There are three main types of memory: sensory, short-term and long-term memory.
Base sequence on one strand of a DNA molecule
AAT GCC AGT GGT
Complementary strand produced when the DNA strand is replicated
TTACGGTCACCA
The reproductive system is responsible for the production of sperm or egg cells and fertilization. Both male and female reproductive organs are regulated by hormones.
Hormones do not target mutations during fertilization.
Events leading to childbirth
1. Stretching of the uterus triggers a release of oxytocin
2. Baby's head pressing against the cervix triggers more oxytocin
3. Mother is in full labor
Body regulation and feedback present in the situation
Positive feedback
Main functions of the female reproductive system
Produces female sex cells
Receives sperm cells
Nourish the new individual
Statements true about menstruation
Involves the shedding of the lining of the uterus
Usually last for 3 – 9 days and is accompanied by menstrual cramps
Hormones such as estrogen and progesterone are produced by the ovaries
The body does not become dehydrated when body temperature rises.
Cause of sickle cell anemia
An inherited blood disorder where red blood cells (RBCs) become sickle/crescent shaped. It affects the shape of red blood cells, which carry oxygen to all parts of the body.
Onset of menstruation
Menarche
A child learning to walk on his own does not show the process of adaptation.
Pathway of the sperm to fertilize the egg cell
Vagina → cervix → uterus → fallopian tube
1st day of last menstruation
Mar 8
Possible date of the next menstruation if the cycle lasts for 28 days
April 5
Hormones that cause FSH and LH to be released
Gonadotrophin-releasing hormone
Father of evolution
Charles Darwin
Another name for natural selection
Survival of the fittest
Correct example of homologous structures
Fingers of human and arm of starfish
Flipper of whale and forelimb of cat
Steps of protein synthesis in correct order
II-I-IV-III-VI-V
Fertilization occurs in the fallopian tube while implantation happens in the uterus.
Reason why organisms with close biochemical similarities show stronger evolutionary relationships
They have a common ancestor and have the same kind of proteins.
Building block of protein
Amino acids
Theory of Natural Selection
In nature, the organisms with desirable characteristics may survive while those with weaker traits may not.
Hormone produced in the ovary before ovulation
Estrogen
Difference between positive and negative feedback
Negative feedback reverses changes in a system, while positive feedback amplifies changes in a system.
Hormone that causes Leydig cells to make testosterone
LH
Correct order of hormones produced during the monthly cycle
FSH, estrogen, LH, progesterone
Start codon
AUG
Hormones that signal ovulation
LH
Chromosome mutation where a piece of a chromosome breaks off and attaches to a different, non-homologous chromosome
Translocation
Class of mutation where only 1 gene is affected
Point mutation
The amino acid sequence of DNA with a sequence AAT CGG CTG GGA TTA is Leucine – Alanine – Aspartic Acid – Serine – Asparagine.
Rocks in which fossils can be found
Sedimentary
Building blocks of a nucleotide
Base
Deoxyribose
Phosphate
Key players of the DNA replication that build up the complementary strand
DNA Polymerase
Type of mutation that results in the sickle-cell disease phenotype
Non-conservative missense mutation
Group of 3 nucleotide sequences for an amino acid
Codon
Chromosomal aberration also known as Down syndrome
