How does disease affect blood pressure
Explanation:
The body has lots of mechanisms that can control the blood pressure, plus, changing the amount of blood the heart pumps, the diameter of the arteries, and volume of blood in the bloodstream. When a disease causes blood pressure to stay high, low, or in between, problems can arise.
Match the arteries and veins to their functions.
Answer: deoxygenated blood from lower parts of the body = veins from inferior vena cava
oxygenated blood to the rest of the body excluding lungs = arteries from aorta
oxygenated blood to cardiac muscles = arteries from coronary arteries
supplies deoxygenated blood from upper part of the body = veins from superior vena cava

Hitchhiker's thumb (H) is dominant to no hitchhiker's thumb (h). A woman who does not have hitchhiker's thumb marries a man who is heterozygous for hitchhiker's thumb. What is true of their offspring?
Answer:
There is a 50% chance the kids will have Hitchhiker's thumb
Explanation:
Because Hitchhiker's thumb is dominant and the woman doesn't have it it's safe to assume her genes for it are hh. In a punnet square it would look like
h h
H | Hh Hh
h | hh hh
If that makes any sense I hope it does
Point is, 2 of the 4 boxes would say Hh and the other two would have hh

Sleet is precipitation made of small particles of ice. How does sleet form?
Answer:
Sleet is pellets of ice that form when snow falls into a warm layer and melts into rain. The rain then falls into a freezing layer of air that is deep enough to refreeze the raindrops into pellets. Sometimes the snow does not completely melt and the partially melted snowflakes refreeze into snow pellets.:
hope this helps!
Answer:
There must be a layer of air near the ground whose temperature is below freezing, where water turns to ice. Above this layer of freezing air must be a layer of warmer air. As snow falls through the warm air, it melts or partially melts into raindrops. It forms sleet before it reaches the ground.

A geneticist collected a population of 100 peppered moths. 36 were dark (DD or Dd) and 64 were light (dd). The alleles present in each moth were determined. Out of the 200 alleles for this gene present in this population, the gene pool contained 40 dark D alleles and 160 light d alleles. What are the allele frequencies for the two alleles in this population?
A) D = 0.36; d = 0.64
B) D = 0.50; d = 0.50
C) D = 0.25; d = 0.75
D) D = 0.20; d = 0.80
Answer:
D) D = 0.20; d = 0.80
Explanation:
Ok, so first off, we know that the number of homozygous recessive individuals is 64. So 64/100 is the q^2 value. The q value is the square root of that: it is 0.8. Because p + q has to always equal 1, the p value is then 0.2, and the p^2 value 0.04.
So, we know that the heterozygotes had to be 0.16 of the population (1-0.8-0.04 = 0.16).
d has to equal 0.8 because it is the number of recessive alleles in the population, and they give you this too. D is 0.2.

In humans, B is the allele for brown eyes and b is the allele for blue eyes. Two brothers both have brown eyes, but one of them has both the B and b alleles while the other only has B alleles. Which statement is true about the brothers?
Answer:
B is the dominate trait, and b is the recessive trait. Putting them together (Bb), would still mean that the brother would have brown eyes, since Bb means that the dominant trait is shown
bb- recessive trait (blue eyes)
Bb - dominant trait (brown eyes)
BB- dominant trait (brown eyes)

The discovery that the moon is similar in composition to the outer portions of the earth most supports the
theory.
synchronous
capture
impact
co-formation
Answer:
It most suppoet tge impact theory.
Explanation:
The his impact theory or the big splash is one of the accepted theories of tge moon and it states that the moon or luna and explain the origin of the moon that a Mars sized object planetestimal collided with the the proto Earth and the ejecta debris joined together by gravitational force which is the moon and it's orbit the Earth. The moon have similar composition to the outer portion of the Earth.
Answer:
Impact Theory
Explanation:
"The Impact Theory has two advantages over other theories about the moon's origin. First, other theories cannot explain the differences in the composition of the earth and moon. . . If Earth and a Mars-sized object collided, their iron-rich cores most likely would have merged into the earth's core. The collision would eject dust primarily from the mantles of the two bodies. This would explain why the moon's composition is similar to the composition of Earth's mantle."
The co-formation theory is not supported by that discovery because its composition should have been the same. "Although the moon is similar in age to Earth, its composition is very different. Earth is 31% iron, with most of the iron contained in the earth's core. The moon is only 8-12% iron. This difference is hard to explain if the earth and moon formed from the same material."
Therefore, it is not the co-formation theory, it is the impact theory.

Losing 100 orangutans a week is an astonishing number. Within your lifetime they could become extinct in the wild because of human impact. We use palm sugar in many products consumed and other things. Do you feel that it could be said we have a parasitic relationship with orangutans? Defend your answer.
if the orangutans eat the fruits, basically their place of residence is their only means of obtaining and if the human continues to cut down trees and destroy forests, the fruits will be lost and the monkeys will starve and thus could become extinct.

At which point is crust neither created nor destroyed?
O island chain
O mid-ocean ridge
divergent boundary
O transform boundary
Answer:
transform boundary
Explanation:
At a transform boundary, crust is neither created nor destroyed. Therefore, option (D) is correct.
What is transform boundary?A transform boundary, also known as a conservative boundary or a strike-slip boundary, is a type of tectonic plate boundary where two plates slide horizontally past each other. Unlike convergent boundaries (where plates collide) or divergent boundaries (where plates move apart), transform boundaries involve plates moving alongside each other in opposite directions or in the same direction but at different speeds.
The movement occurs along a fault line, known as a transform fault. Transform boundaries are characterized by intense seismic activity, resulting in earthquakes. They can also cause the formation of prominent landforms, such as transform faults, fracture zones, and offset rivers or valleys. Examples of transform boundaries include the San Andreas Fault in California, which separates the North American and Pacific plates, and the Alpine Fault in New Zealand, separating the Pacific and Australian plates.

Jacque is hiking in the mountains and sees a very large and colorful rock layer. It looks different than the surrounding rock layers. What is the best way for Jacque to investigate what the environment was like when this rock layer was deposited?
Jacque could measure the height of the rock layer.
Jacque could check if the rock layer has fossils in it.
Jacque could look at the color of the surrounding rock layers.
Jacque could chip off a chunk of rock from the rock layer and smell it.
Answer:
Check if the rock layer has fossils in it.
Explanation:
The rock layer from the inside out and the fossils will tell you how old the rock is.
Jacque could check if the rock layer has fossils in it, as the presence and types of fossils can often provide clues about the environment in which they were formed.
What can a rock layer tell about the environment?To investigate what the environment was like when a rock layer was deposited, there are several approaches that can be taken:
Look for clues in the rock layer itself: The rock layer itself can often provide clues about the environment in which it was formed. For example, the presence of certain minerals or fossil types can indicate the presence of specific conditions, such as warm or cold temperatures, or a marine or terrestrial environment.
Examine the surrounding rock layers: The rock layers above and below the rock layer of interest can provide additional context and clues about the environment. For example, if the surrounding layers are sedimentary rocks, such as sandstone or shale, it may indicate that the area was once covered by water.
Use rock dating techniques: As mentioned earlier, techniques like radiometric dating and relative dating can help determine the age of a rock layer and provide insight into the environment that existed at the time it was formed.
Conduct additional analyses: Depending on the type of rock and the questions being asked, it may be possible to conduct more detailed analyses, such as chemical or isotopic analyses, to gather further information about the conditions under which the rock formed.
Consider the current location of the rock layer: The current location of the rock layer can also provide clues about the environment in which it was formed. For example, if the rock layer is found in a mountain range, it may have formed in a tectonically active area, while a rock layer found in a flat, low-lying area may have formed in a more stable environment.
