Thank you!!!!!!!
Answers
Answer:
1.A tissue is a collection of similar cells that work together to perform a specific job.
An organ is a collection of different tissues that work together to perform a specific job. The function of a part of an organism is what it actually does (it's job)
2.The structure of the alveoli as a web of blood vessels surrounding an air sac allows blood cells take in oxygen and bring it into the lungs (organ)
Answer:
1. All animals have tissue
Animals have to have organs to live
All animal cells have a specific function
2. Alveoli are tiny sacks who function is to contain and exchange gases such as oxygen and carbon dioxide. the structure of alveoli, as tiny sacks surrounded by tiny blood vessels includes the cells that make up the tissue of the alveoli and the tissue that joins alveoli to the bronchioles, which are part of the lung. the lungs are made of several kinds of tissue, such as the bronchi, bronchioles, and alveoli

If all of the characteristics of life are required to classify something as “alive”, how can we account for those individuals who are definitely alive, but that do not reproduce (for example, people without children or a sterile mule)?
Answers
Answer:
Here is the answer key. Just scroll down to the question and the answer is there.
Explanation:
These organisms are still alive. Reproduction is not important for survival but for the survival of a species.
What is the importance of reproduction?The only way to ensure that the kind of species survives and keeps flourishing on the planet is through reproduction. The process by which organisms give rise to new offspring is called reproduction. It is one of the many defining characteristics of life and loving organisms.
There are some organisms that look and act exactly like their parent/parents. Whereas, other kinds of organisms share similar traits with their parents but are not completely like them. These organisms are unique individuals in their various characteristics.
Some species have two parents, whereas others have just one. It is determined by the method of reproduction by these organisms. It also determines the percent of similarity of the organism with its parents.
Reproduction is basically of two types: asexual reproduction and sexual reproduction. Asexual reproduction involves the development of new organisms by a single parent. Sexual reproduction involves two parents and their fusion of gametes.
Therefore, Reproduction is essential for the survival of a species and not for the survival of an organism.

Answers
Answer:
Birds eat plants ,such as seeds, but also eats bugs like worms, crickets, etc.
Explanation:
The seeds are plants which is a producer and bugs are primary consumers since they eat plants as well.
Birds eat plants ,such as seeds, but also eats bugs like worms, crickets, etc. The seeds are plants which is a producer and bugs are primary consumers since they eat plants as well and this is known as food chain.
What is a food chain?A food chain is a network of links in a food web that runs in a straight line from producer organisms to an top predator, detritivor, or decomposer species.
A single path of energy flow through an ecosystem can be seen in food chains. It just depicts one food source that an organism consumes, but a food web depicts numerous food sources and all possible energy flow pathways. Who eats whom is described in a food chain. All of the food chains in an ecosystem make into a food web.
Each organism in an ecosystem resides at a certain trophic level, position, or web of relationships with other organisms. The base of the trophic pyramid represents producers animals that synthesize their own food through photosynthesis or chemosynthesis.
Thus, this way, food chain and food web can be compared.

What is an Ammeter?An ammeter is an instrument which is used to measure the electric current which can be either direct current (DC) or alternating current (AC) electric current, in units of amperes (A). Ampere (A) is the SI unit of electric current.
An ammeter can measure a wide range of electric current values as at very high values only a small portion of the electric current is directed through the instrument and a shunt is placed in parallel arrangement with the meter which carries the major portion of the circuit.

B.) The central and hottest section of the sun.
C.) Layer of the sun where energy is transferred by convection.
D.) Layer of the sun that is known for its red color and can only be seen during eclipses.
Answers
Answer: The answer is the layer of the sun that radiates energy outwards from the sun core
Explanation: the reason why that is becuase the convection zone is a layers which is unstable to convection. And energy is primarily or partially transported by convection
The layer of the sun where energy is transferred by thermal conduction is the radiative zone. The central and hottest section of the earth is the core. The layer of the sun where energy is transferred by convection is the convective zone and the layer of the sun known for its red colour that can only be seen during eclipses is the chromosphere.
What is the Sun?It is the central star of our solar system around which the planets and other planetary bodies revolve. Ninety-nine per cent of the mass of the entire solar system is constituted by the sun.
The sun produces a tremendous amount of energy. A part of this energy reaches the earth. The perfect distance of the earth from the sun ensures that this energy supports life on earth.
The sun is considered to be a 'dwarf' star among the other stars studied and observed in the observable universe. The sun has been formed from the material which had been processed inside of a supernova and is present in the outer regions of our milky way galaxy. The sun is made of several layers and each has its own role.
Therefore, The layer of the sun where energy is transferred by thermal conduction is the radiative zone. The central and hottest section of the earth is the core.
