When humans workout for a long period of time, the body's muscles may become sore. What process occurred in the muscle cells that made them sore?
Answer:
When muscles are required to work harder than they're used to or in a different way, it's believed to cause microscopic damage to the muscle fibres, resulting in muscle soreness or stiffness. DOMS is often mistakenly believed to be caused by a build up of lactic acid, but lactic acid isn't involved in this process.

Explanation:
List five cell organelles and describe their function.
Answer:
Ribosomes are tiny organelles that contain RNA and specific proteins within the cytoplasm. Within the cell, ribosomes are directly involved in the manufacture of proteins by using their RNA and amino acids.
This process involves decoding the information contained in the mRNA and using amino acids to produce the required proteins.
Mitochondria are some of the largest organelles within a cell.
Compared to some of the other organelles, mitochondria contain DNA which makes them semiautonomous. Mitochondria also contain a double-membrane with the inner membrane folding to form cristae.
Also known as the powerhouse, mitochondria play an important role in respiration where they generate ATP (adenosine triphosphate) from substrates in the presence of oxygen. Using their DNA, mitochondria are able to encode for some of the components they require to perform their functions.
The plasma membrane is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell.
As such, it is actively involved in such both passive and active transportation to and from the cell. These processes also help maintain balance even when conditions outside the cell change.
The plasma membrane is made up of two layers of phospholipids (phospholipids bilayer).
Found in eukaryotic cells, Endoplasmic reticulum (ER) is the organelle that forms an interconnected network of flattened sacs (cisternae). Like some of the other organelles found in eukaryotes, ER is enclosed in a membrane. The ER is divided into two regions that vary in structure and function.
These include:
Smooth endoplasmic reticulum - The smooth ER is named so because it lacks a ribosome on its surface. As a result, it is more smooth in appearance as compared to the rough ER. It is involved in the synthesis of lipids (e.g. phospholipids) and carbohydrates that are used to build the cell membrane.

Hydrofluorocarbons (HFCs) were used to phase out chlorofluorocarbons (CFCs), which were used as aerosol propellants, refrigerants, and coolants. Members from 197 nations meeting at the summit of the United Nations Environment Programme in Kigali, Rwanda reached a legally-binding accord to phase out HFCs in an amendment to the Montreal Protocol due to HFCs potential for A) global warming. B) increased cancer incidence. C) toxicity and biomagnification in aquatic ecosystems. D) contributing to habitat destruction of endangered animals.
Answer:
Members from 197 nations meeting at the summit of the United Nations Environment Programme in Kigali, Rwanda reached a legally-binding accord to phase out HFCs in an amendment to the Montreal Protocol due to HFCs potential for global warming.
Explanation:
The Phase-out Management Plan (HPMP) for Hydrochlorofluorocarbons (HCFCs)
Under the Montreal Protocol on Substances Depleting the Ozone Layer, in particular the Executive Committee (ExCom) 53/37 and ExCom 54/39, the Parties to this Protocol agreed to set 2013 as the time for developing countries to freeze consumption and development of HCFCs. For developing countries, the decline in consumption and production of HCFCs started in 2004 and 2010, respectively, with a decline of 100% set for 2020. Developing countries have agreed to start reducing their HCFC consumption and output by 2015, with a reduction of 100% set for 2030.
Hydrochlorofluorocarbons are a category of man-made compounds containing hydrogen, chlorine , fluorine and carbon, generally referred to as HCFCs. In nature, they are not found anywhere. After countries decided to phase out the use of CFCs in the 1980s, which were found to be damaging the ozone layer, HCFC production began to take off. HCFCs are used for refrigeration, aerosol propellants, foam processing and air conditioning, much like CFCs. However, unlike CFCs, most HCFCs in the lowest part of the atmosphere are broken down and pose a much smaller danger to the ozone layer. Nonetheless, considering their very low atmospheric concentrations, HCFCs are very potent greenhouse gases, measured in parts per trillion. Compared to CFCs with ODP 0.6-1.0, these HCFCs have lower ODPs (0.01-0.5) in terms of ozone depletion potential (ODP). Compared to CFCs with a GWP of 4,680-10,720, HCFCs have lower GWPs (76-2,270) in terms of global warming potential ( GWP).
Hydrofluorocarbons (HFCs), manufactured mostly in developing countries, have replaced CFCs and HCFCs. HFCs do not cause damage to the ozone layer because they do not contain chlorine, unlike CFCs and HCFCs. However, they are greenhouse gases, similar to that of CFCs and HCFCs, with a strong global warming potential ( GWP).
In the other three options ,there is no role of the members from 197 nations meeting at the summit of the United Nations Environment Programme in Kigali.
Hence, the correct option is A.

Which characteristic best explains why lotic ecosystems tend to have more dissolved oxygen than lentic ecosystems?
Lotic ecosystems tend to be warmer, which increases dissolved oxygen levels.
Lentic ecosystems contain still water, which decreases the solubility of oxygen.
Lentic ecosystems tend to have a larger variety of species using up the oxygen.
Photosynthetic organisms use most of the dissolved oxygen in lentic ecosystems.
Which characteristic best explains why lotic ecosystems tend to have more dissolved oxygen than lentic ecosystems?
⋆Lotic ecosystems tend to be warmer, which increases dissolved oxygen levels.
⋆Lentic ecosystems contain still water, which decreases the solubility of oxygen. ✓
Lentic ecosystem ,due to having still water bodies which are comparatively smaller than the waterbodies in lotic ecosystem, evaporates faster so does cools down , resulting in more dissolved oxygen than that in a lentic ecosystems.⋆Lentic ecosystems tend to have a larger variety of species using up the oxygen.
⋆Photosynthetic organisms use most of the dissolved oxygen in lentic ecosystems.
The characteristic that best explains why lotic ecosystems tend to have more dissolved oxygen than lentic ecosystems is lentic ecosystems contain still water, which decreases the solubility of oxygen. The correct option is b.
What are lentic and lotic ecosystems?Lotic ecosystem refers to environments with flowing water, such as rivers and streams, lentic (from the Latin lentus, meaning sluggish or motionless), refers to standing waters such as lakes and ponds (lacustrine), or swamps and marshes (paludal).
Examples of Lentic ecosystems are ponds, marshes, etc. and examples of lotic ecosystems are streams and rivers. Rivers are always moving and ponds are still.
Therefore, the correct option is b. Still, water is a component of lentic ecosystems, which reduces oxygen solubility.
