Answer:

a. Lochotrophozora

Explanation:

Molecular research and studies complement morphological research and improve our awareness and knowledge of evolutionary history. Previously, morphological studies could only reveal to us the variations and distinctions, but molecular studies and phylogeny have enabled us to pinpoint the fundamental mechanism of this variation on a genetic level, as well as locate it down to evolutionary lineage, which has led to more enhanced genealogy and evolutionary studies.

However, the group of organisms that best reflects and represents this kind of change is: Lochotrophozora

Groups represent an example of this change is option "A" which is Lochotrophozora.

Lophotrochozoa is a monophyletic group of animals that includes annelids, molluscs, bryozoans, brachiopods, Platyhelminthes, and other animals that descended from the common progenitor of these organisms.

Lophotrochozoa is one of the three major clades that include bilateral animals, or Bilateria.

Thus, option "A" is Lochotrophozora.

Answer:

14. (a) Pb

15. (d) Al

16. (A) increases

Explanation:

14.

In the reactivity series of metals an element can displace another element from a compound if and only if it is not placed below that metal, as the reactivity of metals decreases when moving from top to bottom- if a metal is placed below Hydrogen it means that it is less reactive than Hydrogen and hence cannot displace Hydrogen from its compound.

All options except A are placed below Hydrogen in the reactivity series, so they wont displace Hydrogen from its compound, but option (a) that is Pb can do so as it is above Hydrogen in the reactivity series.

15.

Al is placed below Mg in the reactivity series and hence cannot displace Mg from its compound.

16.

The reactivity of metals increases down the GROUP.

[CAUTION :- We were talking 'bout REACTIVITY SERIES in the top 2 questions where reactivity decreases down the group, but we're talkin' 'bout GROUPS of the periodic table here, where reactivity increases down the group.]

The size of metals increases down the group causing their valence electrons to drift far from the nucleus so that they can be lost easily. The metals have a property of losing electrons so the more electrons it can lose more will be its reactivity.

Hence, reactivity increases down the group.

C. Growth hormone promotes the closure of the epiphyseal plate.

The closure of the epiphyseal plate is NOT an effect of growth hormone (option c).

The epiphyseal plate is a layer of hyaline cartilage between the epiphyses and metaphyses at the ends of long bones.

The epiphyseal plate is completely closed when bone growth is completed (around age 18 to 21 years).

Different hormones (i.e., testosterone and estrogen) released at puberty initiate the closure of epiphyseal plates.

In conclusion, the closure of the epiphyseal plate is NOT an effect of growth hormone (option c).

c. cerebral aqueduct

d. medulla oblongata

e. choroid plexus

f. pons; medulla oblongata; midbrain

g. hypothalamus

h. cerebrum

i. epithalamus

j. cerebrum

k. cerebellum

Explanation:

The brainstem is the posterior part of the brain that connects the cerebrum with the spinal cord. The brainstem can be divided into three parts: midbrain (i.e., mesencephalon), the pons (i.e., metencephalon), and the medulla oblongata (i.e., myelencephalon). The mesencephalon is a region of the brain composed of the tectum and tegmentum, which play fundamental roles in motor movement, auditory and visual processing. The corpora quadrigemina is found at the tectum region of the midbrain. The diencephalon is a small part of the brain located above the brainstem (between cerebral hemispheres); which contains the thalamus, hypothalamus, subthalamus, and epithalamus. In turn, the epithalamus is composed of the habenular nuclei, pineal gland, and the stria medullaris thalami. The cerebral aqueduct is a narrow channel (approx. 15 mm) in which the cerebrospinal fluid flows between the third ventricle and the fourth ventricle. The medulla oblongata is a long stem-like structure located in the brainstem of the brain, just in the place where the brainstem connects the brain to the spinal cord. The choroid plexus is a complex network of capillaries located at the cerebral ventricles of the brain, which serve to produce cerebrospinal fluid through ependymal cells that line the ventricles of the brain. The cerebellum is a major structure of the hindbrain and consists of the cerebellar cortex and a core of white matter having the cerebellar nuclei.

Answer:

homeostasis

Explanation:

Homeostasis has to do with processes that maintain the internal balance within an organism. It can succinctly be defined as the process of regulating an organism's internal environment. The process of homeostasis is very important in the maintenance of important indicators of balance in the body such as body temperature, body pH, etc.

Hence, when blood pH becomes overly acidic, respiration and kidney function change to bring the acidity back to its normal pH level of 7.4. This is a homeostatic response.

Answer:

at what location? the question isnt finished

Answer:

mRNA ⇒ 5'GMU  UAC  AUG  CGG  CUC  AGU  UGA  GGC  GAA  AAA  A 3'

tRNA ⇒                           UAC  GCC  GAG  UCA  ACU

protein ⇒ N - MET   ARG   LEU   SER   Stop - C

Explanation:

In protein synthesis, the ribosome reads mRNA in the 5´ to 3´ direction, and, according to the codons that are being readen, tRNA transfers the correct amino acids to build the polypeptide chain. A codon is a short sequence of three nucleotides that store the genetic information for the aminoacids´ assembly. Each tRNA has two important sites. One of them that couples with the codon of the mRNA molecule, named anticodon. The other site couples with an amino acid. tRNA allows amino acids to align according to the nucleotidic sequence in the mRNA molecule.  

Once the new amino acid links to the growing peptidic chain, the binding between the amino acid and the tRNA molecule breaks. The tRNA is now free to join another amino acid and repeat the cycle.  

The protein is synthesized from the amino terminus to the carboxy terminus, while the added amino acids to the chain are coded by a codon formed by three bases in the mRNA. mARNs also have a start and end codon that are the signals of the synthesis initiation and finish. When the ribosome reaches the end codon, protein synthesis is over.    

Each of the codons represents one of the 20 amino acids used to build the protein. Each amino acid can be codified by more than one codon. From the total 64 codons, 61 codify amino acids, and one of them is a start codon. The left three codons are stopping translation points.

The codons indicating the initiation or stop points during the translation process are:

• The start codon AUG is the most common sequence used by eukaryotic cells and places near the 5´extreme of the molecule.  

• The end codons are UAA, UAG, UGA.

Protein synthesis initiates in the AUG start codon -Metionin-, and ends when reaching either of the stop codons UAA, UAG, UGA.

In the exposed example we have the following mRNA.

mRNA ⇒ 5'GMU  UAC  AUG  CGG  CUC  AGU  UGA  GGC  GAA  AAA  A 3'

Codons are separated by a space left between them. AUG is the start codon placed near the 5´ extreme. UGA is the end codon near the 3´ extreme. tRNA will add amino acids from the start codon, not before.

tRNA ⇒ UAC  GCC  GAG  UCA  ACU

Anticodons are separated by a space left between them.

protein ⇒ N - MET   ARG   LEU   SER   Stop - C

Each mRNA codon codifies for an amino acid. The start codon codifies for methionine. AUG = Met, CGG = Arg, CUC = Leu, AGU = Ser, UGA = Stop codon. The amino terminus is represented as an N and the carboxy terminus is a C. The first extreme to be translated carries the amino-terminal group, while the other extreme carries the carboxy-terminus group.
