How does human consumption of limited resources impact the biosphere? 1 paragraph
Answer:
Human use of land has negative impacts. Human activities contribute to the erosion and pollution of beaches. ... More of the rainwater runs off leading to increased erosion and drier soil. Deforestation of land can also lead to desertification and a loss of biodiversity.The burning of fossil fuels and the growth of animal agriculture has led to large amounts of greenhouse gases (such as carbon dioxide and methane) in the atmosphere. Higher concentrations of greenhouse gases trap more heat in the biosphere and result in global warming. In turn, this drives climate change.Humans affect the quality, availability, and distribution of Earth's water through the modification of streams, lakes, and groundwater . ... The activities of humans have significantly altered the biosphere , changing or destroying natural habitats and causing the extinction of many living species.

Which of the following processes causes
sinkholes to form?
A. erosion of sediment by runoff
B. deposition of sediment by a river
C. deposition of calcite by groundwater
D. erosion of limestone by groundwater
Answer:
A. erosion of sediment by runoff
Explanation:
The formation of sinkholes involves natural processes of erosion or gradual removal of slightly soluble bedrock (such as limestone) by percolating water, the collapse of a cave roof, or a lowering of the water table. Sinkholes often form through the process of suffosion.
Answer:
A sinkhole is a hole in the ground that forms when water dissolves surface rock. Often, this surface rock is limestone, which is easily eroded, or worn away, by the movement of water. ... Water collects in these collapsed sections, forming sinkholes. Sinkholes also form when the roofs of caves collapse.

5. Explain the genotypes and phenotypes of skin color.
Part C When a material is heated, the change in temperature depends on the kind of material and its mass. Different objects can absorb and release different amounts of energy when heated and cooled. This property is called heat capacity. How might scientists apply this property to design something useful in the real world? Give one or two examples.
Answer:
Not really sure about this question but what I think is,
So for example, metal..Metal has a very low specific heat capacity, but we use it pretty much in all our lifetime right? Things that have low heat capacity have very high capacity if that makes sense. Things like water and oil, they take more energy to get heat up or get hot. Its funny because its what makes our planet survivable. 70% of our planet is of course water and radiation (light and heat) from the sun strikes 70% of water. Meaning its not heating anything up so quickly. Hope this somewhat helps you out and gives you an idea on what the question is talking about :) Enjoy!

1 . What happens in the population if the mutation phenotype is helpful
2. Why does that happen for that population that has a helpful phenotype?
3. How does this mutation continue to exist in a population?
Answer:
1. The population will increase as they're better adapted to their environment and have a higher survival rate due to this helpful phenotype.
2. This happens to the population because this helpful phenotype might lead to less exposure to predation in which leads to a better survival fitness for the organism.
3. This mutation continues to exist as the organisms continue to successfully reproduce into the population due to being able to survive for longer.
Why are cells of different shapes and sizes? Give suitable examples.

Answer:
The second one and the third
Explanation:
The human population is in an era of
growth.
O A. linear
B. slowing
O C. exponential
Answer:
C
Explanation:
because the human population is constantly rising and it has become a problem because we are using up our resources. linear means it stays the same. slowing means it's going down more than up and exponential means it is continuously going up
Mediterranean forests, dry woodlands, and shrublands often have plants called sclerophytes living in them. What adaptation do these plants have that help them survive in this biome?
Answer:
he special characteristics that enable plants and animals to be successful in a particular environment are called adaptations. Camouflage, as in a toad's ability to blend in with its surroundings, is a common example of an adaptation. The spines on cycad leaves, keep animals from eating them.
Explanation:
Plants adapt to their environment from necessity. Plants may also adapt by growing lower and closer to the ground to shield themselves from wind and cold. Desert environments may have some of the following adaptations, these help the plant to conserve food, energy and water and still be able to reproduce effectively.

A Three-leaf clover is dominant (T) to four leaves (t). What is the probability of an offspring having 4 leaves when you cross a heterozygous clover with a four-leaf clover?
O 25%
O 50%
O 75%
O 0%
Answer:
%50
Explanation:
Heterozygous = 2 different alleles (Tt)
4 leaf clover = 2 recessive alleles (tt)
T is dominant over t, so with the combination of Tt three leaves are expressed, rather than four leaves
For a recessive trait (four leaves) to show 2 recessive alleles are needed
To find the percentage of the offspring to have four leaves a punnet square should be created
To find the percentage divide the number of four leaf offering with 4 and multiply by 100
2÷4×100=50
= 50%
que sistemas artificiales utiliza el hombre para recoger agua que sistemas existen de forma natural
Answer:
Haciendo almacenamiento y excavación en un área grande, mientras que los estanques son los sistemas utilizados para recolectar agua.
Explicación:
El sistema artificial que el hombre usa para recolectar agua es la construcción de un gran almacenamiento de concreto y la excavación de un gran terreno que recolecta agua de lluvia y puede ser utilizado por la gente para su uso diario, mientras que por otro lado, los estanques son el sistema natural donde el agua del la lluvia se acumula naturalmente. Esta agua es utilizada por la población que vive alrededor de ese estanque. Ambos sistemas proporcionan agua para el uso diario, como lavar, beber y cocinar, etc.

The immune system has both specific and nonspecific defenses against viral infections. Which statement describes a nonspecific response of the immune system in fighting viral infections?
A. T cells are produced to search out and destroy the viruses.
B. Memory B cells are activated to rapidly respond to the viral infection.
C. Plasma cells quickly replicate and release antibodies that bind to the viruses.
D. Virus-infected cells produce interferons that lead to the inhibition of viral replication
Answer:
C
Explanation:
I just did this same question
Virus-infected cells produce interferons that lead to the inhibition of viral replication and act as a nonspecific response of the immune system in fighting viral infections. Therefore, the correct statement is option D.
What are interferons?The immune system has two types of responses to viral infections: specific and nonspecific. Interferons are signaling molecules produced by virus-infected cells to activate antiviral defenses, such as apoptosis in infected cells. This refers to the nonspecific response of the immune system in fighting viral infections
Interferons function by alerting the immune system about the presence of a viral infection. Interferons can also stimulate the production of other immune cells, such as natural killer cells and macrophages to eliminate the infected cells.
Interferons have been also used to treat viral infections, such as hepatitis B, and are the nonspecific defenses that act as a first line of defense against viral infections.
Therefore, interferons that lead to the inhibition of viral replication are the nonspecific response of the immune system in fighting viral infections.
