Francis was recording plant heights for an experiment. Each time that she took a measurement, she wrote it down. Then, she measured the plant again and compared the new measurement to the one that she had recorded in her notebook. What was she most likely trying to do
revise her hypothesis
check her memory
make the data more valid
form a conclusion
revise her hypothesis I guess because
she recorded the experiment again and again and then wrote it so she could get more knowledge about the experiment

How does connective tissue provide support the body?
Answer:
Connective tissues perform many functions in the body, but most importantly, they support and connect other tissues; from the connective tissue sheath that surrounds muscle cells, to the tendons that attach muscles to bones, and to the skeleton that supports the positions of the body.
Explanation:
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

B. 25%
Answer:
I believe it is B
Explanation:
hope this helps
Answer:
B. 25%
Explanation:
There is a 50-75% or about half chance that the babies bred by a Skinny Pig and a haired Skinny pig gene carrier, will have hairless Skinny pig babies. The rest of the babies will just be skinny pig gene carriers. There is only a 25% chance that 1 or so hairless skinny babies will be born in these litters.

Which hormone is involved in female puberty, pregnancy, and menopause?
What map unit (Centimorgan) is adopted in
the construction of genetic maps?
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.
