Answer:
Anther contain saclike structure called microsporangia that have micrspores mother cells that develop in to male gametophyte
Explanation:
Sporangia cosist of microspores mother cells and megaspores mother cells in land plant that develops in to male and female gametophyte respectivelly. Then latter on the male gametophyte gie rise to male gametes and female gmetophyte give rise to female gametes and after fusion of the gametes an other gametophyte is arise which give rise to sporophyte and thr sporophyte give rise to gametophtye which is called alternation of generation.
This is a case of carpal tunnel syndrome of the left hand wherein the patient underwent release of the flexor retinaculum or the carpal ligament relieving the pressure on the median nerve. Neurolysis was done to block some fibers of the median nerve to alleviate the pain. The CPT code reported is CPT 64721 which is under n<span>europlasty and/or transposition; median nerve at carpal tunnel.</span>
The endocrine
system is the system that comprises all the glands in the body, from the hypothalamus
pituitary, pineal, thymus, thyroid, parathyroid, adrenal glands, testes and
ovaries. These organ glands mentioned are just the few major glands in the
body. Moreover, take note of the hypothalamus which is responsible for many
functions such as hunger, thirst and other simple urges, that also regulates
the pituitary gland. How does your endocrine conserve body water? By
controlling and regulating your water intake and outtake, ensuring the amount
of electrolytes is efficient. Your hypothalamus is responsible for water
balance hence, it participates in one of the many functions such as regulating
the sweat glands excretion of sweat which is by the process of osmosis promoting
skin-temperature homeostasis.
Answer:
there is a good chance the population of mice will die off or the mice will migrate to a new area.
Explanation:
with there being so many mice and limited food mice will beging to die from starvation. mice might also migrated to a new area to find new food. this could cause competition for food in that new area too.
1) I believe the answer is C. Weddell and Crab eater seal usually form breeding groups or colonies when breeding. The Leopard and Ross seals are solitary when breeding. Antarctic and elephant seals on the other hand breed in dense groups on beaches when breeding.
2) I think the C. Sea ice is frozen water that forms, grows and melts in the ocean.It occurs both in the arctic and antarctic. The sea ice grows during the winter months and melts during the summer months making it a seasonal ice. Areas with sea ice do not absorb much light because sunlight that strike it are reflected back into space.
3) The answer is C. Heat capacity. When the sun heats the surface evaporation of water occurs. The water vapor is lifted into the atmosphere using heat currents. The water vapor combines with dust particles to form clouds which later rain.
4) I think the answer is C. The cold water is denser and thus is moves to the bottom(downwelling). Water that is rich in nutrients then moves up to the surface to replace the cold water. The increased nutrients trigger the growth of organisms like the algae.
5) What is the difference between El nino and La nina. I believe El Nino is the warm phase of ENSO while La Nina is the cold phase of ENSO. El Nino usually brings rainfall and warmth to western pacific regions and coldness and dryness to the eastern pacific region while La Nina brings coldness in the eastern pacific regions and heavy rains that cause floods in the western pacific.
6) The answer is C. During the La Nina year the sea surface temperature is greater than normal in the Western pacific. The La Nina is an exaggeration of the usual seasonal cool cycle unlike El Nino which is an exaggeration of the warm cycle. The La Nina year occurs after some El Nino years.
7) Names for hurricane are beneficial over latitude longitude identification because they are easier to remember. They avoid confusion which is more likely when using latitude longitude identification.They also help to spread awareness and are much easier to track.
8)The answer is B. The leopard is the second largest seal that have powerful jaws and long teeth. They use these teeth to kill smaller seals, fish and squid. They also feed on penguins. This is why they do not rely on krill as a major food source.
9) I believe the answer is A. The Adelie penguins feed mostly on krill but switch to fish during breeding because fish and squid are more abundant and krill is more scarce. I think this is because during the breeding season birds spend short periods at sea and hence more fish is available.
10) The answer is A. Due to the fact that penguins live in cold environments, they have adopted a few features to keep them warm. These features include fat under their skin,layers of features and staying together in groups. Penguins swim fast in order to launch themselves in the air.
11) The population of penguins have greatly increased due to the hunting of baleen whales. Baleen whales are know to eat krill and fishes. This means when there is a reduction of the baleen whales there will be an increase in the amount of krill and fish. This will result to an increase in the amount of penguins since food availability will increase increasing their chances of survival.
