Explain why the accidental and intentional introduction of new pests is likely to be an ongoing problem for future agriculture, and include possible approaches to solving the problem.

Answers

The introduction of pests in a new geographic region may have devastating consequences on crop yields. Invasive pest species often don't have natural predators or exhibit higher adaptive fitness.

Invasive species represent an important subject of concern in agriculture because they have the potential to drastically reduce crop yields.

Generally, invasive pest species don't have natural predators or exhibit higher adaptive fitness compared to well-established natural pest species.

In consequence, these species (invasive species) may cause considerable harm to crops.

Based on the chart, describe the trends that can be observed in animal and plant fossils as they evolved over time. Use evidence from the chart to support your conclusions.

Answers

Based on the chart, we can conclude that the first vertebrates were fish. Moreover, the chart also shows that flowering plants are the last plant taxonomic group that emerged on Earth.

In this case, the chart suggests that the earliest vertebrates (fish) evolved during the Ordovician period.

The main animal groups that emerged during vertebrate evolution include (in this order) amphibians, reptiles, mammals, birds and finally humans.

Moreover, according to the chart, the latest major group of plants to evolve were flowering plants during the Cretaceous period.

1. There are two birds that live in the same type of tree, same climate, and eat the same type of fruit. However, one is nocturnal (awake at night) and the other is diurnal (awake in the day). Explain why these two birds are considered to have different niches.​

Answers

Answer: different species

Explanation: They live in the same community like a Gouldian finch and a Double-Barred finch but are different species

However, one is nocturnal (awake at night) and the other is diurnal (awake in the day) as it consist of different species and they live in the same community like a Gouldian finch and a Double-Barred finch but are different species.

What shows the low light in the evening?

The hours of low light in the evening shows that it would be when humans would be most at risk from dangers. Species might make sense to seek shelter during this period.

As a result of their divergent evolutionary paths, various species have evolved in various ways to adapt to their habitats. The reason a certain species is nocturnal or diurnal has a variety of different potential causes. Perhaps at night, when light levels are low, when humans would be most exposed to dangers. The decision to seek sanctuary during this time may therefore be justified. Considering the various predatory dangers that mice and rats encounter, it is possible that being active at night reduces the threat posed by predators like birds who utilize their visual senses to identify prey.

Therefore, However, one is nocturnal (awake at night) and the other is diurnal (awake in the day) as it consist of different species and they live in the same community like a Gouldian finch and a Double-Barred finch but are different species.

A researcher sequences the genome of a variety of bacterial and eukaryotic cells. She finds that the bacterial genome is smaller, but that there are more genes for a given number of base pairs in the eukaryotic cells. In other words, there are fewer genes per unit of length of DNA in the eukaryotic cells. What do you predict she will find if she examines the DNA more closely

Answers

From this observation, it is possible to conclude that there are more repetitive sequences in the eukaryotic DNA than in the bacterial DNA. Prokaryotic genes do not contain introns.

Introns are internal non-coding segments of eukaryotic genes that must be removed to produce the final mature mRNA.

In prokaryotic genomes, there are no introns, and genes are expressed in groups known as operons.

Eukaryotic genomes contain highly repetitive intergenic (regulatory) and intragenic (introns) non-coding regions.

The trait must have no other advantage in fitness

The trait must be for the good of the species

The trait must be heritable

The trait must advance the goal of evolution

Answers

Answer:

For natural selection to occur, it is true that there must be genetic variation in the population.

Explanation:

According to evolution, natural selection implies the changes that occur in the genotype of a species, due to the effect of environmental factors, and which guarantee its survival through adaptive evolution.

For natural selection to occur, three fundamental conditions must exist:

A trait that can be inherited from one generation to another.

The trait is subject to variability between subjects of the same species.

Genetic variability can determine the possibility of reproductive success and survival.

Therefore, a necessary factor for natural selection to occur is that genetic variability exists in the population.

For natural selection to occur :-

There must be variation in traits in the population.The trait must cause the individual to evolve.The trait must be for the good of the species.The trait must be heritable.The trait must advance the goal of evolution.

Draw a punnett square to determine the possible types of noses their children could have had. (Use the genotypes from #2) a. List the possible genotypes and phenotypes for their children. b. What are the chances of a child with a long nose? out of or % c. What are the chances of a child with a stubby nose? out of st or__% d. Would their children be considered purebred like Dobby? Explain:​

Answers

Assuming a single diallelic gene coding for the trait and expressing complete dominance, the phenotypes, genotypes, and probabilities of getting each of them vary according to the parentals' genotypes. See the options below.

---------------------------------

Since I do not have the genotypes from #2, I will provide different potential scenarios for this question.

I advise you to check on them and see which one matches the genotype from #2.

Let us assume a single diallelic gene is coding for the trait and expresses complete dominance.

SCENARIO 1  ⇒ long nose is the dominant trait

Let us say that

L is the dominant allele and codes for long nosel is the recessive allele and codes for stubby nose

Since long nose is dominant over stubby nose

LL and Ll ⇒ long nosell ⇒ stubby nose

If Dobby comes from a purebred family and has long nose, his genotype must be LL.

And if Viola has stubbi nose, her genotype must be ll.

Cross 1

Parentals)    LL   x    ll

Gametes)  L    L     l    l

Punnett square)    L       L

                      l      Ll      Ll

                      l      Ll      Ll

F1) Genotype ⇒ 100% heter0zyg0us Ll

     Phenotype ⇒ 100% long-nosed

There is 100% chances for a child to have a long noseThere is 0% chances for a child to have a stubby noseThese children are not purebred

                                             **********

SCENARIO 2  ⇒ Stubby nose is the dominant trait

Let us say that

S is the dominant allele and codes for stubby noses is the recessive allele and codes for long nose

Since stubby nose is dominant over long nose

SS and Ss ⇒ stubby nosess ⇒ long nose

If Dobby comes from a purebred family and has long nose, his genotype must be ss.

And if Viola has stubbi nose, her genotype must be either SS or Ss.

There are two possible crosses.

Cross 1 : Violet is h0m0zyg0us dominant SS

Parentals)    SS   x    ss

Gametes)  S    S     s    s

Punnett square)   S       S

                      s     Ss     Ss

                      s     Ss     Ss

F1) Genotype ⇒ 100% heter0zyg0us Ss

     Phenotype ⇒ 100% stubby-nosed

There is 100% chances for a child to have a stubby noseThere is 0% chances for a child to have a long noseThese children are not purebred

Cross 2: Violet is heter0zyg0us, Ss

Parentals)    Ss   x    ss

Definition Of polar molecules and nonpolar molecules please?​

Answers

Answer:

Non polar molecules are symmetric with no unshared electrons. Polar molecules are asymmetric, either containing lone pairs of electrons on a central atom or having atoms with different electronegativities bonded.

Explanation:

When things are different at each end, we call them polar. Some molecules have positive and negative ends too, and when they do, we call them polar. If they don't, we call them non-polar. Things that are polar can attract and repel each other (opposite charges attract, alike charges repel).

Polar molecules occur when there is an electronegativity difference between the bonded atoms. Nonpolar molecules occur when electrons are shared equal between atoms of a diatomic molecule or when polar bonds in a larger molecule cancel each other out.
