Which of the following indicates that an endothermic reaction has occurred?
O Heat is released
O water is formed
O Salt is produced
O Temperature decreases
The following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.
What is the significance of the endothermic reaction?There are two types of reactions, such as the reaction that requires heat to form the product, the endothermic reaction, while some of the reactions that release heat are called the exothermic reaction, and the exothermic reactions have more energy at the reactant side than the product side. In the case of a endothermic reaction, the product usually has more energy than the reactants, and the change in free energy here is positive.
Hence, the following indicates that an endothermic reaction has occurred when temperature decreases, which is in the last option as the endothermic reaction needs heat to carry out the reactions.

What are chromatin and its functions?Eukaryotic cells' nuclei include a combination of macromolecules called chromatin, which is made up of DNA, RNA, and protein. Heterochromatin (condensed) and euchromatin are the two types of chromatin. The main proteins that make up chromatin are termed histones, which act as bases for the DNA to wrap around to form the "bead-like" structures known as nucleosomes.Functions of chromatin:DNA packagingTranscription regulationChromatin and DNA repair

Explanation:
An organism that breaks down organic matter into simpler materials (like carbon dioxide) is called a decomposer. Decomposers absorb nutrients from living things or the organic matter they leave behind. They do not need to kill to get their food. Do your results suggest bears are decomposers? Explain your reasoning.
Answer:
No, bears are consumers
Explanation:
Both decomposers and consumers are heterotrophic organisms, i.e., they cannot produce their own food. There are four different classes of heterotrophic organisms: decomposers, herbivores, carnivores and omnivores. The decomposers are heterotrophic organisms that return nutrients to the soil from the organisms that break down. Moreover, bears are classified as omnivores (consumers) that need to kill to get their food. These animals obtain nutrients and energy from both plant and animal sources.
Answer:
Bears are consumers

. If a suggested daily protein consumption of .8 grams / Kg. Body weight is recommended, how many protein Kcals would be represented in the diet of a 220 lb. Individual with no suggested health concerns or limitations? (Kgs. = lbs. / 2.2 ; The caloric density of protein is 4 Kcals / gm.)
Answer:
The correct answer would be - 320 kcal.
Explanation:
Given:
Required protein amount is - .8 grams/kg
kg = lbs/2.2
weight = 220
then, weight in kg = 220/2.2 = 100 kg
solution :
requied amount of protein in normal individual:
= 100* 0.8
= 80 grams.
Now kcal by this amount of protein would be :
= 80*4
= 320 Kcal
Thus, the correct answer would be - 320 kcal.
The amount of protein Kcals in the individual's diet would be 320 Kcals.
The recommended daily protein consumption = 0.8grams / Kg body weight
The body weight of the individual is given as 220 lbs.
The weight of the individual would need to be converted to Kg.
Conversion factor between Kg and lbs is given as: 1 Kg = 2.2 lbs
The weight of the individual in Kg = 220 lbs * 1 kg /2.2 lbs ) = 100 kg
Amount of recommended protein intake of the individual based on body weight will be: 0.8 grams/ Kg * 100 Kg = 80 grams
Caloric density of protein per gram = 4 Kcals / gram
Therefore, protein Kcals in the individual's diet will be 4 Kcals / gram * 80 grams = 320 Kcals
The amount of protein Kcals in the individual's diet would be 320 Kcals.

A certain chocolate bar contains 6 mg of caffeine in a 1.5 oz. Serving. The king-size version of the chocolate bar is 85 grams. How much caffeine, in mg, would you consume if you eat the entire king-size bar?Fill in the answer in the blank provided. Mg of caffeine
Answer:
The amount of caffeine that would be consumed if one eats the entire king-size bar will be 11.99 mg
Explanation:
This question can be reframed in the manner below for better understanding.
If 1.5 oz or ounce of a chocolate bar contains 6 mg of caffeine, how many milligrams (mg) of caffeine is contained in 85 grams of the same chocolate bar.
Firstly, the ounce should be converted to grams
If 1 ounce = 28.35g
1.5 ounce = ?
= 1.5 × 28.35/1
=42.53g
Hence, 42.53g of the chocolate bar contains 6 mg of caffeine
85g of the chocolate will contain
42.53g = 6mg
85g = X
where X is the amount of caffeine that will be consumed in mg
X = 85 × 6/42.53
X = 11.99 mg
The amount of caffeine that would be consumed if one eats the entire king-size bar will be 11.99 mg

Chap wanted to see if planting seeds deeper into the soil had an effect on plant height. He took ten containers and planted radish seeds at varying depths. He used the same type of soil, kept the plants in the same location, and gave them each 20 milliliters (mL) of water each day. Then, he measured the height of the sprouts every day for two weeks. What are the independent (test) and dependent (outcome) variables in Chap's experiment?
Answer:
Independent variable: Planting depths of seeds
Dependent variable: plant height
Explanation:
Independent variable in an experiment is the variable that the experimenter changes or manipulates in order to bring about a measurable response. In this experiment involving the planting of radish seeds at varying depths, the DEPTH AT WHICH THE SEEDS ARE PLANTED is the independent variable.
Dependent variable is the variable that is measured in an experiment. It is the variable that responds to the changes made to the independent variable. In this experiment, the HEIGHT of the radish plants measured is the dependent variable.
