Biology

Answer:

Accurate - Yes

Precise - Yes

Explanation:

Accuracy and precision are two ways to detect the closeness of measured values in an experiment. However, these two terms do not mean the same thing.

Accuracy of a measurement refers to how close a measurement (experimental values) is to a true or actual value while the precision of a measurement refers to how close the experimental or measured values are to one another.

Note that, a measurement may be accurate but not precise or be precise but not accurate.

In the case of the dart board in the image, it is evident that the measured values (represented by darts) are close to the middle target (represents the known or accepted mark). Hence, the measurements are said to be ACCURATE. Likewise, the measured values are also close to one another, meaning that they are PRECISE.

Therefore, the measurements are both precise and accurate.

Explain the characteristics scientists use when observing organisms and placing them in the six kingdoms.
crimeas [40]

Answer:

Classification of organisms is done while considering many factors such as:

Cell type- whether the organism is prokaryotic or eukaryotic

Cell structure- This includes both the presence and composition of the cell wall

Body type- whether the organism is multicellular or unicellular

Mode of nutrition- the method through which the organism achieves its nutritional requirement, by consuming other organisms (heterotroph) or making its own food (autotroph)

How can one set of parents produce 19 children who all look different and unique but yet have some similar characteristics or tr
arsen [322]

Polygenic inheritance. The characteristics of a person aren't controlled completely by a single gene, but rather several genes that generally only make a small contribution to how the child turns out in the outcome. At one point there was a study that showed over 400 genes were linked to height, so imagine any other characteristics of a person. Environmental effects also serve a large purpose in how a child is to turn out. These children may all be growing up in the same environment, however that's not to say they all grow up the same. They could all be treated the same way and react differently to it, this counts both for physical and mental traits. All human's features such as eye colors, hair color and height are determined by several different genes. As an example, there are around 2 major eye color genes, however there are also around 14 different genes that actually contribute in determining a person's exact eye color. Some are bound to look the same, as they have the same parents, however, just because they have the same parents doesn't mean they all will look exactly alike.

Helga [31]

The result would be twenty-five percent yellow and the blue ones will be fifty percent while green is twenty-five percent. If an F2 generation is derived from the two true-breeding parents which have the same trait for different characteristics. The recessive phenotype would be hundred percent of true breeding if they fertilized themselves. A recessive trait is expressed when the genotype is only homozygous recessive.
