Answer:
vulnerable would be the answer
Currently, there are more than 1,300 species in the US that are either endangered or threatened. Species that are in risk of going extinct include those plants and animals that have become so scarce.
What Endangered Species Act, as a vulnerable species?A species that is endangered is one that is in danger of going extinct. The two main factors that cause a species to become endangered are habitat loss and genetic diversity loss.
Natural occurrences may result in habitat loss. For instance, dinosaurs had their home removed some 65 million years ago.
A species that has been designated as vulnerable by the IUCN is one that is predicted to go extinct unless the conditions that jeopardize its existence and reproduction change.
Therefore, A species that is naturally rare or that has been depleted to dangerous levels is known, according to the Endangered Species Act, as a(n)(vulnerable) species.

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.

Which of the following statements defines ovulation?
Ovulation is when an immature ovum develops into a mature ovum.
*Ovulation is the release of a mature ovum, which occurs once each month.
Ovulation is the production of an ovum that occurs each month.
Ovulation is the monthly discharge of the uterine lining.
Answer:
b. Ovulation is the release of a mature ovum, which occurs once each month.
Explanation:is correct. post protected
Ovulation is the release of a mature ovum, which occurs once each month. The correct option is B.
What is ovulation?The process of an egg being released from the ovary is called ovulation. The egg is released and travels down the fallopian tube, where it remains for 12 to 24 hours before being fertilised.
Although ovulation is necessary for conception, more than simply an egg is required. For instance, there needs to be a clear path to the egg. A blocked fallopian tube prevents pregnancy from happening.
Around the time of ovulation, you could notice that your cervical mucus is wetter, clearer, and more slippery. After ovulation, there is a slight increase in body temperature that you might be able to measure with a thermometer.
Thus, the correct option is B.

The best advantage of sexual reproduction is?
It is more efficient than asexual reproduction
It is safer than asexual reproduction
It results in identical offspring

Answer:
it increase the genetic diversity through meiosis , crossing over and random assortment of chromosome
Explanation:
There are two main processes during sexual reproduction: meiosis, involving the halving of the number of chromosomes, and fertilization, involving the fusion of two gametes and the restoration of the original number of chromosomes.
while asexual reproduction doesn't form any reproduction that involves neither meiosis nor fusion of gametes

placing its basic parts together like pieces of a puzzle.
The structure of DNA resembles a twisted ladder because both strands are linked by hydrogen bonds.
What is DNA?Deoxyribonucleic acid (DNA) is a double helix composed of two long chains of nucleotides linked by hydrogen bonds.
In DNA there exist only four different types of nucleotides (i.e., Guanine, Cytosine, Thymine and Adenine).

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]

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.
