Answer:
110 kg
Explanation:
Density = Mass / Volume ===> Mass = Density x Volume
Now follow the given:
- Density = 2 kg/L or 2000 g/L
- Volume = 55 L
Apply the rule:
Mass = 55 L x 2 kg/L = 110 kg or 110000 g. ( Liters is cancelled by Liters).
solve 3x-8=-2 then once you find the value of x, substituted it into x-6
x=2, so 2-6=4.

Which one of the organic molecules listed below has more energy stored in its bonds. Proteins Carbohydrates Lipids Nucleic Acids
Answer:
Lipids
Explanation:
Out of the four biological molecules in living systems (carbohydrate, lipids, proteins, nucleic acids), Carbohydrates and lipids have the ability to store energy in their chemical bonds. However, lipids/fats are primarily used by cells for long term storage of energy due to their ability to store more energy than any other organic biomolecule.
The high energy storing ability of lipids is attributed to the carbon bonds in their long fatty acid chain. They store energy in the covalent bonds that form between this carbon elements. The breaking down of one gram of a lipid yields 9 calories of energy, which is more than the 4 calories yielded by proteins and carbohydrates respectively

endosymbiotic theory is prevalent here.
DNA, RNA, and Ribosomes are also all present in all life.
DNA- genetic material! obviously all present
RNA- a single strand of genetic information to go into the ribosome to make proteins
ribosome; the thing that makes proteins!
The mitochondria is an organized organelle, unlike everything else on this list, which is not present in prokaryotes but eukaryotes.
A student does an experiment for a science fair to study whether temperature affects the timing of a cricket’s chirps. The student keeps a cricket in an enclosed box that is heated to different temperatures each day for twelve days. The student records the cricket’s chirps by using a sound-activated microphone so that the timing of the chirps can be measured. The student records the results of the experiment in the table below.
Answer:The timing of the cricket's depends on the temperature of the box
so the answer should be
timing of the cricket's chirps
Explanation:Hi!
There are a few types of variables in these types of experiments. They are independent, dependent, and controlled.
The independent is the one changed by the scientist, or in this case, the temperature. The controlled is the things that remain constant through every case, and the dependent is what is being observed, seeing if it changes through the altercation of the independent variable.
In this case, what is being observed is the timing of a cricket's chirps, because it is being watched whether or not temperature affects it.
Therefore, your answer is the third choice, or the timing of the cricket's chirps.
Hope this helped!

According to the instruction manual analogy, how many new volumes would each new cell contain whenever a cell splits? Write your answer in the space below.
Answer:
Same volume as the cell it is divided from.
Explanation:
The particular volume will be diverse for different sorts of cells. The best answer would be that the new cell will essentially have a similar volume as the one that it formed or divided from. This is valid for most eukaryotic cells except if different variables like mutations or epigenetics condition.
Increasing volume of the cell and now likewise associated with cell division would be during the two phases G1 and G2 in the cell cycle. This is the development period of the cell preparing for division. No matter what are the condition other than mention above if mitosis or division occurs, the cells will ordinarily end with a similar volume as when it began.

The following is an example of what type of figurative language?
The dog was a rocket.
simile
O metaphor
irony
idiom
Metaphor because you are comparing the dog and the rocket without using words "as" or "like", hence option A is correct.
What type of figurative language is a metaphor?A metaphor is similar to a simile when comparing two different things, unlike the simile metaphor does not use the words like or as.
A type of figurative language is a word or expression which means something different from its literal definition. A metaphor substitutes a word or phrase with one that makes an explanation with an image. On the other hand, the simile is also a type of figurative language that compare two different things but uses "as" or "like".
Therefore, comparing the dog and the rocket without using the words "as" or "like", hence option A is correct.

Biological influences on body weight include genetics (such as the FTO-associated gene), metabolic factors (such as low levels of thyroid hormone), and physiologic factors (such as abnormal levels of various appetite-regulating hormones). From the list below, choose all the correct statements about biological influences on body weight.
a. Obesity is associated with lower amounts of UCP1.
b. The thrifty gene theory suggests that people with this gene universally expend more energy compared to those without the gene.
c. The set-point theory suggests that the body responds to both energy restriction and overeating with physiological changes to maintain its weight within a narrow range.
d. Genetic factors account for 20 to 50% of a person’s BMI.
e. People who have the fat mass and obesity (FTO)-associated gene are generally heavier than those without the gene.
Answer:
a. Obesity is associated with lower amounts of UCP1.
c. The set-point theory suggests that the body responds to both energy restriction and overeating with physiological changes to maintain its weight within a narrow range.
Explanation:
Correct statements:
a. Obesity has been associated with a low expression of the UCP-1 gene in the brown adipose tissue. For example, in transgenic mice, it has been shown that the overexpression of the UCP1 gene is associated with the stimulation of fatty acid oxidation.
c. The set point theory indicates that the human body has a preconfigured weight which is based on information contained in the genome. In consequence, the set point theory states that fluctuations in weight are limited, where there are people that have higher weight set points compared to other persons, and inherent natural mechanisms in the body try to maintain within these ranges.
Incorrect statements:
- Genetic factors account for 50-80% of the body mass index (BMI). The remaining value is due to environmental factors and the interaction between a genotype and the environment.
- The Fat mass and obesity-associated gene (FTO) is a gene located on chromosome 16 which encodes for the alpha-ketoglutarate-dependent dioxygenase enzyme. Although it has been suggested that some allelic variants of this gene are associated with obesity, this gene is always expressed (i.e., constitutively expressed) in the hypothalamus, where its expression is linked to the food intake.
- The 'thrifty gene' theory states that gene variants (alleles) evolved to favor a more efficient use of nutrients, thereby promoting diseases associated with an excess of calories such as obesity and type 2 diabetes.
The correct statements about biological influences on body weight include:
Obesity is associated with lower amounts of UCP1.The set-point theory suggests that the body responds to both energy restriction and overeating with physiological changes to maintain its weight within a narrow range.People who have the fat mass and obesity (FTO)-associated gene are generally heavier than those without the gene.It should be noted that there are biological influences that affect the weight of a person.
The individuals who have the fat mass and obesity (FTO)-associated gene are generally heavier than those without the gene. Also, obesity is associated with lower amounts of UCP1.
In conclusion, the correct options are A, C, and E.

a. coronary sinus; left atrium.
b. great cardiac vein; superior vena cava.
c. great cardiac vein; left atrium.
d. inferior vena cava; right atrium.
e. coronary sinus; right atrium.
Answer: Option E.
Coronary sinus, right atrium.
Explanation:
Coronary sinus, right atrium is part of the circulatory system that consist of arteries, arterioles, veins, capillaries that move blood to the heart tissue and remove waste from the blood.
The cardiac veins return deoxygenated blood to the right atrium and it them moves to the right ventricle then to the heart where it becomes oxygenated
The coronary sinus received drain blood from ventricles veins, it then moves the deoxygenated blood to the right atrium which it transfer or move to the right ventricle (through the tricuspid valve which in turn move the blood to the pulmonary artery for pulmonary veins.
