Answer:
Autotrophs
Explination: They are called this because they use the energy and simple inorganic compounds to produce organic molecules.
<span>A human body is composed of muscles. Without it, the human body cannot function and will die. </span>
There are three types of muscle tissues: Skeletal muscle, Cardiac muscle, and Smooth muscle.
The skeletal muscle aids in the movement of the human skeleton. The 600 skeletal muscles make up 40 % of our body weight and are reliant on the signals released by our nervous system to start moving.
<span>Cardiac muscles are those muscles which encloses our hearts. They are involuntary muscles which pumps blood throughout our bodies by creating steady and rythmic pulsing. They also make our heart contract by producing electrical impulses. </span>
<span>Smooth muscles are found in the walls of blood vessels, respiratory passageways, and hollow organs. Its contracting movement is wavelike and it helps in the transfer of food through our stomachs or urine through our bladder. </span>
<span>These muscles responds to nerve impulses and other stimuli.</span>
Answer:

</h2><h2>

</h2><h2>
50 % males would be infected
</h2><h2>
50% male normal</h2><h2>
50% female normal,
</h2><h2>
50 female carrier.
</h2>
Explanation:
Hemophilia is an inherited disease and it follows an X-linked recessive pattern. The genes for hemophilia disease are located on the X chromosome. In males one mutated copy of the chromosome X is sufficient to cause the condition, because male contain only one gene. Female contain XX chromosome, so both the chromosome must have mutated for causing this disease.
According to study of Queen Victoria (1891-1901) of England, Alice's daughter Alix was X linked carrier and George V was normal male,
so if they got married, their children would be
parents genotype X X* XY
progeny
XX, XY, X*X, X*Y
50% males would be infected
50% male normal
50% female normal,
50 female carrier.
I'm guessing true, that's what my teacher says
Answer:
The history of net photosynthesis and transpiration per unit leaf area was determined for intact soybean leaves from their unfolding to senescence during flowering and pod filling on untreated (podded) and partially depodded plants growing in a glasshouse. Leaf diffusive resistances to CO2 were calculated and a water use efficiency parameter was derived (net mass of carbon dioxide fixed per unit mass of water transpired per millibar vapour pressure deficit). Net photosynthesis and transpiration behaved similarly through all stages of leaf development. A number of peaks were evident in these parameters. The first was associated with leaf expansion and occurred when the leaf reached its maximum area. The second peak coincided with flowering of the plant and later peaks occurred during pod filling. Stomatal and mesophyll resistances also exhibited similar behaviour during the life of the leaf; the possible causes of this linkage are discussed. Water use efficiency increased rapidly up to the time of full lamina expansion. Thereafter, it rose slowly or remained stable until leaf senescence approached, when the efficiency declined. Net photosynthesis and transpiration of leaves were very similar in both podded and partially depodded plants. It appears that to prevent a shortage of assimilate during flowering and pod filling, photosynthesis may be maintained or increased in some leaves and the response is not related to the number of pods available for filling. The increases in photosynthesis were correlated with both higher stomatal and mesophyll conductances. Mechanisms by which the plant may control leaf photosynthesis are discussed.
