Answer:
The heart beats 100,000 times a day, is the size of your fist, and creates enough energy to drive a truck 20 miles. Yes, the heart is our hardest working and most important muscle. One of the most surefire ways to rapidly increase your heart rate is Spinning. This low impact exercise can be performed at home if you have your own bike, or in a group setting. The faster you pedal and the more resistance you face, the higher your heart rate elevates. Having gained popularity because of its low impact and low injury risk, it (not surprisingly) also improves body composition, decreases fat mass and lowers blood pressure and cholesterol. Shorter bursts of high intensity exercise have been proven to increase your heart rate more than steady, low intensity workouts. Interval training of high intensity exercise followed by a short rest period will result in both a healthier heart. For a less regimented, non-traditional workout, hiking will go a long way to ensure your heart rate is increasing steadily over a longer period of time. Hiking is a good way to improve your cardiovascular fitness, particularly if your route includes some hills, which will force your heart to work harder. Meditation activates our bodies' “rest-and-digest” functions, which counteracts our “flight-or-fight” responses. Integrating the practice into a daily routine has been linked to lower heart rate and blood pressure
Explanation:
The activities like running, swimming, cycling, jumping ropes, playing tennis, etc increase your heart rate, while the activities like deep breathing, relaxing in a silent environment with extreme calm, formal walking, relaxing exercises, etc, decreases your heart rate.
What is Heart rate?Heart rate may be defined as the number of times your heart beats or pumps in a minute with respect to your bodily activities.
Some physical activities are known to increase heart rate immediately while some of them may assist in the reduction of the heart rate significantly. Both these processes are good enough to maintain the overall condition of health prominently.
To maintain your proper cardiovascular health, it is mandatory to do more physical exercises or activities that improve your heart rate gradually.
The names of those activities are briefly mentioned above.
Therefore, it is well described.

A Histoplasmosis (caused by the fungal pathogen Histoplasma capsulatum) is typically seen only in the Ohio and Mississippi river valleys, whereas Aspergillosis (caused by the fungal pathogen Aspergillus fumigatus) is widespread regardless of geographical location. Which of the following statements describes why this disparity with regards to disease distribution occurs?
1. Histoplasma capsulatum is an endemic fungus that prefers sols erwiched with bal guano, whereas Aspergillus furgatus is a ubiquitous soll langus.
2. Individuals are not as routinely vaccinated against Aspergillosis as compared to Histoplasmosis
3. Histoplasma capsulatum is an opportunistic fungal pathogen affecting immunocompromised individuals, whereas Aspergillus fumigatus is a true fungal pathogen affecting both healthy and immunocompromised individuals.
4. The arthropod vector that carries Histoplasma capsulatum is only found in the Ohio and Mississippi valley regions, whereas the arthropod vector that carries Aspergillus fumigatus is found in many geographical locations.
Answer:
3. Histoplasma capsulatum is an opportunistic fungal pathogen that affects immunocompromised individuals, while Aspergillus fumigatus is a true fungal pathogen that affects both healthy and immunocompromised individuals.
Explanation:
Histoplasmosis is an oprtounista mycosis, that is to say that it increases in number in our organism occasionally generating infectious and non-protective pathology like the commensal flora.
Histoplasmosis respects American geographic limits and is because it lives in tropical and freshwater climates.
Histoplasmosis pathology is triggered if the person has a deficit in the immune response and if the risk of living or transiting the endemic area is corrected.
On the other hand, the aspergillus fungus is a fungus that enters the inhalation routes in a sporulated form and developed in the lungs, generating a high fatal risk, since it triggers inflammatory and necrotic symptoms in the lung, regardless of whether the person is immunodeficient or not. ... There were people who were shaved by this fungus and even selected hypersensitivity pictures, that is, the opposite of an immunodeficiency.
The Fungi of the Aspirgillus group do not discriminate against age, immune status, or other factors ... only inhalation of the spore is required to develop the pathological picture.

Which form of natural selection does the graph represent? A graph has trait value on the horizontal axis and proportion of individuals on the vertical axis. The original population increases to a maximum point at the center, and then decreases. The population after selection increases, decreases, increases, and then decreases again. The maximum of the original population is the minimum of the population after selection. directional selection disruptive selection sexual selection stabilizing selection
Answer:
directional selection
Explanation:
Directional selection is the most common type of natural selection and occurs when some individuals with characteristics favorable to the conditions of the environment in which they live, have survival advantages over individuals who do not have this advantage, who end up dying.
Imagine, for example, a graph showing the directional selection in the same species of moths. Moths of the same species have white and brown collations, in summer, brown moths can camouflage themselves on tree trunks, while white moths cannot and are easily captured by their predators, which means that the amount of white moths decrease. In this graph, the population of white moths would be at a minimum, at the same time that the population of brown moths would be at maximum.
However, with the arrival of the reverse, snow begins to cover the trees, allowing white moths to camouflage themselves more easily. The brown moths, then, are very exposed to predators, causing their population to reach the minimum while the population of white moths reaches the maximum.

An adult with a history of tanning has his genome sequenced. The beginning of a protein-coding region of his DNA reads ATGGGGATATGGCAT. If the protein-coding region of a healthy adult reads ATGGGGATATGAGCAT, identify the site and type of mutation.
Answer:
Explanation:
The protein-coding region of a healthy adult reads ATGGGGATATGAGCAT.
The beginning of a protein-coding region of the tanning individual DNA reads ATGGGGATATGGCAT
The site of mutation is close to the end - GGCA - between the two G's, a base (A) has been deleted.
Thus this type of mutation is termed deletion: a process whereby one or more bases are removed from a nucleotide sequence of DNA.

In captivity, tigers and lions have been known to interbreed and produce hybrids, known as ligers. Why does this NOT make them the same species, according to the biological species concept
Answer:
Explanation:
A cross between a tiger and a lion will produce an hybrids. During fertilization it has been observed that both the father and the mother contributes equally to the genetic makeup of the offspring this therefore will make the liger have 50%gene from the tiger and 50% gene from the lion which is different genetic makeup from the parents.
Since the parents are of two different species the offspring will always be of a different species because its makeup is genetically different from the two parents it is a combination of two species forming a new species.
If the parental species are the same i.e two lion or tiger the offspring will be of the same species but a combination of the parental gene.

: What is lymph? What is lymph? thick carbohydrate matrix that supports cells in various tissues of the body the portion of blood that contains red blood cells the layer of lipids that collects under the skin for protection and insulation protein-rich blood plasma that has left capillaries the portion of blood that contains white blood cells and platelets
ANSWER;
protein-rich blood plasma that has left capillaries
Lymph is un reabsorbed interstitial fluid which are trapped in the capillaries called lymph capillaries. it is pale in color(compare to red of the the blood),and continuously flood the body tissues for fluid balance and waste removal.
Macrophages and lymphocytes (WBC) are the principal cellular components,however it also contain proteins,lipids.It is similar to blood plasma,except for higher amounts of lipids but will lesser amount of WBC and platelets.
Its special channels are the lymphatic vessels of the lymphatic system,which are the lymph nodes and vessels.
The functions of Lymph are:
Responsible for the removal of tissues bathing the tissues(Interstitial fluids ) from the tissues.
Transport of fats from the lacteal during absorption.
Transport of WBC across from the L.nodes to the bone.
it also mediates in immune response,through the transport of antigen-presenting cells.
it is similar to blood because it is a circulating fluids,through special vessels,and both linked by network of capillaries.
However, more wbc,rbc,platelets,oxygen are present in blood than the lymph. In addition because it returns proteins,it is said to contain proteins,but in actual sense if lacks protein
Cystic fibrosis is a genetic disease that results from a malfunctioning chloride transport protein. This causes the accumulation of a thick mucous in the lungs and around the pancreas. Why might an individual with cystic fibrosis have malabsorption and nutrient deficiencies
Answer:
In cystic fibrosis, there is an alteration in the chlorine channels of all cells, so all kinds of body secretions are affected.
Body fluids thicken at the intestinal level, forming a mucus that blocks the ducts that carry digestive enzymes from the pancreas to the intestine.
These enzymes are responsible for generating nutrients or proteins, vitamins and even fats are absorbed.
Explanation:
This intestinal factor results in malnutrition, growth impairment, hypovitaminosis, decay, anemia, capillary fragility, decline and fatigue.

You are working to catalogue some of the species in the Amazon rainforest
before they become extinct from logging. You collect 3 organisms that all look
similar to the Coral snake and do a phylogenetic analysis on them before
classifying and naming them. The Coral snakes DNA barcode is
ATTCGCGATAC. Compare it to each sample organism's DNA barcode to
determine how related they are to the Coral Snake, from closest to furthest.
Organism 1: ATTGGCCATAC
Organism 2: ATCCGGGATAG
Organism 3: ATTCGCCATAC
Answer:
The organism closest to the coral snake is organism 3, followed by organism 1 and finally organism 2.
Explanation:
The more similar the DNA composition of the organisms, the closer and more closely related they are. With that we can say that the coral snake is closer to organism 3, since the sequence of nitrogenous bases in its DNA is more similar, in relation to other organisms. After organism 3, it is organism 1 that most resembles a coral snake. Organism 2, however, has a different DNA composition, the organism being less similar and the more distant from the coral snake.
