B. 100 grams
C. 130 grams
D. 160 grams

Answers

Answer 1
Answer:

Answer:

correct option is C. 130 grams

Explanation:

solution

as carbohydrate is a macro nutrient that is found in many foods and beverage

Most of carbohydrate occur in plant base food

some main natural source of carbohydrate are

  1. vegetable
  2. fruit
  3. nuts
  4. milk
  5. grain
  6. seeds

and for adult age of 19 years to 30 years carbohydrate need is 130 grams per day

and adult male age of 19 years to 30 years fiber need is 38 grams per day

and adult female age of 19 years to 30 years fiber need is 25 grams per day

so correct option is C. 130 grams

True or False: The density of a specific type of material never changes.

Answers

The statement 'the density of a specific type of material never changes' is TRUE.

  • The density of a substance/material is a measurement that describes the relationship between mass and volume.

  • The density can be easily calculated by dividing mass by volume (d = M/V, where d describes density, M is equal to mass, and V is equal to the volume).

  • Density is considered as an intensive property, thereby this value does not change as the amount of a given material/substance changes.

In conclusion, the statement 'the density of a specific type of material never changes' is TRUE.

Which three organization levels are in a human stomach?Muti choice
1) cell
2)organ
3)organ system
4)organism
5)tissue

Answers

Answer:

Cell, tissue, and organ.

Explanation:

A cell is an obvious one because it makes up the tissue, and it is needed in order to form an organ. Meaning tissue and cell would have to be included. Tissues witch are made of many cells form an organ, and an organ would be  the human stomach/digestive system. It can't be organ system because a stomach can't be a whole system including the heart and ect. It can't be organism because a stomach isn't enough organ systems to create an organism.

Answer:

Cell Organ System Organ

Explanation:

cells make up everything as a building block of life.

What are physical properties? Give some examples.

Answers

Answer:

A physical property is any property that is measurable, whose value describes a state of a physical system. The changes in the physical properties of a system can be used to describe its changes between momentary states. Physical properties are often referred to as observables. They are not modal properties. Quantifiable physical property is called physical quantity.

Examples:

color (intensive)

density (intensive)

volume (extensive)

mass (extensive)

boiling point (intensive): the temperature at which a substance boils

melting point (intensive): the temperature at which a substance melts

Answer:

A physical property is a characteristic of matter that is not associated with a change in its chemical composition. Familiar examples of physical properties include density, color, hardness, melting and boiling points, and electrical conductivity.

How do you feel about the results of this activity? Were you surprised? Why or why not?

Answers

The results of an activity or experiment can either prove or disprove the initial hypothesis. Also, if they disprove the initial idea or hypothesis they are surprising.

In any activity or experiment, the results are always related to the first idea or hypothesis. In this way, the results can:

  • Match or prove the initial idea
  • Contradict or disprove the initial idea

For example, if the initial idea is "Plants require 10 ml of water to survive" by the end of the experiment you will understant if this is true or if it is false.

Moreover, if the results do not match your initial idea, then they can be classified as revealing and surprising.

Note: This question is incomplete because the activity is not included; however, I answered this question based on general knowledge.

Use the template of a replication fork to draw arrows that represent both continuous and discontinuous DNA synthesis. Draw one long arrow to show continuous DNA synthesis and three arrows to show discontinuous DNA synthesis. The arrows should point in the direction of nucleotide addition, and the three arrows showing discontinuous synthesis should be numbered 1, 2, and 3, in the order of fragment synthesis.

Answers

Answer: seen below

Explanation:

Deoxyribonucleic acid (DNA) synthesis is the biological process by which DNA molecule is created. In the cell, each of the two strands of the DNA molecule acts as a template for the synthesis of a complementary strand. This strands are separated during replication (DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule). DNA polymerase synthesizes the new strands by adding nucleotides that complement each (template) strand.

Deoxyribonucleic acid (DNA) synthesis is continuous because extension of a single ribonucleic acid (RNA) primer occurs without interruption into the replication fork as it continues to open to the right as seen on the diagram below. On the upper lagging strand which is the discontinuous synthesis, here synthesis is discontinuous, since new RNA primers must be added as opening of the replication fork continues to expose new template.
