The four factors are availability of food, water, shelter and space. The effect they have on the population includes: lower birth rates, increasing death rates or leading to emigration
Answer:
A. Water molecules have strong intermolecular attractions.
Explanation:
Water molecules have strong intermolecular attractions due to the presence of hydrogen bond between oxygen and hydrogen atoms. This hydrogen bond is present between hydrogen of one water molecule to the oxygen of another water molecule. This hydrogen bond is weaker than covalent bond so that's why it can be broken down and water is converted into vapours form by heating.

Answer:
The correct answer is D: diploid phase
Explanation:
The essence of plant life is their characteristic property of alternation of generations. Each plant undergoes alternation of generations and produces haploid and diploid generations.
This property allows the plant to reproduce both sexually and asexually. Primitive plant species used to reproduce through spores and spent the majority of their life as haploid cells. These cells were called as spores and required only matter and energy to reproduce.
Modern plant species reproduce by using gametes and spent the majority of their life in diploid phase called diploid sporophytes.
