Researchers studying parental care in 20 female robins found that every female robin would place a recently collected worm into

the first open mouth she saw in her nest. It appeared that the sight of an open mouth triggered the female bird's feeding behavior. To test this hypothesis, a robotic baby robin was added to every one of the 20 nests. The robot baby always had its mouth open, and the female robin always fed it first. We can conclude that _________

The correct answer is; the open mouth of a baby robin is seen as a sign stimulus for the female robin (parent), and that the open mouth is the impending cause for her behavior.

Answer:

Capsule

Explanation:

In many bacterial species, an extracellular layer composed of a polysaccharide especially a monosaccharide is produced around the cell wall of the bacteria. This extracellular layer is known as the slime layer or the capsule.

The capsule in bacteria serves many purposes like it protects the bacteria from the destruction by the white blood cell in the host, it enables the bacteria to adhere to the substrates and protect it.

In the plant group called the bryophytes also a capsule structure is present which grows in the sporophytic phase and encloses the spores, therefore, the capsule is considered the sporangium of the bryophytes.

Thus, the capsule is correct.

How is the information stored within the base sequence of DNA used to determine a cell’s properties?
vovikov84 [41]

Answer:

The genetic material of most of the organism is Dexoxy-ribonucleic acid OR DNA which are formed of the monomer unit called nucleotide. Each nucleotide is composed of a 5-C deoxyribose sugar, a phosphate group and 4 types of nitrogenous bases mainly adenine, cytosine, guanine and thymine.

It is the sequence of these nitrogenous bases which determine the fate of a cell as these nitrogenous bases are read by the ribosome in the form of triplets called codons where each codon codes for specific amino acids. These amino acids bind to each other via peptide bonds to form proteins.

Thus, these nitrogenous bases control the important property of the cell.
