Explanation:
Only 10% of calories will be transfered to the next higher level.
5000 * 0.1 = 500.
500 calories will transfer to the secondary consumers.
The object's mass. Weight would be how gravity affected it, size is how large it is, density is how tightly the molecules are to each other. Mass is how much matter is in the object.
Answer:
Metamorphic rocks are almost always harder than sedimentary rocks. They are generally as hard and sometimes harder than igneous rocks. They form the roots of many mountain chains and are exposed to the surface after the softer outer layers of rocks are eroded away.
Because their mineral grains grew together tightly during metamorphism, they're generally strong rocks.
Answer:
The law of independent assortment states that the different genes get separated independently of each other and gets assorted into gametes to produce different combination of genes.
It was formulates by famous scientist G. Mendel based on his work on peas.
For example, in a traditional dihybrid cross of true breeding round and yellow seed plant with wrinkled and green seed plant, F2 generation show four different combinations of phenotype:
- round and yellow
- round and green
- wrinkled and yellow
- wrinkled and green
It shows that genes for round and yellow were independently inherited and genes for wrinkled and green were independently inherited. Else, new combinations could not be observed.
Homologous recombination is an event that takes place in prophase I during meiosis. The genetic material is exchanged between the non-sister chromtids of homologous chromosomes. It adds into the genetic variation within a population by producing more combination of genes in the gametes.
It does not violate the law of independent assortment as the genes were independently assorted. It only helps in producing more combinations of genes.
Answer:
46 chromosomes
92 Chromatids
One DNA molecule
Explanation:
The interphase part of the cell cycle is divided into 3 sub-phases namely; G1 phase, S-phase and G2-phase
G2-Phase occurs when the cell grows more to make more proteins and organelles. This also when the cell reorganize its contents in preparation for mitosis. The number of chromosomes will therefore, remain the same but the DNA molecule will be one in preparation for mitosis where it can then divide into two
