of a plant during photosynthesis?
Answers
The correct answer is C. It is taken in from the air
Explanation:
Carbon dioxide is a gas that exists mainly in the air or atmosphere. Additionally, this chemical compound is required for plants as part of photosynthesis (process to produce energy). In this process, plants take dioxide from the air through the leaves' stomata, which are small spores, use this along with sunlight and water to produce energy, and later release oxygen. According to this, carbon dioxide is taken from the air by plants (option C) while oxygen is given off.

Which urine characteristics are indicative of acute tubular necrosis (ATN) caused by intrinsic (intrarenal) failure?
A. Urine sodium >30 mEq/L.
B. Urine osmolality >500 mOsm.
C. Fractional excretion of sodium (FENa).
Answers
Answer: A. Urine sodium >30 mEq/L.
Explanation:
Acute tubular necrosis (ATN) is a medical condition that involves the necrosis -death- of the tubular cells that form the renal tubule, which carries urine to the ureters while reabsorbing 99% of water and concentrates the salts and by-products of metabolism for disposal. So it is a kidney disorder that involves damage to cells in the tubules of the kidneys, which can lead to acute kidney failure. Tubules are small tubes in the kidneys that help filter blood as it passes through them. ATN is often caused by a lack of blood flow and oxygen to the kidney tissues (kidney ischemia). It can also occur if kidney cells are damaged by a poison or harmful substance.
ATN occurs with acute renal failure (ARF) and is one of the most common causes of ARF. The presence of "dark brown bodies" of epithelial cells found in the urine during urinalysis is pathognomonic for ATN.
Risks for ATN include:
Low blood pressure (hypotension) lasting more than 30 minutesInjury or trauma resulting in muscle damageRecent major surgeryReaction to blood transfusionSeptic shock (a serious condition that occurs when a whole-body infection leads to dangerously low blood pressure)Since acute tubular necrosis is classified as a kidney cause of acute kidney failure, the diagnosis is made by a sodium excretion fraction greater than 3% and the presence of granular casts formed by Tamm-Horsfall protein with epithelial cell fragments on general urine examination. So, as it eas explained before, it concentrates the salts and by-products of metabolism thereby it is characterizad by urine sodium levels greater than 30 mEq/L.

The expression in milliequivalents of a known ionic concentration by weight is obtained by dividing the number of milligrams per liter by the atomic weight of the ion and multiplying the result by the valency of that ion.
The ability of metabolically active tissue (e.g. muscle) to change energy sources from fat to carbohydrates (and vice versa) is termed
Answers
Answer:
The ability of metabolically active tissue (e.g. muscle) to change energy sources from fat to carbohydrates (and vice versa) is termed: Metabolic flexibility.
Explanation:
The human body primarily uses two sources of energy, glucose and fat. Glucose is found in the bloodstream and stored as glycogen in muscles and the liver, and fat in adipose tissue and in fatty acids. Metabolic flexibility is the ability of the body to alternate between the different energy substrates according to the circumstances of each moment. People with good metabolic flexibility will find it easier to use body fat and perform better physically. At lower intensity during exercise, more fat is consumed and at higher intensity, more glucose. If that high intensity is maintained, glycogen stores will be depleted. So then, how much energy is stored, how much is needed and how it will be delivered, is part of the reading that our body performs. This cellular adaptation to the requirements is known as metabolic flexibility.

4. The elbow is located _________________ to the wrist.
Answers
Elbow is the joint between upper and lower arm while wrist is the joint between lower arm and hands.
So below :P
The elbow is located proximal to the wrist.
What is an elbow?The humerus, ulna, and radius are the three bones that make up the elbow, which is a hin-ged joint. The cartilage on the extremities of the bones protects them.
Because cartilage has a springy texture, joints can move smoothly against one another and can absorb trauma. Ligaments that make up the joint capsule hold the bones together.
The wrist is close to the elbow. This is so because the wrist makes the site of attachment more distant, while the elbow brings it closer.
The elbow joint is proximal to the wrist and distal to the shoulder because the humerus is longer than the radius and ulna combined. The elbow joint serves as the focal point or center in this situation.
Therefore, the elbow is located proximal to the wrist.

Primate communication can be compared to human communication in that:________.
a. primate communication is very simple and across all the species consists of only a handful of "meaningful" sounds; this is entirely different from human language.
b. although some primates have the ability to transmit meaning from one individual to another, this always happens within a species, never between species; this is similar to humans, since humans do not really understand other animals either.
c. many primates make sounds that seem to be labels for things, like specific food items or specific predators, but primate communication lacks nuance or complexity of any kind; this is unlike human language.
d. for at least some Old World monkeys and apes, communication seems to be very context dependent, and specific sounds can have different meanings by making small changes; this is like human language.

Although some primates have the ability to convey meaning from one individual to another, this always occurs within a species, never between species; this is similar to humans in that humans don't really understand other animals either.

This particular drug requires her to make a mixture of L-histidine, polysorbate 80, and sucrose that must heated and swirled to mix. Which of the following types of glassware will she used for making this mixture? Justify your answer.
Answers
Answer:
This question lacks options, the options are:
A) 100 ml Beaker
B) 250 ml Erlenmeyer Flask
C) 250 ml Graduated Cylinder
The answer is B). 250 ml Erlenmeyer Flask
Explanation:
Several types of glasswares are used in chemical laboratories for performing processes like mixing, heating and stirring of chemicals. In this question, Dr. Malani Mackey who works for a pharmaceutical company is trying to develop a cancer drug by making a mixture of L-histidine, polysorbate 80, and sucrose. This mixture is required to be heated and stirred (shaked) during the mixing. Hence, a glassware adapted for this purpose must be used.
- Erlenmeyer Flask, also known as Conical flask is a laboratory flask named after its conical base/bottom. This glassware is used to mix and even heat chemicals in the laboratory. Due to its cone-shaped body coupled with a long cylindrical neck, the contents in the Erlenmeyer Flask can be shaked or stirred without spilling them. This property gives the ERLENMEYER flask an edge over the BEAKER (has a large open mouth) when used for stirring purposes.
The Graduated cylinder is best suited for making precise measurements of liquid chemicals, hence, it is not an appropriate glassware for heating and stirring.

What kind of survivorship curve would result if a group of organisms is producing few offspring but providing good care so their likelihood of survival is high
Answers
The type of survivorship curve that would result if a group of organisms is producing few offspring but providing good care so their likelihood of survival is high is type 1.
What is survivorship curve?Graphs depicting the percentage of a population that lives from one age to the next are called survival curves. These graphs show the mortality of a collection of organisms according to their age.
Ecologists generally gather age-specific survival rates for organisms within a cohort in order to produce survivorship curves.
The early and middle years of life have a high age-specific survival probability, whereas the later years of life see a significant drop in survival.
They are typical of species like humans and many other large mammals, who have few young but take good care of them.
Organisms with type I survivorship frequently have few young and give them good care, which increases the chances of their survival. Almost all mammals, including people, display a type I survivorship curve.
Thus, the kind of given survivorship curve is type 1.
