Part I: Layers of the Epidermis
A. The following diagram of the epidermis has four distinct layers. In areas of the body
with thick skin, such as fingertips, palms, and soles, there is an additional layer
called the stratum lucidum. This layer consists of flattened, clear, dead cells, located
beneath the stratum corneum. To help you learn the layers of the epidermis, label
Figure 9-1 with the terms provided below.

Answer:

false

Explanation:

chemicals should never be reused because it cam affect the next experiment. always ask your teacher what to do with the materials.

Answer:

False

Explanation:

All chemicals after a lab experiment should be disposed of in the correct way (usually a container that is for hazardous waste). Failing to do so can be very dangerous as they've already been used

Answer:

Answer:

both

Explanation:

RNA is translated into protein on ribosomes. Protein synthesis is the name of this procedure. Large numbers of ribosomes are present in cells because protein synthesis is crucial to them. In addition to being attached to the endoplasmic reticulum, ribosomes also float freely in the cytoplasm (ER). So they re found in both.

Answer:

500g

Explanation:

0.5kg=500g

500/1 = 500g

There are 500 paper clips in a paper clip box that weighs 0.5 kg.

A paper clip may be defined as a type of material that is made up of steel or some other metal, but molded plastic is also used for binding up papers.

Weight of one paper clip = 1.0 g.

Number of grams in 0.5 kg = 500 g.

∴ Number of papers clips in 500 g = 500 × 1.0 = 500 paper clips.

Therefore, there are 500 paper clips in a paper clip box that weighs 0.5 kg.

Answer:

The correct answer is : surveying.

Explanation:

Paleo-anthropology is the study of the extinct primates, it is a sub branch of anthropology. It is focused on the human evolution and rise of the sub type of family of the other human or hominids.

Surveying is the one of paleoanthropoolgy practices that involves the finding the fossils of hominids on the surface of all around the globe by walking to compare it and study the evolution of human family.

Thus, the correct answer is- surveying.

Answer:

They each have vestigial structures.

Explanation:

Birds and humans have a common ancestor as they have homologous structures.

Vestigial structures are the organs that have some important functions in the past but now in present, they do not perform any function.

Both humans and birds have vestigial structures such as humans have an appendix and ear pinna and wings of flightless birds such as ostrich.

Hence, the correct answer is "They each have vestigial structures.".

Answer:

They each have vestigial structures.

C.the fertile offspring of individuals that are well adapted to their environment will make up the greater proportions of the next generation.

H.individuals better suited to their environment are more likely to survive and reproduce because

Natural selection refers to basic mechanism of evolution where by organisms develop traits or characters that will make them to adapt, survive and reproduce in their environments thereby transferring those traits or characters to their next generations.

It is survival and reproductive mechanism.

Answer:

To make an experiment where plants with thin cuticle are under two different treatments: normal conditions and water stress conditions

Explanation:

An experiment is a scientific procedure that enables to confirm (or reject) a hypothesis. Thus, it is possible to determine the effects of the cuticle on the survival of the plant by subjecting plants with thin cuticle to two experimental conditions (normal and water stress conditions), which can be used to determine if the differences in plant survival are statistically significant to support the hypothesis (e.g., the key role played by the plant cuticle). Moreover, it is important to note that it is imperative to include a control group in order to contrast with the obtained experimental results (e.g., to include plants with thick cuticle in both treatments).

The statement that an amoeba is a unicellular organism, is True.

An amoeba is a unicellular organism, which means that it is a single-celled organism. They are a type of protist, which are a diverse group of eukaryotic organisms that are not animals, plants, or fungi.

Amoebae are found in moist environments, such as soil, freshwater, and saltwater. They are able to move around by extending their cell membrane and cytoplasm, a process called pseudopodia. They use pseudopodia to capture food and to move to new locations.

Answer: C. Microarrys use tiny portions of double-stranded RNA fragments from a large number of genes.

Explanation:

A DNA microarray) is a solid surface to which a collection of DNA fragments is attached. The surfaces used to fix the DNA are highly variable and can be made of glass, plastic or even silicone. It involves placing thousands of gene sequences in specific locations on a glass slide called a chip. Microarrays basically miniaturizes processes that have been used in molecular genetics laboratories for years. So, a sample containing DNA or RNA is put in contact with the chip, and it allows the detection of DNA or RNA molecules by hybridization or adhesion of the molecules on the slide. The detection of the DNA or RNA adhered is made by different labels or colors that allow them to be detected under the microscope.

Microarrays are usually used to identify genes with differential expression under different conditions. For example, to detect genes that produce certain diseases by comparing expression levels between healthy cells and cells that are developing certain types of diseases. The matching of the complementary bases between the sample and the gene sequences on the chip produces a measurable amount of light. The areas of the chip that produce this light identify the genes that are expressed in that sample.

Then, in summary, the DNA chips are used to analyze the differential expression of genes, and the levels of thousands of genes are monitored simultaneously. And it measures the level of hybridization between the specific probe (probe) and the target molecule (target), indicated by fluorescence and through an image analysis, which indicates the level of gene expression.
