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.

Drag and drop the steps of digestion to order them from first to last step.
Saliva rushes into the mouth and mixes with the broken-down food.
The food travels down the esophagus.
The muscles of the stomach churn the food and continue to break it down.
The teeth in the mouth bite off a piece of food. The teeth continue to break the food into smaller pieces.
The broken-down food, called chyme, enters the small intestine.
The remaining food passes into the large intestine. Water is absorbed from the large intestine and the rest of
the material is stored as solid waste until it is excreted from the body.

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.

after fertilization a single cell divides successfully to form a multicellular structure what happens next in order for this structure to develop tissues and organs to meet the needs of the organism
Answer:
After fertilization, a single cell divides successfully to form a multicellular structure. What happens next in order for this structure to develop tissues and organs to meet the needs of the organism? The cells undergo differentiation into particular body parts.
A multicellular organism develops from a single cell (the zygote) into a collection of many different cell types, organized into tissues and organs. Development involves cell division, body axis formation, tissue and organ development, and cell differentiation (gaining a final cell type identity).

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.

We don't breathe in carbon we breathe in oxygen and breathe out carbon.
Photosynthesis only happens in plants.
Carbon dioxide is a gas and you can't eat it.
Answer: The correct answer is B They gain carbon by eating it.
Explanation: When animals eat food, they are ingesting carbon in the form of carbohydrates and proteins. In addition, plants produce carbon during photosynthesis for plant growth. When animals eat the plants, they ingest carbon from those plants as well.

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!

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.
