Why can’t penguin fly?
Answer:
No they cannot fly
Explanation:
Penguins dont have any feather to fly with
Answer:
Well, in a sense they really do fly, only through the water, not through the air. Their wing bones are fused straight, making the wing rigid and powerful like a flipper. Penguins don't really need to fly because they dive deep, and swim so that they can catch their prey. Their bodies have huge fat supplies, heavy muscles, and densely packed feathers. There’s no way they could fly with such short wings and heavy bodies.

Which of the following illustrates the principle of induction in invertebrates?
A. In an embryo, the presence of a notochord beneath the ectoderm results in the formation of a neural tube.
B. A neuron synapses with another neuron via a neurotransmitter.
C. Eye muscles constrict in response to light.
D. Secretion of TSH stimulates the secretion of thyroxine.
E. The maternal parent induces spontaneous expression of recessive genes.
Answer:
A
Explanation:
A
How does the ectoderm that will make up the future eye know to develop into an eye? The cells are "told" to develop into an eye because the nearby retina releases chemical signals that direct the development of the cells. This process is called induction. Choice A depicts a similar situation. The notocord releases chemical signals that tell the overlying ectoderm that it is time for it to become the neural tube. None of the other choices depict the process of induction.

Based on the information in the table, which of the following best explains why this bug population has changed since the introduction of the invasive plants?
o The bugs are unable to feed on native fruits.
Bugs with longer mouthparts have a survival advantage.
Bugs with smaller body lengths have a helpful adaptation.
o The bugs have started cross-breeding with a larger species.
The bug population has changed since the introduction of the invasive plants the bugs are unable to feed on native fruits.
Why the population of bug decrease?The population of bug decrease because the invasive plants reduce the population of native plants on which the bug feed. If the food for the bug decreases then the population of the bug is also decreases.
So we can conclude that the bug population has changed since the introduction of the invasive plants the bugs are unable to feed on native fruits.

Hormos
Carbon dioxide
Oxygen is carried from systemic capillary blood to the perivascular tissues
Systemic capillary flow.Systemic circulation blood flow help to carry oxygenated blood from the left ventricle passing through the arteries, to the capillaries in the tissues of the body. The deoxygenated blood returns from the tissue capillaries through a system of veins to the right atrium of the heart.
Therefore, Oxygen is carried from systemic capillary blood to the perivascular tissues

Which of the following is a distinction between the Krebs cycle in eukaryotes and prokaryotes?
A. Prokaryotes do not use acetyl CoA.
B. The process occurs in the cytoplasm of Eukaryotes.
C. The process occurs in the mitochondria of Eukaryotes.
D. Eukaryotes do not produce carbon dioxide.
E. Prokaryotes do not produce FADH2.
Answer:
C. The process occurs in the mitochondria of Eukaryotes.
Explanation:
In eukaryotes: glycolysis takes place within cytosol, Krebs cycle within mitochondrial matrix & ETC within inner mitochondrial membrane. Prokaryotes undergo binary fission(only cytokinesis) & conjugation.Prokaryotes undergo binary fission(only cytokinesis) & conjugation. Eukaryotes perform mitosis, meiosis(both karyokinesis and cytokinesis).Therefore in prokaryotic cells, the citric acid cycle occurs in the cytoplasm; in eukaryotic cells, the citric acid cycle takes place in the matrix of the mitochondria.
Acetyl-CoA reacts in the first step of the eight step sequence of reactions that comprise the Krebs cycle, all of which occur inside mitochondria of eukaryotic cells. While the Krebs cycle does produce carbon dioxide, this cycle does not produce significant chemical energy in the form of adenosine triphosphate (ATP) directly, and this reaction sequence does not require any oxygen. Instead, this cycle produces NADH and FADH2, which feed into the respiratory cycle, also located inside of the mitochondria. It is the respiratory cycle that is responsible for production of large quantities of ATP and consumption of oxygen. In addition, the respiratory cycle converts NADH and FADH2 into reactants that the Krebs cycle requires to function. Thus, if oxygen is not present, the respiratory cycle cannot function, which shuts down the Krebs cycle. For this reason, the Krebs cycle is considered an aerobic pathway for energy production.
