1. (b) Where does the light independent phase of photosynthesis occur?
Explanation:
The light-independent reactions of photosynthesis take place within the stroma. It contains enzymes that work with ATP and NADPH to “fix” carbon from carbon dioxide into molecules that can be used to build glucose. The chloroplast's own genetic material (separate from that of the cell) is also stored in the stroma.
Which statement could be supported by the graph?
Time versus Population Density Graph
a. The number of frogs will decrease in response to an increase in the fly population.
b. The number of grasshoppers will increase in response to an increase in the bird population.
c. The number of coyotes will decrease in response to an increase in the rabbit population.
d. The number of hawks will decrease in response to a decrease in the mice population.
Answer:
d
Explanation:
As the number of prey decrease, the number of predators will naturally decrease. Therefore, in option D, where hawks are the predators and mice are the prey, makes the most sensible answer.
Statement :
The number of hawks will decrease in response to a decrease in the mice population.
As per the graph, the correct answer here is that the number of hawks will decrease in response to a decrease in the mouse population, which is option D, as the rise of the predator would lead to the fall of the prey number in the ecosystem.
What is the prey-predator graph?A prey-predator graph is a graphical representation of the relationship between a population of prey and their predators, and the graph shows how the population sizes of prey and predators change over time and how they affect each other. Prey and predator populations are closely linked. When there are more prey, there is more food available for predators, so predator populations tend to increase. However, as predator populations increase, they begin to consume more prey, which causes the prey population to decrease. As the prey population decreases, the predator population may also decrease due to a lack of food. This creates a cycle of predator-prey population fluctuations that can be observed on a prey-predator graph.
Hence, As per the graph, the correct answer here is that the number of hawks will decrease in response to a decrease in the mouse population, which is option D.

Which phrase should be written in the column titled "always"? have a backbone are warm-blooded are multicellular eat plants
The correct phrase would be that warm-blooded animals always have a backbone.
What warm-blooded animals?They are animals whose body temperature does not fluctuate with the temperature of the environment.
Warm-blooded animals have a system in place that ensures that the temperature of their body does not fluctuate significantly. The process by which this is achieved is called homeostasis.
Warm-blooded animals are advanced animals in the chordate group. Chordates have notochords that develop into the brain and the spinal cord in several animals.

External appendages that stick to other cells and surfaces, which may give rise to aggregates known as biofilms and colonization of microbes on inanimate objects, are known as fimbriae.
What are biofilms?Bacterial biofilm is a major cause of medical device contamination and the spread of infectious and chronic diseases throughout the body. Biofilms, in generally, are the genesis of a variety of human diseases, as they can lead to significant infections and are resistant to antimicrobial drugs.
Fimbriae are long filamentous polymeric protein structures present on bacterial cell surfaces. They allow bacteria to fuse to specific receptor structures and colonize specific surfaces as a result.

Which is a negative effect of deforestation on the environment?
habitat restoration
desertification
soil production
urbanization
The negative effect of Deforestation on the environment includes biodiversity loss, soil erosion, water pollution, and desertification. So option B is correct.
What is meant by deforestation?Deforestation is the process of removing trees from a forest to facilitate human activities. Deforestation is a major environmental issue as it can lead to biodiversity loss, habitat destruction, water pollution, and soil erosion.
The most common definition of deforestation is the felling of trees by humans. However, deforestation can also be caused by natural events such as floods or fires. Deforestation is most commonly used to clear land for agricultural purposes or to harvest timber from fallen trees.
The rapid decimation of forests is causing a biodiversity crisis unprecedented in history. The primary impact of deforestation on wildlife is habitat destruction. Many factors associated with the destruction of trees contribute to the extinction of species. Land erosion removes nutrients from the soil, which is a major source of food for animals and plants.

Is quartzite a mineral, a rock, or neither?
there are 3 ways that thermal energy can be transferred below write a paragraph describing each one with an example
Answer:
Thermal energy can be transferred by conduction, convection or radiation
Explanation:
Thermal energy is the energy that flows from one point to another due to temperature differences between the points. There are three ways by which thermal energy is transferred which are conduction, convection and radiation.
In conduction, thermal energy is transferred in solids usually metals due to their good heat conductivity. An example is seen in the use of metals for preparing meals. Heat (or thermal energy) is transferred from the fire to the metal to the food.
Convection occurs in fluids (liquids and gases). It usually occurs in a cyclic manner. For example in heating water, thermal energy is gained by water molecules closest to the heat source (at the base of the container) and become lighter causing them to rise to the top. The molecules at the top become denser and sink to the bottom whereby they gain energy and rise in a similar manner. This repeated phenomenon occurs in a cyclic form whereby there's displacement of colder and denser molecules by warmer and lighter molecules. Another example is the occurrence of sea and land breezes.
Radiation occurs without the need of any material medium unlike conduction and convection. In radiation, heat is directly transferred from one point to the other without being transferred by molecules. This is seen in how thermal energy from the sun reaches the earth. In other words, heat is transferred in a vacuum

Which of these organisms
has cells that lack a cell
wall?
A. trees
B. fungi
C. plants
D. animals
Animal cells do not have cell walls because they do not need them. Cell walls, which are found in plant cells, maintain cell shape, almost as if each cell has its own exoskeleton. Animals do have a cell membrane though.
What are cell walls?A rigid layer of nonliving material that surrounds the cells of plants and some other organisms. A cell wall is made up of cellulose, pectin, glycoproteins, hemicellulose and lignin. It is the outer boundary of the cell, it encloses the cytoplasm and the organelles of the cells. In plants cells it is inside the cell wall.
Let's take a look at the options:The first one is a tree. A tree is a type of plant and all plants have cell walls and it provides turbidity and durability for the plant. Therefore, a tree has a cell wall eliminating it as a option.The second one is fungi. Fungi are a eukaryotic organism that is usually filamentous (forming a mycelium) and heterotrophic. Fungi have a cell wall made of chitin, a nitrogen containing polysaccharide (NO amino acids) called hyphae. Therefore, fungi have a cell wall eliminating it as a option.The third one is plants. As mentioned before, all plants have cell walls. But to explain more, plant cells are surrounded by a strong cell wall that can change as they grow. It is made of a mixture of polysaccharides cross-linked together, which can give properties like flexibility, strength, turgor and waterproofing. Therefore, plants have a cell wall eliminating it as a option.The last one is animals. Animal cells have a cell membrane instead of rigid walls like plant cells do and that is mainly so they can move. Rigid cell walls don’t move - plants don’t move very much and what movement they do have is very slow and gradual. Animals move constantly - skin has to stretch, muscles must contract and extend. So the cells have to allow for that, and the flexible cell membrane is how they do it. Therefore, the answer is option D.To learn more about cell functions, check out these links:
