How are gasses exchanged in the alveoli
Answer:
The alveolar walls and capillary walls share a membrane. That's how close they're getting. This allows oxygen and carbon dioxide to readily pass from the respiratory system to the circulation. Oxygen molecules bind to red blood cells as they return to the heart.
If catfish eat algae, and there's 20,000 kcal/m2 of energy stored as biomass in algae in a pond, how much energy stored as biomass in catfish in that pond would you expect there to be?
There will be 2,000 kcal/m² of energy stored as biomass in catfish in the pond.
What is Biomass?This is defined as the position of an organism in the food chain and 10 percent of energy stored as biomass in a trophic level is passed from one level to the next.
This is why the 10 percent of 20,000 kcal/m² which is 2,000 kcal/m² will be most likely present in the next level.

A.Energy and nutrients both flow in only one direction and are not cycled.
B.Energy is cycled and nutrients flow in one direction
C.Energy and nutrients are both cycled
D.Energy flows in one direction and nutrients are cycled
When it comes to the movement of nutrients and energy in the ecosystem, nutrients are cycled while energy moves in a specific direction.
Energy and nutrients in the ecosystemEnergy moves in the ecosystem from the producers to the consumers, and finally to the decomposers.
Nutrients, on the other hand, cycle between various components of the ecosystem - atmosphere, lithosphere, geosphere, hydrosphere, biosphere, etc.

list 3 differences between sun leaves and shade leaves
Answer:
Partial sun is between four and six hours of sun a day. Partial shade is two to four hours of sun per day. Shade, in gardening terms, means less than two hours of sunlight a day. Leaves which grow in the shade ('shade leaves') are generally larger in area but thinner than leaves which grow in full sunlight ('sun leaves'). Sun leaves become thicker than shade leaves because they have a thicker cuticle and longer palisade cells, and sometimes several layers of palisade cells.

The fluid that is formed when blood flows through the glomerulus and some components of the plasma enter the capsular space is called tubular fluid.
What is the fluid filtered out of the blood in the glomerulus called?
Filterable blood components include water, nitrogenous waste, and nutrients in an effort to be transferred into the glomerulus to shape the glomerular filtrate. Non-filterable blood components encompass blood cells, albumins, and platelets, so as to depart the glomerulus through the efferent arteriole.
Glomerular filtration is step one in making urine. It is the process that your kidneys use to clear extra fluid and waste merchandise out of the blood into the urine amassing tubules of the kidney, so they may be eliminated from your body.

Which strategy during the planning stages of a group project would most
likely prevent this problem?
It's clear to group members what tasks in a project need to be
completed, but some members are worried they that don't have the
skills necessary to completescertain tasks.
O A. Choose an organizer.
B. Choose roles
C. Identify deadlines.
D. Listen actively
Answer:
B. Choose roles
Explanation:
Choosing roles would be the best choice in order to avoid the problem stated, because certain people can be put to work on a certain section of the project (that they are suited for). That way, no one will feel as if they lack the skills to complete another part of the project.
Choosing an organizer wouldn't help much because they'd only be organizing the project itself, not the parts that people play within it. Identifying deadlines wouldn't help at all. It would cause stress if anything. Lastly, listening carefully also wouldn't help, because listening to so-and-so won't do anything to the problem at hand. You'd just be listening.
hope this helps!
The strategy during the planning stages of a group project that would most likely prevent the problem of some members being worried about not having the necessary skills to complete certain tasks is to choose roles. The correct option is B.
What is group project?A group project is a collaborative effort where a group of people works together to achieve a common goal or complete a task.
By deciding on roles, each group member can be assigned tasks that are best suited to their skills, interests, and experience.
This can help to ensure that everyone in the group is confident in their ability to complete their assigned tasks and that the workload is evenly distributed.
The most effective strategy for avoiding the problem of members being concerned about not having the necessary skills to complete certain tasks is to assign roles during the planning stages of a group project.
Thus, the correct option is B.

Suppose a new resort hotel is built on a hawksbill sea turtle nesting site, and hotel guests start removing the queen angelfish from the nearby reef to stock their home aquaria. If the hawksbill sea turtles and queen angelfish are removed, which organism is most likely to benefit?.
Answer:
Sponges, Anemones, Squid and Shrimp.
Explanation:
Those are the organisms that the sea turtle feed on.
Sponges, Anemones, Squid and Shrimp are most likely to benefit since the sea turtles and angelfish feed on them.
What happens if hawksbill sea turtles and queen angelfish are removed?Hawksbills contribute to the preservation of coral reef health. Reef fish have easier access to food because they clear sponges and other prey off the reef's surface. They are also valuable for tourism and have cultural significance.
Queen angelfish are omnivores that primarily eat algae and sponges. They are opportunistic and will consume jellyfish, soft corals, and sea fans. Young fish clean larger kinds of fish by removing parasites from their skin so that they can be eaten.
The populations of the organisms that Hawksbill Sea Turtles and queen angelfish consume, such as sponges and sea urchins, would probably explode if they became extinct. This would result in widespread erosion and possibly the collapse of marine ecosystems like coral reefs.
