Ques.1. A solution of a substance 'X' is used for whitewashing.

Biology
1 answer:
Deffense [45]2 years ago
4 0

The name of this substance 'X' that is used for whitewashing is calcium oxide or quicklime.

<h3>What is whitewashing?</h3>

Whitewashing can be defined as a technique used in painting which typically involves the use of a substance that reacts with air and water (H₂O), thereby, forming a white plaster on surfaces.

In this context, the name and formula of this substance 'X' that is used for whitewashing is calcium oxide (CaO) i.e quicklime.

The properly balanced reaction of calcium oxide (CaO) and water (H₂O) is written as follows:

                              CaO + H₂O ------> Ca(OH)₂ + heat

Which statement describes how pioneer species and climax communities are different?
Lorico [155]

Answer: D). Primary species have large numbers of offsprings, and climax communities contain species that have small numbers of offsprings.

An ecological succession is a process of gradual changes occurs in a biological community with respect to changes in the non-living abiotic factors  (water, air and sunlight) and with respect to time until the ecosystem attains stability. Primary or pioneer species are the species which invade the previously barren and primitive landmass for their survival. These species make the environment suitable for the growth of other species. These grow and develop in the initial stages of succession. These species are simple organisms which reproduce asexually and produces large number of offsprings. Examples are lichen and moss. Lichen grows on the surface of rocks and acids released by them causes withering of rocks into soil which facilitate the growth of mosses and other plants. Climax community develops in an ecosystem after replacing many previously inhabiting species. Climax community develops in the end of the ecological succession. It contains species which are highly complex and uses sexual reproduction for the production of offsprings which are less in number as compared to those produced by pioneer species by asexual reproduction.

Identify the phenotypes for the offspring of a parent with the genotype IBi and a parent with the genotype IAIA. type O type A,
agasfer [191]
 <span>I is dominant, i is recessive. The A's and B's are just show which allele I is. When there is just one dominant allele, it masks the recessive in blood typing. Remember IA and IB are codominant. 

O is always ii 
A is IAi (heterozygous) or IAIA (homozygous) 
B is IBi (heterozygous) or IBIB (homozygous) 
AB is always IAIB 

Remember: You get one allele from each parent! 

1. Father must be ii, mother must be ii, so all children must be ii. 

2. Father is IAIA (the homozygous one), the mother is IBIB, so the only possibility for the children is IAIB, because you get one allele from the father and one from the mother. 

3. Father is IAi, mother is IBi, so the children can be any of the blood types, because they can have all the combinations of genotypes. 

4. Father is ii, mother is IAIB. Children can only be IAi or IBi. 

5. Father is IAIB, mother is IAIB. Children can be IAIA, IBIB, or IAIB. 

Example of Punnett square: 
3. Father is type A, heterozygous, mother is type B, heterozygous 
Father must be IAi (heterozygous) 
Mother must be IBi (heterozygous) 

_______IA ____ i 

IB____ IBIA____IBi 

i _____ IAi______ii 

Sorry, that was difficult on here, hope it's understandable. 
The father's alleles run across the top, the mother's are on the side, you follow to where they meet to find the possibilities for the children. IBIA (AB blood type), IBi (B), IAi (A), and ii (O) are the possibilities in this case. 

Hope that helps!</span>
