Answer: B. geocentric and
C. circular motions of planets
Explanation:
Aristotle's model: He thought that earth was center universe. And this universe made up only four elements.
Ptolemy's model: He thought that earth was center of universe and all celestial objects including sun, planets and moon were orbiting the around the earth. And earth did not move at all.
Aristotle's and Ptolemy's models of the solar system suggest the geocentric and circular motions of planets.
Ptolemy model of the solar system was a geocentric model. Ptolemy thought that the universe was a set of nested spheres surrounding the Earth.
Aristotle's model shows the planets moving around the Earth in an orderly manner, in uniform circular motion, neither speeding up nor slowing down.

What genotypes are observed when you cross a Dd parent
with another Dd parent?
a. 100% DD
b. 75% DD and 25% dd
c. 50% DD and 50% dd
d. 25% DD, 50% Dd, 25% dd
Answer:
it is D. 25%DD ,50%Dd ,25%dd
If both the parents are heterozygous (Dd), the resulting offspring are 25%DD, 50%Dd, and 25%dd. So, the correct option is D.
What do you mean by genotypes?Genotypes may be defined as the ultimate combination of alleles of those genes which are selected for our study.
Here, both the parents carry the genotype Dd, when Dd is crossed with Dd, the resulting offspring are 1DD, 2Dd, and 1dd.
Therefore, if both the parents are heterozygous (Dd), the resulting offspring are 25%DD, 50%Dd, and 25%dd.

Two type O people are married. Select each blood type that is possible for their natural children.
A
B
AB
O
Answer:
Type o is the most possible
Explanation:
Let's use a punnet square. A and B are dominate, while O is recessive. If one parent has A and the other O, then most likely the blood type is O. But since both are o, then it's only possible for O.

Consider two ocean waves A and B. A has an amplitude of 5 Units and B has an amplitude of 12 units. Compare their energy
Answer:
12 units.
Explanation:
There is a direct relationship between amplitude and energy. if amplitude of the wave increases, the wave has more energy while on the other hand, if the amplitude decreases, the energy of the waves also decreases. Direct relationship means one increases the other automatically increases and vice versa. So due to this direct relationship, the wave having 12 units amplitude has higher energy as compared to the wave having amplitude of 5 units.

Photosynthesis takes place in leaves. Leaves contain that allow for the exchange of gases during the process, and also help with the process of .
Answer:
The correct answer is - stomata, transpiration.
Explanation:
Photosynthesis is the process that uses light to convert CO2 and water to produce sugar and oxygen. The carbon dioxide is taken up by the little holes-like structures present on the spongy layer of the leaves called stomata. These structures are used for gaseous exchange, taken up oxygen, and releasing oxygen.
Stomata also help in releasing water vapors from the aerial parts during the process of transpiration to prevent the plants to burn in a dry environment and wind.

Which statement best describes the motion of the plates along these boundaries that causes the earthquakes? The plates push apart from each other with no subduction. Subduction occurs with the less-dense plate sinking below the other plate. Subduction occurs with the more-dense plate sinking below the other plate. The plates smash together with no subduction.
Answer:
D). The plates smash together with no subduction.
Explanation:
As per the question, the last statement most adequately demonstrates the movement of plates i.e. 'the plates hit together without any detraction' through concurring boundaries causing the earthquakes to take place. The continuous smashing of tectonic plates with one another leads to the development of a pressure towards both the rock layers by the time this stress is released through a shaky or convulsive movement of the Earth. Thus, option D is the correct answer.
What effect does deforestation have on the environment?
A increased oxygen in the atmosphere
B increased carbon dioxide in the atmosphere
c decreased oxygen in the geosphere
D decreased carbon dioxide in the atmosphere
Answer: its definitely B or C i think that it might be C
Explanation:
As more trees are removed there is less trees to remove the Carbon Dioxide from our atmosphere.
This means that there are less trees producing Oxygen which almost all living organisms need to survive which will decrease the amount of Oxygen in The Geosphere
The Geosphere is any of the almost spherical concentric regions of matter that make up the earth and its atmosphere, as the lithosphere and hydrosphere.

Name one type of substance that is taken into a root hair cell using active transport.
Answer:
The substance taken in is mineral salts.
One type of substance that is taken into a root hair cell using active transport is nitrate ions, calcium ions, etc., as these are the ions that are not easily passed through the cell membrane and are taken into the cell by spending energy.
What is the significance of the active transport in the cell?Active transport in the cell that requires energy for the transportation of the substances, and active transport is significant because it allows cells to maintain the necessary concentration gradients. Mineral ions such as nitrate and calcium ions, which are required for plant growth, are actively transported in root hair cells.
Hence, one type of substance that is taken into a root hair cell using active transport is nitrate ions, calcium ions, etc., as these are the ions that are not easily passed through the cell membrane and are taken into the cell by spending energy.
