A phase diagram assumes pressure is kept constant.
Answer: choice three
Answer:
pressure
Explanation:
The phase diagram is a graph used to indicate the temperature and pressure conditions necessary to obtain a substance in a specific physical state (solid, liquid or gas). In this type of diagram, pressure is a factor that is kept constant.
The x (horizontal) axis contains the temperature values, and the y (vertical) axis contains the pressure values. In addition, there are three curves connected to a single point (called a triple point), dividing the graph into three well-defined areas, as we can see in the diagram shown above.
In addition to indicating the conditions for the substance to be in a specific physical state, the phase diagram indicates the conditions for any change in physical state to occur.

which sentence describes a possible impact of early hunter – gatherer societies on the environment?
a. cultivating too many plants drained the land of water.
b. introducing non-native species led to the extinction of some plants.
c. overhunting led to the extinction of large herbivores species.
d. reliance on fossil fuels polluted air, water, and land.
Answer:
Hi,
The correct answer is option (C) Overhunting led to the extinction of large herbivores species
Explanation:
Herbivores are those animal species that eat plants only.Hunters and gatherers depended on their hunting skills to obtain meat as a source of protein/food for their families.Most of the animals that were hunted were herbivores.Overhunting reduced the number of these species because the process was not controlled thus there was no time for the animals to increase in numbers in the natural process
Best of Luck!
Answer:
c
Explanation:
Choose ALL the answers that apply.
Invasive species:
A) Can increase competition
B) Help prevent extinction
C) Reduce disease in a population
D) Are not native to the environment
Answer:
I think that the answers are A and D.
For option A, we can come to the conclusion by thinking about the effects of invasive species. For example, when an invasive species appears in a specific environment and unfortunately feed on the same kind of plant as the native species, it will lead to the fact that they have to compete more in order to survive.
For option B, we can clearly see that it's wrong. From the point above, we can also predict that there is a high chance the invasive species will win the competition, resulting in the decrease population of the native specices that couldn't compete.
For option C, it is also impossible, instead the opposite is more likely to happen, because as we know, the native species, after a long period of evolution, became almost perfectly adapted to the environment, the appearance of invasive species may help the diseases that the native species weren't immune to spread faster, decreasing the population.
And I guess option D is obviously correct, no need to explain.

Plant roots can be fibrous or a taproot. When there is not enough water in
the environment some plants send their taproot further down into the soil in
search for water, while some with fibrous roots increase the density of their
root systems. What does this demonstrate?
OA) genetic mutation induced by the environment
OB) differentiation of vascular tissue in plants
OC) structural response to the environment
OD) alternation of generations in plants
Answer: i beleive you answer would be D hope this helps :)
Answer:
The best response to this question: What does this demonstrates, regarding two different types of plants, one with a taproot system and the other with a fibrous root system, who alter their aleady existing root system in order to respond to the changes in their environment, would be: C: structural response to the environment.
Explanation:
When talking about plants, and their roots, there are two great categories: the dicot plants, whose root system is known as a taproot, and the monocots, whose root system is fibrous. Each of these systems is separate and particular to each type of plants. They do not combine, and they are unique to each of the categories of plants (dicots, and monocots). However, according to the question, the plants are encountering a climate change, and water has become scarcer. In response to this change, each of the plants, the one with the taproot, and the one with the fibrous root, respond structurally by either enlarging their root further into the soil (taproot), or by sprouting further filaments in the original root system (fibrous root). This, then, shows a structural change and it can happen in plants when environmental changes, not necessarily constant, happen. The plant will only alter its genetic makeup if the changes in environment are continuous and they need deeper changes in the plant, in order to survive.

why do the more complex sugar disaccharides store more energy than monosaccharides
Answer: Because Disaccharides have more chemical bonds
Explanation:
Answer: Because they have more bonds in them
Explanation:
More complex sugars have more bonds available that can be broken down into more simpler form.
When more complex carbohydrates are broken down into simpler carbohydrates then energy is released from the breaking of complex bonds into simpler form.
This is the reason why disaccharides have more energy as compared to that of monosaccharides.

Hummingbirds drink nectar from flowers robins eat plant seeds what does this reduce : a. Interspecific competition , be intraspecific competition ,c. cooperation ,d.mutualism
Answer:
Interspecific competition
Explanation:
Hummingbirds and robins are different species, so it is interspecific competition
Answer: a. Interspecific competition
Explanation:
The hummingbird drink the nectar from the flowers and robins eat plant seeds is the example of reduction of interspecific competition. The ecological niche of both of the species is different. An ecological niche can be define as the functional role an organism plays in an ecosystem.
In an interspecific competition, the individuals of distinct species compete for the same resource. This will lead to the extinction of any one of the species or decline in the members of the either of the species.
As the species of hummingbird is dependent upon the nectar and the robins are dependent upon the seeds as food therefore their will not be any interspecific competition among these species.

When a solvent equally disperses throughout a solution, what type of transport is this?
A. Facilitated diffusion
B. Active transport
C. Osmosis
D. Diffusion
The correct answer to the question is D. Diffusion, which is the process by which solutes spread from an area of higher concentration to an area of lower concentration until equilibrium is reached, without the need for external energy.
When a solvent equally disperses throughout a solution without the need for external energy and without the help of transport proteins, this process is known as diffusion. Diffusion is the movement of solute molecules from an area of higher concentration to an area of lower concentration until the concentrations are equal on both sides of the membrane. This process does not require energy, making it a form of passive transport. Facilitated diffusion, on the other hand, involves transport proteins but is still considered passive transport as it moves solutes down their concentration gradient. Therefore, the correct answer is D. Diffusion.
A mouse with curled whiskers migrates from one forest community to another. She mates with other mice in the new community and passes the gene for curled whiskers to her offspring. This is an example of _____.
genetic drift
mutation
gene flow
natural selection
Answer:
Option C: Gene flow
Explanation:
Gene flow is the transfer of genetic variation from one population to another. It is the movement of genes from one population to another population. If the rate of gene flow is high enough, then two populations are considered to have equivalent allele frequencies.
Sometimes gene pools within populations can change because individuals leave that population or new individuals come in. Like water flowing in a river, genes can also 'flow' from one place to another.
For example:
A honey bee carrying pollen from one flower population to another.A caribou from one herd mating with members of another herd A blonde haired, blue-eyed family from Sweden moves to some Asian country where the children grow up, marry and produce offspring who now have the blonde-haired, blue-eyed alleles.Answer:

How are food chains and food webs related
Answer:
A food web consists of many food chains. A food chain only follows just one path as animals find food. eg: A hawk eats a snake, which has eaten a frog, which has eaten a grasshopper, which has eaten grass. A food web shows the many different paths plants and animals are connected.
Explanation:
Answer:
The food webs is formed by several food chains. This is the relationship between the two systems.
Explanation:
Food web is a set of interconnected food chains. The food web represents the many relationships between organisms in an ecosystem.
Ecosystem is the place or environment in which mutual relations between all beings that inhabit it develop. The same living being inserted in an ecosystem can belong to different food chains, playing different roles.
It can feed another living being or serve as food. In the process, the food chains end up meeting and forming a food web.
Food chain is a sequence of living beings that are divided into producers, consumers and decomposers. In the food sequence, living beings feed on those who go before them in the chain, to then be eaten by those who are following, according to the hierarchy.

Thank you!! Will give Brainliest if possible!
Answer:
Sorry I couldn't draw the punnett squares. Also I'm not sure if you need to reduce the ratios or change them into percents but hopefully this helps
1. S s
S SS Ss
s Ss ss
Genotypic ratio- 1 SS: 2 Ss: 1 ss
Phenotypic ratio- 3 short haired: 1 long haired
2. W w
w Ww ww
w Ww ww
Genotypic ratio- 2 Ww: 2 ww
Phenotypic ratio- 2 white wool: 2 black wool
3. G g
G GG Gg
G GG Gg
Genotypic ratio- 2 GG: 2 Gg
Phenotypic ratio- 4 green pods: 0 yellow pods
4. B B
b Bb Bb
b Bb Bb
Genotypic ratio- 4 Bb: 0 bb: 0 BB
Phenotypic ratio- 4 brown seeds: 0 white seeds
Using Punnett squares for various genetic traits in animals and plants, you can predict the genotypic and phenotypic ratios of the offspring. In each case, allele dominance determines the phenotypic outcome.
Explanation:Let's complete the Punnett squares for the given genetic problems to determine the genotypic and phenotypic ratios of the offspring.
1. Short Hair (S) vs Long Hair (s) in Rabbits:
Heterozygous short-haired rabbits have a genotype of Ss. When we cross two Ss rabbits, the Punnett square yields the following genotypes: SS, Ss, Ss and ss. This results in a genotypic ratio of 1 SS : 2 Ss : 1 ss. Because the short hair gene (S) is dominant, the phenotypic ratio will be 3 short-haired to 1 long-haired.
2. White Wool (W) vs Black Wool (w) in Sheep:
When we cross a heterozygous white wool sheep (Ww) with a black wool sheep (ww), the Punnett square yields genotypes: Ww and ww. Therefore, the genotypic ratio is 1 Ww : 1 ww. Since white wool is dominant, the phenotypic ratio is 1 white : 1 black.
3. Green Pod (G) vs Yellow Pod (g) in Plants:
Your cross is between a heterozygous green pod plant (Gg) and a homozygous green pod plant (GG). This yields genotypes: GG and Gg, hence a genotypic ratio of 1 GG : 1 Gg. As green is dominant, all offspring should be green in phenotype.
4. Brown Seeds (B) vs White Seeds (b) in Plants:
The cross is between a homozygous brown seed plant (BB) and a white seed plant (bb), resulting in all offspring being heterozygous (Bb). Therefore, the genotypic ratio is 1 Bb, and as brown is dominant, all offspring will have brown seeds.
