Lion vs elephant digestion lab

Answers

Answer:

In lions, digestion takes place in the stomach while in elephant, digestion takes place in cecum.

Explanation:

Lion eats meat which needs a powerful digestion of strong juices which helps in the breakdown of food. There are four compartments of the stomach of lion that are rumen, reticulum, omasum, and abomasum. These chambers have microorganisms which helps in the breakdown of food materials while in the elephant, the stomach primarily functions in the storage of food and digestion takes place in the cecum that is connected to the large intestine.

Hydrogen peroxide is a substance that is produced as a byproduct of many cell processes. However, hydrogen peroxide is toxic to cells. In fact, if cells are unable to break down hydrogen peroxide, they become poisoned and die.

The chemical reaction for the breakdown of hydrogen peroxide is shown below.


What role does catalase play in this reaction?

Answers

Answer:

In the reaction of decomposition of hydrogen peroxide (H₂O₂), catalase is the enzyme responsible for catalyzing this reaction.

Explanation:

Catalase is an oxide-reductase enzyme whose substrate is H₂O₂, a potentially harmful by-product of metabolism.

The reaction that is mediated by catalase is:

                           H₂O₂ ------catalase--- → 2H₂O + O₂

where catalase is the enzyme that breaks the bond of the additional oxygen in the molecule to obtain H₂O and free O₂.

People with catalase deficiency may experience disorders and diseases due to the accumulation of H₂O₂ in the body.

If you wanted to stay 20 feet below the surface of the water, what kind of buoyancy would you need to have? Positive, Negative or Neutral?

Answers

Answer:

It depends what kind of water.

Explanation:

Salt water:

You would need a negative buoyancy.

Fresh water:

You would need a neutral buoyancy.

Please let me know if I am wrong!

Buoyancy is the tendency of an object to float at the upper surface of the fluid due to upwards force. If the diver wants to stay below the water surface then they will need negative buoyancy.

What is buoyancy?

Buoyancy has been defined by the upthrust experienced by an object in a fluid or liquid medium. It is a force that opposes or counters the weight of the object. Buoyancy can be positive, neutral, or negative. Positive buoyancy makes object float.

A negative buoyancy occurs when the object has more mass and density than the fluid so that the applied force makes them sink. So, if a person wants to stay 20 feet below the surface of the water then negative buoyancy has to take place.

Therefore, negative buoyancy will make a person stay at the bottom of the water.

What does it mean to have a hypotonic solution?

Answers

Answer:

A hypotonic solution has a lower concentration of solutes than another solution. In biology, a solution outside of a cell is called hypotonic if it has a lower concentration of solutes relative to the cytosol. Due to osmotic pressure, water diffuses into the cell, and the cell often appears turgid, or bloated.

Answer:

alright so there's 3 kinds of solutions!

hypotonic, isotonic and hypertonic

basically a cell is in a hypotonic

solution if the concentration of water

inside the cell is LOWER than the concentration

outside the cell. Water diffuses from high

to low. Water enters the cell.

Which describes sexual reproduction, and not asexual reproduction?

Answers

Answer:

One characteristic that describes sexual reproduction and that is not present in asexual reproduction is the combination of genetic information from two parents.

Explanation:

Sexual reproduction involves the participation of two individuals, whose genetic material is contributed and when they unite they give birth to a new individual, through the process of fertilization.

Individuals who reproduce sexually have the ability to form cells with half of their genetic charge, called gametes. The union of these cells forms the zygote, from which a new individual develops.

In asexual reproduction, a single individual is responsible for the reproductive process, which occurs by

Gemination. Bipartition Fragmentation. Parthenogenesis. Sporulation or sporogenesis.

Each one of these processes represents a different type of reproduction than the one that occurs sexually.

In which situation is energy released by a plant?


when oxygen is released into the air

before energy is stored in sugar molecules

when plants break down sugar molecules

when sugar and oxygen are made

Answers

Answer:

When sugar and oxygen are made

Explanation:

Through photosynthesis certain energy’s convert solar energy into chemical energy. Photosynthesis is the process used by plants to harness energy from sunlight. It is an endothermic (takes in heat) chemical process that uses sunlight to turn carbon dioxide into sugars. The sugars are used by the cell as energy, and to build other kinds of molecules.

Answer: D

Explain:
For example, an unopened soda in a bottle has a uniform composition and is a homogeneous mixture. Once you open the bottle, bubbles appear in the liquid. The bubbles from carbonation are gasses, while the majority of the soda is liquid. An opened can of soda is an example of a heterogeneous mixture.

Ms. Hendren has decided that she would like to grow some tomatoes and wants to know how much light will cause the plant to grow the largest tomatoes. She plants tomato seeds in 4 different pots and leaves one pot in the dark. She gives 6 hours of light a day to the second, 8 hours of light a day to the third, and 10 hours of light a day to the fourth. After 3 months she measures the size of the tomatoes grown. Match up each variable in the experiment. Group of answer choices Independent varible [ Choose ] Dependent variable [ Choose ] Control variable [ Choose ] Control group [ Choose ]

Answers

Answer:

The correct answer is -

Independent variable - the amount (time period) of light given to pots.

Dependent variable - size of tomatoes

Control variable - dark or absence of light

Control group - pot placed in the darkroom.

Explanation:

The independent variable is the variable that is changed or manipulated in particular research or study to see the effect of that variable on dependent variable. In this case, the amount of light each pot gets is the independent variable.

The dependent variable is the variable that depends on the change in the independent variable. The size of tomatoes is the dependent variable here.

The control variable is the variable that remains in standard condition or condition which can be used to compare with the effect of the independent variable. The absence of light on one of the tomato pot is the control variable.

The control group is the group of subjects did not get any treatment that experiment group receives. The pot which is placed in the dark room is control group here.

Answer:

Explanation:

The genotype of square A is Ee, square B is ee, square C is Ee, and square D is ee.

What are genotypes?

Genotypes are the genetic makeup or the complete set of genes that an individual organism possesses. They are responsible for determining an organism's physical and behavioral traits.

The genotype of an organism is encoded in its DNA, which consists of long sequences of nucleotides that code for specific proteins and other functional molecules. These nucleotide sequences are organized into genes, which are located on chromosomes in the nucleus of the cell.

Genotypes can be inherited from parents and passed down to offspring through sexual reproduction. However, mutations and genetic variations can also occur spontaneously, leading to changes in an individual's genotype.
