Which of the following describes a second class lever
1. The fulcrum is located between the effort force and the load.
2. The effort force is located between the fulcrum and the load force.
3. The load force is located between the effort force and the fulcrum.
Answer:
I think the answer might be number 2
In the second class lever, the load is between the effort force and the fulcrum. The correct option is 3.
What is a fulcrum?The term can refer to the juncture or assistance on which a lever rotates, as well as the focal point of a critical activity or situation.
The term "fulcrum point" in zoology refers to an anatomical structure that serves as point of support.
The load in second-class levers lies among both the effort and the fulcrum. A wheelbarrow is a prominent example, where the effort moves a great distances to lift a substantial load, with the axle and wheel acting as the fulcrum.
In a second-class lever, the effort is distributed over a large area in order to raise the load a short distance.
Thus, the correct option is 3.

A basketball with a mass of 0.60 kg is accelerated with a force of 10.8 N. If resisting forces are ignored, what is the acceleration of the basketball to the nearest m/s2?
Answer:
18 m/s^2 A newton is defined as kg*m/s^2 and you want to accelerate a mass in kg, getting a result of m/s^2. So what you need to do is cancel out the kg unit in the newtons. You can do that by dividing the newtons by kg. So let's do the math. 10.8 kg*m/s^2 / 0.60 kg = 18 m/s^2 So the ball has an acceleration of 18 m/s^2. Remember, look at the units you have and the units you desire. By doing so, the math operations become obvious.

You need to find out why the GBR water is inhibiting (stopping) photosynthesis in the algae. The three major parts of photosynthesis are PSI, PSII and the Calvin cycle. The database has provided 3 things that could be inhibiting photosynthesis: high sea temperatures, paraquat, and diuron.
Answer:
Explanation:
The question is not complete below is the remaining part of the question
Justify your choice by writing a hypothesis to explain how it has stopped the algae from making ATP, NADPH and sugars. You will be able to revise your hypothesis as you do more experiments
Explanation:
The hypothesis will be
High sea temperature inhibit Algae growth
Herbicides reduces algae photosynthesis rate
Algae respond to temperature differently some thrive at a low temperature, some at a moderate temperature but when the temperature is very high the rate of photosynthesis will reduce because they can not undergo the normal body physiological function as a result of harsh environment. In green plant at a very high temperature stomata closes to regulate water loss this prevent Carbon dioxide from coming in and photosynthesis rate reduces
Paraquat and Diuron are herbicide that prevent the growth of plants, when they are sprayed Algae is affected they die from immediate action of this chemical and their colour changes since chloroplast the green pigment is where light hit for photosynthesis to occur when the color changes the active site is affected photosynthesis can no longer occur.
Answer:
Diuron
Explanation:
Increasing the temperature only decreases the sugar, not the ATP and NADPH. I predict that Diuron will be inhibiting photosynthesis because photosynthesis as a whole should not work if Photosystem II is interfered with. Also, because Paraquat only lowers NADPH and sugar and not ATP, Diuron is the only choice left.

energy
B. Photosynthesis produces carbon dioxide, and cellular respiration
produces sugars.
C. Photosynthesis and cellular respiration occur in both plant and
animal cells.
D. Photosynthesis produces the oxygen required for cellular respiration.
Answer:
B is the correct answer.
A is incorrect because respiration is always occuring in animals and plants, therefore it means it does not require the presence of light. Photosynthesis does produce ATP, though.
Not C because photosynthesis does not occur in animals
Not D because they both are different processes. They don't really depend on each other, though they could occur at the same time.

Each strand of s DNA molecule contains nitrogenous bases that pair with other nitrogenous bases in very specific ways. A diagram of a section of DNA is shown. DNDA Strand 3' _|___|___|___|___|___|___|___|___|___|___|___|___|_ 5' T G T A G C T G C G C G T Which DNA strand is complementary to the one shown above?
Answer:
The complementary DNA strand, according to the nucleotide sequence of the other strand is 3' - A C A T C G A C G C G C A - 5'
Explanation:
Each strand of DNA is made up of specific sequences of the four nucleotides present in this molecule, adenine, thymine, cytosine and guanine.
In double-stranded DNA, one strand complements the other —according to the complementarity of nitrogenous bases— where a purine, adenine and guanine, are joined with a pyrimidine, thymine and cytosine, respectively:
Adenine is complemented with Thymine. Guanine is complemented with Cytosine.According to this, the complementarity of the strands is:
5' - T G T A G C T G C G C G T - 3'
3' - A C A T C G A C G C G C A - 5'
The DNA strands remain linked by hydrogen bonds between their nitrogenous bases, until such time as they must be separated for transcription.

They will be different from the reactants
Explanation:
Even though the new product is made up of the reactants, the product will have different properties.
Phenylalanine is required for the production of many bodily proteins, but none of your cells are capable of synthesizing this essential amino acid. What type of metabolic pathway must be responsible for providing phenylalanine to your cells? How would your diet effect the mount of Phenylalanine that is available?
Answer and explanation:
Phenylalanine is an amino acid that is very important for our bodies to function correctly but it isn't synthesized in our cells, so the only way to incorporate it is by having it in our diets, this is why phenylalanine is an essential amino acid.
Phenylalanine can be found in milk, eggs, chicken, and liver, among other foods known to be good protein sources. Given the fact that phenylalanine is an essential amino acid, the amount we ingest of it in our diet will directly impact on the availability of this amino acid in our body.
Phenylalanine is an amino acid and, as such, it will enter the metabolic pathway of protein catabolism, where it will be degraded to be fully usable for the body. Phenylalanine will be metabolized into acetoacetic acid and fumaric acid, and is the precursor of catecholamines such as epinephrine and norepinephrine, while also being part of the structure of several neuropeptides.

Why are glucose molecules able to dissolve in our blood but lipids are not? List the type of chemical bonds
Its an emergency
I need it right now
Answer:
Glucose is small (6 carbons) and dissolves easily in water because it has a number of polar OH groups attached to its carbons. Now lipids, they are constructed of long chains of carbon and hydrogen called fatty acids. These chains are not polar and lipids do not dissolve or mix well with water for this reason.
Explanation:
In this case the blood is not too much thicker than the water my friend XD.
Identify the structures a virus can contain.
Answer:
The simplest virions consist of two basic components: nucleic acid (single- or double-stranded RNA or DNA) and a protein coat, the capsid, which functions as a shell to protect the viral genome from nucleases and which during infection attaches the virion to specific receptors exposed on the prospective host cell.

PLEASE HELPPP I WILL GIVE BRAINLIEST What effect does starvation or suffocation have on the process of cellular respiration and how would this affect the organism as a whole. include these words: carbon dioxide, glucose, oxygen, water, ATP, reactant, product, food, fermentation, and anaerobic respiration. Please helppp
Answer:
Explanation:
This question seeks to test the knowledge of anaerobic respiration during the process of glycolysis. During intense exercise (or suffocation) the energy/ATP produced (for the short period of about 2 minutes) is as a result of the breakdown of glucose in the absence of oxygen (known as anaerobic glycolysis).
When an individual is fasting or experiencing starvation, the glycogen storage is quickly converted to glucose and then released into the body for cellular breakdown or respiration for the production of energy or ATP. Glycolysis leads to the formation of pyruvate; during suffocation/exercise, the pyruvate (serves as reactant) undergoes fermentation to either produce lactate in humans or ethanol and carbon dioxide in yeast cells (where lactate, ethanol and carbon dioxide serve as products).
Hence, starvation can be said to deplete glycogen storage while suffocation or anaerobic respiration (breathing in the absence of oxygen) causes the cellular breakdown of glucose (glycolysis) to be anaerobic. However, when the glycogen storage starts getting depleted, stored lipids starts getting converted to energy also in the presence of water in body.
It should be noted that the glucose (which is stored as glycogen) is synthesized/obtained from the food we eat.
