the circulatory system provides the the skeletal system with nutrients within blood and aids in keeping muscles ligaments and tendons oxygenated.
___________ is the process whereby the organism becomes larger
Organisms in the deepest part of the ocean (the abyssal zone): A: come up to the surface often to breath
B: do you not need oxygen
C: feed only on minerals
D: Live without any sunlight
Organisms in the deepest part of the ocean come up to the surface to breath.
Type of change that doesnt involve the formation of a new kind of matter
Tissues are groups of similar cells working together
Organs are created when several tissues are combined, which starts with cells. An organ is a bodily structure made up of two or more tissues that cooperate to perform a certain function.What is the function of Tissue?
The connective tissue keeps the body's organs in their proper positions and gives them structure. It serves as the body's main supporting tissue.
The following are additional crucial bodily processes for which connective tissue is crucial: Insulating. Provide support and aids in tying the organs together.
The term “connective tissue” refers to a set of tissues in the body that work together to keep the body and its organs in shape and to offer internal support.
A collection of cells with similar structures and functions is referred to as a tissue.
Therefore, tissues are groups of similar cells working together to form an organ in the body.

Purines have ____ ring(s), (each) containing _____ nitrogen(s), whereas pyrimidines have _____ ring(s), (each) containing _____ nitrogens. A) 1; 1; 1; 1
B) 1; 2; 1; 2
C) 2; 1; 1; 2
D) 2; 2; 1; 1
E) 2; 2; 1; 2
E. 2; 2; 1; 2
Purines and pyrimidines are the nitrogenous bases. They are present in nucleotides. Adenine and guanine are the purine bases. Purine bases have two rings in their structure. Each ring has two nitrogen atoms as part of the ring. On the other hand, uracil, thymine and cytosine are the pyrimidine bases. Pyrimidines have a single ring in their structure. Each ring in pyrimidines also has two nitrogen atoms as part of the ring.
Explanation: Purines are nitrogenous bases that contains a two-ring carbon structure, with Adenine and Guanine as nitrogenous bases. while pyrimidines has a one-ring carbon structure with Cytosine and Thymine as its nitrogenous base.
What can happen if an organism's population gets too big?
Teddy is explaining to his class that hydrothermal vents form isolated ecosystems. Which point should he explain? A. The organisms of the hydrothermal vent do not interact with the organisms of different ecosystem. B. The organisms of the hydrothermal vent are a part of other food webs. C. There is a continuous input and output of energy and materials in the hydrothermal vent. D. Sunlight plays a vital role in the hydrothermal vent ecosystem.
A. The organisms of the hydrothermal vent do not interact with the organisms of different ecosystem.
An hydro-thermal vent can best be described as an isolated ecosystem or a sort of closed ecosystem. Most of the organisms here do not interact with the larger ecosystem for survival and are not interdependent on them.
In an hydro-thermal vent, life here is supplied with thermal energy that originates from within the crust or the reaches of the core. Since organisms here would thrive regardless of solar radiation, they can produce a sort of localized food web within and would not associate with other ecosystem for survival.
Isolated ecosystems are therefore self-sustaining systems that would not depend on resources from other ecosystems.
Which of these would spread seeds? A
a chipmunk not touching a plant at all as it moves through the forest
a squirrel finding an acorn buried in the ground and digging it up to eat
a bird getting seeds stuck in its feathers as it moves around the woods
a plant’s leaves starting to dry up because it doesn’t have enough water
The answer is c, becuase the seeds will get caught in the birds feathers, the bird will carry the seeds and the seeds will pollinate everywhere
