What effects would you expect uncontrolled celiac disease to have on children? How do these effects relate to what is shown in the model?
Answer:
Explanation:
Because the villi get damaged, they can’t absorb enough nutrients. So, children might have slow or stalled growth and development because they don’t get enough nutrients.

after staining what should be the color of vegetative cells
Answer:
See below
Explanation:
As a result of staining the cells, while all of the cells now appear pink, the vegetative cells show some area that has not been stained pink (perhaps because they did not take up the dye). This is a clear indication that they are in their vegetative state as opposed to the normal cell growth stage as demonstrated by the remainder of the cells.
The genomic DNA of an organism has a base composition of 40% C-G base pairs and 60% A-T base pairs. Assuming a random sequence of bases, what is the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3'?
Answer:
The correct answer is (0.2)^4.
Explanation:
Based on the given information, the given genomic DNA is A-T rich, and the base pair composition is C-G = 40 % and A-T = 60%. Therefore, as per Chargaff's rule, Each C and G will possess 20%, and each A and T will possess 30%.
Therefore, the probability of each base will be,
C = 20/100 = 0.2
G = 20/100 = 0.2
A = 30/100 = 0.3
T = 30/100 = 0.3
Now the expected frequency of the Tsp E1 restriction sites 5'-CCGG-3' will be 0.2 * 0.2 * 0.2 * 0.2 = (0.2)^4.

Weight loss is a common goal among many aduls, and losing woight can be very difficult. There are countiess approaches to consider, but an often-overlooked area is the role of an individuals evironment. Environmental factors can be a good place to start for people looking to Iose weight or prevent weight gain. Which of these statements describe environmental factors that can make it difficult for an individual to loose weight or maintain weight loss?
to lose weight or meintain weight loss?
a. decreased portions sizes in restaurarts and movie theaters.
b. increased use of personal vehicles, telephones, and computers.
c. increased number of meals eaten outside the home
Answer:
c. increased number of meals eaten outside the home
Explanation:
Environment is the surrounding of living organism, where he gets to survive by meeting its needs.
Environmental factors are factors in the environment that are associated to growth and development example is temperature.
The environment an individual stays have a great influence on the physical expression and character of the individual.
For a fat person the environment had played out his role which should be controlled to achieve a significant weight loss. Increasing number of meals eaten outside the house is one major factor that would not allow such individual to loose weight. Intake of food should be greatly controlled and watched to achieve weight loss.
a) List three examples of ruminant livestock. b) Describe how ruminant cattle digest food? c) Why do cattle produce more methane than other types of animals?
Answer:
a)Ruminants include cattle, sheep, goats, buffalo, deer, elk, giraffes and camels. These animals all have a digestive system that is uniquely different from our own. Instead of one compartment to the stomach they have four. Of the four compartments the rumen is the largest section and the main digestive centre.
b)Digestion in ruminants occurs sequentially in a four-chambered stomach. ... The mass is finally passed to the true stomach, the Abomassum, where the digestive enzyme lysozyme breaks down the bacteria so as to release nutrients.
c)The difficult-to-digest grass ferments in the cows' stomachs, where it interacts with microbes and produces gas. Thus,cattle produce more methane than other types of animals.

) Recall what you know about crossing over, independent assortment, and random joining of sex cells during sexual reproduction.
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.
The nerve cells in your body must constantly remove substances from the cell against the concentration gradient. What type of process most likely takes place to remove substances from a cell against the concentration gradient? Explain.
Answer and explanation:
Active transport refers to a procedure, which withdraws substances from a cell against the concentration gradient. During the process, the molecules move from low concentration to a high concentration.
The mechanisms of active transport need the application of the energy of the cell, generally in the form of ATP. If a substance needs to move within the cell against its concentration gradient, that is, if the substance's concentration within the cell is more than its concentration in the extracellular fluid, then the cell must utilize energy to move the substance.

In his deletion mapping experiments, Benzer coinfected bacteria with one phage that contained a point mutation and one phage that contained a deletion mutation. Assume that the point mutation and deletion mutation are not in overlapping regions of the phage genome. What phage recombinants would you expect if a crossing-over event occurred between the regions of the two mutations?
Answer:
The correct answer would be - there will be wild type and double mutant (contains both the deletion mutation and the point mutation)
Explanation:
It is mention that the deletion mutation and point mutation are non-overlapping or no overlapping regions in the phage genome. A crossing-over event between the regions of these two mutations would get wild-type which means there would be neither point mutation nor deletion mutation and other would be a double mutant that contains both mutation - the point mutation and the deletion mutation.
Thus, the correct answer is - there will be wild type and double mutant (contains both the deletion mutation and the point mutation)

1. Explain why some heterotrophs can be described as both a primary consumer and a secondary consumer. What are these heterotrophs called
Answer:
Heterotrophic species that eat organisms from different trophic levels
Explanation:
Humans are examples of primary and secondary consumers because we are able to eat different types of living forms, thereby acting in the food chain as primary consumers (eating plants) in certain conditions and as secondary consumers (eating animals) in different conditions. Many heterotrophic organisms act at different levels by feeding primary producers and primary consumers based on specific trophic strategies. In consequence, the classification between primary and secondary consumers is arbitrary since it varies according to the trophic strategy adopted by the organism.

Polysaccharides are polymers of monosaccharides. Homopolysaccarides are made up of only one type of monomer, whereas heteropolysaccharides are composed of at least two different kinds of monomers.
Are starch, glycogen, cellulose, and chitin classified as homopolymers or heteropolymers?
A. All four polysaccharides are homopolymers.
B. All four polysaccharides are heteropolymers.
C. Starch is a heteropolymer, whereas chitin, cellulose, and glycogen are homopolymers.
D. Chitin is a heteropolymer, whereas starch, cellulose, and glycogen are homopolymers.
Answer:
Option A
Explanation:
All four types of polysaccharides are homopolymers ie they are made up of repeating units of only one type of monomers.
Starch, glycogen and cellulose are made up of repeating monomeric units of glucose with the number of glucose units and the different linkage types different these molecules. E.g the linkage between glucose units in glycogen is alpha 1-4 linkages and in cellulose, we have glucose in beta 1-4 linkages.
In chitin, a derivative of glucose is present in repeating units, here, we have N-acetyl-D-glucosamine in beta 1-4 linkages.

In Lake Victoria (the largest freshwater lake in Africa), researchers recently found that in one cichlid species, male fishes with brighter red coloration maintain large territories. Red males are at an advantage because female cichlids tend to choose males with brighter color and larger territory size. Assuming that red coloration is heritable, what do you expect would occur if some females of this species began to prefer male cichlids with blue coloration?
Answer:
The population of cichlids with blue coloration increases.
Explanation:
If the female prefers blue colored cichlids, so they mate with each other and increase occurs in the population of blue colored cichlids and with the passage of time bright colored cichlids decrease in number due to less reproduction with female cichlids. So those cichlids becomes dominant in the lake to which more female mate and those which receive less female are less in number and having lower territory size.
Cichlid is the fish variety found diversely in South America and Africa. They are primarily herbivores and feed on plants and algae. Cichlids mate both with single or multiple partners.
Speciation would occur if some females of this variety began to prefer male cichlids with a blue coloration. The population of blue colored fishes will increase.
The explanation for the answer is:
Female mate choice plays a major role in speciation. They play important role in differentiation and speciation.After several generations of mating with the blue parent, all the offspring will become blue.Change in the recurrence of variation or the genetic drift where red-coloured fishes are preferred will result in the fixation.This female choice would act as a barrier to the gene flow.The mutation rate in genes coding for the colour will increase.
