Answer: Some organisms navigate competition for space by specializing on different niches or depths in the intertidal. When scarce space does open up, organisms that are the fastest dispersers will colonize the space first and outcompete the other organisms. As the tides rise and fall, the salinity (salt concentration) constantly changes. Animals living in the intertidal zone must be able to tolerate wide salinity variations. If sufficient nutrients are available, intertidal animals reproduce rapidly, so they constantly compete for space, light, and food.
Explanation:
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.

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.

If there are 21,000 Joules (J) of energy available to the producers, how much energy will be transferred to the next trophic level?
Answer:
If 10,000 joules of energy is available to the producer, then only 1000 joules of energy will be available to the primary consumer and only 100 joules of energy will be available to the secondary consumer.

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.
List various ways that humans impact the environment and change the ecosystems in which they live. Include your explanation how this can impact the population of animals that live in these ecosystems.

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.

What happened to the biodiversity of a managed ebony forest as human population increased?
A) Biodiversity increased.
B) Biodiversity decreased.
C) Biodiversity remained the same.
The increase in human population will lead to decrease in biodiversity. This is because as the human population increases they need more resources. Thus, the correct option is B.
What is Biodiversity?Biodiversity is the total number of living organisms present in a particular area. The biodiversity of an area is dependent upon a number of factors like habitat, competition among species, resources, and climatic conditions. Usually, there are three types of biodiversity which include genetic, species, and ecosystem diversity.
The increase in human population in an area creates a problem for the biodiversity because with the increase in population comes a need to convert natural habitats to land for human consumption and shelter.
Therefore, the correct option is B.

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