Answer:

light

Explanation:

Light is an important growth factor for plants generally because its energy is utilized for food production during photosynthesis.

Complete the sentences to describe natural selection

Vikentia [17]

The environment needs to change in order to natural selection to occur.

Reason:

Because, Natural selection is the differential survival and reproduction of individuals due to differences in phenotype. It is a key mechanism of evolution, the change in the heritable traits characteristic of a population over generations.

2. Population has some genetic variations.

Reason:

Genetic variation is essential for natural selection because natural selection can only increase or decrease frequency of alleles that already exist in the population. Genetic variation is caused by:

mutation and random mating between organisms

3. Nature select organism with specific traits to survive and reproduce.

Reason:

According to Charles Darwin's theory of evolution by natural selection, organisms that possess heritable traits that enable them to better adapt to their environment compared with other members of their species will be more likely to survive, reproduce, and pass more of their genes on to the next generation.

In horses, Chesnut hair color is recessive to black. The pacing gait is recessive to trotting and long hair is recessive to shor

Vitek1552 [10]

9:3: 3:1 is the phenotypic ratio showing traits as black and long hair : black and short hair: chestnut and long hair: chestnut and short hair when a chestnut horse heterozygous for pacing and hair length with a hybrid horse.

Explanation:

Dominant trait = black hair colour (BB,Bb), trotting (TT,Tt) , long hair (LL,Ll)

recessive trait = chesnut hair colour (bb), pacing gait (tt), short hair(ll)

cross between chestnut horse heterozygous for pacing and hair length will have alleles as BbLl

alleles for hybrid horse will also be heterozygous Bb, Ll

Punnett square to show the cross:

BL Bl bL bl

BL BBLL BBLl BbLL BbLl

Bl BBLl BBll BbLl Bbll

bL BbLL BbLl bbLL bbLl

bl BbLl Bbll bblL bbll

phenotype ratio

black and long hair : black and short hair: chestnut and long hair: chestnut and short hair

9:3: 3:1 is the phenotype ratio.
