6. Bug Protection
(1) Almost all insects will fee if threatened. (2) Many insects, however, have more specialized means of defense. (3)
Roaches and stinkbugs, for example, secrete foul-smelling chemicals that deter aggressors. (4) Bees, wasps, and some
ants have poisonous stings that can kill smaller predators and cause pain for larger ones. (5) The larvae of some insects
have hairs filled with poison. (6) If a predator eats one of these larvae, it may suffer a toxic reaction. (7) Insects that
defend themselves by unpleasant or dangerous chemicals gain two advantages. (8) On one hand, they often deter a
predator from eating them. (9) On the other hand, predators learn not to bother them in the first place.
(10) Other insects gain protection by mimicry, or similarity of appearance. (11) In one kind of mimicry, insects with similar
defense mechanisms look alike, and predators leam to avoid them all. (12) Bees and wasps mimic each other in this
way. (13) In another kind of mimicry, insects with no defenses of their own mimic the appearance of stinging or bad-
tasting insects (14) Predators avoid the mimic as well as the insect with the unpleasant taste or sting (15) For example,
syrphid flies look like bees but do not sting.
(16) Another kind of defense based on appearance is camouflage, or the ability to blend into surroundings. (17) Many
kinds of insects and animals have distinctive color markings that make them difficult to see. (18) Predators have trouble
locating prey that looks like its background. (19) An insect is more likely to survive and produce offspring if it is
camouflaged than if it is not.
Answers
Insects employ various strategies to protect themselves from predators. They may use chemical defenses, such as secreting foul-smelling chemicals or possessing poisonous stings. Additionally, some insect larvae have poisonous hairs that can cause toxic reactions in predators. Insects that rely on unpleasant or dangerous chemicals gain two advantages: deterring predators from eating them and teaching predators to avoid them altogether.
The passage describes various defense mechanisms employed by insects to protect themselves from predators. Insects have evolved a range of strategies to deter or escape from threats.
These strategies include chemical defenses, mimicry, and camouflage. Chemical defenses involve the secretion of foul-smelling chemicals or the possession of poisonous stings, which discourage predators from attacking or eating them.
Mimicry involves insects with similar defense mechanisms resembling each other, leading predators to avoid them altogether. Some insects mimic the appearance of other species with unpleasant tastes or stings, deterring predators.
Camouflage is another defense mechanism, enabling insects to blend into their surroundings and make it difficult for predators to spot them. These defense mechanisms increase the chances of survival and successful reproduction for insects, as they are better equipped to defend themselves against potential threats.

Answers
The process in the image is transcription. This is mRNA synthesis and occurs in the nucleus. mRNA copies a segment of DNA and carries this information to the cytoplasm to synthesize new proteins.
What is transcription?
Transcription is the mRNA synthesis process. It occurs in the nucleus and is the previous stage before protein synthesis (translation).
During transcription, fragments of DNA molecules are used to copy the desired sequence that carries the necessary information to grow the new proteins.
In the nucleus, the DNI molecule uncoils and forms the transcription bubble, separating the two strands.
At this point, two fragments of DNA can be identified, the coding strand and the template strand.
The coding strand –non-template strand- goes in direction 5' to 3',The complementary strand -template strand- grows in direction 3' to 5'.The template strand acts as a mold for mRNA growth. This is the chain that is complemented by the mRNA.
On the other hand, the coding strand (non-template) carries the same nucleotidic sequence as the new mRNA. The only difference is that instead of Uracyls (which are only present in RNA molecules), it has Thymines (which are only found in DNA).
RNA polymerase is in charge of reading the original DNI template strand and for mRNA synthesis.
mRNA molecule grows complementing DNA base sequences. This is,
DNA mRNA
adenine ⇔ uracil
guanine ⇔ cytosine
thymine ⇔ adenine
cytosine ⇔ guanine
Once mRNA synthesis is over, the molecule leaves the nucleus to start the translation process in the cytoplasm.
Note: I could not find the image, but the labels suggest this is a transcription process.

Answers
The sentence that best describes the temperatures of a city located along a windward coast is C.Cooler summer temperatures than an inland location at the same latitude.
What is affected by a body of water's temperature?A city on a windward coast experiences cooler summer temperatures than an area inland at the same latitude.
In comparison to an inland site at the same latitude, a city positioned along a windward coast will experience (b) lower summer temperatures. This area's predominant breeze originates from the lake, which will always have a moderating effect (both warmer in the winter and cooler in the summer). Climate, salt intake, hormone levels, carbohydrate intake, degree of physical activity, and some substances like alcohol and caffeine can all have an affect on total body water content.
Temperature is crucial because it affects the chemistry of water. At greater temperatures, chemical reactions typically proceed more quickly. Higher temperature water, especially groundwater, can dissolve more minerals from the underlying rock and will consequently have a higher mineral content.

Which organisms can reproduce using the process of fragmentation
Answers
Fragmentation is a form of asexual reproduction and is seen in annelids, fungi, cyanobacteria, sponges, and flatworms.
In Fragmentation, an organism divides itself into a number of fragments. It occurs when an organism completely breaks down independently irrespective of the other parts. Each one of these fragments matures into fully grown adults that are clones of the original organism.
Asexual reproduction usually involves the participation of a single parent alone can produce new offspring. The newly produced individual is genetically identical to one another and its parent. Both multicellular and unicellular organisms divide by fragmentation which is asexual reproduction.
Fragmentation is the most common method of reproduction in lower invertebrates. It is seen in many organisms including filamentous cyanobacteria, algae, lichens, molds, many plants, and animals such as flatworms, annelid worms, sponges, and sea stars.

The organisms that can reproduce by fragmentation are Option d Sponges and Sea anemones.
Fragmentation is a form of asexual reproduction in which an organism breaks into two or more fragments, and each fragment develops into a new individual. Both sponges and sea anemones are examples of organisms that exhibit this mode of reproduction.
Sponges are simple multicellular animals that lack true tissues and organs. They possess a porous body structure, and when a sponge is fragmented, each fragment has the potential to develop into a new sponge through regeneration. These fragments contain specialized cells called archaeocytes that can differentiate into various cell types required for the formation of a new sponge.
Sea anemones, on the other hand, are marine animals belonging to the phylum Cnidaria. They have a cylindrical body with tentacles surrounding their mouth. When a sea anemone is fragmented, each piece can regenerate into a complete individual. The process involves the differentiation of cells within the fragments, leading to the development of new tentacles, body parts, and eventually a mature sea anemone.
Both sponges and sea anemones have remarkable regenerative abilities, allowing them to reproduce through fragmentation. This form of asexual reproduction enables them to colonize new areas, expand their population, and adapt to changing environmental conditions. Therefore the correct option is D
