What is produced when calcium reacts with fluorine in a synthesis reaction? Ca + F2 →

Answers

Answer 1
Answer:

The right answer is CaF2

Calcium fluoride is an inorganic compound of formula CaF2. This ionic compound consisting of calcium and fluorine is naturally present in nature in the form of fluorine (also known as fluorite). It is the world's leading source of fluoride.

It is a solid insoluble in water, whose structure is cubic where each atom of calcium is adjacent to eight atoms of fluorine, and each atom of fluorine to four atoms of calcium.

Answer 2
Answer: CaF2 is the correct answer

These light and heat energy are then used for photosynthesis and other cell processes.

Plant can go through photosynthesis because they contain chloroplasts.  A chloroplast is an organelle found only in plant cells and which enables photosynthesis to occur.

Insides chloroplasts, there are  found structures called thylakoids also known as grana or stroma. It is these thylakoids that contain chlorophyll, the green pigment that helps capture light energy from the sun which provides the fuel to run the first stage of photosynthesis.

How many wings do housefly have?

Answers

Answer:

one pair

Explanation:

Houseflys are like Diptera

Final answer:

Houseflies have two wings.

Explanation:

Houseflies, like many other insects, have two wings. These two wings are the primary flight appendages of the housefly and are attached to the thorax, the middle section of the insect's body. The presence of two wings is a characteristic feature of the order Diptera, to which houseflies belong.

The two wings of a housefly are typically transparent and membranous, allowing for flight. In addition to their two wings, houseflies also have two small, club-shaped structures called halteres located behind the wings. Halteres serve as sensory organs and are essential for the housefly's stability and balance during flight.

The presence of two wings and two halteres is a defining characteristic of true flies, which are members of the order Diptera. These wings play a crucial role in the housefly's ability to fly and are an integral part of their anatomy.

Which best describes the cycle that ensures fresh water, which is vital for carrying out metabolic processes, is available?A.
carbon emission, photosynthesis, respiration

B.
evaporation, condensation, precipitation

C.
evaporation, respiration, transpiration

D.
run-off, precipitation, flooding

Answers

Answer: B.  evaporation, condensation, precipitation

Explanation:

The Hydrological Cycle is the process by which water moves from the surface to the atmosphere and then back again. It is important for various reasons one of which is that it is vital for carrying out metabolic processes.

The cycle involves the evaporation of water from the surface which turns water into water vapor. This vapor then becomes liquid and forms clouds when it gets to the atmosphere in the condensation process.

It then falls back down to the surface when the clouds formed become too heavy in the process of precipitation/ rain.

Describe the relationship between DNA and chromosomes

Answers

When a cell needs to duplicate, DNA strands are tightly coiled into chromosomes (chromosomes are made up of DNA and protein). Genes are certain stretches of DNA that code for a certain protein with a specific bodily function. On a chromosome, the location of the gene is called a locus. 
DNA contains all the genetic material that decides a person's traits, such as hair color, eye color, etc. The DNA also passes on traits from the parents to the offspring, which is why children always have common traits with their parents. Genes carry the information needed to pass on these traits. 
In summary, DNA, genes, and chromosomes are very similar in their 'composition', since genes are stretches of DNA that codes for certain proteins and chromosomes are made up of coiled DNA. Their functions are the same in the sense that they are all vital in passing on traits from the parent to the child, and therefore in determining the physical traits of the offspring.
