Answer 1

0.87 g/ml
Explanation
Density is mass divided by volume D = M/ V
D = 43.5g/50ml = 0.87 g/ml

Density D = 2.5 g/ml
Volume V = 15ml
Mass M = DV = 2.5 x 15 = 37.5 g

Density D = 5.45 g/ml
Mass M = 65 g
Volume V = M / D = 65 / 5.45 = 11.93 ml

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.

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)

Answers

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.

Which step in cellular respiration produces the most ATP?(1 point)

Krebs cycle

glycolysis

electron transport chain

lactic acid fermentation

Answers

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.

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.

Answers

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 volume

Unicellular 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.

Write a response that compares the perspectives of two groups of people using details from the article.Massachusetts Bay - The City Upon a HillMore than a thousand Puritans on 11 ships left England in 1630. The Puritans were fed up with the Church of England. They felt they couldn't practice their religion in England. The king of England didn't like the Puritans much either. So, he gave them permission to set up colonies in New England. The Puritans landed in the area of Massachusetts. John Winthrop was on one of those ships. He knew England would be watching them to see how they did. He wrote, "We shall be as a city upon a hill, the eyes of all people are upon us." Winthrop later became governor of Massachusetts.Puritans believed in predestination, which taught that God is all-powerful and all-knowing. So, each person is known to God at birth, and nothing a person can do or say could change his future. Not everyone could be a Puritan Church member. Only those chosen by God to be "saved" could be Church members. A person must see and feel the grace and power of God, so then he knows he is "saved." During the early years, ministers such as John Cotton made sure people were really "saved."The colony needed more than the "saved" people to survive. There were many dissenters, or Christian men and women who were not "saved." These people had jobs in business which were needed for the colony to survive.There was also a need for elected leaders that made laws. Ministers were not allowed to run for office. But many of the most important decisions were made by them. Puritan lifeAlmost 14,000 more Puritans came to Massachusetts from England in the next few years. So the colony began to spread out across New England. People began to live longer and healthier lives. It was often said that New England invented grandparents, which meant many people grew old enough to see their children have children. Puritans wanted their children to be able to read the Bible, so every town, with at least 50 families, built schools.Massachusetts Bay was a man's world, and women could not speak at town meetings or vote. Puritans believed women who were pregnant with a male child had pink cheeks, and those having a female child had pale cheeks. Names of women included Patience, Silence, Fear, Comfort and Be Fruitful, which shows what Puritans thought about women. Everyone went to church. People had to pay fines if they missed services. The minister's sermon or speech was about town problems. Often a man held a long pole to wake people or push children who were laughing. Church was very serious. Puritan dissentThe Puritans believed they were doing God's work. Those who sinned and did not do God's work were punished. Some could be put in jail. Others were whipped or brought to the public square in the center of town, where people would spit on them. Some were even killed.People were not free to think for themselves. Some free-thinkers could be forced to leave their homes and never return. Roger Williams and Anne Hutchinson were two free-thinkers who spoke their minds and were sent away.Roger Williams believed in the separation of church and state. He said churches should not get money from the taxes leaders of the town government collected from the people. Williams also said the Native Americans were not paid enough for their land. Massachusetts banished him from his home in 1636. Williams bought some land from the Narragansett Indians and started the colony of Rhode Island, where people could be free thinkers. Anne Hutchinson believed in predestination, which taught that God is all-powerful and all-knowing. She said it was God who controlled the future, not the rules of the church. Puritans believed this, but she said the ministers were actually teaching people they could do things to get into heaven. She also said people who were "saved" didn't have to follow the law. Sometimes 80 people would come to her home each week to hear her sermons. The ministers decided to arrest her, and the court found her guilty. She was banished and moved to Rhode Island, too. Roger Williams and Anne Hutchinson were two brave souls who told people they have the right to disagree.There is another side of Puritan life that is not well known. They did have some fun, too. People sang and told stories. They drank wine and beer. Children were allowed to play games with their parents' permission. Puritans did not all dress in black as many believe. They tried to follow God's law. People who did what the ministers said, lived in peace. what is the range of the numbers 5,9,7,2,2 Rewrite the expression in the form b^n b^10b^6= please help me solve that question i need a little help here, im struggling rnn Name the Special Economic Zone (SEZ) which is in the Free State province.
