Answer:
Sponges are the members of the phylum Porifera. They have cellular level of body organization and they are sedentary. The space, food and other resources are limited. This leads to lot of competition for space among the sponges. Some of the sponges produce toxins to stop other sponges from settling down nearby or very close to another one. Toxins secreted by sponges provide a competitive advantage.
Answer:
Nucleus, chromosome, gene
Explanation:
The nucleus is the part of the cell where chromosomes are found. A human cell has 42 chromosomes. The chromosome have genes on them (made up of DNA strands – the strands are made of nucleotides). A gene is a sequence of nucleotides of the DNA that code for a functional protein.
Hydrolysis is the reaction that stems from the breakdown of large molecules by the enzymatic addition of water. Hydrolysis is step leading to the degradation of the substa…nce. It is a chemical reaction in which a molecule of water is added to a substance.
D is the correct answer because the capital letter represents the dominant allele. All of the plants are pure bred. The first pea plant is short (tt) with purple flowers (PP). The second is tall (TT) with white flowers (pp). Therefore the cross is ttPP x TTpp
The characteristics that suit a species for survival are transmitted from one generation to the next through genes which are the units of hereditary information.
<h3>What is a Gene?</h3>
This is referred to as the basic functional unit of heredity and is composed of DNA which are passed from the parent to the offspring.
This is done through the process which is known as meiosis in which four unique daughter cells are produced.
This is therefore how characteristics that suit a species for survival are transmitted from one generation to the next through the gene and is the most appropriate choice.
