<span>Insects are found in almost all ecosystems on Earth, with the rarity being oceans. While some species, such as coconut crabs, sand hoppers, woodlice and pill bugs dwell on land, crustaceans are generally found in water — and usually oceanic — regions. Adapting to their habitat, many insect species evolved wings — two pairs for most and one pair for others. A tracheal system is also present for breathing. Crustaceans, on the other hand, breathe using gill-like mechanisms.</span>
In cardiac muscle
a. an action potential spreads throughout the Z discs.
b. intercalated discs connect the muscle fibers together.
c. calcium enters the cell from storage chambers called intercalated discs.
d. potassium is released from the sarcoplasmic reticulum
Answer:
b. intercalated discs connect the muscle fibers together.
Explanation:
Intercalated discs are components of the muscles found in the heart(cardiac muscles).
Intercalated discs join the cardiomyoctes (muscle cells or fibers) together so that they can function as one and transmit signals amongst themselves during the contraction of the heart.
Intercalated discs are made of up desmosomes and gap junctions.
Intercalated discs are found on the lining of the sacromere and can only be seen by using a microscope to observe the longitudinal section of the heart tissue.
Among the listed options, we can conclude that option C which states that "<em>It results in the </em><em>diversity </em><em>of the </em><em>species</em><em> that enhances the probability of </em><em>survival</em><em>.</em>" is correct.
Sexual reproduction offers organisms an advantage over those who undergo Asexual reproduction. Though there are benefits and drawbacks to each method, Sexual reproduction is a method that is <u>better adapted to a changing environment and promotes the faster </u><u>evolution </u><u>of a </u><u>species</u><u>.</u>
The main benefit of sexual reproduction is that it allows for a<u> </u><u>greater diversity </u><u>of the </u><u>species</u><u> which enhances the probability of </u><u>survival</u><u>.</u> This is due to the fact that sexual reproduction leads to varying combinations of alleles for specific traits, which coupled with selective reproduction (<em>the ability of a member of the species to choose a spouse with desirable traits</em>) <u>leads to </u><u>offspring </u><u>who over time are increasingly better </u><u>adapted </u><u>to life in the given </u><u>environment</u><u>, with specific traits tailored for </u><u>survival</u><u>.</u>

Wrong carbon dioxide goes into the plants leaves and comes out as fresh air
Answer: D.
The E. reticulum and Golgi bodies are concerned with secretion and synthesis of molecular substances e.g protein , lipids and steroid. Therefore these cellular organelles should contain Plasma B cells and Islets of Langerhans. for protein hormone synthesis(insulin) and antibodies production
Explanation:
