so if you look up things that can cause an asthma attack it will also show that viruses and bacteria are a cause. with asthma you lungs could already be inflamed as well as your air way wich makes it harder to breath. when you have c-19 it will inflame your lungs even more so it makes it even harder to breath given an asthma attack. more asthma attack now are probably caused by c-19 because it is all over the place and the percent of asthma attack by virus has dramatically increased.

Answers

C - Creativity born from interactions with nature

The one that is not an example of an ecosystem service is creativity born from interactions with nature. The correct option is c.

What is an ecosystem?

An ecosystem is a geographical area in which plants, animals, and other species, as well as weather and scenery, coexist to produce a life bubble. Ecosystems comprise both biotic (living) and abiotic (nonliving) components.

Plants, animals, and other species are examples of biotic factors. A marine ecosystem, for example, contains 32% of the world's producers because water covers three-thirds of the earth's surface and provides a natural habitat for a diverse range of small and large living species and plants.

Therefore, the correct option is c. creativity born from interactions with nature.

How would the Earth's climate change if its obliquity shifted from 23.4° to 0°, and all other factors remained the same?

A-Global warming would increase rapidly.
B-It would shift the Earth into a global ice age.
C-The seasonal changes would be more extreme.
D-There would be no seasons.

Answers

Answer:

There would be no seasons.

Explanation:

The tilt of the Earth's axis is what causes seasons. Throughout the year, different parts of Earth receive the Sun's most direct rays. So, when the North Pole tilts toward the Sun, it's summer in the Northern Hemisphere. And when the South Pole tilts toward the Sun, it's winter in the Northern Hemisphere. If there was no tilt, the rays hitting the Earth would have minimal changes, meaning no seasons.

4. Many of your body’s responses operate off of either negative or positive feedback loops. When you are cold, you shiver. Explain why that happens.

Answers

Answer:

The tendency to maintain a stable, relatively constant internal environment is called homeostasis. The body maintains homeostasis for many factors in addition to temperature. For instance, the concentration of various ions in your blood must be kept steady, along with pH and the concentration of glucose. If these values get too high or low, you can end up getting very sick.

Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature. For instance, the stomach maintains a pH that's different from that of surrounding organs, and each individual cell maintains ion concentrations different from those of the surrounding fluid. Maintaining homeostasis at each level is key to maintaining the body's overall function.

Explanation:

shivering burns fat to help keep one warm

Homeostasis typically involves negative feedback loops that counteract changes of various properties from their target values, known as set points. In contrast to negative feedback loops, positive feedback loops amplify their initiating stimuli, in other words, they move the system away from its starting state.

Answer:

Geocentric Model

Earth is at the center

Includes five planets.

The orbits of the planets are circular,

Heliocentric Model

The Sun is at the center of the solar system.

The orbits of the planets are elliptical

Includes eight planets.

The solar system

Explanation:

The main difference between the heliocentrical and geocentrical model is that in the first one, the Sun is in the center and the planets are around it, while in the second model, the Earth is in the center and the Sun, the moon, and the planets are around it.

Also, the geocentrical model stated that there were five planets, Mercury, Venus, Mars, Jupiter, and Saturn. These planets had circular orbits. In other words, they have a circular motion around the Earth, and this one was still in the center of the system.

In the heliocentric model, there are eight planets, Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune, and they all rotate in elliptical orbits around the Sun. The Heliocentric model is also called the solar system since its central star is the Sun, and the planets are around it.

Ecological interactions can be categorized as competition, exploitation, or positive. Describe the types of interactions that fall into these categories, and provide an example of each type of interaction.

Answers

Answer:

Competition is an interaction between organisms or species in which both the organisms or species are harmed. Limited supply of at least one resource used by both can be a factor. This example is if two lions get into a fight and they end up hurting each other.

Exploitation competition occurs when individuals interact indirectly as they compete for common resources, like territory, prey or food. An example of this is when people are farming and they are trying to get the best food available but someone else might have already gotten it.

Commensalism is a positive type of ecological interaction between two species in an ecosystem. In commensalism, the association occurs between members of two different species where one species is benefited the other is neither benefited nor harmed. An example of this is tree frogs who use trees as protection.

EOC Biology STAAR Test Prep
In humans blood type is determined by the A, B, and O alleles. The A and B alleles are codiminant to each other and dominant over the O allele. An individual with the AO genotype and an individual with the BO genotype can produce offspring with which of the following phenotypes.
O only
A or B only
A, B or O only
A, B, AB, or O
Please explain, also this is not a test its a test PREP

Answers

Answer:

D. A, B, AB, or O

Explanation:

We can start by visualizing all the possible genotypes of the offspring by drawing a Punnett square, which is a visual representation of the different possible combinations of alleles:

Individual 1 = AO, Individual 2 = BO

     A   O

B  AB  BO

O  AO  OO

Here we can see that there are 4 possible genotypes: AB, BO, AO and OO based on the alleles of the parents. Now we can match the genotypes to phenotypes to answer the question:

A and B are codominant, meaning that both will be expressed equally if both are present. Therefore the genotype AB will result in an AB phenotype.

Next, since A and B are both dominant over O, they are the alleles that will be expressed in the phenotype if paired with an O. This means that the genotype AO will result in an A phenotype, and likewise, genotype BO will result in phenotype B.

Finally in the genotype OO, although O is a recessive allele, there are no dominant alleles here to mask them, therefore O is expressed in the phenotype.

Hence, from the genotypes AO and BO, the possible offspring genotypes are AB, BO, AO and OO, translating to the possible phenotypes: A, B, AB or O.

In griffins, the allele for black feathers (B) is dominant over silver feathers (b) which are recessive. Two black griffins are crossed and have a silver offspring. What is the genotype of the parents?

Answers

Answer:

The correct answer is - Bb and Bb.

Explanation:

In this case, there are two traits decided by the black "B" allele that is dominant over "b" which is silver. In this case the cross between two black feather birds and the there would be genotype:

BB and BB or Bb and Bb or Bb and BB

1.  In first case, and the third case, there is no or only one allele for the silver trait so the correct answer would be - Bb and Bb

    B      b

B  Bb     Bb

b   Bb    bb

thus, the correct answer is - bb which is silver feather.

the problem of people consuming too many fossil fuels to meet their transportation needs.
Which of the following behaviors could further refine this solution?
A. People can drive hybrid cars instead of using more conservative tecnics.
B. People can drive separate hybrid cars instead of carpooling
C. People can use additional conservation tactics, like sometimes bicycling
D. People can drive hybrid cars more often than they need to

Answers

Answer:

C. People can use additional conservation tactics, like sometimes bicycling

Explanation:

According to this question, cars called HYBRID cars are said to have the ability to switch back and forth between gasoline power and electric power in a way that reduces fuel use. This solves the problem of buying excessive transport fuel.

Asides the hybrid car, one can also use a more conservative approach, which is bicycling. Hence, the use of additional conservation tactics, like sometimes bicycling.
