A person pushes the same box with the same amount of force on 3 different surfaces. Which surface exerts the least friction on the box?
*WRITE AS A CER*

Answers

Answer:

Read explanation

Explanation:

Surface C exerts the least amount of friction on the box. Evidence that proofs this claim is that the length of time it took the box to stop is greatest compared to surfaces A and B. The box and the amount of force added is the same for each surface test. It would take the box less time to come to a stop the more friction there is upon the surface.  Surface A having the quickest stop time meaning it has the most friction and C having the most time showing that it has the least amount of friction. In conclusion, surface C exterts the least amount of friction on the box.

Identify the biotic factors in the environment

shown. Check all that apply.

Answers

Complete question:

Identify the biotic factors in the environment shown. Check all that apply.

1) people

2) grass

3) rocks in the mountains

4) nylon tent

5) wooden kayak

Answer:

1) people

2) grass

Explanation:

The ecosystem is composed of living and non-living things that interact and depend on each other. These are the biotic and abiotic factors.

Abiotic factors are physical and chemical components of the ecosystem. These are the non-living elements. Biotic factors are all the living components in the ecosystem.  

Biotic and abiotic factors influence the survival and reproduction of living beings. They are related and in constant interaction. If one of these components is removed, the whole ecosystem will change because its equilibrium has been altered.  

Every abiotic component influence organisms and their survival and reproductive rates.

A few examples of the abiotic factors are solar light, minerals, water, air, gases, soil, and humidity.

Examples of biotic factors are plants, animals, insects, microorganisms, etc.

-------------------------------------------------------------------------------------------------------------

The biotic factors of the provided list are:

People, which is a group of individuals composed of cells -which is the basic unit of life-. They grow, reproduce and survive. Grass, as one or many species of vegetables that are also multicellular. They grow, reproduce, and survive.

The abiotic factors are:

Rocks, which are non-living things composed mainly of mineralsTent, which is also a non-living thing, is artificially made by humans.

In my opinion, the wooden kayak is a gray zone, meaning that it might be confusing. A kayak is an abiotic element with no life and is built by men. But it is constructed of wood. The wood originates in trees that are living beings, they are composed of cells, and they used to be alive. However, when talking about the kayak wood, we are referring to dead tissue. It is not alive anymore. Its cells are dead so, their whole system is not working. It is now composed of minerals and other elements with no life, and it has been modified and processed to build the kayak.

So my opinion is that the wooden kayak is an abiotic factor.

If haploid for an organism is 30 individual chromosomes, how many individual chromosomes would a somatic cell for this organism possess?
a. 15
b. 10
c. 90
d. 60
e. 30

Answers

A somatic cell for this organism would possess 60 individual chromosomes. Therefore, the correct answer is d. 60.

If the haploid number of chromosomes for an organism is 30, it means that each gamete (sex cell) of that organism contains 30 individual chromosomes. Gametes are haploid cells, meaning they only have one set of chromosomes.

In contrast, somatic cells are diploid cells, meaning they contain two sets of chromosomes. The diploid number of chromosomes is typically denoted as 2n. Therefore, to determine the number of individual chromosomes in a somatic cell, we multiply the haploid number (n) by 2.

For the given organism with a haploid number of 30 individual chromosomes, a somatic cell would possess:

2n = 2 * 30 = 60 individual chromosomes.

1. What conditions might cause the most water and sediment to be collected at the bottom of the stream table?

Answers

Answer: Steep, high velocity, no silting. The high water speed picks up silt from the bottom instead of letting it settle to the bottom. When the land gets level like often happens at the mouth of rivers where the water spreads out and slows down, silt settles to the bottom and you could get a wide, shallow delta.

Transcription of the trp operon is decreased when tryptophan interacts with the _____
- co-repressor
- repressor
- inducer
- promoter
- operator

Answers

Transcription of the trp operon is decreased when tryptophan interacts with the repressor, option B is correct.

When tryptophan interacts with the repressor protein in the trp operon, it forms a complex that binds to the operator region. This binding prevents the RNA polymerase from accessing the promoter region, thereby decreasing transcription of the trp operon.

The repressor protein is normally inactive in the absence of tryptophan. However, when tryptophan levels are high, tryptophan molecules bind to the repressor, causing a conformational change that enables the repressor to bind to the operator. This binding effectively blocks the RNA polymerase's access to the promoter, inhibiting the transcription of the trp operon, option B is correct.
