In humans, the gene for a free earlobe (E) is dominant over the gene for an attached earlobe (e). If one parent has a free earlobe (Ee) and the other parent has an attached earlobe (ee), what is the probability that their offspring will have an attached earlobe?
A- 0%
B- 25%
C- 50%
D- 100%
Answer:
C- 50%
Explanation:
If you draw a Punnett square, you can see the chances of the offspring's genotype (the various E/e combinations)
E x e (parent 1)
e E e e e
e E e e e
^( parent 2)
There is a 50% chance of having E e and 50% chance of having e e. Since attached earlobes are recessive, there is then a 50% chance that the offspring will have e e.

Soil: The unconsolidated mineral or organic material on the earth's immediate surface, which is used to grow soil plants Soils top limit lies in the boundary of soil and air, shallow water, live plants, or non-disintegrating plant materials.
Minerals: A mineral is an inorganic solid with a natural occurrence, a certain chemical composition, and an orderly atomic structure.It gets simpler if you break it down. Naturally, minerals are present. They're not made by people.
Soil Particle Size: Particle sizes are either determined by the capacity for various mesh sieves, or by the rate at which they are placed in water.
Soil Profile: The soil profile is a vertical soil section and enables you to investigate the soil structure.
O-horizon: are layers of soil with a high organic matter percentage. There are typically three different organic layers within the forests: one of leaves, pine needles and branches (Oi); underlined by a partially decomposed layer (Oe); and a very dark layer of decomposed humus (Oa).
A-horizon: contains deposits of organic matter leached from surface soils
B-horizon: a ground level below the horizon from which organic matter is obtained by illuviation, and which normally stands out by a reduced weathering, is directly below the horizon.

in a greenhouse you can control the temperature, light intensity, and carbon dioxide level in order to make it the what factor in photosynthesis
Answer:
Limiting factor
Explanation:
A limiting factor is simply anything in short supply that prevents a reaction from occurring at its maximum rate.
In a greenhouse you can control the temperature, light intensity, and carbon dioxide level which are the limiting factors in photosynthesis for the production of glucose.
What is limiting factor?A limiting factor is a variable that produce a change in output of a process or a chemical reaction. Every process has its limiting factors which bring a change in it.
So we can conclude that temperature, light intensity, and carbon dioxide level which are the limiting factors in photosynthesis.

Monosaccharides and amino acids are both monomers. These monomers are formed by
hydrolysis. Which statement correctly identifies a difference in the structure of
monosaccharides and amino acids? *
A)Only amino acids contain cytosine, adenine, guanine, and thymine,
B)Only amino acids join together with peptide bonds to form proteins.
C)Only monosaccharides contain carbon and hydrogen.
Answer:
B: only amino acids join together with peptide bonds to form proteins.
Amino acids are glycine and leucine, which are composed of carbon, hydrogen, oxygen, and nitrogen. Carbon, hydrogen, and oxygen make up carbohydrates, which can be either little or big molecules, hence option B is correct.
What is the difference between monosaccharides and amino acids?
The building blocks that makeup proteins are polymeric molecules made up of a chain of amino acids. The biological role of galactose, mannose, fructose and ribose is also significant.
The most prevalent monosaccharide in living things is glucose, which also serves as a structural support system and an enzyme to catalyze chemical processes.
Therefore, the amino group of the additional amino acid creates a peptide bond with the polymer's carboxylic acid group, hence option B is correct.

Humans affect Earth in many ways. The use of fossil fuels, the clear-cutting of forests, and controlled burns can affect the carbon cycle. Which process can help counteract these human interactions? photosynthesis respiration decomposition transpiration
Answer:
Photosynthesis
Explanation:
Photosynthesis takes in CO2 from the atmosphere and utilizes it to form sugars/oxygen.
The equation: 6CO2+6H2O -> C6H12O6 + O2
Respiration will do the opposite and actually release CO2 into the atmosphere
Decomposition will also release CO2 as a byproduct
Transpiration I don't believe has anything to do with removing or putting CO2 into the atmosphere. It's about water movement!
Answer:
The answer is A) Photosynthesis!

-Chromosomes are found in sets of three.
5. Which modification affects an organism’s expressed characteristics while leaving its DNA sequence unchanged?(1 point)
-insertion mutation
-substitution mutation
-deletion mutation
-epigenetic change
Answer:
100% correct if you use the answers below :)
Explanation:
1. AGC TTT CG
2. CCA TAA CT
3. deletion
4. Chromosomes contain DNA
5. epigenetic change
A frameshift mutation involves the insertion or deletion of nucleotides in a DNA sequence, which modifies its open reading frame. A deletion is a mutation that involves the elimination of one nucleotide in DNA sequence.
With regard to the questions above described:
1. The sequence AGC TTT CG suffered a deletion of the Adenine (A) base at the second codon (i.e., AGC TTA TCG).2. The sequence CCA TAG CT exhibits a deletion of the Cytosine (C) base at the first codon (i.e., CCC ATA GCT).3. Cystic fibrosis is a recessive inherited disorder caused by a three-nucleotide (codon) deletion in the CF transmembrane conductance regulator (CFTR) gene. This deletion is associated with the loss of phenylalanine (Phe) amino acid in the exon 10 of the CFTR gene.4. The statement 'chromosomes contain DNA' is TRUE. Chromosomes are thread-like structures that contain part or all of the genetic material (DNA) of an organism.5. Epigenetic changes are modifications that affect an organism’s phenotype while leaving its DNA sequence. Epigenetic modifications include DNA methylation and histone modifications (e.g., histone acetylation, histone methylation).In conclusion, frameshift mutations involve the modification of the Open Reading Frame. Deletion involves the elimination of a nucleotide in DNA. Chromosomes are thread-like structures that contain genetic material. Epigenetic modifications don't modify the genetic (nucleotide) sequence.

C. water changes pH as it warms.
D. overfishing is changing the structure of ecosystems, haring the plankton that regulate the pH of ocean water.
E. acid rain has worsened over the last two decades.
Answer: b
Explanation:
Its b because Ocean acidification is occurring because excess carbon dioxide (CO2) in the atmosphere is being absorbed at the surface of the ocean at an increasing rate. This excess CO2 results in more hydrogen ions, which increases the acidity of the ocean.
