Explanation:
the difference between taxis and tropism is that taxis refer to the directional movement of animals in response to a stimulus while tropism refers to the directional movement of plants in response to a stimulus. ... On the other hand, tropism is the response of plants to a stimulus or to move away from it.

What is the difference between the euphotic zone and the bathyal zone of the ocean
Answer:
Euphotic zone is the layer closer to the surface that receives enough light for photosynthesis to occur. Beneath lies the disphotic zone, which is illuminated but so poorly that rates of respiration exceed those of photosynthesis.
Bathyal zone is the part of the pelagic zone that extends from a depth of 1000 to 4000 metres below the ocean surface. It lies between the mesopelagic above, and the abyssopelagic below.It is ala known as midnight zone.
Explanation:
Describe the natural process that creates a human clone.
Answer: Natural cloning also occurs in animal organisms during processes such as budding (offspring grows out of the body of the parent), fragmentation (the body of the parent breaks into distinct pieces, each of which can produce an offspring), and parthenogenesis. In humans and other mammals, the formation of identical twins is a type of natural cloning.

What does evaporation change from ? Solid ———> liquid Liquid ———-> Solid What does condensation change from Liquid——-> solid Solid———> liquid
Answer:
Evaporation : Liquid --- Gas (Vapor) ; Condensation : Gas (Vapor) --- Liquid
Explanation:
Evaporation is the change of a liquid into gas or vapor, usually by increase in temperature. Eg : Water evaporation into vapors during water cycle, due to sun heat.
Condensation is the change of gas or vapor into liquid, usually by decrease in temperature. Eg : Vapors condensation into water droplets during water cycle, due to lower atmospheric temperature at higher height.

Analyze the diagram below:
According to the model represented in the diagram, which of the following would cause the cell to not express the lacZ, lacY, and lacA sequences?
Binding the RNA polymerase to the gene
Preventing the repressor from binding to the lac operon
Removing the inducer
Transcribing the lacl sequence
Answer:
Transcribing the lacl sequence
Explanation:
lacZ, lacY, and lacA sequences are the structural genes, which needs to be expressed in order to produce their proteinous enzymes required for the breaking down of lactose sugar. The transcription of these three genes must occur with the aid of RNA polymerase binding to them.
However, a gene sequence called lacI encodes information for an repressor, which when expressed can inhibit the expression of the genes lacZ, lacY, and lacA. Hence, the TRANSCRIPTION OF THE LACL SEQUENCE cause the cell to not express the lacZ, lacY, and lacA sequences.
Answer: removing the inducer
Explanation: all sequences need an inducer present in order for them to be expressed

Explain what the title of this article and video, "The Albatross, Harbinger of Human Migrations" means. In what ways should humans and their governments act like the scientists working with albatrosses
Answer:
Albatross are the indicators for migration of humans.
Explanation:
The Albatross, Harbinger of Human Migrations" means that Albatross are the indicators for migration of humans from that location. Humans and their governments act like the scientists working with albatrosses by making environment suitable for them. The humans have to reduce interventions in the places where they are present in order to increase occur in their population. governments should made policy for them to secure their habitat and prevent them from extension.

What is the difference between extrusive and intrusive igneous rock?
Intrusive igneous rock forms below ground and extrusive igneous rock forms above ground.
Intrusive igneous rock forms above ground and extrusive igneous rock forms below ground.
Intrusive igneous rocks form when sediments are compacted together and extrusive igneous rocks form when sediments separate.
There is no difference, they both form above ground.
Answer: I'm pretty sure it's the first one
Explanation: I don't know for sure but I'm pretty sure when I learned it they said that extrusive is above ground and intrusive is below ground. Don't take my word for 100% though

What type of molecule forms the antibodies found in the human immune system?
Answer:
An antibody
Explanation:
up to about three thousand million years ago there was no oxygen in Earth's atmosphere today about one-fifth of the atmosphere is oxygen gas. suggest what caused this change???
pls help
Answer:
Oxygen makes up about one-fifth the volume of Earth's atmosphere today, and is a central element of life as we know it.
But that wasn't always the case. Oxygen, although always present in compounds in Earth's interior, atmosphere, and oceans, did not begin to accumulate in the atmosphere as oxygen gas (O2) until well into the planet's history. What the atmosphere was like prior to oxygen's rise is a puzzle that Earth scientists have only begun to piece together.
Earth coalesced a little more than 4.5 billion years ago from bits of cosmic debris. Liquid oceans existed on the planet almost from the beginning, although in all likelihood they were repeatedly vaporized by the massive meteorites that regularly clobbered the planet during its first 700 million years of existence. Things had settled down by 3.8 billion years ago, when the first rocks that formed under water appear in the geologic record. (They exist in what is now southwest Greenland.)
If Earth had water, it must have had an atmosphere, and if it had an atmosphere, it must have had a climate. What was Earth's early atmosphere made of? Nitrogen (N2), certainly. Nitrogen makes up the bulk of today's atmosphere and likely has been around since the beginning. Water vapor (H2O), probably from volcanic emissions. Carbon dioxide (CO2), also emitted by volcanic eruptions, which were plentiful at that time. And methane (CH4), generated inside the Earth and possibly also by methane-producing microbes that thrived on and in the seafloor, as they do today.
Carbon dioxide, water vapor, and methane played an important role in Earth's subsequent development. Four billion years ago, the Sun was 30 percent dimmer, and therefore colder, than it is today. Under such conditions, Earth's water should have been frozen, yet clearly it wasn't. The water vapor, carbon dioxide, and methane acted as greenhouse gases, trapping heat and insulating the early Earth during a critical period in its development.
Of oxygen, meanwhile, the early atmosphere held barely a trace. What did exist likely formed when solar radiation split airborne molecules of water (H2O) into hydrogen (H2) and oxygen (O2). Hydrogen, a lightweight gas, would have risen above the atmosphere and slowly been lost to space. The heavier oxygen gas, left behind, would have quickly reacted with atmospheric gases such as methane or with minerals on Earth's surface and been drawn out of the atmosphere and back into the crust and mantle. Oxygen could only begin to accumulate in the atmosphere if it was being produced faster than it was being removed'—in other words, if something else was also producing it.
That something was life. Although the fossil evidence is sketchy, methane-producing microbes may have inhabited Earth as long ago as 3.8 billion years. By 2.7 billion years ago, a new kind of life had established itself: photosynthetic microbes called cyanobacteria, which were capable of using the Sun's energy to convert carbon dioxide and water into food with oxygen gas as a waste product. They lived in shallow seas, protected from full exposure to the Sun's harmful radiation. (To learn more about these organisms and the fossil evidence for them, watch the accompanying video "Early Fossil Life.")

Answer:
1. 0 chance (0%)
2. 2 chances (50%)
3. 4 chances (100%)
Explanation:
the way a punnet square works is that you basically multiply two genes. for example:
b b
B Bb Bb
b bb bb
then, if it's uppercase, it is dominant. if it's dominant, it will take over the recessive gene. if it was Bo, B being brown and dominant, and o being recessive and orange, then brown would take over. there are also cases with codominant but that's not in the question. feel free to ask me anything about this.
how would you describe the motion of a transverse wave

If a DNA strand has 32 % guanine, what percent thymine does it contain?
A) 36%
B)18%
C)64%
D)32%
Answer:
B
Explanation:
Guanine and Cytosine pair together. So, if 32 percent is guanine, then 32 percent should also be cytosine. This is a total of 64 percent. The remaining 36 percent is split between thymine and adenine. So, Thymine will have half of 36 percent which is 18 percent.
