How do scientists say the melting ice can contribute to disease occurrence? Also example
Answer:
In the melting of icebergs, icebergs could potentially contain long-dormant bacteria and viruses. Those viruses trapped in ice and permafrost for centuries, can be reactivated. That means melting those ice could potentially open a Pandora's box of diseases. Including some that have caused global epidemics in the distant past.
Example: babesiosis
As of regular ice. The freezing of bacteria in water isn't just an old practice and ice from unclean sources could also contain disease, when melted and ingested or touched this ice as well could transmit disease not so long-dormant, however still unpleasant.
Example: AIDS

In physics, what is a black body?
Answer:
Blackbody, in physics, a surface that absorbs all radiant energy falling on it. The term arises because incident visible light will be absorbed rather than reflected, and therefore the surface will appear black. The concept of such a perfect absorber of energy is extremely useful in the study of radiation phenomena.

Describe the water cycle in a brief paragraph. Use terms that you know are associated with the water cycle.
Answer:
The water cycle or hydrologic is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. ... As clouds move up and over mountains, the water vapor condenses to form precipitation and freezes.
Herbicides are being used to kill weeds in a nearby field. The plants absorb the herbicides from the soil. Which organelle
in the plant will most likely store the absorbed herbicide waste?
ribosome
vacuole
chloroplast
mitochondrion
Answer:
The answer is B. Vacuole
Explanation:
As the plants have no used for the herbicides, it will be transported to it "waste bin" which is the Vacuole.
Definition of Vacuole: Vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.
Also, completed a test with same question, and got it right.
Vacuole organelle in the plant will most likely store the absorbed herbicide waste.
What is Vacuole?
Animal, plant, bacterial, protist, and fungal cells all include vacuoles. It has the size of a giant sac and is one of the biggest organelles found in cells.
Vacuoles are bordered by a thin membrane and filled with fluid and any molecules they take in.
This is their basic structure. Because both are membrane-bound sacs, they resemble another organelle called vesicles, however vacuoles are substantially bigger than vesicles and are created when numerous vesicles fuse together.
Therefore, Vacuole organelle in the plant will most likely store the absorbed herbicide waste.

a. Splitting water
b. Carbon fixation
c. Movement of hydrogen ions through the membrane
d. The burning of sugar molecules
Answer:
c.
Explanation:
during photosynthesis, what is the source of the carbon i the sugar that is created
Answer:
Plants get the carbon from the air that humans exhale. They breath it in and use it for photosynthesis.
Explanation:
Took biology last year.
During photosynthesis, what is the source of the carbon is the sugar that is created is carbon dioxide in the air.
Photosynthesis is the process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.Carbon dioxide serves as the source of carbon, and it enters the photosynthetic process in a series of reactions called the carbon-fixation reactions (also known as the dark reactions).Stages of photosynthesis:
(i) Absorption of light energy by chlorophyll.
(ii) Conversion of light energy to chemical energy and splitting of water molecules into hydrogen and oxygen.
(iii) Reduction of carbon dioxide to carbohydrates.

false
Answer:
The answer is false!
Explanation:
I took the K12 science quiz. I hope this helps! Have a blessed day! :)
The statement "An aquarium with a glass lid is an example of an isolated system" is false as light, air, and heat can transfer through the glass lid.
What is an aquarium?An aquarium is an artificial place that is made for putting fish and other water animals in houses buildings and other places. Aquariums are made up of glass so can we, so we can see the fish's aquarium also have oxygen pumps the water also changed in the aquarium from time to time and. The aquarium is kind of decorative.
Aquariums are made up of glass, and they are open from the top so that fish can get air.
An aquarium is not an isolated system as light year and heat can transfer through the top and fishes are living organisms that need an open system to breathe and live.
Therefore, the statement is false.

Explanation:
The diagram below shows the exchange of carbon dioxide (CO2) and oxygen (O2) between a cell and the blood flowing through a capillary.
In this diagram, the molecules of CO2 (represented by x’s) are moving from an area of--
Answer:
From an area of higher concentration to an area of lower concentration.
Explanation:
The molecules of CO2 are moving from an area of higher concentration to an area of lower concentration. Carbondioxide is produced as waste product in the cell during the process of respiration. This carbondioxide gas is loaded in blood cells because in the cell, concentration of carbondioxide gas is higher while on the other hand the concentration of carbondioxide is lower in the blood cells. This carbondioxide gas exchange in the lungs with oxygen which is required in the process of respiration for the production of energy in the form of ATP molecules. So from the conclusion we can say that CO2 moves from an area of higher concentration to lower concentration.

Light behaves in specific ways. It can be reflected, refracted, or absorbed, and under certain conditions, run into different kinds of interference. Which explanation best describes why light is refracted as it enters water?
A. The light bends when it enters water due to its reflection.
B. The speed of light remains the same as it moves from air to water, causing the light to reflect.
C. The speed of light increases when it enters a different medium, but it doesn't bend.
D. The speed of light changes as it moves from air to water, causing the light to bend.
Answer:
D
Explanation:
Refraction is generally defined as the change in the direction of a wave as it travels from one medium to another. Light is a form of wave and light refraction is caused by a change in the speed of light as it moves from air to water, causing the light to bend in the process. The medium of travelling has to be transparent.
The change in the speed and direction is due to the variability in the refractive index of media. Light travels faster as it moves from a medium of higher refractive index to a medium of lower refractive index and vice versa.
The correct option is D.
