Answer:
No.
Explanation:
The prime meridian is a longitude of zero on a map. It has nothing to do with space or the atmosphere.
Every day they charted whether upstairs and downstairs were either too cold, cold, warm, too warm, or hot. They tallied their results, learning that the two weeks of using both units; the house was a bit too warm. The month where only the downstairs unit was used, they noted downstairs and upstairs were warm. This did not support their prediction that it would be cold.
They began to wonder how upstairs could still be warm during the daytime when only using the downstairs unit. What is the best possible explanation for upstairs being warm throughout the winter month when they only turned on the downstairs unit?
Answer:
Convection
Explanation:
Hot air rises as it has less particles and more volume. This means that when they heat downstairs, the hot air rises to the top. Then, it cools and sinks because cold air has more particles and less volume. It heats up again from the downstairs unit and the cycle keeps going. This is called convection
Answer:
The volume of warm air expands and rises, warming the whole house through convection.
Explanation:
B. A gamete carries one allele for a gene.
C. A gamete can carry multiple alleles for a trait.
D. Some gametes are dominant and some are recessive.
The principle of segregation given by Gregor Mendel based on his experiments with the pea plants states that alleles of a gene for any trait are segregated during the formation of the gametes. Therefore, a gamete contains only one allele of a gene. When the male and female gamete combines during fertilization, the two alleles (one from each gamete) combine to form the gene.
Hence, the correct answer is 'Option B - A gamete carries one allele for a gene'.
Answer: The correct answer is- B. A gamete carries one allele for a gene.
Gamete ( also called sex cell or reproductive cell) is a haploid cell ( having half number of chromosome as compared to the parent cell) that is produced through a cell division, termed as meiosis in sexually reproducing organisms.
According to Mendel's second law of inheritance that is law of segregation,
For every trait/ characteristic of an individual, there are two variant forms of a gene (called alleles) that are separated from one another so that every gamete possesses one allele. This law is also known as law of purity of gametes.
Thus, option B) is the right answer.
Answer:
decline: decrease
Explanation:
Transpiration is the loss of water from stomata by the process of evaporation. It occurs by the process of diffusion and is driven by the concentration gradient of water vapor. The higher the concentration gradient between air and leaf cells, the higher is the rate of diffusion of water.
On a sunny day, the rate of transpiration is higher since air is less humid and the concentration of water inside the leaf is higher. On the other hand, the air is more humid on a rainy day. The increased water vapor content of air reduces the concentration gradient between air and leaf cells. The reduced concentration gradient decreases the rate of transpiration.
High energy produced during the metabolism of reactant to product. Due to the large free energy of activation, the speeds of uncatalyzed biochemical reactions are often exceedingly slow. Enzymes lower this energy of activation so that more molecules have adequate energy to carry into the transition state to speed up the rate of reaction.
