Answer:
Explanation:
The genes in DNA encode protein molecules, which are the "workhorses" of the cell, carrying out all the functions necessary for life. For example, enzymes, including those that metabolize nutrients and synthesize new cellular constituents, as well as DNA polymerases and other enzymes that make copies of DNA during cell division, are all proteins.
In the simplest sense, expressing a gene means manufacturing its corresponding protein, and this multilayered process has two major steps. In the first step, the information in DNA is transferred to a messenger RNA (mRNA) molecule by way of a process called transcription. During transcription, the DNA of a gene serves as a template for complementary base-pairing, and an enzyme called RNA polymerase II catalyzes the formation of a pre-mRNA molecule, which is then processed to form mature mRNA (Figure 1). The resulting mRNA is a single-stranded copy of the gene, which next must be translated into a protein molecule.
Describe the steps in making, packaging, and exporting a protein from a cell.
Answer:
1. proteins are assembled on ribosomes
2. proteins targeted for export to the cell membrane, or to specialized locations within the cell. They complete their assembly on ribosomes bound to the rough ER
3. Newly assembled proteins are carried from the rough ER to the golgi apparatus in vesicles
4. the golgi apparatus further modifies proteins before sorting and packaging them in the membrane-bound vesicles
5. vesicles from the golgi apparatus are shipped to their final destination in or out of the cell

C. As nutrients increase, the number of life-forms stays the same.
D. As nutrients decrease, the number of life-forms stays the same.
Answer:
O A. As nutrients increase, the number of life-forms increases.
Explanation:
common sense
The statement that best describes the relationship between nutrients and life forms in an estuary is as follows:
As nutrients increase, the number of life-forms increases.Thus, the correct option for this question is A.
What do you mean by Estuary?An Estuary may be defined as a type of ecotone that signifies the transitional zone of two different ecosystems which include the freshwater river ecosystem and the marine water ocean ecosystem.
In this ecotone, the characteristics of both ecosystems are present. Hence, it has a high biodiversity as compared to both ecosystems individually. This region shows maximum diversity and is thus known as the edge effect.
This illustrates that when nutrients in the ecotone increase, the number of life forms i.e. biodiversity increases.
Therefore, the correct option for this question is A.

what will most likely happen to the squirrel?
Could you give me more background about said squirrel.
Answer:
C) The squirrel will starve if it can't find enough food
Explanation:
If the question is “This squirrel lives in a forest and eats only acorns. What will MOST LIKELY happen to the squirrel if the oak trees in this forest start dying of a disease? A) The squirrel will adapt to less food. B) The squirrel will not be affected at all. C) The squirrel will starve if it can't find enough food. D) The squirrel will eat berries instead of acorns to survive.” then the answer would be C because the squirrels usually on the acorns from trees, and if the trees are gone or there isn’t any food left on the tree the squirrels will starve because they were depending on the acorns for food.
In the 1960s the molecular biologist George Streisinger developed the strand- slippage hypothesis. Streisinger noticed that mutations occurred in areas of DNA that contained many repeated sequences. When a strand -slippage occurs, an insertion mutation can result. How does the insertion mutation affect the DNA?
The insertion mutation affects the DNA cause Nitrogenous bases are added to the mix. This is further explained below.
What is a DNA?Generally, DNA is ssimly defined as a molecule found inside cells of a living organism that holds the genetic information.
In conclusion. Nitrogenous bases are added to the mix with the insertion of mutation.

Which type of rock has a coarse texture due to slow cooling in magma chambers?
A.extrusive
B.intrusive
C.metamorphic
D.sedimentary
Answer: Intrusive
Explanation:
If magma cools slowly, deep within the crust, the resulting rock is called intrusive or plutonic. The slow cooling process allows crystals to grow large, giving intrusive igneous rock a coarse-grained or phaneritic texture.
Hope this helps!! :D
Answer:
intrusive
Explanation:
Intrusive igneous rocks form at some depth within the crust due to slow cooling of magma, resulting in formation of large crystals. Individual crystals can be seen with the naked eye. These rocks are termed texturally as coarsely crystalline or phaneritic.

Humans have found that we can eat the space cow, and it's delicious! There are no laws currently in place protecting the environment of Planet Z. What would happen to the populations of both the Space Cows and the Vaderians if humans began to hunt for Space Cows on Planet Z?
Will it increase or decrease and why?
if humans begin hunt the space cows they will eventually become extinct causing the vaderians to lose a main source of food which would most likely cause their population to also decrease.

A. It's moving down the concentration gradient.
B. Energy is needed to make this happen
C. It's facilitated diffusion.
D. It's osmosis.
Answer:
A) it is moving down the concentration gradient
Explanation:
Brownian motion will cause the molecules (or ions) to spread/diffuse from where they are more concentrated to where they are less concentrated until they are equally distributed in that space (Figure). When molecules move in this way, they are said to move down their concentration gradient.

what are the different ways of storing tools and equipment safe
answer is included in the picture below.
Answer:
Step 1
Delegate a portion of your garage, shed or basement closet as a place to store tools. Clean out the junk and clutter and make a space only for tools. Figure out how much space is needed for the amount of tools you have. Sweep away cobwebs, dirt and other foreign matter. Get a shelving unit and store chemicals, liquids and paint substances out of the reach of children and pets.
Step 2
Find the parts. Locate cords, bits, nails and screws and organize them. Allocate plastic bins to store smaller household tools. If you have a large tool collection, organize by type for easy location. Keep the parts for each specific tool close by.
Step 3
Clean out dirt and debris from tools. Oil power tools to lubricate moving parts. Repair loose handles and clean out oil or other fluids used to power the tool. Sharpen blades and replace worn out parts.
Step 4
Set up racks. Mount commercially available racks along the wall of your garage or storage area to hang garden tools, cords and other equipment. Screw racks into the wall with screws recommended by the manufacturer and a power drill. Wind long cords in a loop and hang from rack. Place tools on racks by the handle. Draw the outline of the tool with a permanent marker to identify its place, or use labels to mark the location.
Step 5
Create a library. For tools and appliances that have various functions, designate a library area or bin within the storage space for user manuals and warranty sheets. Store the booklets alphabetically and in a dry area. Type up a sheet listing all of the books to create simple table of contents.

What can a scientist
learn by observing the
behaviors of a particular
animal?
Answer: Sense food, Predators
Explanation: They can observe the animals odor and they can also observe the animals predators.
Scientists are inspired to the survey of animal behavior for a variety of reasons, and the ground is pretty varied, ranging from feeding behavior and habitat selection research to mating behavior and social organizations.
What is animal behavior?Animal behavior encompasses all of the ways in which animals interact with other organisms and their physical surroundings.
Behavior can also be defined as a change in an organism's activity in response to a stimulus, an external or internal cue, or a combination of cues.
Animal behavior connects the molecular and physiological aspects of biology to the ecological.
Behavior is the link between organisms and their surroundings, as well as between the nervous system and the ecosystem. One of the most important aspects of animal life is behavior.
Animal research helps scientists understand how living creatures, both human and animal, function.
Animal research allows us to get a close-up look at living organisms and how their physical, chemical, and functional life systems function.
Thus, this way, a scientist can learn many varied things regarding organisms by learning animal behavior.
