The point where species x and y should be placed is a)at the two points close together toward the upper right of the diagram. So, correct option is a.
A cladogram is a diagram that addresses a speculative connection between gatherings of life forms, including their normal predecessors. The expression "cladogram" comes from the Greek words clados, and that signifies "branch," and gramma, and that signifies "character."
The outline looks like the parts of a tree that broaden outward from a trunk. In any case, the state of the cladogram isn't really vertical. The outline can branch from the side, top, base, or focus. Cladograms can be extremely straightforward, looking at a couple of gatherings of creatures, or exceptionally intricate, possibly characterizing all types of life. In any case, cladograms are more frequently used to characterize creatures than different types of life.
Amar should need to place species x and species y at upper right side of the diagram as on upper right side species will be least primitive for formation.

In reptiles eggs that are kept at warmer temperatures develop into females while eggs that are kept at cooler temperatures develop into males. This pattern of expression can best be explained by
Answer:
TSD ↓
Explanation:
The pattern of sex determination in reptiles that is influenced by the temperature at which the eggs are incubated is known as temperature-dependent sex determination (TSD). This phenomenon is thought to be controlled by hormones and other factors that are sensitive to temperature. For example, if a particular hormone (such as estrogen) is present at higher levels during incubation, it may promote the development of female characteristics in the developing embryo. On the other hand, if this hormone is present at lower levels, it may promote the development of male characteristics. The exact mechanisms underlying TSD are not fully understood, but it is clear that temperature plays a crucial role in determining the sex of these animals.

Cell necrosis is a type of programmed cell death which causes cells to swell and burst, spilling their contents into the extracellular matrix and potentially triggering immune and inflammatory responses.
. It is distinct from necrosis, in which cells pass away as a result of harm.
A multicellular organism's cells are part of a tightly knit community. In this community, the number of cells is strictly regulated, not only by regulating the rate of cell division but also by regulating the rate of cell death. Cells that are no longer required start an intracellular death programme and end their lives. Therefore, although though apoptosis is the more often used term for this process, it is also known as planned cell death.

Paleontology - The Fossil Record Scientists use the age of fossils as evidence for evolution. There are two ways of dating fossils: Relative dating and absolute dating. Relative dating uses a fossil's location in rock layers to determine that fossil's approximate age. Fossils found deeper in the ground are usually the oldest. Using the chart to the right, a paleontologist can therefore know that a fossil found in layer 1 at the dig site is older than a fossil found at layer 6, for example, by relative dating.
Absolute dating determines the fossil's actual age by measuring amount of an element called carbon 4 in the fossil. There is a mathematical formula that will calculate the rate of decay of this element. By measuring the carbon-14 levels and plugging it into the math formula, the scientist can know an actual number of years old a fossil is.

True, The full oxidation of glucose is exergonic and some of the reactions in cellular respiration are endergonic.
In the second phase of glycolysis: phosphorylated sugar molecule is cleaved and the products rearranged.Cells must replenish ATP by synthesising it from ADP and phosphoric acid. This requires energy, and one way of providing this is from the oxidation of glucose which is an exergonic reaction.Under standard conditions, glucose reacts with oxygen during glycolysis to release Gibbs free energy. This is an exergonic reaction, which means energy is released. In order to use up this free energy, this reaction is coupled to other reactions in our body.Cellular respiration is an exergonic reaction; ΔG for this reaction, which converts glucose and oxygen to carbon dioxide and water, is –686 kcal/mol.The events of cellular respiration up to this point are exergonic reactions – they are releasing energy that had been stored in the bonds of the glucose molecule.

Cockroaches are a very old species; its "roachoids" ancestors originally evolved around 320 million years ago, during the Carboniferous epoch. But unlike modern roaches, these ancient roach ancestors lacked internal ovipositors. Cockroaches are among the most primitive extant Neopteran insects due to their generalist nature and lack of specific adaptations (such the sucking mouthparts of aphids and other true bugs). They have teeth for chewing instead. They are widespread, resilient insects that can withstand temperature extremes, including arctic cold and tropical heat. Cockroaches from the tropics are frequently larger than those from the temperate zones.
