Which cell structure plays a direct role in the release of chemicals from the cell?
Answer:
The correct answer is - the cell membrane.
Explanation:
When a human cell gets an external stimulus it triggers the production of the specific compound or chemical release which is packed in vesicles from the endoplasmic reticulum and Golgi apparatus to the cell membrane. The cell membrane is the cell organelle that allows or prohibits the entry or exit of any substance.
Chemical release or secretion also depends on the cell membrane and it allows the secretion of chemicals and plays an important role in the secretion of chemical, hormones, or any substance.
Cell membrane is an structure that plays a direct role in the release of chemicals from the cell.
The cell membrane is the wall that cells have, allowing them to remain independent from the external environment.
The membrane has receptors, which are molecules or sets of molecules, capable of recognizing and responding to signals from the extracellular medium, carrying specific information.
When these signals reach the plasma membrane, internal signals are triggered in the cell, both activating and inhibiting different cellular processes and the release of chemicals.
As an example of these external signals we can cite the release of chemicals such as hormones, for example insulin, which increases the synthesis of glycogen.
Therefore, we can conclude that cell membrane is an structure that plays a direct role in the release of chemicals from the cell.

1) c. five
2) a. lysine and arginine
3) g. two
4) d. four
Explanation:
A nucleotide can be defined as an organic molecule which forms the building block of nucleic acid such as deoxyribonucleic acid (DNA) and ribonucleic acid (RNA).
Basically, nucleotide comprises of the following parts;
1. Nitrogenous base: this includes adenine (A), thymine (T), guanine (G), and cytosine (C) which are mainly found in the DNA while adenine (A), guanine (G), uracil (U) and cytosine (C) are found in the RNA.
2. A phosphate group.
3. A penrose sugar: it is either deoxyribose in DNA or ribose in RNA.
The two parts or chemical components of a nucleotide which do not change throughout the structure of DNA are;
I. Five-Carbon Sugar also known as deoxyribose and it has hydrogen on its second carbon.
II. Phosphate: this is the structural backbone that provides support to DNA.
Histones are a group of highly basic proteins that are mainly associated with deoxyribonucleic acid (DNA) in the nucleus of a living organism and then condense it to chromatin.
Histones include five main classes of relatively small basic proteins containing relatively large amounts of lysine and arginine. Nucleosomes are made of two each of four types of histones.

Choose the true statement about prokaryotic and eukaryotic DNA replication. View Available Hint(s) Choose the true statement about prokaryotic and eukaryotic DNA replication. Eukaryotic DNA replication involves less protein factors than does prokaryotic DNA replication. Eukaryotic DNA replication begins at multiple origins of replication, while prokaryotic DNA replication begins at a single origin of replication. Prokaryotic genomes take longer to replicate than eukaryotic genomes. Prokaryotic DNA polymerases replicate DNA 5' to 3', while eukaryotic DNA polymerases replicate DNA 3' to 5'.
Answer:
The correct answer is - Eukaryotic DNA replication begins at multiple origins of replication, while prokaryotic DNA replication begins at a single origin of replication.
Explanation:
There are several differences in the prokaryotic and eukaryotic DNA replication as it takes place in the cytoplasm in prokaryotes whereas it occurs in the nucleus in the eukaryotes. The other difference is that it is a continuous process in prokaryotes but it occurs during the S phase only in eukaryotes.
In prokaryotes, the DNA replication begins at a single origin of replication in both directions and in eukaryotes, DNA replication starts at multiple origins of replication.

The Autonomic Nervous System can be challenging to understand because it is connected to virtually every body function in opposite ways. We are going to explore the physiology of the ANS in this discussion by looking at specific examples of how it works. For your first discussion post, describe how the parasympathetic nervous system influences one function in your body. For example, the parasympathetic nervous system causes decreased blood pressure. If you chose this body function, you would describe the physiology behind the decreased blood pressure. How does it happen? What occurs in the heart/blood vessels? Which scenarios or external factors would cause the parasympathetic nervous system to activate this response?
Answer:
The autonomic nervous system is the main function of our arterial cell function in our body.

What are some Non-examples of a Fossil record?
Answer:
Explanation:
A fossil record is a group of fossils which has been analyzed and arranged chronologically and in taxonomic order. Fossils are created when organisms die, are incased in dirt and rock, and are slowly replaced by minerals over time. What is left is a mineral impression of an animal which once existed. Many fields and specialties are utilized to categorize and arrange these fossils, including comparative anatomy, radiometric dating, and DNA analysis. Using the data from the fossil record, scientist try to recreate phylogenies, or trees describing the relationships between animals, both alive and extinct. The fossil record helps inform how different groups of animals are related through evolution.
Answer:
Fossils are the geologically altered remains of a once-living organism and/or its behaviour. There are two main types: body fossils represent all or part of the organism’s body, and trace fossils show evidence of the organism’s behaviour. The study of fossils is called paleontology, from the Greek meaning ‘ancient (paleo-) being (onto-) study (-logy)’. Scientists who study fossils are called paleontologists. Fossils are of particular interest to geologists as they can help determine the age of a particular rock compared to other rocks, or identify the environment in which the rock was formed.

Write out the steps in the Central Dogma. List where each step occurs in the cell. For each arrow, name the process that the arrow represents and the primary enzyme (complex) respon- sible for completing that step. Name the step(s) in which mRNA, tRNA, and rRNA have a role and briefly describe the role of each in the step(s) you name.
Answer:
1. The Central Dogma refers to the molecular process by which the DNA is converted into proteins using RNA as intermediate, i.e., DNA (Transcription)-> RNA (Translation) -> Protein.
2. Localization:
Transcription: within the cell nucleus (in eukaryotic organisms)
Translation: cytoplasm
3. Enzymes :
Transcription: RNA polymerase
Translation: Peptidyl transferase
Explanation:
Transcription is the process by which a segment of DNA (called gene) is used as template to synthesize a messenger RNA (mRNA) by using a specific RNA polymerase enzyme. During translation, this mRNA travels from the cell nucleus to the ribosomes in the cytoplasm, where this sequence (mRNA) is used as template to synthesize a protein. The ribosomes are organelles composed of ribosomal RNA (rRNA) molecules which direct the catalytic steps of protein synthesis, while transference RNAs (tRNAs) are molecules that act as adaptors which link the mRNA template with the corresponding amino acids being incorporated into the protein. The enzyme peptidyl transferase catalyzes the formation of peptide bonds between adjacent amino acids.

What is the main factor that causes bedrock to weather at different rates?
1. Elevation above sea level
2. Mineral composition
3. Age of rock layers
4. Environmental factors
Answer:
2. Mineral composition
Explanation:
Weathering can be defined as the physical and chemical breakdown of rock into smaller pieces called sediment. Weathering can be classified into two categories namely;
I. Physical weathering : it is the process of breaking rocks into pieces without affecting its chemical composition e.g temperature, abrasion and frost action.
II. Chemical weathering : it is the process of breaking rocks into pieces by chemical action which leads to changes in its chemical composition e.g carbonation, hydration, plant acid and oxidation.
Minerals is any form of naturally occurring, inorganic solid substance characterized by a crystal structure. Also, minerals are homogeneous in nature with a defined chemical composition and characterized by a crystal structure comprising of ions, atoms, or molecules in an orderly arrangement.
Hence, mineral composition is the main factor that causes bedrock to weather at different rates.
