Cells are made of organelles, specialized structures that each perform specific functions that help the cell maintain
homeostasis. This is much like the body systems work together to help the body maintain homeostasis. Consider each
of the organelles and body systems paired below. Which pairs perform similar functions? Select ALL four that apply.
A)
nervous system: nucleus
B)
digestive system: lysosome
circulatory system: ribosome
D)
respiratory system: mitochondria
E)
integumentary system: cell membrane
Answer:
A) Nervous system; nucleus
B)Digestive system; lysosome
D)Respiratory system; mitochondria
E) Integumentary system ; cell membrane
The pair that perform similar functions are nervous system: nucleus, digestive system: lysosome, respiratory system: mitochondria, integumentary system: cell membrane. The correct options are a, b, d, and e.
What is homeostasis?The state of constant internal, physical, and chemical conditions maintained by living systems is known as homeostasis.
This is the state of the organism's optimal functioning, and it includes many different factors, such as core temperature and adequate fluid, being kept even within those pre-set limits.
Homeostasis is the state of balance within all physical systems required for a body to function properly and survive.
The nervous system and nucleus functions the same, as the nervous system makes control and co-ordination with whole body, nucleus also controls all cell's activities.
Digestive system works by breaking down the food and making it into its simplest form, just like that lysosomes also bears digestive enzymes.
Just like respiratory system produces energy by oxidation of food, mitochondria also provides energy to cell by generation of ATP.
The integumentary system is the protection layer of the body that prevents outside material to come inside or vice versa, just like cell membrane of the cell.
Thus, the correct options are a, b, d, and e.

Propane (C3H8) burns in oxygen to produce carbon dioxide gas and water vapor.
Write a balanced equation for this reaction.
Calculate the volume of propane measured at STP that could be produced from 21.13 g of propane.
Answer:
11.6 L will be the number of liters of carbon dioxide measured at STP.
Answer:
I can help. I don't think this should go in Biology, but eh whatever.
Explanation:
1. Write a balanced equation for this reaction.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We have propane (C3H8) that burns in O2(g) to form CO2(g) and H2O(g)
We have to write an unbalanced combustion
C3H8(g) + O2(g) ---> CO2(g) + H2O(g)
Then we have to balance it:
C3H8(g) + 5 O2(g) ----> 3 O2(g) + 4 H2O(g)

Tears of the ligaments that hold joints together (Rapidly changing headings, such as cutting or turning maneuvers, which puts unordinary weight on the knee causing the tendon to extend or tear Landing clumsily on the knee, which may happen after a bounce in volleyball or basketball)
Tears of the tendons that support joints and allow them to move (Most tendon wounds are the result of progressive wear and tear to the ligament from abuse or maturing. Anybody can have a ligament damage. But individuals who make the same movements over and over in their occupations, sports, or day by day exercises are more likely to harm a ligament. A ligament harm can happen abruptly or small by small.)

Why lapse in managing supplier can tarnish the buyer's reputation?
Answer:
yep
Explanation:
notthing
The lapse in managing suppliers causes buyer shortages or the sale of poor quality products that cause customer dissatisfaction and tarnish the buyer's reputation.
We can arrive at this answer because:
Buyers are companies and stores that buy products or materials from suppliers to supply them to customers.Buyers and suppliers have a very well-established business relationship, as the success of buyers depends on good supplier management.Poor management causes suppliers to delay deliveries and provide poor-quality materials to buyers.These problems will be passed on to the customer, who will blame the buyer and could damage the buyer's reputation.In other words, we can say that the poor management of suppliers damages the buyer's reputation because this promotes poor service to the customer's needs, which will blame the buyer for these problems.

describe the uptake and movement of water from the soil to the leaves
Answer:
After traveling from the roots to stems through the xylem, water enters leaves via petiole (i.e., the leaf stalk) xylem that branches off from that in the stem. Once water leaves the xylem, it moves across the bundle sheath cells surrounding the veins.1-Water is passively transported into the roots and then into the xylem. 2-The forces of cohesion and adhesion cause the water molecules to form a column in the xylem. 3- Water moves from the xylem into the mesophyll cells, evaporates from their surfaces and leaves the plant by diffusion through the stomata.Plant water uptake, or transpiration, represents the process by which water in soil is drawn into plants and returned in gaseous form to the atmosphere through leaf stomata.Water transport also occurs at the cellular level, as individual cells absorb and release water, and pass it along to neighboring cells. Water enters and leaves cells through osmosis, the passive diffusion of water across a membrane.Most of the water that a plant takes in enters through the root hairs.

Amelia has laid the groundwork for a fledgling business and is considering incorporating. Which of the following
is a valid concern that she might have?
A) Acquiring financing as a corporation will be much more challenging than it is for other
business structures.
B) Incorporating comes with an increase in liability compared to other business structures.
C) The regulations will be more burdensome than in other business structures.
D) The corporation will only last as long as she is able to work
A valid concern that Amelia might have is C. The regulations will be more burdensome than in other business structures.
A corporation refers to an organization that is authorized to act as a single entity. A corporation is a legal entity and is distinct from its owners.
It should be noted that under law, corporations can loan and borrow money, enter contracts, sue, own assets, etc. The purpose of a corporation is to make a profit.
The concern for Amelia will be the fact that a corporation is highly regulated. It's usually monitored by government agencies. There are also regulations that are put in place in order to protect the rights of employees. Therefore, this may be a challenge for Amelia since she may not have the freedom like that of a sole proprietor.

which objective lens will still remain in focus when placed at the longest working distance from the specimen?
Answer:
10x objective lens
Explanation:
The objective lens that will still remain in focus when placed at the longest working distance from the specimen is 10x objective lens.
Microscope objectives are set up with a short free working distance. Working distance is knot to be the point or distance from the front lens element of the objective to the closest surface of the coverslip when the specimen is in sharp focus.
The distance between the objective lens and the specimen, when the specimen is in focus, is called the working distance of the lens. The greater the magnification of the lens, the less the working distance; that isConclusively, a 10x objective lens is a low power objectives that has a longer working distances than high power objectives
