can anyone writet about describing ● History of Ribosomes.
Answers
Answer:
The ribosome is a complex molecule made of ribosomal RNA molecules and proteins that form a factory for protein synthesis in cells. In 1955, George E. Palade discovered ribosomes and described them as small particles in the cytoplasm that preferentially associated with the endoplasmic reticulum membrane. Along with other scientists, Palade discovered that ribosomes performed protein synthesis in cells, and he was awarded the Nobel Prize in 1974 for his work.
Each ribosome has a large component and a small component that together form a single unit composed of several ribosomal RNA molecules and dozens of proteins. The ribosome is responsible for translating encoded messages from messenger RNA molecules to synthesize proteins from amino acids. The ribosome translates each codon, or set of three nucleotides, of the mRNA template and matches it with the appropriate amino acid in a process called translation. The amino acid is provided by a transfer RNA (tRNA) molecule. Each newly translated amino acid is then added to the growing protein chain until the ribosome completes the process of protein synthesis.
Stella described protein synthesis as a process that makes the necessary proteins for the human body to function. She
explained the process in the following steps.
1. DNA is transcribed into mRNA.
2. Amino acids form a chain.
3. The amino acid chain is folded into a protein in the endoplasmic reticulum.
What step did Stella miss in her explanation?
(1 point)
O Polypeptide chains express gene traits.
O tRNA delivers the DNA to the ribosome.
hy
O DNA is replicated into two daughter cells.
O mRNA is translated into amino acids.
Answers
The step of protein synthesis missed by Stella would be the translation of mRNA into amino acids.
The process of protein synthesis can essentially be divided into 2, namely:
TranscriptionTranslationDuring transcription, genetic information on DNA is transcribed into mRNA. Once this is done, the genetic codes in mRNA are then translated to their respective amino acids and linked by peptide bonds.
The polypeptide bond undergoes further processing such as folding in the endoplasmic reticulum.
Thus, before amino acids can form a polypeptide chain, they must first be translated from genetic codes in mRNA.

Describe the activities of DNA and the three types of RNA.
Answers
Answer:
There are three types of RNA: mRNA, tRNA, and rRNA. mRNA is the intermediary between the nucleus, where the DNA lives, and the cytoplasm, where proteins are made. rRNA and tRNA are involved in protein synthesis. Additional RNAs are involved in gene regulation and mRNA degradation.

A plant cell is placed in a salt solution, and the following observation is recorded:
A normal plant cell is on the left. The plant cell wall is visible, and the internal structure fills the cell up to the cell wall. In the middle is an arrow pointing from left to right. On the right is a plant cell. This plant cell has a cell wall the same size as the first plant cell, but the internal structures are shrunken in comparison to the first cell.
Which answer choice describes the most likely concentration of the solution?
Hypertonic
Hypotonic
Isotonic
Osmotic
Answers
Answer:
Explanation:
a simple way to look it it is:
Hypertonic would be when the insides are shrunk (arrows point out)
Hypotonic when its full (Arrows point in)
Isotonic is at balance (arrows point out and in)
osmotic: the passage of a liquid through a membrane from a less concentrated solution to a more concentrated one (equal concentrations)

Which of the following statements accurately describes the relationship between photosynthesis and cellular respiration?
The function of photosynthesis is to use solar energy to make ATP; the primary function of respiration is to break down ATP to release energy.
Photosynthesis only occurs in heterotrophs, while cellular respiration only occurs in autotrophs.
Photosynthesis and cellular respiration occur in separate, specialized organelles, and the two processes cannot occur in the same cell at the same time.
Photosynthesis uses solar energy to create organic molecules; cellular respiration breaks down organic molecules to make ATP.
Answers

If you stained both onion epidermal cells and cheek epithelial cells with methylene blue which would stain more quickly and why?
Answers
Answer:
the nucleus at the central part of the cheek cell contains DNA. When a drop of methylene blue is introduced, the nucleus is stained, which makes it stand out and be clearly seen under the microscope. And methylene blue stains negatively charged molecules in the cell, including DNA and RNA. This dye is toxic when ingested and it causes irritation when in contact with the skin and eyes. The cells seen are squamous epithelial cells from the outer epithelial layer of the mouth.

How does independent assortment increase genetic variation in Meiosis?
Answers
Answer:
Independent assortment produce new combinations of alleles.
Explanation:
In meiosis I, crossing over during prophase and independent assortment during anaphase creates sets of chromosomes with new combinations of alleles. Genetic variation is also introduced by random fertilization of the gametes produced by meiosis. It results in gametes that have unique combinations of chromosomes.

Answers
Modern taxonomy can be used to distinguish how closely related organisms are. It is a branch of systematics used to classify organisms based on different phenotypic traits and characteristics.
Taxonomy is a system of identifying and classifying biological systems.
Modern taxonomy refers to the system of classification of organisms on the basis of their evolutionary relationships (i.e., its basis involves phylogeny).
Modern taxonomy takes into consideration empirical evidence from different fields of study (e.g., morphology, cytology, physiology, etc).

The three ecosystem services that insects provide are dung burial, pest control, and pollination.
What is an ecosystem?Ecosystem is defined as a system which consists of all living organisms and the physical components with which the living beings interact. The abiotic and biotic components are linked to each other through nutrient cycles and flow of energy.
Energy enters the system through the process of photosynthesis .Animals play an important role in transfer of energy as they feed on each other.As a result of this transfer of matter and energy takes place through the system .Living organisms also influence the quantity of biomass present.By decomposition of dead plants and animals by microbes nutrients are released back in to the soil.
