Answer:
Because 2 forces are stopping the crate, friction and gravity. While only one force is trying to move it forward.
Beta vulgaris,
which commonly known as Sugar beets; it is a bulky taproot that cultivates
underground. It is best developed in soil that is rich with nutrients and profound
enough for numerous inches of agriculture. The climate of the place should have
long duration of adequate intensity of sunlight, which corresponds to the
weather in the Red River Valley of the North.
Answer:
A) The striations are due to the orderly arrangement of actin and myosin
Explanation:
Smooth muscles are non-striated involuntary muscles which are found in the walls of stomach, urinary bladder, blood vessels...Smooth muscle tissue is composed of spindle-shaped muscle cells with single central nucleus. Like the other two type of muscles (cardiac and skeletal), smooth muscles also have four main functions:
- Contractility-ability to contract. In the case of skeletal muscles it is voluntary, while in cardiac and smooth muscles it is unconscious.
- Excitability-ability to change membrane potential usually by the influence of nervous impulse.
- Extensibility-the capacity to lengthen
- Elasticity-ability to change its length and then return to previous.
Answer:
By researching, I would think that the answer is D. Ice crystals melt as they fall through a warm layer of air and then refreeze into small ice pellets as they pass through a colder layer of air.
Explanation:
<em>During precipitation formation, if temperatures are at or below freezing, 0°C (32°F), at cloud level, water in the air freezes into ice crystals, and the crystals stick together to make snow. The snow starts to fall, and if the air column is freezing cold all the way down from the clouds to the ground, the precipitation stays frozen. It simply falls as snow.</em>
<em />
<em>Sometimes, however, a temperature inversion occurs. Normally, the temperature decreases with increasing altitude. A temperature inversion is when a layer of warm air intrudes between the ground and the clouds.</em>
<em />
<em>Under these conditions, when the falling snow reaches the layer of warm air, it melts. Then it hits the layer of cold air just above Earth’s surface and refreezes. This all happens very fast, and the result is tiny ice pellets called sleet.</em>
Answer:
d. Autoradiographies
Explanation:
Based on the information provided within the question it can be said that the technique that is mainly used for this are Autoradiographies. This is a technique that is mostly used for X- ray film to visualize molecules or fragments of molecules that have been radioactively but are also used for analyzing the length and number of DNA fragments using a special method called gel electrophoresis which is then used to compare the various DNA samples.
