Answer: The correct answer for the blank is-
a. support the multiregional model.
Multiregional model is a scientific model that provides explanataion of pattern of evolution of modern humans. It is an alternative explanation of Out of Africa model.
According to this model, modern humans that are present around the world (that in various regions or multiregions of the world) show similarity to the Homo erectus found in Africa.
In other words, species of human beings first originated in Africa as Homo erectus, which then underwent subsequent human evolution upon dispersing in various regions around the world. These species include all archaic forms of human like Homo erectus, Neanderthals, and evolved worldwide as Homo sapiens ( modern human forms).
Thus, option a) is the right answer.
The range of cells receiving the content of copied cells is called the destination area. The correct option is a.
The smallest unit of life is a cell. It is composed of biomolecules. Every living thing is composed of several cell units. Different sorts of creatures contain various types of cells.
The cell divides to form the other cell. This process if called cell division. Cell division occurs during mitosis. All eukaryotic cells go through the process.
There are four stages to the process. The cell divides during the procedure. A daughter cell that is identical to the parent cell is created.
The destination region refers to the set of cells that will get copied cell content. The cell copies the full contest for another cell.
Thus, the correct option is a. destination area.

The question is incomplete. Your most probably complete question is given below:
a. destination area.
b. final cell
c. receiving range
d. receiver cell
darwin's theory is based on observations and conclusions drawn for them.
it is a causo-mechanical explanation of the origin of the species
Answer:
True
Explanation:
Koch's postulates was proposed to show a causative relationship between a microbe and a disease.
Koch's postulates
•The microorganism must be present in large quantity in all organisms affected by the disease, but should not be seen in healthy organisms.
Koch abandoned this due to his discovery of asymptomatic carriers of cholera and of typhoid fever. Asymptomatic or subclinical infection carriers are seen in diseases, especially viral diseases.
•The microorganism must be seperated from a diseased organism and nutured in pure culture.
This can suspended for specific microorganisms or entities which(at the current time) can't be nutured in pure culture. Viruses uses host cells to grow and replicates and not in pure culture.
•The cultured microorganism should lead to disease when it infects a healthy organism.
It says "should", not "must".
NOTE: NOT ALL organisms introduced to an infectious agent will be infected which may be due to certain factors like general health and good immune functioning; vaccination; or genetic immunity. Its best explained using the resistance to malaria as a result of presence of at least one sickle cell allele.
•The microorganism must be reisolated from the inoculated, diseased experimental host and observed as being identical to the basic specific causative agent.
A single pathogen may lead to several disease conditions. A singualr disease infection may be due to several different microorganisms. While some pathogens cannot be cultured in a pure culture in the lab, others can infects humans.
Answer: The correct answer for the fill in the blank is Light dependent phase of photosynthesis.
Photosynthesis ( synthesis of food in presence of sunlight) is primarily divided into Light dependent and light independent phase.
Light dependent phase occurs in the thylakoid membrane within chloroplast and the chemical reactions taking place in this phase are also called Hill reaction. Energy from sunlight is absorbed and converted into chemical energy in the form of ATP and NADPH and Oxygen is produced due to splitting of water in this phase.
