b. She draws branches for gymnosperms at the beginning of her tree.
c. She draws branches for simple land plants after the branches for flowering plants.
f. She draws a branch for gymnosperms after the branches for vascular plants.
What is the Gretta's organization of her phylogenetic tree?Gretta's organization of her phylogenetic tree likely follows the current understanding of plant evolution. Gymnosperms are considered to be one of the earliest groups of plants to evolve and are therefore placed at the beginning of the tree.
Flowering plants, also known as angiosperms, are a more recent group of plants that evolved after gymnosperms and are placed after gymnosperms in the tree. Simple land plants, which include nonvascular plants, are thought to have evolved before vascular plants, and are therefore placed after flowering plants. Vascular plants, which include both gymnosperms and angiosperms, are a diverse group of plants that evolved a system of tubes for transporting water and nutrients throughout the plant. Gymnosperms and angiosperms are placed in separate branches of the tree after the branches for simple land plants.

What is a non-example of edge effect?
Explanation:
A non-example of edge effect would be a homogeneous, single ecosystem without any transition zone or boundary. Edge effect refers to the changes that occur at the boundary between two different ecosystems, such as a forest and a grassland or a beach and a dune system. Therefore, if there is no distinct boundary between two different ecosystems, or if there is only a single ecosystem, then there would be no edge effect.

(I WILL MARK BRAINLIEST) After reading the excerpt, describe what happened in 1977 and 1984 as it relates to competitive advantage.
"In 1977, there was a severe drought on Daphne Major. All the vegetation on the island was affected. Most of the finches died. The birds quickly ate all the small, soft seeds. In time, only the large, tough seeds remained. During this drought, when food was scarce, the small finches with smaller beaks died. The finches with larger, stronger beaks that could eat the harder seeds survived. The Grants found that the offspring of the birds that survived the 1977 drought tended to be larger and have bigger beaks. Now, in 1984 1985, the Grants studied the birds during a season with heavy rainfall. They found that during the year with heavy rainfall, the birds that were best able to consume the small, soft seeds survived and reproduced, while the birds that could only eat the heavier seeds died. Those birds then produced offspring that had beaks that were suitable for eating small, soft seeds. The birds that had the beaks that were most useful for consuming the type of seed that was most abundant in any given season had competitive advantage over other birds. Species with a competitive advantage in a given environment have a greater chance of surviving and reproducing. The Grants found that adaptations can occur within a few generations."
Answer:
The example of the finches on Daphne Major island illustrates the concept of competitive advantage, which refers to a species' ability to thrive and reproduce in a particular environment compared to other species. In the case of the finches, those with beaks that were best suited for the type of seed available in each season had a competitive advantage over other birds. During the 1977 drought, only the large, tough seeds remained, and the finches with larger, stronger beaks had a competitive advantage over those with smaller beaks, allowing them to survive and pass on their advantageous traits to their offspring. In 1984-1985, during a season of heavy rainfall, the finches with beaks suitable for consuming small, soft seeds had a competitive advantage. The finches' ability to adapt to the changing environment and exploit the available food sources gave them a competitive advantage and enabled their species to survive and reproduce. Understanding the concept of competitive advantage is crucial to understanding how species evolve and adapt over time.
The example of the finches on Daphne Major island exemplifies the idea of competitive advantage, which refers to a species' ability to thrive and reproduce in a specific environment relative to other species. In the instance of the finches, those with beaks best suited to the type of seed available at the time had a competitive advantage over other birds. Only the large, tough seeds survived the 1977 drought, and the finches with larger, stronger beaks had a competitive advantage over those with smaller beaks, enabling them to survive and pass on their advantageous traits to their offspring. During a period of heavy rainfall in 1984-1985, finches with beaks suited for consuming small, soft seeds had a competitive advantage.

Kynze collected 18 ten-dollar bills while selling tickets to the for fair she gave 1/6 of the bills to the fairs office
and kept the rest. How much money did she keep? $
Answer: Kynze kept $150 from the money she collected from selling tickets to the fair
Explanation:
Kynze collected 18 ten-dollar bills, which means she collected a total of:
18 x $10 = $180
Next, she gave 1/6 of the bills to the fair's office, which is the same as dividing the total number of bills by 6 and taking one of those parts:
18 / 6 = 3
So Kynze gave 3 ten-dollar bills to the fair's office, which is equivalent to:
3 x $10 = $30
Therefore, Kynze kept the remaining 15 ten-dollar bills for herself, which is equivalent to:
15 x $10 = $150
Therefore, Kynze kept $150 from the money she collected from selling tickets to the fair.
Which law?
Your teammate pushes you on the hovercraft. You accelerate to
a thrilling speed.
Another person joins you on the hovercraft. Your teammate
pushes you just as hard, but this time the ride is less exciting.
This scenario can be explained by Newton's second law of motion, which states that the force acting on an object is equal to its mass multiplied by its acceleration (F = ma).
Scenarios:
In the first scenario, there was only one person on the hovercraft, so the force from the teammate's push caused a greater acceleration (a = F/m) and resulted in a more thrilling ride.
In the second scenario, there were two people on the hovercraft, so the total mass was greater. Even though the teammate pushed with the same force as before, the acceleration was less (a = F/m) because the mass was greater, resulting in a less exciting ride.
What is motion?
Motion refers to the change in position of an object over time with respect to a reference point. It is typically described in terms of the object's displacement, velocity, and acceleration. Displacement refers to the change in position of the object from its initial position to its final position, while velocity refers to the rate of change of displacement over time. Acceleration refers to the rate of change of velocity over time, and can be positive (speeding up), negative (slowing down), or zero (constant velocity).

what is process of reproduction
It is through biological reproduction that new, unique species are produced. The two types of reproduction are sexual and asexual.
Two parents contribute genetic material during sexual reproduction to create unique offspring1. Gametes (sperm and egg) from two parents combine during sexual reproduction to create a zygote. After that, the zygote goes through cell division and differentiation to develop into an embryo.
A zygote is what?
A zygote is a eukaryotic cell created when two gametes fertilize one another. To put it another way, it is the first cell created when two gamete cells (egg and sperm) unite during sexual reproduction. The zygote has all the genetic material needed to develop into a new person.
Asexual reproduction involves the creation of genetically identical offspring by a single parent. Many processes, including binary fission, budding, fragmentation, and vegetative propagation, can lead to asexual reproduction.
Describe binary fission.
Asexual reproduction known as binary fission occurs when a single creature splits into two separate organisms4. Bacteria and other prokaryotic species frequently exhibit this process.
