<h3><u>Answer;</u></h3>
He crossed two pure breeds
<h3><u>Explanation;</u></h3>
- <em><u>F1 or the first filial generation is the first generation of offspring produced by crossing a set of parents to help show what genes will be inherited from crossing pea plants. Therefore, the F1 generation consist of or offspring from the parents.</u></em>
- <em><u>Mendel performed a true breeding cross, meaning he crossed one homozygous recessive for a trait and one homozygous dominant for the trait. This gave rise to the heterozygous dominant offspring. </u></em>
Answer:
Antibiotics are strong medicines that treat bacterial infections.
Answer: here´s why
Explanation: Underneath the frozen upper layer, the water remains in its liquid form and does not freeze. Also, oxygen is trapped beneath the layer of ice. As a result, fish and other aquatic animals find it possible to live comfortably in the frozen lakes and ponds. If water is heated, its volume gradually decreases.
Answer:
Enzymes function best at specific pH and temperatures.
Explanation:
An enzyme can be defined as a biological catalyst that typically lowers the activation energy of a biological reaction. When the activation energy of a reaction is low, the rate of the reaction would be faster. Therefore, an enzyme speeds or catalyzes the rate of a reaction by lowering its activation energy.
Also, if the conditions are not optimal for an enzyme, it limits the ability of an enzyme to bind or be joined with its substrates.
Hence, the correct statement about enzymes is that enzymes function best at specific pH and temperatures. An increase in temperature increases or speeds up the rate of a reaction while low temperature limits or reduces the rate of a reaction. The optimal temperature for enzymes in the human body is around 37 degrees celsius.
Answer: This mode of inheritance is known as Incomplete Dominance
Explanation:
Incomplete dominance occurs when a cross between two contrasting alleles (such as Type A and B) produces a heterozygous phenotype different from the two parents.
Thus, both Type A and B are dominant over Type O blood
