What does a population pyramid represents?
A
a population’s trophic levels
B
a population’s age-sex structure
C
a population’s growth rate
D
a population’s dispersal pattern
Answer:
B: a population’s age-sex structure
Explanation:
A population pyramid is a way to visualize two variables: age and sex.
They are used by demographers, who study populations. A population pyramid is a graph that shows the distribution of ages across a population divided down the center between male and female members of the population. Expansive pyramids mean that the population does not increase much in total number and has many young people.

Before 1896, many scientists concluded that light could not pass through black paper. In 1896, Henri Becquerel observed that uranium salts could cause a plate covered by black paper to react as if light had reached it. How did this observation affect conclusions about light passing through black paper?
A- Scientists ignored Becquerel’s evidence because uranium is dangerous to use, so his study was not valid.
B- Scientists repeated Becquerel’s experiment until it no longer worked and reported that his conclusions were not valid.
C- Scientists had to revise their earlier conclusion because evidence from Becquerel did not support the original conclusion.
D- Scientists stood behind the earlier conclusion that black paper blocks light because it was already an accepted conclusion.
Answer:
D
Explanation:
So, I mean it’s kinda hard to explain given that it just makes sense and I took the test and I was right soooooooo
Yeah
Scientists stood behind the earlier conclusion that black paper blocks light because it was already an accepted conclusion. Therefore, option (D) is correct.
What happens to light on the black paper?A sheet of black construction paper would obstruct light when you tried to shine a flashlight through it. The other side would not be able to see the light, and it would not be reflected. A black item absorbs all light waves and transforms them into heat, which causes the object to warm up.
Uranium, according to Henri Becquerel's theory, would absorb light and reemit it as x-rays. The uranium was placed on photo plates by him. When the plates were developed, he saw that the uranium had in fact been generating radiation resembling x-rays.

1. Predict: How do you expect the spread of a foodborne disease to be similar to and different
from the spread of a person-to-person disease?
PLEASE ANSWER
Answer and Explanation:
The transmission of diseases through food and through people to people, are similar because both are caused by human contact with infectious parasitic agents such as bacteria and viruses. However, it is possible to notice some differences between these two types of transmissions.
Transmission of disease through food occurs when an individual eats contaminated food or drinks contaminated liquid. This contamination occurs due to the lack of hygiene of the handlers and storage problems, which can allow microorganisms, mostly bacteria, to grow in the food. Thus, when the contaminated food is ingested, the microorganisms will release toxins in the stomach that will cause disease. In the case of water, contamination can also happen due to the lack of basic sanitation and the incorrect dumping of garbage and human waste.
Diseases transmitted from person to person can occur in many different ways. One of the best known ways is through the contact of a healthy person with salivary goths or other body fluids of a person with the disease. However, this transmission can also occur through the contact of a healthy individual with the feces of a sick individual and even with physical contact with a sick individual.

Why does the bronchioles get smaller and smaller before they reach the alveoli?
Answer: Parasympathetic stimulation causes bronchoconstriction while sympathetic stimulation causes bronchodilation. During an asthma attack, the muscles that encircle the airway tighten or constrict, limiting the flow of air to and from the lungs.
Explanation: i hope this answers your question and i have a awesome marvelous day.
Answer:
In your lungs, the main airways (bronchi) branch off into smaller and smaller passageways -the smallest, called bronchioles lead to tiny air sacs (alveoli)
the bronchiole end in tiny air sacs called alveoli, where oxygen is transferred from the inhaled air to the blood, after absorbing oxygen, the blood leaves the lungs and is carried to the heart, the blood then is pumped through your body to provide oxygen to the cells of your tissues and organs.

Answer:
Sunlight
Explanation:
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct. Therefore, it is sunlight.

Briefly explain the nature of scientific inquiry. Include discussion of the role that evidence and falsifiability play in the process. Is this a strength or a weakness of the scientific mode of
thinking?
Answer:
Science is a process that involves proof and error. Scientific hypotheses are used to find evidence supporting scientific statements, but new evidence can be used to reject previously accepted ones in order to get closer to the truth.
Explanation:
Scientific inquiries refer to the processes by which scientists study phenomena of the natural world and propose alternative explanations (hypotheses) useful for understanding such mechanisms. When hypotheses are supported by many evidence and studies from different sources, scientific theories associated with these hypotheses become accepted by the scientific community. In science, a scientific statement may become falsifiable when it is contradicted by new lines of evidence and/or new observations.
