Why do stems have bark? What does the phloem do?

Answers

Answer:In old stems the epidermal layer, cortex, and primary phloem become separated from the inner tissues by thicker formations of cork. Due to the thickening cork layer these cells die because they do not receive water and nutrients. This dead layer is the rough corky bark that forms around tree trunks and other stems.

Binding of the lac repressor protein to the lac operator is regulated allosterically. This means that the presence of a specific small molecule that binds to the lac repressor controls whether the repressor can bind to the lac operator, and therefore whether the operon is turned on or off. Can you sort the following conditions based on whether they are associated with the lac operon being turned ON or turned OFF?

a. Allolactose is absent
b. Allolactose is present
c. RNA polymerase cannot transcribe the operan genes
d. The lac repressor protein cannot bind to the lac operator

Answers

Answer:

a. OFF

b. ON

c. OFF

d. ON

Explanation:

Allosteric regulation is a process by which a particular molecule activates or inhibits an enzyme, by binding to a site different from the active site of the enzyme. Allolactose is a disaccharide that binds to the allosteric site of the lac repressor protein, triggering a conformational change in the protein that prevents the binding of this repressor to DNA. Moreover, RNA polymerase (RNA pol) is an enzyme required for the process of transcription, and therefore when this enzyme cannot bind to operon genes the lac operon is being turned OFF.  Finally, the lac operator is a nucleotide sequence where RNA pol binds, and the lac repressor binds to the lac operator in order to block the transcription of the lac operon.

What is the role of a ribosome in protein production?

A. It is the site where amino acids join to tRNA molecules.
B. It is the site where mRNA codons and tRNA anticodons meet.
C. It is the site where a protein strand is folded into its correct shape.
D. It is the site where proteins are packaged and sent where they are needed.

Answers

Answer:

Ribosomes are the sites in a cell in which protein synthesis takes place. ... Within the ribosome, the rRNA molecules direct the catalytic steps of protein synthesis — the stitching together of amino acids to make a protein molecule. In fact, rRNA is sometimes called a ribozyme or catalytic RNA to reflect this function.

what is the difference between a disease and an infection​

Answers

Answer:

disease occur when the cells in your body are damaged and multiplies and infection occurs when bacteria is there.

hopefully this helps.

A disease is any condition in which the body is not working properly. Many diseases are quite trivial and clear up quickly without treatment, for example a cold. Some are severe, even life-threatening, such as many, not all, types of cancer.

Infections are one particular type of disease. An infection is a disease caused by a living organism (a germ), which is living in the body of the affected person. The germ may be a bacterium, virus, fungus or parasite.

Like all diseases, infections vary in how severe they and whether they need treatment. The common cold is a virus infection; colds are not dangerous unless a person is already sick or very weak. Tuberculosis is a bacterial infection, which can be very difficult to treat and causes many deaths every year.

All camels are basically similar in structure. They have developed adaptations for coping with both heat and dehydration.
Which of the following does not benefit the camel as a means of preventing dehydration?

a.Camels can extract water from their solid wastes.
b.Camels' ears are lined with fur to keep out sand and other blowing matter.
c.Their kidneys are capable of concentrating urine to reduce water loss
d.Camels are able to locate water in any environment.

Answers

Answer: b

Explanation:

Camels ears are lined with fur to keep out sand and other blowing matter

The Cambridge family includes the unusually shaped Arabian camel (Camelus dromedarius), also referred to as the one-humped camel. This animal is perfectly suited to the harsh desert climate and high levels of heat stress. Thus, option B is correct.

What camels are adaptations for heat and dehydration?

Camels have evolved to survive in extremely hot and cold climates.In contrast to many other mammals, camels store the majority of their body fat in their humps, which allows for better thermoregulation. It makes it easier for them to release heat from their body in hotter climates. Camels rarely perspire.

Camels are ideally suited for desert survival. They have developed wide, flat feet to disperse their weight across the sand, among other adaptations. Thin fur everywhere to allow for rapid heat loss, and dense fur on the top of the body for shading.

Therefore, The kidney may be able to retain water if the generation of cholesterol is reduced. Camels produce pee that is highly concentrated, retaining the maximum amount of water.

As part of a forensic analysis, you have been asked to determine an individual's ancestry using skeletal indicators. The metric measurements you collect indicate that the individual is of European ancestry, but you see several nonmetric traits in the cranium that are typically found in individuals of Asian ancestry. Why might the two methods give different results

Answers

Answer:

Due to difference in the methods that is used for analysis.

Explanation:

The two methods give different results because we used two different types of measurements i. e. metric measurement and nonmetric traits. In the metric measurement, we calculate the quantitative character of an individual that gives information about the current status of an individual, while on the other hand, in non-metric traits refers to the method which is used to evaluate genetic connections within and between populations that were present in the past.

Two Drosophila with genotypes AABBCC and aabbcc are crossed to produce a heterozygous offspring, AaBbCc (the gene order is unknown). This AaBbCc Drosophila is crossed with an aabbcc Drosophila, resulting in the offspring below: Number: Phenotype: 600 ABC and abc 200 AbC and aBc 150 ABc and abC 50 Abc and aBC a. Which phenotype represents the double crossovers

Answers

Answer:

The double recombinant individuals are less frequent ---> Abc and aBC

Explanation:

We can know if genes are linked, by looking at the progeny distribution. In a tri-hybrid cross, If individuals, whose genes assort independently, are test crossed, they produce a progeny with equal phenotypic frequencies 1:1:1:1:1:1:1:1. If we observe a different distribution, meaning that phenotypes appear in different proportions, we can assume that genes are linked in the heterozygote parent.

We can recognize the parental gametes because their phenotypes are the most frequent in the descendants, while the double recombinants are the less frequent. Finally, the simple recombinant gametes are the ones with intermediate phenotypes frequencies.  

In the present example, the phenotypic ratio shows different proportions than the expected ones if they were not linked.

We can recognize the parental gametes in the descendants because their phenotypes are the most frequent,

ABC and abc   600    

while the double recombinants are less frequent.

Abc and aBC  50  

And simple recombinant gametes produced by the cross, which frequencies are intermediate.  

AbC and aBc 200 ABc and abC 150
