How many sugar phospha te backbones are in one strand of DNA?
Answer: Two
Explanation: In double-stranded DNA, the molecular double-helix shape is formed by two linear sugar-phosphate backbones that run opposite each other and twist together in a helical shape. The sugar-phosphate backbone is negatively charged and hydrophilic, which allows the DNA backbone to form bonds with water.
Compare the Three General patterns of population dispersion
Answer:
Explanation:
There is Uniform dispersion, where the individuals in a population are more or less evenly distributed. Also, there is Random dispersion in which individuals are distributed randomly, meaning there is no plan. Finally, there is Clumped dispersion, where individuals are just distributed in groups. Hope it helps x.
The three general patterns of population dispersion are as follows:
Clumped: Variance/mean is greater than 1.Random: Variance/mean is equal to 1. Spaced: Variance/mean is less than 1. What is Population dispersion?Population dispersion may be characterized as the process of spatial distribution and arrangement at any particular moment of the individuals of a certain species. It generally governs the spacing of individuals with the environment at a given time.
Clumped type is the most common type due to attraction. In a random type, the facts of attraction or repulsion do not favor. Spaced type of population dispersion is also known as uniform.
It is generally present in artificial ecosystems or cultivation. Uniform patterns of dispersion are generally a result of interactions between individuals like competition and territoriality.
Therefore, the three general patterns of population dispersion are well described above.

How many years might primary succession take with medium amounts of rainfall and temperature? Explain why HELPP PLEASE HELP
Answer:
The primary succession process can take hundreds of years to happen, even in medium amounts of rain and temperature.
Explanation:
The primary succession occurs when a community of plants begins to sprout in areas that have never been occupied by any type of living being. The primary succession occurs, for example, with the sprouting of vegetables in rocky outcrops. These plant species are known as primary species and although they are able to survive, these environments offer few resources for the development of living things. Generally, it takes hundreds and even thousands of years for primary succession to occur, even in environments with average temperature and precipitation.
Primary succession takes more than 100 years to occupy with medium amounts of rainfall and temperature.
What do you mean by Succession?Succession is the gradual and continuous replacement of one community by another community over a long period of time.
Primary succession is the succession that is starting for the very first time, where there is no life that existed before. It usually started from a bare area. Examples of primary succession include Igneous rock, Glaciers, etc.
It is associated with the occurrence of new sprouted life forms arising in a given area. This activity requires more than 100 years when there is a sufficient amount of rainfall and temperature is there.
Therefore, Primary succession takes more than 100 years to occupy with medium amounts of rainfall and temperature.

Which kingdoms contain organisms that have cell walls?
The function of cell wall is to provide protection. The kingdoms which have cell walls are fungi and plantae.
What is the function of cell wall ?The cell wall provides the protection against the mechanical stress and the pressure that a cell membrane can not handle.
Cell wall is majorly present for the purpose of protection to the species and these species tend to be delicate and tend to be in more danger.
Cell wall of fungi is made up of chitin and it is polysaccharide having the amino glycosidic linkages.
Cell wall of plants is made up of polysaccharides as well where the cellulose is present in chains.
Cellulose provides the tensile strength and this amino glycosidic linkages tend to provide strong skeletal structures in order to provide protection to the specimen.
Therefore only plantae and fungi have the cell walls.

Explanation:
A scientist studying the effects of radiation on DNA performs an experiment in which she exposes a sequence of nitrogen bases found in DNA to radiation. The DNA before and after the radiation is shown below.
Use the evidence to determine whether a mutation has occurred, and if so, interpret that mutation in the answer sheet provided
Before Exposure: ATCGTCA; After Exposure: ATTCGTCA
A. No mutation has occurred to the DNA sequence.
B. A nitrogen base has been deleted from the DNA molecule.
C. A nitrogen base has replaced another nitrogen base in the DNA molecule.
D. A nitrogen base has been added to the DNA molecule.
Answer:
D. A nitrogen base has been added to the DNA molecule.
Explanation:
You can see that the sequence for the nitrogen bases are in the exact same order after the exposure, this rules out A. You can count how many bases there are, 7 before and 8 after so it cannot be B. Lastly, given that they are in the same order as were before and that a base has been added, you can see that no bases were replaced (so not C) and that D is your answer.
