Answer:
See the answer below
Explanation:
Genotype is the genetic composition of organisms and a gene is made up of two alleles.
a) Since the allele for black is B, the genotype for black chickens would be BB.
b) Since the allele for white is W, the genotype for white chickens would be WW.
c) Since erminette color is heterozygous, the genotype would be BW.
d) Two erminette were crossed:
BW x BW
BB BW BW WW
i. Probability of having black chick (BB) = 1/4
ii. Probability of having a white chick (WW) = 1/4
iii. Probability of having erminette chicken (BW) = 1/2

Are there always going to be an EQUAL number of guanine and cytosine molecules in a molecule of DNA? Why?
Answer: Yes
Explanation:
Yes, because guanine can only pair with cytosine, according to Chargaff's Rule.
As altitude increases, air pressure __________ (increases, decreases, or stays the same). This is a(n) ________(direct, indirect, of static) relationship. PLEASE HELP :)
Answer:
The correct answer is - decreases. direct.
Explanation:
Altitude is a distance measurement of distance in a vertical manner or how high something from the sea level. It helps in the height of the mountains and different places.
Air pressure and altitude are the two factors that are in direct relation as the air pressure decreases with the increase in altitude. the gases present in the higher elevations are fewer than the sea level.

a. Carbon dioxide and water are the reactants of both processes.
b. Carbon dioxide and water are the products of both processes.
c. Carbon dioxide is a reactant of photosynthesis; water is a reactant of cellular
respiration.
d. Carbon dioxide and water are the reactants of photosynthesis and the
products of cellular respiration.
Answer:
d. Carbon dioxide and water are the reactants of photosynthesis and the
products of cellular respiration.
Explanation:
Photosynthesis turns CO2 and water into oxygen and glucose. Plant foods are glucose and oxygen is a by-product. glucose.
Cellular breathing turns oxygen and glucose into carbon dioxide and water.
Water and carbon dioxide are byproducts, while ATP is
process-transformed energy.

2. Once the solution across a membrane does in fact reach equilibrium, the molecules in solution will
A. move across the membrane to the outside of the cell.
B. completely stop moving across the membrane.
C. continue to move across the membrane in both directions.
D. move across the membrane to the inside of the cell.
Answer:
B
Explanation:
Molecules and ions diffuse through cell membrane due to a concentration gradient. But, once the equilibrium is achieved between inside and outside the cell, molecules stop moving. Thus, option B is correct.
What is cell membrane?Cell membrane is an organelle surrounding the cell which facilitates the transportation of ions and molecules, inside and outside the cell. To maintain an ionic balance is important in metabolism of living things.
Ions such as sodium and potassium are balanced by a mechanism called sodium -potassium pump. The sodium ions outside the cell is greater than that of inside.
Similarly calcium pump works for calcium and magnesium. The concentration gradient of these ions make this flow of ions across cell membrane. Hence, once they achieve equilibrium the flow will stop and no ions will be transported across the membrane.

Amino acids have similar structures. What part of an amino acid's molecular formula distinguishes the macromolecule from other amino acids?
O the R-group
o the amino group
o the carboxyl group
O the nitrogenous base W
Answer:
The R-group
Explanation:
Amino acids are organic compounds that combine to form proteins. There are 20 of them, out of which 9 are essential. All of them have a similar structure: they consist of an alpha (α) carbon atom bonded to an amino group (NH2), a carboxyl group (COOH), a hydrogen atom, and an R group. The R group is the organic component, a side chain, that is unique to each amino acid.
This is why the first option is the correct one.

What structure do plant cells have during cytokinesis that animal cells do not have?
Answer:
During cytokinesis in animal cells, a ring of actin filaments forms at the metaphase plate. The ring contracts, forming a cleavage furrow, which divides the cell in two. In plant cells, Golgi vesicles coalesce at the former metaphase plate, forming a phragmoplast.

What are amphibians?Amphibians are animals with vertebral columns that live on land and in water. Their skin is permeable, allowing them to breathe and respire. They are also cold-blooded and have a complicated life cycle.
Different from reptiles, amphibians lay unshelled eggs in the water. The eggs lack a soft and hard shell covering, but are protected from drying out by a jelly-like material.
Amphibians are four-legged creatures that can live on both land and water. The majority of amphibians deposit their eggs in water.
Therefore, the correct option is B. lungs, which help it take in oxygen from the air and four legs.

Does adding or taking away a proton change the identity of the element? Yes or no
Answer:
yes
Explanation:
The identity of an element is determined by the number of protons. One cannot alter the number of protons without altering the identity of the element. By adding a proton, the atomic number increases by one and the element identity changes. Number of neutrons can be altered to create isotopes.
Answer:
Yes
Explanation:
Protons carry a positive electrical charge and they alone determine the charge of the nucleus. Adding or removing protons from the nucleus changes the charge of the nucleus and changes that atom's atomic number. So, adding or removing protons from the nucleus changes what element that atom is!
How do molecules in the cells of the body release energy
Chemical energy is stored in the bonds of sugars. When the bonds of a sugar molecule are broken, a burst of energy is released that the cell can use. Cells can release energy in two basic processes: cellular respiration and fermentation.
Through the production of ATP, the energy which is derived from the breakdown of sugars and fats is redistributed in the cell as packets of chemical energy in a convenient form for use elsewhere.
How do cells release energy?All cells have energy to do work whereas glucose and other sugars have cell food. Almost all of these contain a source of energy for cell activities. When glucose is stored as glycogen or taken up as starch, it must be broken down into individual molecules before cells are able to to use it.
Chemical energy is stored in the bonds of sugars. When these bonds of a sugar molecule are broken, there is an explosion of energy which can be used by the cell.
These cells can release energy in two basic processes which are cellular respiration and fermentation. Oxygen is needed for cellular respiration, but not for fermentation. Furthermore, cellular respiration releases a lot of usable energy compared to fermentation.
Thus, through the production of ATP, the energy which is derived from the breakdown of sugars and fats is redistributed in the cell as packets of chemical energy in a convenient form for use elsewhere.

Fruit production in anthophytes develops from: a. a female reproductive structure b. a male reproductive structure c. both male and female reproductive structures d. photosynthetic signals
Answer:
a. a female reproductive structure
Explanation:
Reproduction can be defined as a biological process which typically involves living organisms producing an offspring.
Basically, there are two (2) methods of reproduction and these are;
I. Sexual reproduction: it involves the combination of the genome (gamete) of a male and female living organism during fertilization.
II. Asexual reproduction: it involves the cloning of a living organism to produce an offspring because there is only a single parent.
Antophyte is the division name for flowering plants and they are considered to be the most successful of all the other division of plants in terms of reproduction.
Division Antophyta are classified into two (2) main categories and these includes;
I. Monocot: this group of flowering plants have a single cotyledon. Some examples of monocots are lilies, corns, grasses etc.
II. Dicot: this group of flowering plants have two cotyledon. Some examples of dicots are beans, peas, peanuts, etc.
Basically, fruit production in anthophytes develops from female reproductive structure known as the ovary. Once the ovary is fertilized by a sperm, they ripen into a fruit.
