Which of the following statements correctly compares terrestrial and Jovian planets?
А
Jovian planets are generally warmer due to their proximity
to the Sun.
B
Terrestrial planets have longer
periods of revolution.
С
Terrestrial planets are denser due to their rocky composition.
D
Jovian planets are smaller in diameter.
Answer: C
Explanation: terrestrial planets are denser then the Jovian (Outer) planets since they are mostly made of rocky material, while the Jovian planets are gaseous.
Saturn, for example, would theoretically be able to float in water due to its low average density.
Fill in the blank: Chemical weathering is the_____ of rock into one or more new compounds.
Answer: Transformation
Explanation:
A flower has the gene for the colors red and blue. The blue gene is dominant over red. If a plant breeder crossed a red flower with a blue flower, what will the offspring phenotype be?
Answer:
Explanation:
Let blue gene be BB
Red gene be bb
Since blue gene is dominant the allele is B
while red gene that is recessive has allele b
A cross between the two individual will give,
BB × bb
!
Bb Bb Bb Bb
Genotype=Bb
Phenotype= all blue flowers
Where the offspring have blue flower and non have a red flower.

farming practices that expose topsoil to water and wind often result in which degraded the soil and can ultimately threaten food production
Answer:
Soil erosion and lost of fertility.
Explanation:
The farming practices that expose topsoil to water and wind often result in erosion of the soil because the wind and water takes particles with them. If water and wind removes the soil particles continuously then the land become barren and lost its fertility which leads to lower production of food crops that ultimately threaten the food production for the population.

Explain why the size of a new moon would affect the appearance of a solar eclipse.
Answer:
A solar eclipse can occur only when new moon occurs close to one of the points (known as nodes) where the Moon's orbit crosses the ecliptic. ... Therefore, the Moon's apparent size varies with its distance from the Earth, and it is this effect that leads to the difference between total and annular eclipses.

How do you think the rock layers and fossils found in Red Rock Canyon can provide evidence for Earth's geologic history?
Answer and Explanation:
Red Rock Canyon is an area of universal geologic interest, located a few miles west of Las Vegas within the Mojave Desert. Many experienced geologists visit the Red Rock; they are surprised by the vivid colors of rocks, natural beauty, and rock formations. A visual display takes million years to make the masterpiece known as the Red Rock Canyon National Conservation area. About 500 million years ago, Red Rock Canyon was found at the bottom of an ocean basin. Limestone accumulated in this ocean basin, which contains the fossils of sea life. The tracks of two-footed meat-eating dinosaurs have been found in the Aztec Sandstone. The tracks of small animals such as spiders, scorpions, early mammals, and proto-mammals were also found. The fossils and rock layers that are found in Red Rock Canyon provide evidence for Earth’s geologic history. Paleontologists are still searching these areas.
Based on your observations would you SUPPORT OR REFUTE The following statement “Eclipses occur at the same place on Earth every time”. Please make sure to backup your answer with an observation or fact.
Describe and explain the purpose of phototropism and gravitropism in plants and explain why this feature is important for the survival of plants (6 marks)
QER question so marks for spelling etc too but if anyone has bullet points of things to include that would be great! :)
Answer:
Plants have a variety of developmental, physiological, and growth responses to light—sometimes only to particular wavelengths of light.
In phototropism a plant bends or grows directionally in response to light. Shoots usually move towards the light; roots usually move away from it.
In photoperiodism flowering and other developmental processes are regulated in response to the photoperiod, or day length.
Explanation:
there are some key points, hope that helps :)
Two positively charged objects (Object A and Object B) are 8 inches apart. When a positively charged ball is hung at an equal distance between the two positively charged objects, the ball moves toward object B (see figure).
What can you conclude about the relative amount of positive charge on Object A and Object B? Provide support for your claim.
Your answer:
Answer:
Object B has more charge than Object A
Explanation:
Generally, unlike charges attract each other and like charges repel each other but it happens in a very rare case when like charges attract each other. It is so due to charge difference between the objects.
In the given example a positively charged ball moves towards positively charged object B because object B has more charge than object A and the ball. Due to large difference in the charges between two positive charges, positive charges are displaced at opposite end and object B get concentrated with negative charges that allows ball to move towards Object B.
Hence, the correct answer is "Object B has more charge than Object A".

Is there stored energy in a candle?
Answer:
Yes.
Explanation:
The burning candle is converting chemical energy—stored in the hydrocarbon bonds in the wax—into thermal (heat) and radiant (light) energy. The energy transforms from chemical energy to heat and light energy. Because when the candle burns a chemical reaction occurs, and produces heat and light
How do all of the parts of this organism work together in order for it to function properly? Explain your answer.
Answer:
Humans—and other complex multicellular organisms—have systems of organs that work together, carrying out processes that keep us alive.
The body has levels of organization that build on each other. Cells make up tissues, tissues make up organs, and organs make up organ systems.
The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food.
The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.
Explanation:
brainliest?
The basic components of the complex human organism is made up of cells. Its level of organization are coordinated with each other to perform specific function.
what are the level of organization ?The primary chemical level of organization include atoms, ions, and small molecules which are joined to form macromolecules; The macromolecule include larger molecule like amino acid, carbohydrate, fats, nucleic acid where the basic components are carbon, hydrogen and oxygen atoms.
This macromolecule act as biomolecule at cellular level, the cellular level include the smallest unit of living organism, it can be unicellular and multicellular in nature based on complexity of the organism.
The tissue level of organization include a number of cells are gathered together and perform a specific function called tissue like epithelial, connective, muscular tissue.
The organ level include groups of tissues which work together to perform a higher-level function like stomach, heart etc; The organ system include all of the organs involved in doing a vital function, like digestive system, circulatory system,
In this way a complex organism perform their activities.

The concept of emergent property definition
Answer:
definition
Explanation:
An emergent property is a property which a collection or complex system has, but which the individual members do not have. In biology, for example, heart is made of heart cells, heart cells on their own don't have the property of pumping blood.
