loblolly pine trees

Explanation:

Population density refers to the amount of organisms living in a particular area:

            Population density = \frac{number of organisms}{Area}

Area of the forest = 10acres

Population densities of:

  White-tailed deer = \frac{8 white tailed deer}{10acres}

                                 = 0.8white tailed deer/acres

   Coyotes = \frac{7 coyotes}{10acres}= 0.7coyotes/acres

   Armadillos = \frac{45 armadillos}{10acres} = 4.5armadillos/acres

   loblolly pine = \frac{231loblolly pine trees}{10acres} = 23.1loblolly pine trees/acre

The population with the highest density is that of the loblolly pine trees with 23.1 of the trees in an acre.

Which of these statements about trophoblast is false?
lukranit [14]

Answer:

The statement C that says ''is derived from the inner cell mass'' is false.

Explanation:

The trophoblast is a structure composed of a set of cells (cytotrophoblast and syncytiotrophoblast), which are shaping the outer layer surrounding a blastocyst, during the earliest stages of embryonic development that mammals pass.

The trophoblast provides nutritive molecules to the developing embryo and facilitates its implantation to the uterine wall due to its ability to erode the tissues of the uterus, that is, it is responsible for making it possible for the embryo to be implanted in the uterine endometrium. Thus, the blast can join the cavity formed by the uterine wall, where it will absorb nutrients from the fluid from the mother.

During the third week, embryonic development includes the development of the trophoblast. At the beginning, the primary villi are formed by the internal cytotrophoblast which is surrounded by the outer layer of syncytiotrophoblast. Then, the cells found in the embryonic mesoderm are directed to the primary villous in the third week of gestation and when it ends, the mesodermal cells begin to be singled out to form blood vessel cells.
