Answer:

represents the flow of water through its concentration gradient, through a semi-permeable membrane.

Explanation:

This means that water flows from where it is in a higher concentration to a place where it is in a lower concentration to try to equalize the concentrations of both solutions.

Osmosis is an example of diffusion when molecules tend to be evenly distributed in space.

Explanation:

Nucleus part main job is to direct a plant cell's activities by sending instructions to different parts of the cell.

Plant cells are eukaryotic cells with a genuine nucleus and particular organelles to carry out particular tasks. Plant cells do, however, include several organelles that are unique from those seen in other eukaryotic cells.

Roots, stems, leaves, flowers, and reproductive structures are only a few of the major classes of cells and tissues that are formed when plant cells differentiate from undifferentiated meristematic cells, which are similar to the stem cells of animals.

Answer:

The correct answer is - The decomposers decompose dead algae and plants which take up most of the oxygen.

Explanation:

Eutrophication is taken place when there is a high amount of nutrients, minerals are present in a waterbody which allow algae to grow rapidly and cause depletion of oxygen due to the decomposition of dead organisms. There are the following stages in the eutrophication process:

-  rapid growth of Algae and other plants

- due to algal bloom, the sunlight is blocked, and plants and organism start dying.

- The decomposers take up most of the oxygen by decomposition

- The animals start dying without oxygen

Answer:

Explanation:

In geology, petrifaction or petrification is the original material and the filling of the original pore spaces with minerals. Petrified wood typifies this process, but all organisms, from bacteria to vertebrates, can become petrified. Petrification (petros means stone) occurs when the organic matter is completely replaced by minerals and the fossil is turned to stone. This generally occurs by filling the pores of the tissue, and inter and intra cellular spaces with minerals, then dissolving the organic matter and replacing it with minerals. Researchers at UCLA and the University of Wisconsin–Madison have confirmed that microscopic fossils discovered in a nearly 3.5 billion-year-old piece of rock in Western Australia are the oldest fossils ever found and indeed the earliest direct evidence of life on Earth.

Explanation:

The inheritance of flower color in the plant species follows the simple dominance/recessive inheritance of Mendel. The red flower trait did not show up at all at F1 only for it to show up at F2. It simply means that the red flower trait is recessive while the violet flower color is dominant.

Assuming that the allele for violet flower color is designated as R while that of red flower color is designated as r.  The genotype of the violet flower would be true-breeding, RR, while that of red flower color would also be true-breeding rr:

                RR    x    rr

 F1         Rr    Rr    Rr    Rr  

phenotype ratio = all violet flower color

                 Rr    x    Rr

F2          RR    Rr    Rr    rr

phenotype ratio = 3/4 violet flower color and 1/4 red flower color

97 red flower offspring out of 400 is approximately 1/4.

Hence, the inheritance of flower color in the plant obeys a simple dominant/recessive Mendelian law with the violet color trait dominant over the red color trait.

Explanation:

We know relatively little about deep sea ecosystems, making it harder to assess the impact of mining.

Deep sea mining has never been tried successfully, so we don't know exactly how it can be done so it is difficult to know the impact of deep sea mining.

The process of extracting and often excavating mineral deposits from the deep seafloor is known as deep-sea mining.

The deep bottom spans around two-thirds of the total seafloor and is found at ocean depths greater than 200 meters.

Deep-sea mining has been shown to affect marine biodiversity and ecosystems, but we still lack the knowledge and resources to safeguard them.

There are considerable gaps in our understanding of the deep sea's biodiversity and ecosystems since it is still understudied and poorly understood.

This makes assessing the possible effects of deep-sea mining and putting in place necessary safeguards to protect the marine ecosystem and the three billion people whose livelihoods rely on marine and coastal biodiversity challenging.

Hence , the correct option is A.

Answer:

False

Explanation:

A limiting factor is the environmental factor that is of predominant importance in restricting the size of a population.

A limiting factor is an environmental factor that increases the growth of population-This statement is false.

In biology, the term restricting component is characterized as a natural element or variable that has the ability to limit the development, overflow, or appropriation of a populace in an environment. These elements are available in restricted supply. Subsequently, creatures will generally vie for their restricted accessibility in the environment.

Thus, Limiting factor does not increase the growth of the population.

Answer: 2. Population bottleneck

Explanation:

A Population bottleneck is a term used to refer to an event that causes the population of a species to reduce in very large numbers. Such an event can be environmental disasters like famine, the overhunting of a species or the destruction of its habitat.

In the case of the Cha-tham Island Robin, the bottleneck event must have been the introduction of cats and rats which then went on to hunt the birds to near extinction.
