Answer 1

Answer:

1/4 chance.

Explanation:

I used a punnet square to calculate the possibility and it seems to be a one in four chance.

Answer 2

Answers

G is your answer. I took the test.

Bacteriophage and E.coli are alike in the sense that they both lack membrane-bound organelles.

What are bacteriophage?

Viruses that infect bacteria are called bacteriophage. The words bacteriophage mean "bacteria eater". Bacteriophages take over the machinery of host cells to produce copies of themselves and then destroy the host cell in the process.

Bacteriophages are composed of a supercoiled nucleic acid which is surrounded by a protein capsid.

A bacteriophage adheres to the surface the susceptible bacteria and injects its genetic material. This way they occupy the genetic machinery of the host and produce several copies of their own nucleic acid and also the protein capsid to surround it.

The result is the lysis of bacterial cell and release of thousands of bacteriophage viruses which are capable of infecting more bacteria in the same manner.

Bacteriophage are acellular structures lacking any membrane bound cell organelles. E.coli is a kind of prokaryotic bacteria which also lack membrane bound organelles.

Therefore, the correct option is D.

Bromothymol blue (BTB) is a chemical that can be used as an indicator of the pH of a solution. Because CO2 produces an acid in water, BTB can indirectly measure how much CO2 is present in a solution. When placed in solutions with neutral pH (little CO2), the solution appears green. In solutions with low pH (high CO2), the solution appears yellow.

A teacher performed a demonstration to investigate how photosynthesis and respiration cycle carbon and oxygen. She placed a few drops of BTB in a test tube containing distilled water. Because distilled water has a neutral pH, the solution appeared green. The teacher used a straw to blow into the solution, and the solution turned yellow. She then placed an aquatic plant into the test tube, covered it to keep it air tight, and placed it under a light for 24 hours.

What color would the solution in the test tube be after being in the light, and what would it be if it were then placed in the dark for 24 hours, and why?
A
Green after being placed in the light because the plant would remove CO2 by photosynthesis; yellow after being placed in the dark because the plant would release CO2 by respiration.

B
Yellow after being placed in the light because the plant would release CO2 by photosynthesis; green after being placed in the dark because the plant could not photosynthesize in the dark.

C
Green after being placed in the light because the plant would remove CO2 by photosynthesis; green after being placed in the dark because no CO2 would enter the tube since it is air tight.

D
Yellow after being placed in the light because the plant would release CO2 by photosynthesis; yellow after being placed in the dark because no CO2 could leave the tube since it is air tight.

Answers

Answer:

A. Green after being placed in the light because the plant would remove CO2 by photosynthesis; yellow after being placed in the dark because the plant would release CO2 by respiration.

Explanation:

According to this question, Bromothymol blue (BTB) is a chemical that can be used as an indicator of the pH of a solution. The presence or absence of CO2 in a solution decreases or increases the pH of the solution respectively.

- BTB appears green in a neutral pH i.e. little CO2

- BTB turns yellow in a low pH i.e. high CO2

Plants, in the presence of light, will perform photosynthesis and use CO3 as a reactant while in the dark, will perform cellular respiration and release CO2 as a waste product. Hence, in this case where an aquatic plant was placed into a test tube and covered it to keep it air tight.

- When placed under light for 24 hours, the aquatic plant will undergo photosynthesis and remove CO2 from the solution to make the solution appear GREEN due to neutral pH.

- When placed in the dark for 24 hours, the aquatic plant will undergo cellular respiration and release CO2 into the solution making the solution appear YELLOW due to low pH.

A partial DNA sequence for normal hemoglobin and a partial DNA sequence for sickle-cell anemia are shown below. G-G-A-C-T-T-C-T-T Normal hemoglobin G-G-A-C-A-T-C-T-T Sickle-cell anemia Based on the DNA sequences, sickle-cell anemia is caused by A. a sex-linked trait. B. a dominant nucleotide. C. a mutation in the genetic code. D. an incomplete separation of chromosomes.

Answers

Answer:

C. a mutation in the genetic code.

Explanation:

A mutation refers to any change or alteration to the nucleotide sequence of a gene caused by mutagen or mistakes during replication. Depending on the manner of occurrence, mutation can be of different types. In this question, partial DNA sequence for normal hemoglobin is given as: G-G-A-C-T-T-C-T-T while the partial DNA sequence for sickle cell anaemia is given as: G-G-A-C-A-T-C-T-T.

From careful observation of the two two DNA sequences above, it can be realized that a SUBSTITUTION MUTATION from T to A has occurred in the sequence of sickle cell. Note that substitution mutation is the replacement of one base by another in a sequence.

Which of the following has not sped up the erosion of wetlands in coastal Louisiana?
A. dredging of thousands of kilometers of canals throughout the wetlands
B. the increase in acidity of the rainwater in the southeastern United States
c. the loss of barrier islands the cost of Louisiana
D. the 2010 Deepwater Horizon well blowout

Answers

Answer: B. the increase in acidity of the rainwater in the southeastern United States

Explanation:

The dredging of thousands of canals throughout the wetlands for easier navigation has sped up the erosion of Louisiana wetlands so option A is false.

The loss of barrier islands on the coast of Louisiana as a result of rising sea levels has also sped up the erosion of the wetlands as they are now more exposed to open water so option C is wrong as well.

The 2010 Deepwater Horizon disaster spilled so much oil that adversely affected the wetlands leading to their erosion so option D is wrong as well.

Option B is therefore right.

Brainliest please :)

Help please ! Thanks

Answers

Answer:

75%

Explanation:

The allele for purple flowers (capital P) is dominant.

The allele for white flowers (lowercase p) is recessive.

If one allele is capital P, it doesn’t matter if the other allele is another capital P or a lower case p, the capital P will dominate and purple flowers will show up.

The Punnett Square shows:

PP, Pp, Pp, and pp

• 3 of the offspring have at least one dominant and capital P, so purple flowers show up.

• 1 of the offspring has two lowercase and recessive alleles (p), so white flowers show up.

3/4 or 75% of the offspring will have purple flowers.

Hey There! _____________________________________ Answer:

[tex]\huge\boxed{Option A}[/tex]

_____________________________________ PEA PLANT:

Pea plant has purple color flowers dominant over white color flowers.

Purple flower dominant allele is P

White Flower recessive allele is p

We would get White flower pea plant only when the recessive allele is in HOMO.ZYGOUS condition

_________________________________________________________

CONDITIONS:

Hom.ozygous Dominant Alleles: PP (Purple Flower)

Heter.ozygous Dominant Alleles: Pp Purple Flower)

Hom.ozygous Recessive Alleles: pp (White Flower)

____________________________________ CROSS:

Whenever we cross Heterozygous Dominant(Pp) purple flower with another Heterozygous dominant (Pp purple flower), we get 75% of the flowers PHENOTIPICALLY(physical appearance) white flowered, and 25 white flowered Because as you can see in the picture,

The P1 is Pp

The P2 is Pp

When we cross them,

It has 4 offsprings,

PP Hom.ozygous Purple flower  

Pp Heterozygous Purple flower

Pp Heterozygous Purple flower

pp Hom.ozygous white flower

Thus the answer is 75% as there are phynotypically 3 purple flowers present
