The video with the necessary information to answer the question is missing. So, an irrigation system definition and example will be given.
An irrigation system is a structure made of tubes, hoses, and sprinkles; Its function is to water plants or crops with the correct amount of water and in an evenly way.
A simple irrigation system that will help grow plants at home is a plastic bottle with small holes connected to a hose with a tube that can lead the water from the hose to the bottle without losses. The bottle with its holes works as a sprinkler.
In conclusion, irrigation systems are in lawns, fields, or gardens, and they water the plants evenly so that they can grow. There are many types, but we can build a simple one with a bottle.

The organelles of eukaryotic cells interact with each other to maintain homeostasis within the cell. The nucleus, endoplasmic reticulum, Golgi apparatus, chloroplasts, and mitochondria all contribute to protein transport, packaging, export, and energy harnessing. According to the endosymbiotic theory, certain organelles are proposed to have evolved from free-living bacteria that were engulfed by a larger cell. These organelles have multiple membranes, their own circular DNA, and can replicate by binary fission. The origin of which organelles are likely explained using the endosymbiotic theory?

cytochrome c is a protein found in all species, and functions in energy metabolism. the more closely related two different species are,
Answers
The more closely related two different species are, the more alike their cytochrome C amino acid sequences are. The cytochrome C is an evolutionarily conserved protein.
The cytochrome C is an evolutionarily conserved protein involved in cellular respiration.
The cytochrome C is a carrier of electrons that acts during the oxidative phosphorylation stage of cellular respiration.
This protein is evolutionarily conserved in species whose cells generate ATP in anaerobic (oxygen presence) conditions, which means that generally synonymous mutations are observed when comparing the amino acids of this protein.

The body is supported by its skeletal structure. It gives the body form, motion, and shape while safeguarding delicate organs. The body is supported by its skeletal structure.
What is skeletal system?The main structural component of your body is the skeletal system. It is made up of bones and connective tissue, such as ligaments, tendons, and cartilage.
Vertebrates are creatures with a spinal column or backbone, including humans. They are supported by a strong internal framework that is built around a noticeable spine.
Our bodies' living bones use oxygen and release waste products throughout metabolism. They have functional tissues that require nutrients, blood flow, and the ability to remodel or change shape in response to changes in mechanical stress.
The skeleton, which is made up of bones, acts as a rigid framework to support and shield the body's soft organs.

According to the food chain shown, about how much energy from the grasshopper trophic level is transferred to the frog trophic level?
Answers
The amount of energy transferred to frog is 10% of the energy contained in grasshopper.
This is a representation of energy levels and distribution in a food chain in an Ecosystem. When a group of organism represent the same level in a food chain, in an ecosystem ,this is trophic level. Food chain represent a linear representation of nutrients and therefore energy distributions in an ecosystem.
Basically, in an ecosystem, there is always reduction in energy transfer from one trophic level to another by 10%. This is because, as the energy is transferred from the producer (green plants) to the primary consumer, the hopper, only 10% of the available energy will pass through to the hopper because 90% of the energy will be used by the green plants for metabolic and other physiologic activities. As this is transferred to the next trophic level, the Frog, this will be reduced (for the same reasons) so that 10% of the energy received by the grasshopper is transferred to the frog.
Practically, if 100,000Kcal of energy was obtained by hopper from the primary producer,10,000kcal(10%) of 100,000 will be transferred to frog.
This 10% occurs at each trophic levels.

illustrate how the self sealing bubble membrane helps to illustrate the passage of molecules through a cell membrane and the property of selective permeability
Answers
Self-sealing bubble membranes help to illustrate the passage of molecules and the property of selective permeability in that they are an example of how something can be semi-permeable and allow only some substances to pass.
When we mention a membrane, we refer to the selective barrier that protects cells from the environment. Within this barrier, lie certain proteins that serve as a kind of "tunnel" for the passage of very specific substances. This, along with a few other mechanisms are what gives a membrane the title of being semi-permeable.
This is because semi or selective permeability is the ability to allow the passage of very specific substances despite being a sealed barrier. Self-sealing bubble membranes share this ability by allowing some substances, like specific gases, to enter the bubble while others will remain on the exterior of the sealed barrier.
