D) Phosphorus cycle
E) Water cycle
All living organisms are composed of microscopic building blocks called cells, which are the structural and functional unit of life because this cell has many organelles and genetic materials that carry out different cellular functions.
The cell is the structural and functional unit of life, and it is microscopic in size. Cells join together to form tissue, and tissue joins together to form organs, which perform various functions in the multicellular organism.
The cell contains organelles such as the nucleus, which contains genetic components such as DNA. Genes that encode genetic information are present on the DNA, and depending on the gene, the cell does its function. The cell regulates both unicellular and multicellular organisms, maintains homeostasis, performs different functions, etc.
Hence, all living organisms are composed of microscopic building blocks called cells, which are the structural and functional units of life and consist of geneticmaterials.

b.temperatures in grasslands vary more
c.rainfall is low in grasslands
d.the amount of solar energy is high in grasslands?
B.linear graph with inconsistent
C.S-shaped curve with logistic growth
The correct answer is option C
The population of rabbits in an area will keep on growing until the predators (a group of foxes) reach that place.
The habitat was suitable for rabbits and they were growing in large numbers. When the foxes have arrived in the habitat of the rabbits they will eat the rabbits and their population will decrease.
This will represent the S-shaped curve with logistic growth. In this case the per capita growth of the population gets smaller as the population size increases and reaches the maximum which is limited due to resources which is known as the carrying capacity of the earth.
B. Internal respiration occurs.
C. Ribs and diaphragm muscles contract.
D. Inspiration occurs.
Answer:
The correct answer is option A.
Explanation:
Breathing is the exchange of air through the involved passages in between the atmosphere and the lungs. Inspiration is a process where we take air into the lungs from the atmosphere also known as inhalation.
Expiration is releasing air out of the lungs to the atmosphere. In expiration, the diaphragm relaxation and elastic recoil of tissue decrease the thoracic volume of lungs. That results in an increase the intraalveolar pressure in the lungs.
Thus, the correct answer is option A.
Butterfly
Tadpole
Starfish
Answer: The correct answer is- Starfish.
Radial symmetry depicts a body plan of an organism, which can be divided into two equal halves when a plane from any angle passes through central axis of the body.
Starfish is radially symmetrical organism as any plane can divide its body into two equal halves.
On the contrary, flatworm, butterfly, and tadpole show bilateral symmetry ( only single axis/ plane can divide the body into two equal halves.
Among the listed organisms, only the starfish exhibits radial symmetry, which refers to an organism's body being shaped like a pie or barrel, allowing it to be divided into more than five symmetrical parts around a central axis.
Out of the provided organisms - Flatworm, Butterfly, Tadpole, and Starfish - the type that shows radial symmetry is the Starfish.
Radial symmetry refers to when an organism has a body shaped like a pie or barrel. This means it can be divided into five or more identical and symmetrical parts.
Body parts are positioned around a central axis, much like slices of a pie.
Think of a starfish with its arms extending out from the center - each arm is effectively a mirror image of the others, thus demonstrating radial symmetry.
