A person who has a weakened immune system may not be able to fight against infection because

Answers

Answer 1
Answer:

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 2
Answer:

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.

EOC Biology. A strand of DNA contains the sequence GGC-CAT. What is the complementary strand of mRNA for this sequence? Please help

Answers

GGC-CAT - strand of DNA
 xxx- xxx  - strand of mRNA
---------------------------------------------------------------------------
The first, let's see what connect with what:
when we talk about DNA and complementary strand of DNA:
guanine connects to cytosine (and vice versa)
thymine connects to adenine (and vice wersa)

when we talk about DNA and complementary strand of RNA:
guanine connects to cytosine (and vice wersa)
adenine (in DNA) connects to uracil (in RNA)
thymine (in DNA) connects to adenine (in RNA)
-----------------------------------------------------------------------------------------------
GGC- CAT - strand of DNA
CCG- GUA - complementary strand of mRNA

 complementary strand of DNA would be: CCG- GTA
(in complementary strand of RNA: thymine is replaced with uracil)

Greetings, 
n00nst00p :)
CCG-GUA :) (because its an mRNA strand it can't have the amino acid Thymine or (T) so we replace it with a U.

Each tip (sp 1-4) represents a different species of ant. Species 1 is the outgroup. Of species 3 and 4 possessed a Thymine a nucleotide position 45, while species 1, and 2 possessed an Adenine, then what kind of character is the A nucleotide at position 45?A. Convergent.B. Homoplasious.C. Derived.D. Ancestral.

Answers

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.

  • in this case, the presence of nucleotide at position 45 in species 1, and 2 are shows ancestor character as it is not present in Of species 3 and 4 possessed a Thymine a nucleotide position 45 are derived.
  • Convergent evolution occurs when the trait is evolved independently in two groups, which is not present here.
  • Homoplasoius traits are those which are not found in the common ancestor also incorrect as it is not the case here.

Thus, the type of character is the A nucleotide at position 45 is - C. Derived.

Answer:

C. Derived

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.

Which of the following is not a reason for the lack of a fossil record from the Precambrian time? A. The single-celled organisms that existed during that time did not leave easily identifiable fossils. B. Like the rocks of the Phanerozoic eon, Precambrian rocks contain many visible signs of complex life forms. C. Multi-celled organisms evolved in the oceans during the latest years of the Precambrian time. D. Precambrian rock has been eroded or metamorphosed over billions of years, and very little of it remains at the surface.

Answers

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.

Looking through a microscope, you see a cell forming a cell plate during cytokinesis. Which cell are you looking at?

Answers

If a cell plate is seen being formed, then that would mean that a cell wall would be in the process of forming thus you would be looking at a PLANT CELL.

in order to use the Hardy-Weinberg equation to calculate genetic variations in a population which of the following conditions must exist in the population

Answers

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.

Further explanation

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:

  • Such organisms are diploid
  • only reproduce sexually
  • generation that does not overlap
  • random marriage
  • infinite population size
  • same frequency alleles in both sexes
  • no migration, mutation or selection
