Answer:
Mendel's law of independent assortment states that the alleles of two (or more) different genes get sorted into gametes independently of one another. In other words, the allele a gamete receives for one gene does not influence the allele received for another gene. Let's look at a concrete example of the law of independent assortment.
Explanation:
Oxygen is a product of the electron transport chain.
True or False
Answer:
true
hope this helps you ☺️☺️
Electron transport chain can be defined as the series of organic molecules and proteins which are embedded in the inner membrane of mitochondria. These molecules are involved in the shutting of electrons from FADH2 and NADH to the [tex]O_{2}[/tex].
The molecular oxygen is the final electron acceptor in this electron transport chain that leads to the formation of water and ATP as the end products. This chain takes place in the mitochondria in both animal and plant cells.
Hence, the given statement is true.

gene mutations can occur
a. exposure to chemical mutagens
b. exposure to gamma radiations
Answer:
b
Explanation:
The cell membrane is ----------in nature
a. Highly permeable b. normally permeable c. not permeable d. partially permeable
Answer:
d. partially permeable
Explanation:
The cell membrane is the cellular organelle that covers and bounds all cells. It forms a boundary around a cell, protecting all other organelles. The cell membrane, according to the FLUID MOSAIC MODEL, contains phospholipid bilayer, proteins etc.
The phospholipid (lipid) content of the cell membrane confers its ability to be SELECTIVELY OR PARTIALLY PERMEABLE upon it. It is said to be partially permeable because it allows the passage of some molecules/substances and blocks the passage of others.
Why do mutations code proteins?
Answer:
A nonsense mutation is a genetic mutation in a DNA sequence that results in a shorter, unfinished protein product. DNA is a chain of many smaller molecules called nucleotides. During protein formation, DNA (or RNA) nucleotide sequences are read three nucleotides at a time in units called codons, and each codon corresponds to a specific amino acid or stop signal (stop codon).

Answer:
C
Explanation:
can anyone answer that
Answer:
1. Short-term energy storage
2. Lipids
3. Speed up chemical reactions, support cell's structure
4. Nucleic acids
Explanation:
The image comprising of a tabular representation portrays the four biological molecules, their building blocks and function. The four biological molecules in nature are carbohydrates, proteins, lipids and nucleic acids.
- Carbohydrates are biological polymers made up of monomers called monosaccharides. They function to store energy in cells for a short period of time. Examples are glucose, starch etc.
- Lipids are formed from monomers called FATTY ACIDS. They function in the long term storage of energy. Examples are phospholipids, fats etc.
- Proteins are formed from monomers called AMINO ACIDS. They provide various functions including speeding up of chemical reactions, provide cellular structure support etc. Examples are haemoglobin, melanin, hormones etc.
- Nucleic acids are polymers of NUCLEOTIDES. They function majorly in the storage of genetic information. Examples are DNA, RNA etc.

19. Fresh poultry should be rejected when:
A. It has been shipped in plastic wrap
B. It is slightly sticky to the touch
C. There is no discoloration
D. The receiving temperature is 38°F
Answer:
B
Explanation:
Fresh poultry should be rejected when the receiving temperature is 38°F. Therefore, option (D) is correct.
Poultry must be stored and transported at or below 40°F to guarantee food safety and inhibit the proliferation of harmful bacteria. Exposure to unsafe temperatures during storage or transportation can increase the risk of bacterial contamination and foodborne illness if the receiving temperature exceeds the threshold.
Indicators like plastic wrap during shipment, slight stickiness, or lack of discoloration do not necessarily imply safety concerns or spoilage with fresh poultry, as mentioned in the other options.

A person with a Doctorial Degree in Entomology and a Certificate in Forensic Entomology. Hence option D is correct.
What is Entomology ?Entomology is defined as the investigation of insects and how they interact with people, the environment, and other living things. Entomology is employed extensively in a wide range of fields, including evolutionary biology and medical research, in addition to studying the anatomy and physiology of insects. It aids agricultural entomologists in their research on biodiversity as well as in the protection of priceless resources from insect pests.
Forensic entomology is defined as the study of arthropods, particularly insects, connected to criminal activity and other judicial issues. An essential tool in the examination of homicide, self harm, and other violent crimes is forensic entomology. When properly gathered and examined by skilled forensic investigators, insect evidence found on a victim's corpse can provide important information.
Thus, a person with a Doctorial Degree in Entomology and a Certificate in Forensic Entomology. Hence option D is correct.

The phase of mitosis that is characterized by the disappearance of the nuclear membrane is
Answer:
Prometaphase (late prophase)
Explanation:
Mitosis is the kind of cell division in which two genetically identical copies of a cell is formed from a cell. Mitosis comprises of stages which include prophase, metaphase, anaphase and telophase. Each phase is characterized by specific occurrences that all work together to achieve the main goal of forming two daughter cells.
According to this question, PROPHASE stage is the stage characterized by the condensation of chromatids into chromosomes, the disappearance of nucleolus and BREAKDOWN of NUCLEAR MEMBRANE.

describe how you would test a sample of powdered milk to see if it contained protein
Answer:
How would you contained protein
Explanation:
One would test a sample of powdered milk to see if it contained protein by using copper sulfate solution and sodium hydroxide solution.
What is protein?A structure composed of amino acids. The body need proteins to function properly. They serve as the building blocks for several bodily components, including the skin, hair, and enzymes, cytokines, and antibodies.
An essential component of a balanced diet is protein. Amino acids are the chemical "building blocks" that make up proteins.
Amino acids are used by your body to create hormones, enzymes, and to build and repair muscles and bones. They can be utilized as a source of energy as well.
The test can be done as:
To your meal solution, add a few drops of copper sulfate solution. A few drops of sodium hydroxide solution should be added. Protein is present in the food if the solution becomes purple.Thus, using copper sulfate solution and sodium hydroxide test, one can determine the protein content in the sample.
