Vern and his sister Ella were given permission to use one area of their backyard garden to plant a few plants of their own. They want to plant angiosperms that will grow back next year. Which key words should they look for on the seed packets?
Answer:
The key term Vern and his sister Ella should look for on the seed packets are either "Sowing Indoors"; "Start Indoors"; "Direct Sow"; or "Sowing Outdoors".
These terms help to understand the best time to begin growing the seeds and whether they are outdoor or indoor plants.
If a seed packet has the term "direct sow after danger of frost" it means the seed should be planted outside only (if there is no starting date given).

Describe organisms that are able to produce enough energy for life processes with no oxygen available.
Answer:
Plants
Explanation:
Plants turn carbon into oxygen....
Organisms that are able to produce enough energy for life processes with no oxygen available are - prokaryotic organisms such as some bacteria and archaea and eukaryotic organisms such as yeast and lactic acid formation in mammals.
Oxygen is essential for most of the time in the production of energy However, many organisms carry out metabolism without oxygen, or can switch from aerobic to anaerobic cell respiration when oxygen is absent.
Fermentation is a process that uses an organic molecule to regenerate NAD+ from NADHAnaerobic cellular respiration is a process that uses either inorganic molecules or organic molecules to accept electrons.prokaryotes use anaerobic respiration. For example, the group of archaea called methanogens reduces carbon dioxide to methane to oxidize NADH.Thus, the correct answer is - prokaryotic organisms and some eukaryotic organisms.

A dehydrated person enters the hospital. The traditional procedure to treat a dehydrated patient is to add saline (salt) solution to their blood. Saline solution is a mixture of salt (solute) and water. However, the nurse accidentally gives the patient distilled (pure) water. What will happen to the person's cells?
Answer:
The cells will taking-in water and hemolyse
Explanation:
If water is given to dehydrated patients instead of a saline solution, the cells of the patients will take-in water from the surrounding solution by osmosis because distilled water is hypotonic to the red blood cells. The cytosol has a higher concentration of solutes than distilled water. When this happens, the cells become turgid and burst out its contents, a condition known as hemolysis.

How does heat transfer between the atmosphere and the ocean affect regional climate?
Explanation:
Both the ocean and the atmosphere transport roughly equal amounts of heat from Earth's equatorial regions - which are intensely heated by the Sun - toward the icy poles, which receive relatively little solar radiation.
The ocean and atmosphere are constantly in a process of energy exchange (heat transfer) as the ocean bodies serves as heat trap which absorbs the larger portion of the Sun's radiation, which is distributed to surrounding areas as sunlight subsides, with the ocean water also losing moisture due to evaporation.
Areas very close to the ocean, topical regions experience the highest level of evaporation and they inturn experience the highest amount of Rainfall. Hence, dictating the regional climate of the tropics.
Ocean currents also play a major role in ensuring distribution of heat, precipitation and warmth between the equatorial and tropical regions, Hence, patching a sort of balance in regional distribution of heat and Rainfall.

Answer:
Why the gravitational force continuously pulls each planet towards the Sun
Explanation:
According to Sir Isaac Newton's first law of motion, there is a gravitational force that acts on two objects or planets which always pull it towards the center of the orbit or sun . For example if there is a force that pull the Earth toward the sun, there must be equal and opposite force that also pull the sun towards the Earth.

The factor in the Southwestern desert ecosystem that is abiotic is precipitation.
What are abiotic factors?Abiotic factors are the non-living components of an ecosystem influencing the living organisms' distribution in an area. Precipitation is an abiotic factor that provides water for plants and animals to survive and is a very important part of the ecosystem.
In the Southwestern desert ecosystem, the low precipitation levels resulted in an arid environment which results in the presence of a unique array of plant and animal species that have adapted to survive in these conditions.
Temperature is also another important abiotic factor in the Southwestern desert ecosystem. The high temperatures during the day and low temperature at night influence the behavior and survival of the animals and plants that live in this environment. Wind patterns, soil type, sunlight, etc. are other abiotic factors.
Therefore, the factor in the Southwestern desert ecosystem that is abiotic is precipitation.

What is the function of the valves within the heart and veins? to ensure the production of blood within the body to ensure coordination of the heart cells for pumping blood to ensure that foreign materials do not enter the heart to ensure that blood flows in one direction only
Answer:
to ensure that blood flows in one direction only
Explanation:
Here, we want to select which of the options is the function of valves within hearts and veins.
Basically, valves serve as control mechanisms in the circulatory system.
By control, it means that they actually dictate the direction in which the blood will flow.
Hence, valves ensures that blood types which is supposed to flow from the heart does not flow towards it and blood types that are meant to flow towards it does not flow away from it
An example of this can be seen in the case of oxygenated and deoxygenated blood.
Both have different flow mechanisms which are controlled by the actions of the valves
Answer:
D. To ensure that blood flows in only one direction
