D) Stems
Answer:
D) Stems
Explanation:
Stems are a part of a plant that are responsible for various things. Their main responsibility is to support the plant, this is through holding up the leaves, flower, and buds. Stems also take nutrients and water from the roots in the ground and transport that up the stem and into the other parts of the plant. Lastly, leaves grow out of the stem, so it is responsible for that as well.

Why does social science intersect with marine science?
A. Many poems and novels are written about the ocean.
B. Human behavior causes a lot of issues with the ocean.
C. Social science is another important branch of the sciences.
D. These are very different disciplines that have little connection.
Answer:
it's either b or d I think
Social science intersects with marine science because human behavior causes a lot of issues with the ocean.The correct option is B.
The ocean is a body of salt water that covers approximately 70.8% of the Earth and contains 97% of Earth's water, making Earth an ocean world. The term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided.Distinct names are used to identify five different areas of the ocean: Pacific , Atlantic, Indian, Southern, and Arctic.
Seawater covers approximately 361,000,000 km² of the planet. The ocean is the primary component of the Earth's hydrosphere, and thus essential to life on Earth. The ocean influences climate and weather patterns, the carbon cycle, and the water cycle by acting as a huge heat reservoir.Pollution of water by human activities makes the marine science intersect with social science.
Thus, option B is correct.

How did the first small organic molecules form in earth’s earliest atmosphere? There are two main theories discussed. Make sure you know both. Refer to Miller and Urey experiment and meteorite theory
zapped gas/liquid into amino acids
many amino acids thought to have come from meteorites
a mixture of gases and water that Miller thought were present on early Earth was heated and zapped with electricity to mimic lightning. This created five identifiable amino acids
newscientistcom
We know amino acids exist in some kinds of meteorites and interplanetary dust
Many left-handed amino acids were found inside the Murchison meteorite. Most were kinds not found on Earth.
92 different amino acids have been identified in the Murchison meteorite. Of these, only 19 are also found on Earth. The remaining amino acids have no apparent terrestrial source. This discovery led scientists to consider the possibility that Earth's life forms originated elsewhere in the universe. And the same cosmic process that may have helped life arise on Earth could also be seeding life elsewhere in the universe

The organization of a organism from smallest to largest is Cell, tissue, organ, organ system, organism
True
False
The cellular organization from smallest to largest is cells, tissues, organ, organ system and organism. Hence, the given order is true.
What is cellular organization ?Cellular organization refers to the hierarchical arrangement of cells in living organisms. All living organisms are composed of one or more cells, and the way in which cells are organized within an organism is critical to its overall function and survival.
At the smallest level, cells are organized into organelles, which are specialized structures within the cell that perform specific functions. For example, mitochondria are organelles that produce energy for the cell.
Cells are then organized into tissues, which are groups of cells that work together to perform a specific function. Examples of tissues include muscle tissue, which is responsible for movement, and nerve tissue, which is responsible for transmitting signals throughout the body.
Tissues are then organized into organs, which are structures that are made up of two or more different tissues and perform a specific function. For example, the heart is an organ that is made up of muscle tissue and nerve tissue and is responsible for pumping blood throughout the body.
Finally, organs are organized into organ systems, which are groups of organs that work together to perform a specific function. For example, the circulatory system is an organ system that includes the heart, blood vessels, and blood and is responsible for transporting oxygen and nutrients throughout the body.

respiration
Ophotosynthesis
Answer:
cellular respiration...that's breathing out of humans
and through human activities like burning of fossil fuels...
The respiration process adds carbon dioxide to the air. Therefore, option "C" is correct.
What is respiration?A metabolic process known as respiration involves an organism's living cells taking in oxygen and releasing carbon dioxide from the oxidation of complex organic substances to obtain energy (ATP). High-impact breath happens in the mitochondria and requires oxygen and glucose, and produces carbon dioxide, water, and energy. The synthetic condition is C6H12O6 + 6O2 → 6CO2 + 6H2O.
There are two types of respiration that occur in nature that is aerobic respiration and anaerobic respiration. Aerobic respiration involves the use of oxygen for oxidation and later oxygen is not used.
Therefore, respiration is the cellular process that happens in all organisms.
