Which statement is most true about a hypothesis?

In polar areas, solar radiation strikes Earth at a _____.

Option B, small angle, is the right answer.

The polar areas are also known as the freezing zones are the areas of Earth, are the regions of the planet that encompass its terrestrial poles (the South and North Poles), extending in the polar rings. The term solar radiation is referred to as the electromagnetic radiation released by the sun. In the Polar Zone, the radiations from the Sun hit the surface at a small angle. As a result of this, the distribution of light increases in the atmosphere of the earth.

Determine the phenotypic ratios of the offspring. 9 yellow-inflated : 3 yellow-constricted : 3 green-inflated: 1 green-constrict

skad [1K]

From a cross between dihybrid individuals, whose diallelic genes code for one trait each, expressing complete dominance, the phenotypic ratio is B) 9 green-inflated : 3 green-constricted : 3 yellow-inflated :1 yellow-constricted.

-------------------------------

Since I do not have the cross, I will assume the cross involves two dihybrid individuals by looking at the options.

So, let us picture the situation,

Two diallelic genes code for one trait each, color and inflated/constricted pods.
G allele is the dominant and codes for green pods
g allele is recessive and codes for yellow pods
I is the dominant allele and codes for inflated pods
i is recessive and codes for constricted pods
These genes are not linked

1st Cross) Two h0m0zyg0us individuals

Parental) GGII x ggii

F1) 100% GgIi

2nd Cross) Selfcross between F1 individuals

Parentals) GgIi x GgIi

Gametes) GI, Gi, gI, gi

GI, Gi, gI, gi

Punnett square) GI Gi gI gi

GI GGII GGIi GgII GgIi

Gi GGIi GGii GgIi Ggii

gI GgII GgIi ggII ggIi

gi GgIi Ggii ggIi ggii

F2) Genotype

1/16 GGII
2/16 GGIi
1/16 GGii
2/16 GgII
4/16 GgIi
2/16 Ggii
1/16 ggII
2/16 ggIi
1/16 ggii

Phenotype

9/16 G-I- ⇒ Green and Inflated
3/16 G-ii ⇒ Green and constricted
3/16 ggI- ⇒ Yellow and inflated
1/16 ggii ⇒ Yellow and constricted

Phenotypic ratio 9:3:3:1

Options

A) 9 yellow-inflated : 3 yellow-constricted : 3 green-inflated: 1 green-constricted ⇒ NOT CORRECT

B) 9 green-inflated : 3 green-constricted : 3 yellow-inflated : 1 yellow-constricted ⇒ CORRECT

C) 9 green-constricted : 3 green-inflated : 3 yellow-constricted : 1 yellow-inflated ⇒ NOT CORRECT

D) 9 yellow-constricted : 3 yellow-inflated : 3 green-constricted : 1 green-inflated ⇒ NOT CORRECT

How does a plant obtain its food?

PolarNik [594]

Plants are called producers because they make – or produce – their own food. ... They convert these ingredients into food by using energy from sunlight. This process is called photosynthesis, which means 'making out of light'. The foods are called glucose and starch.

Hope it helps!!!
