The ischium bone forms the superior part of the pelvic girdle.
<h3>What is the structure of the pelvic girdle?</h3>
In the bottom region of the trunk, there is a bony structure known as the pelvic girdle that resembles a ring. It joins the lower limbs to the axial skeleton. There are two types of pelvises: the bigger pelvic and the lesser pelvis.
The pelvis is made up of two paired hipbones that are joined at the pubic symphysis in front and by the sacrum in back. Each hipbone is composed of three bones: the blade-shaped ilium above and to either side, which determines the hips' width; the ischium below, on which the weight is placed when sitting; and the pubis in front. Early in maturity, all three come together at a triangle suture in the acetabulum, the cup-shaped socket that connects to the head of the femur to create the hip joint.

The attached picture shows how bacteria gain antibiotic resistance. Firstly, a few individuals attain a
beneficial mutation in their genetic material that accords them the capability to survive in an antibiotic. The
individuals are hence able to survive and
reproduce more than those individuals without the mutation. There is, therefore, a genetic
shift in the population in favor of the resistant genotype. After generations, the
whole population becomes antibiotic resistant.
Answer:
Explanation: Carnivore because it eats meat (other animals)
Genetically modified organisms are those organisms in which certain gene is inserted to get the desired beneficial results.
Explanation:
A genetically modified organism is an organism or plant altered for beneficial traits which would not have been possible by the traditional mating process or recombination techniques.
Genetic engineering is the technique involved for the construction of gene of interest and inserting them in the host species for getting expressed.
Many fruitful results have come out like a tomato of long shelf life k/a flavr savr.
Apart from molecular techniques used for cloning, CRISPR is the recent innovation which had made it very simple.
The GMOs can solve the food problem of the world as Single-cell proteins and longer shelved life food.
Disease resistant plants can be formed for better yields.
Nutrition level of food can be increased.
Example of GMO are canola, corn, papaya, soy and many animals are also on the list.
Answer: More than 99 percent of all organisms that have ever lived on Earth are extinct. As new species evolve to fit ever changing ecological niches, older species fade away. But the rate of extinction is far from constant. At least a handful of times in the last 500 million years, 75 to more than 90 percent of all species on Earth have disappeared in a geological blink of an eye in catastrophes we call mass extinctions.
Though mass extinctions are deadly events, they open up the planet for new forms of life to emerge. The most studied mass extinction, which marked the boundary between the Cretaceous and Paleogene periods about 66 million years ago, killed off the nonavian dinosaurs and made room for mammals and birds to rapidly diversify
