Answer:
B. The conditions in their muscles have become anaerobic.
Explanation:
In humans, cellular respiration occurs naturally in an aerobic condition (presence of oxygen) but anaerobic respiration can be adopted in specific or extreme cases. One of those cases is after or during a VIGOROUS EXERCISE.
What happens is that, after a vigorous exercise by an athlete, oxygen becomes insufficient in their muscle cells due to high consumption. Hence, their muscle cells switch to anaerobic respiration (lactic acid fermentation), which causes the build up of lactate in the muscle tissues. This lactate build up cause athletes to experience a painful and burning sensation in their muscles.
Hence, it all begins when "conditions in their muscles become anaerobic after an exercise".
7. What is transformation and describe how it has been done in a famous
experiment.
The shift in molecular biology is the genetic change of the cell resulting from the direct absorption and integration of the dna material rebusied external oxygen from its surroundings and its intake through the cell membrane. Transformation occurs naturally in some types of bacteria, but artificial means can also be affected in other cells

Question 3 of 5
When does an organism become a juvenile during its life cycle?
O A. After birth
B. Before sperm and egg cells form
O C. After development is complete
O D. Before gametes fuse
Answer:
B. Before sperm and egg cells form.
Explanation:
An organism become a juvenile during its life cycle before sperm and egg cells form. juvenile is a stage in which organism is immature and young. The y just enter into the young stage. Every animal has three basic stages in their life cycles that starts as a fertilized egg, developing into an immature juvenile, and then transforming into an adult. The first stage occurs when the fusion of sperm and egg cells occur whereas adult is the mature stage of that organism.

The enzyme lactate dehydrogenase is responsible for fermentation of pyruvate to form lactate. This process occurs in red blood cells and in muscle cells during intense exercise. Why is fermentation a necessary process for these cells to meet their energy needs
Answer:
Fermentation is a process that happens in the absence of oxygen and it involves the conversion of Pyruvate to lactate.
Cells in the body need constant energy supply to cater for the various demands of our everyday activities and to ensure that they function optimally.
Oxygen supply is an important factor in ATP generation and in cases where there is a lack of it the body system adjusts itself to produce the energy anaerobically. This usually involves the conversion of pyruvate to lactate which aids the breakdown of glucose thereby supplying it to cells of the body.
Plants as well as brown, green, and red algae show a basic life cycle which involves the alternation of generations between a(n) egg and a sperm. seed and a cone. spore and pollen. megaspore and a microspore. sporophyte and a gametophyte.
Answer:
The correct answer is ''sporophyte and a gametophyte''
Explanation:
Plants have a diplohaplon life cycle: a haploid adult plant, called a gametophyte, and a diploid adult plant, called a sporophyte. In green algae, the two generations, sporophyte and gametophyte, are independent and generally the same size. This type of life cycle is found not only in many multicellular green algae, but also in brown algae and red algae. In vascular seedless plants, including ferns, gametophytes, although still independent, are smaller in size than sporophytes. In seed plants, the gametophytic generation is further reduced and is totally dependent on the sporophyte.

Answer: true.
Explanation:
What is the fate of pyruvate in the cytoplasm when oxygen is absent
Answer:
Pyruvate is turned to lactate via a process called fermentation
Explanation:
Pyruvate is the product of the initial stage of cellular respiration called GLYCOLYSIS. Pyruvate is produced in the cytoplasm where glycolysis occurs. The fate of pyruvate i.e. what will eventually happen to pyruvate, is determined by the presence or absence of oxygen.
In the absence of oxygen i.e. anaerobic condition, pyruvate is converted into lactate in a process called FERMENTATION. The NADH produced during glycolysis is reoxidized to form NAD+ in the process.

Lichens look like moss. But they're actually two organisms-usually fungi and algae-that live together in mutualistic
relationship. The fungi provide sheltered place for the algae tO grow and reproduce. What do you think the algae offer that
the fungi can't do?
Answer:
The algae increase the autotrophy by offering photosynthesis to the fungi in the lichen organism.
A lichen is an organism consisting of a symbiotic association between a fungus (the mycobiont) and algae. The mushroom brings water and mineral salts. The alga produces, by photosynthesis, various organic compounds of which it gives a part to the mushroom.
Mass of the moon is 7.4x10^22 kg and its radius is 1740km, Calculate the value of acceleration due to gravity on the surface of the moon. *
Answer:
The gravitational acceleration in the surface of the moon is 1.63 m/s^2
Explanation:
The gravitational acceleration at a distance R of an object of mass M, is given by:
g = G*M/R^2
Where:
G is the gravitational constant.
G = 6.67*10^(-11) m^3/(kg*s^2)
We could think that all the mass of the moon is at its center, then at the surface of the moon, the distance will be equal to the radius of the moon, thus:
R = 1740km
But we want to work with meters, so remember that:
1km = 1000m
then:
1740km = (1740)*1000m = 1740000m
R = 1740000m
And the mass is just:
M = 7.4x10^22 kg
If we input all that in the gravitational acceleration equation, we get:
g = (6.67*10^(-11) m^3/(kg*s^2))*(7.4x10^22 kg)/( 1740000m)^2
g = 1.63 m/s^2
The gravitational acceleration in the surface of the moon is 1.63 m/s^2

When a muscle is stimulated repeatedly at a high rate, eliminating a relaxation phase, the amount of tension gradually increases to a steady maximum tension. This is called:_______
Complete tetanus occurs when the muscle is stimulated repeatedly at a high rate, eliminating a relaxation phase, the amount of tension gradually increases to a steady maximum tension.
What is Complete tetanus?A tetanic contraction is also called as tetanized state, tetanus, or the physiologic tetanus, the latter is used to differentiate from the disease called tetanus, which is a sustained muscle contraction that is evoked when the motor nerve which innervates a skeletal muscle emits action potentials at a very high rate than usual action potential production rate.
Complete tetanus is also called fused tetanus. It occurs when the frequency of stimuli increases still further than normal. In this case, the individual muscle contractions completely fuse to produce one large enough muscle contraction in the body.

discuss the characteristic of a grafted plant.
What is the answer with explaining
Answer:
Man (dimples and freckles) - FfDd
Woman (no dimples and no freckles) - ffdd
Child (no dimples and no freckles) - ffdd
Explanation:
According to this question, the possession of freckles (F) and dimples (D) are the dominant traits. The union of a man with dimples and freckles and a woman with no dimples and freckles (ffdd) gave rise to a child that has no dimples or freckles (ffdd).
Since the child has a recessive 'ffdd' genotype, it means that the father will likely have a heterozygous genotype (FfDd). Therefore, the genotypes of the three persons involved are;
- Man (dimples and freckles) - FfDd
- Woman (no dimples and no freckles) - ffdd
- Child (no dimples and no freckles) - ffdd

Why are theories stronger and more reliable than hypotheses
Answer:
A hypothesis is an educated guess that is made before research takes place. A theory is an explanation of the natural world and the universe. It explains facts that have already been proven true and is supported by data. A theory can be repeatedly tested and verified, and if proven true, makes the theory even stronger. Even if the theory is proven false, it is simply modified. This is why theories are much more reliable than hypotheses.
