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.
Answer:
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.
Explanation:
What is written above is correct, since humans and primates can communicate in a rustic or not very expressive way with other animals, but understanding or assuming the intentions between different species.
It has been proven that in addition to the ape, chimpanzee and other species of primates, the dolphin is an animal that uses its own language and has a slight percentage of intelligence.

4. The elbow is located _________________ to the wrist.
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.

A researcher investigates an organism found on the ocean floor. The organism is asymmetrical. It lacks a body cavity, body tissues, organs, and a nervous system. The researcher finds that the organism can fully regenerate itself if parts of its body are broken off. Into which phylum should the researcher classify the organism?
The correct answer is option A, that is, Phylum Porifera.
The species of Phylum Porifera are aquatic, that is, mostly marine. They exhibit cellular grade of the body, they are diploblastic animals with asymmetrical symmetry. They lack body cavity and exhibits a holozoic mode of nutrition with intracellular digestion.
They lack circulatory and nervous system and possess the tendency to regenerate their parts of the body. The organisms in phylum Porifera exhibits both asexual and sexual mode of reproduction.

The ability of metabolically active tissue (e.g. muscle) to change energy sources from fat to carbohydrates (and vice versa) is termed
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.

The presence of the following is a necessary requirement for producing beta galactosidase: lactose, lacI+, lacZ+, and lacO+. Since there is a constitutive operator present, it will not let the repressor protein bind, beta galactosidase production will constitutive as well - though at a lower rate because the other operator is wildtype.
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
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.

Explanation:
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).
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.
