Answer:

D or B?

Explanation:

Answer:

option 1,3, and 4

-Membrane proteins may be enzymes to catalyze metabolic reactions within the cell.

-Channel proteins allow a specific molecule to cross the cell membrane that is unable to cross the phospholipid bilayer unassisted.

-Receptor proteins bind to ligands, initiated cell signaling pathways.

Explanation:

I did the assignment on USATestprep and got them right.

The statements accurately reflect the structure and function of the phospholipid bilayer are:

1. Membrane proteins may be enzymes to catalyze metabolic reactions within the cell.

3. Channel proteins allow a specific molecule to cross the cell membrane that is unable to cross the phospholipid bilayer unassisted.

4. Receptor proteins bind to ligands, initiating cell signaling pathways.

Phospholipids are distinct compounds with many uses. They are common and serve as the primary building blocks of cellular membranes.

Phospholipids, which are arranged as lipid bilayers, are crucial for the composition and operation of biological membranes. These layers contain proteins and carbohydrates that help in the transport of material from and to the cell.

Therefore, the correct options are 1, 3, and 4.

Answer:

Earth, both on land and in water. Wherever they

live, plants provide food and oxygen to the

creatures that live nearby – including humans!

In this activity we will examine both a

terrestrial (land) plant and an aquatic (water)

plant. They have many things in common, but the

Answer:

energy pyramid

Explanation:

An energy pyramid is a model that shows the flow of energy from one trophic level to the next along a food chain.

The cycle of energy is based on the flow of energy through different trophic levels in an ecosystem. ... At the first trophic level, primary producers use solar energy to produce organic material through photosynthesis. The herbivores at the second trophic level, use the plants as food which gives them energy.

Answer:biotic factors

Explanation:

They are living

Food availability, places to live, and water availability are all Abiotic Factors of an Ecosystem.

Biotic and abiotic factors make up ecosystems in which biotic factors are living things within an ecosystem such as plants, animals and bacteria, while abiotic are non-living components such as water, soil and atmosphere.

An abiotic factor is a non-living part of an ecosystem that shapes its environment. In a terrestrial ecosystem, the abiotic factors are temperature, light, and water. In a marine ecosystem, the abiotic factors are salinity and ocean currents. Abiotic and biotic factors work together to form a unique ecosystem.

Biotic components are living things that have a direct or indirect effect on other organisms in the environment such as animals, and microorganisms and their waste materials.

Thus, food availability, places to live, and water availability are all Abiotic Factors of an Ecosystem.

Explanation:

The air pressure descends as we ascend. In other words, they are inversely proportional.

The air pressure descends as we ascend the mountain because the air molecules that are above us in high altitudes are fewer than the number of air molecules that are above us in the base of the mountain. So, the exerted pressure of the molecules on ourselves is lower in high altitudes.

Due to the reason mentioned above, we can deduce that the only correct option is option number two since the other ones show increasing or the same pressure, which is not possible as we ascend.

A barometer is an instrument that is designed for measuring the changes in air pressure.  

Hence the option 3 is correct.

Explanation:

Shell size and shape vary between populations. On islands with humid highlands, the tortoises are larger, with domed shells and short necks; on islands with dry lowlands, the tortoises are smaller, with "saddleback" shells and long necks.

Answer:

Probably not. This is because the islands at Galapagos islands are all diverse and the turtles that live on each island have characteristics that help them survive on their island and not any other island so if you were to move one of the turtles locations it probably wouldn't survive because it doesnt have the needed characteristics do survive.

Answer:

The sodium–potassium pump is found in many cell (plasma) membranes. Powered by ATP, the pump moves sodium and potassium ions in opposite directions, each against its concentration gradient. In a single cycle of the pump, three sodium ions are extruded from and two potassium ions are imported into the cell.

The top left is the diploid parent cell

In the meiosis, the upper-most cell is the diploid parent cell; the below image explains the crossing over, and then independent assortment is seen in the order to make two haploid daughter cells at the end of meiosis I, and in meiosis II, four daughter cells will be formed.

Meiosis is a type of cell division that occurs in organisms that reproduce sexually and plays a crucial role in the formation of gametes, which are the cells that are involved in sexual reproduction, during this process, a cell's DNA is replicated, and then the cell divides into four daughter cells, each with half the number of chromosomes as the parent cell and this process is important because it ensures that the gametes produced by an organism will have the correct number of chromosomes, which is necessary for the proper development of the offspring.

Hence, in the meiosis, the upper-most cell is the diploid parent cell; the below image explains the crossing over, and then independent assortment is seen in the order to make two haploid daughter cells at the end of meiosis I, and in meiosis II, four daughter cells will be formed.

Answer:

When strand slippage occurs during DNA replication, a DNA strand may loop out, resulting in the addition or deletion of a nucleotide on the newly-synthesized strand. ... But if this does not occur, a nucleotide that is added to the newly synthesized strand can become a permanent mutation.

Answer:

A mutation is a change that occurs in our DNA sequence, either due to mistakes when the DNA is copied or as the result of environmental factors such as UV light and cigarette smoke. Mutations can occur during DNA replication if errors are made and not corrected in time.

Explanation:

This table shows that concentration of carbondioxide gas in snake's blood is higher in the blood due to respiration process but after breathing, the concentration of carbondioxide gas decreases in the blood while on the other hand, when the carbondioxide gas is lower in the blood, the concentration of oxygen increases due to loading of blood cells with oxygen in the lungs so one is increase whereas the other is decrease in concentration.

At picnics or parties, use for most any food that doesn't need a lid container.

Use in car trunk to store either clean or dirty rags.

Use to wrap up breakables for transporting.

Put babies dirty diapers, especially throwaways when you are going to use a public trash can.

Use to store or carry baseballs. You can get about 12 hardballs in a large bag or 6 softballs.

Use the bag to collect berries, pine cones, or any other little treasures you find on your nature walks.

Use to carry your caught fish home.

Use to bury your desceased pet parakeet, fish, gerbils or hamster. Just wrap them up in a bag and bury.

Use as a trash bag for your vehicle.

A large empty potato chip bag will make 2 one time picnic table place mats.
