you don need to actually chew the bread. you can just break it up into smaller pieces. which variable will you change in your investigation?
Answer: The type of bread (independent variable)
Explanation:
You can just change the type of bread you are eating and just hold it in your mouth to test your hypothesis of not having to chew the bread. It’s the easier thing to change when making the experiment. Now your bread is your independent variable because you are not changing anything else but the type of bread. Not sure if your question is talking about the technical terms for the variable or what actual variable in the experiment, so I put down both.
scientists often test their hypotheses with controlled experiments. which of these is a rule for conducting a controlled experiment?
a. change at least two variables at a time
b. keep all variables constant
c. change as many variables as possible
d. change only one variable at a time
Changing only one variable at a time is a rule for conducting a controlled
experiment.
Controlled experiment involves the use of dependent and independent
variables . Changes in the independent variable brings about a
corresponding change in the dependent variable which is then recorded.
It is however important to note that changing more than only one variable at
a time won't accurately determine if the changes in the results were as a
result of one cause. This is why only one variable has to be changed at a
time.

Which of the following distinguishes how the farm bill in its current form differs from the Agricultural Adjustment Act of 1933?
The farm bill provides payments to farmers through indirect means only.
The farm bill allows set funding to purchase farm surplus for government use.
The farm bill pays farmers to grow crops, rather than to not grow them.
The farm bill includes charitable aid to those living in poverty.
Answer:
The Farm bill includes charitable aid for those living in Poverty.
Explanation:
The farm bill is a package of legislation passed roughly once every five years that has a tremendous impact on farming livelihoods, how food is grown, and what kinds of foods are grown. Covering programs ranging from crop insurance for farmers to healthy food access for low-income families, from beginning farmer training to support for sustainable farming practices, the farm bill sets the stage for our food and farm systems. As a leading advocate for family farmers and sustainable agriculture, it’s our job to make sure that this important bill is good for farmers, consumers, and for the natural environment.

Explain how one change in the Earth's biosphere can
cause changes in other Earth systems.
Answer:
interaction in the Earth's biosphere cause the change in other Earth system as the biosphere and atmosphere are dynamic, constantly reflecting these interaction. and Biosphere-Atmosphere Interactions focuses on the sources and sinks of greenhouse gases (GHGs), air pollutants, particulate matter, water, and energy between the Earth's surface and the atmosphere.
The Earth's biosphere is closely interconnected with other Earth systems, such as the hydrosphere (water), atmosphere (air), and geosphere (land). Changes in one part of the Earth's biosphere can have significant impacts on other Earth systems, and vice versa
What is a biosphere?Biosphere means interactions with each other and their physical environment.
For example, changes in land use, such as deforestation or urbanization, can affect the Earth's water cycle and climate. Deforestation, for example, can lead to increased runoff and erosion, which can alter the availability and quality of water in an ecosystem. Deforestation can also lead to an increase in atmospheric carbon dioxide, as trees and other vegetation absorb and store carbon dioxide during photosynthesis. This can contribute to global warming and climate change.
Similarly, changes in the Earth's climate, such as an increase in temperature or a change in rainfall patterns, can affect the biosphere. Warmer temperatures can lead to the range expansion of certain species and the loss of habitat for others. Changes in rainfall patterns can affect the availability of water for plants and animals, which can lead to changes in the distribution and abundance of species in an ecosystem.

describe the mechanism of blood sugar regulation (20 marks)
Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.
The pancreas releases glucagon when glucose levels fall too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High BG levels stimulate the release of insulin. Insulin allows glucose to be taken up and used by insulin-dependent tissues, such as muscle cells.p

Using the __________ system, kingdoms are grouped based on cell structure and type, while the __________ system groups major taxonomic groups into three major domains.
Given what we know, we can confirm that using the using the Whitaker system, kingdoms are grouped based on cell structure and type, while the whoese-fox system groups major taxonomic groups into three major domains.
What is the Whitaker system?The Whitaker system is a classification system to order and organize the diverse biological life found on Earth. This is the most commonly-known system which orders organisms into the 5 kingdoms. What is the Whoese-fox system?This is a much less popular system of classification for biological life. It is considered to be much less specific, containing only 3 groupings.Therefore, we can confirm that based on the statement, the spaces missing correspond to the scientists for who the systems are named after, which are Whitaker and Whoese-fox.
