Explanation:
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 of the following is an example of homeostasis?
Humans shiver when it is very cold.
We cover ourselves with a blanket when it is cold.
We take a shower to keep the body temperature low.
An air conditioner keeps the body at a normal temperature.
i think its A, B, or C
Answer:
Humans shiver when it is very cold.
Explanation:
"Homeostasis" is the ability of the body to regulate itself in order to maintain a steady state. This includes mechanisms that allow automatic adjustment when the need for it arises. Covering ourselves with a blanket, taking a shower and turning on the air-conditioner are "not self-regulated" activities because they are done "intentionally" by the person. It is only "shivering" that shows the body's regulation of heat.
When the environment is cold, the skeletal muscles of the body respond by rapidly contracting and relaxing. This is what you call as "shivering." It produces heat through "respiration." Thus, it helps increase the body temperature.

A student makes the analogy that the cardiovascular system is like a highway. Why is this a good analogy? Blood is made of many different kinds of cells. The heart pumps blood through the veins. The heart is centralized in the body. Blood transports materials to and from different parts of the body.
Answer:
Explanation:
cardiovascular system is the circulatory system, it permits the circulation of blood and allows for transport of nutrients such as amino acids and electrolytes, oxygen and carbon dioxide gases, hormones, and blood cells in the body. It also helps the body to provide nourishment and fight against diseases and maintain homeostasis.
It is consider an high way because of its function. An high way allows for free passage, with often time no obstruction this is what cardiovascular system does they allow for movement of blood and essential nutrient in the body system for effective function of our body.

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.50N of force is applied to a kg box.

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.
Answer:
Sodium
Explanation:
In what way is binary fission different from mitosis?
Binary fission is asexual reproduction where singled cell organisms copies of themselves. Mitosis is cell division that a cell and results in two newly formed cells that are identical. Binary fission is making copies of a cell, and mitosis is splitting a cell into two new indetical new ones.
Answer:
Explanation:
Mitosis is a type of cell division that takes place among non-sex cells (somatic cells). This type of cell replication is designed to increase the number of cells during the blastogenesis and embryogenesis of both animals and plants. The most distinct characteristic of the mitotic process is the production of two product cells (daughters) which are similar to each other as well as to their original cell (mother) in both quantitative and qualitative aspects
Binary fission has three types: simple, transverse, and longitudinal binary fission. Simple binary fission happens in amoebas wherein the division goes by any plane. Transverse binary fission happens among paramecium and planaria wherein the cytoplasmic division plane matches the specimen’s transverse axis. Longitudinal binary fission occurs in the euglena when the plane matches the longitudinal alignment.

Explanation:
describe the movement of material during active transport
Active transport is the transport of molecules from the region of lower concentration to the region of higher concentration against the concentration gradient.
_____________________________________Requirement of Energy:Energy is required in this type of movement which is provided in the currency of energy i.e. ATP
_________________________________________________________
Q. Why is Energy Required?
A. Energy is required in this type of movement, because the molecules are moving from less crowded region of the molecules to the more crowded region of the molecule, so the energy is required to get into the crowdy region the molecules require energy to kind of PUSH the molecules and get into that region.
_________________________________________________________
Q. Where does ATP come from?
A. Free energy obtained from hydrolysis of ATP is used for the movement of the solutes against the concentration gradient across the plasma. The transmembrane protein which is also called pump is used in this process, The transmembrane protein is the type of integral protein which provides gateways to permit the transport of specific substances across the membrane.
