B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules.
C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Answer:
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production
Explanation:
During transcription, RNA polymerase uses DNA as a template to create a new molecule of mRNA via complementary base pairing
A) tRNA with anticodons is carrying amino acids to the ribosomes. - this is not evidence of transcription but is instead evidence of translation
B) DNA polymerase is using both strands of DNA to produce multiple RNA molecules. - this is false, DNA polymerase is the enzyme that performs DNA replication not transcription.
C) Ribosomes are reading mRNA molecules three nucleotides at a time to synthesis proteins - this is not evidence of transcription but is instead evidence of translation
D) RNA polymerase is using a single strand of the DNA molecule as a template for mRNA production - this accurately describes the process of transcription.

Can a purine pair with a purine?
Answer:
A always pairs with T and C always pairs with G. A and G are purines, meaning that they have two rings, while T and C are pyrimidines, meaning they have one ring. Due to the Watson and Crick model, the width of DNA is constant, meaning that there must be a consistant width in each base pairing. As a result, only a purine can pair with a pyrimidine, giving each base pairing a total of 3 rings.

Explain how seeds travel. Be sure to give examles to support your explantion psb quic
Answer:
Wind, Water, Animals, and Fire.
Explanation:
Wind moves seeds from one place to another. When the seed gets into the air, it gets pushed by wind to another place. Water moves seeds when seeds fall into water and the water moves the seed downstream, or the water evaporates. Seeds get moved by Animals when, for example, a bird eats seeds then flies to another location, and poops out the seeds. Seeds also get moved by Fire when a forest fire erupts and the seeds fall to the ground after the fire dissipates.

Alice wants to find out whether her pet gecko finds its prey based on vision. She thinks that her gecko will more easily see the colored crickets. She follows these steps:
get 10 similar crickets from the pet store
tag 5 of the crickets by putting a tiny dab of bright coloring on their backs
release all 10 crickets into the terrarium with the gecko at the same time
after several hours, record the number of tagged and non-tagged crickets still alive in the terrarium
After several hours, Alice notes that only 4 non-tagged crickets were still alive in the terrarium. No tagged crickets were observed. She concludes that her gecko uses mostly its vision to capture and eat its prey.
What is another possible explanation for these results?
She relays more on her vision than her other senses so you could assume she has good eye sight or something.
what is the Atomic Number of a neutral atom that has 5 neutrons and 4 electrons
The atomic number, z, is the number of protons. Assuming that this is an electrically neutral atom -the number of protons equals the number of electrons-, we can say that the atomic number is 4.
----------------------------------------
The representation of an element includes a superior number that indicates the massic number, and an inferior number that indicates the atomic number. We need to know that every atom is identified by its number of protons and neutrons. So,
Representation ⇒ ᵃ X ₀
Where
• X is the element
• a is representing the massic number, which is defined as the sum of the number of protons and the number of neutrons.
• z is the atomic number, which is the number of protons ⇒ represented as
0 above
In electrically neutral atoms, the number of protons equals the number of electrons. This means that the atomic number also indicates the number of electrons.
• We will call n to the number of neutrons, which equals a - z
When protons, neutrons, and electrons get together to form an atom, they lose part of their mass as energy. This is why the atomic weight is slightly inferior to the sum of masses.
So, what you need to know is that
• Nº of protons = Atomic number → z
• Nº of neutrons = Massic number - Atomic number → n = a - z
• Nº of Electrons = Nº of protons = Atomic number → z
Let us analyze the carbon example.
Element representation ⇒ ¹⁴ C ₆
• Massic number = 14
• Atomic number = 6
So, from this information we can assume that
• Nº of protons = Atomic number → 6
• Nº of neutrons = Massic number - Atomic number → 14 - 6 = 8
• Nº of Electrons = Nº of protons = Atomic number → 6
In the exposed example, we have an element, let us name it X with 5 netrons and 4 electrons. And we need to say what is the atomic number, z. In this example we do not need to do perform any calculations, because we already know that the atomic number = number of protons = number of electrons, so
• Nº of neutrons = Massic number - Atomic number → 5
• Nº of Electrons = Nº of protons = Atomic number → 4
from this information we can assume that the massic number is 9, because the massic number = number of protons + number of neutrons.

Write a scientific explanation detailing the transfer of energy through an ecosystem. Using the energy pyramid below, determine how much energy will be transferred to each level of the pyramid if the producers have 1 million kilocalories, and explain where the rest of the energy will go.
Answer:
I cannot do math but i can tell you that less than 1 percentage of eneegy is transfered from the primary plant down the pyramid
The amount of energy that will be transferred to each level of the pyramid if the producers have 1 million kilocalories is as follows:
Producers = 1000000 kcal.Primary consumers = 100000 kcal.Secondary consumers = 10000 kcal.Tertiary consumers = 1000 kcal. What is an ecosystem?An ecosystem may be defined as a place or an area where individuals of different species live together and interact with one another for the purpose of food, shelter, and space.
According to the 10% law given by Lindemann, only 10% of energy gets transferred from one trophic level to the next while the remaining energy is utilized for various life processes of the organisms and some are lost as heat.
The left 90% of the energy is utilized in order to live, grow, reproduce, etc. While some energy may also be lost as heat in the environment.
Therefore, the amount of energy that will be transferred to each level of the pyramid if the producers have 1 million kilocalories is well described above.

Photosynthesis and cellular respiration both involve the use and release of gases. Which statement correctly identifies the role of gases in the two processes
Answer:
You have no options for me to choose from, but I'm going to make a wordy response anyway. The answer is stated below:
Explanation:
Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.
Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.
What is photosynthesis?Photosynthesis uses carbon dioxide and releases oxygen and cellular respiration uses oxygen and release carbon dioxide.
Photosynthesis is the process in which green plants prepare their own food in the presence of sunlight and light energy is converted into chemical energy by the process of cellular respiration.
The process of photosynthesis takes place in green plants only due to presence of chlorophyll and materials such as sunlight, water, carbon dioxide is required for the process of photosynthesis.
The equation of photosynthesis is represented below:
6CO2+ 6H2O - C6H12O6 + 6O2
The process of food manufacturing in plant is done through photosynthesis and the plants are known as autotrophs as they are the producers.
In the process of photosynthesis the reactant have 6 carbon dioxide molecules and six water molecules, and light energy converted into chemical energy due to presence of chlorophyll.
Therefore, Cellular respiration uses carbon dioxide and releases oxygen, while photosynthesis uses oxygen and releases carbon dioxide.

1. A volcanic eruption levels the land in the surrounding area,
covering everything with ash and killing almost all living things. This is
classified as a
limiting factor.
2. As the population of elks in a forest increases, the decreasing
availability of their food source, aspen and willow leaves, acts as a
limiting factor.
3. Part of a forest is clear-cut to make room for new buildings and
roads as part of a housing development. This decreases the available
habitat for all species, making it a
limiting factor.
The limiting factors for these scenarios are density dependant or density-independent.
The growth or decrease of a population depends on factors that can or cannot be related to the number of inhabitants that the population has.
Density dependant limiting factors: the growth rate of a population changes due to the increase in a population's density, that is to say, the number of inhabitants, has a direct impact on the growth or decrease of this population.
Density Independent limiting factors: the growth rate of a population changes due to factors that are not related to the population itself. In other words, they are external factors, such as a volcanic eruption, that affect the rate.
In conclusion, a volcanic eruption covering everything in ash and killing almost all living things is a density-independent limiting factor. The increase in the population of elks and the decrease in their food source is a density dependant limiting factor, which makes elks compete for food. Lastly, part of a forest being clear cut to make room for buildings, and decreasing the available habitat for species is a density-independent limiting factor.

eukaryotic cells. Which structure in a cell would give you the BEST
evidence that the cell is eukaryotic? *
O Ribosome
O Genetic material
O
Nucleus
O Cell membrane
Answer:
The best evidence that a cell is eukaryotic is the presence of the cell structure called the nucleus.
Explanation:
The most significant difference between eukaryotic and prokaryotic cells is that the former have a nucleus, where they store genetic information in the form of DNA.
The nucleus of eukaryotic cells occupies approximately the center of the cell and is a structure associated with the endomembrane system. Its function is to control cell activity, and its genetic material is duplicated before cell division.
In prokaryotic cells, in the absence of a nucleus, the genetic material is dispersed in the cellular cytoplasm.
