Answer:
The mRNA will contain intron sequences and eventually be translated into a non-functional protein.
Explanation:
Splicing is the last stage involved in mRNA processing (the first two being 5' capping and polyadenylation). A mRNA transcript (result of transcription) contains both protein-coding regions (exons) and non-coding regions (introns). Splicing involves the removal of the introns from the mRNA sequence (by spliceosomes) and the rejoining of the exons.
If the site where splicing process should occur were mutated and splicing does not take place, this means that the introns will not be removed from the mRNA sequence, hence, the final transcript will contain both protein coding and non-coding regions.
If translation (synthesis of protein) eventually occurs, the mRNA that didn't undergo splicing will be translated into a protein molecule that is not functional. This is because the non-coding sequences will interfere with the reading frame of the coding sequences.
21. Name a structure that is in the medial part of the body, located inferior to the lungs and posterior to the intestines. Note: A coronal section would contain this structure and the heart, and it is more caudal than the pancreas.
Answer:
Kidney
Explanation:
The kidney is in the medial part of the body, located inferior to the lungs and posterior to the intestines.
The kidney is the most important excretory organs of vertebrate, which receives blood from the dorsal aorta through the right and left renal arteries and sends out blood through the right and left renal veins. The transverse section of the kidney shows an outer cortex, beneath which is the Medulla and beneath the Medulla, the hollow pelvis of the kidney.
The cortex and the Medulla consist of thousands of nephrons, which are the kidney's structural and functional units. Each nephron consists of a Bowman's capsule, also called renal corpuscle or malpighian corpuscle, with its network of blood capillaries called glomerulus within it. The remaining part of a nephron is a tubule consisting of three distinct portions, i.e., the proximal convoluted tubule, the U-shaped loop of Henle, and a distal convoluted tubule.
The tubule then leads into the pelvis of the kidney via the collecting tubules. The cortex contains only the renal corpuscle and the convoluted tubules, while the Medulla contains the loop of Henle and the collecting ducts. Ultrafiltration of the blood occurs in the Bowman's capsules, and glucose, amino acids, and large amounts of inorganic ions are reabsorbed at the proximal convoluted end from the glomerular filtrate. The sodium salt is actively transported out of the fluid as it passes through the loop of Henle, and finally, water is reabsorbed from the fluid at the distal convoluted tubule and the collecting ducts.
From here, the filtrate passes through the pelvis into the urinary bladder via the ureter. When the bladder becomes full, the urethral sphincter guarding the outlet relaxes so that urine flows out through the urethra.
Urine contains urea, water, and sodium chloride in addition to other compounds. In the presence of antidiuretic hormone, dilute urine is produced. Kidney stones are solid particles formed in the kidneys, which can block kidney tubules.
In the carbon cycle, all animals must consume
other organisms because
A. they can not absorb enough carbon from water.
B. they cannot absorb carbon directly from the air.
C. they are in competition with plants for available
carbon.
D. they require carbon to perform photosynthesis.
Answer:
B. they cannot absorb carbon directly from the air.
Explanation:
Carbon cycle refers to the series of processes through which carbon is exchanged between living and non living components of the environment. During the carbon cycle, animal organisms feed on one another in order to obtain energy, a characteristics that makes them HETEROTROPHIC.
Unlike plants, animals cannot perform photosynthesis, which turns solar energy into biomass (carbon-based). Plants get their carbon source (CO2) directly from air via the stomata on their leaves. Animals, on the contrary, cannot get carbon this way, hence, they need to feed on other animals to get their carbon and energy source.
What of the following statements is true of a microbiome?
In the crystal matrix of ordinary salt, the sodium and chlorine are held together by:_______
A. peptide bonds.
B. covalent bonds.
C. ionic bonds.
D. hydrogen bonds.
E. nonpolar bonds.
Answer:
C. ionic bonds
Explanation:
In the crystal matrix of ordinary salt, the sodium and chlorine are held together by: ionic bonds.
Ionic compounds result from electrostatic interactions between ions, which often results from the net transfer of one or more electrons from one atom or group of atoms to another, that is, it is the attraction of oppositely charged ions (cations and anions) in large numbers to form a solid. .
Sodium chloride is an ionic compound made up of family 1 sodium metal and the nonmetal chlorine.
When sodium gives up its valence electron, the positively charged sodium ion is produced; chlorine accepts this electron and the negatively charged chlorine ion is formed.
The two ions have 8 electrons in their outer shell and attract each other, as they have opposite charges. The resulting compound is electrically neutral, that is, it has no charge.
Ionic compounds are crystalline solids, soluble in water, and conduct electricity when molten or in solution. These characteristics are due to the type of bond that holds them together.
Therefore, we can conclude that common salt is an ionic compound because it is made up of cations and anions, where the sodium and chlorine are held together by ionic bonds.

How many years of cumulative evolution separate chimpanzees from humans?
A. 7-8 million years
B. 2-3 million years
C. 130-140 million years
D. 130-140 thousand years
E. 14-16 million years
Answer: A. 7-8 million years
Explanation:
Chimpanzees are considered the closest species to humans and so a logical question to ask is why they haven't evolved as well or rather why they are still chimps and we are human.
The reason is that our ancestors split and went on different evolutionary paths. This split happened sometime 7 - 8 million years ago which therefore represents the years of cumulative evolution that separates chimpanzees from humans.

what structural differences makes adenine and guanine different from cytosine, thymine, and uracil? (figure 2-24)
Answer:
Nitrogenous bases have two distinct families known as purines and pyrimidine, nitrogenous are the building blocks or monomer units of the nucleic acids.
The major and significant difference between purines and pyrimidines is the difference in their structures-
The purines are divided into two different bases called adenine and guanine and each of them have a two-ringed structure formed with a 9-membered molecule and 4 nitrogen atoms which makes it a large in size than purines.
The pyrimidines are divided into 3 bases that are cytosine, uracil, and thymine and all these have only one single ring of six members and 2 nitrogen atoms. These are smaller in size.

In 3.a (above) you mutated one letter. What role do you think the redundancy of the genetic code plays in this type of change?
Answer:
It has a role of mutation and eventual evolution in the field of genetics.
Explanation:
The changing of one letter represents whether or not the amino acid encoded by the triplet base will be affected. Redundancy in code means there are multiple codes that will be translated to the same amino acid, so a change/mutation in that position does not alter the protein produced.

Which independent variable affected the organism’s health positively in each of the trials? Why do you think this occurred?
Answer:
Please see below
Explanation:
The variable that had the most affect was the salinity. The sea animals have a tough time trying to survive under highly saline sea water, as this upsets their internal environment as well, in turn affecting their bodily functions and overall health too. The reason behind this was probably that they were used to an environment of high levels of salinity and low levels of light.

H. Initiates motor output
I. Produces heat
J. Produces blood cells
1. Skeletal System
2. Muscular System
3. Nervous System
4. Endocrine System
5. Reproductive System Reset
Answer:
Helps regulate metabolism- Endocrine System.
The production of certain hormones regulate the process of digestion.Gastrin,secretin and cholecytokinin are the hormones of the alimentary canal which regulate digestion. In addition,testosterone,oestrogen,progesterone,and sugar regulatory hormone -insulin are other hormones involved in metabolism.
Produces hormones-Endocrine System
This contains certain gland which secretes hormones directly into the blood stream,to be carried to the target part of the body.The endocrine glands are located in different part of the body;The hormones secreted are proteins or cortisol.
Supports the body-Skeletal System
This is the system which contains bones and cartilages for the attachment of ,muscles for locomotion and stability.it form the framework of the body.Therefore the interaction of the muscles and bones is refers to as the skeletal muscular system.The bones can not provide support without the presence of muscles.
Produces heat-Muscular System- this stems from shivering.it refers to spasmodic contraction of the muscles due to drop in body temperature to generate heat.it is an auto-regulatory mechanism to rise the body temperature when this drops below baseline.
Differs in males and females-Reproductive System
This is designed the male organ as an intromittent organ(Penis) with two testis for sperm production,and the opening as(Virginia) in female
Maintains posture - Muscular System.
it is the contraction and relaxation of the muscles which ensures posture.The musculo-skeletal systems which ensures posture,stability in animals ensures the bones and muscles are aligned.
Produces gametes-Reproductive System-Ovaries in females and testis in males are the sites of ova and sperms respectively as the gametes
Receives sensory input- Nervous System- the PNS send sensory inputs to the CNS for coordination of the Nervous system.These inputs are sent from the receptors.
Produces blood cells-Endocrine System
This is exemplified with the thymus which helps in the production of white blood cells,from its location in the neck
