Answer:
phytoplankton
Explanation:
they are the base of the food web, without them other large organisms will die.
There would be no ocean life without phytoplankton, hence option 2 is correct.
What is phytoplankton?Without plankton, the bigger creatures in the marine food web would likely perish. Millions of people would be hungry if there were no plankton or fish.
Millions, if not billions, of people, would be hungry if the oceans were to disappear. The foundation of the food chain and the basis of all ocean life is phytoplankton.
Fish and other big creatures eat phytoplanktons, which also provide them with energy. They depend on light or the sun to survive.
Without it, we'd be lost, but we hardly even notice it. The small plants and creatures that live in our seas, lakes, and ponds, known as plankton, are essential to the existence of the earth.
Therefore, the food chain and the basis of all ocean life are phytoplankton.

Scientists believe there are several basic requirements needed for life to exist on a planet. These include the
presence of liquid water and a source of energy, What characteristic of Earth allows water to exist as a liquid?
Answer: Liquid water is an essential requirement for life on Earth because it functions as a solvent. It is capable of dissolving substances and enabling key chemical reactions in animal, plant and microbial cells. Its chemical and physical properties allow it to dissolve more substances than most other liquids.
Explanation:
Liquid water and carbon, as well as a source of energy, are essential for life to emerge and develop.

Explain how the boiling of water and the cooling of water vapor is a reversible reaction.
(think about hydrogen bonds between water molecules)
Answer: This is a reversible reaction because you can boil the water to make water vapor and when the water vapor is cooled down, it ill turn back into its original liquid, water. This occurs because of hydrogen bonding between water molecules.

Impressions of tropical swamp plants were observed on rocks in polar regions. The impressions were dark black imprints, which means the fossils are examples of . The fossils tell us that polar regions .
Answer:
the fossils are examples of... mineralization
The fossils tell us that polar regions... formed a supercontinent that divided and slowly drifted to polar regions
Explanation:
Mineralization is a type of fossilization where rich-mineralized water fills the pores of the dead tissues for a long time. Subsequently, when this water is evaporated, the excess of minerals is deposited on the tissues, thereby mineralizing organic tissues.
Fossils enable us to understand more accurately past climatic conditions from regions where these fossils were found. For example, the discovery of plant fossils closely related to tropical species in polar regions suggests that these regions were once a part of a super landmass known as Pangea that divided and drifted a long time ago (millions of years ago).

the fossils are examples of... mineralization

Answer:
Substrate inhibitor, activator or a neurotransmitter.
Explanation:
The original ligand was most likely a substrate inhibitor, activator or a neurotransmitter. A ligand is a small molecule that is able to bind to proteins by weak attractive forces such as ionic bond and hydrogen bonds etc. It also transmit signals in the process from one part to another part. It also act as inhibitor and activator of reactions in the process.

The concept of a transgene has been broadly understood for more than 100 years, as the advent of genetic research made its way into the 20th century. As time went by, technologies evolved, and transgenes became widely used during the late 1970s and early '80s. Which is one reason scientists produce transgenic organisms?
A) to create new species of organisms
B) to control microorganisms in the soil
C) to treat certain types of diseases
D) to prevent habitats from being destroyed
Answer:
C) To treat certain types of diseases
Explanation:
Scientists produce transgenic organisms to treat certain types of diseases. Hence, option C is correct.
What are transgenic organisms?An organism or cell is referred to as transgenic if its genome has been transformed by the intentional introduction of one or more foreign DNA sequences from another species. In the lab, transgenic organisms are created for scientific investigation. GMOs, or genetically modified organisms, are another name for transgenic organisms (GMOs).
Transgenesis enables the enhancement of the amount, overall quality, and particular nutritional composition of nutrients in animal products. Transgenic technologies might make it possible to increase or transmit features that are good for nutrition.
Scientists produce transgenic organisms to treat certain types of diseases. Hence, option C is correct.

Which factor is most important for classifying two species into the same group?
A. They have a common ancestor.
B. They have similar common names.
C. They live in the same type of environment.
D. They look very similar to each other.
They have a common ancestor. Therefore, option (A) is correct.
What does it mean to have common ancestor?Having a common ancestor means that two species share a lineage and have a common parent species from which they both evolved. This common parent species may have existed many generations ago, but its descendants, including the two species in question, still retain a genetic relationship.
The concept of a common ancestor is a fundamental principle in evolutionary biology, as it provides evidence for the theory of evolution and helps to explain the diversity of life on Earth. The study of relationships among species and the determination of common ancestry is known as phylogenetics.

the relationships between cells and other levels of organization in biological systems and to the
whole biological system.
Answer:
In biological system, cell is known as the basic unit of all organisms. Unicellular organism consist of one cell only but that single cell helps them to perform all the functional activity.
Levels of organization in biological systems is defined as the hierarchy of several components from smallest to complex in biological system.
Cell is one of the important part of Levels of organization in biological systems, as in multicellular organisms group of cells form tissue that create an organ and many organs together form organ system within an organism. The cell is basic unit in all organisms and without a cell, an organism can not develop.
The group of these organism formed from a small cell then form complex component of Levels of organization such as population, community, ecosystem and Biosphere (in sequential order).
