To model ocean water in different places on Earth, a student pours equal amounts of water in two containers. He adds the same am

ount of salt to each container and stirs until the salt is completely dissolved. He places Container 1 in a cool place in the house and Container 2 outside in the sunlight. After two hours, he tests the salinity of water in each container. What should the student MOST LIKELY conclude, and why?

Answer:

The correct answer would be - container 2 will have less salinity than container 1.

Explanation:

The given experiment can give an idea about how the temperature of surroundings can affect the salinity, volume, and density of the water that has the same amount of water and salt dissolved in it. The independent variable or the only variable that is different is their place that has a difference in the temperature. Container 1 is placed in a cool place while container 2 is placed in sunlight.

We know that the warmer the water it takes more space so, therefore, less density. Density and salinity both have a positive relationship so an increase in density increases the salinity and vice versa. Thus, here the salinity of container 2 would be low in comparison to container 1

The dependent variable being measured in the preceding plant experiment, “How Plants Grow In Response to Light,” is the plant's growth. The independent variable is how the plant grows in response to variations in the amount of light it receives.

<h3>What is florist hypothesis?</h3>

The independent variable is how the plant grows in response to variations in the amount of light it receives.

Determine the variable that will be altered first. In this instance, the plant's exposure to light is altered. The independent variable is this.

A clear, explicit, testable assertion regarding the expected relationship between variables or the explanation for an event is called a research hypothesis (or scientific hypothesis).

Therefore, plant growth, hormone concentration, shoot and root, floral pattern development are the part of data in the hypotheses.

Proteins that affect the structure of dna bound to histones without altering histone chemical structure are called:_______
slamgirl [31]

Proteins that affect the structure of dna bound to histones without altering histone chemical structure are called Non-histone protein.

The proteins that remain after the histones have been taken out are known as non-histone proteins. A large group of heterogeneous proteins referred to as non-histone proteins organise and compress the chromosome into higher order structures.
They play a crucial role in regulating processes such nuclear transport, steroid hormone activity, nucleosome remodelling, DNA replication, RNA synthesis and processing, and the transition between interphase and mitosis.
Scaffold proteins, DNA polymerase, Heterochromatin Protein 1, and Polycomb are examples of typical non-histone proteins. This classification area also includes a large number of other structural, regulatory, and motor proteins. Non-histone proteins can be acidic. Other than histones, many proteins have the ability to bind to DNA and change the shape of the chromatin by means of epigenetic processes.
