Answers

Answer 1

Answer:

C. The Archaea have no nucleus.

Explanation:

Archaea have no organelles while Eukaryas do, in other words Archaea have DNA that is not in a nucleus.

Answer 2

The organisms in the domain archaea different from those in the domain eukarya is Archaea have no nucleus.

What are the characteristics of Archaea?

Archaea is a space of single-celled living beings. Prokaryotes are these microorganisms because they do not have cell nuclei. Initially referred to as archaebacteria, archaea were categorized as bacteria.

By interacting with both bacteria and their hosts, Archaea contribute to the ecosystem's and vegetation's functioning in the harsh bog ecosystem by carrying out functions related to nutrient cycling, stress response, and phytohormone biosynthesis.

The following characteristics of Archaebacteria have been identified as common: the presence of ribosomal and tRNA characteristics; 2) the absence of peptidoglycan cell walls, which are frequently replaced by a coat that is mostly proteinaceous.

What energy yield (in molecules of ATPATP per molecule of monosaccharide) would you predict for the bacterial catabolism of raffinose, a trisaccharide

Answers

Answer:

The correct answer is 2.67 ATP per molecule.

Explanation:

With the help of sucrose, it comes to known that the dissociation of a sugar-sugar bond generates one phosphorylated monosaccharide. Therefore, raffinose, which is a trisaccharide exhibits bonds of two sugar-sugar molecules. Post dissociation, they will generate one regular monosaccharide and two phosphorylated monosaccharides.  

There will be the generation of net ATPs by each phosphorylated monosaccharide as they are already phosphorylated. While the regular monosaccharide, which is first needed to get phosphorylated will only produce two ATPs. Thus, a total of 8 ATPs will be produced by one molecule of raffinose. After dividing by three monosaccharides, the molecule will produce 8/3 = 2.67 ATPs per monosaccharide.  

Describe at least 2 benefits and 2 drawbacks there might be for animal cells (including humans) to make their own food through photosynthesis.

Answers

Answer:

here.

Explanation:

Benefits would be that we'd be autotrophs, meaning that we'd be independent of an external source of organic compounds for energy. All we'd need is the sun and carbon dioxide. It's a simpler and less energy-consuming process than having to undergo digestion, absorption and then assimilation.

Cons would include the fact that it provides a very limited amount of energy only for the day. Which means humans will be inactive at the night time because the energy won't be able to support our activities. Since we don't have a surface area as big as leaves, our deep cells (like those of our organs and bones) will suffer most from the lack of energy since sunlight cannot penetrate our fat, muscles and bones. This can cause organ failure if our cells solely depended on diffusion.

Our high metabolic rate and our need for energy makes photosynthesis very very ineffective.

¿Qué características crees que deben tener los métodos anticonceptivos para ser eficaces en el control de la natalidad?

Answers

Answer:

Los métodos anticonceptivos para ser eficaces en el control de la natalidad deben ser seguros para las personas que los utilizan, es decir, no tener efectos adversos, o al menos, la menor cantidad posible. Ser reversibles, es decir, que no generen infertilidad de por vida. Deben ser además fáciles de usar, cómodos y fáciles de conseguir, esto es, económicos. Además deben ser eficientes en su objetivo de evitar la concepción, que es para lo que fueron creados.

a) There are three nucleotide in each codon, and each of these nucleotides can have one of four different bases. How many possible unique codons are there?
b) If DNA had only two types of bases instead of four, how long would codons need to be to specify all 20 amino acids?

Answers

Answer:

Explanation:

There are 64 possible codons to be specified for, If we have three nucleotides with 4 bases the set of all combinations can encode

4x4x4 = 64 amino acids

This will give 64 different combinations of four nucleotides

If we have 2 bases with 4 nucleotide we have a possibility of having 16 codons specifying for 20 amino acid.

If we have 2 nucleotides with 4 bases the set of combination is

4×4 = 16 amino acids of four nucleotides

The authors constructed a phylogenetic tree using nucleotide substitutions as well as a tree built using indel information. What relationships did each support; do they agree completely with each other

Answers

Answer:

Both types of genetic data can be used to generate evolutionary trees, but indels increase phylogenetic resolution

Explanation:

Nucleotide substitutions, also known as single nucleotide polymorphisms (SNPs), are genetic changes at specific positions in the genome that can be used to compare two or more sequences through a local alignment. SNPs enable to estimate the evolutionary distances among sequences and they are the most common type of genetic variation used to draw phylogenetic trees. On the there hand, sequence insertions and deletions, collectively referred to as indels, can increase the resolution of an evolutionary tree because this type of variation is less frequent in the population (i..e., indels generally have higher deleterious effects than SNPs). However, it is important to note that, in the case of indels, it is imperative to include more complex alignment algorithms in order to analyze data derived from this type of genetic variation.

DIHYBRID CROSSES
In all of the examples we have only been concerned with one trait. It is possible, however, to track the inheritance of more than one trait at a time. When one is investigating the inheritance of two traits at once the cross is called a dihybrid cross. Strictly speaking, a dihybrid cross is one between two individuals that are heterozygous for two traits, meaning that they are hybrids in two senses. For example, in humans eye color is determined by multiple factors, but if we compare only blue eyes to brown eyes, brown is dominant (R) and blue acts as a recessive allele (r). If a man heterozygous for both eye color and bent little finger has a child with a woman who also heterozygous for both traits, this would be a dihybrid cross. Which is/are possible genotypes for a person with bent little finger and blue eyes?
1. bbrr
2. BBRR
3. BBrr
4. Bbrr
Referring to the previous question, which is/are possible genotypes for a person with straight little finger and blue eyes?
1. bbrr
2. BbRr
3. Bbrr
4. bbRr

Answers

Answer:

Question 1: bbrr

Question 2: bbRr

Explanation:

To address the first question, the possible genotype for someone with bent little finger and blue eyes would be bbrr.

Since brown eye (B) is dominant over blue eyes (b), in order for the blue eye color to be expressed, it has to be in bb condition. The only option with bb genotype is option 1.  

For the second question, the possible genotype for a person with a straight little finger and blue eyes would be bbRr.

Blue eye genotype is bb as explained in the first question while straight little finger would be Rr since the bent little finger has been represented by the genotype rr in the first question.

Vitamin K, a fat soluble vitamin is rich in green leafy  vegetables,and also produced by bacterial in the intestine.

Its major function is blood clotting or arrest of bleeding to prevent blood loss.

Antibiotics especially with Cephalosporins,reduces Vit. K absorption in the intestine. Intake of these antibiotic kill the targeted bacterial together with the the bacteria which produces Vit. K in the intestine.

Hence when antibiotic is taken  with low level of Vit, K the individual is prone to excessive bleeding or haemorrhage,because the concentration of the vitamins is further depleted.

In which of the following ways is DNA replication different from DNA transcription?

Answers

Answer:

Thymine is used in replication while uracil is used in transcription.

Explanation:

New cells can only be created after transcription has taken place. Replication results in mRNA strands while transcription creates new DNA. Transcription happens outside the nucleus and replication happens inside the nucleus. Thymine is used in replication while uracil is used in transcription.

DNA replication is a process whereby DNA makes a copy of itself while DNA transcription is a process whereby a messenger RNA is synthesized from a DNA strand.

Both processes involve the building-up of nucleotides or purine.pyrimidine bases. Replication involves building up of cytosine, guanines, adenine, and thymine bases while in transcription, the thymine base is replaced by uracil base.

Hence, the correct answer is that Thymine is used in replication while uracil is used in transcription.

You will be the expert: Imagine you are teaching a class on controlling microbial growth in the environment. To test your students, you will present them with a scenario including a site and some probably microbes present. They must design a strategy to eliminate harmful microbes from the area.
1A. Come up with a scenario/situation including a site and some probable microbes present.
1B. Come up with possible solution/analysis to that scenario/situation in order to eleminate harmful microbes.

Answers

Answer:

A possible scenario would be many rusty pipes with abundant soil in an abandoned area or house.

The probable microorganism would be clostritium tetani, which causes tetanus disease.

This clostridium is eliminated once the oxidized surfaces are exterilized, eliminated and cleaned with disinfectants.

In addition, it could be sprayed with disinfectant on the ground to kill the presence of possible spores of this bacterium.

Explanation:

Clostridium tetani is a bacterium that affects the central and peripheral nervous systems of humans.

Today there is a vaccine for this bacterium, which is called tetanus and is administered against a possible accident, surgical act or risk of having been inoculated with the bacteria.

The current tetanus vaccine has a longevity of 10 years in the human organism, once this period has passed, the booster should be given.

This bacterium coexists with other microorganisms in this environment with accumulations of soil and rust, which the most dangerous would be fungi (they trigger deep mycosis). An example of these fungi is: histoplasma capsulatum, responsible for generating histoplasmosis.

The scenario or situation including a site and some probable microbes present would be a controlled Laboratory.

The possible solution or analysis to that scenario in order to eliminate harmful microbes is fumigation.

Identification of microbes is critical in determining which microbial removal strategies will be used in a site.

The scenario or situation including a site and some probable microbes present would be a controlled Laboratory where microbes are isolated from the site via cultured methods. When carrying out microbial culture, the culture plates usually support the growth of a wide range of microorganisms. As a result, biochemical approaches may be used to distinguish one microbial population species from another. They may exist in various species of fungi, viruses, bacteria, protozoa, etc.

The elimination of microbes is dependant on the size of the area being analyzed. This is done by the application of formaldehyde to the area. Other methods include alcohol sterilization and heat sterilization for cleaning and sanitizing surfaces of the laboratory and equipment respectively.
