How and why might the R0 value change over time during an outbreak? pls help
Answer:
Vaccinations
Explanation:
For example, if a disease has an R0 of 18, a person who has the disease will transmit it to an average of 18 other people. That replication will continue if no one has been vaccinated against the disease or is already immune to it in their community. So if you have (for example) a vaccination then you're less likely to get it, resulting in a lower R0

The incorrect choice is D. Light has a constant speed of 300,000,000 m/s in any medium.
Actually, wave speed differs from one medium through another, since wave speed is a property that depends on medium in which a wave is propagating. so we can say that it's speed varies from medium to medium.

4. According to Newton's laws what might happen to the Earth if its orbit moved farther away from the Sun? The Sun's gravitational pull on the Earth would increase b. The Earth's gravitational pull on the Moon would increase b The Sun's gravitational pull on the Earth would stay the same d. The Sun's gravitational pull on the Earth would decrease C.
Answer:
The Sun's gravitational pull on the Earth would decrease.
Explanation:
According to Newton's laws, if its orbit moved farther away from the Sun, the Sun's gravitational pull on the Earth would decrease. The correct option is d.
What is gravitational force?Gravitational force is the force that attracts everything towards it. The third law of Newton, or the law of action-reaction, states that:
As soon as object A applies a force (referred to as an action) to item B, the opposite force is then applied to the first object (referred to as a reaction).
In other words, when two things exert a force on one another, the two forces have the same magnitude (while the directions are opposite).
The gravitational force that the Earth exerts on the Sun is consequently equivalent to and, in fact, opposite of the gravitational force that the Sun exerts on the Earth, according to Newton's third law.
Therefore, the correct option is d. The Sun's gravitational pull on the Earth would decrease.

What are three ways that the function of a root is helped by its structure
Answer:
Subsequently, question is, what are three ways that the function of a root is helped by its structure? A root's four major functions are 1) absorption of water and inorganic nutrients, 2) anchoring of the plant body to the ground, and supporting it, 3) storage of food and nutrients, 4) trans locating water and minerals to the stem.
Explanation:
In addition to absorbing water and nutrients, they also anchor and support the plant and store food.
What are roots?Roots are defined as a vascular plant's subterranean portion. Water and essential minerals are taken up by a plant's roots from the earth and sent to the stem. The plant's roots firmly anchor it to the earth. They first give a plant the anchor it needs to stay put. More significantly, a plant's roots are its life support system because they transport nutrients, water, and air up into the leaves.
The root hairs have a vast surface area, making them ideal for absorbing water from the soil. The absorption increases as surface area increases. There is a semi-permeable barrier on each root hair. Anchoring the plant, absorbing water and dissolving nutrients, transferring them to the shoot, storing nutrients, vegetative reproduction, and binding soil particles are just a few of the crucial roles that roots play in plants.
Thus, in addition to absorbing water and nutrients, they also anchor and support the plant and store food.

Vasoconstriction of the afferent arteriole and/or vasodilation of the efferent arteriole will cause a(n) __________ in glomerular filtration rate (GFR).
Afferent arteriolar vasoconstriction decreases blood flow into the glomerulus, which causes the glomerular-capillary blood pressure to decrease, leading to a(n) decrease in the net filtration pressure and a resultant decrease in the GFR.
What happens if the afferent arteriole is vasoconstriction?Constriction of the afferent arterioles has two inpact
it increases the vascular resistance which lessens renal blood flow (RBF), and it lowers the pressure downstream from the constriction, which lower the GFR.
Thus, Afferent arteriolar vasoconstriction reduces blood flow into the glomerulus, which causes the glomerular-capillary blood pressure to lessens .
