Gold is opaque and reflective. It has a _____.-glassy luster
-metallic luster
-dull luster
-pearly luster

Answers

Answer 1

Answer:

Answer: The correct answer for the fill in the blank is metallic luster.

Gold is a metal. Thus, it possesses all the properties of metal like ductility, malleability, conduction of heat and electricity, metallic luster.

When the light interact with the surface of gold, it produces brilliant shine. This shine is referred to as its metallic luster.

Gold is opaque and reflective. When light strikes gold surface, it is reflected back and does not pass through gold.

Thus, the correct answer for the fill in the blank is metallic luster.

Answer 2

Answer: Gold has a metallic luster. Go panning for gold in a river bed...those little flakes catch the sun in such a way that you KNOW it is gold. A dull luster would not show this.

Breathing hard during exercise brings oxygen to your muscles, which helps what process release energy to fuel your workout

Answers

This statement is a fact: "Breathing hard during exercise brings oxygen to your muscles, which helps what process release energy to fuel your workout."
This is because..............
>During exercise, your muscles have to work harder. Working harder increases their demand for oxygen, which is why your breathing and heart rates increase, to pull more oxygen into the bloodstream.
> The oxygen that reaches your muscles never leaves as you exercise, but rather sets to work immediately converting the available glucose into ATP.

Answer:

The correct answer would be cellular respiration.

Oxygen in muscles helps in completing the process of cellular or aerobic respiration.

By this process, the carbohydrate (glucose) is completely broken down in presence of oxygen.

This process is used by the cell to produce energy or ATP which helps in fueling the workout.

One molecule of glucose is used to produce 36-38 molecules of ATP in presence of oxygen.

how many copies of each chromosome are contained in each of the daughter cells resulting from meiosis?

Answers

Each daughter cell has 23 of the 46 chromosomes. Sister chromatids make up each chromosome. Daughter cells enter meiosis II, the final step. Two haploid cells result from meiosis I.

What is meiosis?

Meiosis is a specialized kind of cell division that occurs in the germ cells of animals that reproduce sexually. This form of cell division is responsible for the production of gametes, such as sperm and egg cells. This process requires two rounds of cell division, and at the end of it, there are four cells that each have a single copy of each chromosome.

There are 46 chromosomes total, and each daughter cell has 23 of them. Each chromosome is composed of two sister chromatids. In the second and last stage of meiosis, daughter cells participate. Meiosis I always results in the formation of two haploid cells.

Answer:

Each daughter cell will have half of the original 46 chromosomes, or 23 chromosomes. Each chromosome consists of 2 sister chromatids. The daughter cells now move in to the third and final phase of meiosis: meiosis II. At the end of meiosis I there are two haploid cells.

Which of the following statements is TRUE?

Answers

Answer:

B: Hyperosmotic solutions may cause the cell to shrink.

Explanation:

Final answer:

The first statement is false because it inverses the concepts of potential and kinetic energy. The second statement is true, and the electric field is indeed analogous to the gravitational field. The third statement is false since voting rates in the U.S. are not higher than in most other democratic industrialized countries.

Explanation:

The answers to those statements are as follows:

False. The statement is incorrect because it inverses the concepts of kinetic and potential energy. When a rock is thrown into the air, its height increase adds to its potential energy, not kinetic energy. When it starts falling back to the ground moving faster, its velocity increase adds to its kinetic energy.
True. This statement is correct. The characteristics of an electric field indeed make it analogous to the gravitational field near the surface of Earth. Both fields decrease in intensity with the square of the distance from the source.
False. Voting rates in the United States are not higher than in most democratic industrialized countries including Sweden and South Korea. In fact, other industrialized countries often have higher voter turnout rates than the U.S.
