What are bóng đá hôm nay trực tiếp short answer questions for review for bóng đá hôm nay trực tiếp 1st mid-semester test of 12th-grade Biology in Vietnam?

Below are some short answer questions for review for bóng đá hôm nay trực tiếp 1st mid-semester test of 12th-grade Biology in Vietnam:

Question 1:A gene segment has bóng đá hôm nay trực tiếp nucleotide sequence on one polynucleotide chain as follows: 3’ – ATG - TAC - CGT - AGG - XXX - 5’ Calculate bóng đá hôm nay trực tiếp number of hydrogen bonds in bóng đá hôm nay trực tiếp gene segment above. Question 2:With 3 types of ribonucleotides A, U, and G, how many codons can be formed to code for amino acids in a polypeptide chain? Question 3:A gene mutation occurred in bóng đá hôm nay trực tiếp structure of bóng đá hôm nay trực tiếp lac operon causing bóng đá hôm nay trực tiếp structural genes not to be expressed even when lactose is present or absent in bóng đá hôm nay trực tiếp environment. In which region of bóng đá hôm nay trực tiếp lac operon did this gene mutation occur? Question 4:An organism has bóng đá hôm nay trực tiếp genotype AaBbDd. If during meiosis, 10% of bóng đá hôm nay trực tiếp cells experience nondisjunction of bóng đá hôm nay trực tiếp chromosome pair carrying bóng đá hôm nay trực tiếp Bb genes in meiosis I, with meiosis II occurring normally, and other chromosome pairs segregating normally, what is bóng đá hôm nay trực tiếp ratio of mutant gametes carrying bóng đá hôm nay trực tiếp ABbD genotype? Question 5:According to Mendel's law of independent assortment, theoretically how many percent of offspring individuals will display a dominant phenotype in 3 out of 4 traits when an AaBbCcDd plant performs self-pollination? Question 6:bóng đá hôm nay trực tiếp fruit weight trait of a plant species shows additive gene interaction, with gene pairs sorting independently. Given a plant heterozygous for all gene pairs self-pollinates, bóng đá hôm nay trực tiếp F1 generation displays 9 phenotypes for fruit weight trait, with bóng đá hôm nay trực tiếp heaviest fruit weighing 150 g and bóng đá hôm nay trực tiếp lightest 70 g. In bóng đá hôm nay trực tiếp F1 generation, how many genotypes determine bóng đá hôm nay trực tiếp phenotype of fruit weighing 100 g? Question 7:2 DNA molecules are replicating 3 times. From bóng đá hôm nay trực tiếp produced DNA molecules, select randomly 3 DNA molecules for 5 more replications. What is bóng đá hôm nay trực tiếp total number of resulting DNA molecules? Question 8:On an mRNA molecule, bóng đá hôm nay trực tiếp nucleotide sequence is as follows: 5’ XXX AAU AUG GGG GGG UUU UUX UUA AAA UGA 3’. If bóng đá hôm nay trực tiếp mRNA molecule undergoes translation, how many codons and anticodons brought by tRNA properly match with ribosomes, respectively? Question 9:In bóng đá hôm nay trực tiếp bacteriaE. coli, assume there are 4 strains carrying mutations related to bóng đá hôm nay trực tiếp lac operon. These mutations are described in bóng đá hôm nay trực tiếp following table: In bóng đá hôm nay trực tiếp table, plus signs (+) indicate functional genes/components, and minus signs (-) indicate non-functional genes/components due to mutation. Theoretically, which strains will transcribe structural genes when lactose is present in bóng đá hôm nay trực tiếp environment? Question 10:An openly pollinated plant species has a diploid chromosome set of 2n = 6. Considering 3 gene pairs A, a; B, b; D, D located on 3 chromosome pairs, each gene determines a trait, and all dominant alleles are fully dominant. Assume bóng đá hôm nay trực tiếp species has arisen trisomies corresponding to chromosome pairs due to mutation, and these trisomies are viable and capable of reproduction. Theoretically, how many maximum genotypes for bóng đá hôm nay trực tiếp genes under consideration can these species have?

Who has bóng đá hôm nay trực tiếp powerto issue bóng đá hôm nay trực tiếp internal regulations ofsecondary schoolsin Vietnam?

According to point d, clause 1, Article 11 of bóng đá hôm nay trực tiếp charter of lower secondary schools, upper secondary schools, and multi-level schools issued together withCircular 32/2020/TT-BGDDT, bóng đá hôm nay trực tiếp regulations state as follows:

School principal and deputyprincipals

1. School principal

...

d) Duties and rights of principal:

- Build and organize bóng đá hôm nay trực tiếp school’s apparatus according to regulations in Article 9 of this charter; appoint department/unit heads and deputy heads; and establish bóng đá hôm nay trực tiếp school council as per regulations in Points dd and e Clause 1 Article 10 of this charter;

- Formulate bóng đá hôm nay trực tiếp school’s development planning, objectives, vision and strategies; bóng đá hôm nay trực tiếp school’s organizational and operational regulations; and bóng đá hôm nay trực tiếp school’s annual education plans, which shall be proposed to bóng đá hôm nay trực tiếp school council for approval and implementation;

- Adopt bóng đá hôm nay trực tiếp school council’s decisions or conclusions concerning bóng đá hôm nay trực tiếp matters mentioned in Point c Clause 1 Article 10 of this Decree. In case bóng đá hôm nay trực tiếp principal does not agree with a decision from bóng đá hôm nay trực tiếp school council, obtain bóng đá hôm nay trực tiếp opinion of bóng đá hôm nay trực tiếp supervisory education authority. While waiting for said opinion, bóng đá hôm nay trực tiếp principal must abide by bóng đá hôm nay trực tiếp parts of bóng đá hôm nay trực tiếp school council’s decision that are not against existing regulations of law and this charter;

- Submit reports on and assessment of implementation of bóng đá hôm nay trực tiếp school’s education plan and decisions issued by bóng đá hôm nay trực tiếp school council to bóng đá hôm nay trực tiếp school council and competent authorities;

- Recruit and manage teachers and staff; sign labor contracts with teachers and staff, and receive and relocate teachers and staff; manage academic matters; assign tasks to teachers and staff, inspect and evaluate teachers and staff; and reward and discipline teachers and staff as prescribed by law;

...

Thus, bóng đá hôm nay trực tiếp Principal has bóng đá hôm nay trực tiếp responsibility to formulate bóng đá hôm nay trực tiếp school’s development planning, objectives, vision, and strategies; bóng đá hôm nay trực tiếp school’s organizational and operational regulations. Thus, bóng đá hôm nay trực tiếp Principal has bóng đá hôm nay trực tiếp power to issue bóng đá hôm nay trực tiếp internal regulations of secondary schools in Vietnam.
