Answer;
-Projection level
-Projection level controls intermediate relay for incoming and outgoing neurons.
Explanation;
The levels of motor control include; segmental level, projection level and precommand level.
-The segmental level is the lowest level of motor hierarchy. It consists of segmental circuits of the spinal cord, Its circuits control locomotion and specific, oft-repeated motor activity. These circuits are called central pattern generators (CPGs).
The projection level consists of: Cortical motor areas that produce the direct (pyramidal) system, and Brain stem motor areas that oversee the indirect (multineuronal) system
. It helps control reflex and fixed-pattern activity and houses command neurons that modify the segmental apparatus.
Precommand level; Cerebellar and basal nuclei systems that:
-Regulates motor activity, precisely start or stop movements, coordinate movements with posture, Block unwanted movements
, and Monitor muscle tone.
I just have a question, are you in seventh grade? I keep my binders from past years and I remember learning this, but don’t know if that’s the grade I learned it in, are you?
Complementary pairing goes like this:
A pairs with T and
C pairs with G. Nothing about this changes unless you get to mRNA (But we won't go into that) :)
So if you have a strand that goes TCG GA then your pairing will look like this:
T A
C G
G C
G C
A T
Hope this helps!! :)

Explanation:
Sexual reproduction is the kind of reproduction that requires two organisms (male and female) to form an offspring. The male organism produces gametes called SPERM while the female organism produces gametes called EGG. These two gametes come together in a process called FERTILIZATION to produce a zygote, which develops into an offspring.
In sexual reproduction, gametes are produced by organisms involved via a process called MEIOSIS. Meiosis, however, reduces the chromosome number of the gametes by half. However, one process unique to only meiosis and sexual reproduction is called CROSSING OVER.
Crossing over is the process whereby chromosome segments is exchanged between non-sister chromatids of homologous chromosome. This process causes a recombination of chromosomes (alleles) in such a way that the gametes will be genetically different from the parent organisms (genetic variation). According to this question, sexual reproduction leads to more genetic variation than asexual reproduction due to the process of CROSSING OVER that occurs in sexual reproduction.
