The celery is dicot in nature.
What are the characteristics of dicots plants?The dicotyledons, also known as dicots, are one of the two groups into which all the flowering plants were formerly divided. There are around 200,000 species within this group.
Most common garden plants, shrubs and trees, and broad-leafed flowering plants such as magnolias, roses, geraniums, and hollyhocks are dicots.
Dicots get their names from having two cotyledons instead of one. Dicot flower parts come in multiples of 4 or 5. Count the petals and identify whether they are multiples of 4 or 5. Dicot leafs have veins that are scatter or “netted.

Due to its location, Hawaii does not have very many land birds. The Hawaiian honeycreepers are a favorite for many ornithologists. There are over 50 species of honeycreepers that can all be traced back to one ancestor. The level of diversity in an ecosystem can be determined by the frequency of speciation and extinction.
Describe speciation and identify two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to speciation.
If the Hawaiian honeycreepers became extinct, explain how the newly available niches could lead to speciation.
Answer:
In speciation, organisms evolved with the passage of time.
Explanation:
Speciation is the evolutionary process in which populations of species evolve with the passage of time to become different species from the original one. Temporal isolation and gametic isolation are two possible prezygotic barriers of the Hawaiian honeycreepers that contribute to occur speciation. The newly available niches could lead to speciation of that organisms that tolerate the Hawaiian climatic conditions when the extinction of Hawaiian honeycreepers occurs. The new organisms used the available resources such as food and space etc and increase its population.

Do the plants and animals on a farm make up an ecosystem? Why or why not?
Answer:
Yes they do
Explanation:
Animals and plants make up a ecosystem because the animals feed off the plants and the animals feed off of other animals.
Answer:
All living things in ecosystems are part of a food chain. A food chain is how energy is passed between things. farms are ecosystems. Farmers work with crops, animals, soils, and the weather to grow our food.
Explanation:
Compare the two Food Web. Which ecosystem would be more likely to survive if a disease killed the grass?
a The forest ecosystem, because the animals would be able to eat other organisms.

1. You have set up a cell-free transcription system in a test tube. By mixing DNA, RNA polymerase, sigma factors, ribonucleotides and other essential substances you are able to make mRNAs identical to those made under a variety of conditions in the cells from which these components were isolated. What would happen if you were able to remove the sigma factor first added to the tube and replace it with another sigma factor
Answer:
Different messenger RNAs (mRNAs) would have been produced
Explanation:
Sigma factors are protein subunits that form bacterial RNA polymerases and they are responsible to initiate RNA synthesis. The number of sigma factors is variable between different bacterial species. For example, Escherichia coli contains seven sigma factors, while Bacillus subtilis has at least 17 sigma factors, which control the transcription of different genes. These factors determine the specificity of the RNA polymerase to the target gene promoter regions and then control transcription initiation.

Why would you expect to find a great deal of
parenchyma tissue in the roots of plants such as the

Mammals really spread and diversified during the Cenozoic era. So, the correct option is D.
What was Cenozoic era?The Cenozoic Era is defined as the third of the major eras in Earth's history that began about 66 million years ago and extends to the present. This epoch was the interval of time during which the continents assumed their modern configurations and geographic positions during which the Earth's flora and fauna evolved towards the present.
The Cenozoic Era is called the "Age of the Mammals", while the typical landscapes of North America began to develop during the Cenozoic. Birds and mammals rose to prominence after the extinction of giant reptiles.
Thus, Mammals really spread and diversified during the Cenozoic era. So, the correct option is D.

When it is summer in the U.S, why is it winter in South America?
Answer:
the suns on the other side of the earth at the time
Explanation:
hope it helps :)
Answer:
The Earth is tilted at an angle of about 23 degrees, which means that depending on where Earth is on its orbit, one pole will be getting more hours of light (summer) and one will be dark (winter).
Explanation:
Also, the earth is tilted on it's axis so more direct rays of sunlight hit the southern hemisphere making it summer in that hemisphere while it is winter in the northern hemisphere. Six months later, this reverses, and more direct rays hit the northern hemisphere. That's why it's summer here while it's winter there.
The earth's distance from the sun has nothing to do with it. It's all about the axial tilt.

DNA is copied during the S Phase of Interphase. Why do cells copy the DNA?
Answer:
During mitosis, a eukaryotic cell undergoes a carefully coordinated nuclear division that results in the formation of two genetically identical daughter cells. Then, at a critical point during interphase (called the S phase), the cell duplicates its chromosomes and ensures its systems are ready for cell division.

What is one of the biomolecules for which nitrogen is needed (hint: they help build muscles)?
One of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.
What is the significance of the nitrogen in the protein?Proteins play many important roles in the body, including building and repairing tissues, and nitrogen is a critical component of proteins, as it is incorporated into the molecule as a part of the amino acids. Without nitrogen, proteins would not be able to form and perform their many important functions so a diet that is rich in protein is important for athletes and bodybuilders to build and repair muscle tissue.
As a result, of the biomolecules for which nitrogen is needed and that build muscles are the proteins, and the nitrogen is also found in the DNA and RNA that are present in the cells.
