igomit [66]

Answer:

The flowchart is not seen in your question. The labeling cannot be done without seeing the flowchart.

Here are the processes of bacterial transformation:

Explanation:

Bacterial transformation is defined as the change in the properties of bacteria which is caused by the introduction of foreign and naked DNA.

DNA is an hereditary material in organisms that contains their genetic information.

Here are the processes of bacterial transformation:

Step 1: Donor cell forms a Donor cell lyses

Step 2: Donor cell homologous binds to a receptor site on the recipient cell.

Step 3: One strand of donor cell DNA is degraded, and transformed DNA Pairs with homologous region on recipient cell.

Step 4: Finally, recombines with recipient cell chromosome

Given the parents AABBCc × AabbCc, assume simple dominance for each trait and independent assortment. What proportion of the pro
Anit [1.1K]

Answer:

3/4

Explanation:

If we assume simple dominance and independent assortment for each trait, we can use Mendel's Law of Segregation to predict the phenotypic proportions in the offspring of the parental cross AABBCc x AabbCc.

<h3><u>Gene A</u></h3>

AA x Aa

  • F1 genotypes: 1/2 AA, 1/2 Aa
  • F1 phenotypes: all A
<h3 /><h3><u>Gene B</u></h3>

BB x bb

  • F1 genotypes: 1 Bb
  • F1 phenotypes: all B
<h3 /><h3><u>Gene C</u></h3>

Cc x Cc

  • F1 genotypes:  1/4 CC, 2/4 Cc, 1/4 cc
  • F1 phenotypes: 3/4 C, 1/4 cc

We want to know the proportion of progeny with all dominant phenotype (A_B_C_). Since the genes are independent, we can multiply the probabilities of each gene to obtain the overall probability of having a ABC progeny:

<h3>1 A_ x 1 B_ x 3/4 C_ = 3/4 A_B_C_</h3>

What is the atom of the element boron?
Agata [3.3K]

The atomic number is 5. The atomic number gives the number of protons. Protons which have a positive charge are balanced by an equal number of electrons in a neutral atom.  Boron number 5 has five protons and therefore as a neutral atom also has five electrons. Boron atomic number 5 has five electrons in its ground state.  Commonly Boron will lose 3 electrons leaving 2 electrons in its most common ionic form.
