Answer;
The three statements that are true, include;
A diploblast has no mesoderm.
A pseudocoelom has the same functions as a true coelom.
In a coelomate, the tissue lining the inner side of the body cavity arises from the same germ layer as the tissue lining the outer side of the body cavity.
Explanation;
-Diploblastic animals are animals possessing two major tissue layers. These include the outer layer (the ectoderm) and the inner layer (the endoderm). Unlike the triploblastic animals , the diploblastic animals lack the third middle layer, the mesoderm.
- Coelom is the body cavity which exists between the mesoderm and endoderm while pseudo coelom is the body cavity which is present inside the mesoderm. Both the coeloms and pseudocoeloms are used as hydrostatics skeletons.
-Coelomate animals are animals that have a "true" body cavity or coelom and organs are in cased in peritoneal membrane.
During respiration, the diaphragm moves upwards and returns to dome shape from the flattened shape before during expiration.
This movement of diaphragm can decrease the lung volume, increase the pressure inside and thus force the air out. This process is expiration.
However, if we breathe in again, which makes that inhalation, the diaphragm moves downwards into a flat shape so that it can increase the lung volume and thus we can breathe in as much air we can. This process is completely opposite from expiration.
Answer;
-Citrus trees are angiosperms and dicots. Citrus tress have herbaceous or woody stems.
Explanation;
-Angiosperms are vascular flowering plants. They are divided into two classes: the monocotyledonous (monocots) and the dicotyledonous (dicots). This distinction is based on the number of cotyledons, the food storage structures in their seeds. Monocots have one cotyledon while the dicots have two.
-Citrus tree is an example of Angiosperm, dicotyledonous plant. Additionally citrus tree have herbaceous or woody stems.
<span>x = bracelets
y = necklaces
There are 23 of them in total (necklaces + bracelets)
x + y = 23
bracelets are $2 each and necklaces are $3 each...totaling $55
2x + 3y = 55
