External intercostals contract to elevate the ribs during inhalation while internal intercostals contract to depress the ribs during forced exhalation.
Inhalation and exhalation constitute the process of respiration.While inhalation is simply the act of breathing in, exhalation is the exact opposite, breathing out.
The intercostal muscles are muscles situated in between the ribs of an animal or a person. It is separated into:
external intercostals which are responsible for elevating the ribs when they contract during inhalation andthe intercostal muscles which play a role in depressing the ribs during exhalation.To learn more about muscles, see: https://brainly.com/question/9883108?referrer=searchResults

'DNA' is usually defined as: deoxyribonucleic acid: an extremely long macromolecule that is the main component of chromosomes and is the material that transfers genetic characteristics in all life forms, constructed of two nucleotide strands coiled around each other in a ladderlike arrangement with the sidepieces composed of alternating phosphate and deoxyribose units and the rungs composed of the purine and pyrimidine bases adenine, guanin, cytosine, and thymine: the genetic information of the DNA is encoded in the sequence of the bases and is transcribed as the strands unwind and replicate.
Other options:
What are ribosomes?A cell organelle constructed in the nucleolus and functioning as the site of protein synthesis in the cytoplasm; consists of rRNA and protein molecules, which make up two subunits.
What is protein?Any of the numerous, highly varied organic molecules constituting a large portion of the mass of every life form and necessary in the diet of all animals and other nonphotosynthesizing organisms, composed of 20 or more amino acids linked in a genetically controlled linear sequence into one more polypeptide chains, the final shape and other properties of each protein being determined by the side chains of the amino acids and their chemical attachments: proteins include such specialized form of collagen for supportive tissue, hemoglobin for transport, antibodies for immune defense, and enzymes for metabolism.
What is the mitochondria?An organelle in the cytoplasm of cells that function in energy production.

What about Earth allows it to maintain bodies of water?
OA. Weak gravity and high temperatures
OB. Moderate temperatures and strong gravity
C. Strong magnetic fields and lunar tides OD. Comet crashes and mountains
Answer:
Letter C is correct
Explanation:
Earth's moderate temperatures allow water to exist in all three states: solid, liquid, and gas. Its strong gravity keeps the water from escaping into space. Hence option B is correct.
The other options are not correct. Weak gravity would not be able to hold water on Earth, and high temperatures would cause the water to evaporate.
Strong magnetic fields and lunar tides do play a role in shaping Earth's oceans, but they are not the primary factors that allow Earth to maintain bodies of water.
Here are some other factors that help to maintain bodies of water on Earth:
The Earth's atmosphere, which traps heat and prevents the water from freezing.
The Earth's rotation creates the Coriolis force, which helps to distribute the water evenly around the planet.
The Earth's tilt, which causes the seasons, affects the amount of sunlight that reaches different parts of the planet and affects the temperature of the water.
Therefore, option B) Moderate temperatures and strong gravity are correct.

While doing the Osmosis, Effect of Solute Concentration experiment, forgetful Frank left his bag with 10% sucrose in the beaker of water for 2 hours instead of one, how would his results be different from the rest of the class?
The effect is that Frank's 10% sucrose bag will be heavier than that of others.
OsmosisWater molecules move from the region of lower solute concentration to the region of higher solute concentration.
Thus, water will continue to enter into a 10% sucrose bad dropped in a beaker of water until an equilibrium is established between the 2 media.
This means that the longer the bag stays in the beater containing water, the more the water will enter, and the heavier it will weigh.

Predator protection
Photosynthesis
The main function of fungus’s hyphae is the Absorption of nutrients by the fluttery filaments that make up multicellular fungi are called hyphae. As they consume resources from a food source, they release enzymes.
What are the fungal hyphae?The fluttery filaments that make up multicellular fungi are called hyphae. As they consume resources from a food source, they release enzymes. Chitin makes up the rigid cell wall of hyphae. In pursuit of more food sources, they spread out from a tip and continue to expand.
The substrate is broken down by digestive enzymes secreted by the hyphae, which makes it simpler for the fungus to absorb the nutrients it contains. The fungus has a very wide surface area compared to its volume, which indicates that it is in close contact with its surroundings.

Propane is burned to provide the heat in many cooking grills. The chemical
reaction for this process is shown in the equation below.
C3H8 +502 → 3 CO2 + 4H2O + energy
What are the products in this chemical reaction?
A. C3H8 +502
B. 4H₂0 +502
C. 3C0₂ + 4H₂O + energy
D. C3H3 +3CO2 + energy
Answer: it's 3CO2+4H2O+Energy
Propane is a linear alkane of formula C3H8. It is mainly used as fuel (this is the main component of liquefied petroleum gas) in cooking and chemical industry reactions.
The reaction of its complete combustion by the presence of oxygen is:
C3H8 (gas) + 5O2 ==> 3 CO2 + 4H2O + energy (2220⋅kJ)
As we can see, propane can release carbon dioxide and water as every combustion reaction, and a lot of energy in the form of heat.
