Answer:

Species vary globally, species vary locally, and species vary over time.

Explanation:

Darwin noticed three distinctive patterns of biological diversity.

Charles Darwin observed three patterns of biodiversity during his exploration on the voyage of the HMS Beagle and in his subsequent research:

Species Variation: Darwin noticed that within a particular species, there is a wide range of variation among individuals.

Geographical Distribution: Darwin observed that different regions of the world have distinct sets of plant and animal species.

Fossil Record: Darwin studied the fossil record and recognized that it contains evidence of extinct species that differ from those currently living.

Thus, these three patterns of biodiversity species variation, geographical distribution, and the fossil record were instrumental in shaping Darwin's theory of evolution by natural selection.

Answer:

These antibiotics bond to protein molecules on the existing wall and prevent the cell from adding any new material as the wall stretches. When the cell wall stretches too far, it becomes weak and eventually bursts, destroying the cell. Since animal cells don't have cell walls, they are not affected by penicillin.

Answer:

Molecules are two or more atoms chemically joined together

Compounds are two or more different elements joined together chemically(heteronuclear or homonuclear).

Explanation:

All compounds are molecules, but not all molecules are compounds. a molecule can be made of two atoms of the same kind, as when two oxygen atoms bind together to make an oxygen molecule, all compounds are made up of two or more different types of atoms.One that is used a lot is water(H2o)

Formally, osmosis is the net movement of water across a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration.

Explanation:

Hope it helps :P

osmosis is the net movement of water through a semipermeable membrane from an area of lower solute concentration to an area of higher solute concentration

Osmosis is defined as the passive process in which the molecules move from a region of higher concentration to lower concentration until the concentrations become equal on either side of the membrane with out expenditure of external energy.

Gases and supercritical liquids are solvent undergo the process of osmosis; It can be up two types such as Endosmosis where a substance in a hypotonic solution, the solvent molecules move inside the cell and the cell becomes turgid by a process  of deplasmolysis.

When a substance in a hypertonic solution, the solvent molecules move outside the cell and the cell becomes flaccid or undergoes plasmolysis. This is known as exosmosis.

it is because when breaking blood groups of parents they are (IAIO ) for mother and (IAIO) for the father , meaning both blood groups foe the parents has component (O) and during crossing of genes blood group O for a child can be a possible blood group.

Blood is distributed from the surface of a bone to deeper central canals through channels known as Haversian canals.

Haversian canals are small channels that run through the bone tissue, and they serve as the highways for blood vessels, nerves, and lymphatic vessels. They distribute blood and other essential nutrients to the bone tissue and allow for the removal of waste products.

These canals are surrounded by concentric layers of bone matrix, known as lamellae, and they help to maintain the structural integrity of the bone. The distribution of blood through the Haversian canals is essential for the health and maintenance of the bone tissue.

Answer:

These stimuli, called growth factors, are naturally occurring proteins specific to certain groups of cells in the body. They include nerve growth factor, epidermal growth factor, and platelet-derived growth factor.

Explanation:

Hope this helps.

Growth factors are defined as the proteins that bind to specific receptors, which activate the cascade of signal transductions. The growth factors lead to proliferation, apoptosis, and development.

Different types of growth factors stimulating the signal transduction are:

1. Nerve growth factor is controlled by the gene NGF. It provides the instructions to make the beta protein, which is important for the survival and development of the nerve cell.

2. Epidermal Growth Factor is a type of factor that stimulates cell development and cell proliferation. It generally stimulates the fibroblasts and epithelial cells.

3. Platelet-derived growth factor regulates cell division and growth. These factors help in healing and repairing the wound and walls of the damaged blood vessels.

Thus, the growth factors when bound to specific cell receptors control the various activities of the cells.

Wood is flammable, which means that it can burn when it is exposed to heat, oxygen, and an ignition source (such a spark or flame).

Thus, Nonflammable materials are those that do not readily ignite and do not burn even when exposed to high temperatures or flames.

Combustion Behaviour: During a fire, when wood is exposed to heat and oxygen, a combustion process takes place, releasing heat, light, and numerous combustion byproducts like carbon dioxide and water vapour.

The fire is maintained and can spread as a result of this procedure. Even when exposed to high heat or flames, nonflammable materials do not burn and do not support a fire.

Thus, Wood is flammable, which means that it can burn when it is exposed to heat, oxygen, and an ignition source (such a spark or flame).

The population growht rate is 32.602 % per year. Population growth can be calculated as = (births + immigrants) - (deaths + emigrants).

In this case, population growth is equal to = (34,560 births + 478 immigrants) - (2,310 deaths + 126 emigrants) = 32,602 new individuals per year

Total (original) population: 100,000 _____ 100%

                                             32,602  _____ X

In consequence, the population growth rate per year can be estimated by the following equation:

X = (32,602 x 100)/ 100,000 = 32.602 %

In reference to the options listed in the image, we can say that protein pumps are efficient because they can move two types of molecules, which makes option B correct.

A protein pump is a kind of protein, often found in the cell membrane, that has the capability to pump specific substances in and out of the cell. Most of the processes that happen at the cellular level are naturally optimized for efficiency, even when the process consumes energy, as is the case with the protein pump.

The reason that the protein pump is considered efficient lies in how it uses the energy. Despite being an active process that consumes ATP to function, protein pumps are considered efficient because they can move two types of molecules at the same time, using the same molecule of ATP. This allows the cell to get more done for the same amount of energy.
