What are periodic properties?Periodic Properties: Periodic properties are those that exhibit a regular gradation as we travel from left to right inside a period either from top to bottom inside a group and are either directly or indirectly connected to their electrical arrangement.
Atomic size, ionization energy, electron affinity, electronegativity, polarity, density, atomic volume, melting, and other essential periodic features are only a few. Elements W and Z are metals, Elements X and Y are nonmetals, but Element X is in Group 18 (noble gas).
Therefore, the correct option is option A.

The stars appear to move across the sky every day, but
their paths change throughout the year. Here is a model of
the Sun-Earth system.
Based on the model, which three factors might cause this change in the
apparent movements of the stars?
Answer:
Earth's Revolution around the sun, The tilt of Earth's Axis, and Earth's rotation on its axis.
Explanation:
I have done this test
1. The Earth's revolution around the Sun: As the Earth revolves around the Sun, the stars appear to move across the sky each day. This is because the Earth is rotating on its axis, which causes the stars to appear to be moving from east to west.
2. The Earth's tilt: The tilt of the Earth's axis also has an effect on the apparent movement of the stars. As the Earth rotates around the Sun, the tilt of the Earth's axis changes throughout the year. This causes the stars to appear to move slightly differently at different times of the year.
3. The Precession of the Equinoxes: The precession of the equinoxes is the gradual wobble of the Earth's axis which takes place over thousands of years. This has an effect on the apparent movement of the stars, as the angle of the Earth's axis changes over time. This causes the stars to appear to move in a slightly different pattern than they did thousands of years ago.

Select the methods and results that best illustrate sustainable crop intensification.
GMO drought-tolerant seeds
low pesticide use
high-yield, low ecological impact
heavy use of irrigation
low cost
high cost
high use of synthetic fertilizer
high labor
Answer:
GMO drought-tolerant seeds, high use of synthetic fertilizer, high-yield, low ecological impact.
Explanation:
Crop rotation is one of the most powerful techniques of sustainable agriculture. Its purpose is to avoid the consequences that come with planting the same crops in the same soil for years in a row. It helps tackle pest problems, as many pests prefer specific crops.
If the oceans of the earth got warmer from global warming, would the water of the oceans become more or less salty?

Marianne is conducting an experiment on homeostasis in paramecium which is a type of single celled organism. Which of these observation
Answer:
Contractile vacuole is responsible for maintaining the homeostasis in paramecium.
Explanation:
The observation of this experiment is that contractile vacuole is responsible for maintaining the homeostasis in paramecium because the contractile vacuole regulates the quantity of water inside a cell. Contractile vacuole controls the water balance in the body by absorbing and removing the excess amount of water out of the cell. This function of contractile vacuole allows the cells to survive under hypotonic stress that is present in the pond water or any other stressful environment.

If the DNA molecule is only composed of four possible nitrogen bases, how can thousands of different proteins be formed from such a limited set of fixed shapes?
Answer:
nucleotides are only building blocks whose combinations determine different codons which subsequently associate in a sequential manner in order to create different amino acid combinations
Explanation:
A gene is a specific segment of DNA whose (nucleotide) sequence is copied into an RNA during the process of transcription, typically a messenger RNA (mRNA) molecule which is subsequently used to synthesize a protein. During translation, each triplet of nucleotides, i.e., each codon, corresponds to a specific amino acid. There are 64 possible codons (4³: 64), which can combine in different ways to create different amino acid combinations, and thus they are responsible for the generation of a huge amount of proteins coded by a given genome.
