what can you infer about carbon dioxide from the fact that your body needs to breathe it out?

Answers

Answer:

You can infer that carbon dioxide is the chemical you breathe out

Explanation:

From prior knowledge we know that we breathe in Oxygen, so with this information given we can infer that.

[Hope this helped!]

Carbon dioxide is released by the body that needs to breathe it out, so it can be harmful if it builds up in the bloodstream.

What is carbon dioxide?

Respiration is the process through which an organism takes in gases and exhales them into the environment. Due to food digestion and oxygen inhalation, the organism's body exhales carbon dioxide back into the environment.

Food molecules are broken down into energy, water, and carbon dioxide during cellular respiration. In the presence of oxygen, cells respire, which involves a number of chemical processes.

Krebs cycle, phosphorylation cycle, and citric acid cycle are daily cycles. Glucose breaks down into carbon dioxide, water, and ATP when coupled with oxygen.

Therefore, because carbon dioxide must be exhaled by the body, its accumulation in the bloodstream can be dangerous.

100 percent

0 percent


25 percent


50 percent

Answers

Answer:

1) 50 percent

2) 50 percent

Explanation:

The dominant traits are those that are expressed phenotypically, whereas recessive traits are masked by the dominant traits.

The percent of offspring having dimples are 50 percent. The percent of offspring will be roan and expressing both the colors will be 100%.

The dimples are the traits, which are expressed phenotypically.

Let the alleles for the heterozygous parent with dimples be Dd. The other parent not having dimples will have the genotype dd.

The combination between the Dd and dd will result in:

Dd, Dd - heterozygous combination of alleles

dd, dd - purebred for the alleles

Similarly, the genotype of the hair color of the horse is white  and black .

The cross between the parental genotype will result in 100% heterozygous offspring with genotype [tex]\text {C}_w \text{C}_b[/tex]

The result will be due to codominance, in which both the characters of the parent will be expressed in the offspring such that the horse will have black and white colors.  

Therefore, the answers will be 50% and 100%.

A covalent bond has been defined as chemical bond that includes the sharing of the electron pair between the atoms.The pair of each electrons has been know as the bonding pairs and the stable balance of attractive and repulsive forces in between atoms.

The properties of covalent bond has the covalent compounds have low melting points and boiling points and generally the covalent compounds does not contain the electricity. The covalent compounds are  having lower enthalpies of the vaporization as well as fusion.

We have been talking about plant and animal cells over the past couple weeks. Plant cells have two organelles that animal cells do not contain. Name the two organelles that can be found in plant cells but not in animal cells and describe what each of those organelles do. Please answer in at least 5 complete sentences!​

Answers

Answer:

plant cells have chloroplasts and a cell wall. (they also have one large central vacuole.)

Explanation: Chloroplasts are found only in plant cells. Chloroplasts convert energy from the sun into sugar (glucose). The chloroplast is also where photosythesis happens in the plant cell. The cell wall is also only found in a plant cell. The cell wall protects and mantains the shape of the cell. And you don't have to put this one but the central vacuole is just one big vacuole in a plant cell that stores mainly water and nutrients since plant cells require more water to function, whereas in animal cells they have multiple small vacuoles.

Describe surface tension in a group of bonded water molecules that form a ""bead of water""

Answers

Surface Tension: "The property of the surface of a liquid that allows it to resist an external force, due to the cohesive nature of its molecules." ... The cohesive forces between liquid molecules are responsible for the phenomenon known as surface tension.

When water's surface tension is higher than the surface's energy, it beads. Surface tension is a liquid's ability to resist an external force due to the cohesion of its water molecules.

What is surface tension?

When water is in a liquid state, the molecules have a tendency to bead up or form droplets because of the mutual attraction that exists between them. Surface tension is a property that is manifested in liquids as a result of this attraction.

The phenomenon known as surface tension takes place whenever the surface of a liquid comes into contact with another fluid (it can be a liquid as well). Most liquids have the tendency to obtain the smallest possible surface area. The top layer of the liquid has the characteristics of a flexible sheet.

Viruses are not classified within any of the three domain of life (Archaea, Bacteria, Eukarya). Instead, they are considered as complex molecules or particles rather than living organisms. Viruses are made up of genetic material (either DNA or RNA) surrounded by a protein coat. They lack cellular structures and cannot carry out metabolic processes on their own. Viruses require a host cell to replicate and reproduce.

In summary viruses are distinct from living organisms in that they do not fit within the traditional domains of life due to their lack of cellular structure and independent metabolic processes.
