Answer:
This is an example of scope creep.
Explanation:
In project management, scope creep signifies the changes, uncontrolled or continuous growth in the scope of a project, at any time after the initiation of the project. This can take place when the project's scope is not adequately documented, defined, or monitored.
The main reasons for scope creep are poor requirements analysis, underestimating the complexity of the project, not involving users early enough, and lack of change control. Thus, the given case is an illustration of scope creep.
After transcription begins, several steps must be completed before the fully processed mRNA is ready to be used as a template for protein synthesis on the ribosomes.
Which three statements correctly describe the processing that takes place before a mature mRNA exits the nucleus?
a. Noncoding sequences called introns are spliced out by molecular complexes called spliceosomes.
b. A cap consisting of a modified guanine nucleotide is added to the 5' end of the pre-mRNA.
c. Coding sequences called exons are spliced out by ribosomes.
d. A translation stop codon is added at the 3' end of the pre-mRNA.
e. A poly-A tail (50-250 adenine nucleotides) is added to the 3' end of the pre-mRNA.
Answer:
B
Explanation:
This may be rong, however I think this needs to happen before the mRNA can leave the nucleus. The cap helps prevent the mRNA from being destroyed by the cell itself once it leaves the nucleus.
The time period during which an organ is coming ""on-line"" during pre-natal development is referred to as the:________.
Answer:
Embryonic period
Explanation:
During Prenatal development, the development of an organism takes place in three stages
1) Stage I – When the organism is at the stage I i.e the germinal stage a zygote is formed after a sperm fuses with an egg. The mass of cell move through the fallopian tube and gets embedded in the uterus wall. This process is called implantation.
2) Stage II – In the second stage i.e Embryonic Stage major organs start developing and come in line. After this stage, the embryo is one inch long.
3) Fetal stage – Sex organ, bone, muscle start forming.
Comparing the body structures of organisms to find evidence of a shared evolutionary history is called ________.
A) outgroupingB) relativistic physiologyC) comparative anatomyD) analogous reconstruction
Answer:
The correct answer will be option-C
Explanation:
Comparative anatomy is the branch of study which studies anatomy or skeletal structure of the different species and comparing them to study the relationship between them.
The comparative anatomy is studied to study the evolutionary relationship between the different species which acts as evidence of the evolution. The study has distinguished the skeletal structure as homologous structures or analogous structure.
The correct answer will be option-C.
Comparative anatomy is the term for comparing body structures of organisms to find evidence of shared evolutionary history. It's an essential concept in evolutionary biology and provides evidence of common ancestry and evolutionary processes.
Explanation:The term for comparing the body structures of organisms to find evidence of a shared evolutionary history is called comparative anatomy. This concept is vital in the field of evolutionary biology, where scientists examine the physical features of different organisms to establish common ancestors and track the process of evolution. For instance, the similar bone structures in the forelimbs of humans, bats, and whales suggest a common lineage, even though these limbs perform different functions in each organism.

Which of the following best describes how mitosis and meiosis result in daughter cells with different numbers of chromosomes?
Answer:
In Meiosis, cells are divided twice to the give haploid cells ( four cells) with half the number of chromosomes in the original cell, while in mitosis, cells only divide once to give identical cell with the same number of chromosomes as its origin.
Explanation:
Meiosis is a process where a cell divides to give four cells, with the chromosomes half of that of the original cell. This cell division helps produce your genital cells like sperm and female egg. There are nine stages in meiosis.
Mitosis is a process of cell division where a single cell divides just once to produce two identical cells with the same number of chromosomes as the original cell.
Answer:
D. Mitosis produces two identical diploid daughter cells after one round of division. Meiosis produces four haploid daughter cells after two rounds of division.

The term diverticulosis refers to a condition characterized by:_____A. Polyps or growths on the colon wall.B. Inflammation of small pockets in the colon wall.C. Acquired herniations of the muscular colon wall mucosa and submucosa.D. Congenital herniations of the muscular colon wall mucosa and submucosa.
Answer:
C. Acquired herniations of the muscular colon wall mucosa and submucosa
Explanation:
Hernia refers to the development of outgrowth or protrusion of all or part of the organs through their cavity walls or membrane. Diverticulosis is herniation of mucosa and submucosa of the wall of the colon. Diverticulosis is one of the conditions caused by the imbalance of homeostasis. Many sac-like outgrowths develop in the wall of the colon. The outgrowths are in the form of pouches and are called diverticula.
The out-pouching occurs where the muscularis layer of the wall of the colon has weakened. The people with diverticulosis may have no symptoms and no complications. However, when diverticulosis causes inflammation, the person experiences several complications such as pain, vomiting, nausea, etc.
Which of the following best describes why invertebrates isn't considered a scientifically valid word when classifying animals? A. The term invertebrates describes all animals, so is not helpful in classifying organisms within the animal kingdom. B. The term invertebrates is unhelpful because all animals possess some sort of backbone or notochord. C. The term invertebrates classifies animals haphazardly based on a missing characteristic rather than a common one. D. The term invertebrates is too vague, since all animals evolved from single-celled organisms without a backbone.
Answer:
Option C
Explanation:
In general vertebrates are organism that has backbone/spine or a vertebral column derived from notochord. While invertebrates are organism that do not have any backbone or vertebra column.
All classification terminologies categorize animals or plants on the basis of some common characteristics. However, in the case of this word invertebrate there is no categorization on the basis of common characteristics, it simply distinguish animals from each other on the basis of presence of backbone/spine/notochord.
Hence, option C is correct
Answer:
Option C
Explanation:
When would it be important for a scientific investigation to be replicated
Answer:
To check the accuracy of claims from the investigationsTo see if the outcome of the investigation is applicable to a variant populationTo see if there are gaps in the procedures or results that can provoke further investigationsExplanation:
Replication is the reproducibility of results from scientific investigations. In order for the outcome of an investigation to be deemed correct, the outcome must be reproducible under somewhat similar conditions.
Replication of scientific investigation is important for a number of reasons:
To check the accuracy of claims from investigationsTo see if the outcome of a particular research is applicable to a variant populationTo see if there are gaps in the procedures or results that can provoke further investigationsWhat groove separates the frontal lobe from the parietal lobe?
Answer:
The large deep groove or indentation that separates the parietal and frontal lobe is the central sulcus.
Explanation:
The central sulcus, one of several grooves seen between folds of the cerebral cortex, lies between the frontal and parietal lobes. It separates the parietal and frontal lobes.

In humans, the maintenance of a stable internal temperature is a direct result of___________.
The given question is incomplete. The complete question is:
In humans, the maintenance of a stable internal temperature is a direct result of___________.
a. detection of and reaction to stimuli in the environment
b. digestion of starches and absorption of protein from the internal environment
c. diffusion of water and excretion of glucose to the external environment
d. transport of ATP and locomotion through the environment
Answer:
a. detection of and reaction to stimuli in the environment
Explanation:
Thermoreceptors present in skin layers of the human body sense the deviation of the body temperature from the normal range. As the body temperature rises above normal, the thermoreceptors send signals to the brain which n turn signals dermal blood vessels to dilate and sweat glands to secrete sweat. The heat from the body surface is lost to the surroundings to drop the body temperature towards the normal range.
On the other hand, when the body temperature goes below the normal range, thermoreceptors send signals to the brain which in turn signals dermal blood vessels to constrict to conserve the body heat. If body temperature continues to drop, muscles are signaled to contract involuntarily to generate body heat to raise the body temperature towards the normal range.
