Which statement correctly describes the relationship between air temperature and air pressure?
1. Warm air rises, creating an area of low pressure.
2. Cool air sinks, creating an area of low pressure.
3. Warm air sinks, creating an area of low pressure
4. Cool air rises creating an area of low pressure.
Answer:
jayfeather friend me
Explanation:
Temperature refers to how warm or cold air is, and the density of the air is how many molecules are packed into a certain space of air. Air pressure is influenced by temperature because, as the air is warmed, the molecules start moving around more, so they bump into each other more often and create more pressure.

In addition to all being autotrophs, what important feature do all three plants share?
A)
seeds
B)
flowers
C)
xylem and phloem
D)
seeds in ovaries
Answer:
C)
xylem and phloem
Explanation:
The three plants in the picture are all vascular plants. Vascular plants have dedicated tissues that aid the transportation of food and water. They have a root, shot, and the vascular system itself. The two main types of vascular tissues are the xylem and the phloem.
The xylem is used in the transportation and storage of the water-soluble nutrients. The phloem transports organic molecules such as the different types of sugars and proteins to the cells that require them in vascular plants.

Explanation:
A cell is simply defined as the structural and functional unit of an organism. It is made up of highly organized physical structures called intracellular organelles. These organelles includes:
• Ribosome
• Lysosomes
• Smooth Endoplasmic reticulum
• Plasma membrane
A type of cellular motion called ciliary movement, is a whip-like movement of CILIA on the surface of cells takes place in the respiratory airways of human.
The cytoplasm is filled with both intracellular fluid and organelles while the cytosol contains mainly dissolved proteins, electrolyte and glucose ( intracellular fluid).

What is Microscope?Microscope: a device that magnifies small objects, giving the user a close-up view of minuscule structures at a scale suitable for observation and analysis.
Even though optical microscopes are the focus of this article, an image can also be magnified by a variety of different wave types, such as acoustic, X-ray, or electron beams, and is then captured using direct or digital imaging, or a combination of these techniques.
The magnifying power of a microscope is a dimensionless ratio that expresses how often the thing under examination seems to be magnified.
Therefore, All organisms come from pre-existing cells that divide.

Answer: water, and oxygen
Explanation: Homeostasis depends on maintaining correct fluid levels within the cell and on exchanging useable materials, such as oxygen, for waste products, such as carbon dioxide. Plasma membranes allow water, oxygen and carbon dioxide to pass through by osmosis, or passive diffusion.

A commercial fish farm claims that each of its tanks used for growing fish is a “complete ecosystem that produces no biological waste.” Does this claim imply that the tanks contain which of the following?
A. decomposers
B. fish predators
C. at least four trophic levels
D. a diverse variety of species
Answer:
ff
Explanation:
ff
The claim that each of the fish farm tanks is a "complete ecosystem that produces no biological waste" does not imply that the tanks contain decomposers, fish predators, at least four trophic levels, or a diverse variety of species.
Why Decomposers are essential components?Decomposers are essential components of any ecosystem, as they break down dead organic matter and recycle nutrients back into the ecosystem.
The claim that the tanks produce no biological waste suggests that the waste products of the fish and other organisms are somehow being recycled within the tank, but it does not necessarily imply the presence of decomposers.
Fish predators are not necessary components of a fish farming system, as the purpose of the tanks is to raise fish rather than to provide a natural ecosystem.
Having at least four trophic levels and a diverse variety of species are both characteristics of a complex and diverse ecosystem, but they are not essential for a fish farming system to be successful.
Overall, the claim made by the fish farm is likely based on their use of technologies such as recirculating aquaculture systems, which aim to minimize or eliminate the waste produced by fish farming operations, rather than on the creation of a self-sustaining ecosystem.

Which of the following describes methyl jasmonate?
a gas emitted by cabbage plants when injured
a byproduct of the process of photosynthesis
a mycorrhizal fungus
an element of the phloem
Answer:
The correct answer is - a gas emitted by cabbage plants when injured.
Explanation:
Methyl jasmonate is a gas that is released or emitted by the leaves of the injured cabbage or when any insects eat it. It is an organic compound used as a defense mechanism by plants such as cabbage.
It is a very volatile organic compound. It is also found in flowers of Jasminum grandiflorum. It plays role in other pathways such as root growth, flowering, and fruit ripening and others.

What are 4 different protists and what makes them special
Answer:
Amoebalike protists, flagellates, ciliates, and spore-forming protists.
Explanation:
Protists are eukaryotes, which means their cells have a nucleus and other membrane-bound organelles. Most, but not all, protists are single-celled. Other than these features, they have very little in common. You can think about protists as all eukaryotic organisms that are neither animals, nor plants, nor fungi.
