How can you identify the difference between a chemical and physical change and what are signs that a chemical change had occurred?
Answer:
The difference between a physical reaction and a chemical reaction is composition. In a chemical reaction, there is a change in the composition of the substances in question; in a physical change there is a difference in the appearance, smell, or simple display of a sample of matter without a change in composition.
If a female with blood type oo has children with a male with blood type ab, what are the possible blood types of their children?.
Answer:
50% with blood type A and 50% with blood type B
Explanation:
You can draw a punnet square and find that the possible combinations are AO, AO, BO, and BO. The presence of antigens on the blood cells make them type A,B or O. If antigens are put on O they can be made into a new blood type. For example if A mixes with O the fused blood will be of type A.
I hope this explaination helps you!
Only the O allele can be passed on to a child by a mother who has blood type O. A parent with blood group AB could give his kid or daughter either an A or a B gene. Blood type B or blood type A (O from the mother and A from the father) could be the blood type of the children of this couple (O from mother and B from father).
What is Blood group?According to the presence or absence of antibodies or hereditary antigenic compounds just on surface of red blood cells, blood is classified according to its type. Depending on the blood group system, these antigens could be proteins, carbohydrates, glycoproteins, or glycolipids.
The ABO system distinguishes 4 major blood types:
Blood group O - has no antigens, however both anti-A and anti-B antibodies in the plasma Blood group AB - has both A and B antigens, but no antibodies Blood group A - has A antigens just on red blood cells with anti-B antibodies in the plasma Blood group B - has B antigens with anti-A antibodies in the plasma.Thus, only the O allele can be passed on to a child by a mother who has blood type O. A parent with blood group AB could give his kid or daughter either an A or a B gene. Blood type B or blood type A (O from the mother and A from the father) could be the blood type of the children of this couple (O from mother and B from father).

The more collisions there are between gas molecules, the ______ air pressure will be.
... the higher air pressure will be.
The more collisions there are between gas molecules, the higher the air pressure will be.
What is Air pressure?Air pressure is the force exerted by the weight of air on any object in the atmosphere. The air around us is made up of tiny gas molecules that are constantly in motion and colliding with each other and with the surfaces around them. These collisions create a force that we experience as air pressure.
When there are more collisions between gas molecules, this means that there is a greater force being exerted on the surrounding surfaces, which translates to a higher air pressure. This can happen in a variety of situations, such as when the temperature increases, when there is more gas in a container, or when the volume of the container decreases.
For example, imagine a balloon filled with air. If you were to heat the balloon, the gas molecules inside would start moving faster and colliding more frequently, resulting in a higher air pressure inside the balloon. This can cause the balloon to expand or even burst if the pressure gets too high.
In summary, the more collisions there are between gas molecules, the higher the air pressure will be, and this can have a variety of effects on the surrounding environment.

what did Darwin notice about the different species of finches?
The finches differed from their ___ in South America. Different finches had different ___ habits and different ___ and shaped ___ that matches what they ___.
a. Ancestors
b. Hunting
c. Ate
d. Beaks
e. Sized
f. Eyes
g. Feeding
h. Saw
When Darwin first saw finches, they were often black, brown, or olive in hue, which caused him to describe them as “drab and uninteresting little birds.” Their beaks, which differ greatly in size, shape, and color, are their most distinctive feature. Thus, option A, C, D, G, E is correct.
What are the different feature of the Darwin finches?Darwin questioned why bird beaks on different islands had different shapes. Compared to its relatives, the ground finches, so-called cactus finches have longer, more pointed beaks.
Warbler finches have beaks that are both more pointed and narrower than both. They are better able to subsist on available food thanks to these adaptations.
The plumage and body size of the birds vary, but the beaks' size and shape—which are influenced by the foods the birds prefer and their areas of specialization—are the features that stand out the most.
Therefore, Darwin notice about the different species of finches.

why do plants need a larger vacuole, a cell wall
and chloroplasts and animal cells do not.
Answer:
This is the answer
Explanation:
Animals get sugar from the food they eat, they do not need chloroplasts: just mitochondria. Both plant and animal cells have vacuoles. The plant has the largest vacuole than animal cells because in plant cells the larger central vacuole performs two functions, one is to store water and the other is to help the plant remain upright. A plant cell contains a large, singular vacuole that is used for storage and maintaining the shape of the cell. Animals are motile but plants and stiff. Cell walls make plants stiff so they cannot move.Animals don't have cell walls so they can move. Photosynthesis takes place in chloroplasts; cell walls allow plants to have strong, upright structures; and vacuoles help regulate how cells handle water and storage of other molecules.

Explanation:
In the year 2000, specimens of caulerpa taxifolia,a green alga used in tropical aquariums, were found off the coast of california. Native to the indian ocean, c. Taxifolia is known for aggressive growth and an ability to compete with sea grasses. It is currently on an international list of invasive species. Which of the following best predicts the consequences of the introduction of c. Taxifolia to the california coast?.
The consequences of the introduction of c. Taxifolia to the coast of California is the disappearance of other algae species where C. taxifolia colonizes.
What are the impacts of C. taxifolia?This alga causes a marked decrease in biodiversity in the environments colonized by it. It was observed, in 1991, that it covered the beds of algae of Cymodocea nodosa and especially of Posidonia. Initially, the Posidonia seaweed bank seems to react positively to contact with the seaweed, increasing its production. Later, after being completely invaded, it shows signs of "stress" (leaf fall...) leading to a setback and then the total disappearance of the algae bank as well as the algae that grew together with the posidonias.
Whit this information, we can conclude that the consequences of the introduction of c. Taxifolia to the coast of California is the disappearance of other algae species where C. taxifolia colonizes.
