Leah, LaRenda, and Gabi decide to test what factors influence water
absorption by an egg. They remove the shell from 3 eggs by dissolving
them in vinegar. They create three different water solutions. One is pure,
100% distilled water, a second is 50% water/50% corn syrup, and the third
is 100% corn syrup. The mass of each egg is measured before they are put
into a single solution for 24 hours. The mass of the eggs is then measured,
and the data recorded below: Based on the data this group gathered, the
most appropriate hypothesis would be
Answer:
how long well that take
In this experiment, the independent variable they are testing is the type of solution in which the egg is placed.
What is the independent variable?In the data, the independent variables are the factors that do not depend upon the other factors, on the other hand, dependent variables depend on independent variables.
In the experiment they used three different solutions ate three different water solutions. One is pure, 100% distilled water, a second is 50% water and 50% corn syrup, and the third is 100% corn syrup, all are three independent solutions.
The independent variable is the cause which does not depend on any other factor in your study, all the solutions are different mixtures creating different variables.

Answer: In an ecosystem, a population is a group of animals that live in the same area and are the same species. For example, a herd of zebras would be a population, but a horse would not be considered apart of the population because it is a different species than the zebra. (a species are animals that can mate and produce offspring that can also mate).

Find an everyday product in your home that has at least some synthetic materials. Write a paragraph tracing its lifecycle.
(I don’t care what the product is, the paragraph can have a minimum of 5 sentences.)
Answer:
The everyday product in my home having synthetic material is non-stick pans. it is used in everyday for cooking purpose. The modern non-stick pans have a coating of Teflon (PTFE or polytetrafluoroethylene) and teflon is a synthetic fluoropolymer. it is constitute of many strong carbon-fluorine bonds which allow it resistant to solvents.
The average lifecycle of non-stick pan is five years and your its last days will be seen when the surface starts to peel. It is advice to change the non-stick cookware after few years as it can affect the food and health of a person.

Which list correctly orders the forms of radiant energy by increasing
wavelength?
A. infrared light, radio waves, ultraviolet light, visible light
B. visible light, ultraviolet light, radio waves, infrared light
C. radio waves, visible light, ultraviolet light, infrared light
D. radio waves, infrared light, visible light, ultraviolet light
Answer: Option D.
radio waves, infrared light, visible light, ultraviolet light.
Explanation:
Radiant energy is energy electromagnetic radiation that travels by waves or particles. It is measure in Joule. There are different type of electromagnetic radiation and they are defined by the amount of energy, photons and wave lengths.
Radio waves have photons with low energies and wavelengths, microwaves have little, infrared waves have more than the two, ultraviolet have more, x rays have more energy photons and wavelengths, then gamma rays have more.

Which of the following is NOT true about adaptation? A. Adaptation helps organisms survive in their environment. B. Adaptation can be a physical change in the organism.
C. Adaptation will always be the same regardless of the environment.
D. Adaptation can lead to evolution over many generations.
Answer:
c
Explanation:
Adaptation is a heritable behavioral, morphological, or physiological trait that has emerged through natural selection to preserve or improve an organism's fitness. Therefore, option (C) is correct.
What is adaptation?The term "adaptation" refers to a behavioral, morphological, or physiological trait that is inherited and has developed as a result of natural selection to maintain or improve an organism's fitness in response to a specific set of environmental conditions. Adaptation can be thought of as a heritable trait.
One useful illustration is the capacity to conceal oneself. Camouflage is an adaptation that helps an organism blend in with its surroundings so that it is not obvious to other organisms in those same circumstances. The organism is also able to protect itself from the hostile environment thanks to its adaptations.

How can changes in trophic levels affect an ecosystem’s health and stability?
Answer:
Trophic levels are part of an energy cascade that allows for energy consumption, conservation, and retention.
Explanation:
By altering trophic levels in an ecosystem, there is shift between the readily energy available within one specfic trophic system. If you remove wolves, for instance, normal prey could increase en-masse. In this way, the removal of wolves allows for an energy expansion that increases and accelerates the growth of that prey species. In their growth, they attain their energy from elsewhere, say specific plants off which they eat.

Carbon in the ocean originates from the atmosphere.
lease select the best answer from the choices provided
true or false
Answer:
true
Explanation:
Carbon in the ocean originates from the atmosphere; that is true as the carbon in the ocean's main source is the atmosphere, where carbon dioxide (CO2) dissolves into the surface waters of the ocean through a process called gas exchange.
What is the role of carbon ?Carbon is an essential element for life on Earth, and it cycles through various reservoirs such as the atmosphere, ocean, land, and biosphere, the ocean is a major carbon sink, meaning it stores large amounts of carbon. But carbon dioxide is a greenhouse gas that is naturally present in the atmosphere, and its concentration has increased significantly over the past century due to human activities such as burning fossil fuels that harm all living organisms.
As a result, carbon in the ocean comes from the atmosphere; this is true.

Which would cause the body to release more water through the excretory
system?
A. Losing salt through the skin
B. Eating salty foods
C. Jogging in a gym
D. Sweating on a hot day
Answer:
B
Explanation: Hormone control of water and salt
Rehabilitation of water is regulated by the antidiervative hormone (ADH) in negative feedback. ADH comes out from the pituitary gland in the brain. Except for fluid levels in the blood, the hypothalamus causes pituitary to release ADH in the blood. ADH works to increase the absorption of water in the kidney. It puts more water back in the blood, increases the concentration of urine. When there is too much fluid in the blood, sensor in the heart indicates the hypothalamus due to a decrease in the amount of ADH in the blood. It increases the amount of water absorbed by the kidney, resulting in a large amount of diluted urine.
Aldosterone, a hormone that passes through the kidney, controls the transfer of sodium in the blood from nephron. When sodium level falls in the blood, aldosterone is released in the blood, which leads to sodium from nephron to blood. This induces water to flow into the blood via osmosis. Renin has been left in the blood to control aldosterone.

A. Amylase breaking down starch in the mouth
B. Churning of food in the stomach
C. Segmentation of food in the small intestine
D. Chewing of food in the mouth
Answer:
C segmentation of food in the small intestine
Explanation:
mechanical digestion occurs only in the mouth and that is the only one that does not occur in the mouth.Even though Both mechanical and chemical digestion occur in the mouth. ... The muscles in the stomach walls churn the bolus (mechanical), allowing it to mix with digestive enzymes and gastric acids (chemical). This process converts the bolus into a liquid called chyme. Digestion continues in the stomach for several hours. so c is the answer

Explain why decomposers are an important part of a food chain.
Answer:
Decomposers are vital to the food chain because they help recycle nutrients back into the system.
Explanation:
Decomposers like fungi and bacteria play most important role. They break down material that are dead or unused and turn them into nutrients in the fields or soil that plants use to grow.
Answer:
Decomposers are the organisms which change over complex materials into less difficult ones, often changing organic materials into inorganic ones. This, in turn, makes those assets available for use by other organisms. Decomposers, then, are crucial to the cycling of supplements in the ecosystem.
