Answer:
Yes
Explanation:
Before the modern times, energy consumption was vital in order to survive. For example, you need heat (thermal energy) to cook food and also be in a decent state of temperature for your body. If they had be never used energy, the generations wouldn't go on. Energy is our main source of living. Solar energy provides sunlight to plants so they can be grown healthily to provide nutritious fruits and vegetables.
To conclude, yes, people did use energy before the modern times otherwise, they would've not survived.
Before the manufacturing revolution, our energy demands were mediocre. For heat, we relied on the sun. Whenever the sun disappointed us, we scorched wood, hay, and withered dung. Our society's energy use changed forever, even with the low-cost automobile and the expanse of electricity. Energy usage increased rapidly, doubling every decade. The price of energy production was decreasing unwaveringly, and the efficient use of energy was not a concern. Drivers lined up at gasoline stations to purchase gas, and President Jimmy Carter went on television to announce that energy preservation was "the moral equivalent of war." New factory orders had already stopped because of multibillion-dollar price overruns, soaring-high inflation, and a slowdown in electricity demand growth due to the early effects of energy preservation. So I think people used energy before modern times.

Which step in cellular respiration produces the most ATP?(1 point)
Krebs cycle
glycolysis
electron transport chain
lactic acid fermentation
Answer:
it's Kerbs cycle which produces most ATP in cellular respiration
Answer:
The answer is electron transport chain
Explanation:
The stage that produces most of the ATP during cellular respiration is the electron transport system (ETS) present in mitochondria.
The formation of ATP occurs by oxidative phosphorylation. Theoretically, 34 ATPs are produced in the ETS by the complete oxidation of a glucose molecule. Electrons are transferred from NADH or FADH2 to O2 by a series of carriers and are coupled to ATP synthase for the formation of ATP.
what hypothesis is being tested in this experiment?
Answer:
According to the web "
Hypothesis testing experiments
In hypothesis testing, an analyst tests a statistical sample, with the goal of providing evidence on the plausibility of the null hypothesis. Statistical analysts test a hypothesis by measuring and examining a random sample of the population being analyzed. ... However, one of the two hypotheses will always be true."

Explanation:
The bloodstream carries the glucose-a type of sugar produced from the digestion of carbohydrates and other foods-to provide energy to cells throughout the body. Unused glucose is stored mainly in the liver as glycogen.
Insulin, glucagon, and other hormone levels rise and fall to keep blood sugar in a normal range. Too little or too much of these hormones can cause blood sugar levels to fall too low (hypoglycemia) or rise too high (hyperglycemia).
Normally, blood glucose levels increase after you eat a meal. When blood sugar rises, cells in the pancreas release insulin, causing the body to absorb glucose from the blood and lowering the blood sugar level to normal. When blood sugar drops too low, the level of insulin declines and other cells in the pancreas release glucagon, which causes the liver to turn stored glycogen back into glucose and release it into the blood. This brings blood sugar levels to back up to normal.

A DNA sequence reads: TACGATCATATT. Which of the following is the correct complementary DNA strand?
ATGCTAGTATAA
AUGCUAGUAUAA
CGTAGCTGCGCA
GCAUCGAGUAUA
The complementary strand of a DNA sequence that reads TACGATCATATT is ATGCTAGTATAA.
Deoxyribonucleic acid (DNA) is made up of nucleotide subunits and functions in the storage of genetic information for living cells. There are four nucleotides that constitutes the DNA molecule namely: Adenine (A), Thymine (T), Guanine (G) and Cytosine (C).In a DNA molecule, adenine (A) base pairs Thymine (T) while Guanine (G) pairs Cytosine (C) i.e. A-T, G-C. According to this question, a DNA molecule with the following sequence was given: TACGATCATATT.

Which of these are cellular activities that sustain a single-celled organism through its lifetime? Select all that apply. The transmission of DNA to offspring, Processes by which individuals produce offspring, Development into a multi-celled adult, Increases in cell size and volume
Explanation:
The transmission of DNA to offspring.
Processes by which individuals produce offspring.
Increases in cell size and volume
A single-celled or 'unicellular' microorganism is a microscopic organism composed of only one cell. Unicellular microorganisms asexually reproduce to produce offspring.
The cellular activities that sustain a single-celled organism through its lifetime include:The transmission of DNA to offspringProcesses by which individuals produce offspringIncreases in cell size and volumeUnicellular microorganisms include, among others, prokaryotic bacteria, unicellular fungi (e.g., yeast), and unicellular protists (e.g., Amoeba).Reproduction refers to the process by which organisms transmit their genetic material (DNA) to offspring.In unicellular organisms, the process of reproduction is asexual (without the involvement of gamete formation).During their lifetime, unicellular organisms increase in size and volume to carry out their metabolic functions.In conclusion, unicellular organisms share different cellular activities which include the transmission of DNA to offspring, processes by which individuals produce offspring and increase in cell size and volume.Learn more in:

Which point is on the interior of ZBAC?

O point D
Opoint A

Opoint C
point B
Answer:
Point D.
Explanation:
A shape's internal angle is referred to as an interior angle. An external angle is any angle that is outside of a form.
What is Interior angle?One of the shape's lines is extended past the intersection point to create an external angle. Two angles combine to form a straight line.
This is significant because it indicates that, given the measurement of the other angle, we can always obtain the measure of the missing angle because we know that a straight line measures 180.
For instance, the rhombus below only provides us with an outside angle measurement. An interior angle is any angle that is located within of a form. An external angle is any angle that is outside of a form. One of the shape's lines is extended past the intersection point to create an external angle.
Therefore, A shape's internal angle is referred to as an interior angle. An external angle is any angle that is outside of a form.

based on patterns in the periodic table which element is the least malleable in its solid state
A.phosphorus (P)
B. strontium (Sr)
C. antimony (Sb)
D. copper (Cu)
Answer:
The metals having malleable property can be rolled or beaten into sheets.
Metallic bonds are very covalent that is, they share electrons among nuclei.
copper metal is a good conductor of electricity.
Pure Copper is soft, malleable and ductile.
i think so D.copper (Cu) is correct or more appropriate
Explanation:
The correct answer is option D. copper (Cu)
Malleability is the ability of metals to be hammered into sheets.
Metals are often required for different applications. The ability of metals to be hammered into sheets is called malleability.
Malleability of a metal is closely related to its density. The denser the metal, the less easily malleable it is.
Both copper and strontium are metals but copper is denser than strontium hence copper is less malleable than strontium.
