Chicken liver is placed into lemon juice for 10 minutes. What type of evidence of a chemical reaction would be expected to occur when H2O2 (hydrogen peroxide) were added?
A) a lot of bubbles within a few seconds
B) some bubbles within the first minute
C) very few to no bubbles
D) the liver will catch fire, explote and cause the school to evacuate.
Answer:
When hydrogen peroxide is added to a chicken liver sample exposed to lemon juice the chemical reaction will be slower and appear some bubbles within the first minute (option B).
Explanation:
The liver contains an enzyme called catalase, whose function is the degradation of hydrogen peroxide (H₂O₂), an intense reaction that produces gas and heat. The activity of this enzyme must occur at an appropriate pH, so changes in pH can affect the activity of catalase.
Under normal conditions, when a liver sample is exposed to H₂O₂, bubbles and foam appear in the sample as a result of the catalase reaction. When the chicken liver sample is subjected to the acidic lemon juice, the reaction will occur, but more slowly.This is because the activity of the catalase enzyme, present in the liver, continues to occur —although it decreases— and will form few bubbles over a longer period of time.
The other options are not correct because:
A. At a lower pH, the reaction will not form many bubbles.
C. Even if the reaction is minor, and produces very few enzymes, it will always occur.
D. Although the catalase/H2O2 reaction produces heat, it is impossible for the liver to catch fire and cause evacuation from the school, even less so with a reaction whose speed has been slowed down.

Which statements about kinetic energy are true? It's always transformed into potential energy. It's always associated with motion It can be transferred from one object or body to another. It's found only in objects moving in a straight line.
Answer:
It's always associated with motion
It can be transferred from one object or body to another
Explanation:
Kinetic energy is the energy due to motion of a body.
Moving objects possess kinetic energy which is resident in that body. As with other forms of energy, it can be transferred from one body to another. Kinetic energy can express itself as thermal energy, electrical energy, mechanical energy etc.. As a body moves, the kinetic energy is increases.Albinism is a recessive genetic condition in which a person lacks pigment that gives color to the skin. If the allele for albinism is represented as "a," and the functional allele is represented as "A," what will be the genotype of a person with albinism?
Answer:
The correct answer would be - "aa".
Explanation:
Albinism is an autosomal recessive genetic condition which means it will be expressed only if both alleles for the pigmentation are recessive. If a single copy of the dominant allele present with the recessive allele the expression of the recessive allele would be masked by it and skin will be pigmented however they will act as carriers of the condition.
There would be three condition or three allele combination:
AA - no recessive allele so no albinism
Aa - dominant allele with recessive allele which means carrier but pigmented skin
aa - both alleles are recessive so the albinism will be expressed.

Explain positive climate feedback and negative climate feedback
Climate feedbacks: processes that can either amplify or diminish the effects of climate forcings. A feedback that increases an initial warming is called a "positive feedback." A feedback that reduces an initial warming is a "negative feedback."
HOPE THIS HELPED <3
Answer:
Climate feedback: processes that can either amplify or diminish the effects of climate forcings.
Explanation:
A positive feedback accelerates a temperature rise, whereas a negative feedback decelerates it.
50N of force is applied to a kg box. What will the acceleration be
[tex]\huge\boxed{50\frac{m}{s^-2}}[/tex]
_____________________________________DATA:
Force = 50N
Mass of the Body = 1kg
Acceleration = ?
_____________________________________SOLUTION:By the second law of newton,
F = ma
Rearrange the equation,
a = [tex]\frac{F}{m}[/tex]
Substitute the variables in the equation,
a = [tex]\frac{50}{1}[/tex]
OR,
a = 50 m/s^2

An atom of element x has one more shell of electrons than an atom of beryllium, but It
has one less valence Electron than beryllium.Which element is element X
Answer:
Sodium
Explanation:
This would leave you with 3 shells of 2, 8, and 1. Since it has one more shell then the second shell has to be 8. Since the first shell can only contain up to 2 it must be 2/8. And since it has one less valence electron than beryllium it must be a config of 2/8 1, which is the electron config of Sodium, Element with Atomic number 11 and electron shell of 2/8 1.

Sodium

Explain how a compound microscope allows you to see magnified images.
Answer:
The classic compound microscope magnifies in two steps : first with an objective lens that produces an enlarged image of the object in a "real" image plane. This real image is then magnified by the ocular lens or eyepiece to produce the virtual image. Two convex lenses can form a microscope.
Explanation:
Answer:
it has multiple magnifying glasses in the scope.
Explanation:
A compound light microscope uses two lenses at the same time to view objects-the objective lens, which gathers light and magnifies the image of the object, and the ocular lens, which one looks through and which further magnifies the image. ... it also allows light to pass to the ocular lens.

Based on the diagram shown above the Glycolsis, briefly describe the first step of cellular respiration, emphasizing the location, raw materials needed and the end products.
Answer:
Glycolysis takes place in the cytosol which is part of the cytoplasm of the cell. Glucose is rearranged and phosphorylated to form F-1,6BP(fructose 16 bisphosphate which is very unstable) its splits into 2 phosphorylated 3C sugars (DHAP and G3P)(can interconvert) both form G3P to enter 3rd phase, G3P converted into pyruvate creates 4 ATP in total but has a net of 2 ATP and creates NADH. The raw materials needed are two molecules of NAD+ per glucose as well as 2 ATPs. Hope this helps!
