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.

Answer:

Crossing over is the process of interchange of genetic information among non-sister chromatids of homologous chromosome pairs during meiosis (specifically during synapsis in prophase I). During this process, the synaptonemal complex enables the interchange of chromosome fragments between non-sister chromatids through crossing over. Moreover, in sexual reproduction, the zygote diploid cell can be generated by the random joining of fully differentiated haploid gametic cells (male and female gametes). The combination of random joining with the phenomenon of crossing over is known to considerably increase the genetic variation of the resulting offspring. After zygote formation, the successive cycles of cell divisions during embryonic development will develop an organism that during its adult stage will reproduce via sexual reproduction.

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.

Answer:

6NADH

Explanation:

In the kreb's cycle NAD is  reduced during the reduction of 6-carbon citrate to 5 carbon Alpha-Ketoglularate.

The second is produced during the conversion of 5carbon alpha ketoglutarate to succinate. Lastly in  the conversion of fumirate  to oxoloacetate;another NADH  is formed.

However, since two pyruvate enters the Kreb's cycle therefore 6NADH(three NADH per cycle of Citric)  are produced for each molecule of glucose that is broken down from glycolysis.

Remember,each glucose molecule goes through 2 cycles of Kreb.

Futhermore co-enzyme FADH2 are also produced,with 2 molecules per 1 glucose.

These Co-ezymes transfer hydrogen ions,into the matrix of the mitochondria,where is is splits to protons and  electrons.

The electrons formed the ETC,which produce PMF  for transporting protons into the intramembranes for electrochemical gradients needed to generate energy for ATP s synthesis,by ATP synthase.

Answer:

A food sample is dissolved in boiling water.

Explanation:

A small amount of Benedict's reagent is added and the solution begins to cool. In the next 10 minutes, the solution changes colour. if it turns blue, there is no glucose present in it.

As it is heated, it turns yellow. The hotter the colour of the reagent, the higher the concentration of reducing sugar. E.T.C.

There is more,e.t.c.

Answer:

i think that it's false.

Explanation:

Natural law is a theory in ethics and philosophy that says that human beings possess intrinsic values that govern our reasoning and behaviour. Natural law maintains that these rules of right and wrong are inherent in people and are not created by society or court judges.

The Interests Theory Approach. Advocates of the interests theory approach argue that the principal function of human rights is to protect and promote certain essential human interests. Securing human beings' essential interests is the principal ground upon which human rights may be morally justified.

Explanation:

Answer:

B. Heterotrophic

Explanation:

Heterotrphic animals depend on other orgamisms for food. They are made of carnaviors and omnavores. They eat other animals for food.

Answer:

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.

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.

Explanation:

the process by which the organism obtsin their their food is called feeding of living thing.

Answer:

Explanation:

Feeding is the process by which organisms, typically animals, obtain food. Terminology often uses either the suffixes -vore, -vory, -vorous from Latin vorare, meaning "to devour", or -phage, -phagy, -phagous from Greek φαγεῖν (phagein), meaning "to eat".

A phenotypic ratio is a quantitative relation between phenotypes showing the number of times the frequency of one phenotype correlates with another. When a researcher would like to obtain the gene expression for generations of an organism, they use the phenotypic ratio obtained from a test cross.

There are two dogs that are heterozygous for black coat color. In this breed, black fur is dominant over white fur. Thus, heterozygous dogs and homozygous dominant dogs have the same phenotype of black fur and homozygous recessive individuals have white fur.

Explanation:

Animals should be matured to reproduce.

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

Few animals can also reproduce asexually, asexual reproduction does not involve the fusion of gametes, the genetic material is combined to produce an offspring that has inherited the genes of the parent.

Answer:

to organize them and speak about them accurately

Explanation:

There are millions of species that exist on Earth. Many of them are yet to be discovered. They are named and classified into specific groups. This helps in organizing each specie according to the characteristics, and traits. The classification is done to show the hierarchy and focuses on the relationships that the organisms possess with other organisms about evolution. Classification helps in identifying and analyzing any specific specie accurately and particularly.

The ball and socket joint is the one that can perform all those movements.

Explanation:

Ball and socket joint, also know as spheroid joint are types of joints where the part of the bone that articulates with the other bone has a spheroidal shape or ball shape that fits in the depression of the other bone, which means that they are a synovial enarthrosis joint. It has a wide range of movements because it can move in the transverse, vertical, and sagittal axes. An example of this joint is the shoulder, between the scapula and the humerus.
