Answer:

its the first one 6CO2 + 6H20 ===> C6H12O6 + 602

Explanation:

The correct chemical equation for photosynthesis is shown below:

6CO₂ + 6H₂0 ===> C₆H₁₂O₆ + 60₂

Thus is the process in which green plants manufacture food in the presence of sunlight.

It makes use of materials which can be seen in the balanced equation shown above thereby making option A the most appropriate choice.

Answer:

Convection currents form because a heated fluid expands, becoming less dense. ... As it rises, it pulls cooler fluid down to replace it. This fluid in turn is heated, rises and pulls down more cool fluid. This cycle establishes a circular current that stops only when heat is evenly distributed throughout the fluid.

Explanation:

Convention currents work by forming a heated fluid expanding making it less dense.  As the current rises, it pulls cooler fluid down to replace it.

Answer:

Endothermic reaction

Explanation:

Photosynthesis is an endothermic reaction because sunlight is being absorbed during the reaction and the definition suggests that in a reaction if heat is being absorbed it is termed as an endothermic reaction.

Answer:

The mass of a substance is constant according to the law of conservation of mass.

Explanation:

According to the law of conservation of mass, matter can never be created or destroyed in a chemical reaction, even though it may undergo change from one physical state to another.

This means that in an isolated or closed system, the mass of matter will always be the same irrespective of the type of change that matter undergoes. This is so because, the mass of a substance is a measure of the quantity of matter in that substance and is constant. The number of particles does not change during a change of state, only their spacing and arrangement. In solid ammonia, the particles are more compact and arranged, whereas in gaseous ammonia, they are more randomly spaced out.

The given question is incomplete as the genotype of the parents is not given, so the answer is providing in the followings case: 1. dominant parent and recessive parent 2. heterozygous parents Answer: 1. dominant parent and recessive parent: dominant parents can be represented by LL and recessive parent is represented by II, so the gametes would be L, L and I, I. so, LL LI LI LI so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue. 2. heterozygous parents In this case, parents have LI genotype and gametes would be L and I for each parent so, L I L LL LI I LI I|so there are all offspring in heterozygous condition as we known one or two dominant allele masks the recessive allele for the trait so 100% offspring can fold their tongue. 2. heterozygous parents In this case, parents have LI genotype and gametes would be L and I for each parent so, L I L LL LI I LI I| In this case, one is pure dominant and two heterozygous whereas only one is recessive the phenotype of offspring that cant fol the so, tongue would be: 75% = 3/4

Explanation:

For a Hurricane to keep going it needs to have hot air constantly going up and cold air coming down. When it gets to land, it loses access to the heat and moisture of the sea which is greater than on land. This forces it to weaken and to eventually dissipate.

Therefore, hurricanes disperse after making landfall because land is not as hot as the ocean water.

Answer:

Cell walls never take the place of a cell membrane

Explanation:

The cell wall has a texture that is tough, flexible, and occasionally hard and is found outside the cell membrane, hence option C is correct.

Plant cells' outside layer is called the cell wall. Only plants and some types of bacteria, fungi, and algae have cell walls.

Bacteria, algae, fungi, most plant cells, and certain archaea all have cell walls. A cell wall is a structure that surrounds the plasma membrane or cell membrane in cells that have them.

Cellulose or chitin are the main components of the cell wall, which is a stiff, semi-permeable structure.

Glucans, chitin, and glycoproteins make up the majority of the cell wall, which is a distinctive structure of the fungus.

Therefore, cell walls never take the place of a cell membrane.
