Active transport moves molecules across the plasma membrane of a cell with the help of transport proteins and energy (ATP).
Active transport is the means of transport of molecules across the plasma membrane with the help of energy. This method is usually used for the transport of molecule against their concentration gradient, i.e., from lower concentration to higher concentration.
Plasma membrane is the outer layer surrounding the cell. It is made up of lipid bilayer, proteins, carbohydrates and cholesterol. The lipid bilayer is amphipathic since the lipid head is hydrophilic and its tail is hydrophobic. The plasma membrane is semi-permeable in nature.

Answer:
The disease spread to the neighbourhood.
Explanation:
If the disaster such as earthquake and pandemic etc occurs in the neighbourhood so it also affected the health of the people of that region as well as the people that lives in the neighbourhood. In the case of pandemic, the disease spread to the neighboring area and affect the health of people while on the other hand, in earthquake the people of neighbourhood is also affected if the intensity of earthquake is higher.
The statement that "A clustering appointment type is when patients with similar problems are booked consecutively on the same day" is true. Clustering is type of appointmnet scheduling. In this type of scheduling patients with similar problems are booked consecutively. A block of time is set aside for particular types of cases.
<span>An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.</span>

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.
