What is involved in muscle contraction in larger organisms?
Muscle contraction in larger organisms involves the sliding of actin and myosin filaments in muscle cells, which is triggered by the binding of calcium ions to regulatory proteins. This process leads to the overlap of filaments and shortening of the muscle, producing movement. Nerve impulses stimulate the release of calcium ions and initiate the contraction process in response to a signal from the nervous system.
What organism contain no specialized cells?
Organisms such as bacteria do not contain specialized cells. They are prokaryotic organisms with cells that lack membrane-bound organelles and specialized structures like a nucleus.
Are cells highly organized tiny structures?
Yes, cells are highly organized structures that contain various organelles carrying out specific functions. These organelles work together to enable the cell to perform activities necessary for survival and function. This organization is critical for the proper functioning of all living organisms.
What are organisms made of many individual permanetly associated cells that coordinate their activities?
Organisms made of many individual permanently associated cells that coordinate their activities are called multicellular organisms. These cells work together to carry out specific functions, such as growth, reproduction, and response to the environment. Examples include animals, plants, and fungi.
Is a fungi bigger than a protist?
Fungi can be larger than protists because fungi are multicellular organisms, while some protists are single-celled organisms. Fungi can form complex structures like mushrooms and molds, which can be larger than individual protist cells.
What is involved in muscle contraction in larger contractions?
Microfilaments are involved in muscle contraction in larger organisms. These are small rod like structures within the cytoplasm of many eukaryotic cells.
What structures can perform all the activities required for life?
Cells are the smallest structures that can perform all the activities required for life. They contain the necessary components such as DNA, cytoplasm, and organelles to carry out functions like metabolism, growth, and reproduction.
How are multicellular organisms more efficient than unicellular organisms?
it is...... the thing that is on the moon
These organisms carry out the activities needed to maintain homeostasis by using specialized internal?
These organisms are likely referring to cells. Cells use specialized organelles like mitochondria for energy production and the endoplasmic reticulum for protein synthesis to carry out the activities needed to maintain homeostasis. Specialized internal structures allow cells to perform specific functions efficiently.

Do cells get bigger if in a bigger organizem?
Generally not. A larger organisms simply has more cells
Are cells organisms, or are they simply the building blocks of larger living organisms?
Cells are the basic units of life and the building blocks of larger living organisms. They are not considered organisms themselves, but rather the fundamental components that make up all living things.
How do organisms with many cells grow?
The number of cells gets larger, and the organism gets bigger
How many organisms with cells grow?
The number of cells gets larger, and the organism gets bigger
What organism contain no specialized cells?
Organisms such as bacteria do not contain specialized cells. They are prokaryotic organisms with cells that lack membrane-bound organelles and specialized structures like a nucleus.
Are rod shaped structures found in nucleus of every cells in an organisms?
Chromosomes (however, prokaryotic cells do not have a nucleus).
Are cells highly organized tiny structures?
Yes, cells are highly organized structures that contain various organelles carrying out specific functions. These organelles work together to enable the cell to perform activities necessary for survival and function. This organization is critical for the proper functioning of all living organisms.
