Answer:
The cellulose cell wall in plants
Explanation:
All eukaryotic cells, both plant and animals cells have a cell membrane which is an outer covering of the contents of the cell. Also plants and animals cells have many structures and cell organelles in common such as the mitochondria, the endoplasmic reticulum, ribosomes, golgi bodies, etc. However, plant cells have a more rigid structure than animals cells because of the presence of an extra structure known as the cell wall, covering their cell membranes.
The cell wall is a rigid layer that is found outside the cell membrane and surrounds the cell, providing structural support and protection. The cell wall is composed mainly of cellulose, but contains proteins as well as other polysaccharides too.
Another structure present in plants that serves to maintain the rigidity of the plant cell is the large central vacuole. The main role of the vacuole is to maintain turgor pressure by pushing the plasma membrane against the cell wall due to the pressure of fluids contained within it.

Developing 150 breeds of dogs from ancestral wolves is not an example of natural selection.
The process through which populations of living things adapt and change is known as natural selection. A population's members are naturally varied, which means that they are all distinctive in some ways. This variety indicates that some people have characteristics that are more environment-appropriate than others. People that possess advantageous qualities, or adapted traits, are more likely to live and procreate. The adaptable qualities are subsequently passed on to the next generation by these people. These beneficial characteristics spread across the population over time. Favorable features are passed down across generations as a result of natural selection. Natural selection may result in speciation, the process by which one species gives rise to another that is utterly separate.
Hence, survival of the fittest species take among population.

How is the earthworm’s reaction to light an adaption for living in the soil?
Answer:
Adaptation feature
Explanation:
Light-sensitive cells are scattered in their outer skin, mainly at the ends of their bodies. They allow earthworms to detect light and changes in light intensity. Earthworms don't use a nose, mouth or lungs to breathe like we do. In other words, earthworms don't have eyes like we do. Instead, they can sense light through their skin. These natural light sensors let the earthworms know when they are getting too close to a bright light, such as the sun. Earthworms try to stay out of sunlight because the heat from the sun dries out their skin.

Explanation:
Pls help I don’t understand
Genetic code is the term used to describe the instructions sent by a gene to a cell on how to produce a certain protein.
Thus, Adenine (A), cytosine (C), guanine (G), and thymine (T) are the four nucleotide bases of DNA that are used in different ways by each gene's code to create three-letter "codons" that describe which amino acid is required at each location within a protein.
The history of the genetic code relates the hopes and dangers of biology and genetics throughout the 19th, 20th, and 21st centuries.
For instance, Oswald Avery put an end to more than 80 years of fruitful conjecture in 1944 when he demonstrated that the genetic code—that is, DNA—was in fact the carrier of hereditary information.
The genetic code is a set of instructions that enable live cells to produce proteins using genetic information contained in DNA or RNA sequences of nucleotide triplets, or codons.
Thus, Genetic code is the term used to describe the instructions sent by a gene to a cell on how to produce a certain protein.

The population of the town after 10 years. will be 2150. The correct option is B.
What is population?All the members of the same group or species that reside in a given area and are able to reproduce among themselves are referred to as a population in biology.
A group of creatures of a single species that can breed together and coexist in the same habitat are referred to as a "population."
Quantity rises over time through a process called exponential growth. When a quantity's instantaneous rate of change with regard to time is proportionate to the quantity itself, it happens.
Exponential growth can be written as:
\(f(x)=a(1+r)^x\)
Here,
a = 1600
r = 3% = 0.03
x = 10 years
So,
\(f(x)=1600(1+0.03)^1^0\)

Bacteria break down (or decompose) dead organisms, animal waste, and plant litter to obtain nutrients. But microbes don't just eat nature's waste, they recycle it. The process of decomposition releases chemicals (such as carbon, nitrogen, and phosphorus) that can be used to build new plants and animals.

How does adenosine triphosphate (ATP) become adenosine diphosphate (ADP)?
ATP stores energy as a phosphate bond is formed.
ATP releases energy as a phosphate bond is formed.
ATP releases energy as a phosphate bond is broken.
ATP stores energy as a phosphate bond is broken.
The correct answer is ATP releases energy as a phosphate bond is broken.
ATP (adenosine triphosphate) is converted into ADP (adenosine diphosphate) when a phosphate group is removed from ATP, resulting in the release of energy. This process is known as hydrolysis, where water molecules are used to break the bond between the terminal phosphate group and the rest of the molecule.
During cellular metabolism, ATP serves as the primary energy currency of the cell. When energy is required for various cellular processes, the phosphate bond in ATP is broken by an enzyme called ATPase. This enzymatic hydrolysis reaction cleaves off one of the phosphate groups, resulting in the formation of ADP and an inorganic phosphate molecule (Pi). The released phosphate group is then available to be used in other cellular reactions.
The conversion of ATP to ADP is an essential part of energy metabolism in cells. The energy released during this process is utilized to drive various cellular activities, such as muscle contraction, active transport of molecules across cell membranes, and synthesis of macromolecules. Once ATP is converted to ADP, it can be further hydrolyzed to AMP (adenosine monophosphate) if more energy is needed. Ultimately, the energy stored in ATP is released when the phosphate bond is broken, allowing cells to perform their vital functions.

-open,sunlit(photic) surface away from shore -main photosynthetic zone,food and oxygen support most lake life -lots of phytoplankton and zooplankton
The open and sunlit (photic) surface away from the shore is known as the main photosynthetic zone in a lake.
This area is crucial as it provides food and oxygen to support most of the lake's life. It is abundant in phytoplankton and zooplankton, which form the base of the food chain and support various species of fish and other aquatic animals. The photic zone receives ample sunlight, making it ideal for photosynthesis to occur, providing energy and oxygen to sustain the diverse ecosystem within a lake.
This zone also acts as a habitat for many aquatic plants, algae and microorganisms. These organisms provide food for herbivores, such as zooplankton and small fish, which in turn become prey for larger fish and other predatory species. The photic zone is a vital component of a lake's ecosystem, as it is where the primary productivity takes place and supports the entire food chain. The health of this zone is important as any changes or disruptions can impact the entire lake ecosystem, making it essential to monitor and maintain the balance of this zone.
