Nebulae are Dust and gas where Stars can form, hence option A, B.

Although there are less than ten atoms per cubic meter in intergalactic space, it is not completely vacuum. Nature, after all, detests emptiness! When a few atoms are close enough to one another to clump together, a nebula starts to form. Naturally, the gravitational influence of atoms increases with the number of clumps they form. Eventually, a sizable gaseous cloud forms in space as a result of them being able to drag even more particles toward them.

A nebula is primarily a cloud of gas and dust in space; when there are several, they are collectively referred to as nebulae. Some of the most beautiful celestial phenomena are nebulae, and many of them have been given names that refer to things we are familiar with, like the land.

Therefore, option A, B are correct.

During G 1 phase and G 2 phase the cell grows and synthesizes proteins required during its division, while in the duplication S phase, the cell generates a duplicated genetic material in order to divide it. Finally, the M or mitotic phase is required to divide the cell.

The interphase and the mitotic phase of the cell cycle are two sequential processes where the cell grows and synthesize all required material in order to progress with the cell division life cycle.

The interphase of the cell cycle may be divided into different stages including G1, S duplication phase, and G2 phase.

Therefore, with this data, we can see that the interphase and the mitotic phase of the cell cycle are required to carry out the complete cell life cycle.

An autotroph is an organism that can produce its own food using light, water, carbon dioxide, or other chemicals. Because autotrophs produce their own food, they are sometimes called producers.Organisms are characterized into two broad categories based upon how they obtain their energy and nutrients: autotrophs and heterotrophs. Autotrophs are known as producers because they are able to make their own food from raw materials and energy. Examples include plants, algae, and some types of bacteria.

Number of albino cockroaches = 486 cockroaches

Explanation:

Assuming that the population is in Hardy-Weinberg equilibrium and that albinism is recessive, the Hardy-Weinberg equation is used to determine the frequencies ofnthe different alleles in the population

According to the Hardy-Weinberg equation : p² + 2pq + q² = 1

Also p + q = 1

Where p² is the frequency of cockroaches having similar alleles for the dominant trait;

2pq is the frequency of individuals with the heterozygous allele, while q² is the frequency of the individuals having similar allele the recessive trait, albinism.

q² = 24/666

q² = 0.036

Since, the frequency of albinism in the population 0.036, number of individuals with the recessive allele, that is albino cockroaches in the next generation is obtained by multiplying the frequency with the number of individuals in the next generation.

Number of albino cockroaches = 0.036 × 13485

Number of albino cockroaches = 486 cockroaches

Limiting factors affect a species' carrying capacity and are classified into density-dependent or density independent factors. A) Density-independent. B) Density-dependent. C) Density-dependent. D) Density-independent.

The carrying capacity might be affected by different factors, known as limiting factors, which might be a result of the population density or might be density-independent.

Scenario A:

A flood wipes out all the plant species that live on a riverbed.

The flood is a natural disaster, hence this is an example of density-independent factor.

Scenario B:

A pack of wolves migrates to a new valley and eats all the deer that inhabit that space.

This example makes reference to the interaction between wolves and deer, meaning this is a case of density-dependent factor.

Scenario C:

A large population of zebras is killed due to a contagious virus.

This is also a case of density-dependent factors, because the contagious virus spread is closely related to large and dense populations.

Scenario D:

A drought kills many of the deer that live in a valley.

This is an example of another natural disaster affecting deer population size, meaning we are talking about a density-independent factor.

Answer:

Through the process of natural selection, sea urchins have developed spines that serve as a defense mechanism against predators and a means of anchoring themselves in turbulent waters. This adaptation allows them to better survive in their environment, with individuals possessing longer or stronger spines being more likely to pass on their genes to the next generation. As a result, the population of sea urchins gradually becomes better adapted to their surroundings, demonstrating the power of natural selection in shaping the evolution of species.

Answer:

The carbon cycle is a fundamental process that encompasses the movement and transformation of carbon throughout the Earth's systems. It involves a series of interconnected steps through which carbon is exchanged between the atmosphere, oceans, land, and living organisms. At the heart of this cycle is photosynthesis, where plants absorb carbon dioxide from the air, converting it into organic matter and releasing oxygen. This process sustains life on Earth and acts as a crucial carbon sink. Once carbon is incorporated into plants, it can be transferred through various pathways. Some carbon is consumed by animals when they feed on plants, enabling it to become part of their bodies. Over time, organic matter can undergo decomposition, releasing carbon back into the atmosphere as carbon dioxide through the process of respiration or through the activity of decomposers. Additionally, carbon can be stored in long-term reservoirs such as fossil fuels or locked away in the oceans as dissolved carbon. Through geological processes, carbon can be released from these reservoirs, contributing to the carbon cycle once again.

Human activities have significantly impacted the carbon cycle, primarily through the burning of fossil fuels and deforestation. These activities release large amounts of carbon dioxide into the atmosphere, disrupting the natural balance of the cycle and contributing to climate change. The carbon cycle serves as a reminder of the intricate interconnections within our planet's systems and highlights the importance of understanding and managing carbon flows to maintain a stable and sustainable environment for future generations.

Answer:

During the process of photosynthesis, six molecules of carbon dioxide and six molecules of water react in the presence of sunlight to form one glucose molecule and six molecules of oxygen. The role of water is to release oxygen (O) from the water molecule into the atmosphere in the form of oxygen gas (O2).

Water is important for photosynthesis because it the source of hydrogen for the sugars created through photosynthesis
