into adenosine diphosphate (ADP) or adenosine monophosphate (AMP), both of which can be utilized for cellular functions. Life forms produce ATP essentially through an interaction called cell breath. In order to produce ATP, carbohydrates like glucose must be broken down in the presence of oxygen in this process. Cell breath incorporates a few phases: glycolysis, the citrus extract cycle, and oxidative phosphorylation, each adding to the union of ATP.Describe how a fossil would form through mineral replacement.
Answers
A fossil would from through mineral replacement by replacing the existing material of the animals bones with minerals, to become petrified. The Minerals will keep the fossil preserved longer.
Have a good day!!
Final answer:
A fossil can form through mineral replacement when the original organism's material is replaced by a secondary mineral, preserving detailed structures and aided by sediment accumulation and permineralization.
Explanation:
A fossil forms through mineral replacement when the original skeletal material of an organism is substituted molecule-by-molecule by a secondary mineral, such as silica (quartz), pyrite, dolomite, or hematite.
This process can preserve the fine cellular details of the original organism, despite a change in its composition.
Sediment accumulation is crucial in providing the minerals and pressure necessary for mineralization.
During permineralization, the sediments' minerals fully replace the organism, creating a mineral copy of the original organism, which can occur with or without replacement.

Identify what happens to light in this model of the greenhouse effect.
Answers
The greenhouse effect describes how light from the sun is absorbed by the Earth's surface, then reradiated back into the atmosphere as infrared radiation. This radiation is trapped by greenhouse gases, warming the planet. Human activities are increasing greenhouse gas concentrations, intensifying this effect.
Explanation:In the model of the greenhouse effect, light from the sun enters the Earth's atmosphere and is absorbed by the surface of the planet. This energy is then reradiated back into the atmosphere, in the form of longer-wavelength infrared radiation. Much of this infrared radiation is then trapped by greenhouse gases in the atmosphere, including water vapor, methane, and CO₂. This trapped heat energy warms the planet, a process which is similar to how a greenhouse works, hence the term 'greenhouse effect'.
An aspect important to note is that the greenhouse effect is essential for life on Earth, as without it, the planet would be too cold. However, human activities that increase the concentrations of greenhouse gases are intensifying this effect, leading to global warming and subsequent climate change consequences.
