5. Based on your knowledge of flowers, why do you think most flowers are bright in color?
The plant is made up of root and shoot structures that contain parts that enable the plant to grow and manufacture its food.
The structure and function of plantsThe structure of plants is made up of tissues such as:
phloemstomaxylemguard cellsdermalground andvascular.The three characteristics that all species being to the plant kingdom have in common are:
They are non-motile,They make their food hence are called autographs; andTheir cell walls are made sturdy by a material called celluloseThe tropical plants have more stomata than the desert plants. This helps the desert plants to reduce water loss.
Some defects occur when there is damage to the vascular tissues such as the xylem( plant will not be able to transport water from the soil through roots to leaves) and phloem (nutrients produced during photosynthesis will not be able to reach every part of the plant body).
The dermal tissue of plants and the human skin performs protective roles to the underlying tissue organs.
A plant won't be able to survive because it won't absorb water and nutrients from the soil and transport it upwards to all the parts of the plant.
Flowering reproduction in plants takes place through the following steps:
Pollen is carried by insects or blown by the wind from one flower to another. This process is called pollination. Pollen reaches the new flower and travels to the ovary where it fertilises egg cells (ovules) to make seeds. This is fertilisation.Flowers benefit other organisms in our environment by creating more carbon dioxide-absorbing and oxygen-radiating plants.
The flowers contain male reproductive organs called stamens and female reproductive organs called pistils.
The process of seed development begins with double fertilization and involves the fusion of the egg and sperm nuclei into a zygote.
Most flowers are bright in color because they are like advertisement signs for pollinators.

Why does DNA need to replicate in our cells
Here is a Answer to your question:
DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules. Replication is an essential process because, whenever a cell divides, the two new daughter cells must contain the same genetic information, or DNA, as the parent cell.
I am sorry if this was not helpful
Hope this was helpful
DNA also known as Deoxyribonucleic Acid is a double stranded macromolecule. The two strands of DNA are complementary to each other. For replication, the DNA double helix opens at one end, making the two strands free to which new strands begin to form and the process continues in a sequence for the whole length of the DNA.

In Shakespeare's most well-known tragedy, two young star-crossed lovers’ deaths ultimately reconcile their feuding families. This straightforward adaptation mixing contemporary and classical language emphasizes story and character rather than the poetry. Master director and acclaimed playwright Jon Jory has reimagined the classic tale to serve as an early introduction for younger audiences and actors that allows easy involvement. Inventive yet faithful, this adaptation will inspire actors and audiences alike to revisit Shakespeare’s original texts. Gender-neutral casting is encouraged and doubling is possible. Simple stage allows for a fluid and forward moving production.
Procedure:

how both genetic and environmental factors can affect paint color variation in california rabbits
Answer:
Coat color in rabbits is inherited as a series of multiple alleles.
Explanation:
This means that there can be more than just 2 alleles for a single gene. In the case of coat color in rabbits, there are four alleles, and each one is expressed with a different phenotype.
The genetic factors that can affect paint color variation in California rabbits are based on the several different genes that are inherited from their parents. It includes color base, color density, pattern, an extension of dark pigment, spotting, silvering, etc.
What are the genes that are responsible for color variations?The genes that are responsible for color variations are as follows:
Gene A controls the pattern of the coat.Gene B controls the base of coat color.Gene D controls the density of the coat color.Apart from these direct genes, several other genes are also responsible for causing variations in paint color in Rabit. The effect of environmental factors remains the same for every species regardless of competition, and other limited resources. These environmental factors govern the alteration gradually over a long period of time to stimulate some observable responses in the organisms.
Therefore, the genetic and environmental factors that can affect paint color variation in California rabbits are well described above.
