Over time all of the bacteria should become extinct. B) In any population, variation exists. Some bacteria are resistant to antibiotics.

Which of the three experiments gave evidence that protein was not the genetic material?

Answers

I believe it was hershey and chase

Final answer:

Chase and Hershey conducted experiments in 1952, using bacteriophages that revealed DNA, not protein, was the genetic material.

Explanation:

The experiments that revealed protein was not the genetic material were conducted by Martha Chase and Alfred Hershey in 1952. They were studying a bacteriophage, a virus that infects bacteria, which has two main structures: a protein coat known as the capsid, and a nucleic acid core that contains either DNA or RNA.

Hershey and Chase used radioactive markers to label the protein coat and DNA of the bacteriophage, respectively. Through their experiments, Hershey and Chase discovered that only the DNA entered the host bacteria upon bacteriophage infection, suggesting that DNA, not protein, is the genetic material. Their work was instrumental in establishing DNA as the molecule responsible for heredity.

What is punnet square?

A cross or breeding experiment's genotypes can be predicted using the Punnett square, a diagram with squares. This square bears Reginald C. Punnett's name, who created this invention in 1905.

Two heterozygous plant crosses will result:

  T         T                        Y         y

T   TT     TT                   y   Yy     yy

t    Tt       Tt                   y   Yy      yy

The ratio of TT =   1/2     The ratio of Yy =  1/2

The total ratio of TTYy is 1/2 x 1/2 = 1/4 = 25%.

Therefore, 25% of the progeny should carry the TTYy allele combination, according to expectations. The offspring produced is heterozygous.

#SPJ12

Answer:

1/4 in fraction and 25% in percentage

Explanation:

When Mendel crossed purebred purple flowering plants (PP) with purebred white flowering plants (pp), what were the flower colors of the resulting offspring? 25 percent white and 75 percent purple 50 percent white and 50 percent purple 100 percent purple 100 percent white

Answers

The answer is 100 percent purple

Let P be dominant allele for purple flowers and p recessive allele for white flowers. So purebred purple flower has two P alleles and its genotype is PP and purebread white flower has two p alleles and its genotype is pp. Since P is dominant over p, when found together like in heterozygous plants (Pp), the flowers will express dominant allele and will be purple.
So, a cross between purebred purple flowering plants (PP) with purebred white flowering plants (pp) will have 100% of the offspring with genotype Pp and purple flower color.

Parents:               PP      x       pp
Offspring:        Pp     Pp      Pp    Pp

When Mendel crossed purebred purple flowering plants (PP) with purebredwhite flowering plants (pp), the flower colors of the resulting offspring is: 100 percent purple.

WHAT IS MENDEL CROSS:

  • Gregor Mendel, who is referred to as the FATHER OF GENETICS, crossed pea plants using several of their characters.

  • He crossed purebred purple flowering plants (PP) with purebred white flowering plants (pp) to obtain offsprings that were all purple flowered (Pp).

Therefore, it can be said that when Mendel crossed purebred purple flowering plants (PP) with purebred white flowering plants (pp), the flower colors of the resulting offspring is: 100 percent purple.

in humans, the allele for hemophilia, h, is recessive. which is true of a woman with the genotype xhxh? a. the woman and all of her children are hemophiliacs. b. all of her sons will inherit the allele for hemophilia. c. she is a carrier of hemophilia but does not have the condition.

Answers

The answer is b. all of her sons will inherit the allele for hemophilia.

Hemophilia is X-linked recessive disorder. It is known that there are two X chromosomes (one from a mother and one from a father) in females and one X chromosome (from the mother) and one Y chromosomes (from the father) in males. In females, X-linked recessive disorder has the same pattern of inheritance as an autosomal recessive disorder.
So, if xh is recessive and xH is dominant allele, a mother which has xhxh genotype has the condition (so, c is not the right answer). Further, if a father has no condition, thus his genotype is xHy, their daughters will be carriers but without the condition (so, the choice a could be right only if we know that the father has hemophilia too (xhy). Therefore, since the mother (xhxh) will give her x chromosome to her sons, they will all inherit the allele for hemophilia, and choice b. is the right answer.

She is a carrier of hemophilia but does not have the condition

A tiny rocky island in the South Pacific is home to a very small food chain. Coconut palms grow on the island and drop coconuts. The coconuts are eaten by coconut crabs. The coconut crabs are then eaten by seals. According to an ecological energy pyramid, the seals would receive about ___________ of the energy that the crabs receive.

Answers

Answer:

is 1%

Explanation:

Answer:

The seals would receive about 1% the amount of energy as the crabs.

Explanation:

The seals would receive about 1% the amount of energy as the crabs. The 10% rule says that as you move through an energy pyramid, the available energy decreases by about 90%, leaving 10% available energy for the next trophic level. Since the energy moved through two tropics levels, there is only about 1% available: 100% to 10% to 1%.
