Plantae organism that can make its own food and is composed of many cells that each contain a nucleus belongs to which kingdom.
What is Plantae?Apart than some of the earliest cousins of algae, the class Plantae comprises multicellular creatures. They are eukaryotes, which means they have membrane-bound cellular organelles and a nucleus. Around the cell, there is a cellulose-containing cell wall.
Typically, a mature plant has a single, big central vacuole that is bound by a tonoplast (membrane). The reserve food for plants is starch and lipids (oil/fat).
All plants have cells, which contain plastids, double membrane-covered cell organelles. Photosynthetic pigments are present in several plastids (chlorophylls).
Therefore, Plantae organism that can make its own food and is composed of many cells that each contain a nucleus belongs to which kingdom.

Discuss the orogenies that produced the Appalachian Mountain Range. Include in your answer the timing, process, and resultant sedimentation patterns. Include additional Paleozoic orogenic events to strengthen your answer if need be.
Answer:
Explanation:
Appalachian orogenic belt, an old mountain range that extends for more than 3,000 km (1,860 miles) along the eastern margin of North America from Alabama in the southern United States to Newfoundland, Canada, in the north. The geosynclinal theory of mountain building was first worked out in the Appalachians by James Dana and James Hall in the late 19th century; today a plate tectonic theory is invoked. The earliest Appalachian sediments were deposited near the start of the Cambrian Period (542 million years ago) on the shores of the opening Iapetus Ocean. Subduction of the Iapetus led to its destruction and the collision of different continental blocks and island arcs. Those collisions gave rise to three Appalachian orogenies: the Taconic in the Middle Ordovician (about 472 million years ago); the Acadian in the Middle to Late Devonian (at 390 million to 370 million years); and the Alleghenian in the Late Carboniferous to Permian (300 million to 250 million years ago). The age of these orogenies decreases eastward across the orogenic belt, demonstrating that it was formed by the progressive eastward addition of arcs and continental fragments to the continental margin of North America. The Appalachian belt continues to the east in the form of the Caledonian and Hercynian orogenic belts in western Europe. The Alleghenian orogeny led to the formation of the Pangaea supercontinent during the Permian Period (299 million to 251 million years ago). Geophysical seismic studies show that the southern Appalachian Mountains comprising the Ridge and Valley region, the Blue Ridge Mountains, and the Piedmont region belong to a crustal slab some 6–15 km (3.7 to 9.3 miles) thick that has been thrust 260 km (162 miles) westwards over the former continental margin.

Why does the control of blood sugar by insulin show negative feedback?
Select one:
The release of insulin causes sugar levels to increase even more.
Sugar lowers the levels of insulin back to the normal levels.
The release of insulin brings the sugar levels back to normal.
Insulin mixes with the sugar to prevent it from damaging the cells.
Answer:
The control of blood sugar (glucose) by insulin is a good example of a negative feedback mechanism. When blood sugar rises, receptors in the body sense a change. In turn, the control center (pancreas) secretes insulin into the blood effectively lowering blood sugar levels.

Which two characteristics describe the most stable ecosystem on Earth?
a. They are near the poles
b they are near the equator.
c. They have high biodiversity
d they have few seed plants
Answer:
They have high biodiversity
High at the equator
Explanation:
This is because a stable ecosystem is the one that occur at equilibrium and have the ability to resist any form of resilience or disturbance and still grow fast. A stable ecosystem have high biodiversity because that are comprises of different plants and animals that are able to live and survive. Species diversity are more at the equator than at than at the poles.

The table shows data about abiotic factors of streams in two different watersheds.
In general, a stream with a lower temperature and more neutral pH tends to be healthier. Based on these
criteria, which watershed contains the healthier stream?
Select one:
Watershed 2
Both streams are equally healthy.
There is not enough data provided to answer the question.
Watershed 1
Answer: b
Explanation:
Based on these criteria, the watershed that contains the healthier stream is, that both streams are equally healthy. The correct option is B.
What are abiotic factors?An abiotic factor is a non-living component of an ecosystem that influences its surroundings. Temperature, light, and water are all components of the terrestrial environment.
Abiotic elements in a marine ecosystem include salinity and ocean currents. Abiotic and biotic forces interact to form a distinct ecosystem. Abiotic influences are found in all non-living components of an ecosystem.
They are often made up of both physical and chemical components. Abiotic factors are nonliving components of an ecosystem that influence the environment. Temperature, light, and water are among the examples. Abiotic elements in a marine ecosystem include salinity and ocean currents.

explain how the hydrosphere and atmosphere are related.
Answer:
Water circulates in a cycle across the hydrosphere. Clouds gather water, which then falls to Earth as rain or snow. Rivers, lakes, and seas store this water. Then it evaporates back into the atmosphere, restarting the loop.
Explanation:
Answer:
The hydrosphere is the part of Earth were all the water is contained.
The atmosphere is the part of Earth were all the gases are contained.
These two are related because the hydrosphere is inside the atmosphere.
The hydrosphere goes down below sea level, because of several trenches and other holes like the Mariana trench. The hydrosphere also goes around 20 kilometres in the air because of clouds.

Answer:
Genetic contamination, competition with natural species, creating potential for problematic pathogens, unwanted side effects and unfavorable level of diversity.
Explanation:
The possible risks and drawbacks of the use of genetic engineering are genetic contamination, competition with natural species, creating potential for problematic pathogens, unwanted side effects and unfavorable level of diversity. These drawbacks puts pressure on the native species and due to competition with natural species, removal of natural species occurs. There are many side effects of genetic engineering species on the health and ecosystem.

Which correctly describes a difference between the male and female
reproductive systems?
O A. Males store gametes in the ovary.
B. Females produce fewer gametes.
C. Females produce gametes every day.
D. Males receive gametes from females.
Answer:
B . Females produce fewer gametes.
Explanation:
The option that correctly describes a difference between the male and female reproductive systems is B. Females produce fewer gametes.
What is a reproductive system?The reproductive system is a collection of organs and tissues that work together to produce, transport, and fertilize gametes (sperm in males and eggs in females) to facilitate reproduction. In males, the reproductive system includes the testes, epididymis, vas deferens, seminal vesicles, prostate gland, and urethra.
Sperm are produced in the testes, mature and are stored in the epididymis, and then transported through the vas deferens and mixed with seminal fluid produced by the seminal vesicles and prostate gland before being ejaculated through the urethra during sexual intercourse. In females, the reproductive system includes the ovaries, fallopian tubes, uterus, cervix, and vagina.
Eggs are produced in the ovaries and are transported through the fallopian tubes, where fertilization can occur. The fertilized egg then implants in the uterus, where it can develop into a fetus. Hormones, such as estrogen and testosterone, play important roles in regulating the reproductive system and maintaining sexual characteristics.
