During ______, the gravitational forces of the sun and moon pull on the Earth from the same direction, or opposite dire
Answers
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.

Construct an argument based on data about the risks and benefits of renewable and nonrenewable energy resources.
Argument should consist of at least 100 words.
Answers
Non-renewable energy resources are available in limited supplies, usually because they take a long time to replenish. The advantage of these non-renewable resources is that power plants that use them are able to produce more power on demand. The non-renewable energy resources are:
Coal
Nuclear
Oil
Natural gas
Renewable resources, on the other hand, replenish themselves. The five major renewable energy resources are:
Solar
Wind
Water, also called hydro
Biomass, or organic material from plants and animals
Geothermal, which is naturally occurring heat from the earth
While renewable energy resources have the advantage of unlimited supply over the long haul, they are limited in their availability at any given moment.
For example, the sun rises each day, but its ability to generate power is limited when its cloudy. Another disadvantage is that power plant operators can’t crank up renewable energy production when people are consuming more power, such as on a hot day when many people are running air conditioners at the same time.
States like California are trying to solve this problem by using energy storage, like large batteries, to collect electricity from renewable sources when demand is low in order to use it later when demand goes up. Non-renewable Energy and Climate Change
When coal, natural gas and oil are burned to produce energy, they emit heat-trapping gases such as carbon dioxide. This process of trapping heat is what drives climate change, and the failure to address this problem is what's catalyzing the current climate crisis.
Fossil fuels are hydrocarbon-containing materials like coal or gas that are found in the Earth’s crust and formed in the geological past from the remains of living organisms. These energy sources account for the majority of the world’s greenhouse gas emissions.
If emissions continue unrestrained, the atmosphere could warm by as much as 2.7 degrees Fahrenheit above preindustrial levels by the year 2040, according to the latest report from the Intergovernmental Panel on Climate Change, a group of international scientists empowered by the United Nations to advise world leaders.
Scientists say this increase in the temperature would threaten life on the planet in a myriad of ways, including severe water shortages; more air pollution; rising sea levels, habitat loss; heat waves; melting ice sheets in West Antarctica and Greenland; and destruction of the world’s coral reefs.
Over the last 150 years, humans are responsible for the vast majority of the increase of these gases in the atmosphere, and the burning of fossil fuels through activities like driving a car is the largest source of these emissions.
There is a vocal group of environmentalists and researchers —Stanford’s Mark Jacobson, who developed a state-by-state 100% renewable plan for one — who argue that the power grid should be supported only by renewable resources.
Policy makers who invest in renewable energy often do so with the goal of generating power without emitting these planet-warming gases. Hope this helps!

Answer:
Flowers not only look pretty but, in fact, are important in making seeds. Flowers have some basic parts. The female part is the pistil. The pistil usually is located in the center of the flower and is made up of three parts: the stigma, style, and ovary. The stigma is the sticky knob at the top of the pistil. It is attached to the long, tubelike structure called the style. The style leads to the ovary that contains the female egg cells called ovules.

Answers
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

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
Answers
Answer:

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.

Answers
An experiment must include variables. The other three are just measurements, but since the scientist is varying the types of fertilizers used, this better describes an experiment. It is also done in a controlled environment (in a lab) which helps to eliminate other uncertainties.

Answers
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.
