Adhesion and cohesion effect every water molecule on Earth and their interactions with other molecules.

The ability of similar molecules (of the same substance) to adhere to each other as a result of mutual attraction is the quality known as cohesion. The capacity of distinct molecules or surfaces to attach to one another is referred to as adhesion. Solids, for instance, possess excellent cohesive qualities, which allow them to avoid adhering to the surfaces with which they come into contact.

Cohesion: Water has a natural tendency to attract more water. Adhesion: Water has a tendency to draw other substances to itself. Both adhesion and cohesion are qualities of water that have an effect on each and every water molecule on the planet, as well as the way water molecules interact with the molecules of other substances.

Answer:

Krill is an zooplankton species that is extremely abundant in Antarctic water bodies. These zooplanktons feeds on phtoplanktons present in the Antarctic water bodies. Therefore, in antarctic food chain Krill belong to primary consumer trophic level. In Antarctic they are source of food for seals, penguins, whales, fishes and birds. These are included in secondary, tertiary and quaternary trophic levels of the food chain. The drop in the size of the krill population will result in limitation of populations of species at higher trophic levels. As, many food chains are interconnected to form a food web therefore, the drop in size of Krill in one food chain will also affect the overall food web of Antarctica.

Final answer:

Fraternal twins are no more similar genetically than are regular, non-twin siblings. Fraternal twins have the same level of genetic similarity as non-twin siblings because they come from different eggs fertilized by different sperm. Their similarity in IQ likely stems from similar environmental treatments rather than genetics.

Explanation:

Fraternal twins are no more similar genetically than are regular, non-twin siblings. Fraternal twins develop from two different eggs that are fertilized by different sperm, meaning their genetic material varies the same as in non-twin siblings. Although fraternal twins may have more similar IQs than do nontwin siblings, this similarity in IQ is likely due to the fact that they are treated more similarly than are siblings in terms of environmental factors, rather than having more genetic similarity.

Explanation:

The rough endoplasmic reticulum (RER) is responsible for assembling some cell membrane components, and modifying proteins, and has ribosomes for protein synthesis. It also produces phospholipids for the cell membrane.

The cellular structure that assembles some components of the cell membrane, modifies proteins, and has ribosomes attached to it is the rough endoplasmic reticulum (RER). Ribosomes are the cellular structures responsible for protein synthesis. They are found attached to the RER, synthesizing proteins that are then transferred into the lumen of the RER, where they may undergo further modifications such as folding or receiving sugar chains. In addition to protein modification, the RER synthesizes phospholipids for the cell membrane. The modified proteins and newly made phospholipids are packed into vesicles, which then travel to and fuse with the Golgi apparatus for final modifications before being transported to their final destinations, such as the plasma membrane.

Answer: Endoplasmic reticulum

Explanation:

The endoplasmic reticulum is a membrane bound organelles which is found in the eukaryotic cell. This is found in the eukaryotic cell that forms a inter connected network of flattened membrane- enclosed in the sacs.

The enclosed sac or tube like structure in the cell is known as cisternae. It is a double membrane bound organelle which helps in the modification and sorting of proteins.

The correct answer is endoplasmic reticulum.

The given statement is false.  

The territorial behavior is an intra-species social behavior of the organism. In territorial behavior, the organism marks its territory and prevents it from the incursion of the other members of the same species. This behavior is not an inter species behavior, so, the effectiveness of the marking of the territory remains within the same species.  

The major functions of the lymphatic system include:

1. removing interstitial fluid from tissues

2. absorbs/transports fatty acids

3. transports white blood cells to and from lymph nodes into the bones

4. Transports antigen cells to the lymph nodes where the immune response is activated.

The lymphatic system is part of the body's immune system, performing three main functions: maintaining fluid levels in the body's tissues, absorbing fats from the digestive system, and protecting against infections.

The lymphatic system is a crucial part of the body's immune system. It has three major functions: maintenance of fluid levels in the body's tissues, absorption of fats from the digestive tract, and protection against infections.

The lymphatic system helps maintain fluid levels by collecting excess fluid and proteins from tissues and returning them to the bloodstream. This process prevents swelling and helps with circulation.

The lymphatic system also plays a significant role in the absorption of fats from the digestive system. Lacteals, special lymphatic vessels located in the lining of the small intestine, absorb dietary fats that cannot be transported directly into the bloodstream, and then transport them to the blood circulation.

Last but not least, the lymphatic system is essential for our body's defences. Its complex network of lymph nodes, vessels, and organs such as the spleen and thymus serve as filters, trapping microbes, cancer cells and foreign substances, which are then destroyed by lymphocytes.

The abiotic factors in the community have changed as the vegetative cover increases: more vegetative cover leads to the consumption of more water due to the presence of life forms; a dense forest is the result of less sunlight on the ground; and so on.

Abiotic factors are non-living physical and chemical elements in the environment that can influence the growth and behavior of living organisms, such as temperature, light, water, soil, and air quality and these factors, determine species survival rate, can have a significant impact on the structure and functioning of a community, for example, if a community is located in an area with cold winters, only species that are adapted to survive in cold temperatures will be able to survive there.

Hence, the abiotic factors in the community have changed as the vegetative cover increases: more vegetative cover leads to the consumption of more water due to the presence of life forms; a dense forest is the result of less sunlight on the ground; and so on.

Cell is like a factory because Cells and factories are analogous because they operate in a methodical manner, with various parts carrying out specific functions to achieve a larger goal. For example, factories produce goods using blueprints, while cells carry out functions like protein synthesis based on DNA instructions

Cells are often compared to factories due to their similar functional structures and operations. For instance, a factory has different departments that specialize in different functions, in the same way, a cell has different organelles each performing a specific role to maintain the cell's overall function, much like a factory's assembly line.

Each cell contains genetic instructions in the DNA much like the blueprints used in a factory. The Proteins, which are crucial for most of the cell's functions, are produced in the ribosomes, similar to a commodity being produced in a factory. This analogy is further highlighted by the cell cycle, where cells grow and divide to produce more cells in a controlled and systematic manner similar to a production line in a factory.

As both cells and factories operate in a systematic and controlled manner, with several small components working together to achieve a larger goal — survival in the case of cells, and production in the case of factories.
