Which correctly lists three forms of frozen water?
O dew, frost, rain
O frost, hail, sleet
O hail, rain, sleet
Orain, dew, frost
Answer:
b
Explanation:
The option that correctly lists three forms of frozen water is "frost, hail, sleet". Therefore, option (B) is correct.
What is frozen water?Frost is created when water vapor condenses and freezes onto a surface, like the ground or a window.
Hail is produced when powerful updrafts in thunderstorms carry raindrops high enough that they freeze into ice, forming large balls of ice that fall to the ground. This process results in the formation of hail.
Sleet is created when raindrops pass through a layer of cold air close to the ground. This causes the raindrops to freeze into small ice pellets before they reach the ground's surface.

After an ionic bond is formed, what is the charge of the atom that gained an electron?
Answer: Negative
Explanation:
This is called an anion. Whenever an atom gains a electron, it becomes negative. When an atom loses an electron, it becomes postitive. Positive atoms are called cation.
After an ionic bond is formed, the charge of the atom that gained an electron will be negative.
What is an ionic bond?An ionic bond, also widely recognized as an electrovalent bond, is a category of interconnection established by the electrostatic attraction of ions with opposing charge in a chemical substance.
When the valence (outermost) electrons of one atom are permanently transferred to another atom, a bond is formed.
An ionic bond is formed between a metal and a nonmetal, whereas a covalent bond is formed between two nonmetals.
An ionic bond is formed by the complete transfer of electrons from one atom to another. When an atom loses one or more electrons, it becomes a cation, or positively charged ion.
When an atom gains one or more electrons, it becomes an anion, a negatively charged ion.
Thus, the atom is negatively charged as it gained electron.

3. Approximately when was
the Moon full?
Answer:
When the Sun and the moon directly align.
Explanation:
At Full Moon, the entire face of the Moon is illuminated by the Sun's rays and it can be bright enough to light up otherwise dark nights.
Technically, this primary Moon phase only lasts a moment, the instant when the Sun and the Moon are aligned on opposite sides of Earth (see illustration). So the exact time for Full Moon is during the day on parts of the planet.
However, the Moon can appear to be full a day before or after while more than 98% of the Moon's disc is illuminated.
Therefore, it can be difficult to tell the difference between a Full Moon and the last stage of a Waxing Gibbous Moon or the beginning of a Waning Gibbous Moon.

1. How do you think rapid changes in the chracteristics of habitats affect the niches of
animals occupying that habitat?
Answer:
The rapid changes would make an organism change their land, environment around them, and the food web
When the habitat of the animals living in it changes, both the animals and the habitat change. It changes the biotic and abiotic factors of the niche and ecosystem. Habitat is part of a niche.
What is the impact of the changing habitat?
Niche is a broad space in which the particular animal roams, searches for food, and reproduces, but habitat is a part of the niche where the animal spends most of its life. Human interventions, such as cutting down forests for industry, roads, and so on, have an impact on wildlife. Due to this, the temperature of the earth keeps on increasing, resulting in climate change, global warming, the melting of ice, a rise in water levels, etc.
If these changes happen, then animals will have difficulty living in their habitat. The environment will not be favorable for living, and both abiotic and biotic factors will be disturbed, such as the fertility of the soil, which is affected by fewer trees. Other animals affect by this change too.
Hence, in this way, the change in habitat changes the niche.

Answer: The fluid mosaic model describes the structure of the plasma membrane as a mosaic of components —including phospholipids, cholesterol, proteins, and carbohydrates—that gives the membrane a fluid character. Plasma membranes range from 5 to 10 nm in thickness.
Explanation:
The option that describes the fluid mosaic model of the plasma membrane is a lipid bilayer with protein molecules dispersed within it.
It should be noted that the fluid mosaic model of the plasma membrane was proposed by Singer and Nicholson to explain the structure of the plasma membrane.
The plasma membrane is known as a fluid model because it has several types of molecules that float along the lipids. The fluid mosaic model of the plasma membrane is made up of two layers of lipid molecules where there are protein molecules dispersed within.
