Answer:
Identical twins came from the same sperm and egg, so they have the same chromosomes and genes. So identical twins with identical DNA may have different genes turned on, causing them to look and act differently, and even to develop different diseases such as cancer.
Explanation:
Answer:
B. The amounts of sun, water, and
nutrients affect the growth of a plant
Explanation:
Gene expression is the way by which the genes of an organism instructs the production of proteins, which are responsible for the organism's phenotype. However, the trait or characteristics possessed by organisms are not strictly or 100% dependent on the genotypic factors but also on the environmental factors.
Environmental factors are the biotic (living) and abiotic (non-living) factors that affect organisms development and growth. An example is how the amount of sun, water, and nutrients, which are all environmental factors, affect the growth of a plant. Growth in plant, therefore, affects gene expression.
Answer;
Seedless plant.
The fossil of a plant reveals that it produced spores that were used for reproduction. It was a seedless plant.
Explanation;
-Seedless vascular plants are plants such as fern and horsetails, liverworts, mosses; which contain vascular tissues, but do not produce flowers or seed.
-These plants reproduce using haploid , unicellular spores instead of seeds.
-These plants have life cycles with two distinct stages; one in which spores are produced and one in which sex cells are produced.
During Physical Change there would be a re-arrangements of atoms or molecules, changes of the arrangement may be change in the distance between atoms or molecules, change in the crystal form.
Good luck!
