Answer:
All the statements are true except the second i. e. the soil quality in an ecosystem Does not matter as much as soil quantity.
Explanation:
In an ecosystem both quality and quantity of water is very important. If the quality of water is not suitable, that it contains polluted substances so the health of the organism such as fishes and other aquatic animals will adversely affected and sometimes dealth occurs and the ecosystem will be negatively affected.
Answer: competition
Explanation:
Competition is an ecological interaction in which two organisms interact with each other in order to obtain the same resource. The resource can be food, shelter, mate or other. The competition can be intraspecies which means the members of the same species compete for the resources. The competition can be interspecies which means members of the two distinct species compete for the same resource. Generally the competition leads to the decrease in growth, abundance and distribution of members of the inferior species and the members of the superior species derives the resources.
Answer:
1. The gametophyte generation is haploid.
2. The embryo is diploid.
3. The megaspore is haploid.
4. The sporophyte generation is diploid.
Explanation:
1. Gametophyte- The gametophytic generation is the structure which produces gametes in the plant. Since the gametes are haploid, therefore, the gametophyte us considered the haploid.
2. Embryo- The embryo is formed after the fusion of fertilization when zygote develops, therefore, is considered diploid.
3. Megaspore- the big size spore which is formed from by the meiotic division of the megasporocyte, therefore, is considered haploid.
4. Sporophyte- the sporophyte generation develops from the embryo which is diploid therefore is considered diploid.
I'll say that it is +1 since hydrogen is desperate to lose an electron to fulfill the octave rule (that the molecules want to gain 8 electrons and if they can't do it, they want to lose all their electron). Electron is - so if it lose a electron, it becomes +.
Hopefully this helps.
PS. I'm not certain of my answer but it is logical.
