How does fertilization affect the chromosome number of a zygote?
Answer:
Fertilization is the fusion of gametes to form the zygote. ... Fertilization allows restoring of the chromosome number of the species as the two nuclei of gametes fuse together. Therefore, the number of chromosomes in the zygote is twice the number of chromosomes in gametes.

How do cells obtain energy?
Answer:
Beginning with energy sources obtained from their environment in the form of sunlight and organic food molecules, eukaryotic cells make energy-rich molecules like ATP and NADH via energy pathways including photosynthesis, glycolysis, the citric acid cycle, and oxidative phosphorylation.
Cells have an organelle known as 'mitochondria' which has ATP molecules in it. These ATP molecules generates energy for the cell to function properly.
Cells need a source of energy, they get this energy by breaking down food molecules to release, the stored chemical energy.
This process is called 'cellular respiration'.
The process is happens in all the cells in our body.
Oxygen is used to oxidize food, main oxidized food is sugar(glucose).

How can a material at a certain temperature have all of its molecules at the same energy?
Answer:
A material at a certain temperature does not have all of its particles at the same energy. ... Just because we can assign a single number to the temperature of an object that is in thermal equilibrium does not mean that every atom of the material is moving with the same energy because of the nature of averaging. hope this helps

10
20
Please help!!
Answer:
10
Explanation:
Your body can't produce the ten necessary amino acids and must acquire them from your diet.
The body does not manufacture essential amino acids and must be supplied by food. They don't need to take one meal at a time. The equilibrium is more significant during the day.
The body produces nonessential amino acids from essential amino acids or from the natural degradation of proteins.

Explanation:
its fairly simple if a medicine, antibiotic in this case is not changed over time then the thing it is fighting will learn how to ignore it to where it no longer works as the species adapt and change the antibiotics must to otherwise there will be no effect.
Many years ago, scientists working with cells developed what is now known as the cell theory. The cell theory states: – All living things are composed of one or more cells. – Cells are the basic units of structure and function in an organism. – Cells come only from the reproduction of existing cells. Which of the following observations best supports the cell theory?
Cells come in a variety of shapes and sizes.
Cells have different names for different structures.
Cells can live a very short time.
Cells from animals only create other animal cells.
Which three organs are part of the digestive tract?
A) salivary glands, gall bladder, appendix
B)teeth, tongue, mouth
C)esophagus, stomach, small intestine
D)esophagus, liver, pancreas
Answer:
C
Explanation:
Due to the stomach and small intestine being part of the digestive tract and the esophagus allowing food, liquids and air to enter the torso
Esophagus, stomach, small intestine are part of the digestive tract. Therefore option C is correct.
The digestive tract, also known as the gastrointestinal tract, is responsible for the process of digestion in the human body. It consists of a series of organs that work together to break down food and absorb nutrients.
The three organs that are part of the digestive tract are the esophagus, stomach, and small intestine.
The esophagus is a muscular tube that connects the mouth to the stomach and helps in the transportation of food. The stomach is a sac-like organ that mixes and churns food with digestive enzymes and acids.
The small intestine is a long tube where the majority of digestion and absorption of nutrients occurs.
Therefore option C esophagus, stomach, small intestine is correct.

PLS HELP!!! I'LL GIVE BRAINLY!!!
Answer:
See the answer below
Explanation:
First, let us look at the complete equation of respiration:
[tex]C_6H_1_2O_6 + 6O_2 -->6CO_2 + 6H_2O[/tex]
The respective number of each atom in the reactants and the products can be filled in the table thus:
Types of atom Number of atom in reactants Number of atom in products
Carbon 6 6
Hydrogen 12 12
Oxygen 18 18
The total number of each atom in the reactants is equal to the total number in the products. Hence, the calculation confirms the law of conservation of matter that says that matters can neither be created nor destroyed, but can be converted from one form to another in a course of a reaction.
