Explanation:
All living organisms (plants and animals) are made up of cells which are the structural and functional unit. This is because it is the basic organizational unit of life. These cells are made up of structures known as the CELL ORGANELLES. The present or absence of one or more of these organelles creates the difference seen in plant and animal cells. They are briefly describe below:
--> Golgi bodies: they are stack membrane-lined sacs which export materials like enzymes and hormones made from the cell.
--> Cell membrane: this is a flexible membrane made up of protein and lipids that prevents the cell contents from escaping
--> Lysosomes: They are small round sacs that contain digestive enzymes which break down substances.
--> Nucleus: This is the largest and the most important cell organelle. It contains a thread-like network of chromatin granules which is extended to form the chromosomes. The chromosomes contain DNA( which is the molecule that houses the hereditary information of the cell).
--> Mitochondria: this is the site of chemical energy conversions for all cell activities. It is thus often called 'power house'.
--> Vacuole: this acts as a store house for many substances including excretory products.
--> Endoplasmic reticulum: these functions to distribute proteins and other materials throughout the cell.
--> Ribosome: these are sites for protein synthesis. They are found free in the cytoplasm or attached to the endoplasmic reticulum.
How do restriction enzymes work?
Explanation:
Like all enzymes, a restriction enzyme works by shape-to-shape matching. When it comes into contact with a DNA sequence with a shape that matches a part of the enzyme, called the recognition site, it wraps around the DNA and causes a break in both strands of the DNA molecule.

What evolutionary advantage does compartmentalization of core metabolic processes offer eukaryotes?
Answer:
Compartmentalization increases the efficiency of the process of cellular respiration, leading to higher energy production (ATP).
Explanation:
In biology, compartmentalization refers to the formation of separate areas within the cell in order to carry out specific cellular functions more efficiently. In a cell, these compartments are usually delimited by lipid layer membranes. In eukaryotic cells, mitochondria (and also chloroplasts in plants) are the most important compartments in terms of metabolic processes. These organelles function to generate energy in the form of ATP by the process of cellular respiration. From an evolutionary perspective, compartmentalization increases the surface area that mitochondria use to generate energy ATP and provides a unique internal medium to carry out these metabolic reactions since oxidative phosphorylation, which the most important process in terms of energy generation, occurs in the mitochondrial matrix.

- Has resources to support analysis at the DOE-JGI site.
- Can identify microbiologic organisms without traditional isolation and culturing of individual organisms.
Explanation:
Metagenomics can be defined as the study of whole genomes of biological communities recovered from environmental samples. This genomic field has enabled the discovery of new species (microorganisms) and their effects on the environment. Next-Generation Sequencing (NGS) technologies allow to obtain huge amounts of genomic data, which has been a limitation in genomics and metagenomics. Metagenomic NGS (mNGS) is a technique used for sequencing nucleic acids present in a biological sample containing mixed populations of microorganisms. Finally, the Department of Energy Joint Genome Institute (DOE JGI) is a referent in metagenomic analysis, especially in genome assembly data obtained from microbial communities. This Science User Facility has developed a series of bioinformatics tools and databases in order to analyze metagenomic information.

Histone proteins are among the most highly conserved protein in eukaryotes. Histone H4 proteins from a pea and a cow, for example, differ in only 2 of 102 amino acids. However, comparison of the two gene (nucleotide) sequences shows many more differences. These observations indicate that mutations that change amino acids must be selected against.
Required:
Why do you suppose that amino acid-altering mutations in histone genes are deleterious?
Answer:
nucleosomal histones (H2A, H2B, H3 and H4) strongly interact among them and with DNA in order to form nucleosomes. In consequence, it is expected that mutations in histone genes have deleterious effects on the organization of the chromatin
Explanation:
Nucleosomes are well known to be the basic structural units of DNA packaging in eukaryotic cells. Each nucleosome consists of an octamer of histone proteins, i.e., two copies each of the histones H2A, H2B, H3, and H4, and one segment of DNA wrapped around this octamer of histones. Chromatin organization is fundamental o regulate key cellular processes, including gene expression and genome maintenance. In consequence, it is expected that histone proteins are evolutionary well conserved across the eukaryotic kingdom.

A. its close proximity to the sun.
B. its dense atmosphere.
C. its heavy, rocky, water-less terrain
D. the absence of a thick atmospheric layer to regulate temperature.
Answer:
D. the absence of a thick atmospheric layer to regulate temperature.
Explanation:
Mercury is the smallest and closest planet to the Sun. On its surface, Mercury's temperatures are extreme, reaching up to 600 ºC in the daytime and dropping to around -180 °C in the nighttime. This huge variation in Mercury's surface temperatures is due to the fact that this planet doesn't have an atmosphere to retain the heat at the night. Therefore, the heat during sunlight hours cannot be distributed on the surface of this planet, and temperatures at the poles can be hundreds of degrees below zero.

If a fresh cucumber slice is placed in very salty water, which direction will the water move, into the cells of the cucumber or out of the cucumber?
If we sprinkle salt on cucumber slices, it releases water after some time due to the process of osmosis. Osmosis is a process where solute or salt from higher concentration moves towards lower concentration through a semi-permeable membrane. Here, in this case, the salt concentration is more outside on the cucumber slices. The individual cell membrane of cells present in cucumber slices acts as a semi-permeable membrane. Inside the cucumber cells, there is less concentration of salt or solute and more concentration of water. Therefore, the salt from outside goes inside individual cells and the water comes out as it also travels from higher concentration to outside lower concentration through a semi-permeable membrane.
