What would happen to species if it stopped reproducing?
Answer:
The event that would be the result of a species halting its reproducing would be the species becoming endangered and eventually becoming extinct.
Explanation:
Since animals eventually die, the reproduction creates additional animals, in which replace the dead ones. If the species stopped its reproduction, the species would die off because there are no other animals of that species to replace the dead ones.

Fossils are the preserved remains or traces of plants and animals that have lived on Earth throughout Earth's history. How does the fossil record of animals compare to animals that exist today
Answer:
Fossilized animals are ancestors of animals that exist today
Explanation:
A fossil is a preserved remain or trace of an organism (e.g., an animal) in a sedimentary rock which lived in a past geological age. Moreover, a fossil record is a group of fossils that are arranged chronologically and/or in taxonomic order. The fossil record provides direct evidence of extinct organisms and shows the progression of the evolution of organisms (from ancestors to descendants) over millions of years. In consequence, the fossils from recent geological periods are more similar to organisms living on Earth today.

Explain how selective breeding is being used to
try to produce commercial peanuts that will not
cause allergic reactions in people.
Answer:
by bringing the peanuts that lack the allergic reaction proteins
Selective breeding is being used to produce commercial peanuts that will not cause allergic reactions in people by focusing on specific traits related to allergenicity.
The goal is to identify and breed peanut varieties that have reduced levels of allergenic proteins, particularly those known to trigger allergic responses in individuals.
The process involves selecting and breeding peanuts that exhibit low allergenic potential or lack specific allergenic proteins. This is typically done through extensive screening and testing of different peanut varieties to determine their allergenicity.
Peanuts with lower levels of allergenic proteins or novel varieties that lack specific allergenic proteins are favored for further breeding.
The selective breeding process then involves cross-breeding these selected peanuts to produce offspring with reduced allergenic potential. The offspring are evaluated for their allergenicity through laboratory testing and human trials, where allergic individuals are monitored for adverse reactions.

Many scientists worry that the influence humans have on the biogeochemical and hydrologic cycles will cause lasting damage to Earth. Make a list of the activities you perform in a day that may impact one of these cycles. Explain how you are interacting with the cycle and how that could be affecting your local ecosystem. What can you do to decrease your impact?
Answer:
Driving a car, smoking, burning of woods for heating purpose and cooking food.
Explanation:
Driving a car, smoking, burning of woods for heating purpose and cooking food are the activities that are performed in our home daily. These activities greatly affected the biogeochemical and hydrologic cycles by increasing the concentration of carbondioxide gas in the atmosphere. Burning of fossil fuels in the car engine and burning of woods releases carbondioxide gas that causes air pollution. The use of electric cars and electric heater can decrease the impact on these biogeochemical and hydrologic cycles.

what is the mass in grams of 300 ml of salt water with a density of 1.30 g/cm3
Answer:
The mass of salt water is 390 grams
Explanation:
To calculate the mass of salt water, we use the equation:
\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}Density of substance=
Volume of substance
Mass of substance
Density of salt water = 1.30g/cm^31.30g/cm

Volume of salt water = 300 mL = 300cm^3300cm
3
(Conversion factor: 1mL=1cm^31mL=1cm

)
Putting values in above equation, we get:
\begin{gathered}1.30g/cm^3=\frac{\text{Mass of salt water}}{300cm^3}\\\\\text{Mass of salt water}=(1.30g/cm^3\times 300cm^3)=390g\end{gathered}

Why is the find of the Chilesaurus important in understanding the evolutionary lineage of theropods?
Answer:Scientists once believed that all theropods were carnivores. However, recent research showed that some theropods evolved to eat plants. The fossil indicates that the new species of dinosaurs evolved to eat plants earlier than some of the other theropods. So, this new species may help scientists piece together an evolutionary lineage of theropods that ate plants.

Using nuclear fusion as an energy source
Cost
Using stem cell technology to cure disease
Answer:
Ocean desalination, Using nuclear fusion as an energy source and using stem cell technology to cure disease.
Explanation:
Ocean desalination is the major problem that occurs due to removing of nutrients that is present in the ocean water because of human activities. These nutrients are essential for the marine animals so for solving this problem, we should use other alternative energy resources in order to reduce ocean desalination. Using nuclear fusion as an energy source is a good idea but it can't be implemented on the earth because it requires 100 million degrees Celsius which is impossible to generate. Using stem cell technology to cure disease is a great idea which can cure many diseases in the human body. This available technology is used by replacing damaged cells with the healthy cells.
