Why the mode of pollination in maize is cross-pollination? Why it is important to cover the ear shoot with a butter paper bag before the emergence of silks? What could be the consequences if a few silks emerge before bagging?
Answer:
The correct answer is -
1. due to the fact that maize is a monoecious crop that has male and female flowers in separate parts of the same plant that distributed pollen by the wind to other female parts of another maize plant.
2. Once silks are visible, they may already be contaminated with foreign pollen, so it is vital that ears shots are bagged before the emergence of silks.
3. If silks have emerged before bagging which means they are already been contaminated with other pollen and which will affect the process of hand pollination and have other varieties than desired.
With the population moving West, the old Northwest was made up of a.New York, Indiana, and Ohio. b.Pennsylvania, New York, and Ohio. c.Cincinnati, Indiana and Virginia. d.Ohio, Indiana and Illinois.
Answer:
With the population moving West, the old Northwest was made up of
d.Ohio, Indiana and Illinois.
Explanation:
Other states that made up the old Northwest were Michigan, Wisconsin, and a portion of Minnesota. New York, Pennsylvania, Cincinnati, and Virginia were never part of the old Northwest. The old Northwest was awarded to the United States after the 1783 revolutionary war. Geographically, the old Northwest included the land between the Great Lakes, the Mississippi River, and the Ohio River.
Suppose a friend is trying to claim that it is summer when Earth is closest to the Sun and winter when Earth is farthest away. Refute this claim in at least two different ways: (1) with an argument that invokes seasonal differences between the Northern and Southern Hemispheres and (2) with an argument based on the times of year at which Earth actually is closest to and farthest from the Sun. Write out your arguments clearly
Answer:
1) This claim is inaccurate, that there's summer when Earth is closest to the sun and winter when the planet is farthest from the sun.
2) This claim is inaccurate, because Earth is closest to the Sun on January 3-4, when it's Winter in the northern hemisphere and summer in the southern hemisphere. So why it's not Summer in both hemispheres, since the planet is closest to the Sun.
Thus, summer and winter aren't caused by the varying distance between the world and therefore the sun.
Explanation:
1)
If it's so then why seasons are Opposite in two hemispheres. it's summer within the northern hemisphere when it's winter within the southern hemisphere. Alternatively, it's Winter within the northern hemisphere, while it's summer within the southern hemisphere.
If the seasons occurred because of the gap from, sun, then it should be the same season in both the hemispheres, when Earth is farthest and closest from the Sun. Why are seasons different in both hemispheres. So this claim is inaccurate.
2)
Earth is farthest from the Sun on the Fourth of July, which is really summer in the northern hemisphere and winter in the southern hemisphere. So why is it not winter in both the hemispheres, since the planet is Farthest from the Sun.
Here the earth's orbit isn't an ideal circle. it's elliptical, or slightly oval-shaped.
In the Layers panel, turn on Borders and Labels and also Gallery > Volcanoes, then double-click on the Problem 7 placemark. Divergent boundaries often begin as triple junctions composed of three rift "arms" at ~120° apart (which may or may not evolve into divergent boundaries). Knowing that rifts (red lines) generally open perpendicular to the rift (or sub-parallel to the light blue transform faults), which of the statements below about this area is incorrect?
a. the NW-trending Red Sea is a linear sea that is opening in a NE-SW direction
b. the ENE-trending Gulf of Aden is a linear sea that is opening in a NNE-SSW direction
c. the volcanoes in Africa define a narrow linear rift that is opening in a NW-SE direction
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast
Answer:
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast
Explanation:
Many crust plates move over the mantle. These plates are limited by three types of ridges or borders that differ in the movement they produce.
Boundaries types: Divergent, Convergent, and Transforming.
Divergent boundary: Occurs along with an underwater mountain range, known as the mid-oceanic ridge or divergent ridge. New crust is created by the molten materials rising from the mantle. The two plates at each side of the rift separate, and the stream of hot material creates a new seabed between them. It occurs an expansion of the sea bottom, which separates the plates. The divergence direction is transversal to the rift orientation. Old plates get separated, and the new crust instantaneously gets formed. The emerging mantle occupies the space left by the separation of the two plates.
a. the NW-trending Red Sea is a linear sea that is opening in a NE-SW direction. CORRECT → The diverging direction is perpendicular to the rift orientation.
b. the ENE-trending Gulf of Aden is a linear sea that is opening in a NNE-SSW direction. CORRECT
c. the volcanoes in Africa define a narrow linear rift that is opening in a NW-SE direction. CORRECT.
d. the volcanoes in Africa define a volcanic arc related to subduction off Africa's east coast ⇒ INCORRECT. The collision between plates creates volcanic arches and continental arches. This process belongs to the convergent boundaries, in which two oceanic plates collide, or one oceanic plate crushes with a continental one.

explain in your own words the three mechanisms that cause air to be displaced into the atmosphere
Answer:
orographic, convectional and cyclonic lifting
Explanation:
orographic is when air mass is forced from lower to higher elevation. convectional lifting is warming up parcel of air at the surface of the earth by conduction. cyclonic lifting is lifting of air mass due to differences in pressure this is when cold air meets warm air.
The three mechanisms that cause air to be displaced into the atmosphere are orographic, convectional, and cyclonic lifting. This is further explained below.
What is air displacement?Generally, Air displacement is simply defined as plethysmography a well-known and scientifically confirmed method of measuring human body composition.

The half-life of Carbon-14 is 5, 730 years. you find a sample where 1.5625% of the original Carbon-14 still remains how old is that sample ?
Answer:
The sample is about 34380 years old.
Explanation:
The amount of Carbon-14 mass diminishes exponentially in time, whose model is described below:
[tex]\frac{m(t)}{m_{o}} = e^{-\frac{t}{\tau} }[/tex] (1)
[tex]\tau = \frac{t_{1/2}}{\ln 2}[/tex] (2)
Where:
[tex]m_{o}[/tex] - Initial mass, in grams.
[tex]m(t)[/tex] - Current mass, in grams.
[tex]t[/tex] - Time, in years.
[tex]\tau[/tex] - Time constant, in years.
[tex]t_{1/2}[/tex] - Half-life, in years.
If we know that [tex]\frac{m(t)}{m_{o}} = \frac{1.5625}{100}[/tex] and [tex]t_{1/2} = 5730\,yr[/tex], then the age of the sample is:
[tex]\tau = \frac{5730\,yr}{\ln 2}[/tex]
[tex]\tau = 8266.643\,yr[/tex]
[tex]t = - \tau \cdot \ln \frac{m(t)}{m_{o}}[/tex]
[tex]t = - (8266.643\,yr)\cdot \ln \frac{1.5625}{100}[/tex]
[tex]t \approx 34380.002\,yr[/tex]
The sample is about 34380 years old.

A three-story building had its lightweight roof uplifted. Hint: low-rise three-story, non-residential, roof uplifted completely, but no damage to walls. a. Damage Indicator Number:_________b. Degree of Damage:_________ c. Expected Wind Speed:_________ d. EF-scale Rating: _______
Answer:
a). 2
b). Moderate
c). 73-112 mph
d). F1
Explanation:
A Fujita scale is a scale that is used to determine the rating for the tornado intensities. It is used to measure the intensity of the tornado and provides a rating based on the damages made by the tornado on the human built structures and other vegetations.
The rating is based on the wind sped and the damages caused by the winds. When the damages caused by a tornado is surveyed, it is compared to the lists of Damage Indicators and the Degree of Damage which helps to estimate the range of the speeds of the tornado and an EF scale rating is provided accordingly.
In the context, It is given that the lightweight roof of a three storied building was uplifted. It was a non residential low rise three story building whose roof was uplifted completely but there was no damages made to the walls of the building.
So according to the EF scale, it provided a rating of :
Damage Indicator Number : 2
Degree of Damage : Moderate
Expected Wind Speed : 73-112 miles per hour
EF-scale Rating : F1

weathering and mass wasting
Answer:
Both processes occur in place.
Explanation:
Answer:
similarity
Explanation:
The physical disintegration or chemical change of rocks at or near the Earth's surface is known as weathering. The transfer or movement of rock or dirt down slope mostly by gravity is known as mass wasting. Erosion occurs when smaller rock fragments (now pebbles, sand, or soil) are pushed by natural forces. Weathering is the process of a rock changing or breaking but remaining in its original location. Erosion occurs when weathered rock fragments are transported away.
