Answer: B. all the nitrogen obtained by animals come from plants.

Explanation:

Animals are unable to use inorganic bacteria until plants absorb it and then animals get it from the plants so in effect, all the nitrogen obtained by animals comes from plants.

Plants absorb nitrogen in the form of Nitrates which were fixed by bacteria from Nitrites which were further fixed from Ammonium which was fixed from atmospheric Nitrogen all by bacteria.

Several students were having a discussion about the role of chromosomes in inheriting traits.
serious [3.7K]

Answer:

Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.  

Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.

Explanation:

Chromosomes are the structures found in the nucleus of a cell. They are made from DNA, containing hereditary information in the form of genes that control how an organism will look and behave.  - this is true. Prior to cell division, DNA molecules are organized into large structures called chromosomes. Specific regions of a DNA molecule are called genes. These dictate specific proteins which control our traits.

Genes contain thousands of chromosomes that carry specific information about building proteins for a particular trait.  - this is false - genes are segments of DNA that control specific traits by dictating the structure and functions of proteins. Chromosomes contain thousands of genes

Chromosomes are small sections of DNA that contain specific information about a trait to build proteins that people inherit. The thousands of different chromosomes passed from the parents allow for humans to look uniquely different. - this is false - chromosomes are large structures, genes are the relatively small sections of DNA. Humans have 23 pairs of chromosomes, not thousands.

Chromosomes come in homologous pairs (one from each parent) that each contain thousands of genes, determining traits expressed in the offspring.  - this is true. In diploid organisms, like humans, have two copies of each chromosome. These chromosomes contain slightly different versions of genes, which make us unique.

In what way are the structures of dna and protein similar?
Verizon [17]
They are similar in three main ways 1.Both DNA and proteins are polymers. 2. Both are made from smaller subunits joined together. DNA is made of subunits called nucleotides joined together and protein is made up subunits called amino acids joined together. 3. In both of them, these subunits or monomers are linked together by covalent bonds. Nucleotides are a combination of a nitrogen - rich base that is either adenine, guanine, cytosine or thymine, together with a phosphate group and a sugar.

A person will most likely develop aphasia as a result of damage to which parts of the brain?
Anna11 [10]

Answer:

The correct answer is Broca's area or Wernicke's area.

Explanation:

Aphasia refers to a language disorder, which arises due to the destruction of the parts of the brain, which are accountable for language. Aphasia generally causes due to the destruction of Wernicke's area or Broca's area. For the majority of the individuals, these are the sections of the brain's left hemisphere.  

The condition known as aphasia generally takes place suddenly, usually as the outcome of a head injury or stroke, however, it can also arise gradually, in the individuals suffering from a brain tumor. The disorder hampers both the comprehension and expression of language and at the same time the tendency to read and write.
