Answer:
C. metals
Explanation:
Elements in the periodic table are grouped into metal and non-metals depending on their characteristics. Metals usually possess the following characteristics:
- High melting and boiling point
- Brittle i.e. ability to break
- lustre i.e. ability to shine when polished.
- Good conductor of heat and electricity
Based on this above characteristics, element Q in this question is a METAL because it posseses the same qualities that a metal does.
Answer:
multicellular.
Explanation:
Organisms exhibit various levels of organization of the body. It includes cellular level, tissue level, organ level, organ system level of organization. The unicellular organisms have single cells as their bodies and therefore do not have the genes that regulate the various parts of the body rather than the individual cells. Prokaryotic are unicellular organisms only and do not have multiple cells in their bodies. Therefore, the mentioned genes are the regulatory genes that coordinate the functioning of various parts of the body of a multicellular organism. For instance, the genes involved in regulation of blood glucose levels.
Answer:
Oxygen liberated during photosynthesis comes from the splitting or hydrolysis of water in the green plants. Cornelius van Niel experimentally proved for the first time that the oxygen liberated during photosynthesis comes from water and not from carbon dioxide.
The wrinkled pea will have two recessive alleles on the locus.
Explanation:
Two forms of same gene are called alleles of that gene.
The allele that expresses itself under heterozygous condition is called the Dominant allele.
The recessive allele can express itself only if they are under homozygous combination i.e. both the alleles on homologous chromosome are recessive.
Here wrinkled pea is a recessive trait and if it is expressed in the phenotype then the genotype of the plant must be homozygous for the recessive allele.
Answer:<u><em>When water freezes, it contracts, decreasing the water level in a lake. Water in a lake freezes from the bottom up, killing most aquatic organisms. When water in a lake freezes, it floats, providing insulation for organisms below.</em></u>
