Answer:

6. integral proteins

7. down; concentration

8. active transport

9. osmosis; pinocytosis

Explanation:

An integral protein is a protein that is permanently attached to a biological membrane. Some examples of integral membrane proteins include, for example, the insulin receptor, cell adhesion proteins (e.g., integrins), glucose permease, etc. Diffusion, also known as passive transport, refers to the process by which a substance/molecule tends to move from an area of high concentration to an area of low concentration. Moreover, osmosis is a type of diffusion by which a solvent (e.g., water) moves across a semipermeable membrane from a region of lower concentration to a region of higher concentration. Active transport refers to the movement of molecules/substances across a biological membrane against a concentration gradient. There are two types of active transport: primary active transport and secondary active transport. The primary active transport depends on a source of energy (e.g., ATP) for movement, whereas secondary active transport depends on electrochemical gradients to transport substances with the help of membrane transport proteins (i.e., cotransporters). Active transport involves ATP pumps that move ions into and out of the cell. Finally, endocytosis is the process by which cells absorb external material by engulfing them in transport vesicles, whereas pinocytosis refers to a type of endocytosis ​involving fluids that contain many solutes.

Answer:

true

Explanation:

you should never proceed with sexual advance, or any advance really without a for sure verbal consent given.

In a strictly physical sense, the only difference between thermal energy and heat is that heat is currently in transit. For example, the warmth radiating from a fire.

While heat is a “path function”, thermal energy can be a “point function” as it can have a defined value at a specific state.  Numerically,  Δ(Thermal Energy) = Heat Exchanged.

B: Sugar

Explanation:

Answer:

Although  the  light  dependent  reactions  of photosynthesis     are    not     affected     by changes in temperature, the light independent   reactions  of   photosynthesis are dependent  on  temperature.  They  are reactions  catalysed  by  enzymes.  As  the enzymes approach their optimum temperatures  the  overall  rate  increases.  It approximately   doubles   for   every   10°C increase    in    temperature.    Above    the optimum  temperature  the  rate  begins  to decrease, as enzymes are denatured, until it stops.

Explanation:

At  low  light  intensities,  as  light  intensity increases,the  rate of  the  light-dependent reaction,and   therefore   photosynthesis generally, increases proportionately (straight    line    relationship).    The    more photons  of  light  that  fall  on  a  leaf,  the greater     the     number     of     chlorophyll molecules  that  are  ionised  and  the  more ATP   and   NADPH   are   generated.   Lightdependent  reactions  use  light  energy  and so    are    not    affected    by    changes    in temperature.As light intensity is increased further, however, the rate of photosynthesis is eventually  limited by some other factor. So the rate plateaus. At very high light intensity, chlorophyll may be damaged and the rate drops steeply (not shown in the graph).Chlorophyll ais used in both photosystems. The wavelength of light is also important. PSI absorbs energy  most  efficiently  at  700  nm  and  PSII  at  680  nm.  Light  with  a  higher  proportion  of  energy concentrated in these wavelengths will produce a higher rate of photosynthesis.An    increase    in    the    carbon    dioxide concentrationincreases  the  rate  at  which carbon  is  incorporated  into  carbohydrate in  the  light-independent  reaction,  and  so the    rate    of    photosynthesis    generally increases until limited by another factor.As    it    is    normally    present    in    the atmosphere  at  very  low  concentrations (about  0.04%),  increasing  carbon  dioxide concentration  causes  a  rapid  rise  in  the rate  of  photosynthesis,  which  eventually plateaus   when   the   maximum   rate   of fixation is reached.

Tropical wet and dry climate is typically observed within the tropics. The tropics are two lines of latitude at 23.5° north and 23.5° south of the Equator. Land within this area obtains direct sunlight throughout most of the year.

Answer: A semi-permeable membrane is that which only allows certain

               substances to pass through.

Answer: A semipermeable membrane is a layer that only certain molecules can pass through. Semipermeable membranes can be both biological and artificial. Artificial semipermeable membranes include a variety of material designed for the purposes of filtration, such as those used in reverse osmosis, which only allow water to pass. The biological membranes of cells are created by two sheets of phospholipid, which contain a lipid tail attached to a polar head. The tail regions of each sheet cluster together, while the heads of the molecules point outward. The polar heads point both outward toward the environment of the cell and inward toward the cytosol. In this way, a hydrophobic region of lipid tails separates the two bodies of solution. This can be seen in the image below.

Members of the same species compete with one another within their own species, hence option A is correct.

It demonstrates the adaptability of the species. Members of various species compete with one another across interspecific boundaries. It might result in the extinction of one species or the specialization of both.

In a population, individuals develop, procreate, and pass away. The needs of individuals within a population for survival, growth, and reproduction are quite similar. The result is frequently intraspecific competition.

The fitness of both populations is impacted by competition. The investment of resources (energy, time, and matter) in competition or avoidance of it diminishes the availability of these resources and has a negative impact on the population's ability to reproduce.

Therefore, option A is correct.

Answer: C. scorpions have changed as a result of natural selection

Explanation:

The text tells us that scorpions today are now smaller than they were in the past. This means that the scorpions have changed since then i.e. they have evolved.

The primary reason for evolution is natural selection which refers to a situation whereby only the organisms that are better adapted in their species survive.

The conclusion that can be drawn from this research therefore is that we have smaller scorpions today because they stood a better chance of survival than the larger ones and so survived whilst the larger ones died out.

Answer:

the answer is D

Explanation:

Rocks break down into smaller pieces through weathering. Rocks and sediment grinding against each other wear away surfaces. This type of weathering is called abrasion, and it happens as wind and water rush over rocks. The rocks become smoother as rough and jagged edges break off.

Reproduction is the second ability.

Explanation:

Conduction, convection and radiation are the modes of heat transfer:

Conduction:

Microscopic level of heat transfer

Also called as thermal diffusion(takes place due to atomic vibrations) and is highly invisible

Primarily occurs in solid-solid systems and stagnant liquids

Convection:

Macroscopic level of heat transfer

Primary occurs in fluids(involves bulk movement of fluids)

2 types of convection are possible — with external source of energy (forced convection) and without external source of energy (free convection)

Radiation:

Transfer occurs through electromagnetic waves

No medium is required unlike conduction and convection. Radiation can occur even in vacuum.

These are different processes of transferring energy from one place to another.

Radiation is the sunlight and (heat). It travels as electromagnetic wave and does not need matter to transfer energy. Hence radiation is the only mode of transferring energy in vaccuum, for example, light of visible and invisible wavelengths reaches from the sun and other stars as electromagnetic radiaton. Human body emits heat wave as radiation.

Convection and conduction refers to energy transfer through the motion of matter. The difference is how the molecules of matter move during the energy transfer.

Convection is that mode of energy transfer when matter also transfer from one place to another during energy transfer. Molecules of liquids and gases can move. So convection occurs in liquids and gases. It is visible when water is boiled on a gas burner.

Molecules of solids are too tightly bound to move. They vibrate about some average positions in space. Conduction is that mode of energy transfer when matter on average is not transferred from one place to another. Propagation of sound through solid wall is an example.

Answer:

Cell

Explanation:

Sodium and potassium ions are essential for muscle contractions of the heart, and the ions are transported using a pump, which obtains energy from the breaking of ATP molecules, this action requires the expenditure of energy, so sodium and potassium ions are transported using active transport.

Sodium and potassium ions play a crucial role in muscle contractions, including those of the heart, and to maintain the appropriate concentration of these ions inside and outside the cell, the body uses a protein pump called the sodium-potassium pump, which is an active pump. It requires energy to move substances across cell membranes; the pump uses the energy released by the breakdown of ATP molecules to change its shape, transport the sodium and potassium ions across the membrane, and regulate the muscle contraction.

Hence, the ions are transported using a pump, which obtains energy from the breaking of ATP molecules, this action requires the expenditure of energy, so sodium and potassium ions are transported using active transport.

The external organs include the penis, scrotum and testicles while on the other hand, internal organs include the vas deferens, prostate and urethra. The male reproductive system is responsible for sexual function, as well as removal of waste material from the body.

Answer:

helped replace earlier views based solely on observed phenotypes

Explanation:

The study of human variation has shown that individuals from different populations (previously erroneously considered as geographic races) are often genetically more similar than individuals from the same population. In consequence, the evolutionary approach for understanding human variation has enabled us to discard the biological race concept based solely on observed phenotypes in order to provide a more realistic variation concept associated with evolutionary human development. From this perspective, it has been possible to confirm that 1-there are no human subspecies and 2- the concept of human races is not scientifically suitable to describe human variation.

Answer: c. Air pollution

Explanation:

There was a heatwave in Europe during the early years of the 21st century that killed tens of thousands across the continent and thousands in France.

Air pollution was blamed for having made the situation worse because the pollutants in the air acted to prevent heat from escaping back into the atmosphere which led to increased heat on ground and therefore a heat wave.

Answer:

Aorta and vena cava are two main types of blood vessels attached to the heart. The main difference between aorta and vena cava is that aorta carries oxygenated blood whereas vena cava carries deoxygenated blood. Aorta is the main artery that leaves the heart through the left ventricle. It supplies oxygenated blood throughout the body. Two types of venae cavae supply blood to the right atrium of the heart. They are superior vena cava and inferior vena cava. Superior vena cava drains deoxygenated blood from the head, arms, and other upper parts of the body while inferior vena cava drains that from the lower parts of the body.
