The answer is False.
The toxic gases released during fires are classified into two broad categories, asphyxiant gases such as cyanides, hydrogen sulfide and carbon oxides (carbon monoxide and carbon dioxide) resulting in central nervous system depression and gases. irritants such as chlorine and its derivatives, aldehydes and nitrogen derivatives causing caustic lesions of the respiratory mucosa. In total several hundred, toxic gases have been identified. It is therefore not possible to treat them all in this presentation, so only the most important by their dangerousness will be detailed.
During a fire, the oxygen in the ambient air is consumed by the combustion of the materials. In a confined space like a house or an apartment, its fall can be extremely fast not exceeding a few minutes.
Vascular tissue consists of xylem and phloem.
Explanation:
Vascular tissue could be a advanced conducting tissue, shaped of over one cell kind, found in vascular plants. the first parts of plant tissue are the vascular tissue and vascular tissue. These 2 tissues transport fluid and nutrients internally. The cells in plant tissue are generally long and slender
Phloem make up the vascular tissue. It helps in the transportation of the food prepared by the leaves of the plant.
Further Explanation:
Phloem is made up of vascular or livingtissue. It uses the turgor pressure that helps in the transportation of sugar to each part of the plants. It also supports the transportation of proteins and m RNA (messenger ribonucleic acid) to each region of the plants.
Phloem is composed of certain specialized cellssuch as sieve tubes, phloem fibers, companion cells and parenchyma cells. The phloem is divided into two types namely; primary phloem and secondary phloem. The primary phloem consists of the apical meristem. It is a region of new cell formation. It lies on the tip of root and shoot. It is further divided into two types; protophloem or metaphloem. The cell of Protophloem mature before elongation, whereas metaphloem mature after cell elongation. Secondary phloem resides in the plant that have a cambium.

Answer:
maintain homeostasis in eukaryotic cells.
Explanation: these are two roles in maintaining homeostatic in eukaryotic cells
1. Membrane Production: The rough ER is responsible for producing the phospholipids and proteins that make up the cell's membranes. These membranes are essential for compartmentalizing the cell and regulating the movement of substances in and out of the cell. For example, the rough ER helps in the production of the plasma membrane, which controls the exchange of molecules between the cell and its environment.
2. Protein Production: The rough ER is studded with ribosomes, which are responsible for protein synthesis. The ribosomes on the rough ER synthesize proteins that are destined for secretion, insertion into the cell membrane, or transport to other organelles. These proteins undergo folding and post-translational modifications in the rough ER, ensuring their proper structure and function. For example, the rough ER produces enzymes that aid in digestion and hormones that regulate various body functions.
By facilitating membrane and protein production, the rough ER helps maintain the integrity, structure, and function of eukaryotic cells. Without these processes, cells would not be able to carry out essential functions, leading to cellular dysfunction and potential health issues.
The rough ER's main function is to synthesize and modify proteins destined for the cell membrane or for export from the cell, a process that is crucial in maintaining homeostasis in eukaryotic cells. This protein synthesis and distribution are crucial for cells' life, growth, and responses to the environment.
The primary function of the rough ER is the synthesis and modification of proteins that are destined either for the cell membrane or for export from the cell. This process is aided by ribosomes that attach to the ER, giving it a rough appearance. The produced protein is typically synthesized within the ribosome and then released inside the channel of the rough ER, where sugars can be added to it (glycosylation) before it is transported within a vesicle to the next stage, the Golgi apparatus.
This protein synthesis by the rough ER plays an important role in maintaining homeostasis in eukaryotic cells. It helps ensure the cell has the required proteins to function properly and influences the balance of protein production and distribution, crucial for cell life, growth, and responses to the environment.

Answer:
Control group
Explanation:
In an experiment, the group which receives the treatment (in this case injection of actual drug) is known as experimental group because the experiment is being conducted on it. While on the other hand the group which do not receive the treatment is known as control group. The results obtained from the experimental group are compared with the control group to determine the effectiveness of the treatment.
Answer:
A volcano that has erupted in the last 100 years called an "Active Volcano".
Explanation:
A volcano is a mountain that forms when the magma reached the surface to the earth. Magma reaches the surface because it is less dense than the solid rock around it.
An Active volcano erupts on a regular basis or it can erupt at any time and the results were devastated. examples of an Active volcano is mount Katmai in Alaska.
