Answer:
True
Explanation:
Evolution is the change in the characteristics of a population over generations. This is caused by nature selecting out some disadvantageous traits and preserving advantageous traits over successive generations through natural selection pressures. In this case, the white moth is at a disadvantage in the environment compared to the black moth. The allele for white color is, therefore, ‘weeded out’ over time.

describe 2 observation of water that provide evidence that water molecules are attracted to one another
The capillary action and water's solubility property demonstrate the attraction between water molecules. The former is seen when water ascends a straw or capillary tube because of water's adhesive properties. The latter is shown when substances like table salt dissolve in water due to the strong attraction between polar water molecules and the ions in salt.
Explanation:There are two clear observations that provide evidence that water molecules are attracted to one another. These observations refer to the water's property of adhesion and cohesion.
Firstly, the phenomenon called capillary action demonstrates how water molecules are attracted to each other. This effect is observed when water climbs up a straw or capillary tube, which occurs because water molecules are more attracted to the charged surfaces of the tube than to each other, inducing the water to adhere to the tube's surface and move upward.
Secondly, water's solubility property provides another evidence of the attraction between water molecules. For instance, when you dissolve table salt in water, the polar water molecule's attraction to the ions (Na+ and Cl-) in salt overcomes the ionic bond in the salt, resulting in its dissolution. Conversely, non-polar substances like oils do not mix with water, because the attraction among water molecules is stronger than the attraction between water and oil molecules.

Julie’s town uses single-stream recycling, so Julie puts all of her household recyclables in a single container to be picked up. The recycling plant must sort out the different materials, including paper, cardboard, different types of plastic, glass bottles and jars, aluminum drink cans, and steel food cans.
How would an electromagnet be used in this type of recycling plant?
to remove plastic bottles from glass bottles
to divide food cans from soft-drink cans
to separate paper from cardboard
to gather colored glass from colorless glass
Answer:
to divide food cans from soft-drink cans
Explanation:
An electromagnet is based on the principle that current through a coil produces magnetic field. Magnetic objects such as Iron, nickel, cobalt or objects made from their combination are attracted by the magnet. This property is used to separate materials in recycling plant.
Steel (alloy of iron) would be attracted by the magnet where as aluminium would not be. Thus, steel food cans can be separated from the aluminium soft-drink cans using an electromagnet.

The summer solstices occurs around June 21st and is the longest day of the year in the northern hemisphere. On this day, the Sun is as far ______ as it will get at sunrise and sunset. A) east B) north C) south D) west
Answer:
B) north
Explanation:
On June 21st we have the summer solstice in the Northern Hemisphere. This is the longest day of the year in the Northern Hemisphere and officially it marks the beginning of the summer. On this date, the sun gets the furthest north during sunset and sunrise on the Northern Hemisphere. This is the case because that is when the Northern Hemisphere is the most tilted and exposed to the sunlight. Basically, the further north the Sun appears on the sky in the Northern Hemisphere, the more sunlight there will be and the higher the temperatures will be as well.

Hydrilla (Hydrilla verticillata) is an invasive aquatic plant and one of the most serious aquatic pests in Florida. Hydrilla has already been introduced to hundreds of bodies of water throughout Florida. Hydrilla is difficult to control because it grows rapidly and survives in many different water depths and conditions.
Part A: Describe how hydrilla affects native plant and animal species. Include both a biotic and an abiotic limiting factor.
Part B: Suggest one biotic and one abiotic recommendation that could slow the spread of hydrilla.
Part A: Invasive species displace native species in their habitat hence reducing biodiversity that is necessary for a balanced ecosystem. This is because invasive species do not have a natural predator in their new environment and hence their growth is unchecked. They, therefore, take up much of the nutrients and other biotic factors utilized by the other species.
Part B; To deal with invasive species, one can introduce a predator of the invasive species into the environment. Another is the influencing a limiting factor (usually an abiotic factor) that affects the invasive species specifically. These will check the unregulated growth of invasive species and preserve the ecosystem’s biodiversity.

Which is not a property of water?
Select one:
a. good solvent for electrolytes
b. high specific heat
c. adheres to polar compounds
d. contracts during freezing
d. Because when liquid water becomes solid ice, it expands, not contracts.
Water contract during freezing is not a property of water.
Option D
Explanation:
The water at normal temperature is fluid in nature where the disorder in the structure is due to the hydrogen bond between the molecules of water which are continuously forming with one molecule and then again forming with another molecule.
When the water freezes then due to low temperature the energy of the system is lost due to which vibration between the element is also reduced and hydrogen bonds no longer change. At this time the fixed hydrogen bond causes the molecules of water to expand which further decreases the density of water.

C. It is quite likely because both the caiman and parrot have had amniotic eggs and they share recent common ancestor with the T. Rex.
D. Probably not because the T. Rex is no longer living.
I’m failing biology, help a girl out!
I know that It has an amniotic egg so It is either B or C
Final answer:
The T. Rex most likely had an amniotic egg, as it is a characteristic of amniotes. Close relatives of the T. Rex, like the caiman and parrot, have had amniotic eggs, indicating that the T. Rex probably had them too.
Explanation:
The T. Rex most likely had an amniotic egg. Amniotic eggs are a characteristic of amniotes, which include reptiles, birds, and mammals. The evolution of amniotic eggs allowed for the development of embryos within an aquatic environment inside the egg, which reduced the dependence on a water environment for development. Although the T. Rex is no longer living, its close relatives, such as the caiman and parrot, have had amniotic eggs, indicating that the T. Rex probably had them as well.
How much faster is the Arctic warming compared to the rest of the world?
Answer:
Twice
Explanation:
According to the latest studies about the global warming and how it affects part of the world, the research has shown that the Arctic is warming up twice as fast as the rest of the world. This should not really come as a surprise as the Arctic is not consisted of land mass, but instead of ocean water. The ocean water needs slightly lower temperature to freeze, so it is easier for it unfreeze. Once it unfreezes it moves and it becomes part of the global water circulation patterns. This results in bring in more warmth to the Arctic through the ocean currents, which also results in more melting of the ice, so the rate of warming up is constantly increasing.
Which of the following must be true in a dry limestone cave? Select all that apply. A. Water once entered the cave. B. The cave was formed by volcanic means. C. Any cave formations are no longer growing. D. There must only be stalagmites, no stalactites.
Option b is correct..
Caves are formed by the dissolution of limestone. Rainwater picks up carbon dioxide from the air and as it percolates through the soil, which turns into a weak acid. This slowly dissolves out the limestone along the joints, bedding planes and fractures, some of which become enlarged enough to form caves.
Identify the statement about meiosis that is incorrect
Select one:
a. Pairing of homologous chromosomes
b. Four haploid cells are formed
c. At the end of meiosis the number of chromosomes are reduced to half
d. Two cycle of DNA replication occurs
Answer:
the answer is d)
Explanation:
i think the reason why it is d) is because during meiosis the there shouldn't be any dna that are carbon copies because all living things that are made sexually has different dna ( except identical twins of course)
The incorrect statement about meiosis is 'd. Two cycles of DNA replication occurs.' In reality, DNA replication occurs once before Meiosis I, after which two rounds of cell divisions create four haploid cells.
The statement about meiosis that is incorrect is: d. Two cycles of DNA replication occurs. In meiosis, DNA replication occurs only once, during the S phase of the cell cycle prior to the first meiotic division. Following this, there are two rounds of cell divisions known as Meiosis I and Meiosis II, which result in four haploid cells from one diploid parent cell. During Meiosis I, homologous chromosomes pair up and may exchange genetic material through crossing over. Afterwards, these homologous chromosomes are separated into two cells. Meiosis II resembles mitosis where the sister chromatids within the two daughter cells are separated, resulting in a total of four haploid cells. These events ensure that at the end of meiosis, the number of chromosomes is reduced to half in each of the four haploid cells produced.
Which MOST LIKELY represents the gas being released and the process used to make it?
I believe that the gas is Carbon dioxide and that it is being released by respiration.
The gas being released is carbon dioxide and in the process called cellular respiration.
In apparatus set up by the students, the yeast used the sugar in the apple juice together with the oxygen to generate adenosine triphosphate (ATP) and releases carbon dioxide as a waste.
Further ExplanationYeast is a one-celled organism that requires energy to survive. Yeast can do anaerobic and aerobic respiration. For yeast to survive, it has to make its energy.
To survive, yeast uses cellular respiration, where glucose is transformed into ATP and carbon dioxide.
In other words, cellular respiration is a metabolic process that involves the breaking down of glucose to generate adenosine triphosphate (ATP) and releases waste products. The waste product is carbon dioxide (C02)
Cellular respiration is used by both plants and animals to break down sugar and convert it into energy. The energy produced is used by plants and animals to carry out some task at the cellular level. The essence of cellular respiration is to provide the energy required for cells to function.
Therefore, in the apparatus set up by the students, the yeast used the sugar in the apple juice together with the oxygen to produce adenosine triphosphate (ATP) and discharges carbon dioxide as a by-product.

A. Every 11 years
B. Every two million years
C. Every 100,000 years
D. Every 350 days
Answer:
A. Every 11 years
Explanation:
It happens at the peak of each solar cycle as the sun's inner magnetic dynamo re-organizes itself. The coming reversal will mark the midpoint of Solar Cycle 24.
The sun's magnetic field reverses A. Every 11 years.
The Sun's magnetic field undergoes a complete reversal of its polarity approximately every 11 years. This phenomenon is known as the solar magnetic cycle or the solar cycle. The cycle starts with the Sun's magnetic field being oriented in a particular direction, and over the course of about 11 years, it gradually flips its polarity, with the north and south magnetic poles interchanging.
The solar magnetic cycle is driven by the complex processes occurring within the Sun's interior. It involves the generation and interaction of magnetic fields through processes such as differential rotation, convection, and the dynamo effect. These processes generate and amplify the magnetic fields, leading to the periodic reversal of the Sun's magnetic polarity.
Therefore, the correct answer is A. Every 11 years.
