Answer:
fern is the producer.
Explanation:
producers are mainly green plants.
Answer:
Signal transduction
Explanation:
A signal molecule binds to a receptor.
A conformational change in the signal-receptor complex activates an enzyme.
Second messenger molecules are released.
Protein kinases are activated.
Target proteins are phosphorylated.can be defined as the process in which a physical or chemical signal is transmitted through a cell as a series of molecular events inform of protein phosphorylation are catalyzed by protein kinase and this ultimately result into a cellular response. However, the protein that is responsible for the detection of stimuli is commonly refers to as receptors or sensor.
Answer:
In biology, a gene is a basic unit of heredity and a sequence of nucleotides in DNA or RNA that encodes the synthesis of a gene product, either RNA or protein. During gene expression, the DNA is first copied into RNA.
Euchromatin is a lightly packed form of chromatin that is enriched in genes, and is often under active transcription. Euchromatin comprises the most active portion of the genome within the cell nucleus. 92% of the human genome is euchromatic.
The genes present in heterochromatin are usually inactive. The genes present in euchromatin are either already active or will be active during growth. Heterochromatin is transcriptionally-inactive. Euchromatin is transcriptionally. (This one here is the difference)
Answer:
<em>The correct option is D) the rate of photosynthesis increases and then levels off.</em>
Explanation:
Photosynthesis can be described as the process by which plants make their own food from carbon dioxide and water by using light energy from the Sun. Oxygen is produced as a by-product of this reaction.
As we increase the intensity of light, the rate of photosynthesis also increases. But after a certain time, the reaction rate will level off as there might be enough food produced or the light energy might have caused the temperature to rise which would have caused the enzymes to get denatured.
<span>A physician may be virtuous (kind, just, and honest) and still not know which actions are known as morally permissible.
There are more ways to define "morally permissible." One is to break the words apart, to define "morally" and then "permissible." However, there is a more holistic way. In Ethics in the First Person, Deni Elliott defines permissibility thusly. Permitted [means] behavior that is within the bounds of the moral system.</span>
