Explanation:

The Hershey–Chase experiments were a series of experiments conducted in 1952 by Alfred Hershey and Martha Chase that helped to confirm that DNA is genetic material. Hershey and Chase and subsequent discoveries all served to prove that DNA is the hereditary material.

Genetic information is carried in the linear sequence of nucleotides in DNA. Each molecule of DNA is a double helix formed from two complementary strands of nucleotides held together by hydrogen bonds between G-C and A-T base pairs. In eucaryotes, DNA is contained in the cell nucleus.

Answer:

Plant and animal cells are similar because both are eukaryotic. Every plant and animal cell has a cell membrane and cytoplasm. In addition, nearly all plant and animal cells have a nucleus.

Explanation:

Its answer is ribosome

Answer:

B protista

Explanation:

The cell is unicellular, so it can not be an animal, which are all multicellular.

It contains a nucleus, which means it cannot be prokaryotic (it cannot be bacteria)

The cell is autotrophic, which means it cannot be a fungus, which are heterotrophs

Therefore, the organism must be a protist, so the answer is B, protista.

Answer:

An analogy for the cell wall is that thecell wall is like an outer wall along a castle (enclosed compound). The cell wall is a rigid outer barrier.

Answer:

It might not work as efficiently because the conditions are different

Explanation:

The stomach is highly acidic compared to the small intestine. That means the pH is higher in the small intestine. Stomach enzymes are adapted to work at low pH, but might not work at a higher pH as in the small intestine. They might not be able to efficiently catalyze reactions in the small intestine.

Answer:

During freezing, water molecules lose energy and do not vibrate or move around as vigorously. This allows more stable hydrogen-bonds to form between water molecules, as there is less energy to break the bonds...Thus water expands as it freezes, and ice floats atop water.

Answer:

Kettlewell thought that if natural selection caused the change in the moth population, the following must be true: Heavily polluted forests will have mostly dark peppered moths. Clean forests will have mostly light peppered moths. Dark moths resting on light trees are more likely than light moths to be eaten by birds.

Dr. Kettlewall predicted that clean forests would have light-colored moths and polluted forests would have dark-colored moths. This is an example of natural selection.

Natural selection is a phenomenon in which the fittest individual is chosen by nature. The animal can live and reproduce in that particular environment. An example is the peppered moth population.

The light-colored moths were found on the light-coloured bark, but their population started to decline after the pollution. In the polluted environment, they were easily chosen by predators. So only dark moths survived because they blended in with the polluted environment.

Following the end of the pollution, light colored moth increased again. Predators had a difficult time identifying the light moth because it blended in with the unpolluted environment. Hence, their population increases in unpolluted areas.

Hence, Dr. Kettlewall predicted that a clean forest would have a light-colored moth and a polluted forest would have a dark-colored moth.

Answer:Three general classes of RNA molecules are involved in expressing the genes encoded within a cell's DNA. Messenger RNA (mRNA) molecules carry the coding sequences for protein synthesis and are called transcripts; ribosomal RNA (rRNA) molecules form the core of a cell's ribosomes (the structures in which protein synthesis takes place); and transfer RNA (tRNA) molecules carry amino acids to the ribosomes during protein synthesis. In eukaryotic cells, each class of RNA has its own polymerase, whereas in prokaryotic cells, a single RNA polymerase synthesizes the different class of RNA. Other types of RNA also exist but are not as well understood, although they appear to play regulatory roles in gene expression and also be involved in protection against invading viruses.

Because it has a cell wall

Answer:

The condition is called "Spinal Bifida", caused by lack of vitamin B12 which helps regenerate the active form of folate.

Explanation:

Because Lori is a vegan, her vitamin B12 intake which comes from animal products such as meat, is not enough. She has to take supplements to make up for the lack of it in her diet.

As stated in the question, this lack of vitamin B12 causes her child to have a defect in his spinal cord called Spinal Bifida that defines a spinal cord or spine that has not fully developed. The vitamin B12 is necessary for regenerating the active form of folate.
