Endocrine & Nervous System
It refers to the body’s abilities to maintain constant internal equilibrium by adjusting its physiological process.
Homeostasis
It produces the sperm
Testes/Testicles
A single stranded piece of a DNA has the following bases: ACT-GAG-CTA-GTC-ATG. What is the matching sequence on its mRNA?
UGA-CUC-GAU-CAG-UAC
It refers to the process where organisms possess adaptive characteristics to have a better chance to survive and reproduce.
Natural Selection
It refers to the number of organisms per unit area.
Population density
It helps control growth, reproduction and body temperature.
Hypothalamus
It secretes thick fluid that contains nutrients for the sperm.
Seminal vesicle
What are the compositions of the DNA molecule?
5-carbon deoxyribose sugar, phosphate group, one of the nitrogenous bases (Adenine, Thymine, Guanine, Cytosine)
These are preserved remains of once-living organism.
Fossils
It refers to the factors where the population’s density does not directly influence changes in population’s growth.
Density-independent limiting factors
When you eat, there is an increase of sugar level in your body. What hormone is responsible for regulating the amount of sugar level in your body?
Insulin
Name two hormones which is responsible for the normal development of the organs of the male reproductive system.
Testosterone and Androgen
What are the pyrimidines found in RNA?
Uracil (U) and Cytosine (C)
It refers to the structures from different species which have similar internal framework, position, and embryonic development.
Homologous Structures
What limiting factors is shown in the situation below:
Dinoflagellates in Laguna de Bay increase in population due to increase in organic substance in the body of water brought by water pollution.
Resources
It refers to the mechanism which dominates in times of stress.
Sympathetic Mechanism
A tiny fingerlike projection where the egg passes from the ovaries to the uterus.
Fallopian tube
What are the three main differences between DNA and RNA?
DNA is double-stranded while RNA is single-stranded.
The sugar for DNA is deoxyribose while for RNA is ribose.
Nitrogenous bases in DNA: Adenine - Thymine, Cytosine - Guanine
Nitrogenous bases in RNA: Adenine - Uracil, Cytosine - Guanine
Example of this structure are wings of birds, bats, and insects - they have the same function but different in origin.
Analogous Structures
It refers to a period of rapid growth. During this period, there are plenty of resources available for all organisms, so more births are recorded than deaths in organisms.
Exponential Growth
It refers to the process where the endocrine glands send information back and forth within itself in order to control or regulate the amount of hormones it produces.
Negative Feedback Mechanism
It is the phase where the surface of the endometrium begins to disintegrate and blood vessels would rupture.
Menstrual Phase
DNA: ATG-TAT-ACG
mRNA:
tRNA:
Amino acid:
mRNA: UAC-AUA-UGC
tRNA: AUG-UAU-ACG
Amino acid: tyrosine - isoleucine - cysteine
Feces, bones, footprints, skin impression, eggs in nest
It refers to a period of limited resources. In this period, population expansion decreases as resources become scarce, and it levels off when the carrying capacity of the environment is reached.
Logistic growth
