The muscle that originates on the sacrum and transverse process of each vertebra and inserts on the spinous process of the third or fourth more superior vertebra is the ________ muscle. Group of answer choices quadratus lumborum interspinalis semispinalis
Answer:
multifidus muscle
Explanation:
Multifidus is a group of smaller muscles located near the spine (anteriorly among cervical paraspinal muscles) that extend, flex and rotate the spine. This muscle (multifidus) is an important stabilizer of the spine by stabilizing the joints at each segmental level. The multifidus muscle controls the erection of the spine and stabilization during its movements and the movement of the extremities.

After phosphates and nitrates have entered a water
system, identify the correct steps of Eutrophication.
I. Oxygen levels drop
II. Underwater plants die
III. Fish and invertebrates die
IV. Algae grows rapidly
A. II, III, IV, I
B. IV, II, I, III
C. I, III, IV, II
D. III, II, I, IV
After phosphates and nitrates enter a water system, the steps of eutrophication include the rapid growth of algae, death of underwater plant species, depletion of oxygen in the water, and the death of fishes and invertebrates. The correct option would be B.
Eutrophication refers to the excessive enrichment of water bodies by nutrients such as phosphates and nitrates thereby facilitating the rapid growth of some aquatic species with negative effects.
Once a water body becomes excessively enriched with phosphates and nitrates, the following is a sequence of events that follows:
Algal bloom: the nutrients facilitate the rapid growth of algaeThe bloom of algal species results in the death of underwater plants as a result of inadequate light.The death of the underwater plants and the accompanying microbial activities in decomposing them cause oxygen levels in the water to drop.Reduction in oxygen level causes fishes and other water invertebrates to die due to hypoxiaTherefore, the correct steps of eutrophication according to the illustration is IV, II, I, and III.

A garden has a length of 1.5 x102 m and a width of 0.5 x 102 m. what is the area of the garden?
Answer:
7.5 × 10^3 m^2
Explanation:
The garden described in this question takes the shape of a rectangle, which has a length of 1.5 x102 m and width/breadth of 0.5 x 102 m.
To calculate the area, we use the formula for calculating the area of a rectangle, which is;
Area = length (L) × width (w)
Area = 1.5 x102 m × 0.5 x 102 m
Area = 150 × 50
Area = 7500
This, the area of the garden is 7500m^2 or 7.5 × 10^3 m^2

You are studying lipoprotein processing in a strain of mutant mice. You find that these mice synthesize the same apolipoprotein composition contained in lipoproteins made in the liver and the intestines, whereas, in wild-type mice there are 2 different sized apolipoproteins in these same tissues. Examination of the mRNA processing in the mutant mice would most likely show a defect in which of the following processes?A. alternative polyadenylationB. alternative splicingC. differential cappingD. posttranscriptional modification converting a U to a T residueE. RNA editing
Answer: Option E -- RNA Editing
Explanation:
It should be noted that, RNA editing can be defined as a molecular process via which some cells can make discrete changes to specific nucleotide sequences within an mRNA molecule after it has been generated by RNA polymerase. In addition, we have two major types of RNA editing with 1 being a C-to-U change catalyzed by cytidine deaminase that deaminates a cytidine base into a uridine base, e.g C-to-U editing is with the apolipoprotein B gene in humans. ApoB-100 is expressed in the liver and apoB-48 is expressed in the intestines. The B-100 form comprises of a CAA sequence that is edited to UAA, a stop codon, in the intestines.

Fomites are Group of answer choices insects that transmit pathogens from an infected host to a non infected host. animal sources for human pathogens. inanimate objects involved in the indirect contact transmission of pathogens. fecal material from infected hosts. silent carriers of infectious diseases.
Answer:
Fomites are inanimate objects involved in the indirect contact transmission of pathogens.
Explanation:
Fomites are inanimate objects involved in the indirect contact transmission of pathogens. These objects include a whole range of items mostly found in indoor environments. When pathogens such as viruses and bacteria come in contact with these objects through various human and animal activities such as sneezing or coughing, use of toilets etc; these pathogens remain active on these objects and can then cause disease when others come in contact with these objects.
Common fomites in the home include toilet seats and handles, doorknobs, kitchentops, bed coverings , mobile phones, light switches as well as as toys. In offices, door handles, stairway railings as well as wring materials are common fomites. Especially concerning is the issue of disease transmission by fomites in healthcare facilities since there is constant exposure of surfaces and equipments to various pathogens.
To help prevent the spread of diseases by fomites, regular handwashing and disinfection of commonly touched surfaces is required.

Bile juice dose not contain any digestive enzymes yet it is essential for digestion why so ?explain
Explanation:
Although bile juice does not contain any enzymes, it contains bilirubin and biliverdin. These help to break big fat globules into small globules which is taken to pancreatic juices to be further digested. This is known as emulsification of fat. It also helps in secretion of lipase. Thus it plays an important role because majority of the fat digestion process is carried out by it.

Explanation:
Please write down prearation of perment slides of pollen grains by acetolysis method and study of different pollen characters: study of variation pattern in different taxa.
Answer is given below
Explanation:
Collection and preservation of pollen material: In clean glass pots containing 70% glacial acetic acid, some of the stamens are applied with clean forceps prior to flower synthesis and sometimes protected from diamonds or mature flower buds. Some polyologists recommend 70% ethyl alcohol to preserve feathers in place of glacial acetic acid. In this condition, pollen-filled feathers can be stored indefinitely. The wings are transferred to a centrifuge tube and rinsed well with distilled water.the wings are crushed with a glass rod and the mixture is filtered through a cheesecloth or sieve. The lower part is recalled in the centrifuge tube. A freshly prepared acetolysis mixture containing acetic anhydride and concentrated H2SO4 (sulfuric acid) in a ratio of 9: 1 is poured into a centrifuge tube containing the washed pollen. Care must be taken to connect the conceider. H2SO4 by acetic anhydride drop to prevent overheating. The acetolysis solution reacts violently with water. Glacial acetic acid washers are required to replace water with acetic acid, which does not react violently with the acetolysis solution. Although the acetolysis process varies from pathologist to pulmonologist, the following approach seems to be the most appropriate. From the first to the last acetic acid wash, care is taken regardless of the water solution. Only distilled water should be used for washing to prevent contamination.
