Answer:

Double fertilization produces a diploid sporophyte and a triploid endosperm. (Ans. C)

Explanation:

Angiosperm are plants which is known for flowering plant on the earth. The flower is reproductive parts of the angiosperm plant. They are including 4 basic parts of the flower: Carpel, Stamens, Sepals and Petals.

During angiosperm plant reproduction, 2 structure are formed which are known as the Endosperm and a Zygote. Later a Zygote will grow and form a embryo and the endosperm is known for food source of plant embryo. Endosperm and Zygote forming process is known as double fertilization and it is a unique process found in angiosperms.

Steps involved in double fertilization are:

1) The pollen tube processing to release 2 sperm cells into an unfertilized ovule.

2) When one sperm cell fuses with the eggs to the formation of zygote and another sperm fuses with the 2 polar nuclei to the formation of endosperm this process is known as double fertilization.

3) After the completion of double fertilization, a fruit and seed develop.

What is the last phase of the Cell Cycle? (This is when the genetic material has already been duplicated and what is left to do
Marianna [84]

Answer: mitotic phase

Explanation:

The cell cycle has two phases the Interphase and mitosis. Interphase is the growth phase where the cell prepares itself for the cell division. It is divided into three phase G1 phase( Cell growth),S phase ( DNA synthesis) and G2 phase(cell growth).

Mitotic phase has a multiple steps this is where the duplicated chromosomes are aligned or arranged, separated, and move into two new, identical daughter cells(cytokinesis)

The first step in the mitotic phase is called karyokinesis or nuclear division where the chromosomes are separated and move in opposite direction and the second portion of the mitotic phase, called cytokinesis which is the physical separation of the chromatids into the two daughter cells.

Answer:

The correct answer is: C.

Explanation:

  • The given situation is the example of a Reflex Action.
  • Reflex action can be defined as an action shown in response to a sudden stimulus.
  • The CNS or the Central Nervous System is comprised of the Brain and the Spinal Cord which receives the Sensory impulses from the Receptor organ, integrates or decides on the response which needs to be provided and then sends the Response impulses to the Effector organ.
  • The PNS or the Peripheral Nervous System is comprised of the sensory and motor neurons those are responsible for connecting the Sensory organ and the Motor organ to the CNS, respectively.
  • In the situation, Sarah's eyes perceives the ball and sends sensory impulses through the optic nerve containing the sensory neurons (PNS) to the spinal cord.
  • The spinal cord possess inter-neurons (CNS) that decides over the action to be done in response to the stimulus.
  • The Response stimulus is send from the inter-neurons via the motor neurons (PNS) to the eye muscles of Sarah and Sarah performs the action, that is, she blinks.
