prairie dogs north america Indirect relationship (between keystone species and other organisms): Preservation Status:
Answer:
Indirect relationship.
Explanation:
There is indirect relationship between keystone species and other organisms because both species affect each other not directly but indirectly. The keystone predation was the most common of the indirect effects on other abundance of other species. The predation of keystone species decrease the population of keystone species which indirectly increases the population of competitors in that environment.

Which is the path of sperm from the testes to the urethra?
Answer:
Sperm then travels through the deferent duct through up the spermatic cord into the pelvic cavity, over the ureter to the prostate behind the bladder. Here, the vas deferens joins with the seminal vesicle to form the ejaculatory duct, which passes through the prostate and empties into the urethra
Answer:
epididymis, vas deferens, seminal vesicles , prostate gland, urethra

What is the name of one convection cell that forms because of the Coriolis effect? How does the air move in that convection cell?
Answer:
Hadley CellsWarming air causes it to ascend. The cool air will sink. The action eventually results in a convection cell, with air rising, traveling to the side, dropping, and returning. This heat-driven air movement circulates heat throughout the atmosphere.OAmalOHopeO
de que sustancia esta lleno el cromosoma
Answer:
Los cromosomas están compuestos por dos cadenas largas de polinucleótidos asociados a proteínas histonas
Explanation:
Un cromosoma es una molécula lineal de ácido desoxirribonucleico (ADN) la cual está compuesta por dos cadenas de nucleótidos dispuestas en forma de doble-hélice. En el ADN, cada nucleótido está formado por una azúcar desoxirribosa, un grupo fosfato y un tipo de base nitrogenada (los cuatro tipos de bases nitrogenadas que forma nucleótidos en la molécula de ADN son Timina, Guanina, Citocina y Adenina). La molécula larga de ADN en doble hélice se encuentra asociada a proteínas histonas para formar las fibras de cromatina. Aproximadamente 150 pares de bases de la molécula del ADN se encuentran enrolladas con las histonas H2A, H2B, H3 y H4 (dos subunidades de cada una) para formar un nucleosoma, la unidad básica de la cromatina. Finalmente, es importante indicar que la molécula de ADN contiene regiones no codificantes y regiones codificantes, es decir, fragmentos de ADN los cuales son utilizados como templados para producir moléculas de ARN mediante un mecanismo conocido como transcripción. Los ARN mensajeros (ARNm) son un tipo especial de ARN sintetizados a partir de fragmentos codificantes de ADN conocidos como 'genes'. Posteriormente al proceso de transcripción, estos ARN mensajeros sirven a su vez como templados para la síntesis de proteínas en los ribosomas, mediante un mecanismo conocido como 'traducción'.
What is the biology behind the improvement of strength in the human body? describe
Answer:
Due to its function to fight against disease.
Explanation:
Improvement of strength in the human body is very important because strong body helps in fighting against diseases. Strong body helps in doing physical activities and also helps in protecting itself from every type of harm. Weak human body can't fight against diseases due to weak immune system so we can conclude that improvement in human body is necessary for survival, development and health of human.
Based on what you know about the relationship between the burning of fossil fuels (coal, oil, gasoline) and CO2, how could this also contribute to the cyclic nature of CO2 concentrations throughout the year?
Explanation:
levels of the carbon dioxide in the atmosphere rise and fall each year as plants through photosynthesis and respiration take up the gad in the spring and summer and release it in fall and winter. Now the range of that cycle is expanding as mire carbon dioxide is emitted from burning fossil fuels and other human activities

what scientific term is used to describe all the genes of one organism?
Answer:
The scientific term used to describe all of the genes in an organsim is the genome.
Genome term is used to describe all the genes of one organism, it forms the genotype of an organism.
What is a genome?the entirety of an organism's genetic makeup, or DNA. Nearly every cell in a person's body has a complete copy of its genome. Everything a person needs to grow and develop is encoded in their genome.
Each and every one of the body's cells, such as the skin cell or the liver cell, carries the following set of instructions: DNA makes up the instructions in our genome.
The genome's main job is to preserve, express, and store the genetic material that gives rise to a cell's structural and functional machinery. The genome is a significant part of the cell's structural makeup, nevertheless. Hence, the Genome term is used to describe all the genes of one organism.
