Which macromolecule is involved in how hemophilia is passed from parents to their children
Serga [27]

Answer:

chromosomes

Explanation:

chromosomes which consist of genes which consist of DNA can pass on traits from parent to child.

it basically works by depending on the gender of the child it can inherit certain traits from its parents

so say the hemophilia is an XX being from the mom and to get the mutation you would need the X that has the mutation and either an X or Y from the dad.

I dont know if hemophilia affects X or Y but that is how the mutation would be passed on.

Explain how super-antigens, such as toxic shock syndrome toxin produced by staphylococcus aureus, often lead to the development
GaryK [48]

Toxic shock syndrome toxin is a super-antigen produced by Staphylococcus aureus bacteria .it causes toxic shock syndrome by stimulating the release of large amount of interleukin-1, interleukin-2 and tumor necrosis factor .

Interleukin-1:

It is a group of 11 cytokines that plays a central role in the regulation of immune and inflammatory responses to infections .

Interleukin-2:

It is a type of cytokine signaling molecule in the immune system .interleukin-2 is apart of the body's natural response to microbial infection and in discriminating self and non self foreign.

tumor necrosis factor :

Tumor necrosis factor is protein superfamily  of type 2 transmembrane protein  containing  tnf homology domain and trimers .these proteins are expressed predominantly by immune cells and they regulate diverse cell functions ,including immune response and inflammation ,but also proliferation, differentiation and embryogenesis.

Staphylococcus aureus:

Staphylococcus aureus is a gram positive pathogen cable of producing a variety of bacterial exotoxin known as super antigens .

Toxic shock syndrome :

Toxic shock syndrome is an acute disease mediated by the production of super-antigenic toxin .it is rare , life threatening complication of certain type of bacterial  infections. often it results from toxins produced by staphylococcus aureus bacteria but the condition may also be caused by toxins produced by group a streptococcus bacteria.

Toxic shock syndrome can affect anyone ,including men , older woman, children and postmenopausal women.risk factors of toxic shock syndrome includes skin wounds ,surgery ,and use of tampons and devices such as menstrual cups contraceptive devices ,etc.

Symptoms of toxic shock syndrome toxin:

A sudden high fever,low blood pressure ,vomiting or diarrhea ,rash resembling sunburn ,muscle aches ,redness of eyes ,mouth and throat ,headache and seizures.

Which of the following is NOT one of the
Dimas [21]

The way that does not successfully classify protists is their size. Thus, the correct option is C.

<h3>What are Protists?</h3>

Protists may be defined as one of the diverse taxonomic groups and particularly a kingdom of eukaryotic organisms that are unicellular and sometimes colonial or less often multicellular and that generally include the protozoans, most algae, and often some fungi.

On the basis of the way that Protists reproduce, they can be subdivided into three types: Sexually reproducing protists, asexually reproducing protists, and conjugation-based.

On the basis of how protists get energy and food, they are again subdivided into three categories.

  • Animal-like protists: Heterotrophs that have the ability to move.
  • Plant-like protists: Autotrophs that have the ability of photosynthesis.
  • Fungi-like protists: Heterotrophs have cells with cell walls.

On the basis of the way that they move, they are subdivided into two types: Motile protists and non-motile protists. They generally move with the help of cilia, flagella, and pseudopodia.

Therefore, the size is not one of the following ways that protists are grouped. Thus, the correct option for this question is C.
