Explain the role that the skeletal system plays in facilitating cardiovascular system function

Biology
1 answer:
Arturiano [62]3 years ago
4 0

Answer:

Skeletal system provide strength and protection to heart and also produces essential blood cells such as RBC and WBC

Explanation:

All organ systems in our body work in co-ordination with each other. Skeletal system comprised of bones and cartilages while cardiovascular system comprises of hearts, blood and blood vessels. Firstly the skeletal system protects the heart and also assists in its pumping along with muscle. Secondly, the blood cells such as RBC and WBC are circulated by the blood throughout the body. However these cells are produced in the bone marrow (inside the bones)

Which of the following sequences shows a frameshift mutation compared to the wild-type mRNA sequence?
Butoxors [25]

Option C:

B. wild-type 5-AUGCAUACAUUGGAGUGA-3 mutant 5'-AUGCAUACAUCUGGAGUGA- 3' 

Explanation:

A frameshift mutation is a genetic mutation such that the triplet nature of gene expression by codons, the insertion or deletion occurs in such as way that it alters the complete sequence of 3 codon sets and can change the reading frame, resulting in a completely different translation from the original.

As it is pertinent to understanding that all genes are normally translated in sets of 3 codons, which typically describes and explain a unique amino acid sequence. Thus, if a frame shift mutation occurs, it can affect many amino acid sequences and finally the entire protein.  

If we look at option B:

wild-type 5-AUG   CAU  ACA  UUG  GAG  UGA-3  

mutant 5’-    AUG   CAU  ACA  UCU  GGA  GUG  A-3’  

An insertion of a base Uracil showed at the end of 3rd codon which affected and altered the whole sequence of codon triplets. This changed all next codons and finally all next amino acids will be altered.

When the term biceps, triceps, or quadriceps forms part of a muscle's name, what does it tell you about the muscle? the muscle h
tekilochka [14]

Answer:

The muscle has two, three, or four origins, respectively.

Explanation

  • A muscle is an organ composed of muscle tissue that contract to facilitate a particular movement
  • biceps,triceps and quadriceps  are types of skeletal muscles since they use bones as levers
  • <em><u>They differ in that; the biceps have two origins, triceps have three origins and quadriceps have four origin.</u></em>
  • <em><u>Bicep is a two headed muscle thus said to have two origins ,triceps have three muscle heads and therefore have three separate origin attachment point while quadriceps are made of four muscles heads hence have four origins. </u></em>

A point mutation changes the DNA sequence CGA to CGT, but the same protein is still produced. Which point mutation occurred?
choli [55]


If the same protein keeps being produced it could be said that nothing is happening even though something happened, and if nothing is changing you could say that it is a silent mutation, which means that the answer is C.) Silent. The change in the amino acids and the nucleotides happened but it is silent and does not affect the outcome of the protein synthesis.
