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.

How does crossing over increase variation in genes?
When cells divide during meiosis, homologous chromosomes are randomly distributed to daughter cells, and different chromosomes segregate independently of each other.
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.

Which is a sustainable practice? Operating wind farms or clear cutting or flood irrigation or overfishing
Answer:
A
Explanation:
EDG 2020
An example of sustainable practice is the operating wind farms. Thus, the correct option will be A.
What is Sustainable practice?Sustainable practices can be referred to as the practices which support ecological, human, and economic health and also the vitality. Sustainability usually presumes that all the available resources are present in finite amount, and should be used conservatively and wisely with a view to have long-term priorities and consequences of the ways in which the available resources are used.
Wind power or wind farms are one of the most efficient technology to produce energy in a very safe and environmentally sustainable manner. It is zero emissions, local, inexhaustible, competitive source of energy and it also creates wealth and jobs for a large group of people.
Therefore, the correct option will be A.

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.

which do you prefer to use organic fertilizer or inorganic fertilizer explain
Answer:
Organic fertilizers continue to improve the soil long after the plants have taken the nutrients they need. Therefore, the longer your soil is fed with organic fertilizers, the better its composition and texture. So, while inorganic fertilizer is cheaper in the short term, it adds less to the soil in the long term.

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.
