Answer:

The correct answer is - leads.

Explanation:

In ECG or electrocardiogram, a test that is used to measure the electric activity of the heart of an individual, each electric impulse cause a electric wave to travel through the heart and cause the heart pump to pump blood.

There are electrodes that received the electric impulse in this machines, electrodes have self adhesive pads and attached with various leads mostly 12, that carries the impulses in the combinations that are recorded on the ECG.

Thus, the correct answer is - leads.

Protein molecules are composed of long chains of?
Nataly_w [17]


They are composed of long chains of amino acids.

The building blocks of protein are amino acids. Amino acids are organic molecules made up an alpha (center) carbon atom which is linked to an amino group, a carboxyl group, a hydrogen atom and  a variable component  known as a side chain.

Amino acids are joined to each other by peptide bonds  to form either a short chain called an oligopeptide or  a long chain called a polypeptide.  These chains are what forms the protein.

kirill115 [55]

Ans.

HD (Huntington's disease) is a genetic neurological disorder that occurs due to damage and death of brain  cells. it is caused by an autosomal dominant mutation in HTT (huntingtin) gene, having a trinucleotide repeat section that makes HTT protein.

The mutation leads to an increase in this nucleotide repeat count, associated with formation of altered or mutated huntingtin protein. These altered proteins show deleterious affect on brain cells and result in Huntington's disease.

Thus, the correct answer is 'option A). a mutated gene.'

Which of the following statements is true concerning biodiversity?
Mamont248 [21]

Last one - Biodiversity is the diversity of species in an area, which makes an ecosystem better prepared for major changes

If one crop struggles to grow then there will be plenty of others to substitute it. If a prey animal is dying at a faster rate and harder to find, predators can have other prey options and so forth. Biodiversity makes it so ecosystems can get past change.

A frameshift mutation that occurs very early in a protein sequence would have what effect on the protein's structure? see sectio
ExtremeBDS [4]
I think a frameshift mutation that occurs very early in a protein sequence would have an effect on the structure of the protein such that the primary, secondary, and tertiary structures would be altered. A frameshift mutation occurs when a protein is drastically altered because of an insertion or a deletion. Insertions and deletions cause a change in the length of a gene, which causes a shift in the codon reading frame.
