During pregnancy after fertilization, the embryo gets implanted in the uterine wall. So the correct option is D.

The embryo is the stage of an animal's early development when it is within an egg or a mother's uterus. When referring to an unborn person, the phrase is used up to the end of the seventh week after conception; starting with the eighth week, the term "fetus" is used.

When an ovum and a sperm unite to form a sexually reproducing organism, the outcome is a zygote, or fertilized egg, which goes through a series of divisions known as cleavages as it travels down the fallopian tube. A hollow ball known as a blastula is created by the cells following many cleavages.

In most animals, the blastula adheres to the uterine lining, causing the placenta to develop and begin supplying the developing fetus with nourishment from the mother. The yolk feeds the embryo in lower animals.

The embryo differentiates into three types of tissue through the process of gastrulation: the ectoderm, which produces the skin and nervous system; the mesoderm, from which connective tissues, the circulatory system, muscles, and bones develop; and the endoderm, which produces the digestive system, lungs, and urinary system.

Therefore the correct option is D.

Explanation:

Red Blood Cells Carry Blood Away from the heart to the rest of your body/organs

Blood is taken to the lungs to become oxygenated and returned to the heart before being pumped through the body by the blood vessel called  arteries.

Blood vessels are the networks of hollow tubes which involve in the transportation of blood throughout the entire body along with the delivery of nutrients.  

The blood vessel Arteries are elastic in nature which transport blood away from the heart Like Pulmonary arteries transport the blood from the heart to the lungs.

Veins are elastic transport blood to the heart. There are four types of veins are pulmonary, systemic, superficial, and deep veins.

Capillaries present within the tissues of the body and transport blood from the arteries to the veins.

Sinusoids a narrow vessels present within the liver, spleen, and bone marrow, deliver blood from larger arteries to veins.

The organelles in the plant cell that are shown in the image are: A: Chloroplast, B: Vacuole, C: Cell wall and D: Endoplasmic reticulum.

A: Chloroplast - This organelle is responsible for photosynthesis, the process by which plants convert sunlight into energy and produce glucose. Chloroplasts contain chlorophyll, a pigment that captures light energy.

B: Vacuole - The vacuole is a membrane-bound sac filled with fluid, primarily containing water and various dissolved substances. It plays a role in storing nutrients, waste products, and maintaining turgor pressure in plant cells.

C: Cell Wall - The cell wall is a rigid outer layer found in plant cells, bacteria, fungi, and some protists. It provides structural support and protection for the cell, helping maintain its shape and integrity.

D: Endoplasmic Reticulum (ER) - This organelle is involved in the synthesis, folding, modification, and transport of proteins and lipids. It can be rough (with ribosomes on its surface) or smooth (lacking ribosomes). The rough ER is involved in protein synthesis and modification.

Answer:

the object pushing back on you

Explanation:

i put b in my test and it was wrong

and did it again and got it right

According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.

The answer would be:
