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.
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 investigationsWhich 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.
Explanation:
(if this is the apclassroom one lol)
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.
