Consider the spread of the following emerging infectious diseases, using the chain of infection: E. coli O157:H7, Lyme disease, Ebola virus, hantavirus, influenza, tuberculosis, vCJD. For each disease, explain how the chain of infection can be interrupted?
Answer:
If one link is stop working.
Explanation:
There are six points at which the chain of infection can be broken or interrupted and a germ can be stopped from infecting another people. The six links are the infectious agent, reservoir, portal of exit, mode of transmission, portal of entry, and susceptible host. If one of the link is broken or interrupted, no infection occurs in the body of an individual because all the links are attached to each other in the form of chain which can stop working if one of it stop working.
Explain how sunlight is the primary source of energy for your own life
Answer: ok...
Explanation:
The continual input of energy, mostly from sunlight, sustains the process of life. Sunlight allows plants, algae and cyanobacteria to use photosynthesis to convert carbon dioxide and water into organic compounds like carbohydrates. This process is the fundamental source of organic material in the biosphere.
Consider the factors that affect muscular strength. Read each scenario and identify whether each would result in a stronger or weaker muscle contraction.
1- Potassium accumulate in the sarcoplasm
2- Increase in muscle belly circumference
3- Lesser proportion of motor neurons to muscle fibres
4- Begin contractions with muscle already 50% contraction
5- Lower sarcoplasm pH
6- Increased stimulus frequency.
7- Circular arrangement of muscle fascicles
8- increased requirement.
Muscles are required in breathing, talking, running, walking, and any body movement. Actin and myosins are protein filaments present in muscle cells that help to contract and relax or change the shape of muscles. Muscles are responsible for the movement or motion of organisms. Joints are the connection between two or more bones. Most joints are mobile.
Muscle strength is determined by several factors. Some of those are the physical shape, size, and innervation of the muscles.
Weak contraction
Potassium accumulates in the sarcoplasm. Contracted lower sarcoplasm pH.Begin contraction with muscle already 50%. The circular arrangement of muscle fascicles.Stronger contraction

What is the food web?When many food chains of an ecosystem are interconnected with each other to make a complex web-like structure is known as the Foodweb.
Lindeman gave the 10% law which means at each step of the food chain when food energy is transferred from one trophic level to the next trophic level, only about 10% of energy is passed on to the next trophic level.
Producers (100%) → Primary consumer (10%) → Secondary consumer(1%) → Tertiary consumer (0.1%).
Therefore, If producers receive 1,000kcal of energy from the sun, the energy received by the tertiary consumers in that energy pyramid is 1kcal.

If you walk through a busy crowd and feel a few different people bump and push past you as they walk by, which skin receptors would be activated?
Answer:
Mechanoreceptors would be activated
Explanation:
The skin is a complex organ that is found covering the entire surface of the human body. The mechanoreceptors are responsible for the sense of touch, that is, the capture of pressure on the skin. They are the Meissner corpuscles and the Vater-Pacini corpuscles, which are made up of nerve endings and connective tissue, in other words, they are receptors that are stimulated by muscle contraction and pressure on the joint elements. It allows to know the position of the body and the degree of contraction of the muscles.

How does a mutation in a sex cell differ from a mutation in a non-sex cell?
A. Mutations in sex cells are more deadly
0
B. Mutations in sex cells can be passed on to children.
c
C. Mutations in sex cells are chromosomal mutations.
a
D. Mutations in sex cells are silent mutations,
Answer:
B
Explanation:
B
A mutation in a sex cell (sperm or egg cell) differs from a mutation in a non-sex cell (somatic cell) in several ways: . Mutations in sex cells can be passed on to children and Mutations in sex cells are chromosomal mutations and may more.
How are mutations can be passed on to children ?Mutations in sex cells can be passed on to children: When a mutation occurs in a sex cell, it can be passed on to the offspring and become a hereditary condition. On the other hand, mutations in non-sex cells cannot be passed on to offspring.
C. Mutations in sex cells are chromosomal mutations: Sex cells contain chromosomes, and mutations in these cells can result in chromosomal abnormalities that can affect the development and health of the offspring.
Thus, A and D are incorrect. Mutations in sex cells are not necessarily more deadly than mutations in non-sex cells, and they are not always silent mutations. The effects of a mutation depend on its location and the function of the gene affected.

Which of the following best describes why we see different moon phases?
A. The moon revolves around the Earth once a month.
B. The earth revolves around the moon once a month.
C. The amount of sunlight hitting the moon changes over time.
D. The earth revolves around the run once a year. (This one ??)
Answer:
It's C.
Explanation:
What we see as phases of the moon is the reflection of sunlight bouncing off the moon's surface.
We see different moon phases because the moon revolves around the Earth once a month.
FACTS ABOUT THE MOON:
The moon is the only satellite that the Earth has. The rotation of the moon around the Earth makes us experience day and night. The moon as a celestial body does not possess a light of its own, hence, the light we see when looking at the moon is that from the sun. It takes a month (about 27 days) for the month to complete its evolution around the Earth. Hence, we see different phases of the moon based on the part of the moon being lit by the sun. This different phases of the moon we observe is only possible because the moon revolves around the Earth once a month.Learn more: https://brainly.com/question/21199365

High altitude adaptation is a complex physiological process that involves an increase in both the number of Hb molecules per erythrocyte and the total number of erythrocytes. It normally requires several weeks to complete. However, even after one day at high altitude, there is a significant degree of adaptation. This effect results from a rapid increase in the erythrocyte BPG concentration.
a. Try to do this without looking at the graphs. If oxygen-binding curves for both high altitude adapted hemoglobin and normal, unadapted Hb were plotted together, would the curve for high altitude adapted Hb be to the left of, to the right of or the same as the curve for unadapted Hb? Explain.
b. Is the oxygen binding affinity of high-altitude adapted Hb higher, lower, or the same as that of unadapted Hb? Explain.
Answer:
a. To the right
b. higher
Explanation:
From the information given:
a.
The oxygen-adsorption curve of the elevated high altitude modified the hemoglobin and this will move to the right because there is a reduced amount of oxygen available at high altitude, as well as an increase in carbon dioxide and H+ ion concentration, temperature, and all of which raise pH and shifts the curve towards the right.
b.
As there is a low relative partial pressure of oxygen at high altitude, the oxygen-binding attraction of high altitude adaptable hemoglobin is greater and higher than that of unadapted hemoglobin under pulmonary oxygen loading. This is important to optimize the oxygen concentration levels in blood circulation and blood tissues.

Of the 23 pairs of chromosomes in any normal human cell, the first ____ pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's _____________ can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.
Answer:
Of the 23 pairs of chromosomes in any normal human cell, the first 22 pairs provide directions for an individual's body and brain development. Scientists now estimate that about half of a person's personality traits and cognitive abilities can be traced to genetic influence and that psychological disorders arise from the interactions of many genes.
Explanation:
Chromosomes are small molecules that have the ability to carry all the genetic information needed to form a living being. These chromosomes are donated by an individual's parents and are used to form 23 pairs that determine all the internal and external characteristics of an organism. Among these 23 pairs, one pair will be responsible for determining the individual's gender, and the other 22 pairs will be responsible for the instructions that will make up the entire body and brain of the individual. Many scientists believe that chromosomes are responsible for even a part of a person's personality traits and that the genes they carry are directly related to the existence of psychological disorders.
The correct fillers for the given statements are: "22" and "personality and cognitive abilities"
Chromosomes are thread-like minute structures found in the nucleus of the plant and animal cells. These are the structures that help in transferring genetic information from one generation to another. Half chromosomes come from the mother and half come from the father's reproductive cells.
Humans have 23 chromosome pairs in their cells, one out of 23 pairs is responsible for the gender of the human embryo or child.the other initial 22 pairs are responsible for providing directions for an individual's body and brain development.On the basis of studies, many scientists say that almost half of the traits of personality and cognitive activities or mental processes to learn or acquire activities are due to chromosomes.Thus, the correct answers are : "22" and "personality and cognitive abilities"

A survivorship curve is a graph that shows the proportion of individuals in a population surviving at different age intervals. The correct statement is that survivorship curve describes the pattern of mortality in a population over time. The correct option is C.
What is Survivorship curve?Survivorship curve describes the pattern of mortality in a population over time. The survivorship curve is divided into three types, i.e., Type 1, Type 2, and Type 3. Survivorship curve type 1 represents a high survival rate throughout the lifespan of the population. It shows that most individuals survive until old age, and the mortality rate increases at the end of the lifespan.
Survivorship curve type 2 shows a relatively constant rate of mortality throughout the lifespan of the population. It indicates that the probability of survival remains the same throughout life.
Survivorship curve type 3 represents high mortality rates among young individuals in a population. It shows that most individuals die young, and only a few individuals survive to adulthood.

All of the following are correct about the typical American diet except that it is ?
A. High in sodium
B. Low in fiber
C. High in Calcium
Answer:
Explanation:
I believe the answer is the last one. The average intake in 2010 was 1030 mg approximately and that, according to experts is not enough.
The American diet is very high in sodium which is not good for your blood pressure. It was, some time ago, recommended that the average intake of Sodium should be about 2 grams. Two hamburgers will shoot that number to the moon, so now it is 4 grams. which if 2 grams was high, 4 grams is super high. Junk food prevails in America.
Fiber is true. It is low. The American Heart Association recommends 25 grams of Fiber a day. The average American takes in 15 which is only 60% of the recommended amount.
