Answer:
Because ferns and fern allies posses true vascular tissues, they can grow to be much larger and thicker than the bryophytes.
Bryophytes mark the transition to land and the origin of vascular plants, and hence, link the seed and vascular plants to their algal ancestors.
Molecular phylogenetic studies conclude that bryophytes are the earliest diverging lineages of the extant land plants. They provide insights into the migration of plants from aquatic environments to land.What is evolution trends?Evolutionary trends, whether macro evolutionary events across higher taxa and large spans of geologic time, or more circumscribed events within smaller clades, have long played a prominent role in evolutionary theory.
The identification of trends in the history of life has been used as evidence for the increasing adaptions of life, for evolutionary progress, and more recently as support for selection at multiple levels.To know more about evolution here

Read the description of interphase at the bottom of the gizmo. What happens to the cell at the beginning of interphase?
Answer:
During the G1 phase, cells synthesize and grow mRNA and proteins for DNA synthesis.
Explanation:
Interphase is the resting phase of cell cycle. In this phase cell grows in size, accumulate nutrients and duplicate its genome. It also take part in mRNA and protein synthesis.
What are steps involved in cell cycle?Cell cycle is the series of events in which cell grows and duplicate to form daughter cells.
It has two phases:
Interphase: in this phase cell synthesize, grow, produce mRNA and protein and replicate cell's DNA. It is divided into: G1, S and G2 phase.M-phase: in this phase actual cell division takes place.Thus, in the beginning of interphase, cells prepare for division, accumulate nutrients and duplicate their genome.

ROVs (remotely operated vehicles) have become quite valuable in exploring the ocean floor, particularly the trenches. Therefore, the correct statement is option C. The other two statements are true and false, respectively.
What are the uses of ROVs?ROVs are used in marine science to explore and gather data from areas that are too deep or dangerous for human divers to access. ROVs are of great importance in the ocean floor, particularly the trenches. These are type of vehicles which are controlled remotely and well equipped with cameras and sensors which gather information from the deep sea environment.
Marine science is a complex and interdisciplinary field that requires a strong foundation in scientific principles and research methodology. An advanced degree, such as a master's or doctorate degrees are required in this field because certain skills are used to conduct research in this field, such as ability to design and execute experiments, etc.
it is very difficult for a marine biologist to get a job because it involves working with large marine animals and are highly competitive jobs. Marine biologists involve various areas such as marine conservation, marine ecology, or marine biotechnology.

Record the elements present in each unknown astronomical object. Be sure to indicate “yes” or “no” for each element.
Hydrogen Helium Lithium Sodium Carbon Nitrogen
Moon One
Moon Two
Planet One
Planet Two
We record the elements present in each unknown astronomical object according to metallicity.
Moon one - HeliumMoon two - SodiumPlanet one - Hydrogen -Carbon Planet two - Lithium - Nitrogen
To understand these answers, we need to know what metallicity.
What is metallicity?In astronomy and physical cosmology, metallicity (also called Z) of an object is the proportion of its matter made up of chemical elements other than hydrogen and helium. Because stars, which make up most of the visible matter in the universe, are composed primarily of hydrogen and helium, astronomers conveniently use the generic term "metal" to describe all other elements collectively.
With this information, we can conclude that we have recorded the elements present in each unknown astronomical object according to metallicity.

Based on your knowledge of protein synthesis and the information in the diagram,
summarize how enzymes are made. (3 points)
Explanation:
The chemical reactions involved in photosynthesis are controlled by enzymes . As with any other enzyme-controlled reaction, the rate of photosynthesis is affected by temperature. At low temperatures, the rate of photosynthesis is limited by the number of collisions between enzymes and substrate.
Enzymes are biological catalysts - they speed up chemical reactions. The reactions of photosynthesis, and many other biological processes, are controlled by enzymes.
Enzymes are required for most of the chemical reactions that occur in organisms. These reactions occur in the breakdown of chemical molecules, which we see in the digestive system.
