B. the Sun appears lower in the sky than during other seasons.
D. the Sun rises in the Northeast and sets in the Northwest.
On the northern hemisphere the north is to the left, the Sun rises in the east (far arrow), culminates in the south (to the right) while moving to the right and sets in the west (near arrow). Both rise and set positions are displaced towards the north in summer, and towards the south for the winter track.

These microbes are usually adapted to their environment and this is why they are found in virtually all ecosystems. You will find bacteria even at the bottom of deep ocean beds deep and in geothermal vents, hypersaline water and very cold regions (such as polar regions). Fungi which vary widely in size from microscopically small to the largest organisms such as mushrooms are also found in virtually all environments on earth. They are nonetheless different species of these groups adapted to their environments.
Thus the response above i.e., "Option b" is right.

Answer:
b. grasshopper effect
Explanation:
Persistent Organic Pollutants or POPs are organic chemicals that cause a lot of damage to environment and living beings. They are generally industrial chemicals or pesticides for example, DDT. They are toxic and not degraded easily. They tend to get accumulated in living tissues and increase in concentration as we move upwards in a food chain.
When POPs are transported to areas far from their original site, the phenomena is called as grasshopper effect. They are carried by wind in atmosphere and finally settle down on land from where they evaporate again to enter the atmosphere. Thus, the cycle continues. Eventually, they can reach to an area thousands of kilometers away from their original source.
I. ActA binds to the Arp2/3 complex
II. E. Coli in which ActA is expressed moves in host cell cytosol
III. Listeria lacking the ActA gene fail to move inside the host cell cytosol.
IV. ActA has 3 transmembrane domains
V. Arp2/3, when activated, nucleates a branched actin network
A. I and II
B. II and III
C. I and III
D. III and IV
E. I and V
Answer:
The correct answer is option B. "II and III".
Explanation:
In order to prove that ActA protein of Listeria is necessary and sufficient for bacterial movement within its host cell a series of results in transformed Listeria and transformed E. Coli must be obtained. First, if Listeria lacking the ActA gene fail to move inside the host cell cytosol it will prove that ActA is necessary for bacterial movement. Second, a transformed E. Coli that expresses ActA should be able to move in host cell cytosol. Wild type E. Coli does not expresses ActA, if ActA alone makes E. Coli able to move in host cell cytosol it will prove that ActA is sufficient for bacterial movement.
