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.

DNA Synthesis
In preparation for cell division, the cell makes a replica of its entire DNA. This happens during the S, or synthesis, phase of the cell cycle. Mitosis is the division of one cell into two cells that each has a nucleus and the same amount of DNA as the original cell.

Which statement about the specific immune response is FALSE?
Each T or B cell has antigen receptors for only one specific antigen.
T and B cells recognize antigens by using antibodies bound to their surface membranes.
Unique antigen receptors are created by genetic recombination.
Antigens must be presented by an MHC molecule for T and B cells to recognize them.
All cells express MHC-I molecules, but only antigen-presenting cells express MHC-II molecules.

1. how would dr.budai refer to the new fern that contractors plan on introducing into the environment?
2.how might removing the flowering plants and replace it them with ferns affect the population numbers of the butterfly and the new species?
3. how might the building of the hotel affect the population of the new species?
Growing of ferns instead of flowering plants and building a hotel adversely affect the butterfly and species.
Dr. budai has bad reaction to the new fern that contractors plan on introducing into the environment because it will be grown instead of flowering plants which is necessary for the survival of butterfly.
Removing the flowering plants and replace it them with ferns negatively affect the population of the butterfly and the new species because butterfly feeds on the nectar of the flowers whose removal decrease the population of butterfly and those species which feed on butterfly also adversely affected due to unavailability of food source.
The building of the hotel adversely affect the population of the new species because habitat of that species will be destroyed so we can conclude that growing of ferns instead of flowering plants and building a hotel adversely affect the butterfly and species.

Semiconservative DNA replication means that
A. each daughter DNA molecule is composed of one original strand and one new strand.
B. the sequence of a DNA molecule is preserved as it is being replicated.
C. each strand of a double-stranded DNA molecule is replicated differently.
D. the cell can proofread its newly synthesized DNA only part of the time.
E. nucleotides are constantly being recycled as cells make DNA.
Semiconservative DNA replication means that each daughter DNA molecule is composed of one original strand and one new strand (Option A). It describes the mechanism of DNA replication.
In semiconservative DNA replication, both DNA strands separate and serve as templates to create new complementary DNA strands.
In consequence, each daughter cell has a molecule of DNA composed of an 'old' DNA template strand and a newly synthesized DNA strand.
The semi-conservative nature of DNA Replication was discovered by Meselson and Stahl.

Why are crystals in minerals formed from magma larger than mineral crystals formed from lava?
Answer:
Magma cools slowly inside Earth, which gives mineral crystals time to grow large enough to be seen clearly. Lava cools much more rapidly than magma when it is below the surface. In a cooling lava, mineral crystals do not have time to form and are very small.

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.
