Which of the following attributes of and organism cannot be seen by observing the organism?
A.phenotype
B.genotype
C.traits
The attribute of an organism that is not directly observable is the genotype. While phenotype and traits often manifest in observable ways, genotype refers to the genetic makeup, which requires specific tests to investigate.
Explanation:Out of the given options (phenotype, genotype, and traits), the attribute of an organism that cannot be observed just by looking at it is the genotype. Phenotype is the outward, physical manifestation of the organism. These include traits such as height, color, and shape which can definitely be seen by physical observation. Traits, generally speaking, refer to the individual characteristics of an organism, many of which can also be observed externally. On the other hand, genotype refers to the organism's entire set of genes, the sequences of DNA that code for specific traits, but are hidden within the cells, which can only be determined by genetic testing, not by simple observation.

Why are invasive species dangerous to the environment?
They pollute the environment.
They are voracious predators.
They threaten biodiversity.
They are nonrenewable.
Answer:
They threaten biodiversity.
Explanation:
bringing a species that is not native to the environment can can cause many problems because, most animals wont eat that species and they usually survive better than other species.
- for example the gypsy moth is an invasive species. moths eat trees and if no animals eats them, they threaten not only the tree but us humans that the trees provide oxygen to.
Invasive species are dangerous to the environment because they threaten biodiversity. Therefore, option C is correct.
What are invasive species and how do they affect the environment?A nonnative organism (disease, parasite, plant, or animal) that spreads or widens its range away from the location of its introduction and has the potential to affect the environment, the economy, or human health is referred to as an invasive species.
Native plants and animals may go extinct as a result of invasive species, which can also decrease biodiversity, compete with native species for scarce resources, and disrupt habitats.
Thus, invasive species are dangerous to the environment because they threaten biodiversity. Therefore, option C is correct.

What would happen if a dominant trait joined with the recessive trait? What is the end result? (Based off Gregor Mendel)
Answer:
When a dominant trait joins with the recessive trait, only the dominant trait will show when determining the organism's characteristics.
Explanation:
The dominant trait is "dominant" so it will mask the recessive trait. For example, brown eyes is a dominant trait for the color of someone's eye. Blue eyes is a recessive trait. If someone were to have both genes when they were born, they would have brown eyes because it masks the genes for blue eyes.
The graph shows the changing levels of hormones during menstruation and ovulation. What is the general trend for hormones after ovulation as an individual approaches menstruation?
A graph shows the changing levels of hormones during menstruation and ovulation. As an individual approaches menstruation, most of the hormone levels decrease.
Hormone levels generally decrease.
Hormone levels generally rise.
Hormone levels remain the same.
Hormone levels go in two different directions.
Answer:
Hormone levels generally decrease.
Explanation:
The graph showed that hormone levels after ovulation generally decrease.
The menstrual cycle of women generally have 3 phases which include:
The follicular phaseThe ovulatory phaseThe luteal phaseThe follicular phase is characterized by low levels of oestrogen and progesterone and a slightly high level of follicle stimulating hormone which ensures that follicles within the ovary develop.
The ovulatory phase is characterized by a surge in the luitenizing hormone (which stimulates the release of eggs) and follicle stimulating hormone with a decrease in the level of oestrogen and a gradual increase in the level of progesterone.
The luteal phase is characterized by a general decrease in the levels of luitenizing hormone and follicle stimulating hormone while oestrogen level may remain high.

Is the gene that causes hemophilia recessive or dominant? Use the image to explain your reasoning.
Answer:
It's a recessive trait. The carrier mother is heterozygous for the condition, but she does not have it. Boys who received one faulty gene are the only ones who suffer the condition.
Explanation:
plato <3
The gene that causes hemophilia is basically recessive linked with X chromosome of female.
What are recessive traits?A trait that is expressed only when the genotype is homozygous; a trait that is masked by other inherited traits but persists in a population among heterozygous genotypes.
A recessive gene is one whose effects are obscured when a dominant gene is present.
For each gene, every organism with DNA packed into chromosomes has two alleles, or forms of a gene: one inherited from their mother and one inherited from their father.
The image here shows that the if the father is hemophilic, then the daughter will be carrier and son will be normal.
But, if the mother is normal but carrier then, the son can have 50% probability to have hemophilia, but the daughter will be the carrier of the gene in 50% offspring.
Thus, it can be concluded that this is X-linked recessive trait.

Muscle cells in the human body can convert glucose into energy during moderate exercise. During intense exercise, however, the muscles become tired, lactic acid is produced, and pain can set in. Which statement best explains how muscle cell processes change as moderate exercise becomes more intense?
A. Oxygen becomes less available for respiration.
B. Carbon dioxide becomes more available for respiration.
C. Glucose is completely depleted during respiration.
D. ATP becomes depleted during respiration.
During the active and intense physical exercises, the speed of the glycolysis increases and lactate is produced. During an intense workout, the oxygen depletes.
What happens to the oxygen level?During the intense workout and exercise, the body muscles and cells cannot convert glucose molecules into energy and follow the pathway in the absence of oxygen resulting in the production of lactic acid.
Oxygen is the main input of the respiration process that becomes depleted and in the absence results in the formation of the lactic acid that provides muscle cells with the energy.
Therefore, option A. oxygen gets depleted and becomes less available for the respiratory process.
Learn more about lactic acid and oxygen here:
https://brainly.com/question/519398
Final answer:
As exercise intensity increases, oxygen becomes less available for aerobic respiration in muscle cells, prompting a shift to anaerobic metabolism, leading to lactic acid production and muscle fatigue.
Explanation:
The statement that best explains how muscle cell processes change as moderate exercise becomes more intense is: A. Oxygen becomes less available for respiration. During moderate exercise, muscles primarily use aerobic respiration to convert glucose into energy, utilizing oxygen to produce ATP, the energy currency of the cell. However, as exercise becomes more intense, the demand for ATP increases rapidly, outpacing the supply of oxygen. This leads to muscle cells relying more on anaerobic respiration, specifically glycolysis, which does not require oxygen but produces lactic acid as a byproduct. The accumulation of lactic acid contributes to muscle fatigue and can cause pain. Thus, the transition from moderate to intense exercise sees a shift from aerobic to anaerobic metabolism in muscle cells due to the reduced availability of oxygen.

Locate the data and observations collected in your lab guide. What are the key results? How would you best summarize the data to relate your findings?
Answer:
In a lab guide, the key results are those that support my working hypotheses or serve to reject these assumptions. Moreover, the key results may also be other discoveries that are important to understand the processes and/or mechanisms investigated in the experiment.
In my experience, the best way to summarize the key results is to create diagrams and illustrations that enables me to study relationships between different data
Although the Lab guide in the question is missing a general answer within the scope of your question is provided above
Key results in an experiment are either milestone results leading to the final result of an experiment or results obtained that might not be part of the experiment but very important to the success of the experiments. therefore results that leads to the acceptance or rejection of a hypothesis in an experiment is a key result. while
The best way to summarize data related to findings is the use of diagrams. ( graphical representation of the relationships between data contained in an experiment )
Hence we can conclude that use of diagrams is the best way to show the relationship between different data related to experimental findings while key results are results that justifies the acceptance of a hypothesis.

Would the same symptoms occur if the immune system were functioning properly ?
Answer:
The immune system can be broadly sorted into categories: innate immunity and adaptive immunity.Innate immunity is the immune system you're born with, and mainly consists of barriers on and in the body that keep foreign threats out, according to the National Library of Medicine (NLM). Components of innate immunity include skin, stomach acid, enzymes found in tears and skin oils, mucus and the cough reflex.
Explanation:
Answer: Rheumatoid arthritis is an autoimmune disorder. The immune system attacks the tissue between joints, causing the joints to distort,as seen in model 1. The joints between bones have less cartilage, as shown in Model 2. People who do not have the disease do not have these symptoms, because their immune system does not treat healthy tissue as a threat.
