Answer:
When a sugary gummy bear is placed in water, there are more dissolved solutes inside the gummy bear.
Explanation:
The sugary gummy bear has more solutes as compared to the water in which it is being soaked. When a sugary gummy bear is placed in water, water enters the gummy bear through osmosis as water tends to move to the place where there are more solutes. The sugar gummy bear has more solutes. So, the gummy bear expands and increases in size due to the entrance of water into it.

Explanation:
1. The father is a non-roller, as was given in the question. Remember that a phenotype is the physical trait displayed by an organism.
2. In order for the father to be a non-roller, the recessive non-roller allele would have to be expressed. In order for this to happen, he would need two recessive alleles.
3. The gene for tongue rolling is dominant, so if the mother is heterozygous (she has one dominant allele and one recessive allele), then she will be a tongue roller.
4. The mother has a dominant allele and a recessive allele.
5. 50% of the offspring have the Rr genotype and 50% have the rr genotype. This means that there is a 50% of having a tongue-rolling child and a 50% chance of having a non-rolling child.
6. Because the possibility of the offspring having either genotype is 50/50, the ratio would be written as 1:1. Both outcomes are equally likely.
7. Because the possibility of the offspring having either phenotype is 50/50, the ratio would be written as 1:1. Both outcomes are equally likely.

Answer: Tapeworms live in almost all land, sea, and freshwater habitats Tapeworms also generally inhabit the intestines of humans and animals. They have a series of hooks on one end that they use to attach to the intestine to get nourishment from the host.
Explanation:
Most adult tapeworms live in the intestines of the final hosts, but a few species live in the body cavity.
Answer:
The thermosphere is the outer layer of the Earth's atmosphere, extending from about 53 miles to more than 370 miles above the surface. The temperature increases rapidly in this layer due to the absorption of huge amounts of incoming high energy solar radiation by atoms of nitrogen and oxygen.
Explanation:
It is false that the digestion of polypeptides begins in the mouth with the enzyme pepsin.
<u>Explanation:</u>
The food is consumed through the mouth. Here the saliva has an enzyme called amylase which helps in the breaking down of foods to simpler substances. The food is sent through the oesophagus to the stomach.
In the stomach pepsin breaks down proteins into polypeptides. In stomach is where the enzyme pepsin is found. Then the bile juice secreted in the liver acts upon the digested food and then in the small intestine. Then the feces are excreted through the anus.
