How do parents' traits predict the offspring? (Explain)
Answer:
A trait is a characteristic, such as color or size, that is inherited by an offspring from its parents. The genes that control a trait come in pairs, one gene from each parent. If a gene pair contains a dominant allele, then the offspring will show this dominant trait.
Why is it important for cells to buffer solutions against rapid changes in pH? What does a buffer do?

Explanation:
what are two purposes of the cell cycle
Answer:
The most basic function of the cell cycle is to duplicate accurately the vast amount of DNA in the chromosomes and then segregate the copies precisely into two genetically identical daughter cells.
Explanation:
The purpose of cell cycle, To regulate the cell division according to need of a cell. It helps in dividing and growing the new cells in multicellular organisms.
What are the different stages of cell cycle ?A series of events occurs in a cell leads to the duplication of DNA and division of cytoplasm to produce two daughter cells called as cell cycle.
It consist up two phases interphase and M phase.
Interphase is the cell's resting phase, where cell prepare its self ready for cell division, it consist of 3 sub phases G1, S, G2.
In gap 1, metabolically active cell continues to grow without DNA replication.
In S phase, DNA replication occur and the centriole divides into two centriole.
G2 phase, the RNA, proteins, other macromolecules needed for other cell organelle multiplication.
M or mitotic phase cell under go mitotic division to give rise to equal chromosome number containing progeny.

Weather and climate are affected by ocean currents because they
A. are caused by Earth’s rotation.
B. cause upwellings along certain coastlines.
C. move large volumes of water vertically in the deep ocean.
Answer:
C.
Explanation:
What causes currents in the ocean.Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth's rotation results in the Coriolis effect which also influences ocean currents.Ocean currents act as conveyer belts of warm and cold water, sending heat toward the polar regions and helping tropical areas cool off, thus influencing both weather and climate.The tropics are particularly rainy because heat absorption, and thus ocean evaporation, is highest in this area.

Which organelle turns solar energy into chemical energy? Question 1 options: Golgi Apparatus Endoplasmic Reticulum Chloroplast none of the above
Answer:
Structure of the Golgi bodies in a plant cell. A typical plant cell organelles include Cell wall, Cell membrane,converts water, carbon dioxide, and light energy into nutrients for lack the chloroplast pigments, they are found in non-photosynthetic parts
Explanation:
The organelle that turns solar energy into chemical energy is chloroplast. The correct option is C.
Chloroplasts are organelles that may be found in plant cells and some types of algae. They are in charge of the process known as photosynthesis, which transforms solar energy into chemical energy.
The chlorophyll pigment in the chloroplasts absorbs sunlight and transforms it into chemical energy in the form of glucose via a series of intricate processes.
This process is the main method by which solar energy is transformed and stored in living organisms, and it is essential for the synthesis of food and oxygen in plants. Chloroplast is the right response as a result.
Thus, the correct option is C.

During chemical weathering what can happen to the type of rock that has undergone chemical weathering.
A. No new rock is created just smaller in size. B. A new rock is produced that is different from the original rock. C. A new rock is produced that is the same as the original rock. D. A new rock is produced that is larger than the original rock
Answer:
A new rock is produced that is different from the original rock.
Explanation:
During chemical weathering, a new rock is produced that is different from the original rock.
Chemical weathering is the chemical decomposition of rocks to form sediments and soils. A large chunk of rock combines with water, air and other chemical materials. This cause chemical action and a new substance is produced. This process is known as chemical weathering.Physical weathering is the breaking down of rocks into smaller fragments.
Chemical weathering leads to the formation of a new rock is produced that is different from the original rock that has undergone chemical weathering is formed.
Weathering refers to the process by which rocks break down. The weathering of rocks may be chemical, physical or mechanical. Chemical weathering refers to the breakdown of rocks due to the action of chemical agents.
During chemical weathering a new rock is produced that is different from the original rock that has undergone chemical weathering is formed.
