Answer: D
Explanation:
Quantitative type of result the student calculate in this experiment.
What is Quantitative type of results?Quantitative research is based on the collection and interpretation of numeric data. It focuses on measuring (using inferential statistics) and generalizing results.
The student have no hypothetical formula to calculate the actual strength of the web of both spider, so he always use to get quantitative type of result in his results.Hence option D is correct.

Explain how the sun determines climate distribution. What type of weather conditions does the sun control?
Answer:
The rate of energy coming from the Sun changes slightly day to day. It has been suggested that changes in solar output might affect our climate both directly, by changing the rate of solar heating of the Earth and atmosphere, and indirectly, by changing cloud forming processes
The Sun warms our planet, heating the surface, the oceans and the atmosphere. This energy to the atmosphere is one of the primary drivers our weather. Our climate is also strongly affected by the amount of solar radiation received at Earth.
Humans are in the group of living organisms that has the highest percentage of

A. True
B. False
Thank you!

During ______, the gravitational forces of the sun and moon pull on the Earth from the same direction, or opposite dire
Answer:
Spring Tides.
Explanation:
Tides can be defined as the rise and fall of water level in water bodies such as lakes and oceans due to the gravitational force of attraction exerted by the moon on earth. The side closest to the moon creates a bulge of water known as high tide. Low tides are generally experienced when a sea level is not within the bulge.
Generally, the gravitational pull of the Moon cause visible changes on planet Earth's surface.
This ultimately implies that, the pull of the Moon's gravity causes high and low tides on planet Earth's surface.
The various types of ocean tides based on the position of the Earth, Moon and the Sun are;
I. Neap tides.
II. Spring tides.
III. Low tide.
IV. High tide.
V. Brown tide.
VI. Rip tide.
VII. Red tide.

Which is a pollutant associated with high-tech gadgets in landfills?
A. Carbon Dioxide
B. Oxygen
C. Lead
D. Nitrogen
The pollutants associated with the high tech-gadgets or e-waste include mercury, lead, cadmium, etc. So the correct answer is option C.
An electronic device that has reached the end of its usable life cycle is called as the electronic waste or the e-waste. The electronic waste contains a lot of toxic compounds inside them and should be handled carefully because this e-waste releases the toxic pollutants in the environment which can cause air pollution and also has an impact on respiratory health.
Burning of e-waste can release fine particles (pollutants) into the enviroment which can cause chronic diseases and cancers as well.

Answer:
The process of nerve impulse transmission by means of an action potential involves the processes of depolarization, repolarization, hyperpolarization and restoration of resting memebrane potential.
Explanation:
In order for a neuron to receive and transmit a message it must be in a polarized state. While in this rest state there are more sodium ions outside the cell membrane while potassium is prevalent inside the cell. This causes the neuron to maintain a neutral charge. Once the action potential arrives at its dendrites, a nerve cell will shuttle the message down its own axon and to the next neuron via its axon terminal. This impulse will cause the cell to become depolarized and will effectively change the charge of the neuron to a poositive charge. After sodium rushes into the cell, the potassium will rush out in order to restore its resting memebrane potential. Once the impulse reaches the axon terminal, it is used to open voltage- gated calcium channels releasing calcium ions that stimulates a neurotransmitter to continue the message to the next neuron. The neuron then undergoes a repolarisation when all ions are repositioned with help of the voltage-gated ion channels.

what is the water intake of gymnosperms
Answer:
Check down
Explanation:
Gymnosperms, like angiosperms (the flowering plants), differ from seedless plants (like mosses and ferns) in not requiring water for sperm to swim in to reach the egg. This means that the movement of pollen (male gamete) to ovule (female gamete) in seed plants relies on airborne transport, not water transport.
A system releases 7.9kj of heat while 6.5kj work is done on it. Calculate
A system releases 7.9kj of heat while 6.5kj work is done on it. Calculate the total change in internal energy during these operations in kJ.
Answer:14.4kJ
Explanation:
The first law of thermodynamics which states that the total change in internal energy (ΔU) of a system is the sum of the total heat (Q) released by the system to its surroundings and the total work done (W) on the system by its surrounding, can be expressed mathematically as follows:
ΔU = Q + W -------------------(i)
From the question;
Q = 7.9kJ
W = 6.5kJ
Substitute these values into equation(i) as follows;
ΔU = 7.9kJ + 6.5kJ
ΔU = 14.4kJ
Therefore, the change in internal energy is 14.4kJ
