2. Animals use oxygen in the process of
make more CO2.
Answer:
Cellular Respiration
Explanation:
As animals breathe, they take in O2 (Oxygen) and exhale in CO2 (Carbon Dioxide). This process is called cellular respiration.
Animals use oxygen in the process of cellular respiration to make more carbon dioxide.
What is Cellular respiration?Cellular respiration may be defined as a type of chemical reaction that involves the breakdown of food in the cell with the release of energy in the form of ATP with the help of oxygen and releases carbon dioxide.
The process of cellular respiration is utilized for the derivation of energy by cells in order to accomplish metabolic activities. This process generally occurs in the animal's cells.
The main purpose of this process is to convert foodstuff molecules into the most usable form of chemical energy known as ATP.
It is opposite to the process of photosynthesis in plants that utilized the carbon dioxide from nature and convert it into glucose and oxygen.
Therefore, animals use oxygen in the process of cellular respiration to make more carbon dioxide.

A confounding variable is an outside variable beyond the control of the race teams and official. What are some confounding variables that could contribute to the speed of the tracks?
Answer:
rain and turns
Explanation:
There are various confounding variables that could contribute to the speed of the track, one of which is rain. Rain is something that the race teams and officials cannot control and affects the speed at which racecars can operate on a track. This is because the Rain wets the tracks which prevents the cars wheels from properly gripping the track and instead causes them to skid. Another confounding variable would be turns. A track that has more turns would drastically decrease the speed of the tracks as cars would need to slow down for each turn.

Cartoon and movie characters such as Wolverine, Mystique and Storm lead to the notion that genetic
mutations always cause profound changes in the phenotype of an organism. However, the lesson
over DNA and Genetics clearly shows that mutations may or may not have an effect. Which of the
following mutations would most likely NOT cause an effect in an organism? (A Codon chart has been
provided below to assist you)
Answer: A
Explanation:
A frameshift mutation is brought on by a single base insertion close to the beginning of the coding sequence.
What is Mutation?Codons are used to express genes in triplets, the insertion will alter the reading frame and provide a translation that is entirely different from the original. Consequently, this will have the greatest detrimental effect.
A mutation is a change to an organism's DNA sequence. Errors in DNA replication during cell division, exposure to mutagens, or viral infection can all cause mutations.
Somatic mutations (which happen in body cells) cannot be passed on to offspring, whereas germline mutations (which happen in eggs and sperm) can.
Therefore, A frameshift mutation is brought on by a single base insertion close to the beginning of the coding sequence.

During science class, Mauricio made sketches of the major organelles of the cell. Which of the following is his sketch of a mitochondrion?
Answer: B
Explanation: I did The test
During science class, Mauricio made sketches of the major organelles of the cell. The second sketch describes a mitochondrion. The correct option is B.
What are mitochondria?The “powerhouses” of the cell, mitochondria, break down fuel molecules and harvest energy during cellular respiration. Chloroplasts and mitochondria probably started as microorganisms that were swallowed by larger cells (the endosymbiont theory).
A mitochondrion is a membrane-containing cell organelle. It is the site of energy-producing metabolic processes and cellular respiration. The process happens inside mitochondria.
Thus, the link between cellular respiration and photosynthesis is that the reactant in photosynthesis is a byproduct of cellular respiration.
Therefore, the correct option is diagram B.

Colorblindness is a recessive trait that is passed along to human offspring. The
inability to differentiate between or see some colors is controlled by a gene that is
found on the X chromosome. Why are more males affected by colorblindness than
females?
Colorblindness is more often found in males because they have less of a need to
see color
Colorblindness is more often found in males because they receive only one Y
chromosome and therefore men always will have colorblindness because
females do not have a Y chromosome
Colorblindness doesn't occur more often in males it happens equally in both
male and females
Answer:
The answer is the second one.
Explanation:
The answer is the second one because males have one x chromosome and one y chromosome. Females have only two x chromosomes. B makes more sense because males are more likely to have to deal with se-linked siorders because of their lack of x chromosomes.

describes why competition is a constant pressure?
Answer:
The options are not given, here are the options gotten from another website.
A. Organisms produce more offspring than can survive
B. Organisms are taught to fight others of the same species
C. Organisms are taught to fight others of the same species
D. Multiple species fill the same niche and competition will always arise against other species
The correct option is D.
Multiple species fill the same niche and competition will always arise against other species.
Explanation:
This is because competition arises when different organisms living a niche compete for space or resources and this can be as a result of too much population in a niche and limited resources and space. Organisms tend to compete for survival which is the driving force of natural selection.
These u because as competition rises, species tend to develop traits which will help them to survive, adapt , reproduce and compete well in their environment an this result in survival of the fittest....that is those that can adapt well.

Answer:
amplitude, wavelength, frequency, and speed.
Explanation: Sound is a type of wave that moves through matter and then vibrates our eardrums so we can hear. Light is a special kind of wave that is made up of photons. You can drop a rock into a pond and see waves form in the water. We even use waves (microwaves) to cook our food really fast. Water waves are the focus of our Tsunamis and surf resources, but many other kinds of wave exist. These include sound waves, light waves, radio waves, microwaves and others. All kinds of waves have the same fundamental properties of reflection, refraction, diffraction and interference, and all waves have a wavelength, frequency, speed and amplitude.
