In this instance, a dominant allele was responsible for her brown eyes.
Dominant alleles: what are they?A dominant allele is a gene variant that, even in the presence of other alleles, will cause a certain phenotype.Usually, a dominant allele codes for a protein that functions. One copy of the allele generates enough enzyme for a cell to have an abundance of a certain product, which is why the allele is dominant.What makes a gene a dominant allele?Because it hides the recessive trait and manifests in the phenotype of a heterozygous creature, a dominant allele is referred to as dominant.

which provides long term energy storage
Answer: Glycogen
Explanation:
It provides long-term energy storage.
Further Explanation
Living organisms require energy in order to undertake their daily activities such as growth and development, locomotion, gaseous exchange, etc. To do so they obtain nutrients for short-term and long-term energy source.
Carbohydrates are the major energy source for living organisms, however, living organisms may use other sources of energy such as proteins or fats when carbohydrates is out of stock or not available.
Energy source in animals
Animals use simple carbohydrates such as glucose obtained from diet for short-term energy sources.
These simple carbohydrates may also be stored for future use in the form of glycogen, which makes glycogen a long-term energy source, to be used when need arises.
When glucose levels are low in the body hormones in the body trigger the breakdown of glycogen to glucose.
Other sources of energy such as proteins and fats are used when carbohydrates storage is depleted, for example during starvation.
Energy source in plants
In plants, on the other hand, simple carbohydrates are similarly used as a short term source of energy. Additionally, simple molecules such as glucose are stored in the form of starch for long-term source of energy for the plants.

Both in people and animals, acute myeloid leukemia reduces the number of osteoblasts.
A pharmaceutical approach to osteoblast restoration in leukemic mice decreases tumor burden across the board and lengthens survival.
According to theory, the bone marrow niche serves as a permissive microenvironment necessary for the genesis or development of hematopoietic malignancies. We proposed that leukemic blasts are influenced by osteoblasts, niche elements vital to hematopoietic stem cell (HSC) activity.In mice models of acute leukemia, genetic osteoblast depletion increased the number of circulating blasts and tumor engraftment in the marrow and spleen, which raised tumor burden and decreased survival. Hematopoietic lineage/progression may have been altered since myelopoiesis rose, was accompanied by a decline in B lymphopoiesis, and was impaired by erythropoiesis.Osteoblast loss was prevented in mice with acute myeloid or lymphoblastic leukemia treated with a pharmaceutical inhibitor of the manufacture of duodenal serotonin, a hormone that reduces the number of osteoblasts.Therefore, osteoblasts and leukemia are related.

Flaviviruses are a bunch of enveloped positive-stranded RNA viruses accountable for notable mortality and morbidity throughout the world. Flaviviruses fuse with the endosomal membranes of the prey cell in a pH-dependent fashion by entering cells via a clathrin-dependent endocytic pathway. Flaviviruses derived from the endoplasmic reticulum assemble at bud into membranes as immature virions on which E and prM proteins interact as heterotrimeric spikes.
The flaviviruses maturation process is staged by the proteolytic cleavage of the precursor membrane protein into shifting to infectious particles from the inert virus. The peptide β-barrel structure consists of the fusion loop in E, controlling fusion with host cell membranes. during maturation, The structure helps to identify the stages of the pH-directed conformational metamorphosis and leads to the release of pr when budding from the host.

msd2, an apoplastic mn-sod, contributes to root skotomorphogenic growth by modulating ros distribution in arabidopsis
The correct answer is because MSD2 an apoplastic regulates ROS distribution during root skotomorphogenesis it plays an important role in plant growth and development.
MSD2 expression in roots is light condition dependent, implying that MSD2 may influence ROS metabolism in roots during the light-to-dark transition. ROS distribution, which exhibits an opposite gradient of H2O2 and O2radical dot in etiolated msd2 mutants and is accompanied by changes in the onset of differentiation, governs root architecture. MSD2 is secreted and has SOD activity that can be inhibited by tyrosine 68 nitration. Although membrane-localized NADPH oxidases are well known for producing ROS during developmental and stress responses, the metabolic pathways of the superoxide (O2radical dot) produced by them in the apoplast are poorly understood, and the identity of the apoplastic superoxide dismutase (SOD) in Arabidopsis is unknown.
