Option A: Postcranial changes in hominins that indicate bipedal locomotion include shortening and broadening of the ilium of the pelvic girdle.
Around 3 million years ago, bipedal locomotion in early hominins turned to be more effective. This adaption made the hominins more stable to hold their weight and walk upright. It also helped them to see longer distances in the green forests areas. They could take the advantage of hunting their food or protecting them from harmful predators. Adapting bipedal location expended lesser energy, thus allowing hominins to walk longer distances.
Over many generations now, bipedal location turned out to develop stronger and longer legs and feet so as to allow running and holding more weights. Additionally, the arms turned to be more adapted to hold the heavier things efficiently and to carry their newborns effectively.
Owing all these changes, adaption made to this kind of locomotion include shortening and broadening of the ilium of the pelvic girdle and developed a bowl-shape structure.
Thus, option A is the correct answer.

Glycolysis results in the net production of which of the following sets of molecules per glucose molecule?
Answer:
Glycolosis has a net gain of 2 atp
Explanation:
It produces 4 but you invest 2 to start so its only net gain of 2
You also ge 2 pyruvate and 2 NADH
Two pyruvate molecules, two ATP molecules, and two NADH molecules are the substances produced in the process of glycolysis.
These substances are gained from glucose in order to generate energy which is needed in different activities of the cell. ATP is the molecule which is used by the cell for doing activities which needs energy.
Both pyruvate and NADH molecules are also converted into ATP molecules in the end and used by the cell so we can conclude that in the process of glycolysis, two pyruvate, two ATP, and two NADH molecules are formed.

a population of deer was threatened with overpopulation until cheetahs were imported. after a couple of years, there were fewer deer, but the average running speed of the deer had increased. this is an example of Predator-prey coevolution.
Overpopulation is a condition when a species have so much population that the carrying capacities of the nature starts getting exhausted.
Overpopulation is also not good for a population because it will causes depletion of the resources which will ultimately lead to the extinction of the species.
When the cheetahs are introduced in an area overpopulated with deer species, they will keep the population in check. Also, as deer have to save itself they have to increase their running speed to survive and hence evolve with same adaptation.

Warm, more dense molten material rises while cool, less dense material sinks creating convection currents which cause the tectonic plates to move. The correct option is A.
What is tectonic plate movement?Tectonic movements are the subsurface movement of formations caused by natural Earth forces.
Plate movement results in three types of tectonic boundaries: convergent boundaries, where plates move into one another, divergent boundaries, where plates move apart, and transform boundaries, where plates move sideways in relation to one another.
As thermal energy from the core heats the mantle, molten material rises toward the crust and begins to cool.
As the material cools, it sinks back toward the core, dragging some of the crust with it. Convection currents in the Earth's mantle move the plates and shape the continents.
Thus, the correct option is A.

humans have hundreds of different g-protein-coupled receptors. while these receptors all have distinct amino acid sequences, they all have in common: guanine nucleotide exchange activity
What is guanine nucleotide?
Guanine nucleotide exchange factors (GEFs) are proteins or protein domains that stimulate the release of guanosine diphosphate (GDP) to enable the binding of guanosine triphosphate, hence activating monomeric GTPases (GTP). It has been demonstrated that guanine nucleotide exchange activity occurs in a number of unrelated structural domains. While some GEFs are exclusive to a particular GTPase, others can activate numerous GTPases.
Small GTPases are activated by proteins or protein domains known as guanine nucleotide exchange factors (GEFs). In intracellular signaling pathways, small GTPases function as molecular switches and have a wide range of downstream destinations. The Ras superfamily of GTPases, which is made up of the most well-known GTPases, is crucial for key cellular functions such cell division and proliferation, cytoskeletal structure, vesicle trafficking, and nuclear transport. GTPases can have their activity controlled by GEFs and the opposing GTPase activating proteins because they are active when bound to GTP and inactive when attached to GDP (GAPs)

What are the possible blood types of a baby with a mom who is heterozygous for blood type A and a dad with type O?
Answer:
A & O group
Explanation:
Dad will be having io io allele and mom will be having ia io
The possible blood types for the baby are either A or O, with equal likelihood of 50% for each.
What is blood type?A classification system called blood type explains whether or not specific antigens are present on the surface of red blood cells. Each of the four major blood types—A, B, AB, and O—has distinct antigen markers.
A and O are the two possible blood types for a child whose mother is heterozygous for blood type A (genotype AO) and whose father has type O (genotype OO).
A baby has a 50% chance of acquiring the A allele from the mother and a 50% chance of inheriting the O allele from the father because each parent gives one of their two blood type genes to their offspring.
Baby with blood type A inherits the A allele from the mother and the O allele from the father (genotype AO).
The child will have blood type O if both parents carry the O allele (genotype OO).
Therefore, the possible blood types for the baby are either A or O, with equal likelihood of 50% for each.
