Answer:
An ionic bond.
Explanation:
A strong electrostatic force of attraction will develop between the oppositely charged ions. For example, sodium chloride (salt) is essentially made of a positively charged sodium ion and a negatively charged chloride ion. 
 
        
             
        
        
        
Answer:
a. a female reproductive structure
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction. 
Division Antophyta are classified into two (2) main categories and these includes;
I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc. 
II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc. 
Basically, fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit. 
 
        
             
        
        
        
Actually it is the females the mostly build the nests the males will help build it sometimes both males and females will build it but typically it is females and that goes for all birds. 
"Females typically build nests, but sometimes both parents or just the male"
 
        
             
        
        
        
note:
Gymnosperms possess several key evolutionary innovations compared to earlier groups such as the clubmosses and ferns. They produce sperm-containing pollen, which is carried through the air by the wind to the female. This innovation has freed these plants from the need for water for sexual reproduction.
 
        
                    
             
        
        
        
Answer:
True 
Explanation:
Almost all cells have a nucleus. Haemoglobin is red blood cell but has no nucleus, prokaryotes have plasmid and not a nucleus sooo... Yea
