Explanation:
On your laboratory test, you are presented with a mollusc that has a closed circulatory system. You know immediately that it must belong to the class ________.
Answer:
Cephalopoda
Explanation:
Cephalopods are the mollusk that has a closed circulatory system by simple circulation. The heart is located in the pericardic cavity and it is divided into two auricles and one ventricle. From the ventricle, the anterior aorta goes forward the head and the posterior aorta goes forward the visceral mass. The anterior aorta branches into many branchial arteries. All of them get united again in the head, in one cava vein from where the blood returns to the posterior extreme. This vein introduces into the pericardic cavity and brunches into two renal veins near the nephridium. Each branch penetrates into a nephridial sac and passes through the muscular branchial heart before it enters the gills. Blood passes from the ventricle to the branchia through many vessels. In the branchia, the blood gets oxygenated again and returns to the auricle. The posterior aorta irrigates the gonads and the mantle, and from the posterior extreme of the body, blood goes forward to the anterior body region through two veins that join the renal veins that flow into gill hearts.

Describe the interaction between the farmer, the soil, his corn plants, and the Sun. How does energy flow?
Answer:The farmer uses farm machinery to plot the soil and plant the corn. Energy from the Sun Is stored by the corn plants. When the farmer, animals, or other people eat corn, they gain the energy captured by it.
Explanation:Because it's easy knowledge
Do all organisms rely on the sun for energy
Answer: no
Explanation:
because some plants rely on photosynthesis to survive and they use the suns energy for that but if something does not photosynthesize then it gets energy from food.

c. addition of carbohydrate to proteins to make glycoproteins.
d. the assembly of multimeric proteins.
e. All are endoplasmic reticulum functions.
Answer: Option E.
All are endoplasmic reticulum functions.
Explanation:
All are function of endoplasmic recticulum because
Endoplasmic recticulum is a membrane organelle that consists of two subunits, rough and smooth endoplasmic recticulum found in eukaryotes that formed flattened sacs within the cytoplasm of eukaryotic cells which syntyensises proteins, lipids and steroids, it metabolised carbohydrates by adding it to protein , help to control the concentration of calcium in the body,it detoxifies drugs, attached protein on receptor cells, assemble multimeric proteins e.t.c.
The endoplasmic recticulum comprises of two subunits which are rough and smooth endoplasmic recticulum. The major differences between rough and smooth endoplasmic recticulum is that smooth do not have RIBOSOMES and it produces lipids and rough have RIBOSOMES and produces proteins.

Number of cells in the plant kingdom ?
Explanation:
Hey, there !!
Your question is though because plants are both multicellular and unicellular.
So, let me give you a little idea from whatever i have known.
Inside plant kingdom, there are three divisions,
Thallophyta = composed of mostly unicellular cells.Bryophyta = composed of multicellular cells.Pteridophyta = composed of multicellular cells.These are the information. but if its about type of cells, there are various type of cells such as xylem cells,phloem cells, parenchyma cells, collenchyma cells etc.

A patient visits their doctor because they are having trouble digesting complex carbohydrates. The doctor learns that her patient runs 5-10 miles 5 days a week and drinks very little water. The doctor suggested (before doing any major testing) that the patient begin drinking plenty of water each day. The patient visits the doctor a week later and has no problems with digestion. Why did the doctor suggest such a simple change in habit for her patient?
Answer:
porque el paciente corre una gran distancia pero no toma mucha agua, lo que hace que este se deshidrate, entonces al cambiarlo este se hidrataría mejor ayudando a su condición fisisca

Single-loop circulatory systems have one direction of blood flow. Typically in fish, oxygen is absorbed in the gills, flows in blood to the body organs, and back to the heart, which pumps it directly back to the gills. In double-loop circulatory systems, the heart has multiples of each chamber. Part of the heart pumps blood to the lungs, to get oxygen. This blood flows back to a different chamber where it then gets pumped to the body. Once its oxygen has been used up, it goes back to the heart to be pumped all over again to the lungs.
Freshwater animals have lower water and higher salt concentrations than the environment in their cells. This means water constantly tries to diffuse into the animals, which can bloat them. They have special cell processes that remove extra water.

Dr. riehm shows you an unlabeled tissue slide and says the tissue is very resistant to stretching, tearing, and compression. he then asks you what you can conclude about the structure of the extracellular matrix (ecm)
Answer:
The correct answer would be - The ECM has abundant collagen fibers in a gel-like ground substance.
Explanation:
A tissue that is very much resistance to tearing, stretching and compression would be, due to presence of high amount of the thick bundles of the collagen fibers in its extra cellular matrix. The ground substance of such tissue is gel like.
Fibrocartilage is the tissue which is resist to stretching, compression, and tearing due to its toughness that is comes from thick bundles of collagen fibers in gel like matrix.
Thus, the correct answer is - The ECM has abundant collagen fibers in a gel-like ground substance.

Which of the following heart block dysrhythmias is identified by a repetitious prolonging PR interval pattern after each blocked QRS complex
a) first degree heart block
b) second degree heart block type I
c) second degree heart block type II
d) third degree heart block
Answer: Option A.
first degree heart block
Explanation:
First degree atrioventricular block is a condition that is associated with electrical condition system of the heart in which the electrical impulses is conducted from the cardiac atria to the ventricles via atrioventricular node in a slow manner compare to the normal transmission.
It is first degree great block because it is characterized by prolong PR interval on an electrocardiogram (ECG) to more than 200 msec and atrial impulse is transfered to the ventricles, which lead to regular ventricular rate.
The PR interval of the surface ECG is measured from the start of atrial depolarization (P wave) to the commensement of ventricular depolarization or QRS complex.
