How are thorns and spines related to drought resistance?

Biology
1 answer:
Tresset [83]2 years ago
7 0

Answer:

To survive in drought conditions, plants need to decrease transpiration to limit their water loss. Some plants that live in dry conditions have evolved to have smaller leaves and therefore fewer stomata. Extreme examples are plants with leaves that resemble spiky thorns or spines.

In a particular family, one parent has Type A blood, the other has Type B. They have four children. One has Type A, one has Type
AlladinOne [14]

Answer:

The correct answer is -

Parental genotypes: AO & BO

Children genotypes: AB, AO, BO, and OO

Explanation:

In the human blood group system, more than two types of alleles are present that lead to the existence of four blood groups in the human population.

Here, A and B alleles are co-dominant while the O allele is recessive to both A and B alleles in the ABO system.

The cross depicting the genotypes of children is

IA IO

IB    IAIB    IBIO

IO   IAIO   IOIO

In this cross, we get the same result as given in the question -

One parent has A and the other has B type blood while the children have all four types of blood groups One has Type A, one has Type B, one has Type AB, and the last has Type O. It is possible only when parents are heterozygous in their genotypes and not expressing codominance.

Giant pandas use their thumbs to grip and eat bamboo. They spend most of their time eating and save energy by not moving much. T
emmasim [6.3K]

Answer:

Explanation:

For many years, scientists wondered whether pandas were a type of bear, raccoon or something all their own. But plenty of genetic studies have made it clear that pandas are a type of bear, according to the San Diego Zoo.

Also called great pandas, parti-colored bears, bamboo bears and white bears, giant pandas are distinguished from other pandas by their large size and black-and-white coloring. Their bold coloring provides camouflage — giant pandas are nearly invisible in dense patches of bamboo, according to the Smithsonian National Zoo.

Giant pandas grow to be 27 to 32 inches (70 - 80 centimeters) tall at the shoulder, 4 to 5 feet (1.2 to 1.5 meters) long and can weigh up to 275 lbs. (125 kilograms), according to the San Diego Zoo Their size is about the same as an American black bear. By comparison, the giant panda's distant relative, the red panda, is only 20 to 26 inches (50 to 65 cm) tall and weighs 10 to 20 lbs. (4.5 to 9 kg).

In the wild, giant pandas are only found in the remote, mountainous regions of central China, in Sichuan, Shaanxi and Gansu provinces, according to the National Zoo. In this area, between 5,000 and 10,000 feet elevation (1,524 - 3,048 m), are the cool, wet bamboo forests that giant panda's call home. The large bears make their dens from hollowed-out logs or stumps of conifer trees found within the forest.
