Answer:
The genotype of a black male is XtY
Explanation:
Available data:
coat color is an X-linked trait with incomplete dominance.Yellow coat is caused by the allele XTBlack coat by the allele Xt.Tortoise coat is caused by the heterozygous conditionSo,
females genotypes females phenotype
XTXT → Yellow coat XtXt → Black coat XTXt → Tortoise coatmales genotype males phenotype
XTY → Yellow coat XtY → Black coatMales only carry one X chromosome, so they can only be either black - XtY- or yellow -XTY-.
Females are the only ones that can express the tortoise coat.
The correct way to represent the genotype of a male cat with a black coat - XtY
We know that,
In cats, coat color is an X-linked trait - it means it is influenced by the X allele onlyIn cats, coat color is shows incomplete dominance - it means if corresponding alleles present together they will show an intermediate coat color.the allele XT - Yellow coatthe allele Xt - black coatXTXt (heterozygous) - tortoise coat (incomplete dominance)In X linked traits heterozygous conditions are not possible in males as they have only one X allele and the other is Y allele.So,
Female cats genotype would be:
XTXT - female cat with yellow coatXTXt - female cat with a black coatXtXt - female cat with tortoise coatMale cats genotype:
1. XtY - black coat male cat
2. XTY - yellow coat male cat.
Thus, The correct way to represent the genotype of a male cat with a black coat - XtY

What do coral reefs and estuaries have in common?
Answer: hewo, there! your answer is below
stuaries are areas of water and shoreline where rivers meet the ocean or another large body of water, such as one of the Great Lakes. Organisms that live in estuaries must be adapted to these dynamic environments, where there are variations in water chemistry including salinity, as well as physical changes like the rise and fall of tides. Despite these challenges, estuaries are also very productive ecosystems. They receive nutrients from both bodies of water and can support a variety of life. Because of their access to food, water, and shipping routes, people often live near estuaries and can impact the health of the ecosystem.
Explanation: Here's some Info Below <3
shallow water, reef-building corals have a symbiotic relationship with photosynthetic algae called zooxanthellae, which live in their tissues. The coral provides a protected environment and the compounds zooxanthellae need for photosynthesis. In return, the algae produce carbohydrates that the coral uses for food, as well as oxygen. The algae also help the coral remove waste. Since both partners benefit from association, this type of symbiosis is called mutualism.
Deep-sea corals live in much deeper or colder oceanic waters and lack zooxanthellae. Unlike their shallow water relatives, which rely heavily on photosynthesis to produce food, deep sea corals take in plankton and organic matter for much of their energy needs.

At rest the lens of the eye will be more round when the ciliary muscles are contracted true or false
Answer:
True.
Explanation:
Yes, the lens of the eye will be more spherical when the ciliary muscles are contracted due to tension. When the relaxation occurs in the ciliary muscle , the zonular tension is increased, that causes the lens to be flatten and leads to decrease in optical power while on the other hand, when the ciliary muscle contracts, the tension in the equatorial zonular is increased which causes the central lens surface to become more rounded that leads to increases central optical power.

deltas
earthquakes
HELPPPPP PLZ NEED IT BY TODAY PLLZZZZZZ 10 PIONTS
Answer:
delta
Explanation:
deltas take time to cause changes in the earth's surface as it takes time for water to erode and change things. volcanoes takes minutes to burn and ruin anything in its path, and landslides destroys everything in its path as well immediately.
A rapid or fast change can be defined as one that occurs quickly within a short amount of time.
Among the given example of changes, the types of changes are as follows:
Landslides - It is a result of imperceptive downslope movement and can occur within 10 seconds.Volcanoes - The eruption of volcanoes takes only a few seconds.deltas - The slow and steady flow of rivers form deltas and may take up to thousands of years.Earthquakes - It occurs within a few seconds after the fault ruptures and the ground shakes.Thus, the change that is not rapid is the formation of deltas.

Explanation:
I did the science moon phases for this! I would explain if it showed the graph and everything.
Good luck with it!
The Moon's orbit, which completes one full spin in 27 days, 7 hours, and 43 minutes, is the source of this motion. It compels the Moon to move 12–13 degrees east every day. February 25, March 27, April 25, May 24 Thus option C is correct.
What is Full Moons?When the Moon fills the sky in a perfect circle, it is said to be full.
We can only view the portions of the Moon that are illuminated by other objects because the Moon doesn't create any visible light on its own.
This change causes Moonrise to occur every day around 50 minutes later and necessitates a slightly longer Earth rotation to bring the Moon into view.
Technically, the Moon's “fullness” lasts only a brief period of time.
Therefore, the Moon can appear to be full to the unaided eye for as long as three days.

Distinguish between an acid and alkaline slant?
Answer:
Acid slant: yellow, fermentation of glucose and lactose and/or sucrose. High concentration creates excessive acid formation
Alkaline slant: red, limited glucose in the medium and limited acid formation.
The pH of acids is less than 7. Alkalis have a pH more than 7 The pH of neutral substances is 7. If metal oxides are soluble in water, they are alkaline. Non-metal oxides are acidic, if soluble in water.
What are acids?An acid is a molecule or ion that can either donate a proton (Bronsted-Lowry acid) or form a covalent bond with an electron pair (Lewis acid). The proton donors, also known as Bronsted-Lowry acids, are the first type of acid.
Only dextrose fermentation produces an alkaline/acid (red slant/yellow butt) reaction.
The fermentation of dextrose, lactose, and/or sucrose is indicated by an acid/acid (yellow slant/yellow butt) reaction.
An alkaline/alkaline reaction occurs when as a result, carbohydrate fermentation does not occur.
The presence of red (alkaline) in the slant and butt indicates that the organism being tested is a nonfermenter.
The formation of hydrogen sulfide results in a black precipitate in the butt of the tube. The splitting and cracking of the medium indicates gas production.
Thus, these are the basic difference between acid and alkaline slant.

write out the pathway that a drop of blood takes, starting in the right ventricle. As you describe the path, include the names of the blood vessels and the valves, and indicate if the blood is oxygenated or deoxygenated g
Answer:
The correct answer is - Right atrium, right ventricle, pulmonary arteries, lungs, pulmonary veins, left atrium, left ventricle, aorta, arteries, arterioles, capillaries, venules, veins, vena cavae
Explanation:
Throughout the vascular system or cardiovascular system, the drop of deoxygenated blood moves through right atrium and right ventricle to the lungs within the pulmonary arteries. Then the oxygenated blood transfers via pulmonary veins t the left atrium of the heart that pumps the oxygenated to the rest of the body by the left ventricle through the aorta.
Arteries help in the flow of the systemic circulation then blood moves from arterioles to capillaries. The deoxygenated blood is returned through the veins to the heart that come to the superior and inferior vena cava and back to right atrium and cirlculation repeat again.
Which class of Lever is being described if you are standing on tiptoes and if: The Fulcrum is at the metatarsal and phalanges, which is at one end of this lever on the anterior side of the body. The Load is your body weight which is in the middle of this lever. The Effort is exerted by the gastrocnemius and soleus muscles at the calcaneal (Achilles') tendon on the other side of this lever on the posterior side of the body.
Answer:
Second class lever
Explanation:
A second class lever is when the resistance ( load/weight ) is placed in between the axis ( Fulcrum which is formed by the metatarsal and Phalanges ) and the force ( Achilles tendon ) that is applied to the lever. hence the class of lever being described is a second class lever
There are three classes of lever ( 1st class, 2nd class and third class ) but The most common lever found in Humans are the 3rd class levers. but standing on tiptoes by an individual is a perfect example of a 2nd class lever found in a Human.
The Load being the body weight being and in the middle of this lever is
referred to a the second class lever.
The second class lever has the load in between the effort (force) and the
fulcrum. A common example is the wheelbarrow which has the load in the
middle.
In this scenario, the load which is the body is between the
effort(gastrocnemius and soleus muscles) and the fulcrum is the phalanges
which is a characteristic of a second class lever.
