Answer:Sclerenchyma
Explanation:Sclerenchyma is thick walled dead lignified cells, they are hard and elastic. The sclerenchyma cells are divided into two groups namely fibers and sclereids. Sclerenchymatous fibers are branched/unbranched, long, hard, pointed cells with tapering ends, thick walls, and narrow lumen.
Answer:
Sclerenchyma is Greek word where "Sclero-" means hard and "enchyma" means infusion. This tissue consists of thick-walled, dead cells and protoplasm is negligible. These cells have hard and extremely thick secondary walls due to uniform distribution and high secretion of lignin and have a function of providing mechanical support

1 poin Students are discussing what they know about cellular transport. Their explanations are displayed in the table. Which student(s) gave an accurate statement regarding cellular transport? * EXPLANATION Passive transport is the movement of molecules from high to low concentration. 2 The sodium-potassium pump is an example of active transport because it uses energy 3 Molecules move against the concentration gradient in passive transport. 4 Diffusion and osmosis are both examples of passive transport. O Student 1 only O Students 1 and 2 Students 1, 2, and 4 O Students 2, 3, and 4
Answer:
Students 1, 2 and 4
Explanation:
Passive transport goes from the higher concentration to the lower concentration in favor of the concentration. Student 3 referred to this as active transport and that is not right.
Simple passive diffusion, facilitated diffusion (via channels and carriers), and active transport are the fundamental forms of membrane transport. A bilayer membrane requires energy to flow through, even with simple passive diffusion. Thus, option C is correct.
What are the cellular transport mechanism in cell?The molecules will migrate from a lower concentration to a greater concentration during active transport.
Energy in the form of ATP is needed for this cellular transport molecule to function. Based on their purpose, the active cellular transporters are divided into four categories.
The sodium-potassium pump in the human body serves as a practical illustration of active transport. Here, potassium ions remain inside the cell while sodium ions are outside the cell.
Therefore, Exocytosis, endocytosis, antiport pumping, and symport pumping are the different types of active transporters.

Compare and contrast the Mann Gulch tragedy and the Storm King tragedy. What are the similarities. What are the differences?
Answer:
hmmm is this question of bio

i dont think so
Answer:
The main difference between Shakespearean comedies and tragedies is the tone used to narrate the events and whether the endings are happy or sad. The comedies have a much lighter and sometimes even romantic tone. The tragedies are filled with despair and regret. Furthermore, the comedies create a jovial mood while the tragedies create a bitter mood among the audience. However, Shakespeare's comedies and tragedies have similar themes. For example, the themes of Romeo and Juliet and A Midsummer Night’s Dream are both forbidden love.

Explanation:
The graph illustrates the activity level of three common digestive enzymes, across a range of pH values. Hydrochloric acid is used by the stomach to aid in digestion and causes the stomach to have an average pH of 1.5 to 3.5. Which enzyme is likely to be active in the acidic environment of the stomach?
Answer:
Digestion starts with the sight, thought, or smell of food. When the brain anticipates an incoming meal, the vagus nerve sends a message to the stomach causing the release of acetylcholine. The binding of acetylcholine to G cells in the stomach starts the secretion of gastrin and, in combination with acetylcholine and histamine, stimulates parietal cells in the gastric glands of the stomach body to start secreting hydrochloric acid (HCl).

In which of the following cell structures are the Drosophila chromosomes
(DNA) located?
A. Lysosomes
B. Nucleus
C. Ribosomes
D. Vacuole
Answer:
DNA is found in the nucleus. So B.
Explanation:
DNA is found in chromosomes and chromosomes are found in the nucleus because the nucleus is basically the DNA of a cell.
In the nucleus, cell structures are the Drosophila chromosomes (DNA) located. The correct option is B.
What is chromosomes?The thread-like components known as chromosomes are found in the nucleus of both animal and plant cells. Protein and a single molecule of deoxyribonucleic acid make up each chromosome (DNA).
DNA is passed down from parents to children and contains the precise instructions that give each kind of living thing its individuality.
a component that can be found in a cell's nucleus. Proteins and DNA are arranged into genes on a chromosome. There are typically 23 pairs of chromosomes in each cell.
One chromosome is made up of one protein and one DNA molecule. Different chromosome sizes can be packed together into a nucleus thanks to proteins called histones.
The DNA for the Drosophila chromosomes is found in the cell's nucleus.
Thus, the correct option is B.

Answer for brainiest :)
Answer:
D
Explanation:
Well, animal cells use simple sugars, like glucose. The simple sugars are the only ones small enough to pass through cell walls. We use ATP to access the energy in the sugars. Cells can either use a aerobic system (using oxygen) or an anaerobic system to metabolize sugars. Humans generally use the aerobic system although in some cases our cells are forced to use the anaerobic system.
