The correct answers are B. They do not have natural predators to regulate their population growth and E. They compete with native organisms for resources.
Explanation:
Nonnative species include any species that does not belong to an ecosystem but was introduced to it. Nonnative species are considered are an important threat to biodiversity and native species because they usually disrupt the natural equilibrium in the ecosystem.
This usually occurs because nonnative species population grow rapidly due to the lack of natural predators; for example, Asian carps which are native from Asia and were taken to the U.S. are eaten by other fish and animals in their native ecosystem, but once they are introduced in another ecosystem their population increases due to lack of predators. Additionally, nonnative species often compete with native species for resources, this also happens with the Asian carp that competes for food such as snails or mussels with native species in the U.S.
Answer:
Epimysium
Explanation:
The muscle fibers of a skeletal muscle are surrounded by three layers of connective tissues to form a muscle. The three layers of connective tissues are –
a) Endomysium – It is the inner most layer of connective tissue that surrounds all the muscle fiber
b) Perimysium – This layer lies above the endomysium and forms a fascicle
c) Epimysium – This is the outermost layer of the connective tissue surrounding the skeletal muscle. Epimysium form a complete muscle by encircling the fascicle
Answer : Option B) Cell theory has been unchanged for many decades and as a result can be accepted as fact.
Explanation : As cells are basic units of life and all the living beings are made up of cells, this was correctly defined by the cell theory. This theory is since its discovery not changed for many decades and is widely accepted as a fact too.
Answer:
C reproductive cells ( sex cells)
Answer:
A) Tissue
Explanation:
Cells are the basic and fundamental units of all living organisms. Plants, like every other multicellular living organisms, are composed of cells that perform different functions. A group of cells that perform similar functions make up or form TISSUES, tissues that work together form the ORGAN, organs that work together to perform same function form the ORGAN SYSTEM.
In plants, sieve tubes and companion cells work together to carry out a similar task in plants, which is to transport nutrients and sugar inside the plant. Since sieve tubes and companion cells work together to fulfil same task, they collectively form a tissue in plants called PHLOEM tissue.
