According to the information, we have to draw two branches from Cephalopoda to classificate new orders. Also, we have to draw one branch from each order to mention their common names.
How to organizate the information?
To organizate the information in a good way, we have to identify the brach of Mollusks and then, we have to understand how is the organization of each classification.
We have to follow the instructions, so we have to draw three branches from Mollusks to classificate Cephalopoda, Gastropoda and Bivalve. Once we did that, we must to draw two branches from Cephalopoda to classificate new orders (Octopoda and Teuthida). Finally, we have to draw one branch from each one to mention their common names.

Which of the following events would decrease competition for resources in an ecosystem?
A- a fire has killed off a portion of the vegetation
B- a drought reduces the amount of water available to an ecosystem
C- a disease reduces the population of rabbits in a grassland area
D- many offspring are produced in a single year
Answer:
C. A disease reduces the population of rabbits in a grassland area
Explanation:
If a disease reduces the size of a rabbit population, there will be a decreased amount of competition for resources.
Less rabbits means that there will be less competition, since there will be more food available.
For example, there would be less competition in a rabbit population of 10 rabbits compared to one of 20 rabbits. This is because there are less rabbits competing for food.
So, the correct answer is C. A disease reduces the population of rabbits in a grassland area
The events that would bring decrease competition for resources in an ecosystem is C. A disease reduces the population of rabbits in a grassland area.
What is an an ecosystem?An ecosystem can be regarded as geographic area, consisting of organism as well as weather.
There is usually competition in an eco system for food and other resources however, disease can reduces the population which in turn reduces completion.

formation of this landform? sc.6.E.6.1
wind
water

According to the given statement wind is probably most responsible for the formation of this landform.
What is Land formations?The four main categories of landforms are plains, plateaus, hills, and mountains. Landforms include things like rivers, lakes, buttes, canyons, basins, and valleys.
An earthly feature that is a part of the terrain is referred to as a landform. There are four main categories of landforms: mountains, hills, plateaus, and plains. Valleys, buttes, canyons, and basins are examples of minor landforms.
Mountains and hills can be pushed up by the Earth's tectonic plate movement. Valleys and canyons can be formed by erosion brought on by water and wind. The duration of these procedures can reach millions of years.
Underwater mountain ranges and seabed basins are examples of landforms that can exist. In the South Pacific lies the Mariana Trench, the world's deepest landform.

The technology in the picture produces which energy conversion?
Quo
27
O A. Chemical energy to kinetic energy
O B. Kinetic energy to electrical energy
C. Thermal energy to kinetic energy
D. Light energy to electrical energy
Answer: B. Kinetic energy to electrical energy
Explanation:
The picture above depicts a hydro-electric power station where flowing water is used to generate electricity. It works by directing water to push against turbines which then turn and generate electricity through a generator connected to the turbines.
It is therefore converting the kinetic (motion) energy of the water to electrical energy that is generated by the generator.
Do the patterns of interactions between organisms, such as competition and predation, change when they occur in different ecosystems
Yes, there is change when they occur in different ecosystems because each ecosystem contains a different set of abiotic and biotic features that interact with each other.
What is competition?Competition is defined as the struggle for survival that exists between two similar organisms in an ecosystem where one who gains survives and the one that loses dies.
Predation is defined as the feeding interaction that exist between organisms whereby the one organism, the predator, kills and eats another organism, its prey.
The patterns of interaction between organisms such as competition and predation would change because each ecosystem contains a different set of abiotic and biotic features that interact with each other.

Researchers determine the population of phytoplankton in an area of the ocean is significantly decreased compared
to the previous year. What can they conclude from this observation? (1 point)
The plankton as a carbon sink will be less than expected, but the plankton as a carbon source will
be greater than expected.
The plankton as a carbon sink and as a carbon source in the area will be less than expected.
The plankton as a carbon sink will be greater than expected, but the plankton as a carbon source
will be less than expected.
O The plankton as a carbon sink and as a carbon source in the area will be greater than expected.
This information might be used to draw the conclusion that there will be fewer plankton in the region than is typical both as a carbon source and sink, hence B is the appropriate response to this question.
What is phytoplankton?The kind of organisms that live in watery habitats are known as phytoplankton.
These species are autotrophic in nature and are the producers of this ecosystem. These creatures share a characteristic with terrestrial plants in that they both contain chlorophyll.
Therefore, if the phytoplankton population falls in the coming year, it means that the region's carbon supply and sink will be less than anticipated.

which of the following structures in a plant cell is responsible for the production of food
Answer:
chloroplastExplanation:
Chloroplasts are specialized organelles found only in plants and some types of algae. These organelles carry out the process of photosynthesis, which turns water, carbon dioxide, and light energy into nutrients from which the plant can obtain energy. There can be over one hundred chloroplasts in certain plant cells.
Chloroplasts are disk-shaped organelles that are surrounded by a double membrane. The outer membrane forms the external surface of the chloroplast and is relatively permeable to small molecules, allowing substances entry into the organelle. The inner membrane lies just beneath the outer membrane and is less permeable to external substances.
Between the outer and inner membrane is a thin intermembrane space that is about 10-20 nanometers wide. The center of the chloroplast that is enclosed by the double membrane is a fluid matrix called the stroma (you can think of this like the cytoplasm of the chloroplast).
Within the stroma, there are many structures called thylakoids, which look like flattened disks. Thylakoids are stacked on top of one another in vascular plants in stacks called grand. Thylakoids have a high concentration of chlorophyll and carotenoids, which are pigments that capture light energy from the sun. The molecule chlorophyll is also what gives plants their green color.
The state of a medium helps determine the speed of sound passing through medium
True. The speed at which sound travels through a medium is determined by the properties of that medium.
What do you mean by sound?
Sound is a type of energy made by vibrations that travel through the air or another medium, like water. It is sensed by our ears and interpreted by our brains. Sound is made up of waves that have different frequencies, which determine the pitch and loudness of a sound.
Factors such as temperature, pressure, composition, and density can all affect the speed of sound in the medium. For example, sound travels faster through warmer air than through colder air, and faster through denser materials than through less dense materials.
Hence, the statement is True.
