Please answer tysm!!!
Answer:
The plant would wilt with low turgor pressure.
Explanation:
Turgor is what makes living plant tissue rigid. Loss of turgor, resulting from the loss of water from plant cells, causes flowers and leaves to wilt :3

The Amazing World Inside a Human Cell
By Alisa Machalek and Emily Carlson
Posted June 29, 2011
Let's take a quick trip inside to see how cells carry out their major tasks.
Imagine you've shrunk down to 3 millionths of your normal size and are now about 0.5 micrometers tall—way
smaller than a dust mite or the width of a hair strand. At this scale, a medium-sized human cell looks as big as
a football field.
Nucleus
From your new perspective, the cell's somewhat spherical nucleus catches your
attention. It looks about 50 feet wide. Occupying up to 10 percent of the cell's
interior, the nucleus is the most prominent organelle, or cellular compartment. It
contains the cell's genetic material, DNA, which guides the making of billions of
protein molecules that participate in nearly every cellular process.
Membranes
The double membrane that bounds the nucleus flows into the ribosome-studded rough endoplasmic reticulum
(purple). Proteins are processed and lipids are manufactured in the smooth endoplasmic reticulum (blue) and
Golgi apparatus (green). Credit: Judith Stoffer, jStoffer Medical Illustration.
Encasing the cell is a membrane with special gates, channels and pumps that let in or
force out selected molecules. The membrane protects the cell's internal
environment—a thick brew called the cytosol made of salts, nutrients and proteins

Cell Structure and Functions Activity Worksheet
Instructions: Read the article The Amazing World Inside a Human Cell, and then answer the following questions.
Background Information
Read the introductory paragraphs, and answer the following questions in your own words. Use complete sentences, and provide textual evidence to support your answers.
How many cells does the human body have, and how many different types are there?
What does the author want readers to imagine as they begin reading? Why?
Text-dependent Questions
Use quotes from the text or summarize the text in your own words to answer the following questions or prompts. Use complete sentences, and provide textual evidence to support your answers. Note: The first one has been completed for you.
What material does the nucleus contain? What is the purpose of this material?
The nucleus contains "the cell's genetic material, DNA." DNA makes protein molecules to help with almost every cellular process.
Using evidence from the text, describe the purpose of the cell membrane.
How do the two types of endoplasmic reticulum differ?
Using evidence from the text, describe the purpose of the Golgi complex.
Based on this excerpt, summarize the job of mitochondria.
Excerpt: "About the size of pickup trucks from where you're floating, the organelles called mitochondria convert energy from your food into adenosine triphosphate, or ATP, to power biochemical reactions. A typical cell burns through 1 billion molecules of ATP every 1 to 2 minutes."
Fact vs. Opinion
Read each statement and decide if it is a fact (can be proven with evidence) or an opinion (personal belief).
Different cell types also have special duties, like building skin or bone, pumping out hormones, or making antibodies.
Animal cells are more interesting than plant cells.
Proteins are processed and lipids are manufactured in the smooth endoplasmic reticulum and Golgi apparatus.
Structure and Purpose
Use the text and visuals to answer the following questions. Use complete sentences, and provide textual evidence to support your answers.
How do the authors structure (arrange) the article?
What is the purpose of the subheadings?
What is the purpose of the images and captions in the article?
What is the purpose of the article?
How does the final paragraph relate to the main idea of the article?

Oxygen is increased by the movement of water.
Oxygen is decreased by the movement of water.
Nutrients are increased by the movement of water.
Nutrients are decreased by the movement of water.
what happens to molecules that are not absorbed in the small intestine?
Answer:
Hold up it is long
Explanation:
Instead, its purpose is to complete water and electrolyte (minerals found naturally in the body, such as potassium, calcium, sodium, and magnesium) absorption begun by the small intestine. Those components of food that are not needed or cannot be absorbed are excreted from the colon in stool.
When Those components of food that are not needed or cannot be absorbed are excreted from the colon in the stool.
What is Small Intestine?
The small intestine is divided into three components: Jejunum; Duodenum; Ileum; Positions of the Small Intestine Complete Digestion of Food.
When The partly digested food is absorbed by the duodenum of the small intestine along with the digestive juices from the pancreas, liver, and its walls.
Although, Instead, it intends to complete water and electrolyte (minerals found inherently in the body, such as potassium, calcium, sodium, and magnesium) absorption formed by the small intestine.
Therefore, Those components of food that are not needed or cannot be absorbed are excreted from the colon in the stool.

Which student correctly identified the geological process that formed Himilayan mountains?
Answer:
Student 2 is correct!
Explanation:
The Himalayas, which stretch over 2400 km between the Namcha Barwa syntaxis in Tibet and the Nanga Parbat syntaxis in Kashmir, are the result of an ongoing orogeny — the result of a collision of the continental crust of two tectonic plates. This immense mountain range was formed by tectonic forces and sculpted by weathering and erosion.
The geological events include the formation of the mountains. Student 2, stated about the collision of the continental plates. Thus, option A is correct.
What are continental plates?Continental plates are the plate tectonics that is found between the crust and the mantle of the earth (lithosphere). The continental plates are said to have less density than the oceanic plates. This results in the formation of the elevation unlike the depression in oceans.
The converging of the continental plates resulting from collision causes the crust to uplift and form the Himalayan mountains. The tectonic plate of the continents melts, slides, and falls against each other to form the elevated structure.
Therefore, option A. student 2 correctly explained the Himalayan mountain formation.

Please help me answer this question!!
Your liver is a vital organ that is responsible for breaking down toxins in your body, among other things. Your liver cells have a large amount of which organelle? Choose from the following.
A. Nucleus
B. Cell membrane
C. Cell wall
D. DNA/Genetic material
E. Ribosome
F. Lysosome
G. Chloroplast
Answer:
F. Lysosome
Explanation:
Lysosomes ,also called the 'Waste Disposals Of A Cell', are sac-like organelles that contain powerful digestive juices in them. They help in digesting worn out cells or foreign particles such as Toxins or Waste, that don't belong there. Their enzymes are so powerful that, when they burst [During a spontaneous change in cell metabolism], they digest the whole cell with them.

what are the structures in the leaves that are unutilized in transpiration? ( pls hurry)
Answer:
Stomata – Stomata are pores in the leaf that allow gas exchange where water vapor leaves the plant and carbon dioxide enters. Special cells called guard cells control each pore's opening or closing. When stomata are open, transpiration rates increase; when they are closed, transpiration rates decrease.
