Answer:
Explanation:
Species
A group of organisms that can reproduce and produce fertile offspring (children that can reproduce themselves)
Trait
Characteristic of an organism (body part, behavior, chemical, produced)
Variation
Differences in trait expression
Inherited trait
Trait passed from parent to children (offspring)
Acquired Trait
Traits learned by/changed in an individual from interaction with the environment
Protein
A special type of biological molecule (only found in organisms) that organisms use to build, maintain, and operate the cells/tissues/organs of their bodies. (Like a prepared meal)
DNA
The biological molecule that serves as the chemical instructions or blueprints for building all the proteins an organism needs to build its body and survive. (Like words in a cookbook)
Gene
A section of a DNA molecule that serves as the instructions to build one protein. (Like one recipe in a cookbook)
Chromosomes
Large packages of coiled DNA molecules that are passed from parents to children. (Like different chapters on a cookbook)
Pollen
Flowering plant sperm (male sex cell)

Explanation:
Hypo-eutectoid steel has less than 0,8% of C in its composition.
It is composed by pearlite and α-ferrite, whereas Hyper-eutectoid steel has between 0.8% and 2% of C, composed by pearlite and cementite.
Ferrite has a higher tensile strength than cementite but cementite is harder.
Considering that hypoeutectoid steel contains ferrite at grain boundaries and pearlite inside grains whereas hypereutectoid steel contains a higher amount of cementite, the following properties are obtainable:
Hypo-eutectoid steel has higher yield strength than Hyper-eutectoid steel
Hypo-eutectoid steel is more ductile than Hyper-eutectoid steel
Hyper-eutectoid steel is harder than Hyper-eutectoid steel
Hypo-eutectoid steel has more tensile strength than Hyper-eutectoid steel.
When making a knife or axe blade, I would choose Hyper-eutectoid steel alloy because
1. It is harder
2. It has low cost
3. It is lighter
When making a die to press powders or stamp a softer metals, I will choose hypo-eutectoid steel alloy because
1. It is ductile
2. It has high tensile strength
3. It is durable

Explanation:
The transportation sector is the highest contributing factor to greenhouse gas emissions in the world. Vehicles such as cars, motorcycles, airplanes, ships etc all emit these gases which causes global warming.
Electric cars is known not to little or zero direct emission and known to be safer. It however emits nitrogen oxide which is fog like in a very minute quantity.
A good visual lead is 20-30 seconds from the front of the vehicle, focusing in the center of the path of travel. Searching 20 to 30 seconds ahead, gives you time to assess within the next ..12-15 seconds, actions you may need to take to control an approaching risk.
Discussion:
Keeping eye focus centered in a path of travel at an interval of 20 to 30 seconds away from the vehicle is critical to gaining enough info. as possible in the driving scene. Good targeting sets up good sight lines for referencing and good peripheral fields for observing changes.
- It is important to look ahead 12-15 seconds into your target area as one drives. Compromise. space by giving as much space to the greater of two hazards.
