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.

Answers

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!

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%

Answers

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%

It might be unhelpful to repeat the answer but it is B. 50%

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

Answers

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.

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

Answers

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.
