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.

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.

B. Analogous structure

Explanation:

The wings of a bat and a butterfly perform similar function. They are believe to have evolved differently from different ancestors, however, they perform the same function.

Such structures are referred to as Analogous structures.

Analogous structure like the wing of butterfly and bat appear similar and perform similar function. They have evolved separately to become adapted to perform similar function.

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.

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.

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.

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.

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.

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.

Fats are hydrophobic and serve as large energy stores in the body of animals.

The enzymes involved in fat digestion are known as lipases.

During fat digestion, They are first emulisified by bile before action by lipases.

Cream contains fats and are first emulsified before action by lipases.

The relative abundance of species in a community is known as species evenness. Therefore, option C is correct.

Species evenness refers to the measure of the relative abundance of different species within a community or ecosystem. It describes the balance of the distribution of individuals among the different species present in a particular area.

For example, a community with high species evenness would have similar numbers of individuals in each species, while a community with low species evenness would have a few dominant species with many individuals and many less abundant species with fewer individuals.

Species evenness is often used in conjunction with species richness, which refers to the total number of different species present in a community, to provide a more complete picture of the biodiversity of an area. Thus, option C is correct.

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.

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.

Explanation:

The immune response contributes to homeostasis by helping to fight off infection and heal after infection or trauma. During an infection, molecules called pyrogens are released, which alert the brain to increase the temperature of the body, causing a fever

The homeostatic response when the human body is fighting an infection is negative feedback, increasing body temperature; that is the third option, as increasing body temperature helps to inhibit the growth and replication of pathogens and also enhances the immune response.

When the body is fighting an infection, it triggers a complex set of responses to try to restore homeostasis and overcome the infection. One of these responses is the activation of the immune system, which produces various cells and molecules to fight off the invading pathogens.

One of the most important homeostatic responses during an infection is the increase in body temperature, which is known as fever. The body's thermostat, which is located in the hypothalamus of the brain, is set to a normal temperature of around 37°C (98 °F). However, during an infection, the body may raise its temperature to 38°C (100.4°F) or higher.

Hence, the homeostatic response when the human body is fighting an infection is negative feedback, increasing body temperature; that is the third option.

Answer:

Explanation:

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.
