Positive, Negative or no effect can a chromosomal change can have on an organism. So, the correct option is (A).
What is Chromosomal change?When there is an increase or loss of chromosome number from the normal number of chromosomes which is 46, it is called aneuploidy. A common form of aneuploidy is trisomy which is the presence of an extra chromosome in cells.
"Tri-" is Greek for "three" which define as the people with trisomy have three copies of a particular chromosome in their cells instead of the normal two copies.
Chromosomal abnormalities can occur when an accident occurs when the egg or sperm are being formed or during the early developmental stages of the embryo. Maternal age and certain environmental factors may play a role in the occurrence of genetic errors. There are Positive, negative, or no effect in the chromosomal change.
Thus, Positive, Negative or no effect can a chromosomal change can have on an organism. So, the correct option is (A).

Life can exist under frozen surfaces in polar seas because…
Answer:
Life exit under frozen surfaces in polar seas because of the anomalous behavior of water.
Explanation:
Water behaves irregularly, which helps in preventing the total freezing of seas during winter.
Since water has its highest density at [tex]4^{o}[/tex]C, the surface of seas freezes while the lower regions or layers is in form of liquid. During winter, as the temperature decreases to [tex]4^{o}[/tex]C, the layer of water with highest density sinks to the bottom while those that are less dense floats to the top. Thus when the surface temperature is below [tex]0^{o}[/tex], the lower layers under the frozen surface are at temperature range between [tex]1^{o}[/tex]C to [tex]4^{o}[/tex]C

Which statement about earth is accurate? Select the two correct answers 1. A few hundred earthquakes per year are strong enough to be detected by instruments. 2. More than 1 billion earthquakes happen per year. 3. Fewer than 100,000 earthquakes happen per year. 4. About 100 earthquakes per year are strong enough to cause damage. 5. Most earthquakes are not strong enough to be felt by human.
Answer:
the answer is 5 and 3 i had a question like this and i got it right i hope im right
Explanation:
About 100 earthquakes per year are strong enough to cause damage, while most earthquakes are not strong enough to be felt by humans. So, the correct options are (D) and (E).
What is Earthquake?An earthquake is defined as a sudden release of strain energy in the Earth's crust which results in waves of vibration that radiate outward from the earthquake source. When the stress in the crust exceeds the strength of the rock, it tends to break along lines of weakness, either pre-existing or new fault planes.
Earthquakes occur very frequently as the Earth's tectonic plates are always move and they collide or brush against each other which creates stress that is regularly released in the form of earthquakes. About a million earth tremors occur every year that are undetectable to humans, where they are 2.4 on the Richter and lower in magnitude. Therefore, every year there are about 100 earthquakes above 6.0 Richter magnitude that cause damage.
Thus, about 100 earthquakes per year are strong enough to cause damage, while most earthquakes are not strong enough to be felt by humans. So, the correct options are (D) and (E).

a skaterboarder is traveling 12 m/s down a hill. The skaterboarder cradshed and slid to a stop in 2.0 seconds. What was the rider's acceleration?
PLEASE!!!
The skateboarder is travelling with a initial velocity of 12 m/s and slid to stop in the next 2.0 seconds. The acceleration of the skateboarder will be -6 m/s².
What is Acceleration of an object?Acceleration of a body is the change in the velocity with respect to time. Acceleration depends upon factors such as time, initial velocity, final velocity, and distance travelled by the object.
In the given question, the skateboarder is travelling with a initial velocity (u) of 12 m/s
Time (t) after which he comes to a stop is 2.0 seconds
The skateboarder stops and comes to rest therefore, the final velocity (v) of the skateboarder will be zero
The acceleration (a) of the skateboarder can be calculated by the formula:
a = (v - u)/t
where, a = acceleration of the object
v = final velocity of the object
u = initial velocity of the object
t = time elapsed
a = (0 - 12)/2.0
a = -12/2.0
a = -6.0m/s²
Here, the acceleration is negative because the body comes to rest at the end after acceleration.

A student is measuring the lengths of caterpillars for an experiment. She measures 100 caterpillars using a ruler that measures to the nearest centimeter. Which statement describes a change that could help improve the results of her experiment? O A. Her measurements will be more precise if she measures an additional 100 caterpillars. O B. Her measurements will be more accurate if she measures an additional 100 caterpillars. O C. Her measurements will be more accurate if she uses a ruler that measures to the nearest millimeter. O D. Her measurements will be more precise if she uses a ruler that measures to the nearest millimeter Please help
Answer:
B and C
Explanation:
The student's measurement would be more accurate if she can measure an additional 100 caterpillars and be more precise if she uses a ruler that measures to the nearest millimeter.
Accuracy refers to the closeness of measurement or group of measurements to the true value while precision is the closeness of repeated measurements.
The accuracy of a measurement is increased by increasing the number of sample measurements. The more the sample measurements, the lesser the deviation of the mean from the true value.
The precision of a measurement is increased by being able to measure small differences. Hence, a ruler that measures to the nearest millimeter would be more precise than a ruler that can only measure in centimeter.
The correct option is B and C.
