The trait that helps a living organism to survive in its particular habitat or ecosystem is a feature that is most likely to be passed on to subsequent generations.
What is natural selection?Natural selection can be defined as a biological process in which living organisms (individuals) possess certain inherited traits, qualities, and characteristics that enables them in their particular habitat or ecosystem, to successfully adapt to certain environmental factors, survive, and reproduce, as well as passing these traits and genes to their offspring or subsequent generation.
This ultimately implies that, a trait that helps a living organism to survive in its particular habitat or ecosystem is a feature that is most likely to be passed on from generation to generation.

Which of the following is least necessary for plate tectonics?
O A solid core inside the planet
O A semi-solid mantle
Convection currents in the mantle
O A crust divided into plates
Answer:
Convection currents in the mantle
Explanation:
Convection in the mantle is the same as convection in a pot of water on a stove. Convection currents within Earth's mantle form as material near the core heats up. As the core heats the bottom layer of mantle material, particles move more rapidly, decreasing its density and causing it to rise.
Effects
Convection also plays a role in the movement of deep ocean waters and contributes to oceanic currents. Inside Earth, the convection of mantle material is thought to cause the movement of the overriding crustal plates, resulting in events such as earthquakes and volcanic eruptions.
Speed
Estimates of the speed with which Earth's mantle moves range from 1 to 20 cm/year with an average of about 5 cm/year in the case of plate motions to as much as 50 cm/year in hotspots such as the Hawaiian Islands (see Plates, Plumes, And Paradigms (2005) edited by Gillian R.
Direction
Convection currents observed in water rise to the surface and then spread out in both direction. Convection currents in the mantle are thought to operate in the same matter as convection currents in water. ... This shows that the convections currents move outward both right and left after the current reaches the surface.
Heat source
The primary sources of thermal energy for mantle convection are three: (1) internal heating due to the decay of the radioactive isotopes of uranium, thorium, and potassium; (2) the long-term secular cooling of the earth; and (3) heat from the core.
Answer:
A solid core inside the planet.

True or False: In plants, xylem cells, root hair cells, and phloem cells are unspecialized cells.
Answer:
true
Explanation:
In plants, xylem cells, root hair cells, and phloem cells are unspecialized cells. The statement is true.
what are roles of xylem and phloem ?Plants have different tissues to transport water, nutrients and minerals. Xylem involve in the transportation of water and mineral salts from the roots up to different parts of the plant, where as phloem transports sucrose and amino acids.
Xylem is composed of elongated dead cells, continuous vessels (tubes), xylem vessel contain no cytoplasm, impermeable to water, contain woody material called lignin.
Phloem composed of living cells, cytoplasm, transports sucrose and amino acids up and down the plant by a process called translocation.

Answer:
1.875 grams
Explanation:
formula :
N (t) = N0 * (1/2) ^ t/t 1/2
remaining amt = initial amt * (1/2) ^ time/ half life
remaining amt = 60 * (1/2) ^ 53.8/10.76
remaining amt = 60 * (1/2) ^ 5
remaining amt = 1.875
A large number of dopamine-releasing neurons are found in the __________. A. Brainstem B. Hindbrain C. Midbrain D. Forebrain Please select the best answer from the choices provided A B C D.
The substantia nigra (SN) and ventral tegmental region have the most midbrain dopaminergic neurons (VTA). Therefore, option (C) is correct.
Where is dopamine most active in the brain?Dopamine (DA) neurons in the middle brain are absolutely necessary for the control of fundamental aspects of the brain, including the processing of rewards, voluntary movement, and working memory. The substantia nigra (SN) and the ventral tegmental region have the biggest populations of dopaminergic neurons in the midbrain. These two nuclei are located in close proximity to one another (VTA).
As a component of the brain's reward system, dopamine is most prominently responsible for assisting humans in experiencing pleasure. Dopamine can be released in response to a number of different stimuli, including sexual activity, retail therapy, or even the aroma of freshly baked cookies.

What does semi-conservative mean in relation to DNA replication?
Answer:
DNA replication of this kind is referred to as being semi-conservative because the original double-stranded molecule has complementary base pairs of nucleotides, and complementary nucleotides used unzipped single-stranded areas as templates. So, this means that no DNA molecule is completely new because half of the pre-existing DNA molecules are always conserved.
Explanation:
Answer:
relating to or being genetic replication in which a double-stranded molecule of nucleic acid separates
