Double circulation is when for every circuit, blood circulates twice through the human heart.

Firstly, deoxygenated blood is sent by the right pump m to the lungs. After it then becomes oxygenated, it will then be taken back to the heart and them the oxygenated blood will then be carried round bmthe body by the left pump.

Answer:

Cellular respiration uses energy in glucose to make ATP. Aerobic (“oxygen-using”) respiration occurs in three stages: glycolysis, the Krebs cycle, and electron transport. In glycolysis, glucose is split into two molecules of pyruvate. ... Life first evolved in the absence of oxygen, and glycolysis does not require oxygen.

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.

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.

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.

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)

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.

The cell will have to use its energy to move materials through its membrane in case of active transport.

The fundamental structural and operational unit of all living things is the cell. Each cell has a cytoplasm that is surrounded by a membrane and is home to a variety of biomolecules, including nucleic acids and proteins.

Cells can develop specialized functions and perform a variety of tasks within the cell, including protein synthesis, DNA repair, replication, and motility. Within the cell, cells can specialize and move around. Because of their small size, the majority of cells are quantified in micrometers.

Cranium is the outer layer that protects the skull. It consists of three parts: the frontal bone, occipital bone, and two parietal bones.

The frontal bone is a single bone that transforms into a forehead and it is positioned atop the eyes' orbit.

The frontal bone also forms both sides of the upper jawbone or maxilla. While the two parietal bones form the top and side of the human skull.

They also take part in forming the largest part of the upper jawbone like the frontal bone.
