Being able to curl your tongue is a recessive trait (t), while not being able to curl your tongue is a dominant trait (T).
Having curly hair is also a recessive trait (s), while having straight hair is a dominant trait (S).
Parent 1 can curl their tongue (tt) and also has straight hair (Ss). Parent 2 cannot curl their tongue (TT) and has
curly hair (ss). In your notebook, perform a dihybrid cross for these traits. Parent 1: ttSs Parent 2: TTSS

___________________is the rate that an object moves in a certain direction. Question 3 options:
Speed
Displacement
Direction
Velocity
Answer: Velocity
Explanation:
i just took the quiz for k12
Velocity is the rate at that an object moves in a certain direction. The correct option is d.
What is velocity?The directional speed of an item in motion, as measured by a specific unit of time and observed from a certain point of reference, is what is referred to as velocity. A vector is a velocity. It comprises both magnitude and direction.
The size of velocity is speed. In still air, a particle gravitationally settles and quickly reaches its terminal velocity. The term "settling velocity" refers to a particle's final speed in a still fluid (also known as the "sedimentation velocity").
The particle settling velocity in the foreshore region plays a significant role in understanding fluctuations in the hydraulic regime and interactions between sediment and fluid in the surf zone.
Therefore, the correct option is d, Velocity.

Solid iron pellets are heated, melted and drawn into wires. This is an example of a chemical reaction
True
False
Answer:
false
Explanation:
It is a physical reaction because it is being heated.
Answer:
False
Explanation:
Just because the iron was melted into wires does not mean that it isn't iron. It is still iron just in a different form.
Plz help how do I predict the shape of the molecule for GaBr3
Explanation:
GaBr3 is called gallium tribromide. It is composed of one gallium atom and three bromide atoms. Within a molecule of gallium tribormide, there are three bonding electron pairs and zero lone pairs of electrons. Such a configuration results in the trigonal planar molecular shape.

Sand is composed of silicon dioxide SiO2. A 210 gram sample has how many moles?
The number of moles of 210 gram sample of sand contains 3.5 moles of mole of SiO₂
Sand is composed of silicon dioxide (SiO₂).
Therefore, let's calculate the molecular mass of SiO₂ . Therefore,
Molecular mass of SiO₂The molecular mass of the compound is the sum of the atomic mass of the compound.
SiO₂ = 32 + (16 × 2) = 28 + 32 = 60 g/molTherefore,
60 g = 1 mole of SiO₂
210 g = ?
cross multiply
number of moles = 210 / 60
number of moles = 21 / 6
number of moles = 3.5 moles

Which of the following is the smaller atom: magnesium or chlorine?
Answer:
Chlorine atoms are smaller
Explanation:
Magnesium have more electrons than chlorine.
Answer: Chlorine
Explanation: Since chlorine's 17 protons are greater than magnesium's 12 protons, chlorine will have a greater effective nuclear charge to draw chlorine's valence electrons closer to the nucleus and, thus, chlorine is expected to have the smaller atomic radius, while magnesium with the lower effective nuclear charge is expected to have the larger atomic radius.
