Answer:
Four differences between excretion in flowering plants and excretion in human are as follows.
(1) In a plant, oxygen is a by-product of excretion whereas, in animals, urea is produced.
(2) Plants do not have exclusive excretory organs while humans do have them.
(3) Plants tend to shed their parts while excreting while humans do not tend to shed their organs for the process.
(4) Some solid waste products of plants are stored in their dead cells whereas, in humans, all excretion product gets passed out of the body.

what does it mean when an emission line of helium from a galaxy is shifted toward red
A. The galaxy contains a small percent of Hydrogen
B. The Galaxy is moving toward the viewer
C. The galaxy is moving away from the viewer
D. The galaxy contains a large percent of hydrogen
Answer:
the answer is the galaxy is moving away from the viewer! lemme know if you need the rest of the answers or anymore help
Explanation:
i took the test :)
When an emission line of helium from a galaxy is shifted toward red, it means that the galaxy is moving away from the viewer. Thus, the correct option is C.
What is Galaxy?The Galaxy may be defined as a tremendous collection of dust, gas, dark matter, and billions of stars and their solar systems, all held together by gravity.
When it is shifted toward red, it describes the displacement of an emission line of helium from a galaxy to longer wavelengths. This alteration is interpreted as a doppler shift.
It depends on the location of any celestial body in a galaxy. The farther from us a star is, the more its light has shifted towards the red end of the visible spectrum.
Therefore, when an emission line of helium from a galaxy is shifted toward red, it means that the galaxy is moving away from the viewer. Thus, the correct option is C.

Moosehead Lake in Maine is a beautiful lake, spanning 74,890 acres with a maximum depth of 246 feet. The most sought-after fish to be found in Moosehead Lake are: Landlocked salmon, lake trout, brook trout, and burbot. According to Tim Obrey, a regional fisheries biologist with the Maine Department of Inland Fisheries and Wildlife, the fishing at Moosehead declined from phenomenal to just "really good" during the late 1980s, but has rebounded due to careful management. This table shows the populations of three major fish in Moosehead Lake over a 30 year period. Moosehead Lake was illegally stocked with smallmouth bass in 1970. Fish Populations in Moosehead Lake Year Smallmouth Bass Salmon Lake Trout
Smelts are the primary food source for lake trout and salmon in Moosehead. In the late 1980s, we documented a dramatic increase in the abundance of wild lake trout in Moosehead Lake. Swelling lake trout numbers taxed the forage base and the smelt population took a dive. What would be appropriate action for Wildlife Management to make to correct the problem? Choose ALL that apply.
B) One hundred small, one-hectare size areas should be conserved
C) Native species should be maintained or planted within the greenspace to promote biodiversity.
D) Exotic species should be cultivated and planted to increase biodiversity in the protected greenspace.
E) The majority of the secondary consumers should be removed from the greenspaces to promote an increase in lower levels of the food chain.
(WILL GIVE BRAINLIEST WHOEVER CAN ANSWER RIGHT!!!!!!)
When one of the trophic web links disappears, it affects the whole chain. In management programs it is important to consider these consequences to keep the whole ecosystem equilibrium. In the exposed situation, Native species should be maintained or planted within the greenspace to promote biodiversity and The majority of the secondary consumers should be removed from the greenspaces to promote an increase in lower levels of the food chain.
--------------------------------------
The trophic chain is the energy transference process that involves different organisms, from autotroph or producers, to the consumers or decomposers.
The disappearance of one link affects the whole system. The direct superior link does not have enough food supply, while the immediately anterior link is beneficiated for not being eaten by its predator. And finally, as this last link will overgrow, it will consume greater quantities of its food, causing a decrease in its anterior link. Top-down control refers to scenarios where superior predators control the structure and dynamic of an ecosystem.
It is necessary and significant to consider these modifications in the whole ecosystem while planning management actions to keep an equilibrium.
In the exposed example we know that the most wanted species are
Landlocked salmon, lake trout → which increased its population size sharply over the last yearsbrook trout, and burbotSmelts, which are the primary food source for lake trout and salmon, decreased in population size significantly.
Finally we know that smallmouth bass was introduced in 1970.
This information suggests that the decrease in smelts' population is due to the predation of the species by the lake trout, which population increased sharply in size. The change on smelts' population size, might affect the blook trout and salmon populations, that also feed on semelts, and might also affect other species occupying inferior levels.
When implementing a management program, it would be necessary to promote biodiversity by growing native species in greenspaces and ensure their survival and reproductive succes. In the exposed case, it is necessary to preserve smelts' population, so it would be also necessary to remove from these green spaces the secondary consumers -trouts and salmon- that feed on them, to ensure the smelts' population growth and recovery.

Answer:
The Answer is A, C, and D
Explanation:
Wildlife management reacted to the increase in trout and depletion of smelt by liberalizing bag limits on lake trout and allowing harvest of smaller fish. We also severely reduced the salmon stocking rates. Salmon and trout populations had to be controlled until smelt could rebound.

Lloyd’s lab partner is looking down into a test tube while he heats the contents by using a flame. Which action should Lloyd recommend to his partner if heating must continue?
Wear safety goggles while looking into the opening of the test tube.
Cover the opening of the test tube so that no materials can boil out of it.
Move the test tube so that the opening is pointing away from all students.
Put the test tube in a hot water bath so that no water can enter its opening.
The correct action that Lloyd should recommend to his partner who was looking down into the test tube if heating must continue would be to move the test tube so that the opening is pointing away from all students.
Wearing safety goggles (and looking directly down at the test tube) might not be enough to protect Lloyd's partner nor other students in case the content of the test tube splashes out.Covering the test tube might hinder any generated gas as a result of heating from escaping safely into the air and this might cause an explosion.Putting the test tube in a hot water bath so that water can enter its opening will definitely affect the reaction and prevent them from getting accurate results/observations.Hence, the most correct action would be for Lloyd's partner to move the test tube so that the opening is pointing away from all students.

8. At the surface of a swimming pool a 2.0 L balloon is under 760 mmHg of pressure. If that balloon is taken to the
bottom of the deep end, the pressure is now 950 mmHg. What is the new volume of the balloon?
0.45 L
b. 1.6L
2.4 L
d. 95 L
a.
C.
voru
The new volume of the balloon is 1.6L
HOW TO CALCULATE THE FINAL VOLUME:
Using Boyle's law, which states that the pressure of a given gas is inversely proportional to its volume i.e PV = KBoyle's law equation is as follows:
P1V1= P2V2
Where;
P1 = initial pressure (mmHg)P2 = final pressure (mmHg)V1 = initial volume (L)V2 = final volume (L)According to this question,
P1 = 760mmHg
V1 = 2L
V2 = ?
P2 = 950mmHg
Using P1V1 = P2V2
760 × 2 = 950 × V2
1520 = 950V2
V2 = 1520/950
V2 = 1.6L
Therefore, the new volume of the balloon is 1.6L

Answer:
Explanation:
Need to Know. How are you creating a need to know the content that is recorded? Just because I record something, or use a recorded material, does not mean that my students will want to watch, nor see the relevance in watching it.
Engaging Models. One of the best way to create the "need to know" is to use a pedagogical model that demands this. Whether project-based learning (PBL), game-based learning (GBL), Understanding by Design (UbD), or authentic literacy, find an effective model to institute in your classroom.
Technology. What technology do you have to support the flipped classroom? What technology gaps exist that might hinder it? Since the flipped classroom is about recorded video, then obviously students would need the technology to do this.

Explanation:
How is the Nucleus like a brain?
Answer:
The nucleus contains the DNA of the cell which can be thought of as the brain of the cell.
The nucleus responds to stimuli via receptors which can be primary or secondary. Basically, an external ligand (hormone, protein, nutrient, etc) binds to the surface receptor of a cell, this, in turn, causes the receptor to release a messenger (most of the time circular AMP (cAMP)) which binds to a secondary receptor which is either directly inside the nucleus or on the nuclear envelope. Finally. the portion of the DNA which is responsible for the protein to respond to the ligand is activated and begins transcription.
The activated DNA section (gene) produces mRNA which in turn produces a protein in response to the ligand.
On top of this, the entire cell cycle of rest, growth, and division is controlled by the nucleus.
