fungal and protist infections, especially those that are deeper than the skin, are especially hard to treat. why?​
matrenka [14]

Answer and explanation:

Fungi and protists are eukaryotic. However, antibiotics selectively targets prokaryotic cells. Thus, the use of antibiotics for the treatment of fungal and protist infection is of no use at the first place. Secondly, if we use the other medicines that could kill the fungi/protists (e.g. fungicides), they could also kill the host's cells (animal's cells). This become further difficult if the infection is deeper in the skin. This is because, we would not be able to apply the medicine as direct application on skin but would give either intravenous or via food. This would increase the chance of imacting negatively the other organs/cells. The only option in such scenario is the surgery, which cannot be 100% effective because some spores may left even after the treatment.

Why is it important that human gametes have half a set of DNA instead of a full set of DNA? Use evidence and scientific reasonin
ladessa [460]
It is important that it has half because there is a half that comes from each parent. so to equal it all out human gametes have a half set of dna instead of a full set

Which part of the chemical equation is incorrect
ikadub [295]

The part of the chemical equation is incorrect is The solution is 10 02, it ought to de 1302.For carbon, on each aspects, there are eight carbon atoms.For hydrogen, on each aspects there are 20 hydrogen atoms.

<h3>What a part of a chemical equation are you able to by no means alternate?</h3>

When you stability an equation you could most effectively alternate the coefficients (the numbers in the front of molecules or atoms). Coefficients are the numbers in the front of the molecule. Subscripts are the smaller numbers observed after atoms. These can not be modified while balancing chemical equations.

The complete question is Which part of the chemical equation is incorrect which is 2C4H10+ 10O2 - 8CO2+10H2O.

  1. To realize if a response is properly balanced among the reactants and the products, you need to calculate the wide variety of atoms of every detail on each aspect of the response and to test if they may be equal.
  2. For oxygen, there are 20 oxygen atoms withinside the reagents and 26 withinside the products, so it's miles essential to grow the wide variety of oxygen withinside the reactants (with out touching the others). For this we positioned thirteen 02 withinside the reactants rather than 10, to have 26 oxygen atoms on every side.

Complete the following vocabulary exercise related to the process of translation of mRNA to protein by the ribosome.Match the wo
vredina [299]

1. The RNA that has an amino acid attached to it, and that binds to the codon on the mRNA, is called a tRNA.

tRNA are molecules involved in protein synthesis (translation) and those molecules connect codons from mRNA with  the amino acids they encode.tRNA has anticodone that binds to mRNA codone.

2. The process, performed by the ribosome, of reading mRNA and synthesizing a protein is called translation.

Translation is a process of gene expression in which proteins are synthesized (translated from the codons on mRNA).

3. Initiation of translation always happens at the start codon of the mRNA.

Translation process can be divided into three stages: initiation (starting off), elongation (adding amino acids to peptide chain that is going to become protein) and termination (finishing up).

4. Amino acids are attached to tRNA by enzymes called aminoacyl-tRNA synthetase.

These enzymes are part of the elongation stage of translation and they catalyze the adding of amino acids.

5. Termination of translation happens when the ribosome hits a stop codon on the mRNA.

Termination is the stage in which the finished polypeptide chain (future protein) is released from the ribosome.
