A Colorblind male and a female that is h o m o z y g o u s for the normal allele have offspring. what percent of males would have normal vision, what percent of males would have c o l o r b l i n d n e s s, what percent of females would have normal vision, and what percent of females would have colorblindness?
Answer:
none of the males or females could be colorblind, assuming that this question is referring to x-linked recessive inheritance patterns.
Explanation:
if it is an x linked recessive trait, then the male's genotype is [tex]x^{b} y[/tex], with (b) representing colorblindness and (B) representing normal vision. the female, who is h o m o z y g ou s for normal vision, would have the genotype [tex]x^{B} x^{B}[/tex].
It would be impossible for the dad to pass on his colorblind gene to a son, because he can only pass a Y chromosome to the son. and a daughter would get the colorblind gene, but the normal gene donated by the mom would dominate it so the daughter could not actually be colorblind

Receptors placed in the different areas of the vestibular apparatus detect the types of equilibriums. 1) crista ampullaris, 2) utricle and saccule, 3) maculae, 4) semicircular canals, 5) cupula, 6) otoliths.
How is the vestibular apparatus composed?Three main areas compose the vestibular apparatus. These are the
utricle, saccule, and semicircular canals. What are the different types of equilibriums?The vestibular apparatus detects two types of equilibriums,
• The static equilibrium → Head and body position relative to gravity
• The dynamic equilibrium → Head and body position relative to rotational acceleration and deceleration.
These types of equilibriums are detected by receptors placed in different areas of the vestibular apparatus.
• Static equilibrium receptors are located in the macula of the utricle and saccule. They help to maintain balance.
• Dynamic equilibrium receptors are located in the semicircular canals. They provide information about the rotational movement.
The sensory hairs are located in the crista of the ampulla, at the base of each canal (crista ampullaris).
The sensory hairs are covered by a dense gelatinous material named cupula, the otolithic membrane.
The otoliths are calcium carbonate crystals placed over the cupula. Their movements depend on the head’s movements.

How does carbon enter the biotic components of the carbon cycle?
A) through the process of respiration
B)through the process of photosynthesis
C)through the combustion of fossil fuels
D) through decomposition of dead organisms
In the carbon cycle, plants take CO2 from the atmosphere and carry out photosynthesis by which they incorporate carbon into the biotic components of organic compounds.
What is the carbon cycle?It is a biogeochemical cycle that starts with carbon dioxide in the atmosphere, which is adsorbed together with the sun's energy in the photosynthesis process of plants.
Characteristics of the carbon cycleDuring the day, plants use the Sun's energy to convert CO2 from the atmosphere plus water into carbohydrates and oxygen, this process is photosynthesis.Therefore, we can conclude that the carbon cycle is a cycle that flows through the terrestrial ecosystem, through the photosynthesis of plants, by animals or decomposing organisms, and the oceans.

What can be used to measure primary productivity in an ecosystem?(1 point)
carbon dioxide consumption
water consumption
oxygen consumption
sugar consumption
Carbon dioxide consumption
Carbon dioxide consumption can be used to measure primary productivity in an ecosystem.
Primary productivity refers to the rate at which energy is converted to organic material by photosynthesis.Primary productivity can be calculated by analyzing the change in biomass of producer organisms.Primary productivity can also be calculated by analyzing the movement of carbon dioxide (consumption).
Primary productivity can also be estimated by analyzing the movement of carbon dioxide the movement of oxygen over time.

Bird diverges from lizard with the introduction of feathers. Rabbit and tiger diverge from lizard with the introduction of mammary glands. They are more closely related to salamanders than they are to birds. They are more evolved than salamanders and lizards. They evolved into a separate species due to the presence of lungs. They have jaws and lungs but lack claws or nails, feathers, and mammary glands.
Answer:
They are more closely related to tigers than they are to birds.
Explanation:
I just took the test.
The conclusion that can be drawn about trout from the diagram is :They are more closely related to salamanders than they are to birds. Birds claws, feathers, jaws and lungs. Trout has jaws only. Hence, they are entirely different from birds/
What are trouts ?Trout is kind of food fishes belonging to the family Salmonidae (order Salmoniformes) that are mostly restricted to freshwater, but certain species do migrate to the sea between spawning.
Trout typically inhabit chilly freshwater, frequently in riffles and deep pools, or amid submerged items. Like any other fishes, trout have jaws and they does not have lungs, claws or feathers. They respire through gills.
Higher animals like, rabbits, tigers, birds etc. consists of lungs and rabbits and tigers have Mamery glands. Salamanders does not have feathers or claws or like birds but has jaws and lungs. Hence, trouts are more alike to salamanders than birds.
