What are the first organisms to live within a newly created patch of land called?
Give examples
Ecology
Answer:
Pioneers
Explanation:
This question is related to primary succession, which is the first time colonization of a bare rock by certain organisms called PIONEER SPECIES. In this type of succession, a rock surface where there is absence of soil or vegetation is colonized by these set of organisms known as PIONEER.
These pioneer species greatly aid in the formation of soil in that area in order for other form of lives to inhabit the area. Examples of pioneer species that are adapted to grow on these bare or Rocky surfaces are LICHEN, GRASSES etc.

NS is a 32-year-old female who had been sick with a cold virus for 10 days. She states that she had flu symptoms of cough, sore throat, and fatigue. It has been 3 weeks since the cold, and she continues to be fatigued and finds it hard to get enough energy to do things. NS says she has noted that she has been bruising easily. She hit her arm accidentally on the edge of a counter, and now she has a large bruise. She has also noted little purple spots all over her hands and chest. On exam it is noted that she does have a large bruise on her right arm and petechiae and purpura over her chest and hands. Lab work comes back with a platelet count of 40,000mm^3.
Required:
NS has been diagnosed with idiopathic thrombocytopenic purpura (ITP). Explain what it is and who can get it.
Answer:
Idiopathic thrombocytopenic purpura or ITP is also known as Immune thrombocytopenic purpura that is a disorder in which there is an abnormality in the clotting of blood due to a decreasing number of platelets in an individual.
Platelets plays role in clotting the blood to prevent bleeding so this disorder leads to easy bruising, bleeding gums, and internal bleeding. It is an autoimmune disorder as in this case, an immune reaction takes place against one's own platelets.
It occurs in all age and sex groups however, it occurs normally in young children and females more often.
If a protein will end up with 30 amino acids, how many codons, not including the STOP codon, were on the mRNA
transcript that produced it?
Answer:
30 codons
Explanation:
Translation is the second process of gene expression, which involves the synthesis of amino acid sequence from mRNA. This process occurs in the ribosome where the mRNA is read in a group of three nucleotide bases called CODON. Each codon specifies a particular amino acid.
Since one codon specifies or translates into one amino acid, a protein with 30 amino acids will contain 30 codons (exclusive of STOP CODONS) on the mRNA transcript.

A.Errors in the base sequences will result in a damaged strand of DNA.
B.The base sequences of mRNA can be exactly the same as those on DNA.
C. It is more likely that there will be more errors in coding base sequences in mRNA than there will be in DNA.
D. It is more likely that there will be fewer errors in coding base sequences in mRNA than there will be in DNA.

A strong UREA solution is a common reversible denaturant. Additional treatment with 2-mercaptoethanol completely denatures proteins that contain disulfide bonds.
Denaturing reversible agents can alter the secondary/tertiary structure of a protein without altering its primary structure.Urea is a reversible denaturant that breaks hydrogen bonds in the secondary structure of proteins without modifying the primary structure.2-mercaptoethanol is a denaturing agent that cleaves disulfide bonds between cysteine residues.In conclusion, a strong UREA solution is a common reversible denaturant. Additional treatment with 2-mercaptoethanol completely denatures proteins that contain disulfide bonds.

where does an organism inherit its genetic instructions from
Answer:
Organism's parent.
Explanation:
Trait can be defined as the specific features or characteristics possessed by a living organism. It is essentially transferred from the parent of a living organism to her offspring and as such distinguishes him or her.
Simply stated, a trait refers to the distinguishing characteristic or quality of any living organism.
Some examples of traits in genetics are colorblindness, handedness, curly hair, height, complexion, weight, hair color, dimples, tongue-roll, etc.
For example, John is so tall and has a curly hair, it's obvious he acquired the trait from his mum.
In Genetics, a trait comprises of all the genetic instructions that are typically being transfered from the parent to their offsprings.
Hence, an organism inherit its genetic instructions from its parent.

The epithelium's tissue
The human body is made entirely of epithelial tissue. It supports a variety of bodily processes, including defense, secretion, absorption, and filtration.
A unique type of tissue called epithelial tissue can be found in the skin's outer layer.
The small intestine serves as the site of both digestion and absorption. The small intestine contains a straightforward columnar epithelium. The term "digestive epithelium" is sometimes used.
The pseudostratified columnar epithelium is present in the human olfactory mucosa. The skin serves as protection and contains epithelial tissue. The kidney contains glomerulus epithelium, which aids infiltration.
Therefore, the small intestine is where digestion and absorption occur.
