However it shouldn't be taken too seriously. Conversation on the dinner table can be fun while enjoying a meal with many other people. However conversation is done before taking a bite as talking with your mouth full is disrespectful to others and shows bad manners.
Explanation:
A typical eukaryotic nucleus has to exchange a great deal of protein and nucleic acid material with the surrounding cytosol of the cell. Which choice correctly describes a feature of most nuclei that helps promote this exchange
Answer: A typical Eukaryote has an organized nucleus as well as an organized cell organelles.
The nucleus is enclosed in a nuclear envelope and the whole cell organelles are further enclosed in a plasma membrane (cell membrane).
From the question,the choice that correctly describe the feature of most nuclei that helps to promote the exchange of protein and other nucleic acids between the nucleus and the surrounding environment is the presence of nuclear pores which allows for selective movement of materials/items in and out of the nuclear space in a regulated manner.

Exotoxins are Question 8 options: only released after a cell is damaged or lysed. proteins. lipopolysaccharides. secretions that always target nervous tissue. antiphagocytic factors.
Answer:
The correct answer is proteins.
Explanation:
The exotoxins are proteinaceous in nature, they are the toxins, which are discharged from a living bacterium and are also discharged at the time of bacterial lysis. The exotoxins harm humans, however, not all exotoxins generated harm human beings.
Some are even created to perform an essential function in bacteria physiology like regulating functions of the cell, resisting bacteriophages, or quorum sensing. The three prime kinds of exotoxins are type I exotoxins or superantigens, type II toxins or exotoxins that damage host cell membranes, and type III toxins or A-B toxins that interfere with the function of the host cell.

Which of these would be considered a transgenic organism? a human treated with insulin produced by E. coli bacteria a rat with rabbit hemoglobin genes a bacterium that has been treated with a compound that affects the expression of many of its genes a fern grown in cell culture from a single fern root cell a houseplant propagated from the cuttings of another houseplant
Answer:
a rat with rabbit hemoglobin genes
Explanation:
When the genome of an organism is modified in the field of genetic engineering,by transplanting the gene(DNA) from one organisms to another,(by vectors) or alteration of the gene components,the resulting organism produced or formed is called Transgenic organism.
This process of genetic engineering makes use of recombination of genes to alter the genome of the transgenic organism.
Thus by transferring to rat ( the DNA for Hb) as the rabbit Hb,the gene( or genome) for producing Hb in tats has been modified by that of rabbit.Hence Rat is said to transgenic.
Besides animals crop plants are also genetically modified.Thus the genome of some crops are altered to resist herbicides and pesticides. Some species of rice (golden rice)have been modified to add certain vitamins to improve the nutritional values.
Genetically modified bananas as edible vaccines are another example
In order for translation to occur: Please choose the correct answer from the following choices, and then select the submit answer button. transcription must be occurring simultaneously. there must be large numbers of free amino acids present in the cytoplasm. the DNA must produce large numbers of free amino acids. replication must be occurring simultaneously. the nuclear membrane must first dissolve
Answer:
there must be large numbers of free amino acids present in the cytoplasm
Explanation:
In order for translation to occur, there must be a large number of free amino acids in the cytoplasm.
These free amino acids are usually carried by the transfer RNA which also carries the corresponding mRNA codon.
During translation, as the codons in the mRNA match their complements in the tRNA, the amino acid being carried by the tRNA is released and a peptide bond is formed between subsequent amino acids until the required polypeptide bond is formed.
Translation and transcription only occur simultaneously in prokaryotic cells where there is no barrier between the cell's genetic materials and the cytoplasm, unlike in eukaryotic cells where the genetic materials are housed in the membrane-bound nucleus.

Some individuals can be heterozygous for a particular mutation.This means that one of their chromosomes is normal and the other is mutated in some way. Approximately ___ of the gametes produced by an individual heterozygous for a deletion will be non viable.
Answer:
1/2 (50%)
Explanation:
During meiosis, homologous pairs of chromosomes are separated in order to form haploid cells, and this separation or assortment is known to be a random process. In consequence, the chromosome carrying the mutation will have a 1/2 (50%) chance of being inherited in the gamete that, after fertilization, produces a non-viable organism. In consequence, the non-mutated chromosome also will have a 1/2 chance of occurring in the offspring
Which explanation provides support for continental drift theory? O Dinosaurs lived on many continents. Coal fields match up across continents. Tropical plant fossils were found in warm areas. Similar rock types are found across continents.
Answer:
Similar rock types are found across continents
Explanation:
Can I have brainliest?
Similar composition of rocks are present across continents that support the theory of continental drift.
Similar rock types are found across continents is the evidence that support the continental drift theory because at the boundaries of two continent there must be similar type of rock present. Scientist Alfred Wegener presented Continental drift theory in the early 20th century.
Wegener noticed similarities between two continents when he pieced together maps of Africa and South America. He noticed that mountain ranges present on both continents line up to each other which means they are made of similar type of rock so we can conclude that similar types of rock are present across continents.

The correct answer is "reticular formation".
Explanation:
The missing options of this question are:
A) medial lemniscus
B) pyramidal system
C) anterolateral system
D) reticular formation
E) extrapyramidal system
The correct answer is option D) "reticular formation".
The term "reticular formation" was coined to mention a set of interconnected nuclei located along the brainstem, including the cerebrum, diencephalon, and the brainstem itself. Nowadays this term is considered inaccurate and misleading, since it was never well defined and some authors may include some structures that other author do not consider as part of the "reticular formation".
A forensic scientist is trying to find out the number of adenine bases in the DNA sample that he obtained from a crime scene. What can he assume about the number of adenine? The number of adenine bases will be equal to the number of guanine bases. The number of adenine bases will be equal to the total of all the other bases. The number of adenine bases will be equal to the number of thymine bases. The number of adenine bases will be half of the number of cytosine bases.
Answer:
The correct option is;
The number of adenine bases will be equal to the number of thymine bases
Explanation:
The four chemical bases that make up the DNA code are adenine (A), guanine (G), thymine (T), and cytosine (C) which are arranged based on a specif organism such that they represent the information regarding the building of the organism
The chemical bases of the DNA are found in pairs consisting of two chemical bases which are then known as base pairs. The possible base pairs are;
Adenine (A) pairing with thymine (T)
Cytosine (C) pairing with Guanine (G)
Therefore, the forensic scientist should expect to find that the number of adenine bases will be equal to the number of thymine bases.
Since the scientist was trying to find out the number of adenine bases in the DNA sample, assumption that the number of adenine would be equal to the number thymine would help.
According to the base-pairing rule of Chargaff, adenine always pairs with thymine while guanine always pairs with cytosine.
Going by this rule, we can say that the number of adenine must be equal to the number of thymine while the number of guanine must be equal to the number of cytosine in any DNA.

Calcium is an important element in the body with majority of its percentage located in the bones. Its ions perform different functions in the body which includes muscle contraction, hormones secretion and including all other functions.
Calcium ion is absorbed in the intestines and then reabsorbed in the kidney. Much percentage of calcium ions is reabsorbed by passive mechanisms in the proximal convoluted tubule of the kidney tubule as compared to all other parts of the kidney tubule.
Gastrin, histamine, endorphins, serotonin, cholecystokinin, and somatostatin are hormones or paracrines that are released directly into the lamina propria. Which of the following cell types synthesize and secrete these products?
a) parietal cells
b) enteroendocrine cells
c) mucous neck cells
d) zymogenic cells
Answer:
The correct answer is option b, that is, enteroendocrine cells.
Explanation:
The specialized cells of the pancreas and the gastrointestinal tract exhibiting endocrine function are termed as enteroendocrine cells. These cells generate gastrointestinal peptides or hormones in response to a distinct kind of stimuli and discharge them into the bloodstream for the systemic effect. These are the most varied endocrine cells found within the body.
The intestinal enteroendocrine cells produce somatostatin, cholecystokinin, motilin, enteroglucagon, and neurotensin hormones. The G cells present within the intestine produce gastrin. In the gastric glands, the gastric enteroendocrine cells are present, which produce histamine, and others like cholecystokinin, alpha and gamma-endorphin, somatostatin, and others.
In the islets of Langerhans, the pancreatic enteroendocrine cells are present, which produce hormones like ghrelin, amylin, somatostatin, and pancreatic polypeptide.
