Answer:
the last one is:
In the process of meiosis, alleles separate and are added to the gametes in an independent manner. While each gamete (egg or sperm cell) therefore contains one allele for each gene, it's impossible to know which allele, because alleles segregate in a random manner. However, it's possible to calculate probabilities that the offspring will have a given allele using Punnett squares.
Explanation:
Crossing over process results in new combinations of alleles in the gametes (egg or sperm) formed, which ensures genomic variation in any offspring produced.
What do you mean by crossing over process?Chromosomal crossover, or crossing over, is the exchange of genetic material during sexual reproduction between two homologous chromosomes' non-sister chromatids that results in recombinant chromosomes.
This process, also known as crossing over, creates gametes that contain new combinations of genes, which helps maximize the genetic diversity of any offspring that result from the eventual union of two gametes during sexual reproduction.
Crossing over is an enzyme-mediated process, where the exchange of genetic material between non-sister chromatids of homologous chromosomes takes place.

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.

Answer:
I believe the answer is D
Explanation:
how does proteinsynthesis happen in the ribosome
First of all, transcription needs to happen inside the nucleus. An enzyme called RNA polymerase uses a strand of DNA as template for mRNA (messenger RNA) synthesis. The mRNA contains the codons. The next step of protein syntheis is called translation and occurs in the ribosome. Codons are groups of three letters that code for an amino acid. When the mRNA comes to the ribosome each codon pairs with an anticodon. Groups of three base pairs that are complementary to codons and are present in the tRNA(transfer RNA).
Each tRNA molecule has an amino acid attached to it and a specific anticodon. Depending on the order of codons proteins are build by binding amino acids.

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.

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.
