Answer:
A subkingdom of green plants that make up vegetation on earth.
Explanation:
Embryophyte is a major grouping of plants that have enclosed embryo as within a seed. They are sometimes known as land plants.
The density is the relation mass/volume.
Then you can modifiy the density of a material by either affecting the mass or the volume.
If you increase the volumen while keeping the mass constant, the density will decrease (because you are increasing the denominator of the fraction).
Also, you can decrease the mass while keeping the volume constant to decrease the density (because you are decreasing the numerator of the fraction).
Then the answer is decrease the mass or increase the volume, while the other is kept constant.
C. Heat energy is transferred from warmer objects to cooler objects
Answer:
The correct option is b) all genes of all of the individuals in a specific population
Explanation:
In ecological studies, a gene pool can be described as all the genes which organisms of a specific population possess. The higher the number of genes in the gene pool, the higher will the genetic diversity of the population. The more the genetic diversity, the more stable the population will be in the ecosystem. Hence, option B is correct.
Other options, like option D, is not correct because a gene pool refers to all the genes of organisms of a population, not a single individual.
