True [87]

Answer:

Using those measurements, the equatorial circumference of Earth is about 24,901 miles (40,075 km). However, from pole-to-pole — the meridional circumference — Earth is only 24,860 miles (40,008 km) around. This shape, caused by the flattening at the poles, is called an oblate spheroid

Alleles of the gene that determines seed coat patterns in lentils can be organized in dominance series: marbled > spotted = d
SSSSS [86.1K]

Answer:

a.The phenotypic proportions obtained after having the genotypes are 50% marbled seeds, 25% spotted and dotted seeds since they are codominant, 25% spotted seeds.

b. Taking into account the F1 genotypes in the previous point, the expected phenotypes for the first crossing are 100% marbled seeds and for the second crossing 100% dotted seeds.

Explanation:

Let's suppose:

Marbled allele: M

Spotted allele: S

Dotted allele: D

Allele for Clear: C

a. Because both crosses were between homozygous parents, the entire F1 genotype is the same.

For the first crossing the descendants have the MS genotype, and for the second crossing the descendants have the DC genotype. It is enough to make a Punnett square to obtain the different combinations of genotypes between the crossing of MS and DC.

the northern leopard frog, tree frog, and wood frog are all different species of frogs. why is having a scientific name for each
guapka [62]

These names are significant because they enable clear communication about animal species among people all across the world.

<h3 /><h3>What are the significance of northern leopard frogs?</h3>

In ponds where it lives, the northern leopard frog is probably a significant indicator of the water's quality. This species is an essential component of the food chain, and tadpoles, which are the main eaters of algae in ponds, can have a big impact.

<h3>What distinguishes tree frogs from other frog species?</h3>

These frogs are most easily recognized by their feet, which have claw-shaped toe bones as their last bone. They can also climb trees thanks to toe pads with small suction cups and extraskeletal structures on their toes. They are available in a number of hues, the most popular being green, gray, or brown.

In the energy pyramid below, what would most likely happen to all other levels if a disease killed off all of the rabbits? *
Pavlova-9 [17]
The answer is A. Rabbits eat grass. The snakes eat the rabbits and the hawks eat the snakes. So if rabbits died off, so would the snakes, and the hawks. Because both of their food sources would deplete. And grass would flourish.
