Using technology in the field of agriculture which has enabled farmers to feed a growing human population is an example of a beneficial use of technology.
Answer:
This statement is true
Explanation:
Technologies associated with agriculture systems have greatly enhanced crop yields around the world. An example of this is the "Green revolution" in 1950-1960, where the combination of genetic improvement methodologies with the use of fertilizers was critical for the amazing increase in crop yields, particularly in new varieties of rice and wheat. Indeed, the agronomist who developed some of these high yielding varieties of wheat, Norman Borlaug, was awarded the Nobel Peace Prize for his contribution to the extensive increase in crop production, thereby helping to alleviate world hunger.

Dr. Malani Mackey, works for a pharmaceutical company developing a drug for treating skin cancer. 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.
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.

\ would you be injured if you pulled a muscle in your axillary region, cracked a bone in your occipital region, or cut a digit?
Answer:
yes you will be injured.
Explanation:
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.
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.

C. Moves things in and out of cells
D. Makes cells waterproof
Answer: c
Explanation:
Function of protein macromolecule is to move things in and out of the cells.
What are proteins?
Protein is found throughout the body in muscle, bone, skin, hair, and virtually every other body part or tissue. It makes up the enzymes that power many chemical reactions and the hemoglobin which carries oxygen in your blood. At least 10,000 different proteins make up the human being.
Protein is made from twenty-plus basic building blocks called amino acids. Because body does not store amino acids, our bodies make them in two different ways: either from scratch, or by modifying others. Nine amino acids—histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine are known as the essential amino acids, and must come from food.

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.
The meq is a unit used in biology to represent the ionic concentration of a solution.

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.

Which statement best describes the movement of carbon dioxide into or out
of a plant during photosynthesis?
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 morphological difference is associated with C4 plants but not C3 plants?
A. Stomata in the lower epidermis
B. Spongy mesophyll cells
C. Xylem
D. A waxy coating of the bundle sheath
Answer:
Explanation:Answer:
D. A waxy coating of the bundle sheath
Explanation:
C3 plants are plant that make use of Calvin cycle for synthesising their food while C4 plants makes use of Calvin cycle along side a 4 carbon compound that help store carbondioxide.
The C4 plant is unique because it has both mesophyll cell and bundle sheath unlike C3 plant that has only the mesophyll cell. The bundle sheath is where the 4 carbon compound that ferried carbondioxide is first stored before in form of oxaloacetate before broken down cell into pyruvate and carbondioxide and now proceed into the Calvin cycle for the formation of sugar in the bundle sheat.
The bundle sheat and mesophyll cell help separate when carbondioxide is ferried in and when it is used up for sugar formation in C4 plants.
A store sells a variety of sets for building molecular models. The sets are described by the diagram below. Each circled letter represents a box of 6 model atoms of one element. For example, the circled letter "P" represents a box with 6 model phosphorous atoms.
Set 1 has 12 carbon, 12 oxygen, and 18 hydrogen atoms. Set 2 has 12 carbon, 12 oxygen, and 24 hydrogen atoms. Set 3 has 6 carbon, 12 oxygen, 12 hydrogen, 6 nitrogen, and 6 phosphorous atoms. Set 4 has 6 carbon, 6 oxygen, 6 hydrogen, and 6 phosphorous atoms.
Kendra wishes to build a model of a carbohydrate molecule, ideally containing as many monomers as possible. Which set should she choose?
A. Set 1
B. Set 2
C. Set 3
D. Set 4
Answer:
B. Set 2
Explanation:
Carbohydrate is one of the four biological molecules in living systems (others are proteins, lipids and nucleic acid). The carbohydrate molecule consists of a long chain of carbon, hydrogen and oxygen elements in a ratio 1:2:1. Hence, the simplest unit of a carbohydrate has an empirical formula of (CH2O)n where n is the number of chains.
According to the question, a store sells a variety of sets for building molecular models and Kendra wishes to build a model of a carbohydrate molecule. Since carbohydrate monomers have a CH2O formula, Kendra needs a set in which the ratio of carbon: hydrogen: oxygen is 1:2:1. SET 2 fits this description by containing 12 carbon, 12 oxygen, and 24 hydrogen atoms
That is, carbon (12/12) : hydrogen (24/12) : oxygen (12/12), which is 1:2:1. Therefore, SET 2 is the best choice for Kendra in order to build her model of carbohydrate molecule containing as many monomers as possible.
