Answer:
The correct answer would be reproduction.
Single-celled organisms usually reproduce asexually with the help of cell division.
Asexual reproduction is a type of reproduction which takes place without the fusion of gametes and hence required only one parent.
Various types of asexual reproduction are fission (binary or multiple), budding, fragmentation, vegetative propagation etc.
Unicellular organism usually divide by fission either binary or multiple.
In binary fission, a parent cell divide into two equal sized daughter cells such as observed in bacteria.
In multiple fission, a parent cell divides into multiple daughter cells as observed in multiple fission of sporozoans etc. During this, parental nucleus divides several times with the help of mitosis without cytokinesis which produces several nuclei within a parent cell. The cytokinesis then takes place which results in separation and production of multiple daughter cells.
Answer: due to insufficient exocytosis in the type II alveolar cells
<span>The two basic molds are: Expendable
mold and permanent mold. </span>
Molding is a
process where a rigid frame (mold) is being used to manufacture by shaping liquid
or pliable raw materials. However, molding is synonymous to casting; casting is
a process where a liquid metal is delivered into a mold which contains a hollow
cavity of the intended shape.
Expendable mold casting can be classify as
sand, plastics, plaster which make use of non-reusable or temporary molds while Permanent mold casting is a metal
casting process that use reusable molds.
<h2>Answer:</h2>
The correct answer is option D which is bones provide structure and support to the body, while muscles move the bones.
<h3>
Explanation:</h3>
- The muscles are composed of muscle cells, 3 layers of connective tissues are also associated with muscles.
- Muscles are soft tissues of body which have ability to contract and relax.
- Bones are hard tissues composed of collagen fibers and inorganic minerals. Muscles are attached with bones. Due to hard structure, bones provides support and structure to body. While muscles are attached with bones, and their contraction and relaxation is the cause of movement
