Changes in internal body temperature are maintained by various systems in the body that maintain balance between the body and the external environment. Homeostasis can be defined as the biological phenomena that occur within the body to resist changes within it.
Negative feedback resists changes in the body caused by changes in external conditions. Some changes may occur in your body to stabilize it.

How does the body maintain homeostasis through negative feedback? Maintaining homeostasis through negative feedback is a constant activity throughout the body. The human body regulates body temperature through a process called thermoregulation. This keeps the body temperature within a certain range even if the ambient temperature changes significantly.

Can the human body maintain normal temperature?
The human body is able to maintain a normal temperature despite large fluctuations in outside temperature. Depending on the situation, you can experience 1 or 2 changes.

Answer: Robert Hooke

Explanation: I already take the test

Robert Hooke was not involved in solving the mystery of the configuration of the DNA molecule.

Robert Hooke saw little, box-like cavities, which he depicted and referred to as cells. He had stumbled across plant cells! Hooke's finding laid the groundwork for cell theory by revealing cells as the tiniest constituents of life.

DNA Molecule- Nucleotides are chemical building units that make up DNA. A phosphate group, the sugar group, and one of four different nitrogen bases make up these building components. Nucleotides are joined together into chains, with both the sugar and phosphate groups switching places, to create strands of DNA.

The definition of species is that the members are able to reproduce having viable offspring. Being a group of living organisms with similar characteristics and capable of exchanging genes and produce viable offspring.

The primary distinction between the two types is that endocrine glands discharge substances directly into the circulation, whereas exocrine glands deliver their products through a ductal system to an epithelial surface. The acinus, a small collection of cells at the start of glandular ducts, is where exocrine secretions are produced. Exocrine glands can be divided into subtypes according on how they secrete, the substance they produce, or even how they look.

What is the function of exocrine glands?

Exocrine glands provide a variety of purposes. Each has a specific role that is determined by the organ with which it is related. The production and release of compounds that help your body in some way is the primary function of all exocrine glands. They benefit your body by:

This cartoon now includes the locations of three genes. The positions have only been noted on one chromatid for simplicity's sake. Genes a and b would cross across with the least frequency (closest together on chromosome)

One of a chromosome's two identical halves that has undergone replication in order to facilitate cell division is referred to as a chromatid. The centromere, a constrictive area of the chromosome, serves as the connection between the two "sister" chromatids.

During meiosis and mitosis, chromatin fibers are used to make chromatids. When DNA is wrapped sequentially around skeletal proteins, the structure is known as a nucleosome and is referred to as chromatin. Chromatin fibers are even more densely wrapped nucleosomes. DNA can be compressed by chromatin to fit into the nucleus of a cell. Chromosomes are made of threads of condensed chromatin.

Explanation:

It depicts meiotic division because the process depicted is meiotic metaphase-I, in which pairs of chromosomes are aligned on the same plate rather than a single chromosome.

Cell division refers to the processes that take place when a cell divides into new daughter cells, while cell cycle refers to the duration of a cell. Meiosis or mitosis are both viable options for cell division. Meiosis involves the division of a cell into four smaller daughter cells as opposed to mitosis, which involves the division of a cell into two new daughter cells.

The biogeographic process due to which we discover a sister pair of birds on two islands (a blue species and a yellow species) is Natural selection.

Natural selection is a process in which more environment-adapted organisms tend to survive and reproduce more frequently than less environment-adapted ones. It happens when a species' genotype, or genetic makeup, undergoes selective modification. Natural selection is the term used to describe varied survival rates under different natural causes.

Natural selection was jointly discovered by Charles Darwin and Alfred Wallace in 1858 (Darwin & Wallace), but Darwin is credited as being the theory's primary proponent and is best known for his book On the Origin of Species (Darwin 1859).

Osmosis refers to water motion. 1) If there are more water molecules inside the cell, water moves out of the cell only. 2) If there are more water molecules outside the cell, water moves into the cell only. 3) If the number of water molecules inside and outside the cell are the same, water moves into and out of the cell in equal amounts.

Since I do not have the concentration of water inside and outside the cell, to answer this question I will porpose three scenarios. But first, let us review the osmosis concept.

Osmosis is a simple passive transport referred especially to water. These molecules can move between dilutions of different concentrations until reaching equilibrium.

Water molecules can freely move through a membrane from the most diluted side to the more concentrated one.

So, there are three possible scenarios,

1) There are more water molecules inside the cell than outside the cell.

This means that

Water molecules tend to move outside the cell until the number of molecules in the cell's interior and exterior are the same.

2) There are more water molecules outside the cell than inside the cell.

This means that

Water molecules tend to move inside the cell until the number of molecules in the cell's interior and exterior are the same.

3) The number of water molecules inside and outside the cell is the same.

In this case, water molecules will move into and out of the cell in equal amounts.

Now, you should check the number of water molecules in your example, and choose the correct option following these scenarios.
