Semester 2 exam 2024 Flashcards
11 AG SCI
What is Ethylene
Ripening of fruit, release of dormancy, stimulates shoot root growth, Stimulates leaf abscission.
.001, h+, ph 3 t/f ?
True- .001 1 over 10x10x10
10 to the power of negative 3 (-3) = pH 3 h+ irons
What is Cytokines
Controls major growth periods of the plant linked to ethylene to control obsession flowers/ leaved fruit
What is the Stigma
Female part of slower top of pollen receptacles become style leads to ovary
What is the Pistil
Femail colective petles of flowers
What is the Arthur/Filament
Pollen producers stamen
What is Photosynthesis
6 CO2 + 6H2O ——–> C6 H12 O6 + 6O2
What is Structure soil
Percentage sand, silk, clay
What is Nitrogen
Macro - involved in cell function diction, protein synthesis, photosynthesis transfer of energy
Whats is Epigeal Germination
Cotyledons pushed above soul line until photosynthesis provided energy for the plant by itself.
What is Habitability
P=G+E
30% Genetics
70% environment
What is Sperm morphology
Motility
LDR
Amount of sperm
Quality of the sperm
Any dis functions
What is Environment / management
Can influence phenotype. Eg: supplementary flooding, temperature, vaccination, irrigation and windbreak.
What is Protein
Crude
NPN
What is Temperature a big influence on
Gonadotrophin released controlled by hypothalamus
Name the key player in ruminant and protein digestion.
These cud-chewing mammals have four chambers of stomachs used for their digestion. These species obtain their nutrition from plant products by adapting to a certain process called rumination.
Explain the influence is the anatomy of a mono gastric ?
Monogastric digestive systems begin with the in- gestation of food into their mouth. The tongue and the teeth gather feed and break it down into smaller pieces in order to make it easier for the animal to digest. Food travels down the oesophagus, which is a long tube that carries the feed from the mouth to the stomach.
The rum-en is a fermentation tank: Explain the design / operation of this tank?
The rumen, a crucial part of the digestive system of ruminant animals such as cows, sheep, and goats, acts as a natural fermentation tank. Understanding its design and operation provides insight into how these animals efficiently digest fibrous plant materials
Na HCO3
NaHCO₃, commonly known as sodium bicarbonate or baking soda
The “ Bomb callory defficate
A bomb calorimeter is a device used to measure the heat of combustion of a particular reaction
Protein digestion
When protein is digested it is broken down into peptides which then become NH4+ and NH3-
2 types of protien are ?
Crude and NPN
NPN is?
Non protein digestion
Rumen microbes
Major source of protein in a bovines diet, breaks down CP NPN to NH4+ NH3-
Microbes role
Break down protein . Continuously flushes from the rumen to omasum to abomasium are then absorbed.
Calories/kilojoules
Formula: Multiply the energy value by 4.184
N fixation refers to
N2 Gas fixed to an available form converted to NH3-
Ice-cream form refers to what ?
N
NO2
NH4+
NO3-
Recitations consists of ?
AIR 78%N
Rain consists N
Ammonification is?
N is present in the soil but in a complex form / toed to organic matter and compounds
Notrosamanus and nitrobacter are…?
Bactria responsible
Denitrification
waterlogged soils
