Compare the Three General patterns of population dispersion

Answers

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.

Which kingdoms contain organisms that have cell walls?

Answers

The plantae,Protista, eubacteria kingdom. I think it’s just the 3.

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.

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.

Answers

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.

With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest, mutations of DNA sequences of the frog genome that are inherited by offspring It is estimated by a wide body of scientists that in recent decades we have begun another mass extinction event on Earth. Amphibians in particular have been in decline, sometimes due to climate change, and they therefore provide a possible early sign of dramatic biodiversity change to come. With respect to climate change and natural selection acting upon a population of one species of frog in a tropical rain forest, mutations of DNA sequences of the frog genome that are inherited by offspring may have no effect at all, be beneficial, or be harmful. will primarily be harmful. will only speed the decline and extinction of the species. could either be beneficial or harmful.

Answers

Answer:

be beneficial.

Explanation:

Mutations of DNA sequences of the frog genome that are inherited by offspring will be beneficial for the frog because this mutation in the genetic makeup of frog provides resistance in this new environmental conditions. This mutation occurs due to the exposure of cell's DNA to the environmental factor which gives benefit to the organisms to survive different condition which can't tolerate by their parents so this mutation is beneficial for that offspring of frog.
