Answer:

Reproductive cells contain only four gene copy.

Explanation:

Inside the cell there are various kinds of cell component like Golgi apparatus, plasma membrane, endoplasmic reticulum, mitochondria. Therefore the mitochondria is the cell component functions like the digestive system converting food to energy in the human body. The correct option is option D

Cell is the basic unit of life. It is the smallest unit of any organ. different cell component have different role in the working of cell

According to our question

The role of Golgi apparatus is to deliver vesicles

The role of plasma membrane is to make ways for the transfer of material from inside to outside of the cell or vice versa

The role of endoplasmic reticulum is to synthesize the ribosomes

The role of mitochondria is to convert food to energy in the human body

Therefore the mitochondria is the cell component functions like the digestive system converting food to energy in the human body. Thus the correct option is option B

Answer:

1. It is confirmation bias because the company conducted a research experiment on their on products. They could have implemented or changed variables that are part of the experiment in order to get the results they would want. It is best to have a third party that don’t work for the company in order to conduct the experiment without biases

2. For this one it could be both yes and no. It could be that John really enjoyed Sports Drink A, so he purposely wrote down the data for the other drink lower. Here he was bias towards what he wants to have a better outcome. Maybe the sport drink A is from a company he likes many of their products. In order to not have confirmation bias, john should get a friend to give him the drinks without the labels, and the drinks should be the same color. That way he only tests the taste and not the way it looks. Both packaging and the color of the drink.

Answer:

observations (2), (3), and (4) provide strong evidence that a chemical reaction occurred.

Explanation:

Observations (2), (3), and (4) are evidence of a chemical reaction because a precipitate formed, energy was released (the bottom of the beaker felt warm), and bubbles were formed in the water. Observation (1) indicates a physical change, not a chemical reaction.

Explanation:

When using a screw to hang a picture, it is important to understand its function. The best description of a screw is option B - "A screw allows you to use less force because a screw acts like an inclined plane."

Screws are simple machines that have an inclined plane wrapped around a cylinder. This inclined plane is known as the thread. As the screw is turned, the thread pulls the screw into the material it is being screwed into, allowing it to hold on tightly.

Because of this design, screws are able to reduce the amount of force needed to hold an object in place. This is because the force applied to the screw is spread out over a larger area, making it easier to turn the screw and insert it into the material.

In conclusion, when using a screw to hang a picture or any other object, remember that it is an inclined plane wrapped around a cylinder, designed to reduce the amount of force needed to hold an object in place.

Answer: The answer is B! <3

Explanation:

When Blake puts a screw into his wall, it is a good description of an inclined plane. The threads of a screw act like an inclined plane to increase the distance over which you exert the input force. As the threads of the screw turn, they exert an output force on the wood, pulling the screw into the wood. So the answer is B. I hope this helped! :)

Answer:

4) Mixtures contain different substances with different properties and chemists can separate one item from the mixture by forcing it to undergo a chemical change.

Explanation:

Mixtures contain different substances with different physical properties, such as boiling point, melting point, solubility, density, and so on. These properties can be used to separate the individual substances in the mixture through various techniques. For example, distillation is a separation technique that relies on differences in boiling points of the substances in a mixture. When a mixture is heated, the substance with the lower boiling point will vaporize first, and it can be collected and cooled to form a pure substance. Similarly, other techniques such as chromatography, filtration, and crystallization also rely on differences in physical properties to separate mixtures.

On the other hand, chemical changes involve the rearrangement of atoms within a substance, resulting in the formation of a new substance with different properties than the original. While chemical changes can be used to synthesize new substances, they are not typically used to separate mixtures.

Magnesium hydroxide provides relief for indigestion by reacting with HCl to produce a solution that is neutral.

Magnesium hydroxide in the stomach acts as an antacid (i.e substance that neutralizes stomach acidity). They are utilized as laxatives for the sole purpose of treating constipation and increasing bowel movements.

When present in the stomach, magnesium hydroxide reacts with the HCl produced by the parietal cells that are present in the gastric glands to neutralize these acids and produce a solution that is neutral.

Independent Variable and the Dependent Variable

Explanation:

To conduct an expierement, you need at least one of each to collect data

The two columns on a data table represent the dependent  variable and independent variable.

Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis are the proper phases of the cell cycle. The series of actions that take place between the development of a mother cell and the production of two daughter cells is known as the cell cycle.

Interphase and cell division are the two main stages. The phase of the cell cycle known as interphase is when the cell develops and gets ready to divide. The initial stage of cell division, known as prophase, occurs when the nuclear envelope separates and the chromosomes condense.

The second stage of cell division, known as metaphase, is when the chromosomes align in the centre of the cell. The third stage of cell division, known as anaphase, is when the chromosomes split and migrate to the opposing poles of the cell.
