The cancer alters there DNA in the tissue thus causing it to get infected. If it does not get treated and it spreads you will die
Explanation:
Answer:
Cancer cells are collected and grown from a living organism. The cancer cells multiply at an inexorable rate. When the cells come into touch, they continue to multiply and develop. A layer of cancer cells forms on top of another. Unlike normal cell division, the number of mitotic divisions in cancer cells is unlimited.

In systemic acquired resistance, which molecule is transported throughout the plant?.
Answer:
Salicylic acid
Explanation:
Salicylic acid is a plant hormone that is essential for a variety of biological parameters, including defence for a plant. There have been many advances in SA-mediated biosynthesis, transport, perception, and signaling over the past two decades. These data show that AS is crucial in local and systemic defensive responses. One such SA-dependent response is systemic acquired resistance (SAR). is a long-distance communication system that provides broad spectrum and long-term resistance to secondary infections throughout the plant. Because of this distinctive property, SAR is a highly sought after trait in agricultural production.This article describes recent developments of the SA function in SAR and analyzes how it connects to other SAR inductors.

Pleurocentesis is the surgical puncture of the membrane lining the chest cavity. true or false
Pleurocentesis is the surgical puncture of the membrane that lines the chest cavity. is a true statement.
What is puncture?Puncture is the removal of any fluid or mass from the human body for laboratory analysis.
What is the pleura What is its function?The pleura serves to keep the lungs “armed” in ventilation, that is, open for gas exchange. This is because the pleural fluid, together with a negative pressure in the pleural cavity, keeps the parietal and visceral pleura stabilized and adherent, preventing lung collapse.
With this information, we can conclude that pleurocentesis is the surgical puncture of the membrane that lines the chest cavity. is a true statement.

Compose a three to four-sentence paragraph that contrasts the organelles and structures you might observe in the cell of a celery stalk and the skin cell of a human
Answer:
Celery Stalk would be made of Cellulose, as it has a Rigid Cell Wall. This gives it it's chewy and hard texture. Plants as a whole also contain Chloroplasts and a Vacuole which Animal Cells do not. The Chloroplasts contain Chlorophyll which job is to absorb Light Energy and carry out Photosynthesis. The Vacuole stores Cell Sap which holds the salts and sugars needed for the Plant. A Skin Cell will not contain these three Organelles, but will contain a Nucleus, Cytoplasm, Mitochondria, Ribosomes, Cell Membrane as do Plant Cells. Below shows the function of these Organelles that both Plant and Animal Cells contain:
Nucleus - Holds DNA for Cell and controlles the Cells Activities
Cytoplasm - Where most Chemical Reactions take place
Mitochondria - To carry out Aerobic Respiration to store Energy for the cell
Ribosomes - To carry out Protein Synthesis
Cell Membrane - To control what substances enter or leave the cell
Explanation:
This is probably way more information than you needed, however hopefully you get the idea! I do tend to 'waffle' a bit so apologies XD!
The contrasting cellular landscapes of a celery stalk and a human skin cell reveal a striking divergence in structural complexity and function. The celery stalk's cells boast a straightforward architecture, characterized by a central vacuole responsible for maintaining turgidity and storing nutrients, while chloroplasts play a pivotal role in photosynthesis.
In stark contrast, human skin cells exhibit a multifaceted arrangement, comprising a nucleus that governs genetic information, mitochondria driving energy production, and an intricate network of keratin filaments providing structural integrity. These distinct cellular compositions highlight the diverse adaptations that cells have developed to fulfill specific physiological requirements in both plant and animal organisms.

How is the evaporation of water in the water cycle similar to the boiling water on the stove?
Answer:
When a pot of water is placed on the burner and brought to a boil, the water evaporates more quickly. Some of the water in the seas and freshwater bodies, such as lakes and rivers, gets warmed by the sun and evaporates during the water cycle.
Explanation:
The evaporation of water is similar to the water cycle similar to the boiling water on the stove as in both processes, heat or increasing temperature causes water to turn into vapor.
What is the water cycle?The water cycle is a cycle or movement of water from Earth to the atmosphere and from the atmosphere to the earth. This process revolves water, and it is a very important process and dependent on temperature.
Watercycle shows different forms of water the water from rivers and ponds evaporates and goes into the atmosphere when the temperature increases and this water when condensation happens releases into the earth in the form of rain.
Therefore, the water cycle and the process of evaporation are comparable because they both involve heat or an increase in temperature making water into vapor.
