Which of the following is not true about the esophagus?
a. it is made up principally of longitudinal and circular smooth muscle
b. it extends from the pharynx to the stomach
c. it is responsible for water absorption
d. its mucosa contains mucus-producing cells
Answers
The statement that is not true about the esophagus is "it is responsible for water absorption. "The esophagus is a muscular tube that links the pharynx and stomach. The esophagus is about 25 centimeters (10 inches) long and is located between the lower end of the pharynx and the uppermost portion of the stomach.
The food bolus is propelled down the esophagus toward the stomach by involuntary contractions of the muscular wall known as peristalsis. The smooth muscle layers of the esophagus are found in both the circular and longitudinal planes. They are situated outside of the mucosa and submucosa layers. The submucosa layer includes the esophageal glands. The mucus membrane that lines the esophagus is stratified squamous epithelium.The mucosa layer of the esophagus contains mucus-producing cells. They secrete mucus to protect the esophageal lining against any damage from swallowed substances.
The esophagus is not responsible for water absorption. Instead, it moves food into the stomach by contracting in a rhythmic pattern to move the food bolus down the digestive tract. Therefore, the statement that is not true about the esophagus is "it is responsible for water absorption."

All cells can synthesis ATP by way of glycolysis. Many cells have to metabolize pyruvate without oxygen by doing...?
Answers
Answer:
Anaerobic respiration
Explanation:
As rightly stated in this question, cells of all living organism synthesize ATP via the process of cellular respiration. Cellular respiration, however, occurs in stages starting with GLYCOLYSIS, which breaks down glucose to form PYRUVATE.
The metabolism of pyruvate in subsequent steps depends on whether the respiration process is occuring with or without oxygen. Without oxygen, pyruvate is metabolized in a process called ANAEROBIC RESPIRATION. Anaerobic respiration employs other molecules asides OXYGEN for last electron acceptor.

stringent method of decontamination that we use in the microbiology lab? Which is more the most A) hand washing B) 70% ethanol C) [0% bleach D) autoclaving
Answers
The most stringent method of decontamination used in the microbiology lab is D) autoclaving.
Autoclaving is a process that uses high pressure and steam to kill all forms of bacteria, viruses, and other microorganisms. It is the most effective method of decontamination and is used for sterilizing laboratory equipment, surgical instruments, and other materials that may come into contact with pathogens.
While hand washing, 70% ethanol, and 10% bleach are all effective methods of decontamination, they are not as thorough or reliable as autoclaving. Hand washing may not remove all microorganisms, and the effectiveness of ethanol and bleach can be affected by factors such as the presence of organic material or the length of contact time.
Therefore, autoclaving is the most stringent method of decontamination used in the microbiology lab.

scientist isolate cells in various phases of the cell cycle what is the most likely part of the cell cycle
Answers
Scientists isolate cells at various stages of the cell cycle, with the most common stage occurring between the G1 and S phases.
However, because mitosis and cytokinesis last only about an hour each, interphase—the time between mitoses—takes up approximately 95% of the cell cycle. The nucleus appears uniformly shaped because the chromosomes are dispersed throughout the nucleus during interphase and decondensed.
The cell grows in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage) during the four stages of the cell cycle. The Interphase is made up of the stages G1, S, and G2, which is the time between cell divisions.

Where do mammals and birds get the energy for this heat?answer choiceso from oxygen they breath ino from sunlight the animals absorbo from body fat that keeps all heat trapped in the bodyo from food the animals eat
Answers
Reptiles do not generate their own heat and rely on basking in the sun in order to warm up.
Mammals and birds, however, have the ability to create their own heat. The energy to generate this heat comes from food they eat. Mammals and birds obtain energy from the breakdown of carbohydrates, proteins, and fats in the food they consume. This energy is then used by the body to create heat through metabolic processes such as respiration and digestion. This process helps to maintain the body temperature of these animals, even in cold environments. Heat can also be generated by burning stored body fat which helps to keep the body warm in colder environments. So, the energy that mammals and birds use to generate their own heat comes from the food they eat and the stored body fat.

Photosynthesis and cellularrespiration
Answers
Answer:
Both are processes within the cell which make chemical energy available for life. Photosynthesis transforms light energy into chemical energy stored in glucose, and cellular respiration releases the energy from glucose to build ATP, which does the work of life.
Explanation:
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Glucose is used as food by the plant and oxygen is a by-product. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.

Ecological Succession: The process by which the ecosystem colonization of species from barren land to a complex ecological community.
What is Ecological Succession?The process through which a region's species and habitat mix changes over time is known as ecological succession. These communities gradually take the place of one another until a "climax community"—such as an established forest—is attained or until a disruption, like as a fire, happens. The notion of ecological succession is important to ecology.
A dirt field, for example, is ploughed and left for the summer. Weeds begin to sprout on the field throughout the summer. Small bushes begin to develop once the weeds have grown. Trees begin to sprout in the field after a few years.

Antigen, stabilizers, surfactants, diluents, preservatives
Explanation:
Antigen: This is part of the protein structure virus or part of its genetic material. These parts are active. But sometimes, the inactivated form of the virus is also included in the vaccine. Stabilizers: Avoid other chemical reactions occurring in the interior of the vaccine. Surfactants: They prevent the occurrence of sedimentation and agglutination of the elements inside the vaccine. Diluent: Used to dilute the vaccine in an appropriate concentration before being used. Preservatives: As the word says, preservatives avoid any possible contamination of the vaccine. These elements´ use depends on the doses prepared. If it is only for one-person use, then they are not needed. But if the doses are to be used by more than one person, they need preservatives because once the vaccine is opened it is vulnerable to contamination.Jack and Diane have a child with O- type blood.

Therefore, despite the fact that each of human cells contains roughly 20,000 identical genes, each cell may choose which genes to "turn on" and which to keep "shut off." All of the cells within your body originated from a single cell, as you are undoubtedly already aware. It is apparent that each person has a unique genome.

How does the amount of matter in a single seed compare to the amount of matter in the plant that has grown for five weeks
Answers
There is a huge difference in the amount of biomass present in the seed and that in the plant grown for five weeks.
Biomass is the organic material present inside a living organism, and which can be used for heating, generation of energy or survival of population. Biomass is renewable in nature and is acquired from plants and animals. When the seed is considered, it consists of very small of amount of biomass because seed is in dormant phase and not alive completely. When plant grows for five weeks, it has grown for some time and acquired comparatively greater amount of biomass by taking in more nutrition and water from the soil. Numerous abiotic factors help in increasing the biomass of plant.

Answer:
True
Explanation:
Denaturing is a process in which protein looses its shape. Due to loss of shape (structure), protein also looses its function. This change in shape is due to change in temperature or pH of the protein.
Due to high temperature the shape of active site gets distorted due to which it becomes non functional. Change in active site of enzyme will change shape of the enzyme and make it unfit for the substrate/reaction.
You have a bagged sweet feed that is 10% protein. You need a 14% protein feed to finish your steer, so you will supplement with SBM that is 38% protein. What ratio of feed to supplement should you mix?
Answers
For every 1 part of the sweet feed, we will need to add 0.143 parts of soybean meal to achieve a 14% protein content in the final feed mixture.
What is a protein supplement?A protein supplement is defined as the protein and nutrition sources that are obtained from external sources in the form of powders and tablets used by athletes, bodybuilders etc. to achieve their daily protein intake amounts.To determine the ratio of feed to supplement that you need to mix, you can use the following formula:
(Feed protein content - Desired protein content) / (Supplement protein content -Feed protein content)
In this case, the feed protein content is 10%, the desired protein content is 14%, and the supplement protein content is 38%.
So, putting the values:
(0.14 - 0.1) / (0.38 - 0.1) = 0.04 / 0.28 = 0.143
This means that for every 1 part of the sweet feed, you will need to add 0.143 parts of soybean meal to achieve a 14% protein content in the final feed mixture.

On the other hand, the endocrine system is responsible for maintaining homeostasis and long-term control through the release of hormones. The pituitary gland, often referred to as the "master gland," regulates the function of other endocrine glands and secretes various important hormones. Gonadotropins, such as luteinizing hormone (LH) and follicle-stimulating hormone (FSH), are involved in reproductive functions. Antidiuretic hormone (ADH) helps regulate water balance and blood pressure. Steroids, derived from cholesterol, are a class of hormones that exert various effects. Receptors are proteins found on target cell membranes that bind to specific hormones, initiating cellular responses.Hence, the correctly matched terms from the Endocrine System Chapter are:
