Сотраге and contrast Simple Dominance to Incomplete Dominance."
Answer:
Simple dominance is when the dominant gene in a heterozygous organism expresses the dominant phenotype. Incomplete dominance is when a heterozygous organism exhibits a blending of both genes, recessive and dominant. Red and white flowers will "blend" and make pink flowers.
Incomplete dominance, only one allele in the genotype is seen in the phenotype. In simple dominance, both alleles in the genotype are seen in the phenotype. In incomplete dominance, a mixture of the alleles in the genotype is seen in the phenotype.

As a genetic counselor, you advise couples about the possibility of genetic disease in their offspring. This morning you met with an engaged couple, both of whom are phenotypically normal. The man, however, has a brother who died of Duchenne-type muscular dystrophy, an X-linked condition that results in death before the age of 20. The allele responsible for this disease is recessive. His fiancee, whose family has no history of the disease, is worried that the couple's sons or daughters might be afflicted.
Requied:
a. How would you advise this couple?
b. The sister of this man is planning to marry his fiancée's brother. How would you advise this second couple?
Answer:
a. This couple should not worry.
b. This couple should worry.
Explanation:
a. The man should not be worried. This is because he is normal (phenotypically).
b. They should be worried because the sister of the man can be a carrier of the recessive allele. If she was a carrier, then half of their male children can be affected.

How is the energy of chemical processes coupled in metabolic pathways?
Answer:
Energetic coupling of chemical processes in metabolic pathways Biochemical systems couple energetically unfavorable reactions with energetically favorable reactions. These reactions can be part of catabolic pathways where complex substances are broken into simpler ones with the release of energy or anabolic pathways where complex molecules are synthesized with an input of energy.
Explanation:
During transcription, initiation involves the attachment of RNA polymerase to the promoter and the start of RNA synthesis.
Group of answer choices
True
False
Answer:
true
Explanation:
True. During transcription, initiation is the first step in which RNA polymerase binds to the promoter region of the DNA molecule.
The promoter is a specific sequence of nucleotides located upstream of the gene that signals the start site for transcription. RNA polymerase recognizes and binds to the promoter sequence, forming a complex called the transcription initiation complex.
Once the transcription initiation complex is formed, RNA synthesis begins. RNA polymerase unwinds the DNA double helix in the region of the gene, exposing the template strand. It then catalyzes the synthesis of an RNA molecule by adding complementary RNA nucleotides to the growing RNA chain according to the base pairing rules (A-U and G-C).
So, the statement "During transcription, initiation involves the attachment of RNA polymerase to the promoter and the start of RNA synthesis" is true. Initiation is indeed the process where RNA polymerase binds to the promoter and initiates the synthesis of an RNA molecule based on the DNA template. This is a crucial step in the process of transcription, as it determines where and when the transcription of a specific gene will occur.

Mitosis is the division of the _____ and begins with a stage called ____ . As the nuclear envelope finishes dissolving, the cells enter ____, where microtubules from the spindle attach to the duplicated X-shaped chromosomes.
When all chromosomes are fully attached to the spindle, they align at the midplate between poles. This marks the middle of mitosis, which is ____ . As sister chromatids separate, cells enter ____ and they finish separating and a nucleus reforms around each set of new chromosomes in ____ . During this phase, cytokinesis also becomes visible as the cells themselves begin to divide.
Answer:

Mitosis is the division of the cell and begins with a stage called prophase. As the nuclear envelope finishes dissolving, the cells enter prometaphase, where microtubules from the spindle attach to the duplicated X-shaped chromosomes.
When all chromosomes are fully attached to the spindle, they align at the midplate between poles. This marks the middle of mitosis, which is metaphase. As sister chromatids separate, cells enter anaphase and they finish separating, and a nucleus reforms around each set of new chromosomes in telophase. During this phase, cytokinesis also becomes visible as the cells themselves begin to divide.

Answer :the answer is D
Explanation:
Identify the true statements regarding liver glycogen phosphorylase a. Protein phosphatase 1 is abbreviated PP1. The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form to the inactive form. Liver phosphorylase a concentration decreases when glucose enters the blood. As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. Liver phosphorylase a is regulated by AMP, adenosine monophosphate. When PP1 is bound to phosphorylase a, both PP1 and phosphorylase a are active.
Answer:
Liver phosphorylase a concentration decreases when glucose enters the blood.
The binding of glucose to liver phosphorylase a shifts the equilibrium from the active form
As the concentration of phosphorylase a decreases, the activity of glycogen synthase increases. to the inactive form
Explanation:
Protein phosphatase 1 (PP1) is a phosphatase enzyme known to remove phosphate groups from serine/threonine amino acid residues. PP1 plays diverse biological roles including, among others, cell progression, control of glucose metabolism, muscle contraction, etc. In glucose metabolism, PP1 regulates diverse glycogen metabolizing enzymes (e.g., glycogen synthase, glycogen phosphorylase, etc). In the liver, glycogen phosphorylase catalyzes the rate-limiting step in glycogenolysis by releasing glucose-1-phosphate. Glycogen phosphorylase a is converted (and inactivated) into the b form by PP1, which catalyzes the hydrolysis of the phosphate bond between serine and the phosphoryl group. In the liver, glucose binds in order to inhibit glycogen phosphorylase a, thereby inducing the dissociation and activation of PP1 from glycogen phosphorylase a.

In bacterial communities, where resources are often limited, survival requires the ability to sense, respond to, and cooperate or compete with neighboring organisms.
a. True
b. False
Answer:
Explanation:
True.
In bacterial communities, where resources are often limited, survival requires the ability to sense, respond to, and cooperate or compete with neighboring organisms is a true statement.
What are Bacterial communities?Bacterial communities differ in their species makeup, the niches they occupy, and the effects they have on various ecosystems.
Communities defy a single, fundamental definition due to their complexity. Instead, they offer fascinating illustrations of dynamic processes that vary with ecological size. In the beginning of microbiology, there were difficulties in describing and classifying communities.
Robert Koch revolutionized the study of microbiology in the late 1800s by inventing his techniques for proving the link between an infection and an organism (Koch, 1876). Koch's hypotheses continue to be the "gold standard" for linking germs to illness or any other interesting event.
Therefore, In bacterial communities, where resources are often limited, survival requires the ability to sense, respond to, and cooperate or compete with neighboring organisms is a true statement.
