Answer:

It is increasing rapidly.

here is your answer

don't forget to give some hearts

Explanation:

The statement which is true about the population in this graph is that it is increasing rapidly. Thus, the correct option for this question is B.

A population may be defined as a group of individuals belonging to the same species living in the same area at a definite time. The size, density, birth rate, death rate, and abundance, are some characteristics of a population. These characteristics of the population are known as demographic factors.

According to the context of this question, the axis of the graph is increasing very rapidly. It determines the rate of population towards rapid growth. The growth of any population depends on various factors such as space, food, resources, mating partners, availability, etc.

Therefore, the statement which is true about the population in this graph is that it is increasing rapidly. Thus, the correct option for this question is B.

Answer:

Explanation:

Crossing over and independent assortment in gametes (sex cells) can lead to genetic variation in the DNA of these gametes and lead to offspring looking different from their parents. Crossing over is the exchange of DNA between a pair of homologous chromsomes (the mom and the dad) which results in recombinant chromsomes that have new combinations of genes. Independent assortment refers to the lining up of chromsoomes along the metaphase plate in meiosis 1, and this can lead to different combinations of gametes.

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:

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.

Photosynthesis???????

Answer: No. Although many proteins check the DNA for damage or errors, damaged regions can still be replicated. This may result in gene alterations and serious complications for the organism.

Explanation:

No, replication is not always a foolproof process although many proteins look for DNA damage or mistakes, damaged areas can still replicate. This can lead to gene rearrangements and serious problems in the body.

Some mutations are caused by mistakes in DNA replication. DNA replication isn’t always 100% complete. Sometimes, an incorrect base is inserted into the new DNA strand. This incorrect base can become permanent.

Breaks in DNA are caused by DNA replication errors, particularly those in regions that are difficult to replicate, known as fragile sites.

Breaks in DNA can cause cancer, mainly because they increase the risk of chromosome fragments rearranging themselves and activating genes that cause uncontrolled cell division.

The event horizon of a black hole is where gravity is such that not even light can escape. This is also the point I understand that according to Einstein time dilation will be infinite for a far-away-observer.

The statement "once anything passes through the event horizon, from the perspective of that object, nothing would change" is true.

The horizon would be the line that appears to divide a celestial body's ground from its own sky when observed by an observer standing on or close to the body's surface.

An event would be the collection of results from an experiment.

Answer:

B

Explanation:

Desalination remains expensive, as it requires enormous amounts of energy. The correct answer is b) The process uses fuel that is expensive.

Saline water which is typically sea water, is artificially transformed into fresh water through a process called desalination. Reverse osmosis and distillation are the two most used desalination techniques. There are several approaches. Although each has benefits and drawbacks, they are all useful.

The issue is that it takes a lot of energy to desalinate water. When salt is dissolved in water, it forms strong chemical bonds that are challenging to break. Desalinating water may be rather expensive since both the energy and the technology required are costly.

Desalination turns seawater into freshwater by removing the salt, however, it also has certain unfavorable effects on the ecosystem. Desalination facilities release trash and poisonous chemicals that are bad for the environment and animals. The procedure can also increase the salinity of saltwater, which has an impact on fish.

Therefore, the correct answer is b).
