Explanation:

While working in a laboratory it is very important to ensure that all safety measures are being followed otherwise it is possible that an accident in the laboratory can lead to harmful effects to a person.

For example, while heating a test tube we should use tongs so that our hand do not burn or feel the heat.

Also, check the apparatus carefully before using them to check if there are any chips or not.

Hence, we can conclude that steps to ensure laboratory safety during the experiment you carried out are as follows.

  • Using test tube tongs to handle the hot test tubes
  • checking the beaker for chips prior to heating on the hot plate
  • turning off the hot plate after use

. What is the role of water in this anabolic process
solniwko [45]
Cellular respiration is also a catabolic process because it breaks the small molecules from digestion into even smaller ones as ATP is created. These are both very important processes, because ATP is what your cells use to produce body heat, move your muscles, and other essential bodily functions.

In a particular family, one parent has Type A blood, the other has Type B. They have four children. One has Type A, one has Type
AlladinOne [14]

Answer:

The correct answer is -

Parental genotypes: AO & BO

Children genotypes: AB, AO, BO, and OO

Explanation:

In the human blood group system, more than two types of alleles are present that lead to the existence of four blood groups in the human population.

Here, A and B alleles are co-dominant while the O allele is recessive to both A and B alleles in the ABO system.

The cross depicting the genotypes of children is

IA IO

IB    IAIB    IBIO

IO   IAIO   IOIO

In this cross, we get the same result as given in the question -

One parent has A and the other has B type blood while the children have all four types of blood groups One has Type A, one has Type B, one has Type AB, and the last has Type O. It is possible only when parents are heterozygous in their genotypes and not expressing codominance.
