Answer:
Approximately the number of individuals with each phenotype is:
RS-->0.75 x 1000 = 750rs--> 0.19 x 1000 = 190Rs--> 0.05 x 1000 = 50rS--> 0.05 x 1000 = 50Explanation:
Available data:
Two genes are hypothesized to be linkedThe map distance between the genes is thought to be 12 map units. Two heterozygous parents1000 offspring producedLet us say that the two diallelic genes are R (alleles R and r) and S (alleles S and s)
Heterozygous parents might have the following genotype RS / rs
We know that there are 12mp between genes, which means that the recombination frequency equals 0.12 or 12%.
0.12 of the gametes are recombinants and 0.88 are parentals. There are two types of parentals and two types of recombinant, so 0.06 + 0.06 are recombinants while 0.44 + 0.44 are parentals. This is:
Cross:
Parentals) RS/rs x RS/rs
Gametes) RS (parental) 0.44
rs (parental) 0.44
Rs (Recombinant) 0.06
rS (Recombinant) 0.06
Punnet square) RS rs Rs rS
RS RS/RS RS/rs RS/Rs RS/rS
rs RS/rs rs/rs Rs/rs rS/rs
Rs RS/Rs rs/Rs Rs/Rs rS/Rs
rS RS/rS rs/rS Rs/rS rS/rS
F1) Genotypes:
1 RS/RS --> 0.44x 0.44 = 0.1936 2 RS/rs --> 0.44x 0.44 = 0.1936 x2 = 0.38722 RS/Rs --> 0.44 x 0.06 = 0.264 x 2 = 0.0532 RS/rS --> 0.44 x 0.06 = 0.264 x 2 = 0.0531 rs/rs --> 0.44x 0.44 = 0.1936 2 rs/Rs --> 0.44 x 0.06 = 0.264 x 2 = 0.0532 rS/rs --> 0.44 x 0.06 = 0.264 x 2 = 0.0531 rS/rS --> 0.06 x 0.06 = 0.00361 Rs/Rs --> 0.06 x 0.06 = 0.00362 Rs/rS --> 0.06 x 0.06 = 0.0036 x 2 = 0.0072Phenotypes:
RS-->0.7506 (RS/RS + RS/rs + RS/Rs + RS/rS + Rs/rS)rs--> 0.1936 (rs/rs)Rs--> 0.0566 (rs/Rs + Rs/Rs)rS--> 0.0566 (rS/rS + rS/rs)Now, to know how many individuals would occur in each phenotypic category, you just need to multiply it by 1000, that is the total number of individuals
RS-->0.75 x 1000 = 750rs--> 0.19 x 1000 = 190Rs--> 0.05 x 1000 = 50rS--> 0.05 x 1000 = 50Help me? This is so hard

In silkworms,yellow cocoon (B) is dominat over white cocoon(b). If the mom is BB and the dad is bb, what are the chances they have offspring with yellow cocoons?
Answer:
100 %
Explanation:
Dominance is a genetic phenomenon where a gene variant or allele masks the effects of another allele (of the same gene) in heterozygous individuals. This last gene variant is referred to as the recessive allele. In this case, the silkworm mother can produce only one type of gamete carrying the dominant gene (B) form, while the silkworm father can produce only one type of gamete carrying the recessive gene (b) form. In consequence, from this cross, all offspring (100 %) will be heterozygous (Bb) and therefore they will express the dominant trait (i.e., yellow cocoon).

megakaryocytes are huge cells found in red bone marrow that extend long tendrils into blood sinusoids. The flow of blood breaks off small portions of those tendrils creating the formed element known as
Answer:
Platelet
Explanation:
In 1906 James Homer Wright established that platelets, seen as hyaline bodies or vacuoles, are formed in the cytoplasm of megakaryocytes in the bone marrow, which then disintegrate and pass as platelets into the circulation. Megakaryocytes are cells of the myeloid lineage. They originate platelets (or thrombocytes) by cleaving parts of their enormous cytoplasm directly into a sinusoid vessel. The function of platelets is to form thrombi to prevent blood loss in small blood vessel ruptures.
SARS-CoV-2 is a respiratory virus. What makes a respiratory virus more difficult to contain than a pathogen that is spread through contaminated food, for example?
Answer:
a respiratory virus is usually air borne. while contaminated food can only harm you if ingested. with SARS, if you breath in contaminated air, its a lot easier to get it.

Which stage of human development might be MOST concerned with cognitive function?
middle adulthood
adolescence
early adulthood
advanced adulthood
Answer:
Preschoolers, ages three to six, should be at the "preoperational" stage of Piaget's cognitive development theory, meaning they are using their imagery and memory skills. They should be conditioned to learning and memorizing, and their view of the world is normally very self-centered.
Explanation:
so early adulthood think so
The stage of human development that might be most concerned with cognitive function is advanced adulthood. The correct option is D.
What are cognitive functions?Cognitive functions are the psychological functions that are the mental processes that are done to express feelings and actions. They are eight types of cognitive functions.
In advanced adulthood, humans use most of the cognitive functions of the body.
Thus, the correct option is D, advanced adulthood in regard to the stage of human development.

Cells use a molecule called (DNA / RNA / ATP / CMP) to store and release energy like a battery. The energy is stored in chemical bonds between (nucleotide / oxygen / phosphate / ribose) groups of the molecule, and the energy is released when the chemical bonds are broken.
Answer:
Cells use a molecule called ATP to store and release energy like a battery. The energy is stored in chemical bonds between phosphate groups of the molecule, and the energy is released when the chemical bonds are broken.
Explanation:
The Adenosine Triphosphate (ATP) is a molecule made of adenine, ribose, and three phosphate groups, which are the ones that store the energy in its bounds. The ATP is the molecule that provides the energy to the different processes that happen in a cell. The molecule is made from the glycogen, fats, and carbohydrates that the body has absorbed in the intestines. When the body needs energy, the ATP loses one or two phosphates, becoming ADP and AMP. When the phosphorylation happens, which is the loss of phosphate, the energy is released.

how do plants grow helppp
Answer:
During photosynthesis, plants take the water from the soil, and the carbon dioxide from the air, and they make sugars out of it. When plants have the right balance of water, air, sunlight and nutrients, their cells grow and divide, and the whole plant gets bigger and bigger. And that's how plants grow.

DNA: ATACGAAAT (Type as one word - no spaces)
Using the same strand of DNA, what would be the correct sequence for an RNA strand? (Type as one word - no spaces)
Answer:
TATGCTTTA for question 1.
For RNA following the original strand it would be UAUGCUUUA
Explanation:
Replace A with T(vice versa), and C with G(vice versa)
But for the RNA, A bonds with U instead of T. So it would be the same as the complimentary DNA, just with U instead of T
