What are developmental homologies, and how are they studied?

Biology
1 answer:
7nadin3 [17]3 years ago
5 0

Explanation:

In reference to evolution, homology can be described as the comparative similarities in the structures of organisms that make it more alike to one organism than the other organisms. It also shows the characteristics that might have evolved in an organism over time. Developmental homology are the similarities which arise between organisms due to similar embryological source.

Developmental studies can be made by researching the embryological developments of different organisms and looking for similarities among them.

For example, studying the snake embryos showed that some of the embryos have hind limb buds in them which disappeared in the mature snake. This study made it clear that snakes evolved from organisms that had hind limbs. As the snakes do not need the limbs, so with time the species of snakes evolved and lost their hind limbs.

Why or how are calories "wasted" during gluconeogenesis?
ira [324]

luconeogenesis is a ubiquitous process, present in plants, animals, fungi, bacteria, and other microorganisms.[2] In vertebrates, gluconeogenesis takes place mainly in the liver and, to a lesser extent, in the cortex of the kidneys. In ruminants, this tends to be a continuous process.[3] In many other animals, the process occurs during periods of fasting, starvation, low-carbohydrate diets, or intense exercise. The process is highly endergonic until it is coupled to the hydrolysis of ATP or GTP, effectively making the process exergonic. For example, the pathway leading from pyruvate to glucose-6-phosphate requires 4 molecules of ATP and 2 molecules of GTP to proceed spontaneously. Gluconeogenesis is often associated with ketosis. Gluconeogenesis is also a target of therapy for type 2 diabetes, such as the antidiabetic drug, metformin, which inhibits glucose formation and stimulates glucose uptake by cells.[4] In ruminants, because dietary carbohydrates tend to be metabolized by rumen organisms, gluconeogenesis occurs regardless of fasting, low-carbohydrate diets, exercise, etc.[5]

Can dogs the poison ivy?
AlexFokin [52]

Explanation:

Though cases of a dog being affected by poison ivy are rare, if you have a canine companion with sensitive skin, you should keep him away from the plant, just in case. “After being in an area with poison ivy or oak, you should wash your dog,” Nold suggests.

Why are negative feedback loops used to control body homeostasis? <br><br> (Short answer)
liberstina [14]

Answer:

Homeostasis is defined as the state of body in which body maintains several chemical and physical changes inside the body affected by external factors.

Negative feedback loop includes a sensor, stimulus, control center, and effector which is used to control homeostasis.

A negative feedback loop is a reaction that reduce an excessive response and maintain the functions within the normal range. for example: if temperature and blood glucose level increases in the body, negative feedback loops control both the variables and maintain homeostasis.  

Hence, negative feedback loops used to control body homeostasis.

The point at which the nerves from the left side of the body cross over into the right side of the brain, and vise versa, is the
musickatia [10]

The given blank can be filled with medulla.  

The medulla also called the medulla oblongata is the segment of the brainstem that is factually the stem, which elongates from the brain. The medulla is positioned below the pons and above the spinal cord and is a major relay intersection for information conducted to and from the spinal cord and the brain. This section of the brain is a monitoring center for circulation and respiration.
