Answer:
1. Nucleoid
2. Plasmid
Explanation:
Prokaryotes are groups of organisms characterized by the lack of a membrane-bound nucleus in their cell. Due to this, the genetic material (DNA) of prokaryotes are found naked i.e. not housed. The DNA of a prokaryote is arranged in a single coiled chromosome located in a region of the cell called NUCLEOID.
However, some prokaryotes e.g. bacteria carry genes on extrachromosomal pieces of circular DNA called PLASMID. Plasmids carry certain genes like antibiotic resistance genes.
Which of the following factors affecting population growth is density
independent?
A. Competition
B. Disease
C. Natural disaster
D. Predation
C. Natural disaster is a density-independent factor affecting population growth. Density-independent factors are those that affect the population irrespective of the population size or density.
How Natural disasters reduce population sizes?Natural disasters such as floods, hurricanes, earthquakes, and wildfires can reduce population sizes regardless of how many individuals were present in the population before the disaster occurred. The other factors listed - competition, disease, and predation - are all density-dependent factors, which means that they become more significant as the population size or density increases.
Competition is an example of a density-dependent factor, as it increases as the population size increases. As more individuals compete for limited resources such as food, water, and shelter, the rate of population growth slows down.
Disease is another density-dependent factor, as it spreads more easily in crowded populations where individuals are in close contact with one another.
On the other hand, natural disasters such as floods, hurricanes, and wildfires are examples of density-independent factors. These events can affect a population regardless of its size, and they can cause significant decreases in population size.
Predation can be both a density-dependent and density-independent factor. In some cases, predation can increase as the population size increases, making it a density-dependent factor. However, predators can also reduce the population size through random hunting or selective hunting of weaker individuals, making it a density-independent factor.
Understanding the factors that affect population growth is important for predicting and managing population sizes in both natural and human-made ecosystems.

Why dont plant cells have microvilli?
Answer: They don’t have microvili because they don’t need it.
Explanation:
Animal cells have this because it increase surface area and helps absorb food and water molecules.
Plant cells do not have microvilli because they do not require the same type of surface area enlargement as animal cells.
Microvilli are small, finger-like projections that extend from the surface of animal cells. They help to increase the surface area of the cell, which is important for functions such as absorption and secretion.
Whereas plant cells have a rigid cell wall that provides structural support and protection. They have evolved unique structures to meet their specific needs, such as chloroplasts for photosynthesis and a cell wall for support and protection.
So, the absence of microvilli in plant cells is not a disadvantage since they do not require the same surface area enlargement as animal cells.
Therefore, the absence of microvilli in plant cells is due to their unique structural and functional needs.

Natural selection is a mechanism of evolution. Organisms that are more adapted to their environment are more likely to survive and pass on the genes that aided their success. This process causes species to change and diverge over time.

Wheathering is the process of breaking of the rocks or soil. It can be of different types on the factors such as chemical wheathering, physical wheathering and biological wheathering.
When a seed fall on to on a rock surface its sprouts, push roots into cracks in the rock or concrete. As the roots of plants develop, they secrete weak acids that slowly dissolve rock around the roots.
It is a type of biological wheathering.

The image shows a rain forest ecosystem. The energy from plants, or producers, acts as the starting point of energy in the ecosystem. This energy is transferred to other organisms in the food web. In which two ways is the total amount of energy conserved in the ecosystem?
Some energy is transferred to the organisms, and the remaining energy is released into the ecosystem as thermal energy.
Bacteria eat the dead bodies of organisms to release the organisms’ stored energy into the atmosphere.
Some energy is transferred to the smaller organisms, and the rest is stored in the bodies of larger animals.
Some energy is transferred to the organisms, and the rest is released by plants in the form of carbon dioxide.
Bacteria eat the dead bodies of organisms, obtain all the energy, and store it in their bodies.

Explain how fluctuations in abiotic cycles can influence populations.
Answer:
Populations are influenced by fluctuations in any of the abiotic cycles. The fluctuation of seasonal cycles can cause populations to hibernate, migrate, or breed. Organisms hibernate as a result of seasonal fluctuations that cause them to have a limited resource supply.

Why do you think it is functionally important that the bones of the os coxae fuse together rather than remain independent bones
Answer:
Provides more strength.
Explanation:
It is functionally important that the bones of the os coxae fuse together rather than remain independent bones because the fusion of bones of the os coxae increases their strength and they can perform their function very well. If the fusion of bones of the os coxae did not occur and they remain independently so they can't bear the load of the body and so the function is also adversely affected.
Which type of selection is also known as diversifying selection because it tends to favor the survival of two or more different phenotypes in a heterogeneous environment
Answer:
Disruptive selection.
Explanation:
Disruptive selection is also called diversifying selection because it favor the survival of two or more different types of phenotypes in a particular environment. Disruptive selection describes changes in population in which extreme values for a trait are favored whereas the intermediate values are less favored. Due to the increase the variance of the trait which leads to the division of population into two distinct groups.

How is The processes of photosynthesis and respiration are interrelated
[tex]\color{Black}\huge{Answer} [/tex]
Photosynthesis converts carbon dioxide and water into oxygen and glucose. Cellular respiration converts oxygen and glucose into water and carbon dioxide. Water and carbon dioxide are by- products and ATP is energy that is transformed from the process.Answer:
Carbon dioxide and water are converted to oxygen and glucose through photosynthesis.
Oxygen and glucose are converted into water and carbon dioxide through cellular respiration.
By-products include water and carbon dioxide, while ATP is the energy generated by the process.
Explanation:
Plants use light water and carbon dioxide to make energy (glucose) and oxygen through photosynthesis. The oxygen is released into the atmosphere while the glucose powers the plant's operations. The process through which animals mix glucose and oxygen to make carbon dioxide and water is known as cellular respiration.
Photosynthesis end product is glucose utilised for the production of ATP in the cellular breathing. Glucose is then returned to carbon dioxide, needed for photosynthesis. During photosynthesis, the water is broken down into oxygen, but oxygen is mixed with hydrogen into water in cell respiration.
