Answer:
Why is healthy skin important? Healthy skin is important because it is your first line of defense against bacteria and other pollutants in the environment. Healthy skin is more resilient when faced with external stresses, serves as an important sensory organ and helps to regulate our body temperature.
The outermost layer of skin, called the epidermis, produces a thin barrier layer called the stratum corneum. This layer varies throughout the body in its structure, thickness, composition and functional properties. For example, the skin on your palms and soles is thicker than on your face.
Skin changes such as wrinkling are one of the physical alterations most readily associated with aging. It may surprise you that the outer layer of the skin, the stratum corneum, changes very little as we age. The main changes occur at a deeper level. Collagen, a basic chemical building block of skin and connective tissue, decreases with age.

A student observes that a plant has droopy leaves and stems and infers that the rate of photosynthesis has slowed in the plant. Which statement provides evidence to support the student’s inference?
Answers
Answer:
A. The water pressure in the plant's vacuole is low, and without water, the chloroplasts cannot convert carbon dioxide to glucose during photosynthesis.
Explanation:
Photosynthesis occurs on chloroplasts which are located on the surface of leaves. Photosynthesis is the conversion of carbon dioxide, water, and light energy to produce glucose and oxygen for plants.
The vacuoles inside the plant's cell contain stored food and absorb water through osmosis. Water in the vacuole has more solutes than water outside the vacuole. This causes the Turgor Pressure which the vacuole impacts on the plants. If the reverse becomes the case, water is lost from the vacuole causing it to shrink.
Flaccidity of the vacuole and the cell wall will cause the chloroplasts where photosynthesis occurs to shrink.
"CRISPR" stands for Clustered Regularly Interspaced Short Palindromic Repeats, which are the hallmark of a bacterial defense system that forms the basis for CRISPR-Cas9 genome editing technology. In the field of genome engineering, the term "CRISPR" or "CRISPR-Cas9" is often used loosely to refer to the various CRISPR-Cas9 and -CPF1, (and other) systems that can be programmed to target specific stretches of genetic code and to edit DNA at precise locations, as well as for other purposes, such as for new diagnostic tools. How can this tool be used to alter genes in various organisms?
Answers
Answer:
by designing short guide RNAs (sgRNAs) customized to target genes of interest in the cells of these species
Explanation:
The CRISPR-Cas9 editing system is a versatile and powerful genome engineering tool for editing genomes, which can be directed to alter almost any DNA sequence in order to modify gene function. This system consists of an endonuclease protein (Cas 9) that cuts DNA at specific sites guided by a short guide RNA (sgRNA), which binds by base complementarity to the target sequence. This sgRNA must be designed with efficiency and specificity to target genes of interest. In consequence, the CRISPR-Cas9 genome editing system produces DNA double-strand breaks which may be repaired by 1- error-prone nonhomologous end joining (NHEJ) or 2-homology-directed repair (HDR) DNA repair pathways. According to the DNA repair pathway that has been activated, it is possible to trigger genetic modifications in the cells of different species (i.e., plant cells, animal cells, human cells, etc).

Hope this helps!
According to the picture given below, the Caribou is an individual that is living in a particular geographical location, while all other groups of individuals belonging to different species in that area represent a community.
What is Community?A Community may be defined as a group of individuals belonging to different species living in the same area at a given time.
The individual is the unit of the population, while the population is the unit of evolution. This form of evolution is significantly required in order to construct a community where the different groups of individuals of different species are gathered in such a way that one depends on another.
Therefore, according to the picture given below, the Caribou is an individual that is living in a particular geographical location, while all other groups of individuals belonging to different species in that area represent a community.

Answer:
A two-word name for organisms where the word is the genus and the second word is the species
Explanation:
Binomial nomenclature is the system biologists use to name species of living beings. When we translate this term, we get the two-name naming system. This tells us a lot about how species are named - their name consists of two components. The first component is the name of the genus the species belongs to and the second is the name of the species. For example, the scientific name used for cats is Felis catus. Felis is the genus and the species is catus.
in which direction do particles in a solution move during passive transport
Answers
During the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending. The passive transport is seen in the cell too.
What is the importance of the different types of transportation?In the cell, different types of transport are seen, such as active transport and passive transport; in active transport, energy is used, while energy is not used in passive transport. The movement of molecules across the cell plasma membrane is important because it allows cells to get rid of unwanted molecules. Passive transport does not require energy, and many nonpolar small molecules and gases can cross the lipid plasma membrane barrier and go into and out of the cell while, in this passive transport process, they save the cell's energy.
Hence, during the passive transport, the particles move from a higher concentration to a lower concentration without the need for energy expenditure or spending.

Explain how specific proteins are formed from a strand of mRNA.
Answers
Answer:
During translation, ribosomes move along an mRNA strand, and with the help of proteins called initiation factors, elongation factors, and release factors, they assemble the sequence of amino acids indicated by the mRNA, thereby forming a protein.
Explanation:
Answer:
Explanation:
Los ARN mensajeros, también conocidos como ARNm, son uno de los tipos de ARN que se encuentran en la célula. Éste en particular, como la mayoría de los ARN, se sintetiza en el núcleo y luego se exporta al citoplasma, donde la maquinaria de traducción, la maquinaria que realmente fabrica las proteínas, se une a las moléculas de ARNm y lee en ellas el código para producir una proteína específica. Así que en general, un gen, el ADN de un gen, puede ser transcrito en una molécula de ARNm que puede acabar dando lugar a una proteína específica.

about artificial selection, determine if YOU think the benefits of artificial selection outweigh the disadvantages.
PLEASE HELP!!!!
Answers
Answer:
What YOU think
Explanation:
That's what it asks, but here are some points to help you along your way: Artificial selection has brought about the extinction or overpopulation of certain species. This can be seen in the avocado or banana industry. Consumers like the smaller, sweeter species of avocadoes. This caused that species to explode and the old ones to become endangered as farmers grew only that type and bred them selectively. Consumers like the smaller, less mushy, less sweet banana species, so now an amazing species of banana is extinct because the forests that used to have them now no longer exist or were changed to grow only that type of banana. Flip it to the animal side, and it's the same story. Those turkeys that the president "Saves" every year? because of artificial selection, that turkey dies a few weeks later because he grew too plump. Why? Because those turkeys are artificially selected to grow much larger than a normal turkey, and their lifespan is not in mind as they are grown for meat.
