Severe flooding in an area caused a population of minnows to become split into two separate ponds. Prior to the separation, the male minnows all had a moderate number of spots.
Following the separation, the first pond was filled with larger fish that fed on minnows, so male minnows with fewer spots were better able to avoid detection by predators. The minnows in the second pond, however, had very few predators, and female minnows in this pond preferred to mate with males that had the most spots.
After many generations, the two minnow populations evolved into different species and could no longer interbreed.
Fish Species Average # of Spots
Original Species four to six
New Species 1 zero to two
New Species 2 eight to ten
Which of the following best describes why the two minnow populations evolved into separate species?
A.
Natural selection acted upon the traits of the minnows in the first pond only, causing these fish to evolve into a new species with new adaptations.
B.
Natural selection acted upon the traits of the minnows in the second pond only, causing these fish to evolve into a new species with new adaptations.
C.
The same selective pressures were acting upon both populations, leading to a decrease in genetic variation and the formation of two new species.
D.
Different selective pressures were acting upon the two populations, leading to an increase in genetic variation and the formation of two new species.

During cell polarization, what are the two resultant edges called?
Answer:
The leading and trailing edge
Explanation:
Cutting the front edge of each wave's half cycle using leading edge dimming. Trailing edge dimming, on the other hand, eliminates the second half of each wave's half cycle.
~
During cell polarization, the two resultant edges are called the leading edge and the trailing edge.
What do you mean by Cell polarization?Cell polarization may be defined as a phenomenon by which cytoskeletal arrangement, extra- and intracellular signals, and organelle and membrane reorganization occur due to maintaining the cell shape.
Leading-edge works on the front edge and separates the half-wave cycle, while the trailing edge works on the back edge and cuts the second half of the wave.
Therefore, during cell polarization, the two resultant edges are called the leading edge and the trailing edge.

What is the only form of nitrogen that plants can absorb?.
The only nitrogen plants can absorb is nitrate. Nitrogen assimilation in plants. Plants absorb nitrogen from the soil in the form of nitrate (NO3−) and ammonium (NH4+). In aerobic soils where nitrification can occur, nitrate is usually the predominant form of available nitrogen that is absorbed.

Which of the following types of carbon fixation is least common for plants in arid locations? a. c3 b. c4 c. cam d. none of the above please select the best answer from the choices provided a b c d
Answer:
The answer will be:
A. C3
The processes of converting inorganic substances into organic substances are called carbon fixation. It can include C3 photosynthesis, C4 photosynthesis and CAM. C3 is least common in arid areas.
What is carbon fixation?Carbon fixation is the process, when photosynthetic bacteria form organic carbon from inorganic ones.
Carbon fixation can have three processes as follows:
C3: it is light independent process occurs in stroma it occurs in all plants but is less common in arid location plants.C4: it is found in plants of tropical areas.CAM: it occurs in plants present in arid areas.Thus, option a is correct.

The respiratory system is lined with a tissue layer known as the mucous membrane. We discussed how this layer helps to alter the incoming air in three important, beneficial ways. Explain the three ways the mucous membranes alter the incoming air and the benefit of each of these alterations
Warming, add moisture and trap depris are the three ways the mucous membranes alter the incoming air.
Role of mucous in breathingNasal mucous membranes are lined with small blood vessels that help to warm as well as humidify the air you breathe. They are also lined with cilia which is a tiny hair-like structures that help to trap the debris that you breathe in during inhalation.
So we can conclude that warming, add moisture and trap depris are the three ways the mucous membranes alter the incoming air.

Neurons in the visual cortex respond to which type of stimulus?
Answer:
luminance
Neurons in the visual cortex respond essentially to the variations in luminance occurring within their receptive fields, where each neuron fires maximally by acting as a filter for stimulus features such as orientation, motion, direction and velocity, with an appropriate combination of these properties
Explanation:
Neurons in the visual cortex respond to luminance stimulus. They respond selectively to various stimuli depending on the features.
What do you mean by Neurons?Neurons may be defined as the cells which are responsible for receiving sensory input from the external world and processed in the brain.
Neurons in the primary visual cortex respond to local edges or contours at a particular orientation, motion, direction, and stereoscopic depth.
Therefore, neurons in the visual cortex respond to luminance stimulus.
