Identify the wrong match. (A) Mo - Nitrogen metabolism (B) B- Carbohydrate translocation (C) Zn - Auxin synthesis (C) Fe - Splitting of water

Question:

Identify the wrong match. 

(A) Mo - Nitrogen metabolism 

(B) B- Carbohydrate translocation 

(C) Zn - Auxin synthesis 

(C) Fe - Splitting of water

Answer: option (D) "Fe - Splitting of water".

Explanation:

Solution:

option (A): MO - nitrogen metabolism: 

The molybdenum nitrogenize is responsible for most biological nitrogen fixation, a prokaryotic metabolic process that determines the global biogeochemical cycles of nitrogen and carbon. 

option (B): B- Carbohydrate translocation: 

Boron is necessary for the translocation of sugar (carbohydrates) in plants. 

option (C): Zn - Auxin synthesis: 

Auxin is a growth hormone which is synthesized by tryptophan as a precursor by tryptophan-dependent auxin biosynthesis pathway. Zinc helps in the biosynthesis of auxin and its oxidative attack by free radical. It suppresses the production of oxygen during the synthesis of auxin and also acts as a coenzyme and activates the enzyme for auxin formation. 

option (D): Fe - Splitting of water: 

The enzyme has four Mn ions. Light energized Mn and removes electrons from OH- component of water forming oxygen. So, the essential element required for water splitting in photosynthesis leading to release of oxygen is Mn. 

Hence, the wrong match is option (D) "Fe - Splitting of water".

Fusion of dissimilar gamete is:- (i) Allogamy (ii) Fertilization (iii) Autogamy (iv) Dichogamy

Question:
Fusion of dissimilar gamete is:- 

(i) Allogamy 

(ii) Fertilization 

(iii) Autogamy 

(iv) Dichogamy

Answer: option (ii) "Fertilization".

Explanation:

Cross-pollination in a crop plant is known as allogamy. Allogamy is defined as fertilization of ovum of a flower by the pollen of another flower on the different plant. The pollen is transferred from the anther of a male flower to the stigma of a female flower. Allogamy takes place because of the male and female part of a particular flower mature at a different time. Dichogamy is a condition when the stamens and pistils of a flower mature at different times to prevent self-fertilization. Autogamy is the phenomena of fusion of gametes produced from the same individual. It involves the transfer of pollen from the anther to the stigma of the same flower. It is avoided when the number of seed is less, or the produced pollen is not able to fuse and germinate with the ovule of the same flower or the produced pollen are not healthy. Fusion of dissimilar gametes is fertilization. It takes place during sexual reproduction where the male and female gametes fuse to form a zygote. 

Hence, the correct answer is option (ii) "Fertilization".

Double circulation plays important role in maintenance of Homeostasis in human beings. Validate the above point giving the suitable explanation.

Question: 

Double circulation plays important role in maintenance of Homeostasis in human beings. Validate the above point giving the suitable explanation.

Explanation:

A circulatory path is a path taken by the blood , wherein it travels throughout the different organs of the body through arteries and veins. In humans, it is a closed circulatory system that exists, as blood flows in closed blood vessels. The circulatory system is responsible for the transport of gases, nutrients, waste products etc. 

The Circulatory System delivers oxygen and nutrients in the blood to the surrounding cells to maintain Homeostasis. The blood transports nutrients, oxygen, and water to other body cells throughout the body. is necessary for a human being to separate oxygenated and de - oxygenated blood because this makes their circulatory system more efficient and helps in maintaining constant body temperature.

The human circulatory system is a double circulatory system. It has two separate circuits and blood passes through the heart twice. the pulmonary circuit is between the heart and lungs.

Hence, double circulation plays an important role in maintenance of Homeostasis.

Question: Identify the wrong match. 

(a) MO - Nitrogen metabolism 

(b) B - Carbohydrate translocation 

(c) Zn - Auxin synthesis 

(d) Fe - Splitting of water

Answer:

wrong match option: (d) Fe - Splitting of water

Explanation:

Option (a):

MO - nitrogen metabolism:

The molybdenum nitrogenase is responsible for most biological nitrogen fixation, a prokaryotic metabolic process that determines the global biogeochemical cycles of nitrogen and carbon. 

Option (b):

B - Carbohydrate translocation:

Boron is necessary for the translocation of sugar (carbohydrates) in plants. 

Option (c):

Auxin is a growth hormone which is synthesized by tryptophan as a precursor by tryptophan-dependent auxin biosynthesis pathway. Zinc helps in the biosynthesis of auxin and its oxidative attack by free radical. It suppresses the production of oxygen during the synthesis of auxin and also acts as a coenzyme and activates the enzyme for auxin formation.

Option (d):

Fe - Splitting of water:

The enzyme has four Mn ions. Light energized  Mn and removes electrons from OH component of water forming oxygen. So, the essential element required for water splitting in photosynthesis leading to release of oxygen is Mn.

Hence, the wrong match is (d) "Fe - Splitting of water".

Which taxonomic category will have similar taxon in the classification of Mango and wheat? (a) Class (b) Division (c) Order (d) Family

Question: 

Which taxonomic category will have similar taxon in the classification of Mango and wheat? 

(a) Class 

(b) Division 

(c) Order 

(d) Family

Answer:

correct option: (b) Division

Explanation:

Taxonomic categories of Mango:

Class: Dicotyledonae

Division: Angiospermae 

Order: Sapindales 

Family: Anacardiaceae 

Taxonomic categories of wheat:

Class: Monocotyledonae

Division: Angiospermae

Order: Poales

Family: Poaceae 

So, by above conclusion it is clear that Division (Taxonomic category) have similar taxon in classification of mango and wheat.

Hence, the correct answer is option second "Division".

Fusion dissimilar gamete is (1) Allogamy (2) Fertilization (3) Autogamy (4) Dichogamy

Question: 

Fusion dissimilar gamete is.....

(1) Allogamy 

(2) Fertilization 

(3) Autogamy 

(4) Dichogamy 

Answer:

Correct option: (2) Fertilization

Explanation:

Cross-pollination in a crop plant is known as allogamy. Allogamy is defined as fertilization of ovum of a flower by the pollen of another flower on the different plant. The pollen is transferred from the anther of a male flower to the stigma of a female flower. Allogamy takes place because of the male and female part of a particular flower mature at a different time. 

Dichogamy is a condition when the stamens and pistils of a flower mature at different times to prevent self-fertilization.

Autogamy is the phenomena of fusion of gametes produced from the same individual. It involves the transfer of pollen from the anther to the stigma of the same flower. It is avoided when the number of seed is less, or the produced pollen is not able to fuse and germinate with the ovule of the same flower or the produced pollen are not healthy. 

Fusion of dissimilar gametes is fertilization. It takes place during sexual reproduction where the male and female gametes fuse to form a zygote. 

Hence, the correct answer is option (ii) "Fertilization".
