<u>Answer:</u>
Medications design to experiment test impact on the heart rate are blood thinners, beta-blockers, calcium channel blockers and potassium channel blockers.
<u>Explanation:</u>
In this, we are talking about medicine design which impacts the heart rate. The problem of irregular heart rate is called atrial fibrillation may increase the risk of stroke and heart disease. For reducing the chances of stroke, doctors prescribe blood thinners. If your Heart rhythm is off but the rate isn't too fast then it wouldn't be a problem. But when the heart rate is very faster that is 100 beats per minute for very long then the bottom pumping chamber that is the ventricles can become very weak which leads cardiomyopathy which further leads to heart disease. There are many medications used to the slow erasing heart these are:
1. Beta-blockers.
2. Calcium channel blockers.
3. Potassium channel blockers.
If you aren't bothered with the symptoms then your doctor will straightly start with correcting your heart's rhythm but if you are struggling with symptoms then your doctor may recommend you an anti-arrhythmic medication to steady your heartbeat and help ease those symptoms.
Amiodarone is both a sodium channel blocker and potassium channel blocker. It is one of the most effective anti-arrhythmic drug available.
I think everything is correct besides letter G. personally i would circle the other option- ‘dominant.’ other then that, i think everything is correct
What I did was I said the plates moved 3 centimeters per year and and times it by 100 million years and you get how far the plates have moved against each other. When they move that far against each other, the land would break and pile up to create mountains. Under the sea, the earth would collide and and create a chain of volcanoes. I got a 4/4 for this question, hope this helps you. Good luck!
Answer:
e. All of the above are considered species under at least one species concept.
Explanation:
All of the abovementioned conditions satisfy at least one condition of species definition. Further arguments are given below to support each statement,
a. A species is the <u>monophyletic group</u> of individuals who has a <u>common ancestor</u> which could be <u>distinguished from the closest phylogenetic relative</u> based on <u>conserved genes</u> (16S in bacteria and 18S in eukaryotes). In the statement above, beetles satisfy this condition.
b. A species is the group of individuals that are capable of <u>exchanging genes or can interbreed</u>. In the above statement, birds who are interbreeding with each other must be a single species.
c. A metapopulation is generically defined as the group of populations who are <u>separated by space</u> but are the <u>same species according to phylogenetic analysis</u>. Thus, the metapopulation of salamanders who are linked by gene flow (gene migration) should be treated as one species.
d. The word "<u>lineage</u>" already conveys the message that these bacteria belong share <u>sample place in the phylogenetic tree</u> and they are capable to adapt the same environmental niche. Therefore, they should be considered as one species. This can be easily tested via 16S rRNA sequencing.

Q:</span><span>Proteins have a variety of functions within a living cell. Describe at least three of the possible functions of proteins, and explain how proteins can be</span><span>
A:Any of a group of complex organic macromolecules that contain carbon, hydrogen, oxygen, nitrogen, and usually sulfur and are composed of one or more chains of amino acids. Proteins are fundamental components of all living cells and include many substances, such as enzymes, hormones, and antibodies, that are necessary for the proper functioning of an organism. They are essential in the diet of animals for the growth and repair of tissue and can be obtained from foods such as meat, fish, eggs, milk, and legumes.</span>
