- Question
During the sensorimotor stage the main task is to
- Correct Answer
- Jean Piaget was a cognitive psychologist who identified four stages of development: the sensorimotor stage from birth to 2 years, the preoperational stage from age 2 to age 7, the concrete operational stage from age 7 to 11, and the formal operational stage from age 11 to adult He identified milestones that occur at each stage According to Piaget, the main task of the sensorimotor stage is for the child to learn the concept of object permanence, use senses and motor skills to understand the world

Correct Answer: mitochondrion
Explanation:
Cellular respiration is best associated with the organelle Mitochondrion.
Correct Answer: Protista
Explanation:
The Amoebas belong to a group called Protista.
Amoebas are of the animal kingdom subdivision for microscopic organisms - protozoa.
Correct Answer: Reproductive glands
Explanation:
Endocrine glands are glands of the endocrine system that secrete their products, hormones, directly into the blood rather than through a duct.
The major glands of the endocrine system include:
pineal gland,
pituitary gland,
pancreas,
ovaries,
testes,
thyroid gland,
parathyroid gland,
hypothalamus and
adrenal glands.
Correct Answer: Cervicitis
Explanation:
Leukorrhea is a thick, whitish or yellowish vaginal discharge. There are many causes of leukorrhea, the usual one being estrogen imbalance. The amount of discharge may increase due to vaginal infection or STDs, and it may disappear and reappear from time to time. This discharge can keep occurring for years, in which case it becomes more yellow and foul-smelling. It is usually a non-pathological symptom secondary to inflammatory conditions of vagina or cervix.
Correct Answer: mitochodria
Explanation:
Cellular repiration takes place in the mitochodria.
There are 3 phases of cellular respiration. They are:
1. Glycolysis (Fermentation),
2. Krebs Cycle, and
3. Electron Transport.
Glycolysis takes place in the cytoplasm. The Krebs cycle and electron transport takes place in the mitochondria.
Correct Answer: Cytoplasm
Explanation:
Right after that, the mRNA enters the cytoplasm through nuclear pores. There, it could be translated into proteins by ribosomes. This process is called translation.
Translation occurs in the cytoplasm whereas transcription occurs in the nucleus.
Correct Answer: DNA information is copied to RNA
Correct Answer: Myelinated
Explanation:
A myelinated nerve can be found int the brain or spinal cord as well as the peripheral nervous system, it is white and is surrounded by schwann cells or oligodendrocytes.
Correct Answer: Synaptic cleft
Explanation:
A neuron or nerve cell is a cell that carries electrical impulses. Neurons are the basic units of the nervous system and its most important part is the brain. Every neuron is made of a cell body (also called a soma), dendrites and an axon. Dendrites and axons are nerve fibres.
The gap between two communicating neurons is termed Synaptic cleft.
Correct Answer: Proteins
Explanation:
Enzymes are protein macromolecules. Enzymes are almost always made of proteins only. Proteins are large biopolymer molecules that are made up of repeating monomer units called amino acids. There are 20 different common amino acids that make up proteins like enzymes. Of these, nine amino acids are essential, which means you must get them from your diet.
Enzymes catalyze chemical reactions in biological systems. This means that they speed up the rate of the reaction.
