If a vaccine protects you for most of your life against a particular pathogen, why do you need a new flu shot every year? A. Influenza evolves very quickly and its antigens mutate so that your memory cells from the last vaccine won’t recognize it. B. Influenza is so strong that you need a booster every year to make sure your body can fight it. C. Influenza is a virus, and vaccines only generate memory cells for bacterial infections. D. You don’t need it every year, it is just offered every year for anyone who does not have it yet.
Answer:
If you got a flu shot this year, next year you'll need it again.
Explanation:
This is because the virus changes, usually rendering the previous year's vaccine partly or totally useless. hope this helps you :)
Answer:
A.
Explanation:
Influenza evolves very quickly and its antigens mutate so that your memory cells from the last vaccine won’t recognize it.
The 2020 influenza vaccine was not as efficient because scientists were scrambling to put out a vaccine for Coronavirus. Consequently, Coronavirus cases skyrocketed during the flu season.
Hope this helped!
also.. i have to put coronavirus and not "c0vid-19" because apparently it's too political. lol.

Answer:
two of the DNA fingerprint are same when they contain the same nitrogenous bases in the same location of the DNA.
Explanation:
The DNA fingerprint is one of the most important tool as a forensic medicine expert to to form such condition and rule it out to come to a diagnosis.
DNA fingerprint uses the base pair which a different for all the other human beings. Due to this from the blood or other cells of the body there can be an evidence of the person and this is usually done on a comparative basis.

Give examples of types of pollution and the effects on water quality (examples: sedimentation, stormwater runoff, naturally and human induced occurrences of arsenic in groundwater)
Answer:
Sewage, oil, pesticides and fertilizers affect water quality.
Explanation:
There are three types of pollution i. e. air pollution, soil pollution and water pollution. Smoke and smog are present in the air is the example of air pollution, waste product, using of pesticide and industrial dumping are the example of soil pollution and chemicals in water due to runoff of fertilizer, sewage and oil are the main agents of water pollution. These three types of pollution adversely affected the water quality. Water quality will be affected when the fertilizer or pesticides runoff from land to water bodies. Sewage and oil also lowers the quality of water.

According to the graph, which statement below is true?
A. This enzyme works equally well at all temperatures.
B. This enzyme works best at 10 degrees Celsius.
C. This enzyme works best at 45 degrees Celsius.
D. This enzyme works best at 60 degrees Celsius.
The rate of enzyme activity is at its highest when the temperature is 45°C. Thus option C is correct.
What are the factors affecting enzyme activity ?The optimum temperature for most of the enzymes is between 25-35°C and above 50°C leads to destruction of enzymes
The rate also increases with increased enzyme concentration up to the saturation point
Enzymes work at their optimum pH. The rate of enzymatic reaction depend on substrate concentration.
The accumulation of the products decreases the activity of enzymes, as they combine with the active site of enzymes by forming a loose complex and inhibits the activity of enzymes.
Some chemical substances like co-factors, potassium ion (K⁺), manganese ion (Mn²⁺) can increases the enzyme activity.
water increases the reaction rate. Light increases the reaction rate in some enzymes but harmful radiation like UV rays and X-rays decreases activity.

what are some non examples of hydroshere
The hydrosphere is made up of all the water on the planet, including the water found below the surface and in the atmosphere. A planet's hydrosphere may be liquid, vaporous, or composed of ice. The three surface water bodies on Earth are oceans, lakes, and rivers.
What are some non examples of hydrosphere?It comprises all surface waters that are liquid or frozen, groundwater that is contained in soil or rock, and atmospheric water vapor. The hydrologic cycle continuously circulates almost all of these waters. In wells and aquifers, it can also be found underground as groundwater.
Within the hydrosphere, water circulates in a cycle. Clouds contain water that eventually falls to Earth as rain or snow.
Therefore, Rivers, lakes, and seas are where this water gathers. The cycle is then restarted by its evaporation into the atmosphere. The water cycle refers to this.

A garden has a length of 1.5 x102 m and a width of 0.5 x 102 m. what is the area of the garden?
Answer:
7.5 × 10^3 m^2
Explanation:
The garden described in this question takes the shape of a rectangle, which has a length of 1.5 x102 m and width/breadth of 0.5 x 102 m.
To calculate the area, we use the formula for calculating the area of a rectangle, which is;
Area = length (L) × width (w)
Area = 1.5 x102 m × 0.5 x 102 m
Area = 150 × 50
Area = 7500
This, the area of the garden is 7500m^2 or 7.5 × 10^3 m^2

In humans, the ability to roll up the sides of the tongue into a U-shape is controlled by one gene. Ability to roll the tongue is dominant to the inability to roll it. If two people who can roll their tongues each had one parent who could not, what is the probability that they will have a child who cannot roll his/her tongue
Answer:
25%
Explanation:
male
can roll tongue - cannot roll tongue
female
can roll tongue - cannot roll tongue
If they have a child, the possible combinations are:
1)
father's gene: can roll tongue
mother's gene: can roll tongue
RESULT = THE CHILD WILL BE ABLE TO ROLL HIS/HER TONGUE
2)
father's gene: can roll tongue
mother's gene: cannot roll tongue
RESULT = THE CHILD WILL BE ABLE TO ROLL HIS/HER TONGUE
3)
father's gene: cannot roll tongue
mother's gene: can roll tongue
RESULT = THE CHILD WILL BE ABLE TO ROLL HIS/HER TONGUE
4)
father's gene: cannot roll tongue
mother's gene: cannot roll tongue

Tree-dwelling primates have prehensile tails for gripping branches. Tree-dwelling opossums also have prehensile tails. Many birds and some kinds of bats that feed on plant nectar all have long flexible tongues. Primates use opposable thumbs to help climb. New World monkeys also have prehensile tails, but Old World monkeys do not. Marsupial mammals throughout Australia show a wide diversity of forms that reflect the habitats in which they live. Hawaiian honeycreepers, with their elongated, nectar-sipping bills, all evolved from a finch-like ancestor.Answer and Explanation:
Tree-dwelling primates have prehensile tails for gripping branches. Considering recent ancestors, the prehensile tail trait can be considered as a convergence example that occurred among different groups. But we can also think about it as a common descent if we consider the farthest primates ancestor. Although still controversial, Plesidiapsi might be considered a common ancestor of primates, that evolved from a ree-dwelling mammal with a long tail. It is believed that this animal used to live in trees. Tree-dwelling opossums also have prehensile tails. Convergence. Many birds and some kinds of bats that feed on plant nectar all have long flexible tongues. Convergence. These are two groups that are very separated from each other, and they developed different traits according to their needs separately. Some of the species of these two groups adapted to feed on the same plant so they needed to develop the same characteristic to obtain nectar.Primates use opposable thumbs to help climb.

Farming, grazing of livestock, mining, and drilling combined account for: Over 1/2 of deforestation About 1/3 of deforestation 3/4 of deforestation All of deforestation
Answer:
Over 1/2 of deforestation
Explanation:
Farming, grazing of livestock, mining, and drilling combined account for Over 1/2 of deforestation or more than half of deforestation.
These are few of the major causes of deforestation which is continuously destroying forests and wildlife that leads to global warming.
Forests are destroyed for farming purposes, overgrazing by cattles, urbanization of forests in industries and towns, mining, and drilling should be controlled to save deterioration of the earth.
Hence, the correct answer is "Over 1/2 of deforestation ".

Afferent neurones connect?
A the brain and spinal cord to muscles
B sense organs to muscles.
C one sense organ to another sense organ
D sense organs to brain and spinal cord
Can someone explain to me the answer because I'm confused.
Answer:
These neurons are located in the central nervous system (the brain and spinal cord). Afferent and efferent neurons have to work together in order to sense and respond to stimulus, but they don't directly connect. Association neurons bridge the gap to relay information between sensory and motor neurons.
