Answers

Answer 1

Answer:

Coevolution

Explanation:  

Coevolution refers to the mechanism where two or more species interact by the evolutionary process of natural selection. The mechanism of coevolution was mentioned by Darwin to explain the existing interactions among flowering plants and insects, in a similar manner to the example above described. Examples of coevolution also include the race between pathogenic organisms and the immune responses or the emergence of resistance in pathogens that affect genetically modified (originally resistant) crop varieties.

Answers

Answer:

There are several changes that occur on the earth's surface but also affects the changes below the surface, some of them are as follows:

When rainfall occur on the sandy surface on earth, it looses the soil under the surface and can cause landslides.Imbalance in the food chain above or on the earth surface can affect the nutrient quantity below the surface that is essential for soil bacteria and other microorganisms.Deforestation can also loosen the soil and soil under surface can shift its position.Use of chemicals on agriculture surface can lead to change the fertility of soil below the surface.

In pea plants, purple flower color, C, is dominant to white flower color, c. The table shows the frequencies of the dominant and recessive alleles in three generations of peas in a garden. Allele Frequency for Flower Color in Peas Generation p q 1 0.60 0.40 2 0.64 0.36 3 0.75 0.25 4 0.80 0.20 Which generation showed the greatest frequency of having one of each allele? generation 1 generation 2 generation 3 generation 4

Answers

Answer:

generation 1

Explanation:

The allele frequency is a term that represents the frequency that an allele can appear in a given population. This term can help to develop conclusions about the genetic diversity that a region presents in relation to the individuals that compose it.

In relation to the question above, generation 1 had the highest frequency of having one of each allele. This is because this generation presents the maximum frequency of the dominant and recessive alleles in a coherent way, 0.60 and 0.40. However, the other generations showed a steady and progressive decrease in the recessive allele.

In jimsonweed, purple flower (P) is dominant to white (p), and spiny pods (S) are dominant to smooth (s).
A true-breeding plant with white flowers and spiny pods is crossed to a true-breeding plant with purple flowers and smooth pods. Determine the phenotype of:__________.
a) the F1 generation;
b) the F2 generation;
c) the progeny of a cross of the F1 plants back to the white, spiny parent; and
d) the progeny of a cross of the F1 back to the purple, smooth parent.

Answers

Answer:

See attached image for detailed punnet squares and diagrams

a) F1 generation: Purple flower and spiny pods (PpSs) offsprings

b) F2 generation: Puple flower, spiny pods (9), Purple flower, smooth pods (3), White flower, spiny pods (3), white flower, smooth pods (1).

c) The progenies are: PpSS (4), PpSs (4), ppSS (4), and ppSs (4)

d) The progenies are: PPSs (4), PPss (4), PpSs (4), Ppss (4)

Explanation:

This question involves two distinct genes in jimsonweed; one coding for flower colour and the other for pod texture. The alleles for purple colour (P) and spiny pods (S) are dominant over the alleles of white flower (p) and smooth pods (s) in the two genes respectively.

A true-breeding plant with white flowers and spiny pods will have genotype: ppSS while a true-breeding plant with purple flowers and smooth pods will have genotype: PPss. In a cross between these two parents, the following combinations of gametes will be produced:

ppSS- pS, pS, pS and pS

PPss- Ps, Ps, Ps, PS

a) Hence, the F1 offsprings from this cross will possess a heterozygous genotype: PpSs, which is phenotypically purple-flowered and spiny-pod.

b) if the F1 offsprings are self-crossed i.e. PpSs × PpSs, gametes PS, Ps, pS, ps will be produced by each parent. These gametes will be used in a punnet square (see attached image) to produce the following F2 offsprings in proportion:

Purple flower, spinny pods (9)

Purple flower, smooth pods (3)

White flower, spiny pods (3)

White flower, smooth pods (1)

c) if the F1 offsprings are crossed back with the white, spiny parent i.e. PpSs × ppSS. The following progeny of offsprings will be produced: (see attached image)

PpSS (4),

PpSs (4),

ppSS (4), and

ppSs (4)

d) if the F1 offsprings are crossed back with the purple, smooth parent i.e. PpSs × PPss, the following progeny will be produced:

PPSs (4),

PPss (4),

PpSs (4), and

Ppss (4)

The true breeding plant.

As per the question, the jimson weed is a purple flower with capital P and is dominant to white (p) and a spiny pods of (S) which are dominant to smooth (s). The Punnett square method is used for the method. The true breeding have seperate types of genetic make ups.

Answer is F1 generation (PpSs), F2 generation has 9 purple flowers.

True-breeder plant with the white flowers and spiny pods s crossed to a true-breeding plant with the F1 gene will be a flower and spiny pods (Pp Ss) offspring. For the F2 gene Purple flower, spiny pods (9), Purple flower, smooth pods (3), White flower, and spiny pods (3), the white flower, and a smooth pods (1).The progenies are of  PpSS (4), PpSs (4), pp SS (4), and ppSs. The progenies follow PPSs (4), the PP ss (4), PpSs (4), Ppss.

Answers

You didn't put the answer options, but the frog life cycle phases are:

Mating: In this phase two adult frogs, a male and a female, mate in the water or on plates. At this point, the male frog wraps his arms around the female and overlaps over her back. Spawning: At this point, the female releases the eggs into the water, ready to be fertilized by the males. Fertilization occurs outside the female's body. Eggs: Some fertilized eggs will be devoured by small animals, but those that survive will hatch 7-9 days after fertilization, releasing a frog shape, called a tadpole.Tadpole: It is similar to a fish and is formed by tail, mouth and gills. After 7 days of life, you will be able to swim and feed on algae. Four weeks later he will develop teeth and skin. When he reaches 9 weeks he will begin to change his shape, growing in size and developing head and legs. At that moment it will look more like a frog, but it still has a long tail. Metamorphosis of the fish: Up to twelve weeks of age it will reach the shape of a frog and start to feed on insects. Gradually it will lose its tail and its tongue will grow. The 16 weeks will become an adult frog, being able to mate and restart the cycle.

Explanation:

Animals should be matured to reproduce.

The animals can reproduce sexually, that involves fusion of sperm and ova inside the body.

Autosomal dominant and recessive: Autosomal dominant states a pattern of inheritance in which an individual carries one normal gene and one copy of a mutant gene while autosomal recessive states a pattern of inheritance in which an individual have two copies of the mutant gene.

Incomplete dominance:  Incomplete dominance states a heterozygous condition in which both the alleles present are partially expressed and produces intermediate phenotype.

Codominance: In codominance and individuals receive alleles, if both the alleles are different including dominant and recessive, dominant allele will be expressed while recessive will be masked.

Multiple alleles: organisms with multiple alleles exist with two copies of every gene present in a population with variation in genes.

Sex linked gene: In humans and some other organisms, sex linked genes are influenced by genes on the X chromosome. for example: If a gene is present on the X chromosome only and not the Y chromosome.

A certain strain of E. coli is constitutive for the enzymes for lactose metabolism. On an F' plasmid you have the choice of adding one (but only one) element of the lac system to make the bacteria a merodiploid for that element. Assume the original E. coli has wild-type structural loci. If your goal is to determine whether the lac operon is constitutive because of a mutant regulator OR because of a mutant operator, which one wild-type element of the lac operon would you add using sexduction?
a. operator region
b. regulator (repressor)
c. gene promoter region
d. structural genes

Answers

Answer:

The correct option is B: regulator (repressor)

Explanation:

A regulator gene would be required to control the expression by either increasing or decreasing the transcription of that particular gene. In doing so, the amount of protein product made by the gene can be regulated. In the wild-type case, the gene lacl is responsible for generating the mRNA which translates to a Lac repressor protein that binds at the operator region.
