I don´t know if this is right, but this is what I got.  

Explanation:

Answer:

When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.

An isometric training is a static contraction of a muscle.

Explanation:

An isometric training is a type of exercise which involves the static contraction of a muscle where no visible movement in the angle of the joint occur.

During isometric training, the muscles doesn't change its length and the affected joint doesn't move from its place.

Explanation:

A plant that produces seed cones and pollen cones is a vascular plant, and plants that produce seed cones and pollen cones belong to the group of plants known as gymnosperms.

Gymnosperms are a group of seed plants that produce seeds that are not enclosed in an ovary and produce open seeds that are usually borne in cones and include a variety of plant species, including conifers such as pine, spruce, and fir trees, cycads such as palm-like plants, ginkgoes, etc., and the production of seed cones and pollen cones is a vital characteristic of gymnosperms, these seed cones, which are also called female cones, produce seeds that are typically larger and more complex than pollen grains.

Hence, a plant that produces seed cones and pollen cones is a vascular plant and belongs to the group of plants known as gymnosperms.

Point mutation can be an insertion, substitution, deletion etc, but it is the gene mutation that would have the smallest impact on a protein's amino acid sequence. This is because the change to the genetic sequence involves a single base.
