Compare and contrast epithelial and muscle tissues.
PLEASE HELP ME!
Answer:
The cell structure is formed according to their function.
Explanation:
Form and function are related to each other in human cells because the cells structure is formed according to its function. epithelial tissue are the group of cells that act as coverings of the body and controlling the movement of materials across their surface whereas muscle tissues are group of cells that are responsible for the movement of the body. Both tissues has different structure which allows it to perform different function.

Light Reactions : ATP :: Calvin Cycle :
a. G3P
b. H2O
c. O2
d. H+
Answer:
a. G3P
Explanation:
Photosynthesis is the process by which plants synthesize their food from inorganic sources in the presence of light. The photosynthetic process occurs in two stages namely: light dependent stage (light reaction) and light independent stage (Calvin cycle).
The light stage primarily functions to synthesize ATP and NADPH products needed in the Calvin cycle to synthesize sugar (glucose). However, the CALVIN CYCLE produces a three-carbon compound called GLYCERALDEHYDE-3-PHOSPHATE (G-3-P) as one of the precursors of glucose.

Hypothesis: If the amount of protein is calculated in three different lipid levels of milk, then whole milk will have the highest level of protein. What is the independent variable in this experiment? Type of protein Amount of protein Amount of milk Type of milk
Answer:
Type of milk
Explanation:
Independent variable is the variable that the experimenter changes or manipulates in an experiment. It is the variable that causes the dependent variable to change.
In this experiment, the hypothesis, which shows the relationship between the independent and dependent variable is stated as follows: IF the amount of protein is calculated in three different lipid levels of milk, THEN whole milk will have the highest level of protein. This shows that the amount of protein is dependent on the TYPE OF MILK used, which is the independent variable.

Sometimes new ideas in science come from traditional methods people used in the past. What did researchers learn from terra preta? How is bio-char different from the traditional Amazonian method of creating terra preta?
Answer:
What did researchers learn from terra preta?... Because terra preta is loaded with so-called bio-char -- similar to charcoal -- it also can pull substantial amounts of carbon out of the increasing levels of carbon dioxide in the Earth's atmosphere, helping to prevent global warming.
How is bio-char different from the traditional Amazonian method of creating terra preta? Terra preta owes its characteristic black color to its weathered charcoal content, and was made by adding a mixture of charcoal, bone, broken pottery, compost and manure to the low fertility Amazonian soil. ... Terra preta soils were created by farming communities between 450 BCE and 950 CE..
The BBC's Unnatural Histories presented evidence that the Amazon rainforest, rather than being a pristine wilderness, has been shaped by man for at least 11,000 years through practices such as forest gardening and terra preta.
Terra preta is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Researchers have learned from terra preta that it contains a high level of carbon, along with nutrients such as nitrogen, phosphorus, and potassium.
What is terra preta soil?Terra preta, or "black earth," is a type of dark, fertile soil found in the Amazon rainforest that is believed to have been created by indigenous people thousands of years ago. Scientists have studied terra preta to understand its unique properties and how it was created. Terra preta is a type of anthropogenic soil, which means that it was created by human activity rather than natural processes. It is believed that the indigenous people of the Amazon region created terra preta by adding biochar to soil along with other organic materials such as bones, shells, and manure.
Hence, researchers have learned from terra preta that it contains a high level of carbon along with nutrients such as nitrogen, phosphorus, and potassium.

if the hawk were to removed from the food chain, which consumer would increase in population
Answer:
Everything from the hawk's diet
Explanation:
Mice, rats, shrews, without their main predator, the ecosystem would become unbalanced by the increasing overpopulation of rodents and most likely small snakes that are also on hawks' diet. Another consumer would probably be other animals that eat the hawks' diet. Without a competing consumer, the, let's say snake, population would grow larger.

A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
Answer:
Option D
Explanation:
The complete question is
A scientist performed an experiment during which she measured the energy transferred in each step of her experiment. The total quantity of energy transferred in all of the steps was less than the amount she measured at the beginning. What is the most likely explanation for this result?
a) Energy was destroyed during certain steps in the experiment.
b) The steps in the experiment required more energy than was available
c) The experiments created energy that was then used up at a faster rate.
d) Some energy was transformed into unwanted heat or sound that was not detected
Solution -
Option D is correct
While transfer of energy through any medium, some energy is lost in the form of heat and light. This loss of energy is not accounted at the beginning of the process and hence the initial energy loss was zero. With the succession of the process energy kept loosing and hence the final energy count was low at all steps.
