D) sympathetic.
The sympathetic nervous system is a division of the autonomic nervous system that is responsible for preparing the body for "fight or flight" in response to stress or danger.
The sympathetic nervous system activates the "stress response," which involves a series of physiological changes that help the body respond to a perceived threat.
One of the functions of the sympathetic nervous system is to stimulate the arrector pili muscles, which are small muscles attached to the base of hair follicles. When the arrector pili muscles contract, they cause the hair to stand on end, giving you "goosebumps." This is an evolutionary response that helped animals appear larger and more intimidating when confronted with a threat.
The other options in the question are not related to the sympathetic nervous system or the arrector pili muscles.
The parasympathetic nervous system is the other division of the autonomic nervous system and is responsible for promoting relaxation and rest.
Afferent neurons are sensory neurons that transmit information from the body to the central nervous system.
The dorsal column refers to a group of nerve fibers in the spinal cord that carry sensory information to the brain.
The somatic nervous system is the division of the peripheral nervous system that controls voluntary movement and sensory information from the body.

Endometrial cells grow in response to:a) Hormones secreted from the pituitaryb) Hormones secreted from the ovaryc) Hormones secreted by the uterusd) Body temperature changes
Endometrial cells grow in response to (b) hormones secreted from the ovary.
Endometrial cells make up the inner layer of the uterine lining (endometrium) and take part in uterine activities. The woman's current menstrual cycle affects how many cell layers there are. In the top layer of the endometrium are epithelial stromal cells, and below that is a layer of simple tubular glands (glandulae uterinae).
Endometrial cells have a big impact on how the endometrium functions. Near the uterine cavity lies the functional layer. During the first half of the previous menstrual cycle, this layer is constructed after menstruation has ended. Estrogen (follicular phase of the menstrual cycle) stimulates proliferation (growth or creation of the cells), while progesterone stimulates subsequent alterations in this layer.

Most E. coli antisense RNAs work with a protein called ______ to regulate their target mRNAs.
A. CAP
B. MicF
C. Hfq
D. None of the choices are correct.
Most E. coli antisense RNAs work with a protein called Hfq to regulate their target mRNAs.
The Hfq protein (also known as HF-I protein) encoded by the Hfq gene was discovered in 1968 as an Escherichia coli host factor that is important for bacteriophage replication. It is now clear that Hfq is an abundant bacterial RNA-binding protein with many important physiological roles, usually mediated through interactions with Hfq-binding sRNA.
Hfq mediates its pleiotropic effect through multiple mechanisms. These interact with regulatory sRNAs and facilitate their antisense interactions with their targets. It also acts independently to modulate mRNA decay (directing the mRNA transcript to decay) and also acts as a repressor of mRNA translation.

Bad-tasting, bad-smelling, toxic, or stinging-prey species advertise their characteristics using ____________________.
Bad-tasting, bad-smelling, toxic, or stinging-prey species advertise their characteristics using warning coloration.
Superb examples of evolutionary adaptations are warning colour and mimicry. Because we are extremely visual mammals, we can easily comprehend the outcomes of visual adaptations like these. The purpose of warning colour is to prevent prey from assaulting species with active defences.
Warning colours are often (but not always) bright and noticeable. Bright, contrasty warning patterns, like traffic signs, are generally simpler to learn: they are advertising colours.
In practise, brightly coloured creatures known to be guarded, such as wasps and distasteful Heliconius butterflies, are considered to be aposematic - despite the fact that little experimental data suggests they are simpler to learn.
To a first approximation, learning a warning colour necessitates that the per capita loss during learning reduces as the number of warning colours in a population increases. After been irritated by a warning pattern, predators will learn to avoid other individuals with the same colour pattern, regardless of density.
As a result, the proportion taken decreases as the density of the warning-colored prey increases. As a result, warning colours provide a frequency-dependent fitness benefit that grows as the frequency of warning colours grows. Polymorphisms are hence not expected, and are seldom found, within populations of warningly-colored animals.
When the bulk of a predator population recognises the warning pattern, crypsis should become unfavourable, and hiding should no longer be advantageous.

What are three examples of genetic traits that you inherited from your parents?
Three examples of genetic traits passed down from parents to their children are intelligence, endurance, and temperament (emotions).
Inheritance or heredity is a decrease in traits that are passed down from parents or parents to children or offspring. The characteristics of a living thing are passed down through male sex cells and female cells.
The part of the cell that is responsible for reducing the inheritance of properties is the nucleus of the cell. Inside the cell nucleus, there is something called a chromosome which functions as a hereditary substance. Factors carrying traits that play an important role in the process of inheritance of these traits are called genes.
Egg cells and sperm cells each carry their genes or chromosomes. The fusion results in the formation of a zygote. The zygote that is formed contains a combination of genes and chromosomes from the parent (parents). This explains how the physical characteristics of the parent (parents) can be passed on to their offspring (children).

Pollen from a flower of a homozygous green (GG) watermelon plant is used to pollinate a flower from a heterozygous green (Gg) watermelon plant. What percent of the offspring of this cross will bear striped watermelons
In watermelon plants, some have solid green fruit (G) and some have striped fruit (g). When a watermelon plant that only has the solid green fruit (GG) is used to pollinate a plant that has both solid and striped fruit (Gg), then 50% of the offspring will have striped watermelons.
The 50% of the offspring of this cross will bear striped watermelons because the heterozygous green (Gg) watermelon plant has one dominant allele (G) and one recessive allele (g).
When the pollen from the homozygous green (GG) watermelon plant is used to pollinate the heterozygous green (Gg) watermelon plant, the offspring will have a 50/50 chance of inheriting either the dominant allele (G) or the recessive allele (g).
