Answer:

B) a signal-recognition particle that brings ribosomes to a receptor protein in the ER membrane.

Explanation:

Each synthesized protein has to be targeted to the specific location and transported to that location. There are two possible ways for that transport: post-translational transport or co-translational transport.

• Co-translational transport occurs during the process of translation, and proteins transported this way are proteins bound for organelles in the endomembrane system (such as the ER, Golgi apparatus, and lysosome), plasma membrane proteins or proteins for the exterior of the cell. They have an amino sequence called a signal peptide which sends them to ER first.

• Proteins that do not have a signal peptide stay in the cytosol so, their transport is after the translation (post-translational).

What is the expected functional consequence of movement of a transposable element within the genome?
ki77a [65]

All of the listed responses are correct regarding the functional consequence of the movement of a transposable element within the genome.

  • Increased production of a protein
  • Decreased production of a protein
  • Abnormal transcription of a gene

A gene is the fundamental physical and purposeful unit of heredity. Some genes act as instructions to make molecules referred to as proteins. but, many genes do now not code for proteins.

Our genes incorporate instructions that inform your cells to make molecules referred to as proteins. Every gene includes commands that determine your functions, together with eye color, hair shade and height.

1) B
    (I'm not so sure of this one) All of the other options have a steady impact on population regardless of the density of organisms except competition

2) D
    Increased carbon dioxide levels would not hinder plant growth, and tsunamis aren't really linked to carbon dioxide levels. Increased carbon dioxide is unlikely to lower the air temperature so only D is left.

3) A

4) Three properties of water that allow it to sustain life are that it is adhesive, it is a good solvent, and cohesion. Adhesion is important in situations such as water travelling up xylem tubes in plants so that the water is not pulled down by gravity and can reach parts of the plant that need water. Cohesion allows the water being pulled up the xylem to stay together and for water molecules to be pulled when a neighbouring one is moved. Water being a good solvent allows inorganic minerals to be taken with water through vascular tissue, such as in the previous example.

Urgent please help!!!!!
antiseptic1488 [7]
I think the answer is most likely be J.

The first (F) one the population of the predator increases hugely while the population of the prey was neutral. And so both population didn’t seem to have any connection. Same goes for H. Graph G doesn’t make sense at all the population of the prey didn’t exist throughout the time in the graph but only exist in one single point of time and then just vanish again so that shouldn’t be the answer either.
In graph J, you can see the correlation between the two populations as the predator goes up and so does the prey.
You can search up on google predator-prey relationship graph to get better understanding.
