Answer and Explanation:
The steps of the scientific method are
1) A question the investigator wants to answer.
2) Antecedents or Previous knowledge about the study object.
3) The goal, which is what the investigator wants to know.
4) The hypothesis that the investigator makes in order to predict what is going to happen.
5)The experiment is performed to answer the question.
6) Results achievement
7) Conclusions where the hypothesis is rejected or accepted.
In the case of the exposed example,
- Question: How does the amount of sunlight affect the extent of flower production?
- Previous knowledge and antecedents about solar radiation influencing different plant growth and flowering. Information about the species of interest. Other studies or investigations performed in relation to this question.
- Objective/Goal: To study the influence of sunlight in flowering
- Hypothesis: Too many hours of radiation affect flowering production
- Experiment: (Example)
Native species are going to be planted in the garden to observe their growth and flower production at different exposure levels to sunlight. Native species will be planted, as they are used to the environmental conditions and they do not need extra care, as a cultivated species would. More than one individual is needed to ensure their establishment. All the species will be watered according to each species needs and location. Plagues will be equally controlled.
- 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a sunny section that receives straight sun radiation during the whole light hours.
- 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a sunny section that receives sun radiation during half a day
- 3 native individuals of a herbaceous plant, 3 native individuals of a woody plant, and 3 native grass plants are located in a shaded section.
Plants will be grown and the flowering process will be recorded by season in relation to the number of flowers, sizes, quality, and pollinizer visitors which will reflect the amount and quality of nectar.
6 y 7. Every recorded result will be then analyzed to conclude.
Lipids/Fats have glycerol in addition to three fatty acids. The structure of the fatty acids determines whether or not the fat is considered saturated or unsaturated. Phospholipids have four major components: fatty acids, a glycerol component, and both a phosphate group and a polar molecule

Answer:
Uno de los progenitores es heterocigoto para color naranja (Nn) y el otro parental es homocigoto recesivo para gris (nn). Al haber una cruza entre un homocigoto recesivo y un heterocigoto, la 50% de la progenie expresa color naranja (Nn), mientras que el otro 50% expresa color gris (nn).
Explanation:
<u>Datos disponibles:</u>
- Cruce entre peces naranjas y peces grises
- 50% de la F1 son peces grises
- Naranja dominante sobre gris
Podemos nombrar el alelo dominante para color naranja <em>N</em>, y al alelo recesivo para color gris <em>n</em>.
Para que en un cruce entre dos fenotipos distintos, el 50% de la primer camada exprese uno de estos fenotipos, entonces uno de los parentales debe ser heterocigoto, mientras que el otro parental debe ser homocigoto recesivo. De esta forma 50% de la primera generación expresara uno de los fenotipos, mientras que el otro 50% expresará el otro fenotipo.
Supongamos que uno de los parentales lleva el genotipo <em>Nn</em>, y el otro parental es <em>nn</em>.
Cruce:
Parental) Nn x nn
Gametas) N n n n
Fenotipos) Naranja Gris
Cuadro de Punnett) N n
n Nn nn
n Nn nn
F1) 2/4 = 1/2 = 50% de la progenie tendrá genotipo heterocigoto, Nn
2/4 = 1/2 = 50% de la progenie tendrá genotipo homocigota recesivo,
nn
50% de la progenie será color naranja (Nn)
50% de la progenie será color gris (nn)
Answer:
Exosphere -The exosphere layer is mainly composed of extremely low densities of hydrogen, helium, and several heavier molecules including nitrogen, oxygen, and carbon dioxide closer to the exobase. The atoms and molecules are so far apart that they can travel hundreds of kilometers without colliding with one another.
Thermosphere - The aurora (Northern Lights and Southern Lights) mostly occur in the thermosphere. The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere. ... Temperatures in the upper thermosphere can range from about 500° C (932° F) to 2,000° C (3,632° F) or higher.
Mesosphere- Most meteors burn up in the mesosphere. A type of lightning called sprites sometimes appears in the mesosphere above thunderstorms. Strange, high-altitude clouds called noctilucent clouds sometimes form in this layer near the North and South Poles.
Stratosphere-The stratosphere is the second major atmospheric layer above the troposphere, extending in altitude from about 8 to 30 miles high. No weather occurs in the stratosphere. The statosphere contains over 15% of the total mass of the atmosphere, and is where the ozone layer is located.
Troposphere-The troposphere is the lowest layer of Earth's atmosphere, and is also where nearly all weather conditions take place. It contains 75% of the atmosphere's mass and 99% of the total mass of water vapour and aerosols.
i hope this helps, good luck :)
