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.

list 3 differences between sun leaves and shade leaves
Answers
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.

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.
