How are mechanical and chemical weathering similar?
A - Both break down rock
B - Both build up up landforms
C - Both only occur when water is present.
D - Both change the composition of the rock.
Answer: A - Both Break down rock
Explanation: Mechanical weathering preserves composition, weathering doesn't build landforms, and water doesn't need to be present for weathering to occur.

why might patients who go into remission get a different type of cancer?
Answer:
Remission can be partial or complete. In a complete remission, all signs and symptoms of cancer have disappeared. If you remain in complete remission for 5 years or more, some doctors may say that you are cured. Still, some cancer cells can remain in your body for many years after treatment.

The original source of new alleles, upon which selection operates, is mutation, a random event that occurs without regard to selectional value in the organism. Although many model organisms have been used to study mutational events in populations, some investigators have developed abiotic molecular models. Soll et al. (2006. Genetics 175: 267-275) examined one such model to study the relationship between both deleterious and advantageous mutations and population size in a ligase molecule composed of RNA (a ribozyme). Soll found that the smaller the population of molecules, the more likely it was that not only deleterious mutations but also advantageous mutations would disappear. Why would population size influence the survival of both types of mutations (deleterious and advantageous) in populations
Answer:
Sampling error may allow fixation of one form and the elimination of others in a small population.
Explanation:
It can be seen that in case of a small population size, there are high chances of the elimination or the fixation of the allele in the population when compared to the large population size. Also sampling errors are found in case of small population size that leads to the enhancement of the chances for fixation and also for the elimination of the allele. This large size population doe not have much effect. The random fixation of the either selective allele or the elimination of the disadvantageous allele occurs due to the genetic drift.
SO in order for the population size influenced the survival of both types of mutations , the sampling error may be allowed for the fixation of one of the form and the elimination of the other forms in the small population size.
Which event might disrupt a stable ecosystem?
A
Green plants use chlorophyll to produce food.
B
An invasive species enters the environment.
Consumers eat producers.
D
Predators kill prey.
Answer:
An invasive species enters the environment.
Explanation:
All other answers already naturally happen in an environment so they are stable. But if an invasive species enters, the ecosystem will be less stable because invasive species dominate ecosystems which isn't natural to the animals that live there. So for example, if someone introduced an invasive species to the ecosystem, it can cause many changes like if it was a predator, there'll be less primary consumers (the animals that eat plants) because the invasive species isn't natural to them.
Answer:
B
Explanation:
An invasive species enters the environment is the correct answer.
how can we differentiate between strong and weak acids using indicator?
Answer:
simple...
Explanation:
If an acid is not listed here, it is a weak acid. It may be 1% ionized or 99% ionized, but it is still classified as a weak acid. Any acid that dissociates 100% into ions is called a strong acid. If it does not dissociate 100%, it is a weak acid

Answer:
Tt
Explanation:
Hello. I believe that you are only referring to question 2, since question 3 does not present all the answer options. As such, the offspring of a cross between a tall pea plant (TT) and a low pea plant (tt) would be completely "Tt."
To achieve this result, you must make a Punnett Square, which is a frame that allows you to combine the alleles of the parents in a cross to project the alleles of the offspring.
Alleles are those characterized by the letters associated with characteristics. As you saw in the question above, tall pea plants have "TT" alleles that are dominant alleles, while low pea plants have "tt" alleles that are recessive alleles. In this case, to use Punnett Square, you must put the alleles of one parent in the first row and the allele of the other parent in the first column. Then just combine each allele, as shown below:
T T
t Tt Tt
t Tt Tt
As you can see all the offspring will have the "Tt" alleles. This means that the entire offspring will be tall pea plants. This is because the recessive allele "t", which is related to pea plants, can only be expressed in the presence of another recessive allele. However, the dominant "T" allele, which is associated with tall pea plants, can be expressed in any situation.
what is the difference between exocytosis and endocytosis
Answer:ur mom

Explanation:
Mass is the independent variable in Part I, speed is the independent variable in Part II and kinetic energy is the dependent variable for both Parts.
Whta is the independient variable?The independent variable is the variable in an experiment that isn't changed along with the experimental procedure.
Conversely, the dependent variable is the variable we need to measure and it is modified by experimental conditions.The independent variable can be considered the cause, whereas the dependent variable is the effect.In conclusion, mass is the independent variable in Part I, speed is the independent variable in Part II and kinetic energy is the dependent variable for both Parts.

) Name the 3 polymers of carbohydrates and describe the structure and function of each of them.
Answer:
The correct answer is - starch, glycogen, and cellulose.
Explanation:
Polysaccharides are the name of the polymers of carbohydrates that have long chains of monosaccharides connected together. Carbohydrates like starch, glycogen, cellulose, are long polymers of monosaccharides.
Starch produced by plants and is a long-term storage form of sugar. Starch is also the major source of food and is made of two major polysaccharides amylose, linear polysaccharide of α-1,4-linked d-glucopyranose with a few branches of α-1,6 linkages, amylopectin, amylopectin possesses a branched structure with α1–4 as well as α1–6 glycosidic linkages.
Glycogen is a polymer of glucose residue with α-1,4 glycosidic bonds and after every 10 residues, there is branches off via α-1,6 glycosidic linkages. It is the second storage form of energy.
Cellulose is the structural polymer that is made up of unbranched chains of glucose molecules linked via beta 1-4 glycosidic bonds every second glucose is inverted in this polysaccharide.
