Explain the difference between the first day of spring (vernal equinox) and the first day of summer (summer solstice).
I will give you a brainliest!!!!
Answer: Vernal equinox(about March 21): day and night of equal length, marking the start of spring. Summer solstice (June 20 or 21): longest day of the year, marking the start of summer.
vernal = spring
solstice = summer
Answer:
See explanation
Explanation:
The first day of spring (March 20) means the first day of the growing season. it also has some cold temperatures, rain and sun. The first day of summer (June 20 or 21) means the first day of school break. summer has sun, which you will need to wear summer clothes.
vernal = spring
solstice = summer

From new moon phase to full moon phase, what do you see?
1. a decreasing amount of the lighted side of the Moon
2. the same amount of the lighted side of the Moon
3. an increasing amount of the lighted side of the Moon
I need an answer ASAP!! I will give you a brainliest!!
Answer:
I believe the answer is number 3: an increasing amount of the lighted side of the Moon.
Explanation:
When the Moon changes from new Moon to full Moon, the lighted side is shown more and more, increasing from the right side to the left until you can see the whole lighted side. This would mean you would see an increasing amount of the lighted side of the Moon.

Mendel carried out a dihybrid cross to examine the inheritance of the characteristics for seed color and seed shape. The dominant allele for yellow seed color is Y, and the recessive allele for green color is y. The dominant allele for round seeds is R, and the recessive allele for a wrinkled shape is r. The two plants that were crossed were F1 dihybrids RrYy. Identify the ratios of traits that Mendel observed in the F2 generation. Create a Punnett square to help you answer the question.
Simply create a dihybrid cross, and then create ratios from the outcomes. Remember that ratios only come from the bottom part of any fractions *If you need more help on dihybrid crosses I can send an example image
Dihybrid cross is a experiment including mating between two organisms, that are identically hybrid for two traits. The ratios of traits in F2 generation will be 9:3:3:1.
What is Punnett square?Punnett square is the square diagram used to identify the genotype of the cross in experiment.
Genotype is the collection of genes and phenotype is the physical appearance of the individual. The Punnette square for the given case will be creates as given in the image attached.
Thus, the ratio of traits will be 9:3:3:1 in the F2 generation.

A hammer can be used to see how a mineral breaks. If you observe square chunks of the mineral when broken, what can you conclude?
The mineral is soft.
The mineral is hard.
The mineral has cleavage.
The mineral does not have cleavage.
Answer:
The mineral has cleavage
Explanation:
Cleavage describes the shape of internal planes of weakness between the molecules that make up a mineral, often forming 3-D geometric shapes like cubes and prisms. When a mineral breaks, it will commonly break along these cleavage planes regardless of how hard or soft the mineral is.

Which statement best describes how this puddle demonstrates that matter is too small to be seen without magnification?
The light causes a reflection to appear on the surface of the water.
The person cannot see the bottom of the puddle.
The twig floats on top of the puddle of water.
The water cannot be seen when it evaporates.
Answer:
The twig floats on top of the puddle of water.
Explanation:
The twig will almost seem like magic. Because water is clear its hard to understand matter holding the twig up. But under a microscope you are able to see the qualities of water and the building blocks of matter.
The twig floats on top of the puddle of water best describes how this puddle demonstrates that matter is too small to be seen without magnification. The correct option is C.
Thus, The inability of the individual to see the puddle's bottom proves that the matter (in this case, the water's constituent particles) is too small to be seen without a magnifying glass.
Because the water droplets are so tiny and tightly packed, light cannot penetrate through the puddle to expose its bottom.
This finding emphasizes how tiny the individual particles are that make up matter.
Thus, The twig floats on top of the puddle of water best describes how this puddle demonstrates that matter is too small to be seen without magnification. The correct option is C.

Compare an elephant’s trunk with a person’s hand. How are they similar? How are they different?
Answer:
one way that they are different is that unlike us humans they don't have fingers on their trunk. one way that they are similar is that both use something to pick objects up.
Explanation:
hope this helps you!
Both the elephant trunk and human hands are used to grasp objects.
The Elephant's trunk is the part of the elephant that extends outwards from its face and enables the elephant to pick up things. It is quite similar to the human hands in the sense that it can be used to grasp objects.
However, human hands are made of fingers but the trunk of an elephant is just a long structure that has no fingers. Hence, it is different from the human hands.

What factors determine the type of rocks that forms underground?
1.The amount of heat present
2.The amount of water present 2 out of 3 numbers are correct
or 3.The type of minerals that combine
Answer: the answer is (d)
Explanation:
The initial rocks that form an underground rock that was melted and the history of the molten rocks' cooling are the two main elements that affect the formation of igneous rocks.
What factors affect the rock's formation?
After a rock has been fractured, the fragments of rock and minerals are carried away by a process known as erosion.
The type of igneous rocks that form from magma depends on three factors, the chemical composition of the magma, the temperature at which solidification takes place, and the rate of cooling, which affects the crystallization process.
Therefore, factors determine the type of rocks that forms underground forces of weathering and erosion, and Magma's chemical makeup is subject to change.

How do genetically modified foods affect society and the environment?
Answer:
Genetic modification produces genetically modified animals, plants and organisms. This could result from differences in nutritional content, allergic response, or undesired side effects such as toxicity, organ damage, or gene transfer.
Explanation:
existing species can be overrun by more dominant new species.
One important environmental impact of genetically modified (GM) foods is the threat to biodiversity resulting from the genetic transfer from GM crops to native plant species.
Which correctly lists three characteristics of minerals?
A) solid, crystal structure, definite chemical composition
B) organic, crystal structure, definite chemical composition
C) human-made, solid, organic
D) crystal structure, definite chemical composition, human-made
Answer:
A
Explanation:
Minerals are naturally-occurring, inorganic, solids with a crystal shape/structure.
Hope that helps!!
Solid, crystal structure, definite chemical composition lists three characteristics of minerals. Therefore, option (A) is correct.
Minerals are non-artificial solids. They have a crystal structure that repeats atoms. Minerals contain certain elements in defined proportions. These traits help identify and classify minerals.
Other choices misrepresent minerals. B) includes "organic," which alludes to living organisms, while minerals are usually inorganic. C) contains "human-made" and "organic," which minerals are not. D) says "human-made," but minerals develop naturally in the Earth's crust. Therefore, option (A) is correct.
