A snake has scaly skin to keep from drying out in the desert. A cactus has sharp spines and a thick stem that keep water in .Adaptations term describes such traits that help organisms survive.
In biology, there are three related definitions of adaptation. First, natural selection, a dynamic evolutionary process, adapts organisms to their environments, improving their evolutionary fitness. Second, it is a state that the populace has attained along that process. Thirdly, it is a phenotypic characteristic or adaptive trait that has been preserved and has evolved via natural selection and has a functional purpose in each individual organism.
History has recorded descriptions of adaptation going back to the time of the ancient Greek philosophers Empedocles and Aristotle. Natural theology of the 18th and 19th centuries saw adaptation as proof of the presence of a deity. Charles Darwin suggested that natural selection should be used as the explanation instead.

Which mutation caused Lucy immunodeficiency disease?
Hyper IgE syndrome, Job's syndrome is a rare condition with symptoms Lucy's had. A STAT3 gene mutation is the primary cause of the immunodeficiency, which affects approximately one person in a million.
In every tissue of the body, the STAT3 protein is active. It is necessary for life and plays a significant role in the growth and operation of many bodily systems. Signals for the maturation of immune system cells, particularly T cells and B cells, are transmitted by the STAT3 protein in the immune system. Additionally, the protein plays a part in cellular processes that support allergic reactions and is involved in the regulation of inflammation, one of the immune system's responses to infection or injury.

what system works with the respiratory system to circulate blood and oxygen throughout the body
The cardiovascular system works with the respiratory system to circulate blood and oxygen throughout the body. The cardiovascular system includes the heart, blood vessels, and blood.
The cardiovascular system works in conjunction with the respiratory system to ensure that oxygen is delivered to the body's cells and that carbon dioxide is removed. When we breathe in, oxygen enters the lungs and is transferred to the blood, where it binds to hemoglobin. The oxygen-rich blood is then pumped by the heart to the body's cells, where it is used to produce energy. At the same time, respiratory system carbon dioxide, a waste product of cellular metabolism, is removed from the cells and carried cardiovascular system by the blood to the lungs, where it is exhaled. This process, known as respiratory system, is a continuous respiratory system cycle that ensures the body's cells receive the oxygen they need to function properly and that waste products are removed.

INTRO TO CELL RESPIRATION OVERVIEW POGIL: All cells need energy all the time, and their primary source of energy is ATP. The methods cells use to make ATP vary depending on the availability of oxygen and their biological make-up. In many cases the cells are in an oxygen-rich environment. For example, as you sit and read this sentence, you are breathing in oxygen, which is then carried throughout your body by red blood cells. But, some cells grow in environments without oxygen (yeast in wine-making or the bacteria that cause botulism in canned food), and occasionally animal cells must function without sufficient oxygen (as in running sprints). In this activity you will begin to look at the aerobic and anaerobic processes that are used by all organisms to produce ATP. Which statement is NOT true based on this intro
The products formed as a result of cellular respiration are ATP, water and carbon dioxide.
The cells require energy to perform all their cellular functions. The source of energy for them is ATP which is adenosine triphosphate. The amount of ATP which is produced by a cell depends on its requirement and also on the amount of oxygen that is available.
Depending on whether a particular organism requires oxygen or not, they can be classified as aerobic and anaerobic. Aerobic organisms are the ones which require oxygen whereas anaerobic organisms do not require oxygen. The reaction for cellular respiration can be represented as:
C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O + ATP
Carbon dioxide, water and ATP are formed as products in this reaction.

Compare the overall excretory process in plants vs animals in terms of ; organs used and are they specialized?
Answer:
Stomata.
Explanation:
Plants do not have specialized excretory organs like animals. The plant body produces excess carbon dioxide and oxygen which are excreted from the plant through the small opening present on the underside of the leaves called stomata. In the process of photosynthesis, plant produces oxygen and glucose in which glucose is stored in the body whereas oxygen releases through stomata while on the other hand, in respiration process, plant produces carbondioxide gas that is also released through stomata.
looking at model 1, the other molecules that appear to be high potential energy molecules (free energy carriers) during cellular respiration to carry electrons to oxidative phosphorylation are
The additional compounds that seem to be high potential energy molecules for transporting electrons to oxidative phosphorylation during cellular respiration include The majority of ATP molecules created during cellular respiration come from oxidative phosphorylation.
The process through which organisms combine oxygen and food molecules, direct the chemical energy of those components toward life-sustaining processes, and eliminate carbon dioxide and water as waste is known as cellular respiration.
The process of breaking down sugar in the presence of oxygen and releasing energy in the form of ATP is known as cell respiration, and it takes place in the mitochondria of living things (animals and plants). Water and carbon dioxide are emitted as waste during this procedure.
Through the mitochondrial electron transport chain, ATP production is connected to electron transfer and corresponding oxygen consumption through the process of oxidative phosphorylation.

What will happen to enzyme if active site loses its shape?
The substrate's affinity for binding will decline, causing the enzyme to either complete the reaction at a slower rate than usual or not at all, depending on how much the active site has changed.
Proteins known as enzymes serve as biological catalysts and speed up chemical reactions. Substrates are the substances that interact with enzymes, and the enzyme changes the substrates into products, which are other molecules. Enzyme catalysis is required for the bulk of cellular metabolic processes to proceed at speeds quick enough to support life. An enzyme is required for each step in the catalysis of metabolic processes. It is acknowledged in the fields of pseudoenzyme analysis, enzymeology, and the study of enzymes that some enzymes have evolved without the capacity to perform biological catalysis.

How should the sperm motility be categorized in this microscopic field of a semen sample viewed at 400X magnification
The sperm motility can be categorized in this microscopic field of a semen sample viewed at 400X magnification - Non-Progressive motility = 2; immotile = 3
Fast and slow progressive motility are calculated from the speed at which sperm migrating the flagella migrate at a certain volume percentage (range 0% to 100%) by counting 200 sperm.
Decreased sperm motility may be a symptom of disorders associated with male accessory gland secretion and the sequential ejection of these glands.
Routine sperm analysis should contain at least 50% progressively motile class A and B sperm. Sperm viability should be checked if more than 50% of the sperm are fixed. Persistent reduced mobility is a good indicator of infertility and is actually the more important outcome when making decisions about treatment options for couples.

Blocks of genetic material that do not recombine and are passed on for generations are called
a) phenotypes b) genotypes c) karyotypes d) haplotypes
Blocks of genetic material that do not recombine and are passed on for generations are called haplotypes.
A haplotype is a set of DNA variants along a single chromosome that tend to be inherited together. Because they are close together on the chromosome and recombination between these variants is rare, they are usually inherited together.
The haplotypes represent sequences along the chromosome that are either conserved intact or separated over time by recombination. This basic concept has led to the development of methods to extract information about recombination to help researchers identify disease-causing genes and loci.
In the genome, alleles of closely spaced variants on the same chromosome tend to occur together more frequently than would be expected at random. These allelic blocks are called haplotypes.

What is the genotype of individual II 2?
When two alleles in a genotype are the same, the genotype is said to be homozygous; when the two alleles are different, the genotype is said to be heterozygous. Genotyping is the term for the process of identifying a genotype.
A person's genotype is made up of all the alleles they have for a certain gene. The sum of a person's attributes or observable characteristics is their phenotype. The phenotype of an organism is only impacted by its genotype, which is directly inherited from its parents. It is possible for a child to have genotype "ii" because parents with type B will have either BB or Bi. A father with type "O" can have a child with genotype "ii" because type "O" is determined by allele I.
