Which of the methods of transport into or out of the cell require energy? Which do not?

Answer:

ATP stands for adenosine triphosphate. It is a molecule found in the cells of living organisms. It is said to be very important because it transports the energy necessary for all cellular metabolic activities. Without ATP, various metabolic activities in the human body cannot take place.

Answer:

The correct answer is - two plates moving past each other.

Explanation:

The San Andreas Fault is a boundary or long valley that present at or represent the two different tectonic plates,  North America plate meets the Pacific plate.

The origin of this valley is almost 30 million years ago in California. At that time both tectonic plates the Pacific Plate and the North America plate first met and slid past one another to make a boundary called a strike-slip fault. These are cause the biggest earthquakes.

The answer is 5'- CGU- 3'

Explanation:

DNA is the genetic material of living organisms that contains information on how to produce proteins needed for the normal functioning of the cell. This information is encoded in the nucleotide bases contained in the DNA molecule. The information is expressed via the process of transcription and translation.

Transcription is the process whereby DNA is used to synthesize a mRNA molecule. In this case, a particular triplet of bases in the coding strand of DNA is 5'-CGT-3. This undergoes transcription to give 3'- GCA- 5'.

This further undergoes translation with the aid of a tRNA, which carries the following anticodon component which is complementary to the mRNA codon: 5'- CGU- 3'.

Explanation:

Limiting resources like adequate food, shelter, water, mating partner, etc. determine the carrying capacity of an environment for a species.

Carrying capacity may be defined as the maximum number of individuals of a particular species that can be supported by the habitat. The carrying capacity of any habitat mostly depends on the following two factors:

The Carrying capacity of the same habitat may be different for different species. It significantly depends on how a species utilizes the resources which are present in the habitat. These resources are limited in terms of availability and could be consists of biotic and abiotic factors.

Therefore, limiting resources like adequate food, shelter, water, mating partner, etc. determine the carrying capacity of an environment for a species.

Continental Creep

Explanation:

The definition of Continental Creep is:

Continental drift is the hypothesis that the Earth's continents have moved over geologic time relative to each other, thus appearing to have "drifted" across the ocean bed. The speculation that continents might have 'drifted' was first put forward by Abraham Ortelius in 1596.

Energy is a universal term which can be used in different activities in day to day life,  can exist in many forms. All forms of energy are either kinetic or potential.

The different forms of energy on earth include The sun is considered the elemental form of energy, it is a quantitative property which can be transferred from an object to perform work.

The International System of Units system of energy is joule which are named after James Prescott Joule and it is the unit equal to the energy expended in applying a force of one newton through a distance of one meter.

PLEASE MARK ME AS A BRAINLIST!!

Answer;

shortly:-The main differences between prokaryotic and eukaryotic cells are the presence of a nucleus, the size and complexity of the ribosomes, how the cells reproduce and the presence of a cell wall. Ribosomes: In eukaryotic cells, the ribosomes are bigger, more complex and bound by a membrane

but you need more explanation:-

Eukaryotic organisms are made out of cells that possess membrane-bound organelles and a membrane-bound nucleus. The genetic material of eukaryotic organisms is found within the nucleus of the cell and chromosomes are how the DNA is organized within the nucleus. Eukaryotic cells comprise both single-celled and multicellular forms of life. Eukaryotes compose the bodies of all protists, fungi, plants, and animals.

Eukaryotic cells display an impressive amount of diversity, and they are capable of being many different shapes and sizes. The structure of a eukaryotic cell is tied closely to its function. For example, the epithelial cells that make up the human body are usually divided into three different types: squamous, cuboidal, and columnar. Each of these different cell types has a different form that enables it to carry out its respective functionsEukaryotic cells may have the following parts:

   Cell wall (only plant cells)

   Plasma membrane

   Nucleolus

   Nucleus

   Chromosomes

   Vesicles

   Golgi apparatus

   Ribosomes

   Endoplasmic reticulum

   Cytoplasm (and cytoskeleton)

   Lysosomes

   Mitochondria

   Centrioles

   Chloroplasts (only plant cells)

Prokaryotic cells are almost always much smaller than eukaryotic cells. The size of a prokaryotic cell is usually around 1 µm, while the size of animal cells and plant cells are usually between 10 to 100 µm. Because eukaryotic cells are much larger than prokaryotic cells, they have evolved special methods of transporting substances around the cell that bacteria don’t have.

Each of these different cell types has a different form that enables it to carry out its respective functions.

The distinction between eukaryotes and prokaryotes is based upon two theories regarding the role of cells in biology. Cell theory states that all living things are made out of cells, and biogenesis theory proposes that all living cells came from other existing cells, so cells cannot spontaneously arise from non-living things (abiogenesis). For cells to comprise all the life we see on Earth they must be able to organize proteins and other chemical compounds. Individual cells are capable of keeping chemical processes isolated and compartmentalized so one chemical process doesn’t interfere with another chemical process, which runs the risk of disrupting the delicate chemical balance of the cell and leading to cell death.

   “A cell is regarded as the true biological atom.” — George Henry Lewes

To keep the chemical processes within a cell isolated and organized, cell components stay enclosed within a membrane that serves as the barrier between the interior of the cell and the cell’s environment. The membrane of a cell is selectively permeable, meaning that the cell will allow some chemical compounds into the cell and not others. The membrane of the cell is made out of a phospholipid bilayer, two groups of lipids arrayed in layers and facing opposite directions. Smaller compounds can penetrate the phospholipid bilayer, but larger compounds must enter the cell using a pore in the cell membrane.

The cell membrane has various methods of regulating how chemicals move in and out of the cell. Diffusion refers to the tendency of molecules at high concentrations to distribute out to areas of lower concentration until the concentrations across the two areas equalize. Osmosis is similar to diffusion, but it refers to the movement of a solvent across a boundary instead of a solute. This helps to equalize a solute that can’t move through a boundary. Selective transport, the movement of molecules within the cell, is handled by both membrane pumps and membrane channels.

Answer:

The environmental factor that could lead to a decrease in genetic variation in a tuna population is an increase in pollution (second option).

Explanation:

There is a correlation between genetic variability and environmental pollution, the latter being a factor that impacts negatively on the variability of a specific population.

The concept of pollution stress not only implies a low rate of reproduction, but it is also a factor that prevents genetic exchange with other populations, which is a factor that makes the genetic variability decrease in a population.

For these reasons an increase in pollution implies a decrease in genetic variability in a tuna population.
