How can heart disease affect a persons health
Answer:
Effects of CHD
Explanation:
With less blood flow, your heart doesn't get the oxygen it needs, and that can cause chest pain, called angina, especially when you exercise or do heavy labor It also can affect how well your heart pumps and make the rest of your body short on oxygen, too.

With only two foods available, natural selection has favored Flock which has grown the most in the
first three generations. Meanwhile, Flock Mhas declined the most because its beak was the least
successful phenotype for the food available.
( it’s Y and X)
Answer:
IT'S Y AND X
Explanation:
The question says so at the end :)
Flock X declines the most while natural selection has favored Flock Y the most. Hence, X and Y are correct.
What is natural selection?The process through which organisms adapt and change according to their surrounding is called natural selection. This theory was given by Charles Darwin. Individuals in a habitat are naturally different from each other. Some individuals have better traits to survive.
According to this theory, only those organisms will survive, which can change as their environment change, and can adapt. For example, the evolution of the long neck of giraffes to feed on leaves.
Flock Y has a strong beak for feeding due to which their chances of survival are maximum. While Flock X have a weak beak for feeding due to which their chances of survival are minimal. Therefore, X and Y are correct.

Tickleback evolution lab final quiz 1. how did some ancestral sea-run stickleback populations come to live exclusively in fresh water? these populations swam to freshwater lakes to spawn and then never returned to the ocean because there were fewer predators in lakes. they became trapped in lakes that formed at the end of the last ice age. they don't actually live exclusively in fresh water; they only live in fresh water at certain stages in their lives. they developed traits that made them better adapted to fresh water and, as a result, had to move to a freshwater environment to survive.
Answer:
The correct answer is "some stickleback populations come to live exclusively in fresh water they became trapped in lakes that formed at the end of the last ice age".
Explanation:
There are different types of speciation. Allopatric speciation consists of the geographic separation of a continuous genetic background so that it can give place to two or more new geographically isolated populations. Some barriers might impede the genetic interchange or genetic flux, making a place to two new populations that are separated and can not get together to mate anymore. Glaciation is one of the most important drivers of speciation and production of different phylogeographic structures by vicariance. Glacials originate isolated gene-pools that accumulate differences that end in reproductive isolation. Melting of the ice also generated divergence and speciation, as land appearance acted as a barrier for some populations.
During the last glaciation, stickleback fishes were able to reach certain new places or areas that provided better conditions to inhabit. There were fewer predators and more available food sources that made these new areas to be a better choice. These new grounds were lakes and were the product of ice melting. But at a certain point, as ice melting increased, the land started to show up again and became a barrier for this species. Animals that were living in lakes could not go back to the sea, they were trapped so they had to adapt to living exclusively in lakes. This species diverged and suffered speciation.

Explanation:
A skeleton is found with smooth brow ridges, sub pubic angle of 101
degrees, a small mastoid process, and narrow hip bones. Is the skeleton a
biological male or female? Justify your answer with an explanation on
how you came to your conclusion. *
Your answer
Answer:
This is a woman's skeleton.
Explanation:
Although the skeleton shown in the question above has narrow bones in the hips and women, in general, have wider bones in the hips than men, we can say that the skeleton mentioned above belongs to a biological woman. This is because we know that this skeleton has a 101 degree subpubic angle, however, the subpubic angle in male pelves varies from 70 to 75 degrees.

How has shark skin been used to inspired materials that slide faster through the water?
Answer:
Shark skin has been used by many cultures as sandpaper. It's kept shipmates safe in slippery-when-wet conditions. Swimsuits modeled on shark skin are said by Speedo to reduce drag by up to 4 percent. Now, research by two separate groups could lead to synthetic shark skin that would make ships and submarines faster and less expensive to operate.

When population grows past the ecosystem’s carrying capacity, what happens to the population?
A. Continues to grow
B. The population starts to die off to return to carrying capacity
C. The population will go extinct due to lack of resources
D. The population grows, then finds a new carrying capacity.
Answer:B animals will die since there arent enough resources for everyone until there is enough for the remaining population to use
When Population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).
The carrying capacity refers to the maximum number of individuals of a population that can be supported by particular environmental conditions.Carrying capacity depends on both biotic factors (e.g., presence of predators, food availability, etc.) and abiotic factors (e.g., water availability, living space, etc).When a population passes its carrying capacity, then the environment becomes unsuitable for the individuals of that population to survive.In conclusion, when population growth past the ecosystem’s carrying capacity, then the population starts to die off to return to carrying capacity (Option B).

Do you think that the frequency of echolocation sounds from bottlenose dolphins will be higher or lower than that of the blue whale call described in activity one?
Answer:
The frequency is higher in case of echolocation sounds produced by Bottlenose dolphins. It falls in the range 40,000 Hz to 130,000 Hz, while the calls made by blue whales lies in the range of 30 Hz to 8,000 Hz.
However, the blue whale calls last a lot longer than the echolocation sounds made by the dolphins. A typical blue whale call is between 10 to 30 seconds long, while the dolphin's click is only 50 to 128 microseconds long.

31. Briefly describe how igneous rocks form. How do both of the two main subcategories form?
32. Briefly describe how sedimentary rocks form. How do both of the two main subcategories form?
33. Briefly describe how metamorphic rocks form. How do both of the two main subcategories form?
Answer: 31, Igneous rocks are formed from lava or magma. Magma is molten rock that is underground and lava is molten rock that erupts out on the surface. The two main types of igneous rocks are plutonic rocks and volcanic rocks. Plutonic rocks are formed when magma cools and solidifies underground
32, Sedimentary rocks can be organized into two categories. The first is detrital rock, which comes from the erosion and accumulation of rock fragments, sediment, or other materials—categorized in total as detritus, or debris. The other is chemical rock, produced from the dissolution and precipitation of minerals
33, Rocks are formed on Earth as igneous, sedimentary, or metamorphic rocks. metamorphic rocks form from heat and pressure changing the original or parent rock into a completely new rock.
