Having freckles (F) is dominant over not having freckles (f). A parent with freckles is crossed with a parent without freckles. The Punnett square shows the possible genotypes of the offspring.
What is the genotype of each square?
A: FF Ff ff
B: FF Ff ff
C: FF Ff ff
D: FF Ff ff
Answers
Answer:
A: Ff
B: ff
C: Ff
D: ff
Explanation:
You basically look at the box it's asking for, let's use A as an example. On the top where the A column is there's F, so that's one of the thingys I forgot what they're called. Next look at the row of A, and there's f. Put the 2 together and you get Ff. Reminder that any uppercase ones come first.
A=Ff
B=ff
C=Ff
D=ff

Answers
According to the concept of specific heat capacity, the heat capacity of water is 1666.67 J/Kg°C.
What is specific heat capacity?Specific heat capacity is defined as the amount of energy required to raise the temperature of one gram of substance by one degree Celsius. It has units of calories or joules per gram per degree Celsius.
It varies with temperature and is different for each state of matter. Water in the liquid form has the highest specific heat capacity among all common substances .Specific heat capacity of a substance is infinite as it undergoes phase transition ,it is highest for gases and can rise if the gas is allowed to expand.
It is given by the formula ,
Q=mcΔT
Substitution of values in the above equation, c=30000/0.3×(85-25)
c=1666.67 J/kg°C
Thus, the heat capacity of water is 1666.67 J/Kg°C.

Answers
Answer:
1) 157 Neutrons, 2) the decimal is simply is due to isotopes, because the elements atomic mass is an average of these isotopes multiplied by its abundance(or percentage on earth.) For Mercury, it has many isotopes(an element with a different mass number, logically the atomic mass listed on the periodic table as a mass has 100% abundance, therefore this is used to find the most abundant mass for that particular element/molar mass) likewise, Mercury has an atomic mass of 200.59 u, as one mol of Hg(mercury) is 200.59 grams.

C.) Sunlight is used to help release waste produce such as oxygen in plants.
D.) Plants need sunlight to help capture carbon dioxide to create sugars and starches.
Answers
Answer:
D
Explanation:
They make their own food by combining a gas called carbon dioxide, which they get from the air, with water from the soil. ... To power the process, the plant uses the energy of sunlight. A green pigment in the leaves called chlorophyll traps the Sun's energy

Answers
Answer:
19 protons, 19 electrons, and 3 neutrons
Explanation:
the atomic number is 19 so the protons are the same, 19, and the electrons are the same as the proton, because protons are positive and electrons are negative so they have to balance out and the neutrons ➗ mass number by the atomic number.

An atom's nucleus contains three protons and three neutrons. What is the overall charge of the nucleus?
O A. O
O B. -3
O C. +3
O D. +6
Answers
Explanation: Protons have positive charge, electrons have negative charge, and neutrons have no charge. Therefore, having three protons and 3 neutrons would give you a net +3 charge.
Hope this helps!
The statement, that describes the overall charge of the nucleus is "+3."
What is nucleus?The atom is made up of a small nucleus surrounded by electrons that move. The nucleus is a positively charged area in the centre of the atom that is made up of closely packed protons and neutrons.
The nucleus includes protons, which have a positive charge equal to the negative charge of an electron. Neutrons, which have nearly the same mass but no charge as protons, may also be found in the nucleus.
The nucleus is made up of three neutrons and three protons. Neutrons have no charge. The charge on the nucleus results from the charge on its protons. As a result, the total charge of the nucleus is +3.
Hence the correct answer is C.

Hammer orchids are plants with flowers that are highly modified to resemble a female thynnid wasp (i.e., a wasp of the Thynnidae family) and can only be pollinated by thynnid wasps. Female thynnid wasps cannot fly, but males can. When the female is prepared to mate, she will climb up a tall plant or a blade of grass and wait for a male to appear. Males will pick up the female from her perch and mate with her in flight.
Given this information, in three to five sentences, describe these details:

The carbon cycle is the rotation of the carbon and its compound in the atmosphere. carbon is added to the atmosphere by burning fossils and is a waste product of respiration. Thus, options C and D are correct.
What is a carbon cycle?A carbon cycle is a biogeochemical cycle that involves the reuse of the carbon from various sources that involve the atmosphere and organisms. The cycle repeats itself again and again.
When fossil fuel is burnt carbon dioxide along with some gases are released into the atmosphere. Also, carbon dioxide is a waste product of cellular respiration. Most of the carbon is present in rocks, oceans, and the atmosphere.

which of these pairs of atoms are isotopes
A: scandium-46, titanium-46
B: iron-56, sodium-24
C: chlorine-35, chlorine-37
D: sodium-24, magnesium-24
Answers
Taking into account the definition of isotopes, the correct answer is option C: chlorine-35, chlorine-37
First of all, all atoms are composed of a central nucleus in which there are positively charged particles, the protons, and neutrally charged particles, the neutrons, around which other negatively charged particles that are electrons move.
That is, atoms are made up of a nucleus (made up of protons and neutrons) and a shell made up of electrons.
On the other side, isotopes are atoms whose atomic nuclei have the same number of protons but different numbers of neutrons.
The atomic number (Z) indicates the total number of protons in the nucleus of a given atom, while the atomic mass (A) is obtained by adding the number of protons and neutrons in a given nucleus.
So, in other words, each isotope of the same element has the same atomic number (Z) but each has a different mass number (A). This means that the different isotopes of the same atom differ from each other only by the number of neutrons. So if a neutron is added to an atom, it becomes an isotope of that chemical element.
So, in this case, the correct answer is option C: chlorine-35, chlorine-37, because the two chlorine atoms correspond to the same element but have different atomic masses, whose values are 35 and 37.
