Answer: They both have genetic material
Explanation:
Place the steps of mycobacterium tuberculosis pathogenesis in order. I was just curious to know what the correct order was since this was a homework question from my Microbiology class.
Pathogenesis begins with the entry of the bacteria into the body through the nasal passages. (C)
In the alveoli, macrophages phagocytose the bacilli and destroy them. However, if bacterial multiplication continues and the bacillus inhibits the formation of the phagolysosome (D), the bacilli can lyse the macrophages.
Subsequently, the bacilli released during macrophage lysis are disseminated, provoking an inflammatory response (B). Here, if the immune response is mediated by monocytes, it can lead to encapsulation of the bacteria.
Eventually, these encapsulates may break down releasing more bacilli that will be expelled through coughing (A).
Therefore, the answers would be as follows:
C. M. tuberculosis is inhaled through airborne droplets
D. M. tuberculosis prevents phagocytosis through the actions of its mycolic acid and cell wall
B. M. tuberculosis continues growing inside the lungs and damages the tissue
A. M. tuberculosis bacili break out of its tubercule and is expelled through coughing

Explain the concept of half life
Answer:
Explanation:
Half-life is defined as the time it takes for one-half of a radioactive element to decay into a daughter isotope. As radioactive isotopes of elements decay, they lose their radioactivity and become a brand new element known as a daughter isotope.
How does the reactivity of the elements change as you go down the periodic table
Answer:
The farther to the left and down the periodic chart you go, the easier it is for electrons to be given or taken away, resulting in higher reactivity
Answer:
The metallic character increases as you go down a group. Since the ionization energy decreases going down a group, the increased ability for metals lower in a group to lose electrons makes them more reactive.

Show the reciprocal cross: A red-eyed female (homozygous) and a white-eyed male. How many offspring will have white eyes and what is their sex?
When we see the reciprocal cross between a red-eyed female (homozygous) and a white-eyed male,we observe that none of the offspring will have white eyes. Additionally, the sex of the offspring will be half male and half female since the ratio of males to females is 1:1.
The reciprocal cross for a red-eyed female (homozygous) and a white-eyed male can be shown as follows:Female (XrXr) x Male (XwY). Females have two X chromosomes and males have an X and a Y chromosome. Red eyes are dominant to white eyes; therefore, we use Xr to represent red eyes and Xw to represent white eyes.
The offspring are as follows:All F1 females are heterozygous (XrXw).All F1 males are hemizygous (XrY).The F1 generation will have red eyes since the dominant allele is present.
None of the F1 individuals will have white eyes as the recessive allele is not present in the F1 generation.

Why Did The Children In (III-A) And (III-E) Not Get The Disease When Both Fathers Had The Disease?
In the case of the children in (III-A) and (III-E) not getting the disease when both of their fathers had the disease, there are several potential explanations for why this could have occurred.
One possibility is that the children were exposed to the same form of the disease, but that the form of the disease they were exposed to was not as strong or as virulent as the form of the disease their fathers had. This could be due to differences in the strain of the disease, or even due to differences in the environment in which the children were exposed. In either case, the weaker form of the disease could be easier for the children’s bodies to fight off, making them less likely to contract it.
Another possibility is that the children had some form of immunity to the disease, either through natural immunity or through a vaccine. Natural immunity is when the body has been exposed to a similar virus or bacteria before, and as a result, has developed an immunity to it. Vaccines can also provide immunity to a particular disease, and the children may have been vaccinated before they were exposed to the virus or bacteria that their fathers had.

Explain the limitation binomial nominclature (15 marks)
Answer:
- Binomial nomenclature is a widely accepted naming system, which is used in the naming of living things. Multiple native names make it extraordinarily tough to establish an organism globally and maintain an observation of the variety of species. Thus, it creates quite a lot of confusion. To eliminate this confusion, a normal protocol came up. According to it, every organism would have one scientific title which might be utilized by everybody to establish an organism.
What is binomial nomenclature?
Binomial Nomenclature follows a universally accepted naming system, which is used to provide a scientific name to a known organism.
Binomial Nomenclature also known as the binary nomenclature.
It uses two-terms during the nomenclature of a specie (plants, animals, and living organisms) that is why it called two-term naming system.
The scientific name of an organism or binomial nomenclature consists of two words, such as the generic epithet and describes the genus and the specific epithet and refers to the species of the organism.
Both of this term is written in italic and the genus name is capitalized.
Binomial nomenclature was given by Swedish botanist and physician Carl Linnaeus. He also called the founder of modern taxonomy.
Carl Linnaeus described and classified thousands of species of plants and animals in his book Systema Naturae.In this technique, there are particular guidelines that are followed while naming organisms. This normal algorithm is relevant to plants and animals whereas giving them distinctive names inside a given system.There are two worldwide codes such as the International Code of Botanical Nomenclature (ICBN) deal with the biological nomenclature for plants and the International Code of Zoological Nomenclature (ICZN) deal with the biological nomenclature of animals.
These two codes agreed upon by all of the biologists over the world for the naming protocol. These codes ensure that every organism will get a selected identity and that identity is globally recognized.
Summary of the limitation binomial nominclature:
- Some of the main drawbacks of binomial nomenclature are: If two or more names are actually in use in compliance with the priority rule, the appropriate name will be used first and the other names will end up being synonyms because authenticity is synonymous with the senior.

From the start codon through the stop codon, the length of the
fully processed AURKA mRNA is 1,212 nucleotides. Calculate the number of amino
acids in the polypeptide chain coded for by the mRNA.
Answer:
404 amino acids
Explanation:
The translation is the process by which a messenger RNA (mRNA) molecule is used as a template to synthesize a protein in the ribosomes. During translation, each triplet of nucleotides or 'codon' determines one specific amino acid of the growing polypeptide chain (i.e., the protein). In this case, the length of the fully processed AURKA mRNA consists of 1,212 nucleotides, thereby the length of the polypeptide chain will be 404 amino acids (protein length = 1,212 / 3 = 404 amino acids).
Nathan is an ecologist. He’s studying the effect of secondary consumers on primary consumers. His current research focuses on a population of blue jays and crows. They eat caterpillars and mice. If the number of blue jays increases, what are the likely effects on other populations?
AThe number of crows will increase.
BThe number of mice will decrease.
CThe number of mice will remain the same.
DThe number of caterpillars will decrease.
If the number of blue jays increases, the likely effect on other populations is that the number of mice will decrease.
What is the likely effect on other populations if the number of blue jays increases?
If the number of blue jays increases, they will likely eat more caterpillars, which could decrease the population of caterpillars. This could have a negative impact on the population of mice since they also rely on caterpillars as a food source. Therefore, the number of mice is likely to decrease.
Additionally, with fewer mice available, the population of crows that also feed on mice may also decrease, so the number of crows will likely remain the same or decrease. Therefore, the most likely effect on other populations would be B. The number of mice will decrease.

bees and explain completely how the population is changing.
Answer:
Bees are small flying insects, buzzing around with its painful stings which always make people afraid and annoyed. What generally relate with bees are their roles in pollination and producing honey and beeswax. So it seems that bees might be nothing to human as it’s easy to find substitutes for honey as flavoring. However, this perception is mistaken. Without bees, aftermath.
Over the past decade bee populations have been dropping drastically. A 40% loss of honeybees happened in the U.S. and U.K. lose 45% of its commercial honeybee since 2010. This is a phenomenon known as Colony Collapse Disorder (CCD) in which worker bees from a beehive abruptly disappear in a short time. These data are definitely not meaningless since bees are a crucial part of the reproductive cycle of many foods. The impact bees have on the agriculture and the environment is far more crucial than we may think. Crops rely on bees to assist their reproduction and bring them life. Bees are renowned in facilitating pollination for most plant life, including over 100 different vegetable and fruit crops.
