Answer: C. is your answer
I hope you meant, a cross between BbPp and BbPp, else for bbpp x bbpp, all the progeny will be bbpp.
We need to work out a Punnett square to determine the genotypes resulting from the cross between BbPp and BbPp. The dyhybrid cross results in 16 different genotypes, of which a few have the same phenotypes.
It can be seen that there are 4 different kinds of phenotypes present, in the ratio 9:3:3:1.
Answer:
Hip joint
Explanation:
Coxofemoral joint or hip joint. This joint joins the femoral head with the cotyloid cavity of the iliac or coxal bone. Together with the sacrum and the coccyx, both iliacs form a bony waist called the pelvis.
Joint capsule: It is a fibrous cuff that is inserted into the bone perimeter of the cotyloid cavity and the neck of the femur. The capsule is upholstered by a synovial.
Iliofemoral or Bertín: It is inserted in the anterior inferior iliac spine. It is directed downwards through two upper or iliopretrochanteric F.s: it is inserted in front of the facsimiles: F. lower trochanter major or iliopretrochanteric: it is inserted in front of the smaller trochanter.
Pubofemoral: It is inserted into iliopectine eminence, it ends in retrocantineal depression.
Ischio-femoral: It is located on the back of the joint. It originates in the subcotiloid canal and in the periarticular impeller. It ends on the inner side of the greater trochanter (in front of the digital pit).
- Round ligament
- Capsuar ligament.
Round ligament: Measures 3 cm long. It is intraarticular. It extends from the femoral head to the ischiopubial recess of the iliac. It has three fascicles Anterior ends at the anterior end of the recess. Medium ends in the transverse ligament of the Posterior acetabulum passes under the transverse ligament and joins the bone outside the notch.
The round ligament has an artery inside it that supplies the head of the femur. This artery is the branch of the obturator artery. The bottom of the acetabulum, head of the thorn femurllion of the ischium, iliac spine is removed.
Answer:
Oswald Avery, Colin MacLeod, and Maclyn McCarty showed that DNA (not proteins) can transform the properties of cells, clarifying the chemical nature of genes. Avery, MacLeod and McCarty identified DNA as the "transforming principle" while studying Streptococcus pneumoniae, bacteria that can cause pneumonia.

Hi!
The answers would be 1. (D) and 2. (B)
<h3>Explanation of Answer 1</h3>
Ice cores are in essence drilled cylinders that are acquired from glaciers or ice sheets. Ice sheets and glaciers are formed over many years as a result of deposits of snow layers. As these layers form, the lower layers become denser with each new layer, owing to pressure, and in the process it traps the air, which is preserved in the form of bubbles in the layer, therein preserving the composition of the air at a particular period of time. Scientists use ice cores to compare the atmospheric composition of previous years to those of recent years, and the gas mainly studied is carbon dioxide owing to its bringing about a climatic change.
<h3>Explanation of Answer 2</h3>
The Earth's orbit is caused by the gravitational attraction that is present between the Earth and the Sun, but changes due to the shape of the orbit (eccentricity), the wobble of the Earth about its axis (precession), and the axial tilt of the Earth (obliquity). These cause a change in the Earths orbit, which give rise to Milankovitch's cycles. Milankovitch's Cycles describes a revolutionary movement of the Earth around the Sun. These cycles are observed to be determinants of the climate of the Earth, in the regard of how much heat or energy the Earth is exposed to.
Hope this helps!
