Answers

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

Answer of the questions

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.

Answer: im answering the questions the other guy didnt answer ( im not an expert by any means to comment if im wrong and ill edit

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.

In bacteria, translation of the mRNA begins near the 5' end of the mRNA molecule, when a(n) binds to that site.

Answers

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.

you come back the next year to look at the flowers from the next generation of plants. you find 50 plants. if this population is in hardy-weinberg equilibrium, how many plants with white flowers would you expect to find?

Answers

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.

Note: This question is incomplete because there is missing information. However, you can answer with a practical example.

The volumeter is a device that can be used to measure the changes in volume represented by the movement of an air bubble in a capillary tube.

In consequence, this dispositive enables the detection of small changes in volume that result from the exchange of gases (i.e., oxygen and carbon dioxide) during plant photosynthesis or respiration.

Which two organisms are most closely related, based on the tree above?
ray-finned fishes and sharks
rodents and primates
dinosaurs and crocodiles
dinosaurs and birds

Answers

Answer:

dinosaurs and birds

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

Why are organisms related?

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.
