D) Pituitary


The reason for the answer being choice D is because the pituitary gland is a small pea-sized body attached to the base of the brain. The pituitary gland is important in controlling growth and development and the functioning of the other endocrine glands.

Thyroid Gland; the pituitary is for your hormones and the pancreas is for insulin and is located in your torso area not in the throat area, and the adrenal glands are located on your kidney, leaving the thyroid located in your windpipe.

AfilCa [17]

Yes! a region of the body with greater sensory acuity to have cutaneous receptors with large receptive fields, or small receptive fields.

The sensory receptor located in the skin is known as a cutaneous receptor ( the dermis or epidermis). The somatosensory system includes them. Mechanoreceptors (pressure or distortion), nociceptors (pain), and thermoreceptors are cutaneous receptors (temperature). The lowest spatial resolution is found in the thigh and calf area, whereas the fingertips have the highest spatial resolution (and the smallest receptive fields) (and largest receptive fields). Two-point discrimination threshold measurements can be used to assess the spatial resolution in response to light touch stimuli.

study examines the ACTN3 genetic alleles R and X, also associated with fast-twitch muscles. Of the people in this sample, were c
Kruka [31]

Answer: Yes, the samples of R and X of α-actinin-3 (ACTN3) R577X polymorphism provided evidence that the two options are not equally likely Conduct the test using a test for a proportion, using where represents the proportion of the population classified R.  

Explanation: On one hand, from the reports of the following researcher; (North et al., 1999), (Gomez-Gallego et al., 2009; Yang et al., 2003), (Vincent et al., 2007) and (Kikuchi et al., 2014) supported that α-actinin-3 (ACTN3) R577X polymorphism is associated with muscle fibre type for power, elite performance, important for anchoring actin and plays a regulatory role in coordinating muscle fibre contractions.  

On the other hand, researchers such as Erskine et al. (2014), on 51 untrained healthy Caucasian males, Delmonico et al. (2007) studied an association between the ACTN3 genotype and training responses in a large Caucasian population of 157 relatively healthy sedentary Caucasian men and women, Gentil et al. (2011) detailed the outcomes of 141 young men, Pereira et al. (2013) reported the influence of ACTN3 polymorphisms and ACE I/D alone and in combination with muscle strength, power, and functional phenotype in older Caucasian women following 12 weeks of high-speed power training and Lima et al. (2011), conducted a study of 246 women (age 66.7 ± 5.5 years) agreed that in healthy relatively young sedentary Caucasians that both the ACE I/D and ACTN3 R577X polymorphisms (alone or in combination) were found to be associated in the baseline muscle strength, muscle strength resistance training, thickness of muscles and athletic status.  

However, the X allele, which is associated with the absence of ACTN3 protein, is suggested to impair the performance of high force/speedy muscle contractions. Using (Gentil et al., 2011) as the control experiment, the sample of 141 men performed two resistance training sessions per week for 11 weeks. The Participants were tested for 1-repetition maximum (1RM) bench press, knee extensors peak torque and knee extensors muscle thickness at baseline and after the training period. Consequently, genotype distribution was 34.4% for RR, 47% for RX, and 18.6% for the XX genotype. Drawing an inference from the to the results, the R577X polymorphism at ACTN3 was not associated with baseline muscle strength or the muscle strength response to resistance training. However, only carriers of the R allele showed increases in muscle thickness in response to training.  

Exceptions: (Clerkson et al, 2005) posited that women with RR genotype had a greater increase in muscle power than the men while in Delmonico et al (2007) disputed that claim by saying that women with XX genotype have greater relative responses than men.

In the practice of ________, scabs from smallpox victims were used to immunize susceptible individuals against smallpox.
Andreas93 [3]

Answer: Variolation

Explanation:

Variolation can be defined as the condition in which the inocolutaion of the individuals with the infectious materials, scabs or pulses from the smallpox victim.

This was introduced by the route of nasal passage or injected intravenously. The infection that developed because of this was less than normal and it provided protein against more serious disease.

Hence, the correct answer is Variolation.

What is the difference between a vascular and a nonvascular plant? In your answer, discuss how water moves in each type of plant
dexar [7]

Both plants have separate tubular tissues like Xylem and Phloem to transport food, minerals, and water, right? Those are called the vascular plants. So for those that don't show this kind of differentiation of the tissue, they're called the non-vascular plants.

Water and the other nutrients just move through the plants' body, cell by cell. The plants can get water this way but only if the plants' body is no more than a few cells thick.
