Answer:

The correct answer will be- zygote →cleavage→ morula→ blastula→ gastrula.

Explanation:

Human embryogenesis is the study of the formation of an embryo from the zygote formed after the fertilization of the sperm and egg cell.

The fertilization takes place in the ovarian duct in females which form a diploid zygote. The zygote starts the process of cleavage that is cell division and differentiation and leads to the formation of a 2 celled stage, 4 celled stages and later 16 celled stage. The 16 celled stage  is known as morula which further undergoes cleavage and form blastula. The blastula now forms a gastrula with 3 layered distinction- the ectoderm, endoderm and mesoderm through gastrulation.

Thus, zygote →cleavage→ morula→ blastula→ gastrula is the correct answer.

Elanso [62]

Answer:

The correct answer is myofibrils

Explanation:

The fundamental part of the muscle cytoskeleton is made up of myofibrils that are the contractile elements of skeletal muscle cells.Muscle fibers are made up of myofibrils, membranes, and cytoskeletal networks that anchor contractile fibrils to the sarcolemma. Myofibrils are composed of repeating contractile units known as sarcomeres and are perhaps the most ordered macromolecular structures in eukaryotic cells. Myofibrils are made up of actin and myosin filaments that are large polymerized protein molecules responsible for actual muscle contraction.

What method would you use to divide organisms into groups, or classes, based on specific characteristics?
romanna [79]
Biological Classification.
The classification system starts with a group with a wide variety of organisms and becoming more selective as the groups get more specific.
Additional information: Carl Linnaeus classified organisms by shared characteristics.

Energy moves in the form of energized.......?
insens350 [35]
 <span>Actually energy is the capacity to do work. It is not moving. It is transmitted, propagated, dissippated, or radiated. It depends upon what type of energy it is. Heat energy is dissippated through conduction, convection or radiation. For conduction the particles must be in contact. For convection the particles which posses the energy must ba able to move about. For radiation, even without a material medium the energy is transmitted in the form of waves. Eg. energy from the sun. When a stone is dropped in still water the energy is imparted to the water surface. This energy is distributed all over the water surface in the form of circular waves (ripples). Electrical energy - through conducting wires or electromagnetic radiation. Light energy & sound energy are through waves.</span>

Which two processes does this diagram most directly models?
svet-max [94.6K]

The correct answer is D. Homeostasis and transport of molecules

Explanation:

The diagram presented shows the movement of glucose from outside the cell to inside it. Also, this diagram illustrates this process occurs through the cell membrane and there is a higher concentration outside the cell.

This complex process illustrates the transport of molecules in the cell, which refers to a mechanism that allows molecules and substances to move in and out of a cell. Moreover, this process implies molecules (in this case glucose) move to one area with a lower concentration to preserve equilibrium as shown by the diagram. Additionally, this equilibrium is part of homeostasis which is a set of mechanisms to main an equilibrium in the cell, including appropriate levels of glucose and other substances.

In fruit flies, one genotype for red eyes is written XRXR. The R stands for the dominant allele for red eyes. What does the X st
Reil [10]

Answer:

The correct answer is : the female chromosome

Explanation:

  • According to the question, it is mentioned that R is a dominant allele, responsible for the red eyes.
  • RR is a genotype for Red eyes.
  • A fruitfly has a diploid genotype which means each trait is represented by a pair of chromosomes.
  • In the above question, the dominant red eye colour trait is represented by the pair of chromosomes RR.
  • Therefore, XX must represent another trait.
  • By convention, a pair of X chromosomes (XX) represent a female and a combination of X and Y chromosomes (XY) represents a male.
  • Given XX genotype represent a female fruitfly chromosome.
