In the human body, when the blood sugar level rises, a hormone known as insulin is released by the pancreas. This hormone speeds up the movement of sugar out of the blood, so the blood sugar level decreases and returns to equilibrium.This is an example of
gene expression.
a feedback mechanism.
natural selection.
a learned behavior

Answers

Answer 1

Answer:

The scenario described is an example of a feedback mechanism, which is the second option, as a feedback mechanism is a process in which the output or result of a system or process feeds back into the system and influences the input or process.

What is a feedback mechanism?

A feedback mechanism is a process in which the output or result of a system or process feeds back into the system and influences the input or process. In this case, the rise in blood sugar levels triggers the release of the hormone insulin from the pancreas, which then acts to lower blood sugar levels by increasing the movement of sugar out of the blood. This feedback mechanism is essential for maintaining the body's blood sugar levels within a healthy range. When blood sugar levels rise too high or fall too low, the feedback mechanism is triggered to bring the levels back to equilibrium.

Hence, The scenario described is an example of a feedback mechanism, which is the second option

what have scientist learned about the classification of amphibians, birds, and reptiles by studying their evolutionary relationships?

Answers

Scientists learned many things in studying and defining organisms or animals into group. The study behind this is called Taxonomy. This study is responsible for the classification of amphibians, birds, and reptiles. The study learned about the evolutionary relationships between the living and extinct organisms.

Answer:

Reptiles are more closely related to birds than amphibians. Reptiles and birds are so closely related that according to modern classification, they are part of the same group.

What base pairings normally occur during DNA replication

Answers

The base paring that occurs during DNA replication is Adenine to Thymine, Thymine to Adenine, Cytosine to Guanine, Guanine to Cytosine.

What base pairings normally occur during DNA replication?

During DNA replication, specific base pairings occur that ensure accurate and faithful duplication of the genetic information.

DNA consists of four nucleotide bases:

adenine (A),

thymine (T),

cytosine (C), and

guanine (G).

The base pairing rules are as follows:

Adenine (A) always pairs with Thymine (T).

Thymine (T) always pairs with Adenine (A).

Cytosine (C) always pairs with Guanine (G).

Guanine (G) always pairs with Cytosine (C).

Using at least three sentences, describe the process of weathering, and explain how it can happen physically orchemically?

Answers

Weathering is the process by which rocks, minerals, and other geological materials are broken down and altered over time due to exposure to the Earth's atmosphere and environmental factors.

What is weathering?

Physical weathering, also known as mechanical weathering, involves the physical breakdown of rocks into smaller fragments without any change in their chemical composition. This process is primarily driven by mechanical forces such as temperature changes, freeze-thaw cycles, wind, water, and pressure.

Chemical weathering is the process in which rocks and minerals undergo chemical reactions that lead to their decomposition and alteration. This type of weathering involves the interaction of rocks with substances in the atmosphere, such as oxygen, water, carbon dioxide, and acids.

Answer: Chemical weathering decomposes or decays rocks and minerals. An example of this is water and limestone. Organic weathering happens when plant break up rocks. One the rock has been weakened and broken up it is ready for Erosion. This happens when rocks are picked up and move usually by water. Mechanical weathering breaks up rocks, this usually happens when water gets into cracks, freezes and expands the rock

Which of the following senses is most closely related to balance? A. Touch
B. Smell
C. Hearing
D. Taste

Answers

C. Hearing

Ears are also responsible for balance, in the part of the Cochlea.

Here you will find a liquid-filled cavity that functions to maintain balance and movement.

Whenever a sound reaches the ear, it creates a sound wave that creates vibration in the eardrum. The pressure when high pushes the membrane inwards while low pressure sound waves helps the eardrum to come outwards.

These sound waves are then transduced when it reaches the cochlea where hair-like structures interprets the sensory information and is relayed to the brain.
