Answer:
The last answer
Explanation:
The sun is a perpetual resource because solar radiation steadily streams from the sun without interruption and is expected to do so for the next 6 billion years.
What do you mean by perpetual resource?Perpetual resources are those that last forever like solar energy and wind. Non-renewable resources, once extracted completely from a given area, will never be available in the same spot again (except after millions of years).
Perpetual resources are natural resources—such as solar energy, wind, and tides—that have no chance of being used in excess of their availability. They can be used for power generation and conversion to electric energy.
Sunlight, wind, geothermal heat, tides, and flowing water are perpetual resources. On Earth, there are only limited amounts of fossil fuels such as oil, coal.

Atom A has six protons , five neutrons and five electrons. Atom B five protons , six neutrons, and five electrons . Are atoms A and B of the same element ?
1. no, because they do not have the same number of protons
2. no, because they do not have the same number of neutrons
3. yes , because they have the same number of electrons
4. yes , because both have 16 protons , neutrons, and electrons combined
Answer:
no, because they do not have the same number of protons
Explanation:
No of protons represents atomic number which decides the characteristics of an atom . Two atoms having same number of protons but different number of neutrons are same element . They differ only in some physical characteristics . They are called isotopes . In respect of chemical properties they are same . In a neutral element number of protons and number of electrons are same . But in some case number of electrons may differ . In that case they form ions of the element . In positive ion , number of electrons is shorter than number of protons .
In the present case , atom A and atom B differ in respect of number of protons so they represent different element .
The setup shows four test tubes. Tube 1 contains water only. Tube 2 contains a live snail. Tube 3 contains a live green water plant. Tube 4 contains both a live green water plant and a live snail. We know that plants can photosynthesize. We also know the product of photosynthesis is the reactant of cellular respiration.
In this setup, which tubes contains and organism(s) carrying on cellular respiration?
a) tubes 2 and 4, only
b) tubes 3 and 4, only
c) tubes 2, 3, and 4 only
d) tubes 1 and 2, only
pls help as fast as u can! <3
Answer:
c) tubes 2, 3, and 4 only
Explanation:
Cellular respiration is a metabolic process in which cells of living organisms break down organic molecules to synthesize or release energy in form of ATP. Because all cells require or need energy (ATP) for their functioning, cellular respiration is carried out by ALL LIVING ORGANISMS.
According to this question involving four test tubes that contain the following:
- Tube 1 contains water only.
- Tube 2 contains a live snail.
- Tube 3 contains a live green water plant.
- Tube 4 contains both a live green water plant and a live snail.
Cellular respiration will be carried out in the test tube that contains any living organisms. These test tubes are test tubes 2, 3 and 4 as they contain live green plants and snail.
What is the shoal of sardines? What other fish can make shoals?
The shoals are often more than 7 km long, 1.5 km wide and 30 metres deep and are clearly visible from spotter planes or from the surface. Sardines group together when they are threatened. This instinctual behaviour is a defence mechanism, as lone individuals are more likely to be eaten than large groups.
The shoaling habit includes all the popular, common fish that belong to the Characin family (tetras), Cyprinidae family (barbs and danios) and Melanotaeniidae family (rainbow fish). There are even some species of catfish and cichlids that shoal.
Why do fish swim in shoals?Many kinds of fish prefer to swim together in groups called shoals. ... Shoaling can help fish because there are more eyes for spotting danger from predators or for finding food. Predators also find it more difficult to target a single victim in a big, moving group.

what a Lunar Phase ?
Answer:
It’s something like The lunar phase or Moon phase is the shape of the Moon's directly sunlit portion as viewed from Earth. The lunar phases gradually change over a synodic month as the Moon's orbital positions around Earth and Earth around the Sun shift
Answer with Explanation:
A lunar phase is also known as a "moon phase." This refers to how we see the Moon in different shapes as it is reflected back to Earth. Such reflection depends on the portion of the Moon that is illuminated by the sun. This explains why the amount of moon that we view from Earth changes over time.
It consists of 8 phases: New Moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full Moon, Waning Gibbous, Third Quarter and Waning Crescent.

Mary poured 40,000 cm3 of water into an aquarium that
is shaped like a rectangular box. If the length and width
of the aquarium are 40 cm and 80 cm, respectively, what
is the height, in centimeters, of the water in the
aquarium?
Answer:
The correct answer is - 12.5 cm3.
Explanation:
Given:
volume = 40000 cm3 (aquarium an hold water)
length and width = 40 cm and 80 cm
Height = ?
Formula:
Volume = length*width*height
Solution:
Putting the value in the formula -
40000 = 40*80*h
h = 40000/3200
h = 12.5

Answer:
interphase
Explanation:
Interphase is the most important phase of cell life cycle where it spends 90 percent its time in regulating the metabolic activities of the cell. In this phase cell undergoes several metabolic activities to maintain the growth of the cell.
There are three phases in interphase G1, S and G2. During this phase cell undergoes several changes that include cell grows, DNA replicates and prepare itself for mitosis.
Hence, the answer is "interphase".

Pls, Hurry up? True or False + Explain. "Sea anemones are sessile organisms and stay permanently attached to their substrate."
Answer:
True
Explanation:
Sea anemones are one of the numerous predating animals found in the marine environment. They have cylindrical bodies whose bases are usually found attached to substrates and are therefore described as being sessile. However, a few species of sea anemones are known to be free swimmers.
Generally, sessile organisms are those that live their life attached to a substrate and, therefore, are not able to freely move about.
Answer:
True
Explanation:
This is because sea anemone polyp is permanently attached to the beneath of the base where it stay by it base called pedal foot. It sometimes glide around in order to prevent itself from predation and it uses it's tentacle to catch moving food particles around it and consume it. It belong to the group cnidaria.
Suppose a ship sinks in the middle of the ocean and it has a cargo of 28,000 rubber ducks. Instead of the ducks staying where the boat sunk at, the rubber ducks began to find their way to different coastlines as shown in the picture below. What do you think is causing the ducks to move in this pattern?
Answer:
Currents moving the ducks with them.
Answer:
Kind of Know
Explanation:
Tectonic plates shift all of the time, thats why we have oceans where we have oceans. So, the rubber ducks moed along the ocean patterns based off of the tetonic plates. I am pretty sure, hope this helps :).
