and during reproduction. This process gives rise to the production of four
unique daughter cells.
Prophase 1 and metaphase 1 are the major events in meiosis responsible for
new genetic combinations and the creation of unique daughter cells.

Plants are eukaryotic, multicellular, have cellulose walls and prepare their own food.
Answer of the questionsThey 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.

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.

An invasive or introduced species is any plant, fungus, animal, etc. species that meet two criteria:
The species does not naturally belong to that habitat.The species was introduced by humans.The fern can be classified as an invasive or introduced species because this fern is not native to that area, and it is being introduced by the people designing the hotel.
Moreover, this species can have negative effects on the new species discovered and on other native local species.

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.

¿Qué es el oído y qué hace?
El oído consta de tres partes diferentes, que funcionan conjuntamente para captar sonidos y transmitírselos al cerebro: el oído externo, el oído medio y el oído interno.
El oído externo
El oído externo está formado por el pabellón auditivo (también conocido como "pabellón auricular" o "pabellón de la oreja") y el conducto auditivo. Los pabellones auditivos son las partes visibles que tenemos a ambos lados de la cabeza y están compuestos por cartílago duro cubierto de piel. La principal función del pabellón auditivo consiste en captar sonidos y conducirlos hacia el conducto auditivo, que conecta con el oído medio. Las glándulas de la piel que recubren el interior del conducto auditivo fabrican cera o cerumen, que protege este conducto, eliminado la suciedad y ayudando a prevenir posibles infecciones.
El oído medio
El oído medio es una cavidad llena de aire que transforma las ondas sonoras en vibraciones y las transmite al oído interno. El oído medio está separado del externo por el tímpano (o membrana timpánica), una fina lámina de tejido que va de lado a lado del conducto auditivo y que está fuertemente tensada sobre él. Los sonidos golpean el tímpano, haciendo que se mueva.

Answers
The frequency of P will increase and the frequency of p will decrease.
The frequency of P will increase and the frequency of p will decrease if the insects clearly favor purple flowers over white ones.What happens to the frequencies of P and p in the population if the insects clearly favor purple flowers over white ones?
The frequency of P and p alleles in the population changes in response to natural selection. When insects favor purple flowers, they will likely visit more purple flowers than white ones.
As a result, the purple flower will receive more pollen from the insects than the white flower. In the next generation, the frequency of the P allele will increase and the frequency of the p allele will decrease since more offspring will have the P allele.
As a result, the population will have a higher proportion of purple flowers in the future. According to natural selection, the frequency of an allele increases if it improves the probability of survival and reproduction of the organism carrying it.
The allele that increases the organism's likelihood of survival and reproduction is chosen as the favored allele. In the given scenario, the favored allele is the P allele.

Answer:
The frequency of P will increase and the frequency of p will decrease.
Explanation:
If the insects clearly favor purple flowers over white ones, then the purple flowers will be more likely to be pollinated than the white flowers. This means that the purple flowers will produce more offspring than the white flowers, which will increase the frequency of the P allele in the population. At the same time, the white flowers will produce fewer offspring, which will decrease the frequency of the p allele in the population. Over time, this could lead to a higher frequency of the P allele and a lower frequency of the p allele in the population.
