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.

Four of the six kingdoms are compromised of organisms that contain
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.
Regarding the other options:
Both cell types, eukaryotes and prokaryotes, have ribosomes, genetic material and cell membrane.
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.

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.

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.

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.
