Answer:
amount of copper
Explanation:
The independent variable would be the amount of copper fed into the experimental rats.
An independent variable during an experiment is a variable whose value is not dependent on any other variable being measured in the experiment.
The value of an independent variable is not changed by any other variable in an experiment. In actual fact, the effect of the independent variable is being tested on other variables (dependent variables) in the experiment.
Hence, in an experimental study of the effect of copper deficiency on coat color in rats, the amount of copper fed into the system of the rats will be varied and the effects of this variation on the coat color of the rats would be observed by measuring relevant variables. Therefore, the amount of copper is the independent variable.

Explanation:
Hospital patients often receive medications, nutrients, and water intravenously (IV), which means they are injected directly into the patient’s veins through a needle. IV fluid is not pure water, but is instead a saline solution (water containing NaCl). What do you think is the appropriate NaCl concentration for IV fluid? Why?
Answer:
The answer to the following question is given below.
Explanation:
Saline includes 9 g NaCl dissolved in 1 liter of distilled water utilized primarily for sick people with moisturization.
This NaCl concentration has been presumed to be the physiologic concentration necessary for the restoration of vitamins and minerals by the body to control a suitable osmotic balance.
NaCl is mainly used to cover up the salt missing. In order to help nerves function properly, our bodies do require sodium.

What is a good property of an indicator?
Answer:
Acid base indicators are weak and acids and bases, which are used to signify the end point of neutralization reaction. The type of indicator used for a neutralization reaction depends on the strength of the acid and the base, that are involved in the reaction. A good acid base indicator must have a good pH range and it must be able to produce specific and identifiable color in specific acid base medium.
or
Two good properties of an indicator are as follows-
1) It should be specific- It means that the changes, which are measured by the indicator should be expressed in precise terms so that appropriate assessment could be made.
2) It should be time bound- This means that the measurable changes should arrive withing a particular time limit.
Example of indicator- Litmus is an acid base indicator that turns acidic solutions red and basic solutions into blue color.

why is nectar important for insects?
Answer:
Nectar is important for insects because.. Nectar is an ecologically important item, the sugar source for honey. It is also useful in agriculture and horticulture because the adult stages of some predatory insects feed on nectar. For example, the social wasp species Apoica flavissima relies on nectar as a primary food source. In turn, these wasps then hunt agricultural pest insects as food for their young.
Someone expressing a recessive hair color has _______.
A-1 dominant and 1 recessive allele for hair color
B-2 dominant alleles for hair color
C-2 recessive alleles for hair color
Answer: The answer would be C
Explanation: This is because in order to express a recessive trait one must have no dominant alleles or otherwise the dominant would win out and be expressed instead. For example, if a person had 1 allele for brown hair and 1 for red the brown would win and the same would happen if they had 2 brown hair alleles. Whereas if a person had two alleles for red hair and none for brown, only then would the red trait be expressed. Hope this helped!

The process by which animals and plants obtain energy are different because animals get energy from eating food and plants get energy from sunlight.
Explanation:
Plant get it because they collect energy from the sun and use carbon dioxide and water in the process called photosynthesis to produce sugars.
AND
Animals get it because Animals can make use of the sugars provided by the plants and they can also eat meat or plants to get energy from them so that means when you eat food animals get energy.

The gluten-free diet was originally intended for people with celiac disease, but it's now become a new fad diet for the general population. Many people state that gluten-free diets are beneficial for people who aren't sensitive to gluten, while others suggest that there's no benefit. Use credible resources to evaluate the argument yourself. Do you think there's sufficient scientific evidence to support the use of a gluten-free diet in people who aren't sensitive to gluten? Provide evidence that supports your argument.
Answer:
hey love! so i actually have celiac so i know a lot about this haha! hope this helps!!
Following a gluten-free diet in the absence of celiac disease may be detrimental to health. Nutritional deficiences: Avoiding foods that contain gluten can lead to deficiencies in essential nutrients, including iron, calcium, fiber, folate, thiamin, riboflavin, and niacin.
Explanation:
In recent years, the gluten-free diet has become more of a fad than a medical necessity. ... The study concluded that more gluten consumption is associated with a lower risk of heart disease, suggesting that those who do not suffer from celiac disease or non-celiac gluten/wheat sensitivity should not avoid gluten. Though many health professionals suggest otherwise, it's safe to follow a gluten-free diet — even for people who don't necessarily need to do so. Cutting out wheat and other gluten-containing grains or products will not cause adverse health effects — as long as these products are replaced with nutritious foods.
Answer:
Explanation:
There’s no benefit to a gluten-free diet for people who aren’t sensitive to gluten. Many websites state benefits of a gluten-free diet. These benefits range from weight loss to improved heart health. None of these sites backed up their claims with scientific research. More credible sites consistently state that there’s no scientific research to back up these claims. Right now, there’s no evidence that supports the benefits of a gluten-free diet in people who aren’t sensitive to gluten.
