Answer:
The equation to this question is unclear. The clear equation is:
CH4 + 2O2 → CO2 + 2H2O
Please find the number of atoms of each element on the reactant and product side below.
Explanation:
An atom is the smallest indivisible part of an element. The atom retains the chemical properties of the chemical element. In order to ensure that a chemical reaction between molecules and compounds is BALANCED, the number of atoms of each element that makes up the molecule/compound must be the same on both the reactants and products side.
In this case, the chemical reaction involves:
CH4 + 2O2 → CO2 + 2H2O
1. Carbon atom (C):
Reactants side = 1 atom
Products side = 1 atom
2. Oxygen atom (O):
Reactants side = 4 atoms
Products side = 4 atoms
3. Hydrogen atom (H):
Reactants side = 4 atoms
Products side = 4 atoms
Stuart is listing the changes to matter and energy that occur during the process of photosynthesis. Which of these examples should he include in his list?
A. nuclear changes that convert hydrogen and oxygen into carbon
B. chemical changes that convert carbohydrates into smaller molecules
C. changes that convert light energy into chemical energy stored in carbohydrates
D. changes that convert chemical energy into heat and light
Answer:
C. Changes that convert light energy into chemical energy stored in carbohydrates
Explanation:
Just had this question on a bio assignment.
Photosynthesis occurs in plants containing chlorophyll in which the solar energy entrapped is converted into the chemical fuel needed for energy generation.
The correct answer is:
Option C. Changes that convert light energy into chemical energy stored in carbohydrates.
This can be explained as:
The leaves of plants capture the rays and with the help of water and carbon dioxide create glucose and oxygen.The nourishment or the nutrient includes carbohydrates that get broken in the presence of solar energy and experience chemical changes.Therefore, during photosynthesis light energy is transformed into chemical power.

What is the best explanation for the faster times of the group fed a pre-race meal of bread with bananas and honey
Answer:
Bread, bananas and honey have carbohydrates.
Explanation:
The group fed a pre-race meal of bread with bananas and honey because bread, bananas and honey have high amount of carbohydrates which give quick energy to the athlete. This carbohydrate is a macromolecule which is quickly converted into micromolecule i. e. glucose that is absorbed by the cell and the mitochondria of the cell produces energy in the form of ATP that is used by the athlete in running.

classify the following materials as rock or mineral
Answer:
You did not provide us with the materials you need to be classified, but I hope this helps:
A mineral is a solid formation that occurs naturally in the earth while a rock is a solid combination of more than one mineral formations which is also occurring naturally. A mineral has a unique chemical composition and is necessarily defined by its crystalline structure and shape.
Examples of rocks include: sandstone, basalt, limestone, and slate
Examples of minerals include: cobalt, zinc, lithium, and gold
Describe the movement of the water molecules at hot temperatures.
Answer:
Temperature causes water molecules to move more quickly, because each individual molecule has more energy as it gets hotter (according to Kinetic molecular theory). If you get water hot enough, the molecules move so much that the hydrogen bonds that hold them together start to break and the water becomes a gas

Which bar graph best represents the equatorial diameters of the eight planets of our solar system?
Answer: The First one/ A /Top Left corner
Explanation:
Equatorial distance shows the size of a planet. The larger the distance, the larger the planet.
Option A puts Jupiter as having the largest distance which is correct as Jupiter is the largest planet and is followed by Saturn and then Uranus and Neptune in that order.
Option A also shows Earth as being larger than Mars, Venus and Mercury which is accurate as well.
Option A is the best choice.
The part of the plant where you would find the most cellulose is ? ( dont say cell walls , im looking where at
a-leaves
b-roots
c-branch
d-stem
Answer:
d-stem
Explanation:
Cellulose is most abundant in meristems tissues which are present in the tips of the root and stem and in the cambium between the xylem and the phloem and under the epidermis of the trees and shrubs, therefore it is abundant in the stems.
Meristems are also found in other parts of the plant but it is mostly abundant in the stems.
Meristems are the cells that are responsible for the cell growth and elongation.

When a red flowered pea plant was crossed with a white flowered pea plant, it was found that all plants in the F1generation carried only red flowers. If these plants are self crossed, i) Find the genotypic ratio that we can expect in F2 generation ii) What is the phenotype and genotype of F1 generation. Draw Punnett square for F2
Answer:
The correct answer is -
i) genotype of F2 - 1:2:1 = dominant:heterozygous:recessive
ii) genotype of F1 - all heterozygous dominant
phenotype - all red
Explanation:
In the cross of red- flowered plant and white flowered plant the offspring produces red flowers that s only possible if the parent red flower plant has both alleles in dominant condition.
For the F1 the gametes will be R, R and r, r
from the Punnett square, we can see all the offspring are heterozygous (Rr) in genotype and red in phenotype
For F2 the gametes will be - R, r, and R, r
From the punnet square, the genotype we get is 1:2:1 = dominant:heterozygous:recessive

2
24
Answer:243
Explanation: multiply all of them then add and it will be 243
The expression that is equivalent to a - 4 is: (a - 2) - 2 or (a - 6) + 2 or (a - 4) + 0 or (a - 8) + 4.
What is an expression?An expression in mathematics is a set of variables, constants, and operators that can be evaluated to produce a value.
For example, the expression "2x + 3" contains the variable x, the constants 2 and 3, and the operators + and *.
When we substitute a value for x, such as x = 4, we can evaluate the expression to get a value, in this case 11.
The expression that is basically equivalent to a - 4 is:
(a - 2) - 2 or (a - 6) + 2 or (a - 4) + 0 or (a - 8) + 4.
For example,
If a = 6, then a - 4 = 6 - 4 = 2, and we can also write it as (6 - 2) - 2 or (6 - 6) + 2 or (6 - 4) + 0 or (6 - 8) + 4. All of these expressions simplify to 2.
Thus, this can be the expression asked.

Which of the following explains why a breeding-soundness examination is performed?
to determine the age of the animal
to determine what traits will be passed on to offspring
to determine what genes were inherited from parents
to determine the likelihood of fertility
Answer:b
Explanation:
The statement to determine what traits will be passed on to offspring explains the breeding-soundness examination is performed.
What do you mean by breeding soundness examination?The breeding soundness examination (BSE) involves a complete and systematic evaluation of the reproductive potential of a given male, including mating ability and libido, general physical examination.
The breeding soundness exam (BSE) is much more than a “semen test.” It consists of a physical exam that should include examination of the eyes, feet and legs, teeth (if an older bull), and general overall condition.
By following out breeding system i.e., crossbreeding, selective breeding and grading up according to the need, results in improvement in production performance of the crossbred.
