Answer:
ribosomes
Explanation:
how many organelles are there in a cell. What are their names and what do they do. I am keeping notes
Answer:
Nucleus - controls all activities of the cell
Nucleolus (in the middle of the nucleus)
- the synthesis of ribosomes and RNA (ribonucleic acid)
Mitochondria (battery of cell) - oxidise glucose to release energy in the form of ATP ( adenosine triphosphate)
Edoplasmic reticulum
1. Smooth - synthesises lipids
2. Rough- Transport proteins synthesised by ribosomes
Golgi apparatus ( golgi body, or any golgi, is has many names)
- Acts as Centre for processing, packaging and transporting macromolecules such as proteins and carbohydratez
Ribosomes - sites of protein synthesis
Lysosomes- Break down macromolecules such as proteins, lipids etc
Vacuoles - store food substances, site for waste products
Centrioles - form spindle fibres during cell division
Cytoplasm ( the so call empty spaces in the cell)
- place where biochemical reactions occur
Plasma membrane
-control movement of substances in and out of the cell due to its semi permeable characteristics
Ok that's all for animal cells, but for plants cells, there is more
Cloroplast - site for photosynthesis
Cell wall - Maintains the shape of plant call, give support to cells

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

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.

a essay explaining why i choose a certain university
Answer:
Because the facilities here for my subject are second to none” – this shows that your subject has been at the forefront of your mind when making a sensible choice of university, again demonstrating your level of commitment to it. You can mention specific facilities to show that you’ve read into it thoroughly.
“Because I liked the approach this university takes to my course” – even within the same subject, every university takes a slightly different approach to the way it’s taught and structured. The university question is another good opportunity to show that you’ve really thought about the course and gone to the effort of finding a university whose approach to the subject you agree with. You can even name specific modules that set this university’s course apart from the others offering the same subject.
Along similar lines, you could also mention the university’s great reputation for your subject, or the presence of certain lecturers you feel inspired by (though don’t let this last point dominate your answer; lecturers often move about or go on sabbatical, so even if there’s a particular academic you admire, they may not end up teaching you).

How do moon jellies obtain energy?
Answer:
Like all true jellies, the moon jelly's tentacles are covered with specialized stinging cells, called cnidocytes. ... They have very little nutritional value, however, so the predators that specialize on them must eat hundreds and hundreds of these jellies in order to maintain their required energy levels. Moon jellies stay close to shore, and they pulse their bell to keep themselves near the surface, with their tentacles pointed down. This ensures they can gather as much food as possible. They gather food when it gets stuck in the mucus along the bottom of the bell.
Hope this helps <3 PMB (plz mark brainliest)
Answer:
While it might be nice to grow the missing part back, doing so takes a lot of energy that simply may not be available. For the moon jelly, it takes less energy to simply rearrange the parts in its gelatinous body into a new symmetrical and hydrodynamically efficient configuration and keep moving along on its journey.

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.

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.

What is DNA fingerprinting?The technique of identifying a person's DNA traits is called DNA profiling. DNA barcoding is a type of DNA analysis used to identify species rather than specific individuals. The nucleotide sequences of specific areas of human DNA that are particular to each person are utilized in the laboratory procedure known as DNA fingerprinting to ascertain a person's likely identification.
DNA fingerprinting is a method for detecting and analysing individual DNA variations. It is based on polymorphism and variability in DNA sequences. Applications of it include: It is utilized in forensic science to pinpoint potential criminal offenders. to establish family relationships and establish paternity.

why do translocation sometimes reduces the total number of chromosomes
Answer:
When two nonhomologous chromosomes mutate by exchanging parts, the resulting chromosomal rearrangements are translocations. Here we consider reciprocal translocations, the most common type. A segment from one chromosome is exchanged with a segment from another nonhomologous one, so two translocation chromosomes are generated simultaneously.
