why do animals need carbohydrates in their diets
Answer:
Carbohydrates are energy-providing feed components composed of carbon, hydrogen, and oxygen. They should make up about 75 percent of an animal's diet. The energy they provide powers muscular movements. Carbohydrates also produce the body heat that helps keep the animal warm.
5. Molds and bacteria contain hydrolytic enzymes used to breakdown proteins,
lipids, etc.
a) (5 Points) Why does food not spoil as fast when it is refrigerated as it
would at room temperature?
b) (5 Points) Meat begins to feel slimy and it smells when it is spoiled due to
a decomposition reaction with oxygen and carbon dioxide. Why would
meats spoil less rapidly when left unsliced?
Answer:Temperature affects storage time and food deteriorates faster at higher temperatures. Microorganisms grow rapidly at room temperature . Thus to slow microbial growth, enzymatic and oxidative processes, food must be stored at room temperature.
Due to decomposition reactions with oxygen or carbon dioxide in the air, meat begins to feel slimy and smell spoiled. ... Because of its smaller surface area, the unsliced meat would have less collisions and therefore, a slower reaction rate.

Is it better for people to learn from others, or is it better for people to learn on their own? {thesis statement} {subject: Writing}
Answer:
on your own?
Explanation:
it sticks better in your head once you fail
im sorry i dont know this i really need points for my maths test
Answer:
It depends on the situation. Most things are better learning from others because others can see what you cant. On the other hand there are some situations were only you can learn from. Take pain as an example. Others can talk about pain as much as they would like but your body dosent know what that feels like unless it feels it on its own and learns from it. An example of learning from others would be smarts such as math, science, history and so forth.

PLEASE HELP! WILL MARK BRAINIEST IF ANSWERED CORRECTLY.
Ocean water is salty. There are many type of salts (ionic compounds), but the salt that causes most of the saltiness in ocean water is sodium chloride (NaCl). (This is the same chemical as the table salt in your salt shaker.)
Use the concept of polarity to describe in detail how sodium chloride (NaCl) dissolves in ocean water.
Answer:
H2O is a polar molecule
the H is slightly positive and the O is slightly negative so the Na is attracted to the O side of the water molecule and the Cl is attracted to the H side of the water molecule

PLS I WILL GIVE YOU BRAINLY What effect I think this new bacteria will have on patient 23's overall health
Answer:
Gut bacteria are an important component of the microbiota ecosystem in the human gut, which is colonized by 1014 microbes, ten times more than the human cells. Gut bacteria play an important role in human health, such as supplying essential nutrients, synthesizing vitamin K, aiding in the digestion of cellulose, and promoting angiogenesis and enteric nerve function. However, they can also be potentially harmful due to the change of their composition when the gut ecosystem undergoes abnormal changes in the light of the use of antibiotics, illness, stress, aging, bad dietary habits, and lifestyle. Dysbiosis of the gut bacteria communities can cause many chronic diseases, such as inflammatory bowel disease, obesity, cancer, and autism. This review summarizes and discusses the roles and potential mechanisms of gut bacteria in human health and diseases.

An unknown substance with a mass of 83 grams absorbs 1,108 J while undergoing a
temperature increase of 11 °C. What is the specific heat of the substance?
Look at picture
ASAP please will mark as brainlist don’t got much time
Answer:
The specific heat of the substance is 1.21 [tex]\frac{J}{g*C}[/tex]
Explanation:
Calorimetry is the measurement and calculation of the amounts of heat exchanged by a body or a system.
There is a direct proportional relationship between heat and temperature. The constant of proportionality depends on the substance that constitutes the body as on its mass, and is the product of the specific heat by the mass of the body. So, the equation that allows calculating heat exchanges is:
Q = c*m*ΔT
where Q is the heat exchanged by a body of mass m, made up of a specific heat substance c and where ΔT is the temperature variation.
In this case:
Q=1108 J c= ? m= 83 g ΔT= 11 CReplacing:
1108 J= c*83 g* 11 C
Solving:
[tex]c=\frac{1108 J}{83 g* 11 C}[/tex]
c= 1.21 [tex]\frac{J}{g*C}[/tex]
The specific heat of the substance is 1.21 [tex]\frac{J}{g*C}[/tex]

What mass of the protein gelatin is needed to make 0.5 L of a 3 g/L gelatin solution? Show your work.
Answer:
m = 1.5 gram
Explanation:
Given that,
Density of protein gelatin, d = 3 g/L
The volume of protein gelatin, V = 0.5 L
We need to find the mass of the protein gelatin. The density of an object is given by :
d = m/V
Where
m is mass
[tex]m=d\times V\\\\m=3\ g/L\times 0.5\ L\\\\m=1.5\ g[/tex]
So, the required mass is 1.5 gram.
