The answer is tuna and leatherbacks
Answer:
This question lacks options, the options are:
A. Only recessive alleles are inherited from homozygous parents.
B. Dominant alleles grow weaker as they are passed from parents to offspring.
C. Only the parent with a dominant allele can pass that allele to offspring in sexual reproduction.
D. A heterozygous parent has an equal chance of passing either the dominant allele or the recessive allele to offspring.
The answer is D
Explanation:
This question involves a single gene coding for hair length in dogs. The allele for short hair (S) is dominant over the allele for long hair (s). This means that allele 'S' will always mask the phenotypic expression of allele 's' in a heterozygous state.
According to the question, two heterozygous dogs (Ss) were crossed to produce 6 shortt-haired offsprings and 2 long-haired offsprings. An heterozygous organism is that which contains two different alleles for a particular gene i.e. a combination of dominant and recessive alleles.
Based on this, during meiosis or gamete formation, an heterozygous dog (Ss) will produce gametes with the short hair allele (S) and long hair allele (s) in equal proportion i.e. 50-50. When the two gametes containing the recessive alleles (s) produced by each heterozygous parent fuses, an offspring with a recessive phenotype (long hair, ss) is produced.
Hence, a long-hair
phenotype can appear in the offspring of two short-haired dogs because a heterozygous parent has equal chance of passing either the dominant or recessive allele to the offspring.
Answer:
A) effect of sugar on a metabolic activity of yeast
Explanation:
In this experiment, everything was kept the same except for adding sugar into one test tube and none on the other. The data that was recorded was the bubble formation. Bubble formation is an indicator for a chemical reaction and in this case it is the metabolic activity of the yeast.
Everything that is kept constant like the amount of yeast suspension, temperature and time it was placed in the warm water bath are what we call controlled variables. This is done to prevent any other variables from affecting what is being tested.
The amount of sugar is what is different and this is called the independent variable. This is what we are testing to see if it will have an effect.
Finally, bubble formation or metabolic activity is the dependent variable. This is what will be observed as a result of the changes in the independent variable.
There are two main processes of glacial erosion<span>. The first is plucking, which is defined as the </span>erosion<span> and transport of large chunks of rocks. As a </span>glacier<span> moves over the landscape, water melts below the </span>glacier<span> and seeps into cracks within the underlying bedrock.</span>
All of those systems are vital for a person to survive. If an organ stopped functioning it could cause you to die unless it is your liver and a few others.
