Explanation:
1.The Moon has phases because it orbits Earth, which causes the portion we see illuminated to change. The Moon takes 27.3 days to orbit Earth, but the lunar phase cycle (from new Moon to new Moon) is 29.5 days. The Moon spends the extra 2.2 days "catching up" because Earth travels about 45 million miles around the Sun during the time the Moon completes one orbit around Earth.
2.
An eclipse is the result of the total or partial masking of a celestial body by another along an observer's line of sight. Solar eclipses result from the Moon blocking the Sun relative to the Earth; thus Earth, Moon and Sun all lie on a line. Lunar eclipses work the same way in a different order: Moon, Earth and Sun all on a line. In this case the Earth's shadow hides the Moon from view.Lunar and solar eclipses occur with about equal frequency. Lunar eclipses are more widely visible because Earth casts a much larger shadow on the Moon during a lunar eclipse than the Moon casts on Earth during a solar eclipse. As a result, you are more likely to see a lunar eclipse than a solar eclipse.
3.Why Do We have Seasons?
As the earth spins on its axis, producing night and day, it also moves about the sun in an elliptical (elongated circle) orbit that requires about 365 1/4 days to complete. The earth's spin axis is tilted with respect to its orbital plane. This is what causes the seasons. When the earth's axis points towards the sun, it is summer for that hemisphere. When the earth's axis points away, winter can be expected. Since the tilt of the axis is 23 1/2 degrees, the North Pole never points directly at the Sun, but on the summer solstice it points as close as it can, and on the winter solstice as far as it can.
Why Do the Seasons Change on Earth?
Two things cause the seasons to change. First, the Earth moves around the Sun. Second, the Earth has a tilted axis of rotation.
The Earth spins around an axis. This imaginary line extends from the South Pole to the North Pole. But the Earth’s axis is not vertical. It’s actually tilted at an angle of 23.5°. The planet is always tilted in the same direction as it orbits the Sun.
Why does a mask have to cover both your nose and mouth to be effective explain using the Respiratory tract
Your nose and your mouth are both a portal of entry into your body. If you cover one and not the other it defeats the purpose because Bacteria can still enter the system. They are both part of your respiratory system.

Two plants with green pods produce offspring with green pods.
Two plants with yellow pods produce offspring with green pods.
Two plants with green pods produce offspring with yellow pods.
Two plants with yellow pods produce offspring with yellow pods.
Answer:
c
Explanation:
got it right on edgenu1ty
The student hypothesizes that the green pod color in pea plants is dominant and the yellow pod color is recessive. An observation that would disprove this hypothesis is that two plants with yellow pods produce offspring with green pods, which is the second option.
What is the importance of dominance?The complete dominant allele will express itself in the heterozygous condition because it will suppress the recessive allele and express itself. Here, the green is dominant over the yellow, so the green can be purebred or can have a heterozygous condition, so the green pod having a heterozygous condition can produce both the green and the yellow pods. The yellow pods are recessive, so they can only produce yellow offspring, not green offspring, as they are only expressed in the purebred recessive forms.
Hence, an observation that would disprove this hypothesis is that two plants with yellow pods produce offspring with green pods, which is the second option.

Estrogen is one of the hormones produced by human females. Identify one organ that produces estrogen and state one specific function of estrogen in a human female.
Answer:
The ovaries. They produce the women's eggs.
Explanation:
Estrogen helps control the menstrual cycle and also helps childbearing.
The hormone estrogen is highly produced by ovaries, while some of the estrogen is also produced by the adrenal gland.
What do you mean by Hormone?Hormones may be defined as the chemical substances which are secreted by the endocrine glands and are transported to the target site via the bloodstream.
There are numerous functions of the hormone estrogen found in the body of a human female.
It helps in stimulating the growth of the egg follicle. It regulates the menstrual cycle. It also controls the thickness of uterine mucus secretions.
Therefore, it is well described above.

They are many-celled or _________________ ____________________________.All of the organism's life functions are carried out by cells or parts of cells.Cells develop from other living cells – not from nonliving matter.
Answer:
unicellular; multicellular
Explanation:
The smallest and the most basic unit of life is the cell. Living organisms that are made of just one cell are said to be unicellular while those that are made up of multiple cells are said to be multicellular. Many unicellular organisms are some of the smallest living organisms to exist in nature. They cannot be seen with the ordinary eyes, except with the aid of microscopes.

Los procesos de respiración aerobia celular y fotosíntesis, procesos considerados indispensables para la vida en la tierra, de los que es correcto afirmar que Son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas. La respiración celular sólo la realizan los seres eucariotas del reino de los vegetales. Ambos son realizados por los seres considerados eucariotas. Ambos son realizados por eucariotas pertenecientes al reino de los vegetales
Respuesta:
Las opciones correctas son: a) son de carácter antagónico, es decir el cloroplasto ejecuta reacciones anabólicas y la mitocondria catabólicas; y d) ambos son realizados por eucariotas pertenecientes al reino de los vegetales.
Explicación:
La fotosíntesis y la respiración celular son procesos de carácter antagónico porque la fotosíntesis es anabólica y la respiración celular es catabólica. La fotosíntesis consiste en la producción de moléculas complejas a partir de moléculas simples (proceso anabólico), mientras que en la respiración celular se degradan moléculas complejas y se las convierte en moléculas más simples (proceso catabólico).
Ambos procesos son realizados por los eucariotas del reino de los vegetales, pero los eucariotas del reino animal sólo realizan respiración celular, ya que no tienen cloroplastos. Esta diferencia tan importante existe porque los animales pueden moverse para conseguir comida (heterótrofos), mientras que los vegetales necesitan producir sus propios nutrientes haciendo uso de la fotosíntesis (autótrofos). Más allá de esta diversidad, todos los eucariotas realizan respiración celular para producir energía en forma de ATP.
