Answer:
Cellular respiration takes place in the cells of fungi, animals, and plants.
Explanation:
Notice how these things are all living things. Cellular respiration is the process of turning glucose into ATP. This ATP is used for cellular functions and also to break down more glucose for more ATP. It is kind of like a circular process.

Which structure allows
gases and nutrients in
and out of the cell?
A. mitochondria
B. cytoplasm
C. nucleus
D. cell membrane
The cell membrane allows gases and nutrients in and out of the cell.
The correct answer is option D, the cell membrane. The cell membrane, also known as the plasma membrane, is a vital component of all cells. It serves as a selectively permeable barrier that separates the internal environment of the cell from its external surroundings. One of its crucial functions is to regulate the movement of substances in and out of the cell, including gases and nutrients.
The cell membrane is made up of a phospholipid bilayer embedded with various proteins. These proteins play a role in facilitating the transport of molecules across the membrane. There are two main types of transport across the cell membrane:
Passive Transport: This includes processes like diffusion and facilitated diffusion, where substances move from an area of higher concentration to an area of lower concentration. Small gases like oxygen and carbon dioxide can passively diffuse through the lipid bilayer of the membrane.
Active Transport: This involves the use of energy to move substances against their concentration gradient, from an area of lower concentration to an area of higher concentration. Nutrients and other molecules can be actively transported using protein pumps.
In both cases, the cell membrane is responsible for controlling what enters and exits the cell, maintaining an appropriate internal environment for cellular functions. This selective permeability ensures that essential gases like oxygen and nutrients can enter the cell while waste products can exit. Thus, the cell membrane is a crucial structure that enables the exchange of gases and nutrients required for cellular metabolism and survival.

Explanation:
Explain what is probably going wrong in the following scenario.
Situation: Using a range of different fertilization techniques and products, a gardener has been working to improve fertility on a stretch of lawn that had very poor, sandy soil. The gardener has added a range of soil amendments, including additions of clay, compost, peat moss, and NPK fertilizers. For a period of time the gardener seemed to succeed, and he increased his treatments. Recently, though, discolored vegetation that seems almost drought-stricken has been appearing in the grass. The gardener is now wondering what has gone wrong.

What is mars' origin of the name?
Answer:
Mars was named by the ancient Romans for their god of war because its reddish color was reminiscent of blood
Explanation:
A researcher sequences the genome of a variety of bacterial and eukaryotic cells. She finds that the bacterial genome is smaller, but that there are more genes for a given number of base pairs in the eukaryotic cells. In other words, there are fewer genes per unit of length of DNA in the eukaryotic cells. What do you predict she will find if she examines the DNA more closely
From this observation, it is possible to conclude that there are more repetitive sequences in the eukaryotic DNA than in the bacterial DNA. Prokaryotic genes do not contain introns.
Introns are internal non-coding segments of eukaryotic genes that must be removed to produce the final mature mRNA.
In prokaryotic genomes, there are no introns, and genes are expressed in groups known as operons.
Eukaryotic genomes contain highly repetitive intergenic (regulatory) and intragenic (introns) non-coding regions.

elect the correct statement regarding the lungs. Select one: a. The left lung is larger than the right lung. b. Only the right lung has a hilum. c. The left lung contains three lobes while the right lung contains two lobes. d. The left lung has more bronchopulmonary segments than the right lung. e. The left lung contains two lobes while the right lung contains three lobes.
Answer:
The right lung is smaller than the right to make room for the heart.
Explanation:
so the answer is A :)
The left lung contains two lobes while the right lung contains three lobes. Therefore option E is correct.
The statement that the left lung contains two lobes while the right lung contains three lobes is correct.
The right lung is divided into three lobes: the upper lobe, middle lobe, and lower lobe. On the other hand, the left lung is divided into two lobes: the upper lobe and lower lobe.
This anatomical difference is due to the position of the heart, which is located more towards the left side of the chest. The presence of an additional lobe in the right lung allows for a better fit around the heart.
Understanding the lobes of the lungs is important in assessing and diagnosing respiratory conditions and in surgical procedures that involve lung resection or transplantation.
Therefore option E The left lung contains two lobes while the right lung contains three lobes is correct.

Which of the following statements regarding digestion and absorption of carbohydrates is TRUE? Lactose intolerance results from an insufficiency of the enzyme amylase. Digestible polysaccharides are broken down into the monosaccharides glucose, galactose, and fructose, which can be absorbed. Sucrose is the main form of carbohydrate that can be absorbed by active transport across the intestinal epithelium. Carbohydrate digestion begins in the stomach. Cellulose from plants is a polymer of glucose that can be easily digested and absorbed by the human GI tract.
Answer:
CARBOHYDRATE DIGESTION AND ABSORPTION
For dietary carbohydrates to be utilized by the body, they must be converted during digestion to monosaccharides. In addition to starch, the other major dietary carbohydrates are the disaccharides lactose and sucrose, and the monosaccharide fructose. The monosaccharides produced by complete digestion of these dietary carbohydrates are glucose, galactose, and fructose.
The digestive process begins with salivary amylase, which randomly cleaves the α-1,4 linkages of starch. Although amylase digestion begins in the saliva, pancreatic α-amylase is more important to the complete digestion of starch (Fig. 19-1). Starch is degraded first to dextrins and then to a mixture of glucose, maltose, and isomaltose (containing the α-1,6 linkages that are not digested by amylase).
The major disaccharidases, located in the brush border of the intestinal lumen, are
•
Maltase—hydrolyzes maltose
•
Sucrase-isomaltase—hydrolyzes sucrose and isomaltose
•
Lactase—hydrolyzes lactose
Whenever lactose goes undigested, it is not absorbed and passes into the large intestine. Here lactose is acted on by the intestinal flora that ferment it, producing large quantities of CO2, hydrogen gas, methane, and organic acids; the last irritate the intestines, increasing intestinal motility. All these products have only one way out. Thus, the symptoms that characterize lactose intolerance are bloating and flatulence and, in extreme cases, a frothy diarrhea. Lactose intolerance is least common in Northern Europeans and their descendants and most common in descendants of Asian, African, and South American origin.
HISTOLOGY
Brush Border Dynamics
The unstirred brush border of the intestinal lumen consists of finger-like processes, known as microvilli, of the surface absorptive cells. Many enzymes associated with the process of digestion and absorption are located on the surface of these microvilli. This allows the products of digestion such as free fatty acids, amino acids, and monoglycerides to be absorbed by the cells rather than be swept into the lumen itself.
Why can’t a virus reproduce on its own?
Answer:
Viruses can only replicate themselves by infecting a host cell and therefore cannot reproduce on their own.At the most basic level, viruses consist of genetic material contained within a protective protein coat called a capsid; the existence of both genetic material and protein distinguishes them from other virus-like particles such as prions and viroids.They infect a wide variety of organisms: both eukaryotes (animals, fungi and plants) and prokaryotes (bacteria).A virus that infects bacteria is known as a bacteriophage, often shortened to phage.The study of viruses is known as virology, and those who study viruses are known as virologists.It has been argued extensively whether viruses are living organisms.Most virologists consider them non-living, as they do not meet all the criteria of the generally accepted definition of life.They are similar to obligate intracellular parasites as they lack the means for self-reproduction outside a host cell, but unlike parasites, viruses are generally not considered to be true living organisms.A primary reason is that viruses do not possess a cell membrane or metabolise on their own - characteristics of all living organisms.Examples of common human diseases caused by viruses include the common cold, the flu, chickenpox and cold sores.Which of the following models shows the flow of energy in a woodland ecosystem?

Human embryonic development is the development and formation of the human embryo. It is characterized by the process of cell division and cellular differentiation of the embryo that occurs during the early stages of development. In biological terms, the development of the human body entails growth from a one-celled zygote to an adult human being. Choose ALL of the statements that correctly describe stages in human embryology and gestation.
The normal period of gestation is about 40 weeks.
The germinal stage refers to the time from fertilization through the development of the early embryo until implantation is completed in the uterus in about 21 days.
The stages of human development include, in order: zygote, blastocyst, embryo, and fetus
A blastocyst, if untouched and allowed to remain implanted, will eventually develop into a morula.
Changes to the form of the embryo come from differentiation and growth.
The statements that correctly describe gestation are: the normal period of gestation is about 40 weeks; the stages of this process include: zygote, blastocyst, embryo, and fetus; and changes to the form of the embryo come from differentiation and growth.
The gestation period in humans lasts about 40 weeks and comprises different stages and processes from conception until birth. The main stages of this process include:
Zygote: Fertilized ovum.Blastocyst: Cluster of cells that is the result of the zygote going through cell division.Embryo: Unborn human that is still developing, usually before the 8th week of gestation.Fetus: Unborn human in development after the 8th week of gestation.Moreover, this process implies differentiation as cells specialize for specific functions, for example, muscle cells or nerve cells, and growth as the number of cells increases and therefore the embryo or fetus increases in size.
