A bacterium is infected with an experimentally constructed bacteriophage
dem82 [27]

The complete question is:

a bacterium is infected with an experimentally constructed bacteriophage composed of the T2 phage protein coat and T4 phage DNA. The new phages produced would have

A) T2 protein and T4 DNA

B) T2 protein and T2 DNA

C) a mixture of DNA and proteins of both phages.

D) T4 protein and T4 DNA

E) T4 protein and T2 DNA

A bacterium infected with an experimentally constructed bacteriophage will give new phages with the virus' DNA and the type of proteins that this DNA encodes.

A bacteriophage is a virus that attaches itself to a bacteria and uses it to replicate itself. Viruses have two main parts, a protein coat and their DNA inside it.

  • The experimentally constructed bacteriophage has one type of protein that makes the coat, the T2. This type of protein will allow the virus to attach and infect the bacteria.
  • Once the virus attaches itself to the bacteria, it will introduce its DNA, T4 type, and use the bacteria elements to replicate it and create new phages.
  • As a result, the new phages will have T4 DNA, and the proteins that the virus synthesizes will be the same type as the DNA.

In conclusion, The new phages produced would have D) T4 protein and T4 DNA.

Bezzdna [24]

Answer:

1.Blood pressure in the small capillaries pushes the fluid into a sack called Bowman's capsule. 2. It reabsorbs important nutrients that are in the filtrate. 3.  The Loop of Henle descends from the cortex into the medulla and concentrations of salts in the interstitium increases. 4. Salts leave the filtrate using both passive and active diffusion. 5. Waste products ammonia and urea are transported into the filtrate for excretion, while calcium and sodium continue to be reabsorbed and water leaves the nephron. 6. The filtrate empties into collecting ducts, where it combines with filtrate from other nephrons.

Mendel's F1 generation of pea plants were heterozygous. What does this mean? A. All of the offspring plants would have the reces
mafiozo [28]

Answer:

option D

Explanation:

When an organism is heterozygous for a particular trait, it means the organism has two different allele for that particular trait. An allele is the alternate for of a gene. For example, using Mendel's pea plants, he studied the height trait having the tall and the short allele for this height trait. Thus, this cn be written as (Tt) where T represent the tall allel and t represent the short allele.

C) Can be tested many independent researches is a scientific theory.

A scientific theory is developed when it has been passed through many researches and had gained acceptance too.

D) Both Scientific theory and hypothesis are based on the observations of the natural phenomena.

Firstly, an observation is made based on natural phenomena, which leads to questions, then research or study is carried out to answer these questions leading to the formation of a hypothesis which upon successful  testing forms a theory.

E) Scientific theory is a well-established highly reliable explanation.

It a highly sustained explanation based on facts of nature, that are confirmed via a lot of experiments.
