Answer:
<h2>D</h2>
Explanation:
Photosynthesis occurs in plants and in some other autotrophs, in which they synthesize their food own-self in the presence of sunlight.
They take CO₂ from environment, water from roots and light form sun. Then they produce carbohydrate and O₂.
Chlorophyll capture sunlight and convert this into chemical energy, through which sugars are produced.
Plants produce O₂ which animals use in their respiration.
Answer: The fertilized egg divides and the cells differentiate to become all of the different cell types of a human, the DNA molecules of the fertilized egg must be duplicated over and over, so that each of our trillions of cells contains an exact copy of the DNA contained in the fertilized egg.
Answer:
Chlorophyll A, and B.
Explanation:
Chlorophyll is known as the green pigment which is present in plants. Through the process of photosynthesis, It helps to convert solar light into useful energy. They have light absorption properties, so they are known as photoreceptors. Mainly two types of Chlorophyll are present in plants:
Chlorophyll A: It Is known as the primary photosynthetic pigment and has the ability to absorbs red, blue, and violet lights. Chlorophyll A is the location of the photochemical processes and can absorb light which is needed for the process of photosynthesis.
Chlorophyll B: It mainly helps to absorb blue light which is utilized to fill out the absorption of chlorophyll A it means it helps to supply additional light energy to chlorophyll A. It is known as the accessory pigment.
"The predominant ingredient of the inorganic matrix of bone is calcium salts, with the majority existing as large molecules of hydroxyapatite crystals" is TRUE.
<u>Option: A</u>
<u>Explanation:</u>
- A significant element of normal bone and teeth and an essential ingredient.
- Hydroxyapatite compensates the mineral bone and teeth matrix.
- It is hydroxyapatite which brings its stiffness to bones and teeth.
- The inflammation triggered by crystals with hydroxyapatite was referred to as crystal disease with hydroxyapatite.
- Hydroxyapatite, also termed hydroxylapatite, is a found naturally in calcium apatite mineral type.
- A well-recognized unexplained etiological systemic problem named as "Hydroxyapatite crystal deposition disease (HADD)" has been caused by para-articular and/or intra-articular HA crystal deposition.
