The correct option is D.

The communication system describes an information conversation between different sites. Data is sent and received in communication. The three major parts of communication are the data transmitter, the channel or medium of communication, and the data receiver.

The telephone, the telegraph, the cell phone, the Edison telegraph, the computer, and the TV cable are the key examples of communication systems. This system's sources can be classified as either electric or non-electric. These are the places where a message or input signal comes from.

What is physical observation?

The act of perceiving something and recording it with instruments. A meteorological observation is the result or record of such notation. Clinical observation and inspection are essential components of medical practice. They are essential components of a physical examination because they lead to accurate diagnoses and treatment.

An observation could be, for example, watching an apple fall from a tree. Another observation is that fish only come to a specific section of the river in the early morning.

After an observation is made, it is best to conclude with a simple, unambiguous sentence that identifies the main purpose and correct form of the examination. In this case "most of the girls had brown hair" is the simplest and most correct conclusion.

Explanation:

The example of human genetic mutation and selection resulting from the Neolithic Revolution is the permanent "switch-on" of the lactase gene, prevalent in some populations, which allows humans to digest milk beyond weaning from breastmilk.

During the Neolithic Revolution, humans transitioned from a nomadic hunter-gatherer lifestyle to settled farming communities. This shift brought about significant changes in human behavior, including the domestication of animals for agriculture. One consequence of this transition was the development of the ability to digest milk in adulthood, known as lactase persistence.

Lactase persistence is the result of a genetic mutation that allows the lactase gene, which produces the enzyme lactase necessary for digesting lactose in milk, to remain active into adulthood. In most mammals, including our ancestors, the lactase gene switches off after weaning, making them lactose intolerant. However, in certain populations that have a long history of dairy farming, such as Europeans, some African and Middle Eastern communities, the lactase gene remains active throughout life.

This genetic mutation and subsequent selection were advantageous in societies that relied on dairy farming, as it provided a valuable source of nutrition and calories. Individuals with the lactase persistence mutation could continue to digest milk and its products, giving them a survival advantage. Over generations, this genetic trait became more prevalent in populations with a history of dairy farming, demonstrating the influence of human genetic mutation and selection resulting from the Neolithic Revolution.

Answer:

When kinetic energy is the same the velocity would decrease because mass and velocity are inversely related.

Explanation:

The correct answer is N-terminal uptake-targeting sequence.

The N-terminal uptake-targeting sequence is a short peptide sequence located at the N-terminus of a precursor protein that is targeted to the mitochondrial matrix or chloroplast stroma. This sequence contains all the information required to direct the precursor protein from the cytosol to its final destination within the organelle. The signal sequence is recognized by specific receptor proteins located in the organelle membrane, which then facilitate the translocation of the protein across the membrane through proteinaceous channels called translocons. The C-terminal sequence is not typically involved in organelle targeting, while the thylakoid is a specific organelle membrane found in chloroplasts that is involved in photosynthesis.

Explanation:

1. DdeI is a restriction enzyme that recognizes the sequence 5′-CTNAG-3′. It cleaves the double-stranded DNA within its recognition sequence, leaving a single-stranded overhang (sticky end) at each end. In the given wild-type beta-globin sequence (5' CTG ACT CCT GAG 3'), there is only one recognition sequence of DdeI. It is CTGA CTC, which is present between the seventh and eighth base pairs. The recognition sequence has five nucleotides. DdeI will cut the DNA at this site, producing two fragments. Therefore, the Ddel digestion of the wild-type beta-globin sequence produces two fragments: 5'-CTGACTC-3' and 5'-CTGGAG-3'.

2. In the mutant beta-globin sequence (5' CTG ACT CCT GTG 3'), the recognition site for DdeI is changed by one nucleotide from 5'-CTGA CTC-3' to 5'-CTG ACC-3'. The mutated sequence does not contain a recognition sequence for DdeI, so there will be no fragments produced by digestion.

3. To calculate the number of nucleotides in each fragment, you need to count the number of base pairs in each fragment. A base pair consists of two nucleotides. For the DdeI-digested wild-type beta-globin sequence, there are two fragments. The first fragment is 8 base pairs long, and the second fragment is 1 base pair long.  So, for the digested fragment there are 19 nucleotides in one fragment and 5 in the other fragment.

5' CTG ACT CC                 T GAG 3'

3' GAC TGA GGA CT                C 5'

The mutant fragment has no restriction site so there are 12 base pair and 24 nucleotides.

4. The difference between the wild-type and mutant beta-globin sequences can be recognized by the number of fragments produced by DdeI digestion. The wild-type sequence produces two fragments, while the mutant sequence does not produce any fragments Each fragment migrates at a different speed, placing the fragments at different distances.

5. If someone has a heterozygous beta-globin genotype, one of the chromosomes will be wild-type, and the other will be mutant. DdeI digestion of this sample will produce three fragments: two fragments from the wild-type chromosome and no fragments from the mutant chromosome. The sizes of the fragments will be the same as those produced from the wild-type sequence.

The chiasmata formation occurs during the diplotene stage of the Prophase 1.

Chiasmata are the points where the non sister chromatids attach attaches to the homologous chromosomes. It leads to exchange of segments and creates variation. The chiasma is a structure that forms between a pair of homologous chromosomes by crossover recombination and physically links the homologous chromosomes during meiosis. The chiasmata become visible during the diplotene stage of prophase I of meiosis, but the actual "crossing-overs" of genetic material are thought to occur during the previous pachytene stage.

When two different bacterial strains are crossed, it leads to the creation of new strains of bacteria. The new strains of bacteria that are created from this cross are known as the progeny. In the given scenario, the progeny is plated on minimal media plus streptomycin, lysine and histidine and colonies are formed. This experiment is done to determine the genes that are selected for on the plate. The genotypes of the bacterial strains are strs trp lys his and strr trp- lys- his-. The plus sign represents the presence of the gene while the minus sign represents the absence of the gene. The genes that are selected for on the plate are Str, Lys, and His. This can be explained as follows: The first genotype (strs trp lys his) indicates that the strain is resistant to streptomycin but requires tryptophan, lysine, and histidine to grow. The second genotype (strr trp- lys- his-) indicates that the strain is sensitive to streptomycin and does not require tryptophan, lysine, and histidine to grow. Therefore, on minimal media plus streptomycin, lysine, and histidine, only the strains that have Str, Lys, and His genes will be able to grow, and the sensitive strain will be unable to grow. Therefore, the genes that are selected for on the plate are Str, Lys, and His.

Diploid cell is a cell that contains two haploid sets of chromosomes.

What is diploid cell?
The name for a cell that contains two haploid sets of chromosomes is Diploid cell. A diploid cell is one that has two complete sets of chromosomes, and is written as 2n, where n represents the number of chromosomes in a haploid cell. Diploid cells have twice the number of chromosomes as haploid cells (1n).  

Cells that are diploid in human cells are somatic cells. Somatic cells, or any cell that is not a sex cell, are diploid. This means that in humans, all of your cells other than your eggs or sperm contain 46 chromosomes, which is two sets of 23 chromosomes. In a diploid cell, one set of chromosomes comes from the father and the other set from the mother.
