A student wants to perform an experiment to test the effect of different colored lights on the growth of basil plants. She sets up an experiment where multiple basil plants are placed in six different setups; one with red light, one with green light, one with yellow light, one with blue light, one with no light and one with sunlight. In each setup the plant receives the same amount of water, soil, and size of container. What is the independent variable in this experiment

Answers

Answer 1

Answer:

light is the independent variable, height of the plant is the dependent variable. Dependent is the effect that based on the independent.

Explanation:

lets break it down. 1) you want to know the effect of something you apply from one thing to another. Let say, if you grow your plants under the sunlight, the plants grow taller. In this case, the sunshine is the independent variable whereas the height of the plant/how tall it can grow is the dependent variable. 2)NOW, before i give the answer. The design of the question is not good for high school students. i think your teacher thinks "light" is the independent variable. 3)However, the question contains confounding variables in it because different lights might produce different effects to the height of the plants. If you want to test if plants are exposed to light grows taller than plants do not expose to light, then you should have all the lights are the same. 4) So, all the plants should be exposed to one certain light to avoid confounding. Confounding means that either red light and sunlight are both produce the same effect whereas the other colors do not help the plants to grow taller. 5)Your teacher should test one light at a time. So, if he is testing with all different colors of light, then light is the independent variable, and height of the plant is the dependent variable.

Answer:

Look at explanation

Explanation:

An allele is one of two or more versions of a gene. An individual inherits two alleles for each gene, one from each parent. If the two alleles are the same, the individual is homo-zygous for that gene. If the alleles are different, the individual is hetero-zygous.

Can someone please help me with these two:
1. Blood is at it's highest pressure just when it leaves the heart. Why do you think so?
2. The blood in an artery flows faster and at higher pressure than blood in veins. Why so?

Answers

Answer:

1.Blood pressure can be defined as the pressure of blood on the walls of the arteries as it circulates through the body. Blood pressure is highest as its leaves the heart through the aorta and gradually decreases as it enters smaller and smaller blood vessels (arteries, arterioles, and capillaries).

2. The more rounded the lumen, the less surface area the blood encounters, and the less resistance the vessel offers. Vasoconstriction increases pressure within a vein as it does in an artery, but in veins, the increased pressure increases flow.

Decomposers are important in the environment because they
A. convert large molecules into simpler molecules that can then be recycled
B. release heat from large molecules so that the heat can be recycled through the ecosystem
C. can take in carbon dioxide and convert it into oxygen
D. convert molecules of dead organisms into permanent biotic parts of an ecosystem

Answers

Answer:

D

Explanation:

Decomposers are important in the environment because they convert molecules of dead organisms into permanent biotic parts of an ecosystem. So, the correct option is (D).

What are Decomposers?

Living organisms such as micro-organisms that convert dead plants and animals into humus are known as decomposers. Fungi and bacteria fall in this category. It recycles and converts the dead matter into humus which mixes with the soil of the forest. It provides essential nutrients to the plants. It is also known as detritivores.

There are four types of decomposers, namely

FungiInsectsEarthwormBacteria

These types of organisms decompose or break down organic matter such as the remains of dead organisms, carrying out the process of decomposition, which occurs after the death of all living organisms.

They are also called reducers because they are able to remove or degrade dead bodies of organisms and because of their small size they are known as micro consumers.

Thus, Decomposers are important in the environment because they convert molecules of dead organisms into permanent biotic parts of an ecosystem. So, the correct option is (D).

Farmer Brown notices his tomato plants are leaning towards the front, which results in spoiling tomatoes. Briefly explain to Mr.
Brown what method he can
use prevent that from happening​

Answers

Answer:

Install wood or rebar stakes at least 6 feet-tall at planting time. As the plants grow, tie the stems loosely to the stakes with twine or strips of fabric.The most common cause of leggy seedlings is lack of strong, overhead lighting. Tomato plants become long and spindly when they are reaching for the light. If the light only comes from one direction, then your seedlings not only become leggy, but will also lean towards the light.Generally speaking, in the north, tall plants such as beans, peas, and corn do best on the north side of the garden. Medium size crops such as tomatoes, cabbage, squash, pumpkins, and broccoli in the center of the garden.

You are walking through a mixed evergreen-deciduous forest, where approximately 10 percent of the trees are eastern hemlocks, a species of evergreen tree that casts very deep shade on the forest understory. Interestingly, under every eastern hemlock, you find the same small herbaceous plant species. However, you never observe this species anywhere else, even though a healthy diversity of other species live throughout the forest understory. You expect the small herbaceous species to have _____ growth, _____ sexual maturity, _____ energy expended on seeds, and _____ reproduction. Please choose the correct answer from the following choices, and then select the submit answer button. Answer choices fast; early; high; no vegetative slow; late; low; vegetative slow; early; low; vegetative fast; early; low; vegetative slow; late; high; no vegetative

Answers

Answer: slow; late; low; vegetative

Explanation: Due to the casting of deep shade on the forest understory by eastern hemlock, direct sunlight and other necessities for photosynthesis and other life processes needed by the herbaceous plant species for optimum growth is being deprived.

However, coupled with the nature of these herbaceous plant species, having non-woody stems with their growth above the ground level often dieing off particularly in winter in the temperate zone, makes their growth in that kind of location to be stunted.

Thus, herbaceous plant species with slow growth rate leading to late sexual maturuty while having low expanded energy on seeds due to low photosynthetic rate and low vegetative reproduction should be expected.

Explanation:

Chlorophyll is the green pigment that absorbs the light energy for photosystems.

The substance in chloroplasts that is a green pigment and absorbs energy for photosystems is chlorophyll, which is present in Option C, as chlorophyll is the primary pigment responsible for the green color of most plants as it reflects green light,

What is chlorophyll?

Chlorophyll is a type of pigment that is responsible for the green color of leaves, stems, and other plant parts, and it is found in the chloroplasts of plant cells, specifically in the thylakoid membranes, where it plays a central role in photosynthesis, and chlorophyll absorbs light energy from the sun. During photosynthesis, chlorophyll absorbs light energy and transfers it to other molecules in the photosystems, where it is used to generate ATP and NADPH, and these energy-rich molecules are then used in the light-independent reactions of photosynthesis to produce glucose and other organic compounds.

Hence, the substance in chloroplasts that is a green pigment and absorbs energy for photosystems is chlorophyll, which is present in Option C.
