Compare and contrast the methods used by bacteria and protozoa to stay alive. Even when conditions within the environment are
unfavorable for the growth and survival of the organism.
Answers
Answer:
Protozoa formed cysts and bacteria produces endospores.
Explanation:
Protozoa can survive in dry and unfavourable environments, by producing resting cysts that enable them to remain dormant until conditions are favourable while on the other hand, bacteria produce special dehydrated cells called Endospore which helps the bacteria to survive unfavourable environmental conditions. These endospores help bacteria to resist high temperature, radiation, drying, and other environmental extremes.

Phagocytoses microbes after recognizing PAMPs; acts as an Antigen Presenting Cell to activate another type of immune cell F. Does not directly kill microbes; secretes histamine to initiate an inflammatory response.
Answers
Answer:
Cytotoxic T cell - kills infected human cells after recognizing antigens displayed on MHC class 1 B.
Helper T cell - does not directly kill microbes; after recognition of a specific antigen displayed on MHC Class 2, it secretes molecules that help other cells to do so.
B cell - phagocytoses microbes after recognizing specific antigens; secretes antibodies
Natural Killer Cell - kills virus-infected human cells by releasing perforin and granzymes.
Macrophage - Phagocytoses microbes after recognizing PAMPs; acts as an Antigen Presenting Cell to activate another type of immune cell
Mast Cell - Does not directly kill microbes; secretes histamine to initiate an inflammatory response.
Explanation:
T cell are immune-response cells that originate in the bone marrow but migrate and develop in the thymus gland. They are of two classes; Cytotoxic T cells and Helper T cells.
Cytotoxic T cell - kills infected human cells after recognizing antigens displayed on MHC (Major histocompatibility complex) class 1 B.
Helper T cell - does not directly kill microbes; after recognition of a specific antigen displayed on MHC Class 2, it secretes molecules that help other cells to do so.
B cells are formed and develop in the bone marrow. They make antibodies against antigens, and phagocytoses microbes after recognizing specific antigen.
Natural Killer Cells are cytotoxic lymphocytes of the innate immune system. They kill virus-infected human cells by releasing perforin and granzymes.
Macrophages are a type of white blood cells that detects and phagocytoses microbes after recognizing PAMPs (Pathogen-associated molecular pattern) They also act as Antigen Presenting Cell (APCs) to activate another type of immune cell
Mast Cells are cells found in the connctive and they function as part of the immune system of the body. They do not directly kill microbes. They secrete histamine to initiate an inflammatory response.
Elements in the same column of the periodic table of the elements all
A. have the same number of protons.
B. share the same atomic structure.
C. have similar physical characteristics.
D. share the same number of neutrons
Answers
Answer:
C
Explanation:
elements in the same column have different number of protons and different number of neutrons.
Elements in the same column of the periodic table of elements all share the same atomic structure. Thus, the correct option for this question is B.
What is the similarity in the elements that belong to the same column?Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons. They are the electrons involved in chemical bonds with other elements.
The number of protons governs the atomic number of an element. So, elements never have the same number of protons. The number of neutrons along with protons governs the atomic mass of an element which also never remains the same.
The physical characteristics of any element depend on the majority of the attributes. So, it may also vary from element to element.
Therefore, elements in the same column of the periodic table of elements all share the same atomic structure. Thus, the correct option for this question is B.

A person infected with the Ebola virus will experience symptoms within 2 to 21 days of being exposed to the virus. During this time, the virus uses cell machinery to make copies of itself. Ebola symptoms include fever, severe headaches, vomiting, and unexplained bleeding or bruising The reproductive cycle of the Ebola virus that most likely causes symptoms within 2 days is - A lysogenic because the onset of the symptoms is delayed Blytic because the individual experiences symptoms very quickly after infection C lysogenic because the onset of symptoms occurs in individuals over 60 years of age Dlytic because the virus affects the circulatory system
Answers
Recall that in a lytic cycle of reproduction, the host cell undergoes lysis following virus replication. This results in rapid onset of symptoms.
A fish maintains its depth in fresh water by adjusting the air content of porous bone or air sacs to make its average density the same as that of the water. Suppose that with its air sacs collapsed, a fish has a density of 1.18 g/cm3. To what fraction of its expanded body volume must the fish inflate the air sacs to reduce its density to that of water?
Answers
Answer:
0.153
Explanation:
We know the up-thrust on the fish, U = weight of water displaced = weight of fish + weight of air in air sacs.
So ρVg = ρ'V'g + ρ'V"g where ρ = density of water = 1 g/cm³, V = volume of water displaced, g = acceleration due to gravity, ρ'= density of fish = 1.18 g/cm³, V' = initial volume of fish, ρ"= density of air = 0.0012 g/cm³ and V" = volume of expanded air sac.
ρVg = ρ'V'g + ρ"V"g
ρV = ρ'V'g + ρ"V"
Its new body volume = volume of water displaced, V = V' + V"
ρ(V' + V") = ρ'V' + ρ"V"
ρV' + ρV" = ρ'V' + ρ"V"
ρV' - ρ"V' = ρ'V" - ρV"
(ρ - ρ")V' = (ρ' - ρ)V"
V'/V" = (ρ - ρ")/(ρ' - ρ)
= (1 g/cm³ - 0.0012 g/cm³)/(1.18 g/cm³ - 1 g/cm³)
= (0.9988 g/cm³ ÷ 0.18 g/cm³)
V'/V" = 5.55
Since V = V' + V"
V' = V - V"
(V - V")/V" = 5.55
V/V" - V"/V" = 5.55
V/V" - 1 = 5.55
V/V" = 5.55 + 1
V/V" = 6.55
V"/V = 1/6.55
V"/V = 0.153
So, the fish must inflate its air sacs to 0.153 of its expanded body volume

Answers
Answer:
generating tetanus-specific memory B cells
Explanation:
Memory B cells are cells of the immune system that produce antibodies against specific antigens present in pathogenic organisms. The B lymphocyte cells produce clonal memory B cells after the first exposure to the antigen, a process known as clonal selection. Subsequently, memory B cells that circulate in the bloodstream trigger a rapid secondary immune response (after a second exposure to the antigen) by producing antibodies against specific antigens that activated their parent B cell. Moreover, the DPT vaccine includes purified tetanus toxins (i.e., target antigens) that induce clonal expansion in specific B cells, thereby generating a population of memory B cells that produce specific antibodies rapidly in secondary immune responses.
