what is autotroph class 7
answer in 5 sentences
pls I need answer ASAP
Whoever answers will be marked brainliest
In biology, autotrophs are organisms that can produce their own food using inorganic substances, such as sunlight and carbon dioxide.
How do we explain?Autotrophs are also known as primary producers because they form the base of the food chain by converting energy from the environment into organic compounds.
The topic of autotrophs is typically covered in the study of plant biology in the context of a class 7 curriculum.
The most prevalent kind of autotrophs are plants. They do this through a process known as photosynthesis, which turns carbon dioxide, water, and sunlight into glucose (a sugar) and oxygen.
Chloroplasts, specialized organelles found in plant cells, are where this process occurs.

a. the cell rests before it moves to a level of high activity
b. the cell creates copies of its DNA or genetic material
c. the cell divides into two new cells
d. the nucleus divides in half
b. the cell creates copies of its DNA or genetic material
During the S (synthesis) phase of interphase, the cell undergoes DNA replication. This means that the cell creates copies of its DNA or genetic material. The DNA in the cell is duplicated to ensure that each daughter cell produced during cell division will receive a complete set of genetic information. This phase is critical for cell division and the transmission of genetic material to offspring cells.

Provide an example of at least one interaction for each pair of spheres. 1. lithosphere and atmosphere: 2. lithosphere and hydrosphere: 3. lithosphere and biosphere: 4. hydrosphere and atmosphere: 5. hydrosphere and biosphere: 6. atmosphere and biosphere:
1. Lithosphere and Atmosphere: Weathering - rocks break down due to exposure to wind, water, and temperature changes. 2. Lithosphere and Hydrosphere: River formation - water erodes and shapes the land, creating river systems. 3. Lithosphere and Biosphere: Plant growth - roots extract nutrients from the lithosphere, stabilizing soil and contributing to ecological balance. 4. Hydrosphere and Atmosphere: Evaporation - water from oceans, lakes, and rivers changes to vapor and enters the atmosphere. 5. Hydrosphere and Biosphere: Aquatic ecosystems - water supports diverse life forms, providing habitats for aquatic organisms. 6. Atmosphere and Biosphere: Photosynthesis - plants use carbon dioxide from the atmosphere to produce oxygen and organic compounds.
1. Lithosphere and Atmosphere: An example of interaction between the lithosphere and atmosphere is the process of weathering. Weathering involves the breakdown and alteration of rocks and minerals on the Earth's surface due to exposure to atmospheric conditions.
The lithosphere, which consists of the Earth's solid outer layer, is constantly subjected to various weathering agents present in the atmosphere such as wind, water, and temperature changes. Over time, these agents can cause physical and chemical changes to the rocks, leading to their erosion and transportation.
2. Lithosphere and Hydrosphere: An example of interaction between the lithosphere and hydrosphere is the formation of rivers. Rivers are created when water flows over the Earth's surface, carving channels into the lithosphere.
As water from precipitation or melting ice moves across the land, it erodes and transports sediment, shaping the landscape and forming river systems.
The lithosphere provides the landmass and geological features through which the rivers flow, while the hydrosphere supplies the water necessary for their formation and sustenance.
3. Lithosphere and Biosphere: An example of interaction between the lithosphere and biosphere is the growth of plants. Plants depend on the lithosphere for anchorage and access to nutrients.
The roots of plants penetrate the lithosphere, extracting essential minerals and water necessary for their growth and survival. In return, plants play a vital role in the lithosphere by stabilizing the soil with their root systems, preventing erosion, and contributing to the overall ecological balance of the biosphere.
4. Hydrosphere and Atmosphere: An example of interaction between the hydrosphere and atmosphere is the process of evaporation. Evaporation occurs when water from oceans, lakes, and rivers is heated by the Sun, causing it to change from a liquid state to water vapor and enter the atmosphere.
This water vapor then contributes to the formation of clouds and plays a crucial role in the Earth's water cycle, eventually leading to precipitation and the replenishment of the hydrosphere.
5. Hydrosphere and Biosphere: An example of interaction between the hydrosphere and biosphere is the existence of aquatic ecosystems. These ecosystems, such as oceans, lakes, and rivers, support a wide range of life forms.
They provide habitats for various organisms, including fish, marine mammals, and aquatic plants. The hydrosphere provides the necessary water and nutrients for these organisms to thrive, while the biosphere, in turn, influences the hydrosphere through biological processes like nutrient cycling and oxygen production.
6. Atmosphere and Biosphere: An example of interaction between the atmosphere and biosphere is the process of photosynthesis. Plants and some microorganisms in the biosphere use carbon dioxide from the atmosphere, along with sunlight and water, to undergo photosynthesis.
Through this process, they convert carbon dioxide into oxygen and produce organic compounds that serve as a source of energy for themselves and other organisms. The atmosphere provides the necessary carbon dioxide and oxygen for photosynthesis to occur, while the biosphere plays a critical role in maintaining the balance of atmospheric gases and sustaining life on Earth.

Explain the following statement using evidence from the DNA sequences:
Mutations in the DNA change how proteins are made which leads to new and different forms of phenotypes.
A missense mutation is a Genetic alteration that causes the protein produced to encode a different amino acid at a specific location. Certain missense mutations change how the resulting protein functions.
Why do some changes in an organism's DNA sequence cause change, while others do not?While mutations always result in a change in the DNA sequence, they do not necessarily have a noticeable impact on the organism or alter the resulting protein. Since most amino acids can be encoded by two or more distinct codons, this is possible.
Can mutations be found using DNA sequencing?The ability to properly identify and characterise the majority of sequence changes makes direct DNA sequencing, in theory, the method for mutation identification with the highest degree of accuracy.

4. In the winter a of people put a waxy layer of chapstick on their lips, ? Explain your answer by discussing the structure of the skin differs between our lips and the rest of the face .
The skin on our lips differs from the skin on the rest of our faces in a few ways. First, the lips have no oil glands, which means they don't produce natural oils to keep them hydrated.
Second, the lips are very thin, which makes them more susceptible to drying out. Third, the lips are constantly exposed to the elements, such as cold air, wind, and sun exposure.
These factors can contribute to chapped lips, especially in the winter. When the weather is cold, the air is drier, which can further dehydrate the lips. Additionally, the cold air can irritate the lips, making them more likely to crack and peel.
Chapstick helps to protect the lips from the elements and keep them hydrated. The waxy layer of chapstick creates a barrier between the lips and the air, which helps to prevent moisture from evaporating. Some chapsticks contain ingredients that help soothe and heal chapped lips.

The phylogenetic tree shows evolutionary relationships between taxonomig groups. 1) b. False. 2) c. Outroup. 3) b. At the end of a branch. 4) b. At a mark crossing the branch for the species that exhits the new state
The phylogenetic tree is composed of,
Lineages → The taxonomic groups of interest. These are placed in the extremes of the branches. Nodes → These are the ramification points, which are also known as divergence points. They represent the location of the most recent common ancestor. Root → This is the older common ancestor that all lineages share. The first one in the tree.⇒ Highly related groups that share a recent common ancestor. This means that they all diverge from the same node.
⇒ Lineages less related to each other are those whose common ancestor is far away in history.
⇒ The most distant group receives the name of the outgroup.
The outgroup shares no traits or derived characters with the lineages of interest that compose the ingroup. The outgroup can be compared with the ingroup to determine the evolutive relationship and which characters are primitive or derived.Even though the outgroup shares a common ancestor with the ingroup, this is placed far away in evolution, making the outgroup to be the taxonomic group less related to the other lineages. The lineages in the ingroup share another common ancestor that is more recent in history.
1) b. False
The discovery of new species can lead to a change in the original structure of the phylogenetic tree. It can also lead to the addition of new branches.
2) C. Outgroup
The outgroup is the ancestral lineage in the phylogenetic tree that expresses the ancestral state of every character. It is to compared to the ingroups to determine evolutive relationships.
