Answer:
All animals are heterotrophic and have cells with no cell wall.
Explanation:
Since animals don't perform photosynthesis or any other process to make food, and don't contain a cell wall, that is what makes them different. Protist can be both autotrophic and heterotrophic and some can contain a cell wall, but most of them don't have cell walls.

When the Earth moves, the angle at which sunlight hits different places on Earth at the same time of day changes because the Earth is tilted.
What is Earth rotation?Earth's rotation or Earth's spin is defined as the rotation of the planet Earth around its axis as well as the change in the orientation of the axis of rotation in space. When viewed from Polaris, the north pole star, the Earth rotates in the east facing east, the Earth rotates counterclockwise.
When the heading of the particular place is towards the Sun, there is warm temperature which is called as the summer when the heading of the same place is away from the Sun, there is cold temperature which is called as the winter.
Thus, when the Earth moves, the angle at which sunlight hits different places on Earth at the same time of day changes because the Earth is tilted.

Answer:
chemical energy
Explanation:
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
How does the mutated protein differ from the original protein?
A mutant protein is the protein product encoded by a gene with mutation. Mutated protein can have single amino acid change (minor, but still in many cases significant change leading to disease) or wide-range amino acid changes by e.g. truncation of C-terminus after introducing premature stop codon.
What is protein? ... Most animal sources of protein, such as meat, poultry, fish, eggs, and dairy, deliver all the amino acids your body needs, while plant-based protein sources such as grains, beans, vegetables, and nuts often lack one or more of the essential amino acids.

The graphic shows a matching list: 'Roots' is matched with 'absorbs water and nutrients' and 'anchor the plant.' 'Stem' is matched with 'provide structural support and transport water and minerals.' 'Leaves' is matched with 'absorb sunlight.'
The completed plant tissues and the cells that initiate their growth
The differences between plant structures and the mechanism that produces them
The types of plant cells and their functions within the plant
The relationship between different structures in a plant and their functions
Answer:
The relationship between different structures in a plant and their functions
Explanation:
The roots, stem, and leaves are the different structures in a plant and they are matched to their functions (role/job). So the image represents how the different structures and functions correlate. Also, I took the test.

Parasitism
Predation
Answer:
mutualism
Explanation:
Commensalism is best represented by this graph.
What is an ecological relationship?It is the interaction and the result of it between two organisms. It can be either positive negative or neutral.
How many kinds of relationships can be there?It can be either mutualism, commensalism, amensalism, predation, parasitism, mutualism, symbiosis, etc.
What is commensalism?It is the type of interaction in which one species is unaffected while the other benefits from the relationship
How graph depicts commensalism?Since the population size of A is unaffected while the population size of B is increased (benefitted), we can say that it is commensalism

Photosynthesis is dependent on-
A :the nitrogen cycle
B: ammonia
C: the seasonal cycle
D: the carbon cycle
Answer:
The correct answer is - carbon cycle.
Explanation:
During the photosynthesis process, all plants consumed carbon dioxide from the atmosphere and sunlight to generate or produce glucose a biological fuel required for building structural components and produce energy. It forms the foundation of the carbon cycle.
Consumption of carbon dioxide is part of the carbon cycle. These biological fuels used in another process called cellular respiration that releases carbon dioxide into the atmosphere. Thus, the carbon cycle and photosynthesis both are interdependent.
Which of the following best supports the theory of continental drift?
A
South America and Africa have completely different rock layers.
B
A hurricane hits the Gulf of Mexico at the beginning of June.
C
Similar fossils are found on the coasts of South America and Africa.
D
North America and South America are connected by land.
Answer:
C
Similar fossils are found on the coasts of South America and Africa.
Continental drift is a hypothetical argument that affirms that the continents of the Earth shifted over the geological timeline. It says that the landmasses drifted over the oceans hence creating several continents and oceans.
The correct answer is:
Option C. Similar fossils are found on the coasts of South America and Africa.
The explanation for the correct answer is:
The continents either drifted away or clashed together to form present-day continents.Remains from similar species infer that South America and Africa used to be together.The theory of Pangaea states that all the continents were united once but due to a shift in tectonic plates the continents drifted apart.Therefore, alike fossils found in various continents supports the theory of continental drift.

Which of the following observations would provide the strongest evidence that two plants belong to different biological species?
A. There are variations in their RNA sequences.
B. The leaves and flowers show morphological differences.
C.They produce viable but sterile offspring.
D.They occupy unique habitats in an ecosystem. .
Answer:
the answer is C
Explanation:
Even if organisms of different species combine their DNA to make offspring, the offspring will be sterile, unable to pass on their genes. Because of this restricted gene flow, each species evolves as a group distinct from other species.
The observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).
The biological concept of species was developed by Ernst Mayr, who also develop the idea that species are metapopulation lineages.The biological concept of species states that mating between individuals of the same species produces viable offspring.The biological concept of species can be used to provide independent evidence for the presence of morphological and biological species.In conclusion, the observation of plants that produce viable but sterile offspring provides the strongest evidence that they belong to different biological species (Option C).

What is an organism that consumes a secondary consumer for energy?
Producer
Tertiary Consumer
Secondary Consumer

Primary Consumer
Secondary Consumer organism that consumes a primary consumer for energy.Tertiary Consumer organism that consumes a secondary consumer for energy. Therefore options "B" and "A" are correct.
What are primary and secondary producers?Primary producers are known as autotrophs. They generate energy from the sunlight. The process by which they produce energy is known as photosynthesis. Examples of organisms are algae, bacteria, higher plants, and some protists. These organisms also store this energy.
Secondary producers are the organisms and animals which feed on the primary producers. After consumption, they convert it into energy. The energy generated is known as ATP. The process by which the energy is generated is known as cellular respiration.
