Plants are eukaryotic, multicellular, have cellulose walls and prepare their own food.

They are eukaryotic, multicellular, have cellulose walls and autotrophic are the characteristics that all species belonging to the plant kingdom have in common.

The numbers of stomata differs in tropical plants and desert plant because tropical plants have plenty of water in their environment while on the other hand, desert plants have lower number of stomata in order to conserve more water and increase its survival.

If a plant's xylem and phloem become damaged, the plant can't transport water and food to its other parts. The role of xylem is to transport water from roots to upper region while on the other hand, the phloem serves the transportation of food from leaves to other parts of the plant.

Flowering plants reproduce through a process called pollination in which pollens fuse with the female cells called ovules. The dermal tissue of plants is similar to human skin because both layers protects the inner parts.

The major cells of the ground tissue are parenchyma cells which perform the function of photosynthesis and nutrient storage so if this ground tissue is damaged then the plant can't survive.

Explanation:  flowers can help other organisms in the environment by giving them nectar in exchange for pollination as a mutual relationship.

Depending on the male or female side there are multiple parts but the Stamen is one of them which contains the anther and filament to help reproduction. The anther which produces the male sex cells, the pistil which Is female and holds the female gametophytes, the ovary which produces female sex cells, and the stigma which collects the pollen grain.

During seed development the ovary surrounding it gets larger and becomes a fruit and the seeds of the fruit disperse in many ways but that’s unrelated to it developing.



A flower might be bright in color to attract pollinators to help the flower reproduce.

Answer:

Nucleic Acid

Explanation:

The monomer of nucleic acids is an nucleotide. When several nucleotide is joined together they form DNA or RNA, which store the genetic material of an organism.  

In bacteria, translation of the mRNA begins near the 5' end of the mRNA molecule, when an mRNA binds to the small ribosomal subunit. In these organisms, transcription and translation occur simultaneously.

In bacteria, mRNA translation initiation starts immediately after the 5' end of the messenger RNA (mRNA) molecule is synthesized.

In these prokaryotic organisms, transcription and translation are processes that occur in a coupled manner.

During translation initiation, bacterial mRNA binds with the small ribosomal subunit, which is facilitated by a short ribosomal-binding site localized close to the 5′ end of the mRNA.

The number of plants with white flowers that you would expect to find would be the same number of plants with white flowers as there were the previous year.

The Hardy-Weinberg (PHW) is a scientific principle published in 1908 in which it is stated that the genetic composition of a population remains in equilibrium as long as natural selection or any other factor does not act and no mutation occurs.

According to the above, if a population of 50 plants of which 25 have white flowers, it could be inferred that the next year this population would have the same amount of population with white flowers thanks to the Hardy-Weinberg principle.

dinosaurs and birds

The two organisms that are most closely related are dinosaurs and birds.

Organisms are related because they share a common ancestry, meaning they have evolved from a common ancestor through genetic and evolutionary changes over time.

Based on the tree above, the two organisms that are most closely related are dinosaurs and birds. This is because birds are descended from a group of small, feathered dinosaurs that lived during the late Jurassic period, and are therefore considered to be a type of dinosaur.

The branch point where birds diverge from other dinosaurs is relatively recent on the tree, indicating that they share a more recent common ancestor than other organisms on the tree. In contrast, ray-finned fishes and sharks, rodents and primates, and dinosaurs and crocodiles diverged from each other at earlier points in evolutionary history, indicating that they are less closely related to each other than dinosaurs and birds.

Explanation:

If you start with 60 and end with 60, then no change has occurred. Mitosis is part of cell replication, so if we end with the same number as we started with, then no form of mitosis has occurred.

I hope this helps! :)

If we begin with 60 chromosomes and end with 60 chromsomes, then there has been no change. As mitosis is a component of cell replication, no mitosis has taken place if we reach the same number of cells as when we began.

Chromosomes that have been duplicated are splitting into two new nuclei during the cell cycle phase known as mitosis. Mitosis, the process of cell division, creates genetically identical cells with a constant number of chromosomes. Hence, equational division is another name for mitosis.

Mitosis is a process used to create more cells that share the same genetic makeup as the parent cell. It is essential to the expansion and development of human bodies as well as for the embryonic development of living things. Mitosis generates new cells and replaces injured, destroyed, or ageing ones.

Thus, if we begin with 60 chromosomes and end with 60 chromsomes, then there has been no change. As mitosis is a component of cell replication, no mitosis has taken place if we reach the same number of cells as when we began.
