If temperatures are too high, the leaves from these delicate plants will whilt and die. If there is too much rain, the leaves will fall off and the plant will lose it natural beauty. High temperatures affect animals because the can become too dehydrated and can lack energy and strength, this can be negative if they are being hunted. Too much rain affects animals because they can struggle to find shelter in the rain and can get caught up in an overflow of muddy water.

Dmitry [639]

Answer and Explanation:

There are three phenotypes, so it seems that this an example of incomplete dominance, with the short tail being the intermediate form between long-tail and no-tail. Incomplete dominance is a condition where neither of the alleles completely dominates over the other one. Dominant alleles cannot completely cover up the recessive alleles. Descendents possess an intermediate phenotype between the two parental phenotypes and not the dominant one, which would appear if this would be the case of complete dominance.

Available data:

Two short-tailed Manx cats are bred together.

F1: 3 kittens with long tails, 5 short tails, and 2 without tails.

The T gene might express the tail trait. T allele expresses long the tail and is dominant over t allele which expresses the absence of the tail.

So, homozygous dominant individuals, TT, are long-tailed animals

homozygous recessive individuals, tt, have no tail

Heterozygous individuals, Tt, are short-tailed animals, the intermediate form.

Cross: Two short-tailed Manx cats are bred together

Parental) Tt x Tt

Gametes) T t T t

Punnet Square) T t

T TT Tt

t Tt tt

F1) 1/4 TT = Long-tailed animals

2/4=1/2 Tt = Short-tailed animals

1/4 tt = untailed animals

The ratio 3:5:2 of the progeny in the example is close enough to the Mendelian ratio 1:2:1.

Elodia [21]

The answer is tropical savanna. The region’s ecosystem is characterized by tall grasses, shrubs, and a scattered distribution of trees (especially acacia trees). Large regions of tropical savanna extend through the nations of Botswana, Namibia, and Kenya in Africa. Savannas are also characterized by seasonal water availability, with the majority of rainfall confined to one season. They are frequently found in transitional zones between forest and desert or grassland.

PLS HELP!!! I'LL GIVE BRAINLY!!!

USPshnik [31]

Answer:

See the answer below

Explanation:

First, let us look at the complete equation of respiration:

$C_6H_1_2O_6 + 6O_2 -->6CO_2 + 6H_2O$

The respective number of each atom in the reactants and the products can be filled in the table thus:

Types of atom Number of atom in reactants Number of atom in products

Carbon 6 6

Hydrogen 12 12

Oxygen 18 18

The total number of each atom in the reactants is equal to the total number in the products. Hence, the calculation confirms the law of conservation of matter that says that matters can neither be created nor destroyed, but can be converted from one form to another in a course of a reaction.
