the answer is a black hole
The universe immediately before the Big Bang occurred as a black hole. Thus, the correct option is A.
What is the Big bang?The big bang may be defined as the cosmic explosion that significantly marked the initiation of the universe according to the big bang theory. The origin of the universe is explained by the Big Bang theory.
At initial, the whole universe appeared like a black hole where no life is present. It was all the dark around each and every corner. The universe was an infinite stretch of ultrahot, dense material and everything consisted of empty space.
Before the big bang, the universe was almost infinitely small, dark, and a size less than a trillionth of a second. It was a period of inflation which is followed by a more catastrophic event which was violent, and known as the period of expansion.
Therefore, the universe immediately before the Big Bang occurred as a black hole. Thus, the correct option is A.

Question 12 options:
How many tall plants resulted from Mendel's cross
How many yellow plants resulted from Mendel's cross
Color of seeds Mendel chose to cross
Height of plants Mendel chose to cross
Answer:
Color of seeds Mendel chose to cross
Explanation:
This variable does not depend on the other variables you are trying to measure, so it is independent.
In Gregor Mendel cross, the variable does not depend on the other variables you are trying to measure, so it is independent.
What is Gregor Mendel cross?Mendelian Crosses: In one of his experiments on inheritance patterns, Mendel crossed plants that were true-breeding for violet flower color with plants true-breeding for white flower color (the P generation).
Mendel first experimented with just one characteristic of a pea plant at a time. He began with flower color and cross-pollinated purple- and white-flowered parent plants. He was surprised by the results. This led to his law of segregation.
A dihybrid cross is a breeding experiment between two organisms which are identical hybrids for two traits. In other words, a dihybrid cross is a cross between two organisms, with both being heterozygous for two different traits.

What happens during meiosis I? *
a. Chromosomes line up in pairs, separate, forming haploid cells
b. Chromosomes line up in pairs, separate, forming diploid cells
c. Chromosomes line up single file, separate, forming haploid cells
d. Chromosomes line up single file, separate, forming diploid cells
Answer:
What is c. Chromosomes line up single file, separate, forming haploid cells
In meiosis I, chromosomes in a diploid cell resegregate, producing four haploid daughter cells. It is this step in meiosis that generates genetic diversity. DNA replication precedes the start of meiosis I. During prophase I, homologous chromosomes pair and form synapses, a step unique to meiosis.

What is another way nitrogen is added back into the atmosphere BESIDES animal waste, but is too unreliable to count on?
Answer:
Plant and animal wastes decompose, adding nitrogen to the soil. Bacteria in the soil convert those forms of nitrogen into forms plants can use. Plants use the nitrogen in the soil to grow. People and animals eat the plants; then animal and plant residues return nitrogen to the soil again, completing the cycle.
Respond to the following based on your reading.
1. Name the three common states of matter on earth.
2. Which states of matter have a set shape? Explain why this is, based on the
а
animations you observed for the different states of matter.
3. Which states of matter have a set volume? Explain why this is, based on the
animations you observed for the different states of matter.
4. The boiling point is the temperature at which a liquid substance will turn to
vapor, and also the temperature at which vapor will condense to a liquid. The
a
boiling point of ethanol is about 80°C, and the boiling point of water is about
100°C.
a. What can you conclude about the intermolecular forces in water and
ethanol?
b. Do you predict water freezes at a higher temperature or at a lower
temperature than ethanol?
5. Recall how different Van der Waals attractions and how ionic charges changed
the movement of atoms in the animation. Do you think that Van der Waals
attractions or ionic charges are stronger? Why?
Answer:
Most people are familiar with three states of matter – solids, liquids and gases – but there are two more that are less commonly known but just as important – plasmas and Bose-Einstein condensates. They are very compressible (particles are widely spaced). There are three states of matter: solid; liquid and gas. They have different properties, which can be explained by looking at the arrangement of their particles.
atoms
An atom is the smallest particle of an element, having the same chemical properties as the bulk element. The first accurate theory explaining the nature of matter was Dalton's Atomic Theory: 1. All matter is composed of atoms, and atoms are indivisible and indestructible.
What are the 8 states of matter?
Bose–Einstein condensate.
Fermionic condensate.
Degenerate matter.
Quantum Hall.
Rydberg matter.
Rydberg polaron.
Strange matter.
Superfluid
Answer:
1. Liquid, Solid, Gas
2. Solid has a set shape. Solid can move but gas and liquid is more flexible than solid.
3. Solid has a fixed volume while liquid and gas takes the volume of its container. Solid stays in one place while gas and liquid are flexible.
4. A. The stronger the intermolecular forces in a liquid the higher the boiling point. Therefore, water has a stronger intermolecular force than ethanol.
B. Water molecules are more attracted to each other than ethanol (alcohol) molecules, because water has more hydrogen atoms bonded to oxygen. ... So, that's why alcohol has a much lower freezing point
5. Ionic charges are stronger.
Covalent bonds are known to have the strongest and most stable bonds since they go deep and into the inter-molecular state. A diamond is an example of a compound with this characteristic bond.
Ionic bonds are the next strongest molecular bond following covalent bonds. This is due to the protons and electrons causing an electro-static force which results to the strong bonds. An example would be Sodium Chloride (NaCl), which when separated is Na⁺ and Cl⁻.
Van der Waals forces, also known as Dispersion forces, are the weakest type of molecular bonds. They are only formed through residual molecular attractions when molecules pass by each other. It doesn't even last long due to the uneven electron dispersion. It can be made stronger by adding more electrons in the molecule. This kind of molecular bonds appear in non-polar molecules such as carbon dioxide.

why do stem get modified give any three examples and explain how this notification help the plant
Answer:
underground stem -- for storage of food ex. potato , ginger.
spines for protection ex. citrus , bougainvillea
Explanation:
Rhizomes and corms are underground stems, modified for the storage of food. Also, these stems help in vegetative reproduction of these plants. The tips of the underground stem in potato plants become swollen due to the accumulation of food. The potato is a tuber that helps in the storage of food and bears eyes on it.

You have a friend who became stranded in a blizzard without food for
several weeks. This friend, when rescued, had lost about 7 kg (about 15
Ibs). As he was quite healthy to begin with, he assumed the weight he
lost was stored fat, but he wondered where the fat had gone, How did
the fat leave his body?
The fat didn't really leave his body. Fat was converted to glucose in the gluconeogenesis pathway to give him energy during the period of starvation.
Fat is stored in the body in the adipose tissue. Fat plays so many roles in the body such as;
Protection of vital organsInsulating the body from coldServing as an energy storeIn times of starvation, fact could also be broken down to release energy. This occurs when fat is broken down to glycerol and fatty acids. When this occurs, glycerol goes to the liver where it is converted to glucose in the gluconeogenesis pathway. This helps to produce energy in times of starvation thereby depleting the body's fat reserve.
As this process occurs, the fat reserve in my friend's body kept going down resulting in his loss of about 15 Ibs of weight.
