Integrins connect the extracellular environment and allow the cell to move by interacting with which intracellular components? A. desmoglein and dynein B. actin and myosin C. fibronectin and laminins D. selectins and centrosomes
Transmembrane proteoglycans serve as co-receptors for matrix components; nonetheless, integrins are the primary receptors on animal cells that bind the majority of extracellular matrix proteins, including as collagen, fibronectin, and laminin.
These belong to a broad family of homologous transmembrane, cell-matrix adhesion receptors. Integrins, like other cell adhesion molecules, differ from hormone receptors and other extracellular soluble signal molecules in that they typically bind their ligands with lower affinity and are typically present at a concentration on the cell surface that is between tenfold and one hundredfold higher. If the binding was too strong, cells would likely become stuck to the matrix and unable to move, which is not a problem if attachment depends on a lot of weak adhesions. An illustration of the "Velcro principle" is this. Integrins, like other transmembrane cell adhesion proteins, do more than only connect a cell to its environment. Additionally, they stimulate internal signaling pathways that inform cells about the characteristics of the extracellular matrix by bound.

show a dihybrid cross for fruit flies. wwrr x wwrr. be careful when counting the number for each phenotype, it is easy to make a mistake. write the phenotype ratios below.
A dihybrid cross is a cross between individuals that are heterozygous for two different traits. In this example, a dihybrid cross for fruit flies with the genotype wwrr (wild-type red-eyed) x wwrr (wild-type red-eyed) would look like this:
WWrr x WWrr
| |
WwRr WwRr
| |
WwrR WwrR
| |
Wwrr Wwrr
The phenotype ratio for this dihybrid cross would be 9 wild-type red-eyed : 3 wild-type white-eyed : 3 red-eyed mutant : 1 white-eyed mutant.This ratio can be determined by using the Punnett square, which is a tool used to predict the outcomes of genetic crosses by showing all possible combinations of alleles from each parent. In this case, the Punnett square shows that there are four possible combinations of alleles for each trait: Ww for the wild-type allele and w for the mutant allele for eye color, and Rr for the red allele and rr for the white allele for eye color. Each combination of alleles has a 25% chance of occurring, resulting in the above phenotype ratio.In summary, the dihybrid cross between fruit flies with the genotype wwrr (wild-type red-eyed) x wwrr (wild-type red-eyed) results in the phenotype ratio of 9 wild-type red-eyed : 3 wild-type white-eyed : 3 red-eyed mutant : 1 white-eyed mutant.

Master regulatory genes play critical roles in development. Predict the MOST likely fate of a fly embryo where master regulatory genes were nonfunctional due to mutation
a) Cell division would stop, and the embryo would halt development.
b) The embryo would be a collection of undifferentiated cells because they never get the message that will send them down a determination pathway.
c) The embryo would be a combination of differentiated and undifferentiated cells because, even in the absence of a functional master regulatory gene, some cells will differentiate on their own.
d) The embryo would continue to develop, but there is a high probability that some limbs may end up in the wrong place in the adult.
The embryo would be a collection of undifferentiated cells because they never get the message that will send them down a determination pathway. Hence, b is the correct option.
Why undifferentiated cells never get the message?Embryonic genes are a set of genes that are active during the formation and development of an embryo. These genes control a wide range of processes, including cell division, differentiation, and the formation of specific structures and organs. Some of these genes, known as master regulatory genes, play a particularly important role in controlling the overall pattern of development.
Regulator genes, as the name implies, aid in the regulation of the expression of other genes; however, not all genes are expressed in all cells or under all conditions.

If maize seeds are sown at a spacing of 60 cm
by 90 cm, what is the plant population of maize
expected on one hectare of farmland?
The plant population of maize expected on one hectare of farmland is 1.85 x 10000 = 18,500.
To calculate the plant population of maize expected on one hectare of farmland, we need to determine the number of plants that can be planted per square meter and then multiply that by the number of square meters in a hectare.
A 60 cm by 90 cm spacing is equivalent to 0.6 m by 0.9 m or 0.54 square meters per plant. So, one square meter can accommodate 1/0.54 = 1.85 plants.
A hectare equals 10,000 square meters (1 ha = 10000 m^2). So, if we multiply the number of plants per square meter (1.85 plants/m^2) by the number of square meters in a hectare (10,000 m^2), we get the number of plants expected on one hectare of farmland.
