Answer:
The correct option is a.
Step by step explanation:
The given number is
In the given number two digits are on the left side of the decimal and 6 digits on the right side of the decimal.
We have to round the given number to four significant digits. The left side of the decimal will remains the same but the right side of the decimal will rounded to two decimal places.
Find third digit after decimal. If third digit is greater than 5, then add 1 in second digit. If third digit is less than or equal to 5, then second digit will remains same.
Since third digit is 7, therefore the second digit will become
Therefore option a is correct.
Answer:
d. silencer
Explanation:
Based on the information provided within the question it can be said that the deleted sequence most likely functions as a silencer. This term refers to a DNA sequence that is located thousands of base pairs away from the gene that they actually control. In this situation, seeing as the DNA sequence that was found outside the protein coding region actually affected the rate of transcription when it was deleted then it is considered a silencer.
Final Answer:
If an infectious disease can be transmitted directly from one person to another, it is a B) Communicable disease.
Explanation:
Communicable diseases are those that can be transmitted from one person to another, either directly or indirectly. These diseases are caused by infectious agents such as bacteria, viruses, or parasites. When an individual with a communicable disease comes into contact with a susceptible host, there is a potential for transmission.
The term "communicable" refers to the ability of the disease to be communicated or spread from one person to another through various means, including direct contact, respiratory droplets, bodily fluids, or other modes of transmission. Susceptible hosts are individuals who are at risk of contracting the disease when exposed to the infectious agent.
Options C and D, "Port of entry to a host" and "Port of exit from the reservoir," are related to the mechanisms of disease transmission but do not define the type of disease. The correct answer, in this case, is B) Communicable disease, as it directly addresses the nature of the disease that can be transmitted from person to person.

Answer:
B) Communicable disease
Explanation:
A communicable disease is an illness cause by a pathogen (like bacteria, virus, or parasite) that can be spread from person to person through forms of transmission, such as direct contact, sneezing/coughing, or contaminated objects. Examples of communicable diseases include the common cold and COVID-19.
b: Arteries always carry oxygenated blood.
c: Veins always carry deoxygenated blood.
d: Arteries carry blood away from the heart.
e: Veins carry blood toward the heart.
Answer:
a: There is a unidirectional blood flow.
d: Arteries carry blood away from the heart.
e: Veins carry blood toward the heart.
Explanation:
The human circulatory system includes three main types of blood vessels: arteries, veins, and capillaries. Arteries are the blood vessels that carry the oxygenated blood from the heart to various body tissues. Veins are the blood vessels that pick the deoxygenated blood from body tissues and deliver to the heart. Vena cava is the largest vein that reaches the right atrium of the heart and delivers the deoxygenated blood.
The blood from the right atrium is carried to the right ventricle and finally lungs via the pulmonary artery for oxygenated. The oxygenated blood from the lungs is carried to the left atrium of the heart by a pulmonary vein. The oxygenated blood from the left atrium is carried to the left ventricle and finally to the body tissues by branches of the aorta. This unidirectional blood circulation of the human body ensures efficient delivery of oxygenated blood to body tissues.
In general, blood follows a unidirectional flow in the body with arteries carrying blood away from the heart and veins bringing it back. Though it's typical for arteries to carry oxygenated blood and veins to transport deoxygenated blood, there are noteworthy exceptions, like in the case of pulmonary arteries and veins.
Characterizing blood flow in the human body involves understanding the function and direction of blood movement in arteries and veins. a: There is a unidirectional blood flow is correct; blood does flow in a single direction, moving out from the heart, delivering oxygen and nutrients to tissues, then returning the blood to the heart. d: Arteries carry blood away from the heart and e: Veins carry blood toward the heart are both accurate characterizations of blood flow as well.
However, b: Arteries always carry oxygenated blood and c: Veins always carry deoxygenated blood are not completely true. While it's generally correct that arteries carry oxygenated blood and veins carry deoxygenated blood, there are exceptions. For example, the pulmonary arteries carry deoxygenated blood from the heart to the lungs to pick up oxygen and expel carbon dioxide, while the pulmonary veins carry oxygenated blood back to the heart.
