In tomato plants, red fruit (R) is dominant to yellow fruit (r). Interpret the Punnett square below, which shows a cross between a heterozygous red plant and a yellow plant. Include the possible genotypes and corresponding phenotypes.
Answers
Answer:
2/4 or 50% are red-fruited (Rr) and 2/4 are 50% are yellow-fruited (rr)
Explanation:
brainliest pls
Dominant traits are the allele that is expressed in purebred and heterozygous condition. 50% of progenies are red and the other 50 % are yellow.
What is a Punnett square?A Punnett square is a diagrammatical representation of the cross between the parents that portrays the alleles in the square boxes. It is used to conclude about the genotype and the phenotype.
From the Punnett square, it can be concluded that:
The phenotype and the genotype of the offspring, red: yellow = 1:1
Therefore, the red plants and yellow plants are in a ratio of 1:1.

Hi!!
So Rosa eats a peanut butter sandwich, which gives her protein and starch, right? She also goes on a run and breathes normally, which gives her a good amount of oxygen. Based on this, we can conclude...
1. Cells need the protein and starch to make energy.
A cell uses proteins to keep itself alive and functioning. Because the proteins keep the cell working, the cell can change the starch into sugars, which in turn becomes food for the cells. The sugar is used to keep Rosa running.
2. The cell also needs oxygen.
The cell gets oxygen through the bloodstream. When Rosa breathes well, she is making sure that she is providing her body with enough oxygen to run.
Rosa's body systems give the cells protein, starch, and oxygen, which allows the cells to function. This, in turn, allows Rosa to run and play without worry.

a two-paragraph report on flower reproduction
Answers
Answer:
Flowering plants reproduce sexually through a process called pollination. The flowers contain male sex organs called stamens and female sex organs called pistils. ... Cross-pollination happens when the wind or animals move pollen from one plant to fertilize the ovules on a different plant. The primary purpose of a flower is reproduction. Since the flowers are the reproductive organs of plant, they mediate the joining of the sperm, contained within pollen, to the ovules — contained in the ovary. Pollination is the movement of pollen from the anthers to the stigma.
Explanation:
Answer:
Alternation of generations occurs in plants, where the sporophyte phase is succeeded by the gametophyte phase. The life cycle of a flowering plant. The angiosperms were the last of the seed plant groups to evolve, appearing over 100 million years ago during the middle of the Age of Dinosaurs. Reproductive parts of the flower are the stamen and carpel. Often the carpel is referred to as the pistil, the female parts collectively termed the gynoecium. The androecium is the individual units of the androecium are the stamens, which consist of a filament that supports the anther.
Pollen Pollen grains, from the greek palynos for dust or pollen, contains the male gametophyte phase of the plant. The outer part of the pollen is the exine, which is composed of a complex polysaccharide, sporopollenin. Hypothesized steps in the evolution of the carpel. Nonvascular plants, the mosses, and liverworts have the gametophyte phase dominant. Vascular plants show a progression of increasing sporophyte dominance from the ferns and "fern allies" to angiosperms.

Explanation:
just did the test
U-shaped valley include action of glaciers, form in mountainous region, and wider as well as more gradual base. V-shaped valley is formed by strong streams, erosive, and deeper than they are wide.
What is a valley?Valleys are low-lying areas of land that have been eroded and washed away by the combined elements of gravity, water, and ice. Some dangle, while others are feeble. They are all in the shape of a "U" or "V."
Humongous frames of snow and ice slowly creep downhill, seeking the least resistance. As the glaciers seep, they start picking up rocks and grind away at the valley floor and sides, forming a "U" and transforming the "V" into a "U." When the glacier melts, it leaves a U-shaped valley where the snow flowed.
U-shaped valleys are formed by glaciers, have a wider and more gradual base, and are found in mountainous areas. Strong, erosive streams form a V-shaped valley that is deeper than it is wide.
Thus, V-shaped valley include options 1, 2, and 4. U-shaped valley is 3, 5, and 6.

What evidence have you discovered to explain how cells are organized in the body, similar to the way dots in pointillism art is organized.
Answers
Answer:
I'd have to say that cells are grouped by function and specialty. Many of the same type of cell are joined in a common task. Muscle cells are joined to form a specific task. Different cells in the body form into different organs and structures to form the whole body.
In art, pointillism uses dots of various sizes and colors. These dots are arranged so as to produce a specific visual effect. The entire work is composed of many individual points to form the whole picture.
In this way, we can equate the body's various cell to dots in a work of pointillism.

What is the Punnett Square?The Punnett Square may be characterized as a kind of table in which all of the plausible consequences for a genetic cross between two individuals with known genotypes are systematically demonstrated.
According to the question, there is a homozygous dominant genotype of one parent when crossed with the heterozygous genotype of other parents, then the genotypes of resultant offspring must carry at least one dominant allele which governs the phenotype of the entire offspring.

Environmental change has a change or the disturbance of the climate which has been most often causes due to the human behavior, human activity or the natural ecological processes.
Environmental change has been consists many factors, such as the natural disaster, human interferences, or animal interactions. It has been also included physical change. Environmental change can also refers to the long-term shift in the temperature and weather patterns. These shifts may be the natural, such as through variations in the solar system.
In environmental change natural systems transform the sun's energy into living matter and cause changes by cycling material through geological, biological, oceanic and atmospheric processes. So environmental change has serious issue to our human society.

Passage
A group of students is studying the types of plants that grow in a field next to the school. The field is mowed regularly, but it does not get any water other than rainfall. The field has several kinds of plants that are typically found in a grassland ecosystem. But it has none of the plants found in a nearby forest ecosystem.
Answers
Answer:
The reason why the ecosystem has many different kinds of plants is because of the soil, or the environment around them. Also, some biotic factors like animals or humans could be the reason. The humans may have planted seeds there, and probably some abiotic things like soil could also be the reason why. The plants that grow there receive a lot of rain, or the limiting factor is the rain, and the type of plants that grow there don't need much water to survive.
