Answer: The combination produced is RRtt.
The combination rrTt does not appear in this punnett square.
Explanation:
As the problem does not indicate more information, I assume that punnett square is made between two RRtt genotypes. It can produce gametes that have the alleles Rt. A gamete is a sexual cell (egg or sperm) that has only one allele of each gene. And, each gamete codes for a different gene. Since here we have two different types of alleles (R and t), it is a dihybrid cross.
<u>A Punnett square is a diagram used to predict the genotypes of a cross or breeding experiment.</u> It is used to determine the genotypes and phenotypes of the offspring. To do it, you have to label the rows with one parent's gametes and label the columns with the other parent's genotype. Then, have each box inherit letters from its row and column, and interpret the results.
Then, the punnett square (shown in the picture) will be between RRtt and RRtt whose gametes can only be Rt, so Rt x Rt will be made.
The result in an offspring which will be 100% RRtt, and there is no rrTt combination here because non of the parents have an r allele, then none of the children can inherit it.
To have an offspring where rrTt genotype is shown, a different genotype must be used, in which both parents must have at least one r allele and one t allele. For example, it could be Rrtt x rrTt.
Hypothalamus
When there is abnormally high internal temperature, sensors
in the Central Nervous System send signals to the hypothalamus. The hypothalamus initiates thermoregulation
by sending messages to various organs and body systems with a various
mechanisms. High temperature will set off sweating and vasodilation to cool down
the body.
• Genes can contain more than one polyadenylation site, which alters the 3' of the mRNA transcript and the inclusion/exclusion of exons.
• mRNA transcripts from the same gene can be differentially spliced to include/exclude exons.
Explanation:
Photosynthesis is a chemical pathway that’s integral to producing energy in plants and other primary producers. Energy stored within carbohydrates, like molecules of glucose is produced from light, water and carbon dioxide while oxygen is released.
6CO2 + 6H20 + (energy) → C6H12O6 + 6O2 Carbon dioxide + water + energy
Carbohydrates molecules that supply energy and provide support; they consist of mainly sugars or starches in long chains and rings to form monosaccharide monomers. Inclusive of monosaccharides, disaccharides and polysaccharides (which describes the type of bonding and the degree of complexity of the polymers), their basic makeup comprises C, H, O -with many polar OH groups.
The energy they store, is required by all living organisms for biological processes; these undergo respiration, in order to release energy stored within its bonds, in the form of the molecule ATP.
