Answer:

Earth formed around 4.54 billion years ago, approximately one-third the age of the universe, by accretion from the solar nebula. Volcanic outgassing probably created the primordial atmosphere and then the ocean, but the early atmosphere contained almost no oxygen.

How do the properties of water contribute to transpiration
muminat

Answer:

Cohesion and adhesion of water molecules

Explanation:

Cohesion has to do with the ability of water to adhere together .

The cohesive properties of water which is occasioned by hydrogen bonding between adjacent water molecules allow the column of water to move up through the plant irrespective of the force of gravity as water molecules are evaporating at the leaf surface.

The adhesive properties of water, which means, the attraction between the water molecule and the xylem wall also ensure continuity in the movement of the water column in the xylem.

Hence the cohesive and adhesive properties of water molecules are important for transpiration to occur.

-describe the 3 steps of embryonic development (cleavage division, gastrulation, organogenesis)
julsineya [31]

Answer:

Cleavage, in embryology, in the first few cell divisions of the zygote. Initially, the zygote separates into the longitudinal axis. The second division is also longitudinal but at 90 degrees on the first plane. The process produces a multicellular embryo. It is an assembling process that divides the seed into developmental regions. Zygote cytoplasm includes chemicals that control gene expression.

Gastrulation is characterized as an early embryonic phase in which the embryo is converted from a one-dimensional layer of epithelial cells to a multilayer, multidimensional structure called the gastrula.

Organogenesis is a process of embryonic development that occurs at the end of gastrulation and lasts until birth. During organogenesis, the three germ layers formed by gastrulation (ectoderm, endoderm, and mesoderm) form the internal organs.
