Dinobryon is a species of protozoa that reproduces asexually. How can this asexual reproduction be harmful to the species?

Answers

Even though the asexual way of reproducing has its advantages (it can be fast, it spends less energy and eliminates the search for a partner) it can be harmful to the species' genetic variability. When an organism reproduces asexually all of the offspring are genetic clones of the parents. This can lead to a decrease in the genetic variability of the population, making it unable to change, evolve and respond to the changes in its environment.

In what way do the respiratory and circulatory systems depend on each other

Answers

The circulatory system consists of an entire network of blood cells that is being pumped in the entire body throughout and the respiratory system has the main function to exhale carbon dioxide and inhale oxygen for providing energy.

Both circulatory and respiratory systems work together for transportation of oxygen to all the organs and muscles of the body. The heart pumps the oxygen rich blood from lungs and excretes or disposes the waste in the blood to the lungs to breathe and exhale out of the body.

Cells that perform a specific function:

Cell serves as the basic building blocks for building the structure or the body of the living organisms. Now, certain type or specific number of cells come closer and arrange themselves in such a sequence that they need to perform a unique or specific task by making up a whole organ structure.

Explanation:

Example of cells that perform the specific function inside the living organisms body:

There are certain cells inside the human body which makes up a single organ and then performs the whole function specifically by themselves, as we have the "myocardial myocytes".  These are the specific type of cells which are required for the heart's cardiac muscles to develop or grow in a given pattern. As these cells are specialized for making up or building up of the cardiac muscles which in turns results in the heart structure. And performs the basic function of supply of blood and the required materials i.e nutrients to the different cells and organs.

The head of a giraffe is 2.0 m above its heart and the density of the blood is 1.05 103 kg/m3. what is the difference in pressure between the giraffe's heart and head? (fortunately, a giraffe's neck has a special circulatory system to adapt to this neck length, producing an even flow of blood to the head.)

Answers

The giraffe head is higher than its heart so the blood pressure in the head must be lower than in the heart. The pressure is directly related to the density, gravity, and the height. The calculation would be:

P = ρ*g*h 
P= 1.05* 10^3 kg/m3 * 9.8m/s2 * 2m= 20 580 pascals= 20.58 kpa

The difference in pressure between the giraffe's heart and head is :

20.58 kPa Position of Giraffe head in relation to its heart

Given that the head of the giraffe head is placed at a higher position the blood pressure in the head will be higher than the blood pressure in the heart. and

Pressure in the Giraffe is directly related to ; density , gravity and height of the giraffe

Therefore pressure = ρ*g*h

                                 = 1.05 * 10³ * 9.8 * 2

                                 = 20580 pa  = 20.58 kPa

Hence we can conclude that the difference in pressure between the giraffe's heart and head is 20.58 kPa.

Answers

Final answer:

Absorption is the biological process where digested nutrients are taken into the bloodstream, mainly occurring in the small intestine.

Explanation:

Absorption in the context of biology, particularly the digestive system, refers to the process in which substances pass into the bloodstream or lymph system to circulate throughout the body. After food is broken down into small nutrient molecules through mechanical and chemical digestion, the molecules are absorbed by the blood. This process primarily takes place in the small intestine, where nutrients are assimilated into the body to be used for energy, growth, and repair.

You traced a molecule of urea from the renal artery out of the body. how would the steps of this tracing differ if the urea were recycled

Answers

Blood entering glomerulus carries urea molecule, and the molecules are filtered through Bowman's capsule and then it enters the proximal convoluted tubules. The half of incoming urea is being reabsorbed and it enters the loop of Henle's. Urea is being secreted in thin limbs of a loop from the medulla into the lumen of the tubules increasing urea concentration to hundred percent.
From loop, the urea enters to distal convolated tubules (DCT) being hundred percent. In distal convoluted tubules, thirty percent is reabsorbed to cortex while the remaining seventy percent enters to collecting tubules. Fifty percent is being reabsorbed in the medulla. Fifteen percent is excreted as urine, the five percent is reabsorbed by vasa recta and arteries which are associated with nephron.
The urea recycling traps most of the urea in the medulla and it creates high osmolarity which helps in water reabsorption.

Natural selection is a nature-made selection, and artificial selection is a man-made selection. Natural selection is the work of nature itself and no human interaction is involve in this process. Plants and animals breed according to the flow of nature. While on the other hand artificial selection produces diversities of organisms such as improved crops and livestock.

what chemical compound is crucial to marine life and how it is disappearing

Answers

The answer is nitrogen. It is usually regarded as a growth-limiting factor for primary producers such as phytoplankton. It is usually taken up in the ‘fixed’ form of ammonium. It is converted from dissolved nitrogen gas in ocean surface to a ‘fixed’ form by particular microbes. Due to increasing global temperatures, as a result of global warming, the ocean temperatures have increased hence oceans hold less dissolved oxygen than they used to. The low oxygen concentration in the oceans induces the loss of nitrogen from oceans through increased activity of micro-organisms that are significant in denitrification. This rate becomes higher than that of nitrification that fixes nitrogen in the oceans.   

Which other system in the body works closely with the kidneys to regulate arterial blood ph?

Answers

The correct answer is the respiratory system.

The pH of the extracellular fluids (blood) can be controlled by separately regulating the partial pressure of CO2, which determines the carbonic acid concentration via respiration and the bicarbonate ion concentration in the extracellular fluids via renal system. Control of the carbonic acid concentration in the blood is achieved by changes in the rate and depth of breathing. Breathing releases or retains CO2 (and thus carbonic acid) in the blood plasma and thus, changes its pH.
