Answer:
Replace the concentration descriptions with actual values
Explanation:
For results of this nature to mean much, they need to be able to be reproduced by a different experimenter. In order to be able to do that, the experimenter must be able to reproduce the salt concentrations. The graph would be more useful if it had the actual concentration values.
Answer:
Replace the concentration descriptions with actual values

explain why living organisms
contain more hydrogen atoms than any other
atorns yet 65% of a typical organism's mass is
Oxygen
Answer:
The living species comprise more number of hydrogen atoms in comparison to any other atoms, still 65 percent of the usual organism's mass is oxygen. The prime reason for this is that an atom of oxygen comprises sixteen times more mass in comparison to a hydrogen atom.please mark me as the brainliest thnx

How do enzymes help digestion?
Answer:
Enzymes are essential for healthy digestion.
Explanation:
There are three types of digestive enzymes depending on the type of food on which they act.
Lipases are those that digest fat. After its breakdown into fatty acids and glycerin, they are synthesized by the pancreas.
Proteases are the ones that break the peptide bonds of proteins, reducing them to organic monomers called amino acids. They originate in the stomach or pancreas.
The so-called amylases break down starches and complex sugars in the diet, by breaking the glucidic bonds, releasing mososaccharides (especially glucose). There are 3 types of amylases: ptyaline, pancreatic amylase, and duodenal amylase.
The benefits of these enzymes are:
- They help digestion and reduce the so-called "acidity".
- They reduce the feeling of bloating and gas.
- Improves the digestion of dairy products.
- Food allergies decrease due to good protein digestion.
- They improve the conditions of hiatus hernia and ulcers.
What is the role of each of the following in the carbon cycle? Include an example of each. a) Producer b) Primary consumer c) Decomposer
Answer:
Explanation:
Producer- plants like grass
primary consumer- herbivore , like a rabbits
decomposer - earthworms and maggots.
Producer consumes carbon whereas primary consumer and decomposers consumes as well as releases carbon.
Producer takes inside carbon in the form of carbondioxide gas which is used as a raw material in the process of photosynthesis while on the other hand, primary consumer consumes carbon in the form of starch and cellulose by eating producers and releases carbon in the form of carbondioxide in the atmosphere. Decomposer feeds on carbon that is present in the dead bodies of animals and plants which also releases carbon in the form of respiration so we can conclude that producers take inside carbon whereas primary consumers and decomposer releases carbon in the atmosphere.

Describe how incomplete dominance and codominance, two non-mendelian traits, are different from each other.
Answer:
Incomplete dominance occurs when the dominant allele did not completely mask the effect of the recessive allele so that, the recessive allele could manifest some of its traits.Therefore the offspring exhibits some phenotype which reflects the blends of the two traits.( four O'clock flower)
However, in co-dominance(e.g AB blood group) none of the dominant allele is completely dominant over one another.That is the two allele of the same gene are present in the same offspring.Therefore the alleles shows their dominating effects, in the offspring, but no blend of the alleles as in the incomplete allele.

Why are desert landscapes jagged and rocky? There is little chemical weathering to round the landscape. Lack of vegetation causes sinkholes between rock formations. The evaporation process creates angular surfaces.
Answer:
A. There is little chemical weathering to round the landscape.
Explanation:
There is little chemical weathering to round the landscape in desert, primarily because there is significantly small to none water available to cause any weathering of the rocks or other structures in deserts.
Name one disadvantage of light microscopes
Answer:
We can't examin the specimen in tbe absence of lght. We can not study the internal structures.
Explanation:
Answer:
Light microscopes do not magnify at the same level as other options.
The typical light microscope cannot magnify as closely as an electron microscope when looking at some of the world’s smallest structures. Most models are capped at 2,000 times or thereabouts, with some entry-level models offering significantly less to the user. Because the relatively long wavelength of light decreases the ability of the equipment to magnify in the small focus lens, you may not always see everything that is going on with a slide when choosing this option.

Can someone please help
Answer:
P = 0.79.
Explanation:
To solve this, we need to understand the Hardy-Weinburg equation and what each variable is. P is usually used for the dominant trait classification (in this case, it would be long legs) and Q is usually used for the recessive trait classification (in this case, it would be short legs).
Therefore, we know that the values have to add up to 1 and that Q is recessive and P is dominant. So, if we begin applications, we can learn that to equal 1, we must use numbers less than 1 to accomplish this.
If 21 of a 100-person population have short legs, then ideally, 79 people would have long legs (the dominant trait). So, we know that 0.21 as q and 0.79 as p would equal 1 if you just added p and q together. Therefore, we can know that q is 0.21 and p is 0.79.
To prove this, we can insert these values into the equation:
[tex]0.79^{2} + 2(0.79*0.21) + 0.21^{2} =1[/tex]
[tex]0.6241 + 0.3318 + 0.0441 =1[/tex]
[tex]1=1[/tex]

Answer:
La respuesta correcta es "a. arterias, b. venas; y c. capilares".
Explanation:
Los vasos sanguíneos son una serie de conductos a través de los cuales el cuerpo transporta la sangre, asegurando que todas las células del cuerpo tenga acceso a oxígeno, elemento necesario para la respiración celular. Hay tres tipos de vasos sanguíneos: arterias, venas y capilares. Las arterias llevan la sangre del corazón a los órganos, las venas transportan la sangre de los órganos al corazón y los capilares son vasos muy pequeñitos que llegan a las partes más pequeñas del cuerpo.

write any three differences between metals and non-metals?
Answer:
Differences between metals and non-metals
Explanation:
Metals are elements that have luster.
Non-metals are elements that do not have luster. They are dull.
There are one to three electrons in the outer shell of the metals.
There are four to eight electrons in the outer shell of the non-metals.
Metals are a good conductor of heat and electricity.
Non-metals are the bad conductors of heat and electricity.
Metals are malleable, ductile, and sonorous.
Non-metals are brittle, non-ductile, and non-sonorous.
It was once thought that decaying meat turns into maggots. Careful experimentation by scientist demonstrated that maggots actually come from fly eggs and not meat. These experiments illustrate that the new individual results only from reproduction and development
Answer:
True
Explanation:
Aristotle initially thought that life arose spontaneously and he backed this up by showing that a lump of meat left uncovered in a glass jar spontaneously produced maggots.
The spontaneous generation theory was later disproved by another scientist, Francesco Redi. He showed that a covered jar containing a lump of meat will not spontaneously produce maggots unless flies are allowed to perch and lay their eggs on the meat. The eggs of the flies give rise to the maggots and not the meat.
It thus showed that new life does not arise spontaneously but rather through development and reproduction.
which of the following process is needed to build molecules for body needs catabolism , anabolism , metabolism ,
all the above
Answer:
Anabolism
Explanation:
metabolism is the breakdown of complex molecules.
catabolism is the breaking down or building up of complex molecules in the body. Metabolism and Anabolism are both subsets of catabolism.
a) The important factor in osmosis is not the number of molecules. Instead, it is the number of particles in a given volume of solution. For example, one glucose molecule dissolved in water yields one particle, but one NaCl molecule can yield two ions: Na+ and Cl-. Water moves osmotically in response to the total concentration of particles in the solution.
If there is a 10% glucose solution on one side of a semipermeable membrane and 5% salt solution on the other side, what will most likely happen to the flow of water? (1 point)
