part A
A sample of gold has mass of 38.6 grams and a volume of 2 cm3 what is the density of gold?

Part B
A sample of iron has a mass of 46.8 grams and a volume of 6 cm3 what is the density of iron?

Answers

Answer 1

Considering the definition of density, you obtain that:

Part A: the density of gold is 19.3 g/cm³.Part B: the density of iron is 7.8 g/cm³.

Definition of density

Density is defined as the property that allows to measure the amount of mass in a certain volume of a substance.

The expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density= mass÷ volume

It can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

Density in this case

In this case, you know that:

A sample of gold has mass of 38.6 grams and a volume of 2 cm³.A sample of iron has a mass of 46.8 grams and a volume of 6 cm³.

Replacing in the definition of density:

Gold: density= 38.6 g÷ 2 cm³Iron: density= 46.8 g÷ 6 cm³

Solving:

Gold: density= 19.3 g/cm³Iron: density= 7.8 g/cm³

In summary, the density of gold is 19.3 g/cm³ and the density of iron is 7.8 g/cm³.

In the autonomic nervous system, neurotransmitter activation of its receptor terminates when the neurotransmitter is broken down by enzymes or when it diffuses away. Which other mechanism leads to termination of neurotransmitter activity?.

Answers

Other than the autonomic nervous system, active transport into surrounding cells leads to terminations of neurotransmitter activity.

The ANS is responsible for the termination of the neurotransmitter activations which are held by enzymes. The peripheral nervous system's autonomic nervous system (ANS), originally known as the vegetative nervous system (VNS), provides smooth muscle and glands, which in turn affects how internal organs work.

The autonomic nervous system is a mechanism that governs body processes including heart rate, digestion, respiration, pupillary response, urine, and sexual arousal mostly subconsciously. The fundamental mechanism in charge of the fight-or-flight response is this system. Through the brain stem, the spinal cord, and the organs, integrated reflexes control the autonomic nervous system.

Control of breathing, cardiac regulation (the cardiac control center), vasomotor activity (the vasomotor center), and other reflex acts including coughing, sneezing, swallowing, and vomiting are all examples of autonomic activities.

Christian Bergmann Hypothesis

Bears living in warmer regions, polar bears have massive, compact bodies that provide a smaller relative surface area (relative to volume) for heat loss.

Why hunting is more suited for larger animals in cold climates?

Compared to smaller animals, larger and heavier animals are more suited for hunting.

Answers

Genetic variations account for a sizable portion of variation in migratory behaviour as well as in physiological and morphological adaptations to migration. Comparative research indicates that various lineages have separately and quickly evolved migratory behaviour.

In evolutionary time, migration will often quickly converge gene frequencies among populations. Migration is a powerful mechanism for balancing the gene frequencies of subpopulations in a species in the absence of selection. Gene frequencies will ultimately equalise if the migration rate is larger than zero.

Which of the following organs is incorrectly paired with its function? a. stomach-protein digestion b. large intestine-bile production c. small intestine-nutrient absorption d. pancreas-enzyme production

Answers

The correct option is (b) Large intestine-bile production

Bile production if from liver and not from large intestine.

Bile, which is created in the liver and kept in the gallbladder, is released when chyme enters the duodenum due to hormonal reactions. By emulsifying lipids, particularly triglycerides, bile facilitates their digestion. Large lipid globules are split up into a number of smaller lipid globules by a process called emulsification. In the chyme, these tiny globules are more evenly dispersed than they are in larger aggregates. Since lipids are hydrophobic molecules, they will group together to form globules in order to reduce their exposure to water. Bile salts, which include both hydrophobic and hydrophilic components, are amphipathic and are found in bile. As a result, the hydrophilic side of bile salts can interact with water on one side and lipids on the other. Bile salts do this by breaking down large lipid globules into smaller lipid globules.

Voltage-gated sodium channels play a critical role in electrogenesis, and variables that reduce their activity can have a significant impact on axonal conduction. In fact, numerous distinct therapeutically beneficial medications, including local anesthetics and anticonvulsants, reduce neuronal excitability by inhibiting the activation of voltage-gated sodium channels.

Answers

Antagonistic effects of the same organ are observed when parasympathetic and sympathetic innervation is present in it.

The parasympathetic division and the sympathetic division are two diametrically opposed divisions of the autonomic nervous system that control homeostasis. Most of the body's organs are innervated by both the sympathetic and parasympathetic systems, which work against one another to maintain normal physiology including blood pressure, blood oxygen levels, and nutrition levels. Each scenario necessitates a different level of effort on the part of a certain organ to maintain homeostasis. Additionally, certain organs must function in order to get the body ready for potential future circumstances. The autonomic nervous system controls each and every one of these processes.

The autonomic nervous system prepares the body for stressful conditions is the sympathetic division. This mechanism is frequently referred to as "fight or flight." Among the many impacts of this system are elevated heart rate, constricted blood arteries to the skin and viscera (raising blood supply to the muscles), enlarging pupils, and reduced salivation. All of these reactions encourage surviving in a hazardous circumstance.

The parasympathetic branch of the autonomic nervous system, sometimes known as the "rest and digest" system, gets the body ready for settings that allow for rest. The parasympathetic nervous system slows heart rate, increases gastrointestinal motility, and increases salivation, among other things. By conserving nutrients, these reactions aid the body's ability to recuperate and become ready for stressful conditions.

The walls of alveoli contain elastic fibers that allow the alveoli to expand and contract with each breath. If the alveoli lost their elasticity, how would that affect gas exchange in the lungs?

Answers

Some elastic and collagen fibres can be found in the alveoli. The alveoli may extend when they fill up with air during inhalation thanks to the elastic fibres.

What occurs when the alveoli become less elastic?

The lungs also enlarge inside the chest cage due to the loss of elastic tissue from the walls of the damaged alveoli. Small bronchi are compressed by the enlarged lungs, which raises airflow resistance.

Reduced alveolar elastic fibres will result in less elastic rebound, but diminished alveolar attachments to the airways will result in diminished support for the small airways and increased constriction of the small airways during expiration.
