Answer:

1- Presence of phenotypic variation

2- some phenotypic variation due to genetic variation

3- the given trait has an impact on fitness  

Explanation:

The evolutionary theory by natural selection proposed by Darwin in his publication “On the origin of species” (1859) is based on a series of assumptions that enable to understand the amazing biodiversity on the Earth. First, individuals are not identical among them, i.e., there exists variation in the traits among the members of a given population, species, etc. Second, phenotypic variation leads to differential survival and reproduction of the organisms that are best fitted to the environment (i.e., competence among the members of the population). Finally, phenotypic traits are passed from generation to generation (i.e., phenotypic variation is inheritable), thereby favoring offspring from parents more adapted to the environment.

Who devised a technique for determining the blood group of a dried bloodstain, which he applied to criminal investigations?.
Dominik [7]

Landsteiner Bertillon devised a technique for determining the blood group of a dried bloodstain, which he applied to criminal investigations.

<h3>What about blood group?</h3>
  • According to the presence or absence of antibodies and hereditary antigenic compounds on the 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 genes that a person got from their parents determine what blood type they have.
  • There are numerous systems for classifying blood types, but ABO is the most popular one.
  • The ABO group is divided into four main categories: A, B, O, and AB.
  • There are eight more blood types within these groupings.
  • Each of the eight blood types has a particular ability to save lives.
  • The majority of people (37% of the population) have the blood type O+, which is the most prevalent. This indicates that there is a greater need for this blood type for blood transfusions.

weeeeeb [17]

Answer:

D diffusion across a membrane

Explanation:

Based on whether or not energy input is required, there are two types of processes viz: passive and active. Passive processes are those that do not require energy input in form of ATP while active processes require energy input to occur.

An example of passive process is DIFFUSION, which is the movement of molecules from a region of high concentration to a region of low concentration across a membrane. Diffusion is passive i.e does not require energy, because movement occurs down a concentration gradient.

Other processes in the options like cell division, DNA replication and protein synthesis all require energy input to occur.
