Structures that form the voltage sensors of K channels Group of answer choices extend into the intracellular space. are embedded in the cell membrane. are located within the channel pore. extend into the extracellular space. are embedded in the cell membrane but extend into the extracellular space when the membrane is depolarized.
Answer:
are embedded in the cell membrane
Explanation:
Voltage-gated ion channels are transmembrane proteins activated by changes of the electrical potential across the plasma membrane. Structurally, voltage-gated Potassium (K) channels are composed of six transmembrane helices where amino- and carboxyl-terminal peptides are localized intracellularly (in the cytoplasm). The Helices 1 to 4 (H1-H4) comprise the voltage sensor domain that forms an anti-parallel helical bundle. H4 has many positively charged amino acids (Arg and Lys residues) which are key to the voltage-sensing function. Finally, Helices 5 and 6 (H5-H6) form the channel pore which is localized in the center of the protein.

What impact does increased CO2 in the atmosphere have on marine life?
What happens during fertilization that makes the offspring unique compared to the original cells?
Please write the answer in one sentence!
And please, if you do not know the answer, please don´t answer.
Answer:
The union of an egg and sperm forming a zygote is known in biology as fertilization, during this process the zygote becomes a morula, meaning that the female reproductive cell divides after that union generating many other cells together into a solid ball of cells, giving rise to the embryo with the potential for development, fostered by chemical reactions among the sperm enzymes and the egg's plasma; mitosis and meiosis are included throughout the whole process.

explain the two inheritance patterns of blood type
Answer:
The ABO blood type is inherited in an autosomal codominant fashion.
The Rh system of blood groups determines the gene that forms two alleles: dominant (D) and recessive (d).
Explanation:
The dominant allele determines the synthesis of antigen D, so people with this antigen are referred to as Rh +. The recessive allele is dysfunctional so no D antigen is produced and individuals are Rh-
The ABO blood group system determines a gene that has three alleles:
A, B, and O allele.
Alleles A and B are functional and determine the synthesis of certain antigens (agglutinogens A B) that are found on erythrocytes.
In this exercise we have to use the knowledge of blood to explain its inheritance factors, so we want to explain how:
So we know that blood types in addition to the types known as ABO, there is also the RH factor which is the biggest inheritance.
What are the 3 blood types?Type A blood has A antigens, B blood has B antigens, AB blood has both antigens, and type O has neither. Red blood cells also have another type of antigen called RhD, which is part of a family made up of 61 Rh type antigens. When the blood has RhD, it is type positive.
Our blood group is inherited from both parents. Just as we are given physical characteristics like skin color or hair, we also inherit blood type. Surprising as it may seem, blood group is not genetically determined at birth according to the contributions of both parents.

The process takes place in the chloroplasts of green plants and oxygen is a by-product of the reaction.
Cellular respiration, on the other hand, involves the breakdown of foods in the form of glucose to release the energy stored in them for the use of cells. The glucose reacts with oxygen to produce energy in the form of ATP while carbon dioxide and water are produced as by-products. The process takes place in the mitochondrion and both producers and consumers require it in order to generate energy for metabolic processes.

Approximately how many genes are found on
chromosome 112|
Answer:
Down syndrome, Turner syndrome and Klinefelter syndrome.
Explanation:
Down syndrome, Turner syndrome and Klinefelter syndrome are the genetic disorders which are found in chromosome. Down syndrome is a common genetic disorder that occurs when a person has three copies of 21st chromosome. It is also called trisomy 21. Due to this disorder, delays occur in physical and mental developmental and disabilities of human body parts.

3. autism (neurexin 1), acute intermittent porphyria, albinism, ataxia-telangiectasia, Beckwith–Wiedemann syndrome, Best's disease, beta-ketothiolase deficiency, beta thalassemia.
4.Autism is related to some changes in chromosome 11, although it is characterized as a psychological disorder. It is usually identified in childhood, between 1 and a half years and 3 years, although the initial signs sometimes appear in the first months of life. The disorder affects the child's communication and ability to learn and adapt. Chromosome 11 Duplication Syndrome is a chromosomal alteration that interferes with child development, which may trigger motor, cognitive, language and socialization delays, inability to perform simple motor activities, weight and height deficit, facial dimorphisms and congenital malformations. Jacobsen's syndrome is an inherited disorder caused by the deletion of a specific region of the long arm of chromosome 11, which covers the 11q24.1 band. Patients with this disorder have a phenotype characterized by delayed neuropsychomotor development, craniofacial anomalies, diverse heart defects and blood dyscrasias. Signs and symptoms include: Heart defects; mental delay; difficulty feeding in childhood; attention deficit; hyperactivity; skeletal malformation, among others.

Explain why one cell would have so many different kinds of proteins embedded in the cell membrane
Answer:
membrane proteins play different roles (for example, transport of nutrients, signaling pathways, etc)
Explanation:
Membrane proteins are key components that form and interact with biological membranes. Thus, membrane proteins can be classified as 1-integral membrane proteins which are components of the cell membrane and 2-transmembrane proteins that penetrate the membrane in one or both sides of the membrane. These proteins account for different cellular functions. Some functions of membrane proteins include:
- Cell structure (attachment to the extracellular matrix and/or the cytoskeleton)
- Transport of nutrients and waste products
- Intercellular interaction between cells.
- Signaling transduction functions
- Cell recognition (e.g., during innate immune responses)
Answer:
Each type of cell has, in its cell membrane, specific proteins that help it control the intracellular environment and that interact with specific signals from its environment.
Explanation:
Some proteins are completely integrated into the membrane and are called membrane proteins or integral transmembrane proteins since they "cover" both layers of the membrane. Transmembrane proteins are useful to the cell because they can interact with molecules outside the cell and send information about the extracellular environment into the cell. Other proteins are more loosely bound to the inside or outside of the membrane and are called peripheral membrane proteins. Peripheral membrane proteins are often used by the cell during signal transduction - the process by which one cell responds to a signal from another cell.

Why can't all the energy in one trophic level be transferred to the next?
Answer:
Energy decreases as it moves up trophic levels because energy is lost as metabolic heat when the organisms from one trophic level are consumed by organisms from the next level. ... A food chain can usually sustain no more than six energy transfers before all the energy is used up.
