Answer:
I sure hope this helps you!
Explanation:
Flying through the air I feel in need of food. Down under me is a beautiful ocean. On that oceans surface, there are lots of phytoplankton. Enough for me, enough for my family. This phytoplankton down under me has lived its life, eaten other organisms, and those organisms eat organisms. Now, is my turn. Tis the circle of life, they eat, I eat. Someday, something will eat me. Eating is very important to the living kind. It helps us stay healthy and alive. This, is my story of The Importance of Upwelling.
Answer:
Use the first numbers to assign the treatment to the individuals.
Explanation:
The names of the individuals are:
1. Amanda: 20742
2. Scott: 05310
3. Tessa: 65921
4. Jon: 01652
5. Elizabeth: 75532
6. Kevin: 95621
7. Robin: 12097
8. Mike: (no number assigned)
I am assuming that the numbers that are random and are given to them in the order seen. First, remove all the persons that have a zero or 9 in front and no number assigned to their names . That leaves 20742 , 65921, 75532, 12097.
The four individuals would be Amanda, Tessa, Elizabeth and Kevin.
There are other ways to do this randomized selection, that also involves eliminating the numbers with zeros and those that have been used in the same numbers.
It can also be done by using the first two digits, also eliminating the zero and assigning the numbers from lowest to highest alphabetically in ascending or descending order.
Four volunteers will always be chosen based on any of these methods.
Answer: The correct answer is-
A. organs, but no true body cavity.
Based on the presence of body cavity ( also called coelom), multicellular animals can be classified as acoelomates ( no true body cavity), coelomates ( having true body cavity), pseudocoelomates ( false body cavity).
Roundworms are pseudocoelomic. This means that organs are present but the body cavity is not lined by mesodermal epithelium.
Body cavity is present between the external wall of body and the intestine and it baths the different body organs.
Thus, option A) is the right answer.
Answer:
Option A
Explanation:
All bilateral organisms have coelomates (cavity). However a Pseudocoelomate organism have a false cavity. By false cavity, we mean that there is a body cavity which is filled with fluid and all internal organs bathe in it including alimentary canal system , reproductive system etc. Unlike a coelom, Pseudocoelomate organism do not have body cavity completely lined with mesodermal cells.
hence, option A is correct
b. False
PLATO
A.
More offspring are born than can be supported by the environment.
B.
If too many offspring are born, they will be forced to compete for resources.
C.
Genetic variation leaves some offspring better adapted to their environment than others.
