In order to use a Punnett, square we must know the ___________ of an individual
egoroff_w [7]
  <span>The genotype is required for you to use a punnet square. In the construction of a punnet's square, the genotypes of both parents are required. In the three by three square, the first column shows the genetic representation of one parent and the first row shows the genotype of the other parent. The two are combined, and they yield a genetic combination of both parents, giving all the possible outcomes of the offspring's genotypes. Using the punnet's square, you can be able to identify the percentage of the offspring that will be heterozygous or homozygous.</span>

What is a “spill-over” infection
Sav [38]

Explanation:

Spillover infection, also known as pathogen spillover and spillover event, occurs when a reservoir population with a high pathogen prevalence comes into contact with a novel host population.

Which of the following organelles is primarily responsible for the formation of the cell's lysosomes
Marizza181 [45]
<h3><u>Answer;</u></h3>

Golgi apparatus or Golgi complex or Golgi bodies

<h3><u>Explanation;</u></h3>
  • <u><em>Golgi apparatus are also called Golgi bodies or Golgi complex. They are complex vesicles and folded membrane within the cytoplasm of eukaryotic cells.</em></u>
  • <em><u>Golgi apparatus are important in the secretion and intracellular transport roles. A major function is the modifying, sorting and packaging of proteins for secretion. T</u></em><em><u>hey are also involved in the transport of lipids around the cell, and the creation of lysosomes.</u></em>
  • Therefore, <u><em>Golgi apparatus are the organelles responsible for the formation of lysosomes, which are organelles that destroy old and worn out cellular organelles. </em></u>

Phosphorus is required to synthesize the deoxyribonucleoside triphosphates used in DNA replication. A geneticist grows some E. c
Harlamova29_29 [7]

Answer:

<h2> After one round: one strand of DNA  will contain radioactive 3232P, while the other strand  will not contain any radioactive phosphate. </h2><h2> After two rounds:  here 50%  of DNA will have 3232P in both strands, while 50% will contain 3232P in one strand and nonradioactive in the other strand. </h2>

 

Explanation:

1. In the initial sample which is immediately removed after addition of radioactive isotope of phosphorus ( 3232P), hence there is  no incorporation of 3232P into the DNA because replication in the medium containing 3232P has not yet occurred.  

2. After one round of replication in  radioactive isotope of phosphorus ( 3232P) containing  medium, here  only one newly synthesized strand of DNA molecule will contain 3232P, while the other strand  will not contain any  radioactive isotope of phosphorus ( 3232P),  because DNA replication occurs in semi-conservative way.

3. After two rounds of replication in medium which contains radioactive isotope of phosphorus ( 3232P), here 50% of the DNA molecules will have  radioactive isotope 3232P in both strands, while the rest 50% will contain 3232P in only one strand and nonradioactive phosphorous in the other strand.
