Answer:

AB, ab, Ab and aB

Explanation:

The zygote has the genotype <em>AaBb </em>because it was formed by the fusion of a sperm cell <em>AB</em> and an egg <em>ab</em>.

During meiosis the diploid <em>AaBb</em> germ cell will reduce its chromosome number by half, producing a total of 4 haploid daughter cells (the gametes, in males the sperm cells) with just one allele per gene. The genes <em>A </em>and <em>B</em> are on different chromosomes, so they assort independently, and 4 types of gametes can therefore be produced: <em>AB, Ab, aB </em>and <em>ab</em>.

Why do living things share fundamental characteristics
Ghella [55]

Answer:

All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.

Life processes are important to carry out daily life activities. They help to produce energy and maintain homeostasis in the body. The life processes help a body survive with the changes in the environment.

Beryllium is one of the elements that scientist can use as a cosmic clock to determine age true or false
wariber [46]

Answer:

False

Explanation:

Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.  Other beryllium alloys are used as structural materials for high-speed aircraft, missiles, spacecraft and communication satellites.  Beryllium is also used in nuclear reactors as a reflector or moderator of neutrons.
