what is the values of pOH 0.020M HNO3

Answers

Answer 1

Answer:

pOH is 12.3

Explanation:

let's first get the pH of nitric acid:

[tex]{ \sf{pH = - log[H {}^{ + } ]}}[/tex]

but:

[H†] = 0.020 M

therefore:

[tex]{ \sf{pH = - log(0.020) }} \\ { \sf{pH = 1.7}}[/tex]

but, pOH = 14 - pH

[tex]{ \sf{pOH = 14 - 1.7}} \\ { \sf{pOH = 12.3}}[/tex]

Why do i only have one Dimple on my left cheek?

Answers

Answer:

Some people may have only one dimple, but not on their cheek. On their chin. This is called a cleft chin. This is not hereditary but is a result of the incomplete merging of the left and right halves of the lower jaw during embryological development.

Explanation:

Many people do not have exactly symmetrical faces. One side might have a slightly different bone structure, for instance. The flesh or fat cells might distribute differently across the cheeks and result in only one dimple.

What does it mean if the allele frequency in a population consistently changes?
A. The population is stagnant.
B. The amount of alleles available is growing.
C. The amount of alleles available is shrinking.
D. The population is evolving.

Answers

Answer:

d

Explanation:

the population is evolving

Allele frequency is the probability of the gene in a particular population. The consistently changing allele frequency in a population depicts the process of evolution. Thus, option D is correct.

What is evolution?

Evolution is the modification in the transitional or the expansion of the inherited characters passed from the parent to the offspring and successive generations over time through reproductive methods.

The allele or the gene frequency defines the evolutionary pattern as the alleles carry and express the characteristics that were passed. Due to environmental changes, the alleles can get modified for better adaptation.

This adaptation and natural selection allow the organism to evolve from the pre-existing species to adapt and with better traits that enable their survival.

Therefore, option D. the changing frequency depicts the evolving population.

What is the function of DNA polymerase?
O DNA polymerase joins individual nucleotides together to form the new complementary strands of DNA.
O DNA polymerase separates nucleotides on strands of during DNA replication
O DNA polymerase is an enzyme that works to transport DNA from the nucleus to the cytoplasm.
O DNA polymerase repairs one old single strand of DNA that came back together after replication.

Answers

Answer:

Smh. This is kinda late, but hope this helps.

Explanation:

The enzyme DNA polymerase catalyzes the formation of sugar phosphate units along the side of the "ladder". The sugar phosphate units connect one base pair/rung on the ladder to the next one.

Therefore our answer is :

A) DNA polymerase joins individual nucleotides together to form a new complementary strands of DNA. :)

The function of DNA polymerase joins individual nucleotides together to form the new complementary strands of DNA. The correct option is the first one.

What is the function of DNA polymerase?

DNA polymerase is an enzyme responsible for catalyzing the synthesis of new DNA strands during DNA replication.

It adds individual nucleotides to the growing DNA strand, following the complementary base pairing rules (A with T, and C with G). This process ensures accurate copying of the genetic information from the template DNA strand to the newly synthesized strand. DNA polymerase plays a central role in DNA replication, which is the process by which cells make identical copies of their DNA during cell division.

Answers

The answer is B I did the question and I got this wrong I choose A but it’s B

Autotrops are the organisms that can prepare their own food by process called photosynthesis. True bacteria and some archaebacterias are the one performing photosynthesis like plants.

What are archaebacteria?

Archaebacteria are a group of microorganisms evolved separately from the bacteria and blue-green algae.

Archaebacteria can also survive in extreme environment. Examples include Halobacterium, Pyrolobus, etc.

Both archaebacteria and bacteria are able to photosynthesize their food.
