The behavior of zebras and other grazers banding together while grazing indicates their social behavior to protect themselves and their group mates from predators.
Grazing: It is a process in which herbivores roam from one place to another in search of grass, small plants, etc which are the main source of food for them. It involves forage search, selection of forage, and eating the selected forage. Different animals differ in the type and method of searching and eating forage. This different grazing behavior makes them different from one another.
Although, one common thing which is observed in these grazing animals is the practice of grazing in bands or groups. This is generally noticed in the area where they have more danger from predators so they practice this banding method as a protective measure because predators find it difficult to attack groups and they get less chance to kill a lone individual.

In the movement of water across a selectively permeable membrane lab. What substance was actually able to pass through the membrane?
If the membrane is selectively permeable or semipermeable membrane molecules, such as hydrocarbons and oxygen can only cross the cell membrane.
Larger molecule like hydrocarbons and carbon cannot cross the cell membrane . water can only cross between the lipids .Hence ,Osmosis is a special type of diffusion, that allows diffusion of water across a semipermeable membrane. Water readily crosses a membrane down its potential gradient from high to low potential. Osmotic pressure is the force required to prevent water movement across the semipermeable membrane. Any substance crosses the cell membrane by two basic ways passive transport, which requires no energy; and active transport, which requires energy.

11. In plant cells grown in the presence of a metabolic poison that specifically inhibits mitochondrial F1ATP synthase, one would expect:
In plant cells grown in the presence of a metabolic poison that specifically inhibits mitochondrial F1ATP synthase, one would expect: An increase in the pH difference across the inner mitochondrial membrane.
The electron transport chain can no longer pump electrons into the intermembrane space. The pH of the intermembrane space would increase, lowering the pH gradient and stopping ATP synthesis. The function of ATP synthase is to form ATP from ADP and inorganic phosphate (Pi) in the F1 sector. This is possible due to the energy derived from the gradient of protons that cross the inner mitochondrial membrane from the intermembrane space into the matrix via the Fo part of the enzyme.

Respiratory and Circulatory System:
= > The respiratory system and the circulatory system are two important organ systems in the human body. The respiratory system involves all passageways and organs involved in breathing, while the circulatory system involves the heart and blood vessels.
Answer and Explanation: 1
= > The respiratory system and circulatory system interact in both the enriching of blood with oxygen and the delivery of oxygen-rich blood to the tissues.
= > In the lungs, air fills small sacs called alveoli. The alveoli are made of thin sheets of squamous epithelial cells suffused with capillaries. The epithelial tissue allows oxygen from the inhaled air to pass into the blood of the capillaries while allowing waste gases, like carbon dioxide, to escape the blood and be exhaled from the body.
= > After leaving the lungs, the blood returns to the heart, where it is pumped back out to the rest of the body. The oxygen-rich blood travels through the blood vessels and eventually into capillaries that suffuse the tissues of the body. In the tissues, the oxygen from the blood is extracted and delivered to the cells to power their metabolic functions.
= > Both processes are vital to the survival of an organism because tissues would die without the delivery of oxygen that begins in the interaction of the respiratory system and circulatory system.

The respiratory and circulatory systems interact in the supply of oxygen to the cells of the body.
Circulatory and respiratory system interactionThe respiratory system supplies oxygen into the blood. The circulatory system transport oxygenated blood to tissues/cells that require oxygen and supply them with the gas.
On the other hand, carbon dioxide waste that needs to leave the body system is transported by the blood from cells/tissues to the respiratory system. The respiratory system gets rid of this waste.
Without oxygen supply and getting rid of carbon dioxide, the cells of the body will die in no time.

In photosynthetic eukaryotes, the electron transport chain is observed on the thylakoid membrane. here, light energy drives electron transport through a proton pump and the ensuing proton gradient causes the next synthesis of ATP.
The light reactions are finished by means of the thylakoid membrane protein complexes photosystem II (PSII), cytochrome b6/f complicated, photosystem I (PSI), and ATP synthase. Many proteins that play crucial capabilities in both reactions have poor roles in viral pathogenesis.
The most outstanding thylakoid transporter is the proton-translocating ATP-synthase.

It may be easy for two neighbors to agree to drain a meadow, which they possess in common, to grow crops. However, when the meadow is much larger and reaches thousands of people, the solution is more difficult because of the free rider problem.
What is the free-rider problem:
The free-rider problem arises when people enjoy the benefits of a common resource without making any contributions towards it, resulting in market failure. Market failure refers to when a good or service gets distributed inefficiently in a market.
When only two neighbors share a meadow, they can easily hold each other accountable for draining the meadow on time. However, when the meadow can be accessed by thousands of people, it is difficult to hold one person accountable for draining it. Everyone will want to use the meadow to grow their crops. However, none will be willing to take the responsibility of draining it since they know that if they wait for someone else to drain the meadow, they can benefit from it without having to do any work themselves. As everyone will dodge the responsibility to drain the meadow with the intention of free riding, it is likely that no one will end up draining the meadow.

Homologous and analogous structures are two types of evolutionary evidence, taken together, provide strong evidence for when extinct species most likely diverged from common ancestors, relative to other events happening on Earth.
Several types of evidence support the theory of evolution: If two or more species share a unique physical feature, such as a complex bone structure or body plan, they can all inherit this property from the common ancestor. Physical traits shared through evolutionary history (common ancestor) they say they are homologous. Not all physical properties that look similar are signs of common ancestry.
