The physical characteristics that all specimens have in common can be presence of cells, as there is no specimen given, let's take animals. A dichotomous key can be used to find the similarity.

A specimen can be anything that is displayed regarding the subject. In labs the specimens can be chemicals, animals, plants, any objects, etc.

Specimens are displayed to learn about them, to see the actual version of that animal that can not be seen easily.

Explanation:

VEGAN DIET

A Vegan diet refers to diet that contain food from plants such as maize , beans, rice, wheat e.t.c It is mainly plants source and does not contain animal source.

But MILO is also Plant based energy and it contains several vitamins and minerals to help grow a healthy body: It contain Vitamins B2 and B3 which help to support effecient energy release in the body. It contain Essential nutrients like iron, zinc which are very minute

in plant based diets. Milo contain milk which is of animal source.

Therefore, Milo product is not suitable for a vegan diet because it contains milk solids which is derive from animal source.

The biological referred to as Adaptation makes living beings to adjust in exhausting atmosphere.

Adaptation, in biology, is that the method by that species measure suitable their several atmosphere, thanks to Natural Selection’s method ensuing into patrimonial variation over many generations.

According to Evolution, Adaptation method is that the process underneath that organisms suits the present atmosphere in conjunction with the modifications thanks to change in atmosphere.

Adaptation is connected with the idea of evolution that was propounded by Darwin and Wallace.

According to Wallace, the evolution of organisms was supported 2 factors: Adaptation and dynamic atmosphere.

To develop the idea of evolution by survival, Wallace and Darwin targeted not solely on straightforward adaptation however additionally proceeded more to clarify however organisms adapt and evolve.

Biologically Adaptation will be in 3 forms:

- Psychological kind

- generative kind

- sequence Frequency

Psychological form- associate degree animal or plant adapt by adjusting consistent with its immediate atmosphere.

Example- modification in temperature or metabolism with a rise in altitude

Reproductive form- method of adaptation thanks to genetic variations among people that is customized i.e. having larger success in—a specific environmental context.

Gene frequency- the method of adaptation happens through associate degree ultimate modification within the sequence frequency relative to blessings bestowed by a selected characteristic, like the coloration of wings within the moths.

Organisms will adapt to associate degree atmosphere in several ways in which. they will adapt biologically, which means they alter body functions

Example- individuals living at high altitudes have evolved changes in their body chemistry and may survive at high altitudes for a brief time as a result of their bodies raise their levels of hemoprotein.

They can additionally exhibit activity adaptation.

Example of activity adaptation is however emperor penguins in Antarctica foregather to share their heat within the middle of winter.

The theory of survival was given by Darwin in 1859.

Natural selection is that the method through that populations of living organisms adapt and alter.

Individuals in an exceedingly population square measure naturally variable, which means that they're all completely different in some ways in which.

This variation means some people have traits higher suited to the atmosphere than others. people with adaptive traits—traits that provide them some advantage—are a lot of seemingly to survive and reproduce.

These people then pass the adaptive traits on to their offspring. Over time, these advantageous traits become a lot of common within the population.

Through this method of survival, favorable traits square measure transmitted through generations.

Natural selection will cause phylogeny, wherever one species offers rise to a replacement and clearly completely different species. it's one among the processes that drives evolution and helps to clarify the range of life on Earth.

Aquaporins result in a combination of positive charges intracellularly and negative charges extracellularly

What are Aquaporins?

Aquaporin is a group of membrane proteins found in cell membranes and selectively permit water to pass into and out of the cell. Also known as water channels, aquaporins are integral membrane pore proteins. Aquaporins are found in plants, bacteria and animals. They are observed in the vacuolar membranes and plasma membranes. The basic function of most aquaporin is to transport water across cell membranes in response to osmotic gradients created by active solute transport. Aquaporins enable passive transport which means they allow the movement of molecules across a cell without using energy.

Stem cell research is a controversial subject because they are human embryonic stem cell (hESC), and obtaining stem cells involves the destruction of human embryos

Explanation:

The inner cell mass of a 5 to 7-day-old blastocyst can be used to generate pluripotent stem cell lines. Human embryonic stem cell investigation, on the other hand, is morally and politically fraught since it encompasses the killing of human embryos.

Stem cells are the primary raw material of the body, the cells that give rise to every other cells with specialized functions.

Under the right circumstances, stem cells differentiate to form the most cells known as daughter cells in the body or in a research lab.

Stem cells are mostly found in bone marrow. This is how they divide in order to produce new blood cells.

Once mature, blood cells end up leaving the bone marrow and reach the bloodstream. A small number of immature stem cells enter the bloodstream.

Bone Marrow has long been thought to be the best source of stem cells.

Previously, if a patient required a stem cell transplant but didn't have access to umbilical cord blood stem cells, they earned a bone marrow transplant.

Thus, this is the reason to have stem cell research as a controversial subject.
