Some scientists claim recent evidence suggests birds should be reclassified to share more taxonomic groups with dinosaurs. The liable options seems evidence showing birds shared a common genetic history with dinosaurs. The correct answer is option D.
What is the class of birds ?It is the class aves that belong to the kingdom Animalia.
The birds and the dinosaurs have the same genetic history that is the phylogenetic relationship of both the species is almost same and they both show a similar set of characteristics.
They had multiple set of characteristics that were similar to both and they shared the common characteristics. The points are written as following :
1.Egg Laying
2.Scales
3.Feathers

Describe methods of replication and protein synthesis in bacteria and viruses.
How does this differ from eukaryotes.
Answer:
Explanation:Unlike bacteria, viruses can't survive without a host. They can only reproduce by attaching themselves to cells. In most cases, they reprogram the cells to make new viruses until the cells burst and die. In other cases, they turn normal cells into malignant or cancerous cells.
List 2 organelles found in an animal cell and explain how those 2 organelles benefit the cell.
Answer:
I chose nucleus and the mitochondria
Explanation:
The nucleus is particularly important among eukaryotic organelles because it is the location of a cell's DNA. Two other critical organelles are mitochondria and chloroplasts, which play important roles in energy conversion and are thought to have their evolutionary origins as simple single-celled organisms.

Cell includes a cell membrane, cytoplasm and cell organelles. Cell organelles are mitochondria, golgi bodies, nucleus, ribosomes, vacuoles, lysosomes, centrioles, etc.
What are cell organelles?Cell organelles are the structures present in cell that are responsible to carry out necessary processes and maintains homeostasis.
This can include nucleus, mitochondria, golgi bodies, ribosomes, etc.
Nucleus: Nucleus is a membrane bound cell organelle that contain an entangled thread like structure called as chromatin material. This chromatin material condenses at the time of cell division and forms chromosomes. Nucleus also contain nucleolus that helps in formation of ribosomal units. it contains a fluid called as nucleoplasm.Ribosome is the organelle that is involved in formation of protein. It has two subunits i.e. a smaller one and a bigger one. these subunits are joined at the time of protein synthesis and are formed in nucleolus of nucleus.
Thus, these were explanation of two cell organelles along with their explanation.

Why do the different genetic types of albinism result in a similar phenotype?
Answer:
Why are there different variations of albinism and why it results in the same basic phenotype?
The phenotypic heterogeneity of albinism is due to the different gene mutations affecting various points along the melanin pathway, resulting in varying degrees of decreased melanin production. Additionally, associated developmental changes occur in the optic system as a result from this hypopigmentation.

How many sugar phospha te backbones are in one strand of DNA?
Answer: Two
Explanation: In double-stranded DNA, the molecular double-helix shape is formed by two linear sugar-phosphate backbones that run opposite each other and twist together in a helical shape. The sugar-phosphate backbone is negatively charged and hydrophilic, which allows the DNA backbone to form bonds with water.

When humans perspire, water, urea, and salts containing sodium are removed from the blood. Drinking water during extended periods of physical exercise replenishes the water but not the sodium. This increase in water dilutes the blood and may result in the concentration of sodium dropping low enough to cause a condition known as hyponatremia. Symptoms of hyponatremia include headache, nausea, and lack of coordination. Left untreated, it can lead to coma and even death. The body has a variety of feedback mechanisms that assist in regulating water and sodium concentrations in the blood. The kidneys play a major role in these mechanisms, as they filter the blood and produce urine. The best way to reduce the symptoms of hyponatremia would be to
Answer:
The best way to reduce the symptoms of hyponatremia is to replace the body's sodium.
Explanation:
As seen in the question above, sweating causes the body to lose water and salts, such as sodium. We know that the excess of sodium in the body is harmful, however, the lack of sodium is also harmful, and can cause hyponatremia.
The loss of water in sweating can be reversed with water intake, but the loss of sodium must be reversed with sodium intake and the best way to do this is by eating salty foods. Sodium is one of the components of the salt used in the preparation of foods. In that case, when an individual eats salty foods, after having lost sodium molecules in perspiration, he will be replacing the lost sodium.

1.) what is the optimal pH for pepsin? where is pepsin found?
2.) what is the optimal pH for salivary amylase? what substrate does it act on? where is it found?
Answer: 1. The digestive power of pepsin is greatest at the acidity of normal gastric juice (pH 1.5–2.5). 1.0–2.0
The optimum pH for pepsin activity of 1.0–2.0 is maintained in the stomach by HCl. When the pH of the medium increases to values greater than 3.0, pepsin is almost completely inactivated. 2. The optimum pH for the enzymatic activity of salivary amylase ranges from 6 to 7. Above and below this range, the reaction rate reduces as enzymes get denatured. The enzyme salivary amylase is most active at pH 6.8. around 7
Salivary α‐amylase has a short‐lived action. In fact, it is swallowed with chewed food and subsequently inactivated by extremely low gastric pH; amylase in fact has an optimal pH around 7, and the pH of saliva is generally between 6.4 and 7.0.

Which of the following steps happens first during transcription?
A. RNA polymerase reaches the end of the gene.
B. RNA polymerase reaches the beginning of a gene.
C. RNA polymerase pulls apart the double helix.
D. RNA polymerase produces mRNA from DNA.
The correct option for the given question about Genetic transcription is Option B) RNA polymerase reaches the beginning of a gene.
What is Genetic Transcription?It is one among the initial steps in the expression of genes. The transport of genetic information from DNA to proteins occurs sequentially through the processes of transcription and translation. During transcription, just one strand of DNA known as the template strand is replicated, and the resulting RNA is referred to as messenger mRNA.Transcription's primary goal is to create an RNA copy from a DNA sequence. The data required to encode a protein is carried by the RNA transcript.RNA polymerase is the key enzyme responsible for Genetic transcription.It creates a complementary RNA strand from single strand DNA.
Thus we conclude that during the first step of genetic transcription RNA polymerase reaches the beginning of a gene.
