The structure that connects the placenta to the embryo would be the <u>umbilical cord.</u>
Answer: c. Dead organic matter will accumulate on the forest floor; plant growth will decline because of a lack of nutrients and the loss of mycorrhizal partners.
Explanation:
The fungi are the eukaryotic organisms. In nature their role is to decompose the organic matter generated after the death of the living organisms. Some of these fungi lives in symbiotic mutualistic association with the plant roots so as to provide the minerals present in the soil and in return they receive the nourishment from the plants.
The treatment of the forest ecosystem enclosed in a greenhouse with the fungicide will negativity affect the forests. As the dead organic matter will be left undecomposed which will create a large amount of biodegradable waste and in absence of the mycorrhizal partners the plants will not grow properly in the absence of vital nutrients.
No, because there is no oxygen.
Haploid cells have one set of chromosomes while haploid cells have two sets of chromosomes.
Answer:
the chorion, the allantoids, the amnion and the yolk sac.
Explanation:
The amniotic egg has four layers. All of these layers are enclosed by a shell
The chorion helps for gas exchange. It's the layer that covers the whole embryo
The allantoid is a sac that helps with gas exchange but also is the one that encloses the wastes of the embryo during the development into the egg, one analogy is with the garbage bag, where all the waste is lookup
The amnion is the layer that protects the embryo, is like a jacket that surrounds the embryo
The yolk sac is the one that has the nutrients that are necessary for the embryo throughout all the development. It is like a lunch box for the embryo
