Answer:

protons and neutrons

Explanation:

Protons and neutrons have a positive and neutral charge, respectively. They are in the nucleus, while the negative electrons orbit the nucleus.

Answer:

Protons, neutrons, electrons

Explanation:

If you're asking about subatomic particles.

Answer:

The number of protons in one atom of an element determines the atoms identity.

Answer:

3.)A person shivering when their body temperature is low.

7.)Ants moving within their mounds depending upon the time of day

1-A plant bending toward a light source.

.-Iguanas laying in the sunlight if their body temperature is low.

.-A unicellular organism beating microscopic hairs to escape a chemical pollutant in its environment

.-Birds migrating when seasons change.

The maintenance of relatively constant internal environment of an organism is called  Homeostasis.It is an automatic regulations of the body systems and organs controlled by the brain and some receptors, specific for certain body fluctuations.E.g Thermoreceptors Chemoreceptors etc.

The fluctuations in the body internal systems must be controlled within a narrow limits, for existence of living organism.The brain receives inputs from the receptors, and the outputs from the brain ensures the  homeostatic control.

The above examples are typical homeostatic responses by the organisms involved, because the inputs from the receptors  send signals to the brain ,and the organisms  responded to these with the example above.

Answer:

10.5minutes

Explanation:

DRT = 90%

Cells present = 10^6

Autoclaving = 1.5 minutes

Solution:

10^6(1.5)10^5(1.5)10^4(1.5)10^3(1.5)10^2(1.5)10^1(1.5)10^0(1.5)0=10.5

it would take it approximately 10.5 minutes to kill 10^6 of the cells.

If i should stop the heating process at 9 minutes this would have effect on some of the microbes as they are still present with 1 bacterium left which makes it not efficient.

Explanation:

Answer:

The digestive system produces different types of enzymes in order to convert proteins, fats and carbohydrates into smaller molecules and facilitate their absorption.

Explanation:

Once food is ingested, it must go through a process of digestion, which involves the conversion of food into smaller molecules, in order to facilitate its absorption at the intestinal level.

There are different enzymes, produced in the digestive system, for this purpose:

The main objective is to obtain the fundamental components of each food to be assimilated by the organism, via intestinal absorption.

Answer:

a theory cannot become a law

Explanation:

the difference between a scientific theory and a scientific law because a theory is an in depth explanation of an observed phenomenon. a law is a statement about an observed phenomenon or an unifying concept (i.e.: newtons law or gravity - no explanation on how it works or what it is just that it exists.)

Answer:

phospholipid

Explanation:

Phospholipids, triglycerides, fats, and oils are examples of a lipid. Therefore, option D is correct.

Fatty, waxy, or oily molecules are referred to as lipids. They are soluble in organic solvents but insoluble in polar solvents like water. Steroids, phospholipids, oils, and waxes are examples of lipids. They are usually referred to as fats and oils.

Since lipids may be broken down to provide significant amounts of energy, one of their primary biological purposes is the storage of energy. The structural elements of cell membranes and a number of the body's messengers and signaling molecules are also formed by lipids.

Cell membranes, cholesterol, blood cells, and the brain are just a few places where they can be found in the human body.

WHAT IS THE MAJOR EVOLUTIONARY ADVANTAGE TO PRODUCING AN AMNION?

The main evolutionary advantage of producing an amnion is that the embryos of the amniotic membrane,the amniotes are made available with their own aquatic environment,this in-turn resulted to a lesser dependence on water for it's maturation and development therefore allowing or giving room for the amniotes to branch towards environments that are drier.

WHAT FOES THAT MEAN GOR EMBRYONIC DEVELOPMENT OF THE ANIMAL PHYLUM AS COMPARED TO THE ANIMAL PHYLA?

The embryonic development of animal phylum is also known as embryogenesis.

It is the development of the embryo from the point of fertilization of an egg,(the ovum) by a sperm cell ,this makes the fertilized egg a diploid cell otherwise known as a zygote.

This zygote undergoes mitosis,a mitotic division known as cleavage and a differentiation resulting in a multicellular embryo.

This embryonic development of animal phylum comprises of 36 animal phyla.

Answer:

The last phase of cell division is cytokinesis. In this phase the cytoplasm of parent cell divides in to two cells called as daughter cells. It occurs during late stages of nuclear division.

The visible change of cytokinesis in an animal cell can be observed as formation of Furrow or Pucker on the cell surface.

Answer:

The bipedality

Explanation:

One of the things the discovered fossil signified was that human bipedality was more ancient than the large brain size because Lucy actually had a small skull which could indirectly be translated to small brain size.

NOTE: Bipedality can be described to mean the ability of an organism to move about with two legs. Hence, it must have been discovered that Lucy had two legs.
