Meiosis produces haploid gametes, and fertilization creates a diploid cell that divides by mitosis to produce a new individual.
Understanding meiosis
One method of cell division is meiosis. Reporting from the official website of the Ministry of Education and Culture of the Republic of Indonesia, meiotic division only occurs in the sex organs.
The function of Meiosis is to produce gametes (egg cells and sperm cells). This division produces daughter cells that have half the chromosomes of the parent cell.
The number of chromosomes possessed by daughter cells is n or is called haploid. Hence, meiotic cell division is referred to as reduction division.
Meiosis is a cell division thatthat produces 4 daughter cells, each of which has half the number of chromosomes of the parent cell.
And while body cells carry a total of 46 chromosomes, gamete cells only carry 23 chromosomes. A healthy young adult male will produce several hundred million gametes each day. In women, sex cells or ovum development follows a long process, starting in the fifth month after the woman is conceived. Meiosis begins at this stage, but stops at the egg precursor cell stage – or primary oocyte – during fetal development.

According to appearances, Green had the least amount of plant growth, while Blue had the greatest.
According to Petronus's (2016), for photosynthesis to occur, a cellular component like the pigment must be present because it gives plants their colour and traps sunlight in the process. The light spectrum, which is employed in most virtual labs for experimentation, has a tendency to have both long and short waves that contain various colours. Chlorophyll helps the photosynthesizing plant capture both blue and red light, according to Couto.

which characteristic makes hemoglobin's structure such a good match for its function as an oxygen carrier
The characteristic makes hemoglobin's structure such a good match for its function as an oxygen carrier is that each hemoglobin molecule can bind four oxygen molecules.
What is hemoglobin?The iron-containing oxygen-transporting metalloprotein known as hemoglobin, often known by the abbreviations Hb or Hgb, is found in the red blood cells of almost all vertebrates as well as some invertebrate organs. The oxygen from the respiratory organs is transported to the rest of the body by hemoglobin in the blood.
What is the characteristic of hemoglobin?Hemoglobin is a two-way respiratory carrier that facilitates the movement of carbon dioxide back and forth from the lungs to the tissues. Hemoglobin's affinity for oxygen in arterial circulation is high, but its affinities for carbon dioxide, organic phosphates, hydrogen, and chloride ions are low.
Thus from above conclusion we can say that the characteristic makes hemoglobin's structure such a good match for its function as an oxygen carrier is that each hemoglobin molecule can bind four oxygen molecules.

The graph shows the progress of a chemical reaction with and without the presence of an enzyme. Analyze the data. Which statement accurately reflects what is shown in the graph? A. The presence of the enzyme decreases the activation energy. B. The presence of the enzyme decreases the change in free energy. C. The presence of the enzyme decreases the energy of the products. D. The presence of the enzyme prevents the reaction from progressing
The difference between reactions mediated or not by enzymes, is the speed at which they occur, and hence, the required activation energy. A) The presence of the enzyme decreases the activation energy.
What are enzymes?Enzymes are proteins with intracellular catalytic properties that accelerate different natural chemical reactions. These reactions occur naturally, but they are accelerated in the presence of the enzyme.
Enzymes are in charge of catalyzing cell metabolism. Since they are proteins, they need an accurate tridimensional structure to accomplish their function. There is a limited temperature and pH level at which they lose that structure and denaturalize.
Concerning the reaction, in the enzyme's presence and absence, the substrate and the product are the same.
The main difference is the activation energy required to carry out the reaction.
Let us remember that activation energy is the one required to create or break bonds between molecules. Usually, the higher the activation energy is, the slower the reaction occurs.
In the presence of the enzyme, the reaction needs a lower activation energy than in its absence.
Without the enzyme ⇒ higher activation energy ⇒ slower reaction With the enzyme ⇒ lower activation enegy ⇒ faster reaction
According to this framework, the correct option is A. The presence of the enzyme decreases the activation energy.
