Answer:

Factor Analysis

Explanation:

Factor Analysis is a statistical procedure that can be used to identify clusters of behaviors (such as verbal skills, intelligence) that are related to a trait.

Factor analysis helps to accumulate a lot of data in many variables into a few variables which can be used for further analysis or study. The aim of factor analysis is to aggregate individual behaviors into a minimized number of factors.

Where in the plant are the hormones auxins produced? (Select all that apply.)

Bezzdna [24]

Answer:

Stems and root

Explanation:

Auxins facilitate stem elongation while inhibiting axillary bud formation, ensuring apical dominance. The root, branches, and stem and tip all contain them. Hydroxy Acetic Acid is a perfect example. Auxin is indeed a growth hormone that facilitates cell elongation and is formed in the stem tip.

What determines how quickly blood dries?

lara [203]

Blood is made up of red and white blood cells, platelets and plasma. The plasma consists of water (mostly) and dissolved nutrients. When blood is exposed to air, the blood will clot, due to aggravation of the platelets. Then you get a forming scab that will help heal the part that the blood is being exposed from.

Your BFF is a red-headed, left-handed, blue-eyed girl. She finds out that you are taking Human Genetics and wants you to explain

Pavlova-9 [17]

Answer:

Red hair, left handed, and blue eyes are recessive traits.

Any trait has its two allele, dominant and recessive. Dominant trait allele if present with the recessive allele, then the phenotype will be of dominant allele.

Suppose A = dominant allele for brown color hair, a = recessive allele for red color hair.

As mentioned above red color hair is recessive in nature. for the recessive traits to show, the alleles should be recessive only.

Aa (brown hair) (parent 1) is crossed with Aa (parent 2) (brown hair). They both have gametes A and a.

Their children will have genotype AA, aa, and Aa. AA = brown color, aa = red color hair, and Aa= brown color hair.

Same case goes with the left hand and blue eyes traits.

So, the girl parents must be having recessive alleles for all the traits, and she must have inherited all the recessive allele only.

1. Name the two major divisions of the nervous system; list the organs/tissues found in each.

Jet001 [13]

Answer:

1.Structural Divisions of the Nervous System. The nervous system can be divided into two major regions: the central and peripheral nervous systems. The central nervous system (CNS) is the brain and spinal cord, and the peripheral nervous system (PNS) is everything else.

2.Like the nervous system as a whole, the peripheral nervous system also has two divisions: the sensory division and the motor division. The sensory division of the PNS carries sensory information from the body to the central nervous system.

3.Sensory receptors with corresponding stimuli to which they respond.

Receptor Stimulus

Apmullae of Lorenzini (primarily function as electroreceptors) Electric fields, salinity, and temperature

Baroreceptors Pressure in blood vessels

Chemo receptors Chemical stimuli

Electromagnetic radiation receptors Electromagnetic radiation

Electroreceptors Electrofields

Hydroreceptors Humidity

Infrared receptors Infrared radiation

Magnetoreceptors Magnetic fields

Mechanoreceptors Mechanical stress or strain

Nociceptors Damage or threat of damage to body tissues (leads to pain perception)

Osmoreceptors Osmolarity of fluids

Photoreceptors Visible light

Proprioceptors Sense of position

Thermoreceptors Temperature

Ultraviolet receptors Ultraviolet radiation
