Muscle, cartilage, bone, and heart all develop from the mesoderm layer of the blastocyst.  

Further Explanation

A germ layer is a layer of cells that forms during embryonic development. It is primarily a group of cells in the embryo that connect with each other as the embryo are formed and take part in the formation of all tissues and organs.

Animal forms two or three gem layers. The germ layer formed early in the embryonic life and the process through which they are formed is called gastrulation. When gastrulation takes place, a cluster of cells known as blastula, transform into two primary gems layer. These two primary gems layer are called inner layer and outer layer.

The inner layer is also called endoderm and the outer layer called ectoderm. However, there are two primary germ layers that diploblastic organism has.  Diploblastic organism has multiple symmetrical body axes such as anemones and jellyfish

All other animals which are triploblastic, as endoderm and ectoderm transformed to produce a third germ layer called mesoderm. All the three germs layer combined will give rise to every organ and tissue in the body from hair to digestive tract.  

Although among species, gastrulation differs, but the process remains the same.

Answer:

The correct answer is mesoderm.

Explanation:

A germ layer is a layer of cells that forms during embryo development. In triploblastic animals, there are three layers. Mesoderm between ectoderm and endoderm two layers, forming triploblastic. Germ layers give rise to all tissues and organs by the process of organogenesis.

Mesoderm give rise to muscles, cartilage, bone, heart, connective tissue, adipose tissue, lymphatic system, circulatory system, dermis, genitourinary system, notochord, and serous membranes.

Thus, the correct answer is mesoderm.

Which factor most likely caused animals and plants in India to differ greatly from species in nearby southeast Asia?
Dominik [7]

Answer:

India was a separate continent until 45 million years ago

Explanation:

India was part of the Gondwanaland continent which was one of the two remnants of Pangaea, while Asia was part of Laurasia, the other remnant of Pangaea. Because these two land masses were separate, the animals and plants were evolving separately for millions of years. India further separated from Gondwanaland, and it was actually a very large island for millions of years, resulting in isolation and development of unique animals and plants because of it. As India was moving it reached Asia and collided with it, thus becoming one land mass. Some Asian species managed to get in India, but mostly in its northern parts, while the central and southern parts remained dominated by the indigenous species. The Himalayan Mountain Range that formed because of the collision also helped in preserving lot of the indigenous species as it became a natural barrier that most species can not go through.

What is the order of the cell cycle
DerKrebs [107]

Answer:

A in explanation

Explanation: The cell cycle is a four-stage process in which the cell increases in size (gap 1, or G1, stage), copies its DNA (synthesis, or S, stage), prepares to divide (gap 2, or G2, stage), and divides (mitosis, or M, stage). The stages G1, S, and G2 make up interphase, which accounts for the span between cell divisions.

Why does genetic diversity help keep a species healthy?
GalinKa [24]
