NEED HELP FAST!! Question 8(Multiple Choice Worth 3 points) (01.04 HC) A group of students performed an experiment to prove the

law of conservation of energy. In the experiment, a flask containing water at room temperature was shaken vigorously for a few minutes. The table shows a partial record of the temperature of the water before and after shaking. Experimental Record Temperature Before Shaking 20 °C After Shaking Unknown What best predicts the unknown temperature? Less than 20 °C because the total energy of the system after shaking is lower Greater than 20 °C because the total energy of the system after shaking is higher Less than 20 °C, because the mechanical energy from shaking transforms to thermal energy Greater than 20 °C, because the mechanical energy from shaking transforms to thermal energy

In familial hypercholesterolemia, individuals homozygous for the allele causing the disorder completely lack receptors on liver
JulsSmile [24]

Answer:

The correct answer is - incomplete dominance.

Explanation:

A inheritance pattern that is characterized by pattern in which the one allele is not completely dominant over the its recessive variant of the allele and due to its incomplete dominance a third phenotype expressed over, termed as the incomplete dominance.

In the case of the familial hypercholesterlemia, it is genetic disorder in which the individual lacks the receptors on liver cells remove cholesterol from the blood. This condition occur in the homozygous allele case. In normal people have receptors normal while in heterozygous condition individual have half of the total receptors.

Thus, it is the case of incomplete dominance.

"During embryonic development red blood cells begin to develop in patches called blood islands. The blood cells secrete growth f
Elanso [62]

Answer:paracrine

Explanation:glands are specialized tissues that secrete specific chemicals substances.these substances may be enzymes,hormones or lubricating fluid.glands secretes their their products through several mechanisms.some involve the use of ducts ,while others do not.

In paracrine secretion,the secretory products reach their target cells by diffusion through the extracellular space or adjacent connective tissue.

Paracrine secretion do not use ducts.

Similar to paracrine is the endocrine ,in which the secretory products goes through the basal lamina ,into the underlying connective tissue and into the vascular syatem.they too do not use ducts

Who devised a technique for determining the blood group of a dried bloodstain, which he applied to criminal investigations?.
Dominik [7]

Landsteiner Bertillon devised a technique for determining the blood group of a dried bloodstain, which he applied to criminal investigations.

<h3>What about blood group?</h3>
  • According to the presence or absence of antibodies and hereditary antigenic compounds on the surface of red blood cells, blood is classified according to its type.
  • Depending on the blood group system, these antigens could be proteins, carbohydrates, glycoproteins, or glycolipids.
  • The genes that a person got from their parents determine what blood type they have.
  • There are numerous systems for classifying blood types, but ABO is the most popular one.
  • The ABO group is divided into four main categories: A, B, O, and AB.
  • There are eight more blood types within these groupings.
  • Each of the eight blood types has a particular ability to save lives.
  • The majority of people (37% of the population) have the blood type O+, which is the most prevalent. This indicates that there is a greater need for this blood type for blood transfusions.
