How does a food chain illustrate the law of conversation of energy and mass in an ecosystem
Explanation:
Conservation of Energy in Living Systems
Energy changes form as it flows through an ecosystem, but the total amount of energy in the system remains constant. Food chains show how energy flows in an ecosystem. ... The chemical energy stored in producers is passed to consumers, organisms at higher levels on the food chain.

As the zygote undergoes cleavage, the number of cells increases but the overall size of each cell gets smaller. By the time the zygote reaches the 16-cell stage, it is called a
Answer:
Morula.
Explanation:
A zygote is the product resulting from fertilization. During the journey of the zygote through the fallopian tubes, until its implantation in the uterus, it divides many times, thus going through different phases. From the 16 cells it is called a morula, this stage represents the set of cells from the division of the fertilized ovum, in the first stages of embryonic development. It represents an intermediate phase between the zygote and the blastocyst. The morula stage is characterized by the fact that the replicating cells are all the same size, and there is no differentiation of organs.

How would you describe the interior of the lungs?
Explanation:
The interior of the lungs is made up of spongy tissues containing many capillaries and around 30 million tiny sacs known as alveoli.
The alveoli are cup-shaped structures found at the end of the terminal bronchioles and surrounded by capillaries.
Answer:
It's spongy and air filled sort of.
Explanation:
The lungs are a pair of spongy, air-filled organs located on either side of the chest (thorax). The trachea (windpipe) conducts inhaled air into the lungs through its tubular branches, called bronchi. The bronchi then divide into smaller and smaller branches (bronchioles), finally becoming microscopic.
The deltoid muscle can effectively contract through its entire ROM because of the upward rotation of the scapula, which serves to maintain tension in the deltoid muscle. If the deltoid loses tension, it becomes
Answer:
Actively insufficient
Explanation:
The deltoid is a muscle attached by tendons to the bones localized on the top of the shoulder (clavicle, scapula and humerus). The amount of force generated by a multi-joint muscle decreases as the muscle moves the joints simultaneously. A multi-joint muscle becomes actively insufficient when it shortens over both joints simultaneously and it no longer has the ability to develop an effective tension. Moreover, a muscle is passively insufficient when it can't be stretched to its fullest length across multiple joints simultaneously.

Cells go through a series of events known as the cell cycle as they grow and divide. During the cell cycle, a cell grows, prepares for division, and then divides to form two daughter colls. Each daughter col then
moves into a new cell cycle of activity, growth, and division. SC.912. L. 16.14
The cell cycle includes four phases - G1 SG2, and M. What occurs during the Sphase?
A. Prepares the cell for mitosis
B..There is intense growth and activity
C.New DNA is synthesized as the chromosomes are replicated
D.Cells increase in size and synthesize now proteins and organelles
Answer:
C
Explanation:
I think it’s C because starts to replicate and yea
The cell enters the cell cycle, and each daughter cell later moves into a new cell cycle of activity, growth, and division, and in the S phase, new DNA is synthesized as the chromosomes are replicated, which is present in option C.
What is the S phase in the cell cycle?The cell cycle has different phases, and each phase is specific for a particular function, such as the G1 phase, which is the first growth phase. In the G1 phase, the growth of the cell takes place, such as the new protein synthesis, and then the cell enters the S phase, in which the DNA replicates and a copy is made.
Hence, the cell enters the cell cycle, and each daughter cell later moves into a new cell cycle of activity, growth, and division, and in the S phase, new DNA is synthesized as the chromosomes are replicated, which is present in option C.

how does energy flow in this terrarium in terms of photosynthesis and cellular respiration
Explanation:
through photosynthesis setting organs convert solar energy to chemical energy which is then used to build carbohydrate molecules .the energy used to hold this molecule together is released when an organism breaks down food .cell then use this energy to perform work known as cellular respiration
For photosynthesis, plants require carbon dioxide and sunshine. Through chemical reactions powered by chemical energy, they generate glucose and oxygen. Plants naturally create oxygen and absorb carbon dioxide.
What is photosynthesis?Both humans and animals depend on cellular respiration. They breathe in oxygen and food, which they then chemically digest and expel carbon dioxide from.
For life to continue on Earth, this cycle is necessary. Setting organs transform solar energy into chemical energy through photosynthesis, which is then utilized to create carbohydrate molecules.
When a creature breaks down food, the energy that was utilized to hold this molecule together is released. Cellular respiration is the process through which a cell uses this energy to carry out work.
Therefore, through chemical reactions powered by chemical energy, they generate glucose and oxygen.

What are the three steps of cellular respiration called?
Please list the order of organization within animals, beginning with the atom and ending with the organism. Describe each level of organization.
Answer:
Atom, molecule, cell, tissue, organ, organ system, and organism.
Explanation:
Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the body's major organizational levels.
What are the levels of organization in animals?Atoms, molecules, organelles, cells, tissues, organs, organ systems, and the human organism are the major levels of organization that may be found in the body. These levels range in complexity from the simplest to the most sophisticated.
Cellular level is key. A cell is the smallest self-replicating unit of life. All cells share a few cells, despite differences in design and capacity. Cells contain nucleic acids (DNA and RNA), cytoplasm, and a lipid-based film. Cells have organelles in their cytoplasm that perform distinct functions.
Tissues are clusters of related cells that function together. Connective tissues provide organs shape and structure. Muscle cells contract to allow movement. Epithelial tissues cover organs, skin, and the stomach. Specialized cells in nervous tissue, the spinal cord, and the brain transform information using electrochemical impulses.
Organs are structures made of tissues that perform biological activities. Organs have tissues. Organs combine tissues to perform a certain purpose. Size and complexity of organs vary tremendously. Organs include the heart, lungs, and brain. The next level, organism level, is formed of different organs to maintain the body.
