A person with an immune system which is weakened may not be able to fight against infection reason being that the white blood cells which makes up the immune system, fighting off infection and protecting the body against disease which cause organisms are weak.
For a person to be able to fight disease the immune system should be highly complex. For health maintenance thee should be balanced and strong immune system.
Impaired immune response can pose to a serious bad health.
To avoid the influence of immune someone should avoid emotional stress, environmental and chemical exposure and physical stressors for example lack of enough sleep.
Answer:
His immune system cannot fight against invading pathogens.
Explanation:
Weaken immune system represents a state of immunodeficiency, in which immune system of an individual fails to fight properly with infections and cancer.
This is due to inability of body to make functional immune cells, such as neutrophils, T cells, B cells, and macrophages or decreased production of these cells and other components of immune system that provide protection against invading pathogens.
In this case, the type of character is the A nucleotide at position 45 is - C. Derived.
The derived characters or traits are that arose in the most recent common ancestor and passed on the lineage. It can be referred to as traits that are not present in older ancestors but in recent lineage.
Thus, the type of character is the A nucleotide at position 45 is - C. Derived.

Answer:
Explanation:
Derived kind of character is the A nucleotide at position 45.
Derived character: Derived kind of character is one that evolved in the lineage and leading up to a clade and that sets members of that clade apart from other individuals
Example of a derived character: the loss of a tail, a trait that first appeared in an ancestor of apes and man.
The right answer is B
The development towards 1.4 Ga of eukaryotes, aerobic organisms such as unicellular algae, will be decisive for the oxygenation of the Earth's atmosphere.
The first multicellular organism is a red alga dating back to 1200 Ma during the Mesoproterozoic era (part of Precambrians). Various forms of life with soft bodies dated between 600 and 541 Ma constitute what is called the Vendian fauna, that is to say the fauna of the Ediacarien.
The appearance of a great diversity of small shelly fauna from 541 Ma will mark what is called the Cambrian explosion.
Answer: All organisms must reproduce.
Explanation: Trust me G
APEX. Just trying to help people out who also have this question.
Population of living creatures or living organisms.
Because what can reproduce is a living creature/organism.
The Hardy-Weinberg Principle states that alleles and genotype frequencies in a population will remain constant from generation to generation without any other evolutionary influence. These influences include perfect pairing, mutation, selection, genetic drift, gene flow, and Meiosis steering.
The seven assumptions underlying the Hardy-Weinberg equation are as follows:
