why is a soda exploding/fizzing a physical change?

Answers

Answer 1

Answer:The fizzing of soda is a physical change that involves the release of gaseous carbon dioxide. During fizzing of a soda, you can see bubbles of carbon dioxide in the soda rise to the top. A bottle of soda doesn't fizz when it is closed because the pressure is higher, and keeps the carbon dioxide dissolved in the liquid.

The first plants to move into the new bare ground after a wildfire are wildflowers or “weeds.” These fast-germinating, leafy herbaceous plants are also known as “forbs” or “ephemerals.” They quickly germinate, grow and produce a new crop of seeds.

Answer:

Pioneer species are established

Explanation:

A forest fire would represent the process of secondary succession.

In secondary succession, the first stage is the growth of pioneer species. The soil still remains, so no new soil needs to be made.

This rich soil allows for pioneer species to grow in the forest.

Who wants brainliest? Answer those 2 questions

Answers

Answer:

This type of natural selection occurs when there are selective pressures working against two extremes of a trait and therefore the intermediate or “middle” trait is selected for. If we look at a distribution of traits in the population, it is noticeable that a standard distribution is followed: Example:  For a plant, the plants that are very tall are exposed to more wind and are at risk of being blown over. The plants that are very short fail to get enough sunlight to prosper. Therefore, the plants that are a middle height between the two get both enough sunlight and protection from the wind.

This type of natural selection occurs when selective pressures are working in favour of one extreme of a trait. Therefore when looking at a distribution of traits in a population, a graph tends to lean more to one side: Example: Giraffes with the longest necks are able to reach more leaves to each. Selective pressures will work in the advantage of the longer neck giraffes and therefore the distribution of the trait within the population will shift towards the longer neck trait.

This type of natural selection occurs when selective pressures are working in favour of the two extremes and against the intermediate trait. This type of selection is not as common. When looking at a trait distribution, there are two higher peaks on both ends with a minimum in the middle as such: Example: An area that has black, white and grey bunnies contains both black and white rocks. Both the traits for white and black will be favored by natural selection since they both prove useful for camouflage. The intermediate trait of grey does not prove as useful and therefore selective pressures act against the trait.

Genes help to define who an individual is inside and out. In addition to visible traits like weight and eye color, psychological qualities such as personality traits, intelligence, risk of mental illness, and more have been linked to genetics.

Explanation:

This is what I could find.

1: overproduction, genetic variation, struggle to survive, and successful reproduction are 4 steps.

2: gene is a unit of heredity which is transferred from a parent to there kids(offspring). They relate to traits in people because if you’re born tall you got it from your mom/dad or their family traits.

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another. Why is this the case? (3 points)



a) Some membrane components are synthesized outside of the cell, while others are synthesized in the cytosol.


b) The two sides of a cell membrane face different environments and carry out different functions.


c) The molecular composition of the inner and outer layers of the cell membrane is determined by genes.


d) Proteins only function on the cytoplasmic side of the cell membrane, which results in asymmetry across the membrane.

Answers

Answer:

The protein, lipid, and carbohydrate compositions of the cytoplasmic and extracellular sides of membranes are different from one another , this happens because the two sides of a cell membrane face different environments and carry out different functions.

Explanation:

PROTEINS , LIPID AND CARBOHYDRATES , all are the components of the plasma membrane , located at different sites .

PROTEINS -: The main component of plasma membranes is proteins. Two key categories of membrane proteins are available: integral and peripheral. As their name implies, integral membrane proteins are incorporated into the membrane: they have at least one hydrophobic region that anchors them to the phospholipid bilayer's hydrophobic center. Others just stick partway through the membrane, while others extend from one side of the membrane to the other and on either side are exposed.

On the outside and inside surfaces of membranes, peripheral membrane proteins are found which are bound either to integral proteins or to phospholipids. Peripheral membrane proteins do not stick into the hydrophobic center of the membrane as opposed to integral membrane proteins, and appear to be more loosely bound.

LIPID -: Phospholipids, arranged in a bilayer, make up the plasma membrane 's essential cloth. Since they are amphipathic, they are well-suited for this function, meaning they have both hydrophilic and hydrophobic regions.

The hydrophilic or "water-loving" component of a phospholipid is its head, which includes a phosphate group that is negatively charged, as well as an additional small group that can also be charged or polar.

Its long, nonpolar fatty acid tails make up the hydrophobic, or "water-fearing," portion of a phospholipid. The tails of fatty acids can interact easily with other non-polar molecules, but interact poorly with water.

CARBOHYDRATES -: The main component of plasma membranes is carbohydrates. In general, they are located on the outer surface of the cells and are either bound to proteins (glycoproteins forming) or to lipids (glycolipids forming). These chains of carbohydrates can consist of 2-60 units of monosaccharide and can either be straight or branched.

Hence , the correct option is B.

the diagram shown represents a dihybrid cross between two pea plants heterozygous for both seed color and seed shape.

B. 1:3:3:9

D. 4:12


Answers

Answer:

1:3:3:9

Explanation:

There are 12 yellow seeds, from which 9 are smooth and 3 are rough.

There are 4 green seeds, from which 3 are smooth and only 1 is rough.

Both the appearance and color of the seeds is something you need to look out for when dealing with phenotypes.

The phenotypic ratio of this dihybrid cross will be 1:3:3:9.

What is phenotype?The term phenotype simply refers to a trait that may be observed. Pheno means observe  and is derived from the same root as "phenomenon." As a result, it's a sort of organism that can be seen, and it may relate to anything from a common characteristic like height or hair color to the presence or absence of disease.What is dihybrid cross?A mating experiment between two animals that are identically hybrid for two features is referred to as a dihybrid cross. A heterozygous organism is one that possesses two distinct alleles at the same genetic location, or locus.The cross between a homozygous pea plant with round yellow seeds and wrinkled green seeds is an example of a dihybrid cross.RRYY alleles are found in round yellow seeds, while rryy alleles are found in wrinkled green seeds.

Hence the correct option is B.

Why is there limited vegetation in the tundra?

Answers

Answer:

Frigid temperatures, etc.

Explanation

The tundra has very low temperatures and a layer of permafrost over the soil. It has characteristics similar to the desert and it also has a short summer and a long, freezing winter. Therefore, there are not many flora variations that can thrive in that biome.

Answer:

The tundra experiences little rainfall, which makes the soil devoid of nutrients. The soil is permafrost, or permanently frozen. Both of these factors make it difficult for plants to grow in the tundra.

Answers

Answer:

both ions are transported actively

Explanation:

If both ions are being transported against their concentration gradients, then they are both being transported by active transport, as it requires energy.

A co-transporter moves two substances across the membrane, one passively and one actively. But in this case neither ion is moved passively, so it cannot be considered a cotransporter

When two species are forced to interact in a particular environment, how would
relationships of competition, predation, and mutualism affect the two populations?

Answers

Answer:

Find the explanation below.

Explanation:

When two species find themselves in the same environment, the quest for survival would lead to interactions among themselves.

Competition would result when there are limited resources. For example, when Tigers and Lions who feed on the same prey exist together in an environment, a competitive relationship can result.

Predation is a sort of interaction where an organism feeds on a prey to survive. Here, the weaker animal/species stands the risk of being defeated in the battle for survival. For example, in some homes where cats and rats exist, the cats tend to prey on the rats.

Mutualism is a form of symbiotic relationship where the animals exist together in a cooperative manner. Most fungal species have been found to have a mutualistic relationship with the roots of plants. Each of these two is important to each other's survival.

What is ecosystem ?

An ecosystem is the unit of ecology, a structural and functional unit of where the living organisms dwell with each other and with their surrounding environment and the term was  coined by A.G.Tansley, an English botanist, in 1935.

The structure of an ecosystem can be up two types such as Biotic Components and Abiotic Components, both the components are interrelated  where the flow energy and components occur throughout the boundaries.

Biotic components belongs to all living components which can be classified into autotrophs, heterotrophs and saprotrophs. Autotrophs are the producers like plants which make food independently by photosynthesis.

The organisms that depend on other organisms for their food called as consumers or heterotrophs, it can be classified into primary consumers, secondary consumers and tertiary consumers.

Primary consumers are herbivores, Secondary consumers get energy from primary consumers can be either carnivores or omnivores. Tertiary consumers get energy from on secondary consumers.

Quaternary consumers prey on tertiary consumers, Decomposers include saprophytes such as fungi and bacteria depend on dead and decaying matter.
