Answer: c
Explanation: correct answer
Streak plates are used to test minerals because they show you the color of the mineral in powdered form. So, the correct option is C.
What are Streak plates?Small pieces of unglazed glass or porcelain are known as streak plates, and they are used in mineralogy to assess the streak color of a mineral. They are usually a few inches in length and about an inch in width.
The streak of a mineral is its color after it has been ground into a fine powder and rubbed across a streak plate. Because some minerals have recognizable colors that differ from their actual color, it can be helpful to identify them.For example, hematite is a dark brown mineral with bright red streaks. You can differentiate hematite from other dark brown minerals by looking at the color of the streaks.
Therefore, the correct option is C.

Which effect does deforestation have on the carbon cycle?
Answer:
Deforestation facilitates one part of the carbon cycle, increasing the CO2 in the atmosphere. It also prevents forests from absorbing any further carbon by destroying the trees. It, therefore, inhibits this aspect of the cycle and leads to increased levels of this greenhouse gas in the atmosphere.

·Why does it make sense that blood flow varies throughout different organs
It is important that blood flow varies throughout different organs because of differences in the metabolic activities of the different organs.
What is the circulatory system?The circulatory system refers to the system of organs and tissues which are involved in the circulation of blood around the body.
The circulatory system performs the essential function of delivering nutrients to tissues and cells as well as removing metabolic waste from them.
Since the different organs in the body perform specialized functions, some organs are actively involved in metabolic activities, therefore need greater blood flow.
Therefore, blood flow varies throughout different organs because of differences in their metabolic activities.

Brown hair is dominant and blonde hair is recessive.
The parents have the following alleles.
Bb
Bb
What color hair do the parents have?
A. One has blonde and the other has brown
B. Brown
C. Blonde
d. unable to determine
Given what we know, we can confirm that the parents have brown hair.
This has to do with how dominant alleles work. When an allele is dominant, it is because, in the presence of mixed alleles, this trait will always be the one reflected in the phenotype of the individual. Since the parents possess an allele for brown hair and one for blonde, but brown hair is dominant, both parents will have brown hair.
Therefore, we can confirm that both parents will have brown hair due to the dominant nature of the brown hair allele.

One person consumes the equivalent of five cows per year. Five cows consume a total of 39 million Calories of vegetation per year. One person only needs one million Calories a year to survive. Which statement best describes the efficiency of energy transfer in this scenario?
It is very efficient because the person can eat less.
It is inefficient because less energy is needed at the top.
It is very efficient because most energy is made by producers
Only a portion of energy from vegetation makes it to a person.
Answer:
It is very efficient because the person can eat less.
Explanation:
the common knowledge answer
Only a portion of energy from vegetation makes it to a person. The correct option is D.
What is energy efficiency?The definition of energy efficiency is the use of less energy to carry out a task or achieve a goal.
Ecological efficiencies at each trophic link determine the food chain efficiency (FCE), which is calculated as the percentage of energy fixed by primary producers that is transmitted to the top trophic level.
The energy supply accessible to trophic level N+1 divided by the energy used by trophic level N is the definition of ecological efficiency.
Only a percentage of the energy from vegetation makes it to a person, which best sums up the efficiency of energy transmission in this situation.
Thus, the correct option is D.

Non-vascular plants use diffusion as they don't have vascular tissue to bring the water from the soil. Germination means to grow and pollination is for reproduction, so they don't relate.
What is an example of a population with the ingredient for species? Would it be evolution?
All members of a species that dwell in the same region are referred to as a population. You are a member of your hometown's human population. A freshwater pond is home to a variety of species, including mallard ducks and cattail plants growing on the pond's border. Basically, a population is a collection of individuals of the same species that live in the same geographic region and interbreed. Many animals have several populations that are spread across a wide range of geographic locations.
Why would a cancer cell need to induce angiogenesis? 1.53
Answer:
Why is angiogenesis important in cancer? Angiogenesis plays a critical role in the growth of cancer because solid tumors need a blood supply if they are to grow beyond a few millimeters in size. Tumors can actually cause this blood supply to form by giving off chemical signals that stimulate angiogenesis.
What that determines if a cell is eukaryotic. *
True or false? Prokaryotic cells are significantly smaller then eukaryotic cells.
Answer: False
Answer: Cell Size. At 0.1–5.0 µm in diameter, prokaryotic cells are significantly smaller than eukaryotic cells, which have diameters ranging from 10–100 µm (Figure 3.7). The small size of prokaryotes allows ions and organic molecules that enter them to quickly spread to other parts of the cell.

We can confirm that on the islands, Charles Darwin observed species similar to mainland South American species and to those found on the other islands.
What did Darwin notice about these species?Darwin noticed that each of these species were very similar, but possessed slightly different traits. These traits seem to perfectly fit the needs of each species for their specific island, leading to his creating the theory of evolution through natural selection.
Therefore, we can confirm that on the islands, Charles Darwin observed species similar to mainland South American species and to those found on the other islands.

Sally made a diagram to show one way that Earth's systems interact near a volcano
1. Identify the process that sally is moldering in her diagram
2. Explain how the individual parts shown in the model come together to form a cycle
The process that Sally is modeling in her diagram is the "Role of Volcanoes in the Earth's Systems". This particular system is called "the Cycle of Rock and Soil formation"
How do the individual parts of the model form the cycle?The cycle of soil formation starts with the production of molten magma by the volcano.
The magma solidifies and cools, then they are transported, deposited and go through lithification.
After lithification, they become sedimentary rocks, and then through exposure to pressure, they become metamorphic rocks.
Over the years, as more and more layers are deposited onto the metamorphic rocks, pressure and heat build up creating molten magma.
The magma creates igneous rocks which after many years may be produced again as molten magma through an active volcano.
