Just took the test in Buzz.
Chloe reads that given the correct conditions, cuttings from certain plants will form roots along the stem, enabling a new plant— identical to the parent plant—to grow. Chloe wants to investigate whether rooting hormone is beneficial or detrimental in this process. She takes cuttings from a shrub. For Group 1, she places some shrub cuttings in potting soil in partial shade. For Group 2, she dips some shrub cuttings in rooting hormone, places them in potting soil, covers them with a clear dome, and places them in direct sunlight. She waters the groups equally. She pulls up some cuttings after 3 days and again after 6 and 9 days to observe and measure root growth. Write a hypothesis for Chloe's experiment.
Answer:
The correct answer is - If you use the rooting hormone when cloning plants from cuttings, then it will be beneficial for the cuttings.
Explanation:
A hypothesis is a possible explanation or solution behind the particular natural world process or phenomenon. It is formed on the basis of the observation of the phenomenon or process, how it works or what characteristics it shows.
In this study, it is found that the root hormones promote the growth in the clonings from the cuttings of plants thus, the provided hypothesis is the correct hypothesis for the experiment given.

how can you survive a very cold winter
Answer:
Prepare! Follow our winter survival kit checklist for tips on proper clothing, winter car kits, home supplies, and more.
Hypothermia and frostbite are the real dangers. Even in 50 F temperatures, you’re at risk of losing too much core and limb heat.
Protect your body heat. Protect it, trap it, and treat it like the precious resource it is.
Keep covered. Wind and exposure are the enemy. Exposed skin accelerates heat loss, especially through wind.
Dress in layers. The air trapped between each layer holds your body heat, like your own personal hot tub. Plus, layers give you better control over regulating body heat so you can avoid dangerous sweating.
Avoid sweating and stay dry. Besides moisture loss, sweating is bad because water on your skin makes you colder. That’s why we sweat to begin with — it’s the body’s air conditioning system.
Snow is an insulator. Don’t be afraid to use it for shelter.
Avoid eating snow. You lose a lot of core heat by melting snow inside your body. Melt it outside your body instead.
Alcohol does not warm you. Sorry, Russia!
Hydrate. Severe cold can be just as dangerous as severe heat. Stay hydrated.
Don’t travel unless you have to. Conserve energy. Stay where you’re most likely to be found. Especially if you’re in a nasty storm where navigation and shelter is difficult.

The different levels of protein structure are known as primary, secondary, tertiary, and quaternary structure. The primary structure is the sequence of amino acids that make up a polypeptide chain.
16. What force is needed to accelerate a 500 kg object at a rate of 10 m/s2?*
(3 Points)
Answer:
The second one
Explanation:
The formula to calculate force is:
F=m*a
So, 500 kg*10 m/s= 5000 N
The reason why it is not the last one is because we are looking for force, which is measured in Newton's.

What structure in the female reproductive system produces eggs?
Vagina
Ovary
Fallopian tube
Cervix
Ovary structure in the female reproductive system produces eggs. Thus, the correct option is B.
What is female reproductive system?The uterus, fallopian tubes, ovaries, and the vagina are a woman's internal reproductive organs. The muscular, hollow tube known as the vagina connects the uterus to the vaginal opening. The muscular walls of the vagina allow it to expand and contract.
The primary roles of the female reproductive system are to produce eggs (ova) that can be fertilized and to create the environments and space necessary for a baby to grow. The female reproductive system also possesses the components required for a man's sperm to interact with a woman's ova in order for this to occur.

Why do the neuron and epithelial cell look so different?
They have a different function in the body.
A different section of DNA is activated in the nucleus.
They were created from different parent cells.
A different tissue results from a collection of each type of cell.
More time was spent creating the neuron.
Answer:
Nerve cell shapes vary according to the number, branching and disposition of their projections or dendrites, collectively known as arborization. This determines their capacity for interacting with their environment and with other nerve cells or neurons, hence their computational ability and roles.

The muscular organ that digests food, called the stomach. It is a component of your digestive system (GI). When you eat, your stomach contracts and releases the acids and enzymes needed to break down the meal. Thus, option C is correct.
What is function of Stomach?In the anterior part of the abdominal cavity in most vertebrates, the stomach is a sac-like enlargement of the digestive system situated between the esophagus and the small intestine.
Before food is delivered into the intestine, it is mechanically distributed and stored in the stomach as a temporary container.
Carbohydrates are chemically digested in the stomach. Since the stomach only makes protease and lipase (pepsin breaks down proteins into peptides),
it is unable to chemically digest carbohydrate (gastric lipase that digests lipids into glycerides).
Therefore, Stomach is digestive organ in human
