Explanation:
Sister chromatids
During DNA replication the chromosomes contract and the identical halves are called sister chromatids.
What is DNA replication?A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication.
Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
In prokaryotes, DNA replication takes place in the cytoplasm, whereas it happens in the nucleus in eukaryotes.
Before dividing, cells must copy their DNA. This promotes successful inheritance of genetic features by giving each daughter cell a copy of the genome.
The two identical copies of the DNA that are produced as a result of this replication are known as "sister chromatids," and they are connected to one another by a section of the chromosome known as the centromere.
Thus, the identical halves of chromosome is sister chromatid.

How do the properties of water and the ability to modify the rates of chemical reactions enable living things to carry out functions necessary for life, such as digesting food?
Answer:
A chemical reaction is a process that changes some chemical substances into others. It involves breaking and reforming chemical bonds. They follow the Law of Conservation of Matter.
Explanation:
Energy is a necessity for all living organisms to survive, and ATP is a reactant that powers several other chemical processes inside cells. Cellular respiration is the method used by cells to produce energy.
What attributes of water are requisite for an organism?The term “universal solvent” refers to water's enormous capacity to dissolve a wide range of molecules, and it is this capacity that makes water such a priceless life-sustaining agent.
Water has five key characteristics: strong polarity, high specific heat, high heat of vaporization, low solid density, and affinity for other polar molecules.
The process of converting one chemical substance into another is known as a chemical reaction. Chemical bonds are broken and rebuilt in this process. The Law of Conservation of Matter is observed by them.
Therefore, Water's function as a solvent aids cells in the transfer and utilization of chemicals like oxygen and nutrients on a biological level.

Photosynthesis and cellular respiration have a unique relationship in that the products of one process are the reactants of the
other. For example the reactants of photosynthesis are also products of cellular respiration. Select ALL of the molecules that are
produced in cellular respiration and are reactants in photosynthesis.
A)
water
B)
oxygen
glucose
D)
sunlight
E)
carbon dioxide
о
BI
C
BD
Answer:
B) Oxygen and E) Carbon Dioxide
Explanation:
Cellular respiration has a general chemical equation as:
[tex]C_6H_{12} O__6[/tex] [tex]+6O_2[/tex] ⇒ [tex]6CO_2[/tex] [tex]+6H_2O[/tex]
glucose + oxygen ⇒ carbon dioxide + water
Photosynthesis has a general chemical equation as:
[tex]6CO_2[/tex] [tex]+6H_2O[/tex] ⇒ [tex]C_6H_{12} O_6[/tex] [tex]+ 6O_2[/tex]
carbon dioxide + water ⇒ glucose + oxygen
Reactants are on the left side of the equation while products are on the right. You can see that the products in cellular respiration are carbon dioxide and water, these also are the reactants in photosynthesis. So (B) Oxygen and (E) Carbon dioxide are the answers.
Answer:
The answer is Water and Carbon Dioxide

explain the importance of meiosis in the life cycle and evolution of the water mold?
Answer:
The diploid form of the mold is called the zygospore, which is were meiosis occurs. Some protists life cycles switch between diploid and haploid phases. This is known as alteration of generations. The water mold reproduces asexually by producing spores, which are diploid. The water mold reproduces sexually by producing gametes which are haploid.
Explanation:
Answer:
Meiosis is important because it ensures that all organisms produced via sexual reproduction contain the correct number of chromosomes. Meiosis also produces genetic variation by way of the process of recombination.

red-green colorblindeness occurs more commonly in men than it does in women. using this information, which chromosome do you suppose the gene for red-green colorblindness resides on, and is the trait dominant or recessive?
Answer:
Usually the Y chromosome. It is recessive because if one Y chromosone is mutated with red-green colorblindness and the X is not, the child will have colorblindness. But, if one X chromosome has the mutation and the other X does not, they will cancel out, meaning the child will not have colorblindness.

What are cell organelles ?
Cell organelles are specialized structures who's function is to perform various jobs inside the cell. These can be found in either prokaryotic or eukaryotic cells.
Eukaryotes are two membrane bound structure i.e. have cell wall and cell membrane. They contain organelles who are also double membraned in nature for e.g. mitochondria and nucleus.
Apart from these mitochondria and nucleus can undergo DNA replication independently due to presence of DNA . Mitochondria generate most of the chemical energy required to power the cell's biochemical reactions. And nucleus contain genetic information along with instructions required for cellular processes.

what is a chain of molecules linked with peptide bonds
Answer:
polypeptide chain
Explanation:
each amino acid unit in a polypeptide is called a residue. A polypeptide chain has polarity because its ends are different, with an α-amino group at one end and an α-carboxyl group at the other.
A chain of molecules connected by peptide bonds forms a polypeptide, a fundamental component of proteins. Peptide bonds are chemical bonds that link amino acids, the building blocks of proteins. This chain structure determines a protein's shape and function.
A polypeptide is made up of a series of molecules connected by peptide bonds and is an essential component of proteins. The coupling of amino acids is made easier by peptide bonds, which are produced by a condensation reaction between the carboxyl group of one amino acid and the amino group of another.
These amino acids, which are the building blocks of proteins, each have a distinct side chain, or R-group, which influences their characteristics. A polypeptide chain's amino acid composition determines the protein's three-dimensional shape, which is essential to its function. This complex link between structure and function emphasizes the importance of peptide bonds in biological processes.

Proteins help Store energy and the genetic code. The long chain of amino acids describes the long chain of polypeptides.
What is protein?
Proteins are among the most prevalent organic molecules in biological systems and have a much wider range of structural and functional variations. Many thousands of proteins, each serving a different purpose, can be found in a single cell.
All proteins are composed of one or more chains of amino acids, despite the fact that their structures and activities differ substantially from one another.
In biological reactions, enzymes function as catalysts, accelerating the reactions. Each enzyme may distinguish between one or more substrates, or the molecules that act as the catalysts for the reactions they catalyze.
Therefore, Proteins help Store energy and the genetic code. The long chain of amino acids describes the long chain of polypeptides.
