Answer:
Light bounces off surfaces property most likely believed by Janssen about light during the time of his invention
Explanation:
Zacharias Janssen is ascribed as a man to discover the compound microscope. Its purpose is to amplify diminutive things so characters can analyze them. There is a mirror attached under the microscope and when light bounces off the mirror it reaches through and nearby the specimen being viewed.
Some elements do not receive light. When a light wave is reflected off a facade, it proceeds back off at an angle similar that the wave beats the surface. Using these more innovative concepts about light enacted scientists to compose new inventions.

According to the CDC, is the flu vaccine safe and effective?
Need answer ASAP pls I’ll give brainiest
Answer:
any vaccine effectiveness can vary, recent studies show that flu vaccination reduces the risk of flu illness by between 40% and 60% among the overall population during seasons when most circulating flu viruses are well matched to the flu vaccine.
Explanation:
this is right i had to to a test and a whole lesson over this. ^^^^ that all is from my notes!
Yes, the flu vaccine is safe and effective according to the CDC.
The Centers for Disease Control and Prevention (CDC) recommends annual flu vaccination for everyone aged six months and older, with very few exceptions. The flu vaccine has been extensively studied, and the CDC and other health organizations have found it to be safe and effective in preventing flu infections and reducing the severity of illness for those who do get infected.
The flu vaccine is developed each year to protect against the most prevalent strains of the influenza virus that are expected to circulate during the upcoming flu season. It stimulates the body's immune system to produce antibodies against the virus without causing the flu itself. While the vaccine's effectiveness can vary from season to season due to changes in the circulating flu strains, it still provides significant protection and lowers the risk of severe complications and hospitalization.
As with any medical intervention, there can be some side effects, but they are usually mild and short-lived, such as soreness at the injection site or mild fever. Serious reactions to the flu vaccine are rare. The benefits of getting vaccinated far outweigh the risks, especially for high-risk groups, such as young children, older adults, pregnant women, and individuals with certain medical conditions.
Overall, the CDC and other health authorities strongly recommend flu vaccination as a safe and effective public health measure to protect individuals and communities from the flu and its potential complications. It is an essential part of flu prevention strategies and is encouraged for everyone to help reduce the spread of the virus and its impact on public health.

How do lichens prepare bare rock to support the growth of plants?
A. They use nitrogen from the air to make nutrients that plants can use.
B. They release acids that help break down the rock to form soil.
C. They replace smaller trees and shrubs that can't get enough sunlight.
D. They add nutrients to the rock and have roots that hold the rock together.
Answer:
B
Explanation:
Did it on AP5X
Lichens prepare bare rock to support the growth of plants by releasing acids that help break down the rock to form soil. Thus, the correct option for this question is B.
What are Lichens?Lichens may be defined as a complex life form that is a symbiotic partnership of two separate organisms, a fungus, and an alga. In this symbiosis relationship between two organisms, the dominant partner is the fungus, which gives the lichen the majority of its characteristics, from its thallus shape to its fruiting bodies.
Lichens are important as early-stage primary succession organisms. They are keystone species in many ecosystems. They serve as a food source and habitat for many animals such as deer, birds, and rodents. They provide nesting materials for birds. They protect trees and rocks from extreme elements such as rain, wind, and snow.
Lichens contribute to soil formation by decomposition as well. There are two primary types of decomposition that contribute to the formation of soil: in-situ decomposition and litterfall.
Therefore, the correct option for this question is B.

A. The mass of the egg white increases as the volume of the enzyme increases
B.The egg white is unaffected by the differing amounts of enzyme
C. Digestion decreases in each stomach as more of the egg whites surface area becomes exposed
D. Digestion increases as the volume of the enzyme increases
Answer:
D
Explanation:
The correct answer would be that digestion increases as the volume of the enzyme increases.
Protein digestion is catalyzed by the pepsin enzyme and aided by HCl. The combined actions of both substances form the basis for the digestion of protein in the stomach. Hence, one would expect the digestion of the boiled egg white to increase with the increase in the volume of the enzyme - all other factors remaining constant.
The correct option is, therefore, D.
What ratio of guinea pigs in the offspring would you predict from a Ss x ss cross?
Answer:
75:25
75% S
25% s
Explanation:
The ratio of guinea pigs in the offspring that we would predict from a Ss x ss cross is 1:1.
What is a genetic cross?
The deliberate breeding of two different individuals that results in offspring that carry part of the genetic material of each parent.
In a cross between a heterozygous dominant (Ss) guinea pig and a homozygous recessive (ss) guinea pig, the expected genotypes would be :
Ss (heterozygous dominant) :1ss (homozygous recessive) : 1S, for every guinea pig that is homozygous dominant (Ss) there will be 2 guinea pigs that are homozygous recessive (ss), resulting in the ratio of 1:1. Therefore, both the ratios will be equal. Therefore, the resulting progeny will have both the genotypic and the phenotypic ratios sames.

color, odor, and size
shape, temperature, and color
Answer:
Size, shape, temperature
Explanation:
Water creates pressure inside the cell that helps it maintain shape. ... Without water, cell membranes would lack structure, and without proper membrane structure, cells would be unable to keep important molecules inside the cell and harmful molecules outside the cell.
Which structure is responsible for the passage of materials into and out of the cell?
Answer:
A
Explanation:
It is the cell membrane
The plasma membrane is a boundary of cell responsible for the movement of any substance in and out of the cell, hence a is the correct option.
What is a cell membrane?All cells have a cell membrane, also known as a plasma membrane, which divides the inside of the cell from the external environment. The cell membrane controls the flow of substances into and out of the cell.
Watery fluid surrounds and fills cells, this liquid facilitates the movement of substances across the cell membrane as well as within and outside the cell.
Some solutes (solids) can pass through cell membranes depending on their nature.
Therefore cell membrane allows the substance to pass into cell and out of the cell, hence option a is correct.
