Answer:
The student should try moving the slide and turn the coarse knob to get more focus. Once the sudent has got more light, use the fine focus knob to see better.
If a student is not getting sufficient light while using a microscope, they should first check the microscope's light source and its intensity. Then, they should inspect the condenser's position and aperture, adjusting them if necessary. Lastly, they should ensure proper specimen preparation and slide placement for optimal illumination.
When using a microscope, a student who experiences poor lighting should start by looking at the microscope's light source. Checking and adjusting the light intensity as necessary. The condenser's location and aperture should then be examined. Light focussing and distribution can be considerably enhanced by adjusting the condenser's height and aperture.
The student should also check that the specimen was properly prepped and placed on the slide. Poor illumination might also result from improper specimen placement or inadequate specimen preparation. The student can improve the light for efficient microscopy by methodically addressing these aspects.

Which statement explains the effect of temperature on the rate of photosynthesis
Answer:As temperature increases, the rate of photosynthesis constantly increases.
Explanation:
Temperature rise is accompanied by an increase in photosynthesis. As the temperature increase, the rate of photosynthesis also increases.
What is the effect of temperature?
Temperature rise is accompanied by an increase in photosynthesis. The rate of photosynthesis is shown to decrease at a temperature increase of 45 degrees, indicating that this increase is not exponential.
The rate of photosynthesis rises with the temperature between 35 and 40 degrees, but it falls below 40 degrees.
This happens as a result of enzymes being inactive at high temperatures. When temperatures are high, enzyme structures change and the reaction cannot be catalyzed.
Therefore, As the temperature increase, the rate of photosynthesis also increases.

5. Which of the following is the best definition of the Krebs cycle?
a. The oxidation of pyruvic acid
b. The way cells produce CO2
c. A series of chemical reactions in which NADH is produced from the oxidation of pyruvic acid
d. A method of producing ATP by phosphorylating ADP
e. A series of chemical reactions in which ATP is produced from the oxidation of pyruvic acid.
Answer: E.
Explanation: the krebs cycle is a series of chemical reactions used by the body to produce energy, or ATP. it does this through the oxidation of pyruvic acid. for this reason, the krebs cycle is also called the citric acid cycle!
A series of chemical reactions in which ATP is produced from the oxidation of pyruvic acid. So, the correct option is (E).
What is Krebs cycle?The citric acid cycle is also known as the Krebs cycle or TCA cycle. It is defined as a series of chemical reactions to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats and proteins.
The main function of the Krebs cycle is to produce energy, which is stored and transported in the form of ATP or GTP. The cycle is also central to other biosynthetic reactions where the intermediates produced are needed to make other molecules, such as amino acids, nucleotide bases, and cholesterol.
The Krebs cycle also consumes pyruvate which produces three things:
1. Carbon dioxide
2. A small amount of ATP
3. Two types of reductant molecules called NADH and FADH.
Thus, a series of chemical reactions in which ATP is produced from the oxidation of pyruvic acid. So, the correct option is (E).

Which star has an temperature of 10,000 K and a Luminosity of 10^2
Answer:
i think White Dwarf
Explanation:
We are given that the star has a temperature of 10,000 K and a luminosity of 10^2. According to the HR diagram, a star with the surface temperature of 10,000 K would be a white dwarf and if the star were on the main sequence, then it would have a luminosity nearly 100 times more than that of the sun. However since the actual luminosity is 10,000 times smaller than this, this star must be a white dwarf since it has 10,000 K and 100 aka 10^2 luminosity

The kidneys filter the blood by creating urine. The blood has to travel through these tissue cells to get into the kidney. There are lots of elastic tubes that the soon to be urine travels through while being filtered. The kidneys rely on blood pressure from the heart to move the liquid so lack muscle tissue. The kidneys do not control when you urinate as they simply pass the urine in to your bladder. Explain why the kidneys have each tissue listed below or why they don’t have each tissue.
Muscle Tissue :
Epithelial Tissue :
Nervous Tissue :
Connective Tissue :
Answer:
Muscle Tissue : The kidneys rely on blood pressure to move, since they lack muscle tissue.
Epithelial Tissue : The kidneys contain simple cuboidal epithelial tissue, which secretes and absorbs. Thus absorbing toxins from blood to be turned to urine.
Nervous Tissue : Kidneys to not contain nervous tissue due to the fact that they do not control when you urinate, but rather simply just pass the urine to the bladder.
Connective Tissue : Kidneys do contain Connective Tissue, called renal fascia, in order to keep the many elastic tubes in place, and a capsule of renal fascia closely envelopes each kidney to protect, and provide support for each kidney inside.

An adventure company that takes divers and tourists on glass-bottomed boat tours of a coral reef ecosystem has noticed changes in the ecosystem in recent years what are the changes and what could be causing them?
As we get closer to the coral reef, there are going to be several things we notice. The first thing we notice will be the large number of coral that seem to have lost their color, turning bright white. In addition, if we are in Florida, we may see something called the stony coral tissue loss disease. This disease has been of great concern in recent years in Floridian waters. Looking at these two changes, we can see that both are from the impact of climate change. As the water warms, the stress on the coral reaches a high point and they start to bleach and become more susceptible to several diseases.

Jaden tells David that she knows that she also could stand to lose about 45 pounds, which she knows will also help increase her energy level. She was wondering if David had any tips on making healthy food choices. What might David tell Jaden?
Given what we know about the nutritional facts of each food type, we can confirm that David may tell Jaden to focus her diet on proteins, vegetables, and white meat if necessary while avoiding sources of fat.
Jaden should attempt to focus on creating a diet based on protein sources like whole eggs. Around this protein source, she may add vegetables or white meat. This is mostly to avoid eating saturated fats which are almost immediately stored by the body and thus will prevent weight loss.
Not all fats are bad, some examples of nonsaturated fats to include are:

Thus, although it is evolving by all the other forces, the evolution of human hair color is not being driven by the process of natural selection.
What is natural selection?Natural selection is the method by which a species adapts to its surroundings. Natural selection causes evolution when individuals with particular traits have a better chance of surviving than those who are not able to adjust to the changes, and these traits are handed on to succeeding generations.
Better-adapted organisms will live and procreate through a process called natural selection. This indicates that this mutant organism's favorable alleles are handed on to progeny. Natural selection over many generations causes evolution to take place.
Thus, despite being influenced by all other variables, natural selection is not the primary cause behind the development of human hair color.

What is recycling? How does it help in management of hazardous waste?
Answer:
Recycling is the process of converting waste materials into new materials and objects.It is an alternative to "conventional" waste disposal that can save material and help lower greenhouse gas emissions.
When hazardous wastes are recycled, less energy is needed to obtain raw materials and to manufacture products. When energy demand decreases, fewer fossil fuels are burned and less GHGs are emitted into the atmosphere, which can help lessen the impacts of climate change and decrease air pollution.
Answer:
The process of converting waste materials into reusable material is called recycling.When hazardous wastes are recycled, less energy is needed to obtain raw materials and to manufacture products. ... This means less need for hazardous waste landfills and incinerators, as well as a decrease in energy used for those systems, which leads to less pollution
