a human red blood cell is placed in a solution whose solute concentration is twice as great as the concentration of the cell cytoplasm. The cell membrane is selectively permeable allowing water but not the solutes to pass through. What will happen to the cell? a.) No change b.) the cell will shrivel because of osmosis c.) the cell will swell because of osmosis d.) the cell will shrivel because of active transport of water e.) the cell will swell because of active transport of water
Answer:
the cell will shrivel because of osmosis, moving to the region of higher concentration, and it shrivels due lost of water

below is a view at 1000x magnification of a gram stain of the cerebrospinal fluid. what type of white blood cell predominates in charlie’s csf?
The type of white blood cell that predominated in charlie's CSF is neutrophils.
Cerebrospinal fluid (CSF) is a transparent, colorless plasma ultrafiltrate with little protein and few cells. It is produced in the choroid plexus in the ventricular brain system.
The type of white blood cell that predominated in charlie's CSF is neutrophils. They are granular leucocytes, with active phagocytes. In the cytoplasm, there is the presence of neutral staining granules whose phagocytic activities are integral to subdue the invasion of pathogens.

According to the food chain shown, about how much energy from the grasshopper trophic level is transferred to the frog trophic level?
The amount of energy transferred to frog is 10% of the energy contained in grasshopper.
This is a representation of energy levels and distribution in a food chain in an Ecosystem. When a group of organism represent the same level in a food chain, in an ecosystem ,this is trophic level. Food chain represent a linear representation of nutrients and therefore energy distributions in an ecosystem.
Basically, in an ecosystem, there is always reduction in energy transfer from one trophic level to another by 10%. This is because, as the energy is transferred from the producer (green plants) to the primary consumer, the hopper, only 10% of the available energy will pass through to the hopper because 90% of the energy will be used by the green plants for metabolic and other physiologic activities. As this is transferred to the next trophic level, the Frog, this will be reduced (for the same reasons) so that 10% of the energy received by the grasshopper is transferred to the frog.
Practically, if 100,000Kcal of energy was obtained by hopper from the primary producer,10,000kcal(10%) of 100,000 will be transferred to frog.
This 10% occurs at each trophic levels.

As the troponin changes shape (due to binding calcium), it moves the ______ molecule to which it is attached, thus exposing the active sites on the G-actin molecules.
As the troponin changes shape (due to binding calcium), it moves the tropomysin molecule to which it is attached.
Once calcium binds to troponin and causes it to change it shape, it removes the tropomysin away from the binding site therefore effectively exposing the myosin binding sites.
This occurs during muscle contraction (movement) in the skeletal muscles.

Under the hypothesis of blending inheritance, what color(s) would the offspring of a black cat and a white cat be
Under the hypothesis of blending inheritance, the offspring of a black cat and a white cat would be GREY. This theory is not now accepted.
Blending inheritance is an erroneous theory from the 19th century that proposed that offspring inherit phenotypic traits as 'average values' observed for such traits in their parents.
Mendel's laws of heredity (i.e., the Law of Segregation and the Law of Independent Assortment) showed that blending inheritance is based on erroneous concepts.
Moreover, incomplete dominance is an inheritance pattern different from blending inheritance because incomplete dominance refers to the observation that in certain traits both gene variants or 'alleles' are expressed in heterozygous individuals.

1. Describe how chemical changes
are
different from physical changes.
Answer:
Physical changes only change the appearance of a substance, not its chemical composition. Chemical changes cause a substance to change into an entirely substance with a new chemical formula.
Explanation:
Answer:
In a physical change the appearance or form of the matter changes but the kind of matter in the substance does not. In a chemical change, the kind of matter changes, and at least one new substance with new properties is formed.
Explanation:
Physical changes are limited to changes that result in a difference in the display without changing the composition.

Two brothers have thick hair that grows over their faces and most of their bodies.
This human disorder, called Ambra's Syndrome, shows X-linked dominant inheritance. The
mother of the boys is also affected by Ambra's Syndrome, although her excessive hair growth
occurs in various, scattered patches on her skin rather than a continuous coverage like her sons.
What is the most likely explanation for the patchy expression of hairlessness on the mother's
skin?
The most likely explanation for the irregular expression of hairlessness on the mother's skin is codominance
Codominance is a biological term to refer to the hereditary pattern that is characterized by:
In the heterozygous state, there is no recessive allele, but both behave as dominant. Codominance is characterized by the manifestation of both characteristics as dominant, without mixing.According to the above, the irregular expression of the lack of hair in the mother is a manifestation of the codominance of the hair gene and the hairless gene that do not mix but are seen independently.
