As TSH levels fall, the thyroid gland slows down thyroxin secretion.
True or False
Answer:
I think s its True
Explanation:
What do low levels mean? Low TSH levels indicate hyperthyroidism. This is also known as an overactive thyroid. If the thyroid gland is secreting levels of hormones that are too high, the pituitary gland produces less TSH

Which plate is located furthest SOUTH?
Answer:
Antarctic plate
Explanation: The Antarctic Plate started to subduct beneath South America 14 million years ago in the Miocene epoch. At first it subducted only in the southernmost tip of Patagonia, meaning that the Chile Triple Junction lay near the Strait of Magellan.

what occurs if a cell is damaged beyond repair?
Answer:
Apoptosis
Explanation:
Answer:
Apoptosis is programmed cell death, and it usually occurs when the DNA of the cell is damaged beyond repair. Photosynthesis and glycolysis are normal metabolic processes of the cell, and would not result from irreversible damage.

1. Name the protists fitting each of the following descriptions.
Write down only the correct name next to the relevant question number.
1.1 A protozoan which moves using its pseudopodia.
1.2 A protozoan which moves using its flagellum.
1.3 A filamentous green alga.
1.4 A unicellular green alga.
1.5 Microscopic protists which appear as symmetrical, human-made, and
glass-like ornaments.
1.6 Protists that look like fungi.
(6)
Answer:
1.1 Amoeba
1.2 Paramecium
1.3 Citations
1.4 Single algae cells
A protozoa that moves using its pseudopodia is an amoeba, one using its flagellum is Euglena and a filamentous green alga is Spirogyra. Chlamydomonas is a unicellular green alga. Microscopic protists that are symmetrical, man-made and appear as glass-like ornaments are diatoms while a protist that looks like a fungus is a mold.
What are Protists?A protist is a type of eukaryotic organism which is not an animal, plant, or fungus sharing a common ancestor. These are to the exclusion of other eukaryotes which means protists do not form a natural group or clade.
Protists are a group of diverse eukaryotic mainly unicellular microscopic organisms which share certain morphological and physiological characteristics with animals or plants or both.
Several protists showing different functions like an amoeba pushes out its cell membranes to form pseudopods. Euglena belongs to the class of protozoans known as flagellates. Spirogyra has a slender bright green color with a spiral shaped pigment that holds chlorophyll. Chlamydomonas is found in ponds, ditches and moist soil. Diatoms have a silky jewel-like covering. A mold is a protist which is a fungus.
Thus, a protozoa that moves using its pseudopodia is an amoeba, one using its flagellum is Euglena and a filamentous green alga is Spirogyra. Chlamydomonas is a unicellular green alga. Microscopic protists that are symmetrical, man-made and appear as glass-like ornaments are diatoms while a protist that looks like a fungus is a mold.

Only one plane divides the bodies of humans, dogs, and rabbits into roughly symmetrical "left" and "right" halves.
What type of symmetry do these organisms have?
A.
orbital
B.
bilateral
C.
radial
D.
rotational
Answer: Bilateral
Explanation:
symmetry is a type of symmetry in which only one plane divides an organism into halves that are roughly mirror images of each other. The halves need to be mirror images only on the exterior.
If more than one plane of symmetry exists for an organism's body, then it is radially symmetric.
What are ocean waves caused by? What affects how large they are?
Answer:
Waves are most commonly caused by wind.The size of a wave depends on three factors: the distance over which the wind blows across open water, the strength of the wind, and the duration that the wind blows. The larger these factors, the larger are the waves.

uhm i have 5 questions due in an hour so please help. It's 45 points and they're all abt biology btw~
Answer:
the point of science is to disprove hypothesis so having a hypothesis that doesn't allow that to happen is not good science
2. they don't fit in our mouths so are a trait from when we had larger jaws
3. bones of your lower jaw, middle ear and voice box (they aren't actually gills fyi, they just look like them)
4. likely yes as their bones were hollow but likely only able to fly short distances, the thought was that they couldn't do their size and weight but with hollow bones they were able to like a quail would
5. no because they could be sister taxa, you would have a hard time proving exactly that this new fossil is the common ancestor that birds came from to replace the old hypothesis (guess) of which one did.
Explanation:
Answer:
A: It is wrong to form a theory that cannot be disproven because the whole point of a theory is to test the theory and prove it.
B: Wisdom Teeth are considered to be a vestigial trait because it is passed along in genetics of humans and is a almost a 100% chance of occurrence.
C: This bird could fly because fossils and research has shown that this creature had similar bone structure to a common day bird.
D: This does not invalidate evolution because many geographic events can happen that may alter the positioning of these fossils like: Any type of corrosion or weathering, or maybe ancient civilization have dug up these fossils and then they were reburied.
Explanation:
For C you can look up archaeopteryx and find an article for evidence

Which nitrogenous base would pair with adenine during DNA replication?
A
O cytosine
<
B
O guanine
C
Othymine
D
ouracil
The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.
What are nitrogenous base?
Replication relies on complementary base pairing, that is the principle explained by Chargaff's rules and adenine (A) always bonds with thymine (T) and cytosine (C) always bonds with guanine (G). 18% became cytosine pairs with G. A pairs with T. T and C are not complementary base pairs, but we know that if molecules consists of 32% T, it must have 32%.
The discovery of the structure of DNA was useful because it revealed how mRNA was used to make proteins. There are four nitrogen bases of DNA nucleotides are such as adinine, thymine, guanine and cytosine.
HDL stands for high-density lipoprotein or good cholesterol which absord cholesterol and send it to lever. The lever then flushes it from the body. High-density lipoprotein can lower your risk for heart disease and stroke.
Therefore, The nitrogenous base would pair with adenine during DNA replication is othymine. Thus, option C is correct.

A. What are the two main types of seismic waves that are created during an
earthquake? p waves s waves surface waves
Explanation:
There are two broad classes of seismic waves: body waves and surface waves. Body waves travel within the body of Earth. They include P, or primary, waves and S, or secondary, waves. P waves cause the ground to compress and expand, that is, to move back and forth, in the direction of travel.

What is the name of the gradient between high pressure and low pressure?
Answer:
Pressure gradient
Explanation:
Hope this helps :)
Answer:
Pressure gradient
Explanation:
The change in pressure measured across a given distance is called a "pressure gradient". The pressure gradient results in a net force that is directed from high to low pressure and this force is called the "pressure gradient force". The pressure gradient force is responsible for triggering the initial movement of air
