An airtight, temperature-controlled glass box containing actively growing tomato plants was placed under a light source. Plastic wrapping that only transmits green light was placed over the box, and two days later air samples from inside the box were collected and analyzed. The most likely change in air quality is:

Answers

The most likely change in air quality is a decrease in carbon dioxide (CO2) present in the box.

Photosynthesis is the process by which green plants produce their own food in the presence of light and carbon dioxide. The most important indicator of air quality is carbon dioxide. This gas is removed during photosynthesis.

This implies that after two days, analysis of the air samples from the pot will definitely indicate a large decrease in the amount of carbon dioxide present in the box.

A. Reinforcement and support C. Elasticity
B. Exchange of gases D. Formation or root hairs

Answers

Reinforcement and support

parenchyma, in plants, tissue typically composed of living cells that are thin-walled, unspecialized in structure, and therefore adaptable, with differentiation, to various functions. The cells are found in many places throughout plant bodies and, given that they are alive, are actively involved in photosynthesis, secretion, food storage, and other activities of plant life. Parenchyma is one of the three main types of ground, or fundamental, tissue in plants, together with sclerenchyma (dead support tissues with thick walls) and collenchyma (living support tissues with irregular walls).

What are the four most common elements in all living things

Answers

Answer:

Oxygen

Oxygen is the most abundant element contained within living organisms, composing about 65% of the human body. Oxygen is also the most abundant element in the Earth's crust, and in the air that is essential for most life on Earth. Oxygen's presence in the body is largely in the form of water, which is used to produce the energy within the body needed to sustain life.

Carbon

Carbon forms the basis for all life on Earth; indeed, life forms on Earth are referred to as carbon-based life forms, emphasizing the importance of this element for life. Carbon atoms readily bond to other atomic elements, such as oxygen and nitrogen. Since carbon can so readily bond to other elements, long chains of bonds can form and provide the physical and chemical structure needed for the complex processes and structures that occur within living organisms, such as structural proteins and genetic information in the form of nucleic acids.

Hydrogen

Hydrogen is the simplest element, as its atom contains only a single proton and a single neutron. As a result of this simplicity, hydrogen readily bonds with other elements, making it an important component for the formation of living organisms. Hydrogen is the other element (along with oxygen) which forms water, a crucial component for most life forms on Earth. Hydrogen is also a byproduct in many biological reactions, including photosynthesis and metabolism.

Nitrogen

Nitrogen is one of the most abundant elements on Earth, composing approximately 80% of the air on Earth. Nitrogen is an important element in the development of plant life, as compounds containing these elements are readily absorbed and used by plants. Nitrogen is also an important component of many proteins and deoxyribonucleic acids (DNA), which is crucial for genetic material to be passed on to subsequent generations of life.

Sulfur

Sulfur is a major component of two essential amino acids used by living organisms: cysteine and methionine. These amino acids, like all amino acids, are crucial for the construction of proteins that are used for structural stability and repair of living organisms. For example, the structural integrity of hair and feathers can be attributed to these amino acids. Sulfur is also used as a source of energy and is metabolized by some species of bacteria and other lower life forms.

Phosphorus

Phosphorus is used in the formation of phospholipids, a type of molecule that is a major component of the cell membrane of all living cells. Without this cell membrane, cells would not be able to develop and would not have the structural stability to form in the first place. This protective layer of phospholipids holds all the internal components of cells in place, allowing for the processes that maintain the life of the cell to take place. The phospholipid layer also protects the cell by keeping any unwanted or potentially destructive materials outside of the cell.

The independent variable should stay constant because  each group should be completely different to do an experiment while it is being conducted.

What are variables?

The variables are defined as any characteristics, number or quantity which can be measured . They can also be called as a data item . They are called as variables because they can vary and can have variety of values.

There are three types of variables 1) manipulated variable where in a condition is specified, 2) responding variable which is dependent on manipulated variable 3)controlled variables which does not change

Example of manipulated variables are number of hours spent by a student studying , that of responding variable is result of a student and temperature is an example of controlled variable.

Explanation:

Environmental factors typically activate genes in a cell by causing the cell to --
A.produce identical daughter cells through mitosis
B.form haploid gamete cells through meiosis
C.fuse with another cell to increase the size of its genome
D.transcribe specific DNA segments to mRNA for translation

Answers

Environmental factors typically activate genes in a cell by causing the cell to transcribe specific DNA segments to mRNA for translation.

This interaction is an example of environmental factors affecting genetic expression. In these situations, the environment causes specific segments of DNA to be expressed, meaning they are transcribed to mRNA and subsequently used to form proteins.

Meanwhile, other parts of the genome remain or are forced to be silent. This can be a result of mutations or simple biochemical reactions between the environment and the genome.
