Cellular respiration uses oxygen to release the energy stored in food.
Explanation:
In breathing living organisms take oxygen and release the carbon dioxide it is similar to the aerobic respiration.
There are two types of respiration:
1. Aerobic respiration
2. Anaerobic respiration
Aerobic respiration
It is the breakdown of glucose molecule in the presence of oxygen to yield large amount of energy. Water and carbon dioxide are also produced as a byproduct.
Glucose + oxygen → carbon dioxide + water + 38ATP
Anaerobic Respiration
It is the breakdown of glucose molecule in the absence of oxygen and produce small amount of energy. Alcohol or lactic acid and carbon dioxide are also produced as byproducts.
Glucose→ lactic acid/alcohol + 2ATP + carbon dioxide!
Organ systems maintain which of the following at
just the right
levels to support life processes?
a.) pH
b.) Carcinogens
C.) Temperature and pH
d.) Carcinogens and pH
Answer:
C.) Temperature and pH
Explanation:
Organ systems maintain the right temperature and pH levels to support life processes.
This is known as internal regulation or homeostasis.
Processes that support life requires some amount of fairly constant conditions for optimum level of metabolism to be attained. When the conditions are poor or in excess, reactions can greatly suffer. The ability of complex organism to maintain the right levels to support life processes is called homeostasis. pH and temperature are very important to all living organisms.Answer:

As the average kinetic energy of the particles in a gas increases, which of the following
occurs? (1 point)
The temperature of the gas increases.
The temperature of the gas decreases.
The number of particles increases.
The number of particles decreases.
Answer:
Amontons’s law. If the temperature is increased, the average speed and kinetic energy of the gas molecules increase. If the volume is held constant, the increased speed of the gas molecules results in more frequent and more forceful collisions with the walls of the container, therefore increasing the pressure

The liquid is a pure substance because it is made up of elements
The liquid is an impure substance because it is inside a thermometer.
The liquid is a pure substance because it is made up of mixtures.
Answer:
b
Explanation:
DID IT
Mercury is used in thermometers to estimate temperatures. Liquid mercury composed of Hg atoms is a pure substance that consists of single elements. Thus, option B is correct.
What are pure substances?Pure substances are chemicals that are matter and have been known to have distinct chemical properties because of their constant and definite composition. The physical methods of separation can not be used to separate the pure substances.
The liquid mercury is a pure substance as it has been composed of only one type of elemental atom Hg. All of its composition has been carrying the Hg atoms uniformly that possess and exhibit the same chemical and physical characteristics.
Therefore, option B. the liquid mercury is a pure substance as it is made of the same type of element.

.Which of the following lists contains only arthropods?
A
annelids, insects, myriapods CADA STAVI819 UAB
B.
arachnids, crustaceans, myriapods
С
crustaceans, insects. molluscs
D insects, myriapods, nematodes
Answer:
Arachnids, crustaceans, myriapods.
Explanation:
Arthropods are animals that form the phylum Euarthropoda. This phylum includes the arachnids, crustaceans, myriapods, and insects. The defining characteristic for an animal to be considered an arthropod is that it has to have an exoskeleton, meaning that the skeleton of the animal is acting as a shell to the body, covering it from the outside.
At present, all of the species of arthropods are small in size, though in the distant past there were speciemens that can be considered as medium-sized or even large. The exoskeleton has its advantages and disadvantages. An advantage is that it is very hard and it covers fully the internal organs, thus protecting them. A disadvantage is that it limits the size to which these animals can grow as the exoskeleton cannot support the weight of the body after certain point.

When a substance is added to meat, amino acids are produced.
What is this substance?
A) a hormone
B) an enzyme
C) an oil
D) water
The answer is B an enzyme ！
Answer:
[tex]\boxed {\boxed {\sf Enzymes}}[/tex]
Explanation:
Meat is a good source of protein because it is the main component. Hormones, oil, and water won't really produce a substance when added to meat. Enzymes break down different substances. The right enzyme can break down proteins. The monomer, or building block, of protein is an amino acid. Therefore, when a protein is broken down, amino acids are produces.
So, from the information above, we can assume that the substance is an enzyme. Enzymes break down meat/protein into amino acids.
There was a nearly intact fossil of a hadrosaur called Dakota. How did this find change our knowledge of the hadrosaur? List three specific ways.
Answer: Environment, skin coating, and perhaps seasonal migration.
Explanation: The hadrosaur has become an unmistakable species due to its unusual bill, and bipedal legs. However this new fossil could change many studies. First off, environmental hazards. Due to the amount of carnivorous fossils found in the Dakota area, finding a nearly intact fossil of any sort should be quite impossible. This brings paleontologists to believe hadrosaurs may have had some sort of defense against predators, which brings us to skin coating. To be found in such an arctic area must have meant it would be difficult for anything herbivorous to live in the area, unless feathers, or fur was involved. This could change every theory about the so called scaly beasts we refer to as dinosaurs. This brings us to our final topic, migration. Every winter if you were to go outside, it would be highly unlikely to hear birds. This is known as migration, a period when certain animals of multiple species, typically birds, move to warmer areas for the winter. Consider if the birds descending from dinosaurs theory was correct. This could in fact be how birds somehow get this preconceived notion to migrate. This, just as wild dogs are naturally aggressive, could be instinct.

How do human beings negatively affect the carbon cycle?
Human beings burn fossil fuels, which contribute carbon dioxide to the atmosphere.
Human beings conserve resources, which decrease resources for the carbon cycle.
Human beings mine resources, which increases the amount of oxygen available to the carbon cycle.
Human beings use carbon-based pencils, which decreases the amount of carbon dioxide in the atmosphere.
Eww
Answer:
Human activities have a tremendous impact on the carbon cycle. Burning fossil fuels, changing land use, and using limestone to make concrete all transfer significant quantities of carbon into the atmosphere. ... This extra carbon dioxide is lowering the ocean's pH, through a process called ocean acidification.

2.Which of the following is NOT an example of symbiosis? A. red blood cells containing malaria. B. vines using a tree for support C. nitrogen-fixing bacteria and the roots of legumes D. pigs feeding at a trough
Answer:
A. red blood cells containing malaria
Explanation:
Malaria is a disease-causing pathogen in humans. It is caused by species of the parasite Plasmodium sp., which is transmitted as sporozoites by the Anopheles mosquito upon biting the host. These travel through the bloodstream to the liver where they mature into merozoites. These reenter the bloodstream and mature into trophozoites and schizonts that produce more merozoites.
When they multiply within the red blood cell, they burst the red blood cell open, and go on to infect other cells. This infection's symptoms are cyclic and include high fever, chills and other flu-like symptoms.
Malaria is a deadly illness, causing harm to its hosts, and in many cases death. Thus, this cannot be defined as symbiosis, which is typically beneficial to both organisms.

If an individual has the genotype Bb, what alleles can it pass on to its
offspring?
A. Only B
B. Neither B norb
C. Either B or b
D. Only b
If a person possesses the genotype Bb, either the B or the b alleles can be passed on to their progeny. So, the correct option is C.
What is Genotype?An organism's genotype is made up of all of its genetic components. The alleles or variations that an individual carries inside a specific gene or genetic region are also referred to as the genotype.
The term "genotype" relates to an organism's whole gene pool, or, in other words, the genetic make-up of that creature. The phrase can also be used to describe to the alleles, or different forms of a gene, that an organism carries in a more specific meaning. Symbols can be used to symbolise it. For illustration, BB, Bb, and bb could be used to denote a certain gene variant.
If a person has the genotype Bb, as in the example above, then either the B or the b alleles can indeed be passed on to their progeny.
Therefore, the correct option is C.

FOR THE SECOND TIME-----Ughhh can someone answer this dang biology question I cant!!!!! I will mark you brainliest!!Referring to the graph, what phases together would account for approximately 25% of the time spent from a cell in the cell cycle?
A) M phase and S phase
B) S phase and M phase
C) G1 phase and M phase
D) G2 phase and M phase
Answer:
D. G2 phase and M phase
Explanation:
If we are looking for what takes up 25% of the graph, that would be the last option. If you look at G1, it takes up about 50%. So, G1 phase and M phase would take up more than that, and we want 25% not 50+. The M phase and S phase would take up about a third, so no. The G2 phase and M phase takes up roughly 25% or, it's the closest to this.

Homeostasis is maintained by which of the following organ systems in humans?
A. Multiple organ systems working together
B. The muscular system
C. The endocrine system
D. The nervous system
A. Multiple organ systems working together
Explanation:
All of the organ systems work together to maintain homeostasis in humans because each system does something different. For example, the circulatory system delivers oxygen rich blood to the bones and the bones create new blood cells. When one thing is wrong with one system, it affects all of the systems, like a disease. Another example of this would be the central nervous systems and endocrine working together to coordinate messages to the brain about the body's state while resting and exercising to maintain homeostasis.

Why do heart cells have different characteristics than skin cells???
Heart cells have different DNA than skin cells.
Heart cells reproduce by mitosis.
Heart cells express different genes than skin cells.
Heart cells reproduce by cell differentiation.
Answer:
Heart cells express different genes than skin cells
Explanation:
Cells contain instructions for their gene expression within stretches of DNA called genes, which is expressed and translated into protein.
Somatic cells are cells which contain the organism's chromosome number. They contain the entire karotype- and divide/ replicate through mitosis. In several stages of mitosis, DNA becomes condensed, is unwound and replicated, then packaged into two identical daughter cells.
All somatic cells start out undifferentiated (as stem cells). AFter the process of differentiation, they undergo changes in gene expression to become specific cell types, through processes like methylation and gain maturity.
11. Tom broke his leg. He was in a cast for six weeks. After his cast was
removed he had a hard time walking - WHY? *
Answer:
what-
Explanation:
Answer:
Well, the reason is because those muscles that he was once using every day, were suddenly on break and were not being used for the entire 6 weeks. Leading him to having some trouble walking.
Explanation:
When you don't use your muscles, they start to kind of chill out and get weaker in this case. So when you break your leg, and the doctor tells you not to put pressure on it, it is so that the bone can heal. But while your bone heals, the muscles in your leg are not able to move or do very much of anything because you can't put any pressure on them. So that is why when you take the cast off, you have to ease back into the regular motion in your leg that you had before.
