Answer:
two carbon atom and six hydrogen atoms join together to form ethane.
Explanation:
Which scientist developed the idea that microorganisms can cause diseases? Paul Ehrlich
The main purpose of seeds is to carry out reproduction so that the plants can perpetuate themselves. After pollination and Fertilization the seed formed has the capacity to germinate into an adult plant over time. It has all the necessary nutrients and food sources required for a plant to germinate and are also modified for different species to allow for further dispersal so the plant can spread more easily to better growth conditions.
Answer:
C. All plankton are closely related to plants.
Explanation:
Plankton are organisms found in water that exist in a drifting state. They are too small or weak to swim on their own, so they let the current or tide carry them. They are usually microscopic but include larger species as well, such as some crustaceans and jellyfish.
Phytoplankton are autothrophic plankton. This means that they produce their own food. They are primary producers and closely related to plants.
Zooplankton are heterotrophic plankton, which means that they feed on other organisms. They are animals and aren't closely related to plants.
Nekton are organisms found in water that swim actively.
Based on this information, we can conclude that statement C is the only incorrect statement.
Answer:
Increase in transcription
Explanation:
Transcription is the process of forming RNA from DNA. It can be controlled by many factors like a repressor. Repressor can bind to the operator region of the promoter and hinder the movement of RNA Polymerase enzyme, halting the process.
Here, it is given that the repressor needs to first bind to an effector molecule X. Once it binds to X, it is activated and then it can bind to operator of gene A to inhibit its transcription. If the X binding domain on repressor is mutated it wont be able to bind to X. Thus it wont get activated and wont be able to attach to operator region to inhibit transcription. Hence, transcription process will keep going on uncontrolled.
