If an organism's body cells have 12 chromosomes, how many chromosomes will sex cells have? Explain.
Answer:
6 chromosomes
Explanation:
Answer:
The gametes or sex cells produced by the organism will have 6 chromosomes if the organism has 12 chromosomes.
Explanation:
The diploid organism has all chromosomes in pairs, one chromosome inherited from male parent & another chromosome in the pair is inherited from the female parent. If an organism has 12 chromosomes, it has 6 different types of chromosomes, differing from one another in length, the position of centromeres and genes present on these. Six different types of chromosomes constitute a haploid set of chromosomes. Two chromosomes of the same type are called homologous chromosomes and these constitute a homologous pair. The cells producing sex cells or gametes undergo meiosis (reduction division) so that each gamete contains only one chromosome of a homologous pair. The gametes are haploid, having half the number of cells as compared to somatic cells.

which of the following is most likely to occur when a barrier develops between two populations of the same species?
1. gene flow between the groups will increase due to more diversity between them
2. the species will become more distinct from each other
3. both groups will go extinct because there are not enough individuals to support them
4. individuals will develop adaptations that allow them to rejoin the other population
Answer:
The answer is 2
Explanation:
If the populations are separated from each other, they will start to be more diverse.
Drag each tile to the correct location.
Identify each process as a carbon source or a carbon sink.
Carbon sources are any natural or artificial production site of carbon and/or any chemical compounds composed of carbon, such as carbon dioxide and methane.
Carbon source: Combustion,Respiration.
A carbon sink absorbs carbon dioxide from the atmosphere.
Carbon sink: Photosyntheis,Ocean absorption,Fossilization.
Which one is carbon sink or carbon source?1. Photosyntheis: Forests are typically carbon sinks, places that absorb more carbon than they release. They continually take carbon out of the atmosphere through the process of photosynthesis.
2. Ocean absorption: Phytoplankton are the main reason the ocean is one of the biggest carbon sinks. These microscopic marine algae and bacteria play a impotant role in carbon cycle - absorbing carbon.
3. Fossilization: Absorb CO2.
4. Combustion: Combustion is a chemical process in which a substance reacts rapidly with oxygen and gives off heat and CO2 in environment.
5. Respiration: The respiratory system, with its conduction and respiratory zones, brings air from the environment to the lungs and facilitates gas exchange both in the lungs and within the cells and gives out CO2 in atmosphere.
Thus, we can conclude that
carbon sink: Photosyntheis,Ocean absorption,Fossilization.
carbon source:Combustion,Respiration.

A scientist helps a colleague do a better experiment by:
O A. laughing when a common and avoidable mistake is repeated.
B. offering advice about how best to perform a standard procedure.
C. explaining why a hypothesis does not need to be tested in an
experiment.
D. refusing to allow anyone else to use an expensive instrument.
Answer:
B. Offering advice about how best to perform a standard procedure.
Explanation:
Helping others can be in different ways, be it helping out or by giving encouraging words or advice. But in all aspects of help, there is always a positive outcome if help is given in the right way and at the right time. And it is also how one person lifts another.
A scientist can help a colleague out by offering advice and telling the person how to best perform a standard procedure. This will help the colleague do better in the experiment and also help ensure that the right things are done and the efforts are successful. The other options are all negative in their 'approach' which will only hinder the colleague in his/her works.
Thus, the correct answer is option B.
Answer:Offering advice about how best to perform a standard procedure.

Carbon is an organic element found in all life forms. Which of the following occurs through the process of
breaking down carbon-based molecules?
A. Water molecules are transferred through the body.
B. Elimination of waste products occurs.
C. Energy needed for life functions is released.
D. Absorbing of oxygen through pores occurs.
Answer:
C is the Answer.
Explanation:
Carbon is an organic element which when broken down will release energy within an organism.
Process of elimination
A: Wrong because Water has nothing to do with carbon being broken down.
B: Wrong because when carbon is broken down no waste products are being eliminated.
C: Right because Energy is released when Carbon is broken down
D: Wrong because Carbon being broken down has nothing to do with oxygen being absorbed.

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.
