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.

Answer: Yes, yes it does

Answer:

No, it will just make it harder.

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.

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

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.

Apes were basically monkeys. They walk on their hands and feet but crouched. There's a bunch of theories saying that humans evolved from apes. As apes evolved, they started walking upright.

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.

No, not absorb nitrogen.

yes. plants absorb nitrogen through soil

Answer:

The correct answer is - Biotic factors are any living factors and abiotic factors are anything non-living in an ecosystem.

Explanation:

An ecosystem consists of all living organisms, non-living organisms that are present in a physical environment in a particular geographical area. The physical environment consists of several factors such as landscape, pH, climate, salinity, and other factors that represent abiotic factors.

Any living organism present in an ecosystem is biotic factor Examples of biotic factors include are mammals, birds, trees, microbes, grasses, fish, bacteria, and many more.

Answer:

Bats have few natural predators -- disease is one of the biggest threat. Owls, hawks and snakes eat bats, but that’s nothing compared to the millions of bats dying from White-Nose Syndrome. The disease -- named for a white fungus on the muzzle and wings of bats -- affects hibernating bats and has been detected in 33 states and seven Canadian provinces. More than 6.5 million bats have died so far from White-Nose Syndrome. Scientists are working to understand the disease. You can help -- avoid places where bats are hibernating, and if you do go underground, decontaminate your clothing, footwear and gear.

Explanation:

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.

Answer:

The nature of amino acids can vary they can be acidic, alkaline, or neutral based on the functional group attached to their side-chain. The functional group of the amino acids determines the property of the hydro loving or phobic nature of particular amino acids. Interaction of different biomolecules depends on their affinities with one another such as hydrogen bonds, ionic bonds, van der Waals interaction based on structural and fundamental unit or monomer of the biomolecule.

Based on the given explanation, we can say that if there is a modification in the sequence of the building block amino acid of the FXR1 protein, might lead to a decrease in affinity to bind to the RNA by changing in the binding domain of this protein. There might be a complete structural change such that it can no longer interact with RNA.

Amino acids are grouped on the basis of their side chains.

Amino acids are categorized on the basis of their side chain attachment. All the amino acids has a specific side chain which is known as an R group. This R group is also attached to the α carbon. The R groups consist of shapes, sizes, charges, and reactivities. This allows all amino acids to be grouped or categorized on the basis of their chemical properties of their side chains.

If there is a change occur in the sequence of the building block amino acid of the FXR1 protein, it might lead to a decrease of binding to the RNA. There might be a complete change in the structure which leads no more attachment with RNA so we can conclude that amino acids are grouped on the basis of their side chains.

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.
