The number of chromosomes is DOUBLED after mitosis. True or False, AND explain.
PLEASE HELP IT'S DUE TODAY!!!!
Answer:
False
Explanation:
The number of chromosomes is doubled during mitosis, but each daughter cell (new cell) has the same number as the mother (original cell)
Mitosis is a cell division cycle in which the parent cell divides to produce equivalent daughter cells. It can occur in the body for growth, replacing dead cells etc.
The statement is False.
The sentence can be explained as:
Mitosis is a function of division in cells in which the two exact daughter cells are produced from the parent cell division of the nucleus and cytoplasm.The parent cells undergo the doubling of the hereditary content by the process of central dogma during the synthesis stage. The parent and daughter cell is diploid during this sort of cycle and does not get halved or duplicated at the end of the cycle.Therefore, chromosomes do not get doubled at the end of the division.

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.

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.

experiment supports a hypothesis and
has been repeated?
A. developing a theory
B. redoing the hypothesis
C. graphing the data a different way
D. setting up another experiment based on the same
hypothesis
Answer:
A
Explanation:
The end result of repeated experiments supporting a hypothesis is for the hypothesis to become a theory.
In science, a hypothesis is a general statement that needs to be validated or invalidated by experiments. Once a hypothesis is found to be valid by several independent but similar experiments, such a hypothesis becomes a theory.
Formulation and testing of hypotheses (via experiments) represent two of the key steps in the scientific method.

Answer:
Explanation:
Frogs:
Frog's evolutionary pathway resembles the water cycle. This is quite fitting, because all frogs statistically enjoy bodies of water. Seafrogs absorb salt-water through holes, which emit inside the snout. First, they grow two limbs, or legs, to swim. These turn into fins, which, eventually, allow for hopping and balancing-capacity. Capabilities, include: tongue-roll, sticky toes, bubbly neck, multi-eggs, and more

Answer: The correct statements are 1 and 2:
1.Self-pollination occurs when the pollen from the anther is deposited on the stigma of the same flower, or another flower on the same plant.
2.Cross-pollination is the transfer of pollen from the anther of one flower to the stigma of another flower on a different individual of the same species.
Explanation:
Pollination is the transfer of pollen grains from an anthers to a receptive stigma. In most species of flowering plants, external agents bring about pollination. Also, flowers have evolved special structures and mechanisms to ensure successful pollination.
There are two types of pollination
--> Self pollination: This takes place when mature pollen grains from the anther of a flower fall on the stigma of the same flower or that of another flower on the same plant. This type of pollination brings the male gametes and egg cells of the same plant together. The resultant offspring show very little genetic variation.
--> Cross pollination: This occurs when mature pollen grains of a flower are transferred to the stigma of a flower of another plant of the same or closely related species. This brings the male gametes and egg cells of two different parent plants together. Therefore, there is greater genetic variation among the offspring.

Messenger RNA
Ribozymes
Ribosomal proteins
I only
I and II only
II only
I, II, and III
Answer:
1. and 2. only
Explanation:
rRNA is sometimes called a ribozyme or catalytic RNA.
Molecules of rRNA are synthesized in a specialized region of the cell nucleus called the nucleolus, which appears as a dense area within the nucleus and contains the genes that encode rRNA.
mRNA is Messenger RNA which are synthesized during DNA transcription as templates for the production of a specific proteins.
The molecules are produced during transcription are - Messenger RNA and Ribozymes that is - I and II only.
Transcription is the first step in decoding a cell's genetic information. During transcription, enzymes called RNA polymerases build RNA molecules that are complementary to a portion of one strand of the DNA double helix
the information in a strand of DNA is copied into a new molecule of messenger RNA (mRNA)carried out by an enzyme called RNA polymeraseproduces a number of accessory proteins called transcription factors.Ribozymes are catalytic RNA molecules. They have the intrinsic ability to break and form covalent bonds in RNA moleculesthus, The molecules are produced during transcription are - Messenger RNA and Ribozymes that is - I and II only.
