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).
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

Answer:
cellular respiration and aerobic respiration
Explanation:
Explain why if you lightly place a paper clip in water it floats, but if you
disturb the water it sinks.
The paper clip, which has a far higher density than the water, can float because of the strong surface tension.
What is the surface tension of liquid?Because water is polar, its molecules are attracted to one another. Water “sticks” together due to the hydrogen ends, which are positive compared to the oxygen ends, which are negative.
Because of this, there is surface tension, and breaking these intermolecular interactions requires a certain amount of energy.
Whether an object will float or sink in another substance depends on its density. If an object's density is lower than the liquid it is placed in, it will float. If an object is heavier than the liquid it is immersed in, it will sink.
Therefore, if you lightly place a paper clip in water it floats, but if you
disturb the water, it sinks.

Which are classified as sac fungi?
O truffles, morels, yeast
O mushrooms, puffballs, rusts
O morels, mushrooms, chytrids
O chytrids, truffles, puffballs
Truffles, morels, yeast are classified as sac fungi. So, the correct option is (A).
What is Sac fungi?Ascomycota also known as sac fungi, belong to a group of fungi (Kingdom Fungi) characterized by a saccular structure, the ascus, which contains four to eight ascospores in the sexual stage.
These are divided into subgroups based on whether the asci are produced singly or in one of several types of fruiting structures, or ascocarps, and on the method of discharge of the ascospores.
Many ascomycetes are plant pathogens, while some are animal pathogens, where some are edible mushrooms, and many live on dead organic matter. The largest and most commonly known ascomycetes include morels and truffles.
Thus, truffles, morels, yeast are classified as sac fungi. So, the correct option is (A).

The Phoenix area of the Southwestern desert typically receives 8 inches of precipitation yearly, in two seasonal patterns. Even though it is an arid region, it has high biological diversity. Thin-leaf trees abound, such as palo verde and desert ironwoods wildlife includes insects, reptiles, many bird species, small rodents, and other mammals. Which factor in the Southwestern desert ecosystem is abiotic?
A rainstorm can be considered an element in the Southwestern desert ecosystem that is abiotic.
What is an abiotic factor?An abiotic factor is any type of non-living condition that interacts with organisms (biotic factors) in an ecosystem.
Some examples of abiotic factors may include rainstorms (precipitations), temperature, light conditions, etc.The range of abiotic factors is a fundamental issue for the survival of organisms that live in an ecosystem.In conclusion, a rainstorm can be considered an element in the Southwestern desert ecosystem that is abiotic.

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.

Do homologous structures have the same function in different organisms?
Answer:
The term “homologous structures” refers specifically to similar structures found in different species that have a common ancestry or developmental origin. Note that homologous structures don’t have to perform the same function in a species, the only requirement is that they are similar in form and exist in species with common ancestry.
Explanation:
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.
