Answer: C. Stream elevation
Stream velocity is the speed of water in a stream. It can be measured in meters per second or feet per second. Stream velocity is highest in the mid stream and lowest along the bottom of the stream. Stream discharge depicts the flow of water from it's source of origin. Stream gradient indicates difference in pressure levels between different water layers. Channel size is the width of water surface acquired by the water body. Stream elevation is the rise in the superficial layer of water. Stream discharge, stream gradient and channel size all influence the stream velocity as they are related to the flow of water. Stream elevation does not influence flow of water hence, does not influence stream velocity.
Answer:
answer is definitely stream elevation

During digestion, water is both added and removed. Which area of the digestive system removes water?
Answer:
Large intestine
Explanation:
Large intestine is the part of the digestive system that consists of cecum, the colon and the rectum. The undigested food enter from small intestine into large intestine. Function of large intestine is to absorb water, salts and vitamins from the undigested food. The undigested and unabsorbed substances form faeces and is stored in rectum till defaecation.
Answer:
Large Intestine
Explanation:
Water from the undigested food is removed by the large intestine. All the nutrients have been absorbed from the food before it reaches large intestine.
Large intestine removes water and make stool consistent enough so that it is easily removed.
There are three main parts of large intestine
a) Cecum - cecum has no major role in food digestion. It passes the food to the colon
b) Colon - It has three sub parts
i. the ascending colon - Bacteria in colon digest the remaining food
ii. the transverse colon - It absorbs fluid and salts
iii. the descending colon - hold the waste

Briefly describe what happens during the light dependent reactions of photosynthesis
Light energy is converted into chemical energy by light-dependent reactions. The goal of photosynthesis's light-dependent reactions is to collect energy from the sun and break down water molecules to produce ATP and NADPH. These two energy-storing molecules are then put to use in light-independent reactions.
What is photosynthesis ?Photosynthesis is a process that plants and other organisms used to convert light energy into chemical energy that can then be released to fuel the organism's activities via cellular respiration.
The light-dependent reaction is a photochemical reaction that occurs in chloroplast thylakoid membranes and converts light energy into adenosine triphosphate (ATP) and nicotinamide adenine dinucleotide phosphate(NADPH).
The photosynthesis process is divided into two stages: light-dependent reactions and the Calvin cycle. Chlorophyll absorbs energy from sunlight and converts it into chemical energy via the light-dependent reactions that occur at the thylakoid membrane.
Thus, The goal of photosynthesis's light-dependent reactions is to collect energy from the sun and break down water molecules to produce ATP and NADPH.

Sometimes, in response to irritants, mucous cells secrete excess mucus. What symptoms might this produce if it occurred in the (a) digestive tract or (b) respiratory passageway? What is the purpose of the mucus production in this situation. Give an example to help support your answer.
Excess mucus production in the digestive tract can cause nausea and abdominal discomfort, while in the respiratory passageway it may lead to coughing and a runny nose. Mucus serves to protect the body, trapping pathogens and foreign particles. A typical example of this protective mechanism in action is the increased mucus seen during a common cold.
Explanation:When mucous cells secrete excess mucus in response to irritants, it can lead to different symptoms depending on the location within the body. If this occurs in the (a) digestive tract, symptoms might include nausea, vomiting, abdominal pain, and diarrhea as the body attempts to expel the irritant. If it occurs in the (b) respiratory passageway, symptoms can include coughing, sneezing, a runny nose, and difficulty breathing due to the obstruction the excess mucus creates.
The purpose of mucus production in this situation is to protect the body by trapping pathogens and other foreign particles. For instance, in the respiratory tract, the mucociliary escalator sweeps mucus and trapped pathogens upward towards the throat to be swallowed or expectorated. Similarly, in the gastrointestinal tract, mucus serves as a lubricant and also contains antimicrobial agents that help protect the lining from irritation and infection.
An example that supports the protective role of mucus production is the common cold. During a cold, the body produces more mucus in the respiratory tract to trap and remove the cold virus. This results in the typical symptoms of a stuffed-up nose and the need to clear one's throat frequently.

Final answer:
The mucous membranes line the lumenal surfaces of several body tracts, with mucus secreted by exocrine glands providing protective and antimicrobial functions.
Explanation:
The membrane that lines the lumenal surfaces of the digestive, respiratory, urinary, and reproductive tracts consists of mucous membranes. These membranes are an assembly of connective and epithelial tissues known as mucosae. They are essential for protecting the internal layers of these tracts and serve as a barrier against the external environment. The mucous membranes are coated with mucus, which is secreted by exocrine glands within the epithelial tissue. This mucus is not only a lubricant but also serves to trap debris, particulate matter, and microbes, providing an additional antimicrobial barrier. The underlying connective tissue layer, called the lamina propria, provides support for the epithelial layer, allowing it to maintain its integrity against physical and biological stresses.

Not breastfeeding baby what happens later
Final answer:
Not breastfeeding a baby means missing out on the vital nutrients, immunoglobulins, and other health benefits provided by breast milk. Sudden cessation of breastfeeding can cause physical effects in the mother, like breast engorgement and leakage, due to a disrupted supply-demand relationship. Without resumption, milk production will usually cease within about a week.
Explanation:
When a baby is not breastfed, they do not receive the benefits provided by breast milk. Suckling stimulates the production of prolactin which leads to milk production in the mammary glands. Oxytocin is released as well, which aids in milk let-down. This process ensures that the baby receives a balanced supply of nutrients tailored to its development phase, including colostrum, which is rich in immunoglobulins necessary for the infant's immune system. Additionally, breast milk contains components that help the infant's digestive system expel meconium and clear bilirubin. If a mother stops breastfeeding suddenly, prolactin and oxytocin levels can decrease, leading to breast engorgement and leakage, mirroring the experiences in the initial weeks following birth. The engorgement occurs because the supply-demand relationship has been disrupted. Although a lactating person can produce milk for years, if breastfeeding is not resumed within approximately one week, the remaining milk will be reabsorbed, and in most cases, no more will be produced.

Compulsive exercise would most likely be present in which eating disorder?
The correct answer is Anorexia Nervosa.
Compulsive exercise is a common feature in individuals with Anorexia Nervosa. This behavior is often driven by an intense fear of gaining weight or becoming fat, and it is used as a means to control body shape and weight. People with Anorexia Nervosa may engage in excessive physical activity despite being underweight, injured, or in poor physical health. This compulsive exercise can exacerbate the health risks associated with the disorder, including cardiac complications, osteoporosis, and muscle wasting.
While compulsive exercise can also be present in other eating disorders such as Bulimia Nervosa or Eating Disorder Not Otherwise Specified (EDNOS), it is most characteristic of Anorexia Nervosa due to the relentless pursuit of thinness and the restrictive eating patterns associated with the disorder. It is important to note that not all individuals with Anorexia Nervosa will exhibit compulsive exercise, but it is a common and concerning symptom when present.
