A scientist wants to determine the best light wavelength for growing plants. He grows plants in four test groups as shown in the table below. What, if anything, was wrong with the experiment?

A. He should only grow one plant in each group.
B. He should only change the wavelength of light for each group.
C. He should add a control group with a CO2 level of zero ppm and a light intensity of zero percent.
D. There is nothing wrong with the experiment.

Answer:

D. this is why but if it's wrong sorry ;)

Some materials are better conductors than others and offer less resistance to the flow of charge. Silver is one of the best conductors but is never used in wires of household circuits due to its cost.

Answer:

The type of chromosomes based on the position of centromere are of the following four types :

1) Metacentric chromosome: centromere in middle forming two equal arms.

2) Sub-metacentric chromosome: centromere placed near to one end resulting in one shorter and one long arm.

3) Acrocentric chromosome: Centromere placed close to one end forming one extreme short and one extreme long arm.

4) Telocentric chromosome: terminally placed centromere.

Answer:

Metaphase

Explanation:

The metaphase is when chromosomes are lined up and each sister chromatid is attached to a spindle fiber, which will place all of the chromosomes in the proper place in the cell.

Answer:

D.) Metaphase i took the quiz

Answer:

A. is the organism able to respond to stimuli

Explanation:

The determination of whether to classify an organism in kingdom Plantae or kingdom Animalia is the organism able to make its own food or not. Thus, the correct option is B.

The main defining characteristics between the organisms of Kingdom Plantae include all the multicellular, photosynthetic eukaryotes category. Plants belong to the kingdom Plantae. Plants are the primary producers of the Earth’s ecosystem. They can prepare their own food (carbohydrates).

The characteristics of the Kingdom Animalia include the organisms which belong to the category of multicellular, eukaryotes. They are classified into various classes such as mammals, amphibians, reptiles, fish, birds, and insects. They cannot prepare their own food. They can move from one location to the other location.

Therefore, the correct option is B.

In the given image, it is showing that plants use carbon dioxide gas to make sugars during photosynthesis. The correct option is D.

The carbon cycle is nature's method of recycling carbon atoms, which travel from the ambience into Earth's living organisms and then back into the atmosphere. The majority of carbon is stored in rocks and sediments, with the remainder in the ocean, environment, and living organisms.

Plants consume carbon dioxide and sunshine during photosynthesis to produce fuel i.e., glucose and other sugars for the construction of plant structures. The fast biological carbon cycle is built on this process.

Thus, the correct option is D.

Answer:

Each organism has a basic unit of structure which are cells.

Explanation:

;)

Cells are regarded as the fundamental units of life in part because they come in discrete and easily identifiable packages.

Cells are the fundamental building blocks of all life. Trillions of cells make up the organisms' body.

They support the body's structure, absorb nutrients from food, convert those nutrients into energy, and perform specialized functions.

Nucleic acids, proteins, carbohydrates, and lipids are the four major classes of organic molecules found in all cells.

Cells are regarded as the fundamental units of life in part because they come in discrete and easily identifiable packages.

Like the walls of a house, all cells are surrounded by a structure called the cell membrane, which serves as a clear boundary between the cell's internal and external environments.

Thus, cells are the basic unit of structure of all organisms.

An endotherm is an organism that uses internal body heat to maintain a metabolically suitable temperature rather than relying on ambient heat. The endotherms primarily include the birds and mammals.

In contrast to organisms that rely on the heat of their surroundings to sustain a temperature that is optimal for their metabolic processes, endotherms generate their own heat from within their bodies. The majority of endotherms are comprised of different kinds of birds and animals.

Endotherms, which include birds and mammals, generate and store a significant amount of heat within their own tissues, as opposed to ectotherms, which include insects and reptiles, who take in heat from their surroundings. Insects and reptiles are examples of ectotherms.

Answer:

the kind of material it is moving through

Explanation:

Sound wave is a type of mechanical wave, which requires a medium to travel, unlike longitudinal waves that can travel through vacuums. Since, sound waves travel through mediums, the KIND OF MEDIUM/MATERIAL it is traveling through has a role to play on how fast it moves.

Sound waves move faster in materials whose molecules are closely packed together than those with loosely packed molecules. This is why sound waves naturally travel faster in SOLID materials. Therefore, the the kind of material the sound wave is moving through affects how fast it moves.

These connections occur at short, root-like tendrils called dendrites, which sprout from the neuron's cell body, or soma. ... As it loses input connections, the wounded neuron also becomes more excitable: the neuron becomes more likely to fire signals down its truncated axon when stimulated to do so by other neurons.

Answer:

See the answer below

Explanation:

The greenhouse effect refers to the heating effects produced by the earth's atmosphere on the planet as a result of the atmosphere absorbing reflected radiation from the sun by the earth.

The earth's atmosphere is a blanket of gases, some of which are referred to as greenhouse gases. These gases have the capacity to trap radiations coming from the sun that is reflected by the ground layer of the earth. Thus, they produce a warming effect on the earth.

A bulk of the radiation coming from the sun is reflected back into space by the earth's stratosphere. The small percentage that passes through are dispersed in different directions and some of them pass through the atmospheric blanket to reach the ground layer of the earth. While some are absorbed by the ground itself, some are emitted back into the atmosphere where the greenhouse gases trap a large portion and prevent them from escaping back into space.

This leads to the warming of the earth and the entire phenomenon is referred to as the greenhouse effect.

Answer:

1.732 seconds

[tex]s=ut+\dfrac{1}{2}at^2[/tex]

Explanation:

s = Displacement of ball = 15 m

g = a = Acceleration due to gravity = [tex]10\ \text{m/s}^2[/tex]

u = Initial velocity of the ball = 0

t = Time taken

From the kinematic equations we use the following formula

[tex]s=ut+\dfrac{1}{2}at^2\\\Rightarrow 15=0t+\dfrac{1}{2}\times 10t^2\\\Rightarrow t=\sqrt{\dfrac{15\times 2}{10}}\\\Rightarrow t=\sqrt{3}=1.732\ \text{s}[/tex]

The object will reach the ground after 1.732 seconds.

The formula used is [tex]s=ut+\dfrac{1}{2}at^2[/tex].

Answer:

In the crossing of individuals with multiallelic traits, the crossing of a GGHHII individual with a gghhii individual would produce offspring of hybrid individuals for all three traits whose genotype would be GgHhIi (option c).

Explanation:

The individuals GGHHII and gghhii are pure lines for each of the traits —multiallelic traits— they express, one of them having the three dominant traits and the other three recessive traits. The product of crossing two pure lines with dominant and recessive traits is an offspring of 100% heterozygous individuals.

This can be tested by making a Punnett square for this cross:

GGHHII X gghhii

Alleles     GHI        GHI

ghi         GgHhIi   GgHhIi

ghi         GgHhIi   GgHhIi

Thus the offspring in the cross of two individuals, dominant and recessive, for multiallelic traits G, H and I is GgHhIi
