according to the theory of plate tectonics, the continents are embedded in lithospheric plates. as these plates move, they carry the continents with them. the ocean basins are part of lithospheric plates as well. identify the weakness in weneger's continental drift hypothesis.
Vascular plants are the ones that posses vascular tissue, sporophyte, and true roots, leaves, and stems.
Explanation:
The vascular plants are land plants. They form a very large group in the plant family, varying in size, shape, color etc. All of the plants in this group share some characteristics that define them as vascular plants, such as having true vascular tissue, sporophyte, and having true roots, leaves, and stems.
Another characteristic of the vascular plants is that they have lignified tissue which have the purpose of distributing the minerals and water throughout all of the plant. Plants that fall into this group are the flowering plants, conifers, ferns, clubmosses, and horsetails, and they are spread out on almost all of the plant when plant life is possible.
Answer:
Mutations in regulatory proteins during the cell cycle may cause affected cells to divide uncontrollably
Explanation:
Answer:
Endergonic.
Explanation:
Product produced by Endergonic reaction have more potential energy than reactants. Energy is required for organisms to grow because it's necessary for production of new materials. Endergonic reaction have two main purpose in biology:
1) Helping to release energy which is stored in food molecules and helping organism to survive without harvesting the energy directly comes from sunlight.
2) Helping to create building blocks of life such as DNA, RNA, and proteins created with the help of reaction which forms new bonds present between chemical building blocks. These reactions are generally endergonic reactions.
Example of endergonic reactions are:
1) DNA-RNA synthesis.
2) Protein synthesis.
3) Fatty acid synthesis.
