Important Ions move from low to high concentration while using a membrane protein. Which of the following is true? Question 5 options:

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.

Answers

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.

Describe the steps in making, packaging, and exporting a protein from a cell.

Answers

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

What is the difference between transpiration and diffusion

Answers

Answer:

In sunlight the concentration of water and oxygen molecules just inside the stomata is higher than the concentration of the air around the leaves so water vapor and oxygen diffuse, or move out, from the leaves through the stomata. Diffusion, then, is a physical driver of transpiration. Hope this helps!

There are four kinds of tissues in the human body. They are muscle, nervous, connective, and epithelial tissues. Which of the following is true about all of these tissues?

Answers

Answer: Epithelium tissue refers to the sheets of cells that cover exterior surfaces of the body, lines internal cavities and passageways, and forms certain glands. Connective tissue binds the cells and organs of the body together and functions in the protection, support, and integration of all parts of the body. Muscle tissue is excitable, responding to stimulation and contracting to provide movement, and occurs as three major types: skeletal (voluntary) muscle, smooth muscle, and cardiac muscle in the heart. Nervous tissue is also excitable, allowing the propagation of electrochemical signals in the form of nerve impulses that communicate between different regions of the body

Which type of rock has a coarse texture due to slow cooling in magma chambers?

A.extrusive
B.intrusive
C.metamorphic
D.sedimentary

Answers

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.

Which accurately describes the relationship between nutrients and life-forms in an estuary?
O A. As nutrients increase, the number of life-forms increases.
0
B. As nutrients decrease, the number of life-forms increases.
O
C. As nutrients increase, the number of life-forms stays the same.
D. As nutrients decrease, the number of life-forms stays the same.

Answers

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 are the different ways of storing tools and equipment safe

Answers

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.

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.

Mutations are not passed from parent to offspring?

Answers

Answer:

Mutations rarely occur.

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?

Answers

The insertion mutation affect the DNA by changing certain cells

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.
