What is the phenotype of a plant with the genotype RR?
Red
White
O
Pink
Answer:
This question is incomplete, but it can be answered based on general knowledge of the topic. The answer is RED
Explanation:
This question is describing a gene that codes for color. The allele for red color is R while that of white is r, however, these two alleles exhibit incomplete dominance to form an intermediate phenotype that is PINK (Rr).
Since the heterozygous is pink color, it will take two red alleles to make a plant phenotypically red i.e RR. Note that, genotype "rr" will be white.

If the object is falling under the influence of gravity alone, this is called?
Answer: gravitational energy
Explanation: If you have a book on a table and it might fall, its using gravitational energy because its depending on gravity to choose rather it will fall or just balance. It also depends on how high the object is off the ground

Explanation:
A wavelength with a frequency of 14 HZ has a wavelength of 3 meters at what speed will this wave travel
Answer:
The speed will be 42 m/s
Explanation:
Wavelength is the minimum distance between two points on the wave that are in the same state of vibration. In other words, in a periodic wave the wavelength is the physical distance between two points from which the wave repeats.
Frequency (f) is the measure of the number of cycles or repetitions of the wave per unit of time. That is, it is the number of vibrations that occur in a unit of time. That is, how many peaks or valleys are repeated in a unit of time. If the unit of time is one second then the frequency is measured in Hertz (Hz).
The wavelength (λ) and the frequency (f) are two inversely proportional parameters and related by the propagation speed. The speed of propagation is the speed with which the wave travels, it is represented by the letter "v". The equation that links these three parameters is v = f * λ.
In this case:
f= 14 Hzλ= 3 mReplacing:
v= 14 Hz* 3 m
Solving:
v= 42 m/s
The speed will be 42 m/s

Answer:
1. Covalent Bond
2. Ionic Bond
Explanation:
Covalent bonds are defined as the bond in which sharing of electrons takes place between atoms. The sharing of electrons is in equal number so that it form a stable balance of attraction and repulsion between atoms. In the given example of CO2 (first image) oxygen is sharing equal number of electrons with carbon to form a stable bond called covalent bond.
Ionic bonds are formed when valence electrons are transferred to other atoms and form oppositely charged ions. In ionic bond formation, the atoms that gain electrons become negatively charged and the atoms that loses electrons become positively charged. In the given example of Ca Cl2, Ca is also giving its 2 valence electrons to each Cl and there is no stable balance of attraction and repulsion between atoms.
Hence, the correct answer is:
1. Covalent Bond
2. Ionic Bond
0.6 sample an unknown organic acid found in muscle cells is burned in air and found to contain 0.24g of carbon, 0.04g of hydrogen with the rest being oxygen. If the molecular weight of the substance is 90g/mol what is the emperical and molecular formula
Answer:
Molecular formula is, C₃H₆O₃
Empirical formula (with the lowest subscript) → CH₂O
Explanation:
We assume that the organic acid's mass is 0.6 g. We know that, in 0.6 g of compound we have 0.24 g of C and 0.04 g of H, then, we have
(0.6 - 0.24 - 0.04) = 0.32 g of O.
We determine each mol:
0.24 g /12 g/mol = 0.02 mol of C
0.04 g/ 1g/mol = 0.04 mol of H
0.32 g/ 16 g/mol = 0.02 mol of O
1 mol of acid weighs 90 g/mol.
In 0.6 g of acid, we have, (0.6 g / 90g/mol) = 0.0067 moles
Let's find out the formula with rules of three:
0.00667 mol of acid have 0.02 moles of C
1 mol of acid may have (0.02 /0.00667) = 3 mol of C
0.00667 mol of acid have 0.04 moles of H
1 mol of acid may have (0.04 /0.00667) = 6 mol of H
0.00667 mol of acid have 0.02 moles of O
1 mol of acid may have (0.02 /0.00667) = 3 mol of O
Molecular formula is, C₃H₆O₃
We confirm by the molar mass: 12g/mol . 3 + 6 . 1g/mol + 32g/mol . 3 = 90
Empirical formula (with the lowest subscript) → CH₂O
What enzymes Break it down sugar ???
What was Rutherford's model of the atom missing?
Answer:
The Rutherford atomic model stated that an atom is mostly an empty space that consist of nucleus and electrons, where nucleus is positively charged and electrons are negatively charged.
But Rutherford atomic model missed to add the quantum mechanics or energy level for electrons. Rutherford was unable to make understand the planetary movement of electrons around nucleus and later Bohr's model explained it.
Hence, Rutherford's model of the atom missed to explain the planetary movement of electrons around nucleus.
In metallic bonds, electrons are referred to as electrons.
Answer:
Metallic bonding may be described as the sharing of free electrons among a lattice of positively charged metal ions. The structure of metallic bonds is very different from that of covalent and ionic bonds. ... In metallic bonds, the valence electrons from the s and p orbitals of the interacting metal atoms delocalize.

Imagine a group of hunters kills half of the rabbit population. How will it affect the other organisms?
Answer:
They will die off too
Explanation:
The animals that feed off the rabbits will start to die off from starvation, and so will the animals tho eat off of those. The entire food chain above the rabbits will start to decrease, while the plants and animals that the rabbits eat will increase in population due to less predators.
