7. Apply: Look carefully at the picture below and you will see an insect called a
katydid. Katydids evolved from grasshoppers through natural selection. Use
what you have learned to explain how this could have happened.
Answer: This description is an example of camouflage adaptations.
Explanation:
The grasshoppers are the insects which feed on plant parts and they are able to change their color with respect to their surrounding environment. For example, if they are living on the brown tree trunk they change their color to brown and on the green grass or green leaves they change to green to remain undetected by the predators. This way they are able to camouflage their predators this adaptation allows their survival in their environment with due course of natural selection. The phenotypic trait that is grasshopper is able to change its color increases the chances of survival of the grasshopper. Kaytids have evolved from grasshoppers means they have camouflage traits as that in parent grasshopper species. They have structure which blends with surrounding environment, that is they have wings that mimic that of pattern of leaf venation, also when they change the color to brown the shape of the body appears to be as that of stem. This structural adaptation help them to camouflage their predators.

QUESTION 1
Which of the following statements are true of arteries and veins? (Read carefully and select all of the correct statements.)
A. Venous anastomoses ensure that oxygenated blood will get to tissues.
B. The endothelium of both arteries and veins contributes to the prevention of abnormal clotting.
C. The smooth muscle layer of veins is thicker than that of arteries because veins are farther from the heart.
OD. Only veins have valves, which keep the blood moving between heartbeats.
E. The fibrous connective tissue layer of arteries is relatively thin because the blood is moving fast.
OF Arterial anastomoses ensure that blood will be able to return to the heart.
Answer: B, D
Explanation:
Is this a Med School K Question? The endothelial lining of blood vessels have many functions, including, preventing clotting. Veins carry blood that has very low pressure and have valves to control the one-way flow of blood. The rest are false. Only the pulmonary vein carries oxygenated blood. Arteries have more smooth muscles than veins. The anastomoses are present to act as alternative pathways to reach cells.

Assignment 1
-The cell is the smallest unit of life. All living things are made of cells.
A) What are the three principles of the cell theory? And explain each in details.
-Present-day mitochondria and chloroplasts probably evolved as a consequence of early endosymbiosis: the ancestor of the eukaryotic cell engulfed a bacterium, and the bacterium continued to function within the host cell.
B) What is the Endosymbiont theory? What is the evidence supporting this theory?

1. What is a convection current?
2. How do thermometers work?
Answer:
1.a current in a fluid that results from convection.
2.measures temperature through a glass tube sealed with mercury that expands or contracts as the temperature rises or falls.
Explanation:
Answer:
1.A convection current is a process that involves the movement of energy from one place to another. It is also called convection heat transfer. What is the reason that makes you feel hotter when placing hands above a campfire or when sitting next to it? Or, why is the movement of liquid so rapid when water is boiled in a pot? These things happen as a result of the Convection Currents.
Explanation:
2. A thermometer measures temperature through a glass tube sealed with mercury that expands or contracts as the temperature rises or falls. ... As temperatures rise, the mercury-filled bulb expands into the capillary tube. Its rate of expansion is calibrated on the glass scale.
What is the main reason to put a telescope in space?
A.
It is much closer to the stars.
B.
It can receive star light that cannot reach Earth.
C.
Light reaching it is not affected by the movement of air.
D.
It can detect objects behind the moon.
Answer: D
Explanation:
The main reason we put telescopes into space is to get around the Earth's atmosphere so that we can get a clearer view of the planets, stars, and galaxies that we are studying. Our atmosphere acts like a protective blanket letting only some light through while blocking others.

Explanation:
The DNA during interphase is in _____ strands called _____
The Minimal Chromosome To enable it to be transmitted intact from one cell generation to the next, the linear DNA molecule of a eukaryotic chromosome must have appropriate nucleotide sequences making up three special kinds of regions: origins of replication (at least one), a centromere, and two telomeres. What would happen if such a chromosomal DNA molecule somehow lost: a) all of its origins of replication
Answer:
The chromosome wouldn’t be able to replicate
Explanation:
Without an origin of replication, the chromosome could not be copied prior to mitosis.

QUESTION 1 Genetic information has become part of our culture and it is difficult to tell the difference between unmodified and genetically modified food sources such as plant and animals. After reading this module’s material regarding vectors in biotechnology, consider the potential for nanotechnology and scientific advancement. Research nanotechnology and its potential use in biotechnology. In one or two paragraphs, explain the potential advantages and disadvantages of nanotechnology in health care, agriculture, or industry and discuss whether you would or would not support further research.
Answer:
Nanotechnology is a field of producing materials and devices from atoms and molecules.
Explanation:
Nanotechnology is a field that concerned with producing materials and devices from atoms and molecules. A nanometer is one-billionth of a meter in size. Nanotechnology can be used to “recognize” the cells of interest which allows associated drugs to reach diseased tissue without damaging healthy cells. Nanotechnology produces new and faster kinds of computers, more efficient power sources and more effective medical treatments. Main disadvantages include threats to security, privacy, health and the environment. More research must be done in this field to get more benefits from it.

Which protein is damaged at the nerve endings during mercury toxicity
a. keratin
b. tubulin
c. pilin
Answer:
b. tubulin
Explanation:
Tubulin is a superfamily of proteins that make up microtubules who have many functions including intracellular trasport of neuron's vescicles
Tubulin protein is damaged at the nerve endings during mercury toxicity.
What do you mean by Mercury Toxicity?Mercury toxicity occurs when an individual is highly exposed to mercury.
The inhalation of mercury vapor can produce harmful effects on the nervous, digestive and immune systems, lungs, and kidneys, and may be fatal. This is considered as one of the severe toxicity that a person suffers.
Tubulin proteins are a very important class of proteins that helps in the formation of microtubules that have numerous functions in our body including the cytoskeletal arrangement of cells, intracellular transport of neuronal vesicles. And when a person suffers from mercury toxicity, such proteins are damaged and result in improper conduction of nerve impulses.
Therefore, Tubulin protein is damaged at the nerve endings during mercury toxicity.
