Which best describes what is occurring in this population of squirrels? Number of Squirrels Entering and Leaving a Population after 1 Year Cause of change Number of squirrels Died from predation 2 Born 4 Immigration 10 Left to find food 3 Died from disease 8 Left to find a mate 3
Answer:
Explanation:
The population of squirrel is decreasing and this can be traced to the environment not being favorable for their growth and development.
Looking at the data generated,
Died from predation =2
Born=4
Immigration=10
Left to find food =3
Died from disease=8
Left to find mate=3
If all the squirrel did not abandon their habitat and they all live there a total of 2+4+10+3+8+3= 30 squirrel would have been present, but given that only 4 were born and that others left for another place the population is reduced to 4 and 26 squirrel gone this has lead to a reduced population.
Answer:
A
Explanation:
Population growth is decreasing.

Which of the following are necessary for a seed to germinate?
Answer:
The question lacks options, the options are:
A. moisture content of seed must be at least 9%
B. Moisture content of the seed must be less than 9%
C. certain enzymes in the seed are activated
D. temperature must be above 80 degrees
E. temperature must be below 80 degrees
The answer is A
Explanation:
Germination is practically the very first step of every seed-producing plant. It is the process whereby seeds sprout or begin to grow. Germination requires certain conditions to be met in order to occur. This conditions include presence of moisture in the soil etc.
The water is absorbed by the seed helps to soften the seed coat, which protects the seed from damage. The seed coat ruptures, causing the emergence of growth structures from the seed. In general, seeds need water to activate their dormant physiology. Hence, the moisture content of the seed must not be lower than 9%.

A student working on their science experiment places four potato squares into solutions of Iodine and measures how far the Iodine diffuses into the potato. The measurements are: 2.1 mm, 1.8 mm, 2.3 mm, and 2.2 mm. What is the average diffusion distance?
Answer:
The average diffusion distance is 2.1 mm
Explanation:
Given
Diffusion distance of the four potato squares are;
[tex]Potato 1: 2.1 mm\\Potato 2: 1.8 mm\\Potato 3: 2.3 mm\\Potato 4: 2.2 mm[/tex]
Required
Average Diffusion Distance
To calculate the average diffusion distance; we simply calculate the mean of the student recordings
Mean is calculated as thus;
[tex]Mean = \frac{\sum x}{n}[/tex]
Where x is the individual distance of the potato squares
[tex]\sum x = 2.1 mm + 1.8 mm + 2.3 mm + 2,2 mm[/tex]
[tex]\sum x = 8.4mm[/tex]
n is the number of potato squares
n = 4
[tex]Mean = \frac{\sum x}{n}[/tex]
[tex]Mean = \frac{8.4 mm}{4}[/tex]
[tex]Mean = 2.1 mm[/tex]
Hence, the average diffusion distance is 2.1mm
In a eukaryotic cell, what separates DNA from the protein translation machinery in the cytoplasm?
Answer:
Explanation:
In eukaryotic cells, the membrane that surrounds the nucleus — commonly called the nuclear envelope — partitions this DNA from the cell's protein synthesis machinery, which is located in the cytoplasm.
Plant cells have cell walls, but animal cells don’t. Why might that be?
Answer:
plant cell need cell wall whereas animal cell do not because the plants need rigid structure so that they can grow up and out. Cells have cell membrane. The membranes can flex. Animal cells can have varios shapes, but plant cells only have the shapes of plant cell wall.
Explanation:
The data in the graph are the result of a paramecium being placed in a hypertonic salt solution. A graph entitled Paramecium Contractile Vacuole Contractions has salt concentration on the horizontal axis and contractions per minute on the vertical axis. A very low salt concentration has 30 contractions per minute, low: 22, medium: 15, high: 8, very-high: 2. What change would most improve the usefulness of the graph? Replace the concentration descriptions with actual values. Plot contractions per second instead of contractions per minute. Remove the plotted points and just keep the line. Remove the name of the organism from the title.
Answer:
Replace the concentration descriptions with actual values
Explanation:
For results of this nature to mean much, they need to be able to be reproduced by a different experimenter. In order to be able to do that, the experimenter must be able to reproduce the salt concentrations. The graph would be more useful if it had the actual concentration values.
Answer:
Replace the concentration descriptions with actual values

Does Astigmatism cause blindness? Can Astigmatism be cured?
Answer:
Astigmatism is a problem of how the eye focuses light typically caused by a defect in the lens, resulting in distorted images. Astigmatism is not an eye disease or health problem. While it can cause blurred vision, eye strain, and headaches, particularly after prolonged reading, it does not cause blindness.
Astigmatism can be corrected with glasses, contact lenses, or refractive surgery (i.e. laser eye surgery), although treatment may not be necessary if the symptoms are mild. Glasses and contact lenses both compensate for the irregular shape of the cornea and help to focus light properly into the back of the eye

Q-Cars are usually made of metal. In an accident they bent but donot break.Why is this useful ?
Answer:
If vehicles are made from plastic or ceramic, they will not stand up very well in collisions. Just think about a car lying in the side road destroyed pieces like a dropped ceramic object. Utilizing metal as the main body for the vehicle was purposefully and adequately chosen, but not all may think about why the element metal is such a right choice.

What is the smallest unit of matter that has characteristic properties of its element? 1.atom 2.molecule 3.gas 4.compound
Answer:
Atoms! An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms. Atoms are extremely small, typically around 100 picometers across. They are so small that accurately predicting their behavior using classical physics—as if they were tennis balls, for example—is not possible due to quantum effects.
