Ayuda con la tarea de biología
La parte más complicada de aprender biología es cómo hacer que los estudiantes comprendan el mundo microscópico de la biología, cómo entrar en las células y explorar genes y moléculas. Sin embargo, con el desarrollo de la tecnología de la información, la ayuda con la tarea de biología puede desempeñar un papel importante cuando ni las palabras ni las imágenes pueden explicar completamente los puntos de biología.
QuestionAI es un software de aprendizaje de biología en línea que le ayuda a aprender y dominar el conocimiento de la biología, incluida una variedad de experimentos y ejercicios correspondientes, que es fundamentalmente diferente del ayudante común de preguntas de biología. Aquí, puede simular experimentos para reproducir los escenarios experimentales, de superficial a profundo, capa por capa, para aprender y comprender los puntos de conocimiento.
- Section 2: Movement of Substances 6. Molecules naturally move from areas of __ concentration to __ concentration in a process called __ 7. Water moves across membranes through a specific type of diffusion known as __ 8. A process that allows large or charged molecules to pass through the membrane with the help of proteins , but without energy use is called __ 9. When a cell expends energy to move substances against their concentration gradient, it is performing __ 10. If a cell is placed in a solution that causes it to swell, the solution is __ , whereas if the cell shrinks, the solution is __
- 1. During the cell cycle , proteins called cyclins bind to enzymes that send signals for the cell to progress through stages of cell replication. At the end of this cycle, the cyclins degrade to prevent further signaling for the cell to divide . Uncontrolled production of cyclins will most likely result in - A the formation of tumors B the immediate death of the cell C the transfer of cyclins to other cells D the formation of haploid cells
- 4x Aresearch program is launched to produce genetically modified varieties of a food crop. The aim of the program is to create varieties with fruit that ripen quicker. Which idea can be used BEST in an argument against such research? A New unknown proteins may be produced by the modified plants. B The fruit from the modified crop might have a different taste. C The modified crop will reduce the sales of chemical fertilizers. D Smilar research programs in the past have led to harmful effects.
- 4x Although genetically modified crops have been on the scene for many years.there still remains a large gap between the public sector and biotechnology research and development firms.Most recently, the development of golden rice has been stalled. Golden rice has been genetically modified to increase the production of beta carotene. Beta carotene is a dietary essential that is lacking in the diets of people who live in poverty. Found in vitamin A. this deficiency has lead to partial or total blindness in over half a million children world wide. Although medical and social research suggest the need for golden rice, certain beliefs hinder its production and distribution, as well as the continued research and development of genetically modified crops. They include all but A A the unknown impacts on ecosystems B genetic transfer to unintended crops C improvements in both plant and animal food resources. D D genetically modified foods are detrimental human health.
- GENE TICS AND HEREDITY we 1. The study of genes and how traits are passed down from one generation to the next is called . __ a) Biology [btue] b) Genetics [gold] c) Heredity [purple] d) Test cross (light plak] 1 o)DNA 2. The process of passing traits from parents to offspring is called __ a) Heredity forange] b) Genotype c) Reproduction d) Genetics tred [yellow] then circle the correct response. Use the color that corresponds with after you have answered I all the questions. You may use any color of are not assigned a color. 16. Altemate versions or forms of a gene that determine distinct traits that can be passed on from parents to offspring. For example: B. black or b-blue 1 a) Traits [orange] 1 b) Alleles [red] (dark green I d) Chromosomes [yellow] 17. This term refers to two identical alleles. Also called purebred Example: RR or rt. [light green] I a)Homozygous [blue] 1 b) Dominant flight green 1 c) Genotype [purple] I d) Heterozygous [red] 18. An organism's observable characteristics or I traits are known a its __ [light pink] Ia)Phenotype [purple] 1 b) Dominance [dark green] c)Genotype dark gree [lavender] I d) Alleles [light pink] [orange] 19. The genetic makeup of an organism, represented by pairs of letters such as BB, Ss. or aa, is known as its: I a)Phenotype 1 b) Dominance [orange] [light green] i c)Genotype [yellow] I d) Alleles blue dark gree 5. Thread-like structures containing tightly colled DNA found inside the nucleus of a cell are called __ a) Chromosomes 110. A term that is used to describe an allele that is I expressed in the phenotype when at least one copy is present. b) Proteins [light pink] | a) Recessive c) Genes green]i b) Incomplete dominance [lavender) d) RNA [purple] 1 c) Heterozygous [red] [blue] I d)Dominant (light pin) flight gree 3. The nucleic acid that contains the genetic information for heredity in most organisms is known as __ a) Chromosome b) Alleles c) Gene d) DNA [blue] 4 __ are segments of DNA that contain codes for the production of proteins. They are I the basic unit of inheritance. a) Chromosomes b) Genes [red] c) Alleles d) Lod [orange] [yellow]
