The skin performs many functions including protection, regulation of body temperature and sensation of surroundings. However, it does not produce blood cells, which is a function performed by the bone marrow.
The skin, also known as the integumentary system, performs a number of essential functions that help maintain our health and wellbeing. These include protecting our bodies from external hazards, regulating body temperature, and allowing us to sense our surroundings. However, one function your skin does not perform is the production of blood cells. This is the role of the bone marrow, a soft tissue inside your bones. Thus, production of blood cells is not a function of the skin.

Answer:
He should get his mitochondrial haplotype sequenced, given the genetic variation in mitochondrial sequences compared to Y chromosomes.
Explanation:
A haplotype is a group of genes within an organism that was inherited together from a single parent. The word "haplotype" is derived from the word "haploid," which describes cells with only one set of chromosomes, and from the word "genotype," which refers to the genetic makeup of an organism.
Genetic variation is a term used to describe the variation in the DNA sequence in each of our genomes. Genetic variation is what makes us all unique, whether in terms of hair color, skin color or even the shape of our faces.
The typical metazoan mitochondrial DNA (mtDNA) is a double-stranded circular DNA molecule, which encodes a conserved set of 37 genes, including 13 protein-coding genes (PCGs) plus the two ribosomal RNA (rRNA) genes and 22 transfer RNA (tRNA) genes.
This, together with other special characteristics such as faster evolutionary rates than nuclear genes, presumed maternal inheritance, and absence of recombination makes mitochondrial DNAs one of the most popular targets for population genetics studies and accurate identification.
Answer:
The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth's surface, is called the exosphere.
The red line on the figure below shows how temperature varies with height (the temperature scale is given along the bottom of the diagram). The scale on the right shows the pressure. For example, at a height of 50 km, the pressure is only about one thousandth of the pressure at the ground.
The correct answer is option B, kingdom→phylum→class→order→family→genus→species
Reason:
There are basically seven orders of classification in Linnaeus's Classification System (in present time) arranged in descending order
Kingdom→phylum→class→order→family→genus→species
The Domain is the largest and most inclusive group and consists of organisms that share few characteristics while the species is the smallest and most exclusive group and consists of organism that possess similarity up to an extent where they can breed among themselves to produce offsprings.
B. Knowledge and valuable resources are shared among scientists.
C. An experiment is repeated several times to verify the results.
D. Multiple forms of evidence are used to support a conclusion.
the right answer is b
