Answers
The statements is true regarding the movement of substances across cell membrane is that ions are unable to move through the phospholipid bilayer because the nonpolar tail regions of the phospholipids are hydrophobic.
for better understanding let's explain what the statement means
Charged molecules e.g. ions fined it difficult to move or diffuse through a phospholipid bilayer irrespective of size e.g H+ ions is unable to move across a lipid bilayer by free diffusion.from the above we can therefore say that the answer The statements is true regarding the movement of substances across cell membrane is that ions are unable to move through the phospholipid bilayer because the nonpolar tail regions of the phospholipids are hydrophobic is correct

Answer:cell.
[Note: This topic focuses on the cell as a system itself (single-celled organism); as a part of larger systems (multicellular organism), and sometimes as part of a multicellular organism. But they are always as part of an ecosystem.]
1. The living conditions is dependent on the structure, function and interrelatedness of cell parts. A living cell is
composed of a small number of elements - - mainly carbon, hydrogen, nitrogen, oxygen, phosphorous and sulfur.
a. because of its small size and four available bonding electrons, carbon can join to other carbon atoms in chains and rings to form large and complex molecules (macromolecules; organic building blocks / amino
acids)
b. the essential functions of cells involve chemical reactions that involve water and carbohydrates, proteins,
lipids and nucleic acids
c. cell functions are regulated; complex interactions among the different kinds of molecules in the cell cause
distinct cycles of activities - - such as growth and division
d. most cells function within a narrow range of temperature and pH; at very low temperatures, reactions are
slow ; high temperatures and/or extremes of pH can irreversibly change the structure of most protein molecules; even small changes in pH can alter how molecules interact.
e. examples of homeostasis at the cellular level to maintain equilibrium are diffusion, osmosis, and active transport
f. cellular organelles include cytoskeleton, Golgi complex, and endoplasmic reticulum
g. every cell is covered by a membrane that controls what can enter and leave the cell
h. within the cell are specialized parts for the transport of materials, energy transformation, protein building,

As you are walking home from studying at the library late one evening, you get startled by a strange sound behind you. This activates your sympathetic nervous system. What affect does this change have on stroke volume
Answers
Answer:
It has a positive change in stroke volume.
Explanation:
The amount of blood pumped out of the left ventricle of the heart during each systolic cardiac contraction is referred to as stroke volume. During systolic contraction, the heart pumps blood into circulation.
Sympathetic nerves also innervate or stimulate the middle muscular layer of the heart wall. Therefore, an increase of activity in the sympathetic nervous system will trigger an increase in the force of contraction of the heart and, therefore, increase stroke volume. An increase in stroke volume also translates to the pressure of blood being pumped through the arteries.

Explain why you know thatFrom what you learned in the diffusion handbook, what is causing the patient's low arterial oxygen? diuron caused the coral to bleach.
Answers
Answer:
Anemia , ARDS (Acute respiratory distress syndrome) and Asthma.
Explanation:
Anemia , ARDS (Acute respiratory distress syndrome) and Asthma are the causes of low arterial oxygen in patient. this low arterial oxygen is also known as Hypoxemia. in this disease, the level of oxygen decreases in the blood which is causes many problems and disorder in the body of the patient because oxygen is very important for the normal functioning of the body. Diuron causes the coral to bleach by the removal of algae attached to the coral. due to this removal of algae, the whole colour of coral become whitish.
how much time does a cell spend in cytokinesis
Answers
Answer:
Not very long, this process lasts about two seconds because the body needs cells to survive.
Explanation:
Answer:
Cytokinesis performs an essential process to separate the cell in half and ensure that one nucleus ends up in each daughter cell. Cytokinesis starts during the nuclear division phase called anaphase and continues through telophase.(There is no specific time,just until the proccess is complete)
Explanation:
Usually, cells will take between 5 and 6 hours to complete S phase. G2 is shorter, lasting only 3 to 4 hours in most cells. In sum, then, interphase generally takes between 18 and 20 hours. Mitosis, during which the cell makes preparations for and completes cell division only takes about 2 hours.

HELP GIVING BRAINLIEST. List the five building blocks of cells and describe one important life function each one performs.
Answers
Answer:
Explanation:
The Biological Building Blocks are :
Carbohydrates.
One of the primary functions of carbohydrates is to provide your body with energy. Most of the carbohydrates in the foods you eat are digested and broken down into glucose before entering the bloodstream.
Proteins.
They also play a central role in biological processes. For example, proteins catalyse reactions in our bodies, transport molecules such as oxygen, keep us healthy as part of the immune system and transmit messages from cell to cell.
Lipids.
Lipids are essential for all life on Earth. They play many important roles in maintaining the health of an organism. Arguably the most important function lipids perform is as the building blocks of cellular membranes. Other functions include energy storage, insulation, cellular communication and protection.
Nucleic Acids.
Nucleic acids are naturally occurring chemical compounds that serve as the primary information-carrying molecules in cells. They play an especially important role in directing protein synthesis. The two main classes of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).Feb 26, 2020
Combinations.
In most living species, glucose is an important source of energy. During cellular.For example, hemoglobin is a combination of four polypeptide subunits.
plz mark as brainliest
Answer:
Protein, carbohydrates, ATP (Adenosine triphosphate), lipids and nucleic acids
Explanation:
Protein has many roles in your body. It helps repair and build your body's tissues, allows metabolic reactions to take place and coordinates bodily functions. In addition to providing your body with a structural framework, proteins also maintain proper pH and fluid balance
The primary role of carbohydrates is to supply energy to all cells in the body. Many cells prefer glucose as a source of energy versus other compounds like fatty acids. Some cells, such as red blood cells, are only able to produce cellular energy from glucose
ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes
lipids store energy, insulation, cellular communication and protection
nucleic acids have to do with the storage and expression of genetic information

Disscus the importance of phytoplankton to the composition of the earth's atmosphere?
Answers
Answer:
Phytoplankton are essential for atmospheric and climate regulation.
Explanation:
Phytoplankton are autotrophs, they use solar energy, along with inorganic carbon and water to produce their own food source via photosynthesis. During photosynthesis, they also produce oxygen, integral for the planet's atmospheric composition.
At their large biomass, phytoplankton contribute to a majority of the oxygen used by consumers (most animals).
6 CO2 + 6 H2O + light → C6H12O6 + 6 O2
Carbon Dioxide + Water + Light Glucose + Oxygen
Along with fossil fuels, human agricultural practices have contributed large amounts of CO2 to the atmosphere, This causes global warming, a major environmental crisis- global warming also leads to landmass loss, biosphere disruption and reduces biodiversity in mass extinction events.
Phytoplankton carbon cycling produces organic matter which functions as carbon sinks in our oceans. Thus, as phytoplankton use large amounts of CO2, they help combat warming cycles, along with producing O2 in atmospheric and climate regulation.
