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

Answers

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?.

Answers

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.

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.

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 ecosystem

Energy 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.
