Bart thinks mice exposed to microwaves will get stronger (maybe he's been reading too much Radioactive Man). You decide to perform this experiment by placing 10 mice in a microwave for 10 seconds. He compared these 10 mice to 10 other mice that had not been exposed. His test consisted of a heavy block of wood that blocked the mouse's food. found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same.
identify
1. control group
2. independent variable
3. dependent variable
4. what are some of the mentioned control variables?
5. what should bart's conclusion be?
Answer:
Control group = mice that had not been exposed
Independent variable = Mice receiving radiation
Dependent variable = Number of mice that are able to push the block of wood.
Control variables = Health of mice, mass of block
Radiation does not have effect on strength of the mice
Explanation:
In an experiment the variable which changes with respect to the other variable is called the dependent variable and the other variable is called the independent variable.
The control group is the group that does not receive treatment which is used to compare the effect of the treatment.
The control variable is another variable that must be held constant when performing the experiment.
Here the
Control group = mice that had not been exposed
Independent variable = Mice receiving radiation
Dependent variable = Number of mice that are able to push the block of wood.
Control variables = Health of mice, mass of block
It was found that 8 out of 10 of the microwave mice were able to push the block. 7 out of 10 of the mice without microwaves were able to do the same. This means that there was no significant difference hence, the conclusion drawn should be that radiation does not have any effect on their strength.

If transpiration didn't take place, would water be able to enter the roots of the plant? Explain your reasoning
Answer:
Yes
Explanation:
If transpiration do not occur water will enter the roots of the plants because water enter through the roots by osmosis and move to the xylem vessels after which it get to the leaves and it is lost by evaporation and transpiration. Transpiration is the process why by water is loss through the stomata opening of the leaves and this help in exchange of gases, reduction of excess water and help in plant growth.

Explain how the structures of plant tissues and organs are directly related to their roles in physiological processes.
Answer:
How the structures of plant tissues and organs are directly related to their roles in physiological processes.
o Plant organs are limited to roots, stems, leaves, flowers, fruit and cones.
o Physiological processes are limited to photosynthesis, cellular respiration,
transpiration, and reproduction.
o Plant tissues are limited to meristematic, ground, dermal and vascular tissues.
o Plant structures are limited to cambium, guard cells, phloem, seed, stomata and
xylem
Explanation: Hope this helps have a safe and happy new year
Roots, stalks, leaves, flowers, fruit, and cones are the only organs found in plants. Photosynthesis, metabolic processes, transpiration, and fertilization are the only physiological activities.
Plant and plant tissues:Photosynthesis and the movement of mineral-containing water ions are critical processes in the development of healthy plants. Plants have three primary structures or organs:
LeavesStemsRootsThey're made up of groupings of specialized tissues with structures that are tailored to the functions they do.
Adaptations are distinctive features that help plants survive in their specific settings. Plants rely on their specialized structures to provide their fundamental requirements, protect themselves from predators, and aid reproduction.

freely movable joint is also known as synovial joint why
Answer:
Why are synovial joints freely movable?
Diarthroses are freely movable articulations. ... The bones of a synovial joint are covered by a layer of hyaline cartilage that lines the epiphyses of joint ends of bone with a smooth, slippery surface that does not bind them together. This articular cartilage functions to absorb shock and reduce friction during movement.
Explanation:
please give me brainly got my answer from G00GLE so of course its correct hope i helped!!!
Answer:
Explanation:
Synovial joints (freely movable joints) allow us the free movement to perform skills and techniques during physical activity. Synovial joints have synovial fluid in the joint cavity that lubricates or 'oils' the joint so it moves smoothly. Synovial fluid is made by the synovial membrane.

A girl is born with hemophilia. Her dad also has hemophilia, but her mother does not.
What genetic explanation can you provide as to why the girl
suffers from hemophilia?
answer:
So daughters get 2 X chromosomes from the mom and dad and if the dad has hemophilia the daughter would get it too and sons would not get because they get Y chromosome from their dad and hemophilia is found in the X chromosome because the X chromosome is the one that has the instructions for making the clotting factor proteins.
Explanation:
A father who has hemophilia has the gene and passes it on to his daughter because daughters get two X chromosomes, one from their mother and the other from their father. This is why daughters of men with hemophilia are called obligate carriers. Since sons only receive a Y chromosome from their father, they would not have inherited hemophilia.

In humans type A blood is caused by the antigen A in the red cells resulting from gene A. Type B is caused by a gene B for antigen B. Type O blood results from the absence of either gene while the presence of both genes causes both antigens to be formed resulting in type AB blood. If a person of blood group AB marries one belonging to blood group O what will be the blood groups of their children? Show the Punnett square for this cross.
Answer:
Type A and type B
Explanation:
This question is describing blood type in humans. According to the question, type A blood is caused by the antigen A of gene A while Type B is caused by a gene B for antigen B. Type O blood results from the absence of either gene while the presence of both genes causes both antigens to be formed resulting in type AB blood.
If a person of blood group AB i.e. genotype (iAiB) marries one belonging to blood group O (genotype ii), the following genotypes of offsprings will be produced (see attached image for punnet square):
iAi - blood type A
IBi - blood type B

A) Use the agriculture biomass to generate a renewable fuel that can be burned to generate electricity
The statement provides the best reasoning for regulating the amount of fish removed from the river by humans is:
A) Regulation will help the ecosystem to remain balanced and contribute to the stabilization of other populations of river organisms.
Explanation:
For the electricity, the use of Biomass meets the demands due to the fact that, it has minimal impact on the environment, does not add carbon dioxide to the atmosphere. Also, it is renewable form of energy.
For the regulation of the amount of fish removed from the river helps to maintain the ecosystem balance. If it was not done, the fishes found in the river will be totally harvested thereby disrupting the chains in that river ecosystem.
