Cells move to new positions as an embryo establishes its three germ tissue layers during option(d) i.e, gastrulation.
A young developmental process known as gastrulation occurs when an embryo changes from a one-dimensional layer of epithelial cells (blastula) to a multilayered, multidimensional structure known as the gastrula.
The three embryonic germ layers—the endoderm, ectoderm, and mesoderm—are positioned during gastrulation. Later, these layers grow into specific body systems. The three layers of embryonic tissue, or germ layers, are created as a result of gastrulation. These cells will multiply, move, and differentiate during development into the four main tissues: epithelial tissue, connective tissue, muscle tissue, and nerve tissue.

Answer:
The chair is made of abiotic factors, such as plastic or wood that needed to be chopped down, and is thus dead. I am alive because I have living organisms and organs that help my body function and keep me alive.
<span>There are two
types of modern wind turbines. In a Verical-axis wind turbines (VAWTs), the
shaft is mounted on a vertical axis perpendicular to the ground. They are
aligned with the wind so there’s no adjustment necessary when the wind
direction changes. It can’t start moving on itself that is why it needs a boost
from its electrical system to get started. It uses wires for support so the
rotor elevation is lower. They are less efficient than HAWTs due to its lower
elevation. Lower elevation means slower wind due to ground interferences. The
other type is Horizontal-axis wind turbines (HAWTs), the shaft s mounted
horizontally parallel to the ground. It is constantly aligned with the wind
using a yaw-adjustment mechanism. This mechanism moves the entire rotor left or
right in small increments. It uses a tower to lift the turbine components to an
optimum elevation for wind speed and take up very little ground space. It is
much more efficient than VAWT. The motion that converts into electricity is the
rotor. The answer is letter D.</span>
Alanine and Serine
<span>The degradation of amino acid is to transform
the carbon skeleton into metabolic intermediates that can be easily be oxidized
by the citric acid cycle or converted into glucose. Both Alanine and serine
provide substrate for ketone bodies gluconeogenesis. However, metabolism of
alanine yields pyruvate directly by transamination</span>
Uhhhhh what’s the question
