Answer:
Structure of Plasma Membranes
The plasma membrane (also known as the cell membrane or cytoplasmic membrane) is a biological membrane that separates the interior of a cell from its outside environment.
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells. Plasma membranes must be very flexible in order to allow certain cells, such as red blood cells and white blood cells, to change shape as they pass through narrow capillaries.
The plasma membrane also plays a role in anchoring the cytoskeleton to provide shape to the cell, and in attaching to the extracellular matrix and other cells to help group cells together to form tissues. The membrane also maintains the cell potential.
In short, if the cell is represented by a castle, the plasma membrane is the wall that provides structure for the buildings inside the wall, regulates which people leave and enter the castle, and conveys messages to and from neighboring castles. Just as a hole in the wall can be a disaster for the castle, a rupture in the plasma membrane causes the cell to lyse and die.

What is the end product of the light-independent reaction?
Explanation:
Oxygenic photosynthesis is composed of two stages: the light-dependent reactions and the light-independent reactions. The light-independent reactions use the ATP and NADPH from the light-dependent reactions to reduce carbon dioxide and convert the energy to the chemical bond energy in carbohydrates such as glucose.
Select the correct formula for cellular respiration.
A. Glucose + oxygen → carbon dioxide + water + ATP
B. Glucose + water → oxygen + carbon dioxide + ATP
C. Carbon dioxide + glucose → oxygen + water + ATP
D. Carbon dioxide + water + ATP → glucose + oxygen
Answer:
I want to believe it's glucose + oxygen = Carbon dioxide, water, and ATP but please correct me If I end up wrong! ♡
The correct equation for the process of cellular respiration is Glucose + oxygen → carbon dioxide + water + ATP.
WHAT IS CELLULAR RESPIRATION:
Cellular respiration is the process by which living organisms obtain energy (ATP) needed for metabolic activities. It involves the breakdown of sugar molecule (with or without oxygen) to yield energy in form of ATP and the release of carbon dioxide (CO2).The general equation of cellular respiration is as follows:
Glucose + oxygen → carbon dioxide + water + ATP.Learn more at: https://brainly.com/question/18702857

Explanation:
If a starfish sustains damage to a limb, it often grows a new one. If a human adult sustains damage to his or her spinal cord,
mobility is often impaired. If a gecko loses its tail, it may grow a new one. Which type of cell is less likely to go through the
cell cycle after being damaged starfish limb, human spinal cord, or gecko tail? Support your answer
Answer:
The Human spinal cord. The Spinal cord, if fractured or broken, would take a long time to heal and regenerate (if at all, it barely regenerates, leaving it impaired), while the starfish and gecko can just regrow those parts.

write a comparison between the agriculture in bangladesh and vietnam
Answer:
Explanation:
In Vietnam, 34.8 percent of land is dedicated to Agricultural use. In 2018, agriculture, forestry and fishing accounted for 14.68 percent of the country's GDP. Vietnam's main agricultural crops are rice, cassava, maize and sweet potatoes. The relaxation of the state monopoly on rice exports transformed the country into the world's second or third largest rice exporter. Other cash crops produced and exported are coffee, cotton, peanuts, rubber, sugarcane, and tea.
Land dedicated to agricultural use in Bangladesh is 70.1 percent. Agriculture is the largest employment sector in Bangladesh. Most Bangladeshis earn their living from agriculture. Although rice and jute are the primary crops, wheat is assuming greater importance. Tea is grown in the northeast. Because of Bangladesh's fertile soil and normally ample water supply, rice can be grown and harvested three times a year in many areas.
Which part of the digestive canal is involved in: (i) absorption of food ________________. (ii) chewing of food ________________. (iii) killing of bacteria ________________. (iv) complete digestion of food ________________. (v) formation of faeces ________________.
Answer:
Absorption of food is Small intestine.
Chewing of food is Buccal cavity.
Killing of bacteria is Stomach.
Complete digestion of food is Small intestine.
Formation of faeces is large intestine.
Explanation:
Digestion is the process where larger molecules are broken into smaller pieces to release nutrients.
Digestion of food starts from the mouth especially carbohydrates. When it is consumed the buccal cavity is involved in chewing which break it into smaller pieces and the salivary gland release amylase to break it down. It then move to the small intestine where enzymes break food into smaller pieces. The stomach is responsible for killing bacteria because it is an acidic.region. when the food are broken down, the nutrients are then absorbed through small intestine and the undigested food form faeces in the large intestine.
What do scientists theorize about the origins of the Moon? Choose the most recent explanation.
Group of answer choices
Moons like ours are commonplace among the planets and are drawn into orbit by strong gravitation on smaller bodies.
Identical forms of elements on both the Moon and Earth lead scientists to believe that Earth and Moon were formed.

Which best matches a type of genetic material with its description? Nucleotides form a helical structure that is called a gene. Genes combine to form structures called nucleotides. Chromosomes create genes. DNA is located in the nucleus.
Answer:
the correct answer is DNA is located in the nucleus
Explanation:
DNA being located in the nucleus is the best match for a type of genetic
material with its description.
DNA contains the genetic components of organisms and are found in the
nucleus of cells.
Options such as nucleotides forming a helical structure that is called a gene
is false as it actually forms a DNA. Genes doesn't also combine to form
structures called nucleotides.

whats the difference between prokaryotes and eukaryotic cells?
Answer:
Prokaryotes are your bacteria and your single celled organisms. Eukaryotes are your multi celled organisms.
Explanation:
Prokaryotes don't have membrane bound organelles the cell itself serves as a capsule and holds its chromosomal DNA. Your Eukaryote cells are in plants and animals. It has a defined nucleus, membrane bound organelles, but doesn't have cilia like the prokaryote cell does. Cilia helps the prokaryote cell move.
