Answer:
They are modified by shape, function, or size. They are made to have certain roles in different parts of our bodies. These cells group together to make/form tissues. Then these tissues make up organs that we obviously need. Different specialized cells include blood cells, nerve cells, and reproductive cells.

how do you collect maple leaves in animal crossing
Answer:
Explanation:
Similarly to how Cherry Blossom Petals work during the Spring, you can get Maple Leaves by searching for a large orange leaf falling from the sky on your island during this limited period in the Autumn. It's random when and where these leaves will fall on your island, so always be on the look out for one to appear!

mendel’s law of segregation states that the two alleles for each gene separate during gamete formation. during which stage of meiosis do the alleles separate?
The stage of meiosis at which the alleles separate is anaphase. The correct option is B.
What is meiosis?Meiosis is a type of cell division of germ cells that produces gametes such as sperm or egg cells in reproducing organisms through gametes.
It entails two rounds of division, resulting in four cells with only one copy of each chromosome.
Meiosis 1 separates a pair of homologous chromosomes and converts a diploid cell to a haploid cell. It is divided into four stages: prophase, metaphase, anaphase, and telophase.
The homologues are pulled apart and moved to opposite ends of the cell during anaphase I.
The sister chromatids of each chromosome, on the other hand, remain attached to one another and do not separate. Finally, in telophase I, the chromosomes arrive at the cell's opposite poles.
Thus, the correct option is B.

Which type of molecule transfers information from the nucleus to the cytoplasm in the eukaryotic cell
Answer:
The RNA molecule transfers information from the nucleus to the cytoplasm in the eukaryotic cell through transcription and translation.
Explanation:
The type of RNA that contains the information for making a protein is called messenger RNA (mRNA) because it carries the information, or message, from the DNA out of the nucleus into the cytoplasm.

Explanation:
What are MAD (mitotic arrest deficient) proteins and when are they important in the cell cycle?
Answer:
The mitotic arrest deficient protein MAD2B (MAD2L2) is a member of a MAD family of proteins and shows 48% similarity to MAD2 (MAD2L1) [1], [2]. Both MAD2 and MAD2B can bind to the anaphase promoting complex or cyclosome (APC/C), which is a downstream target of the mitotic spindle checkpoint.MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.
The cell cycle ensures the duplication of the genome and its distribution in daughter cells by passing through a coordinated and regulated sequence of events.
A series of checkpoints guarantee the orderly progression of the phases of cell division and the correct distribution of the duplicated genetic material in the daughter cells.
The checkpoints during mitosis are:
At the end of stage G1 and before S.Before anaphase in mitosis.DNA damage checkpoints in G1, S or G2.The checkpoint before anaphase in mitosis guarantees the separation of chromosomes, and operates by activating the Mad2 protein that prevents the degradation of segurin, until the conditions are appropriate.
That is, the Mad2 protein prevents the segregation of sister chromatids until they have all bound to the spindle.
Therefore, we can conclude that MAD (mitotic arrest deficient) are proteins related to spindle cell cycle checkpoint and it is important since they prevent the segregation of sister chromatids until all have bound to the spindle.

If I had a section of DNA that contains 350 nucleotides and the A's and Ts made up 200 of
those nucleotides, how many As
Gs
Cs
and Ts
do I have?(.5 points each response)
Answer:
100 A
100 T
75 C
75 G
Explanation:
there will be an equal amount of thymine and adenine since they bind together so, 200/2 = 100 each
now there is 150 nucleotides left
guanine binds to cytosine so they also have an equal amount, so 150/2=75
Answer:
As = 100
Ts = 100
Gs = 75
Cs = 75

Imagine for a moment that a large artery formed two branches carrying blood to two different organs. Branch 1 has a radius of 0.5 cm and Branch 2 has a radius of 1.0 cm. If the blood flow rate in Branch 1 is 2ml/min, what do you expect the blood flow rate of Branch 2 to be
The flow rate through Branch 2 is 8·√2 ml/min
Reasons:
Radius of Branch 1 = 0.5 cm
Radius of Branch 2 = 1.0 cm
Flow rate, Q = Velocity, V × Area, A
The area of the Branch 1 = π × 0.5² = 0.25·π
We have;
[tex]\dfrac{v_1^2}{r_1} = \dfrac{v_2^2}{r_2}[/tex]
Which gives;
[tex]v_2 = \mathbf{\sqrt{\dfrac{v_1^2}{r_1} \times r_2}}[/tex]
[tex]The \ velocity \ of \ Branch 1 , \ v_1 = \dfrac{2}{\pi \times 0.5^2} = \dfrac{8}{\pi}[/tex]
Therefore;
[tex]v_2 = \sqrt{\dfrac{\left(\dfrac{8}{\pi} \right) ^2}{0.5} \times1} = 8 \cdot\dfrac{\sqrt{2} }{\pi}[/tex]
[tex]The \ flow \ rate, \ Q_2 = 8 \cdot\dfrac{\sqrt{2} }{\pi} \times \pi \times 1^2 = 8 \times \sqrt{2}[/tex]
The flow rate through Branch 2 = 8·√2 ml/min

what type of ions carry the impulse across the synapse from one neuron to the next ?
It's the sodium ion.
When a neural impulse is fired in both neurons, it is always cause by an excited electron in one neuron moving to the other neuron to destabilize the balance of ions trying to keep them at equilibrium. This action either depolarizes or hyper-polarizes the membrane. If it does, then sodium ions--the key deficient ones--can flow into that region of low charge and maintain that state of low charge, keeping the cell membrane stable.
what is true of a fossil that is classified as a transitional form?
Given our understanding of the situation, we can confirm that a fossil classified as a transitional form, will show characteristics both of its ancestors and of the descendants that derived from it.
Transitional fossils are just that, fossilized remains of a transitional phase of evolution. What this means is that as species evolve, there will always be a point in time where a species is at a halfway point in between the species from which it comes, and the species that it will become.
These fossils, due to being a halfway point, will have characteristics that belong to their ancestors, but also characteristics that belong to their descendants, which is only logical considering that evolution is a process that spans many generations, not something instant.
