Answer:c
Explanation: The plant is responding to external stimuli by growing toward light like our eyes adjusting to the light in the dark......................
The correct answer is option c i.e. responding to external stimuli (phototropism).
Plants have a variety of developmental, physiological, and growth responses to light—sometimes only to particular wavelengths of light.
what is phototropism?
Phototropism is one of the many plant tropisms or movements which respond to external stimuli.
Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism.
Phototropism is a directional response that allows plants to grow towards, or in some cases away from, a source of light.
Photoperiodism is the regulation of physiology or development in response to day length. Photoperiodism allows some plant species to flower—switch to reproductive mode—only at certain times of the year.
hence , a plant growing towards a light source is an example of phototropism.

I believe the answer is parasitism. The cuckoo bird uses sneaky tactics to trick the warbler into doing the parenting for them
Answer:
I believe the answer is parasitism
Explanation:
it makes the most sense within this scenario. The cuckoo bird invades another oragnism's way of life, harms the other eggs in the process, and lives off of the shelter and nurtrients that would have been the baby warblers given by the warbler mom.
mutualism: symbiosis that is beneficial to both organisms involved
commensalism:an association between two organisms in which one benefits and the other derives neither benefit nor harm.
parasitism:the practice of living as a parasite in or on another organism.
3.Whenever the surfaces in contact tend to move or move with respect to each other, the force of friction comes into playRequired to answer. Single choice.
Answer:
The correct answer is - Friction occurs irrespective of the state of the matter.
Explanation:
Friction is the force that takes place when there are two different surfaces slide or moves across one another and causes a resistance between surfaces. The friction always takes place opposite direction to the other surface direction of moving.
Pushing a book on a table, pulling a heavy cart on road all are examples of friction. The friction that occurs in liquids and gases is called fluid friction. Thus, the friction takes place irrespective of the state of the matter.

Explain the water cycle in one paragraph.
Answer:
The water Cycle
Explanation:
The water cycle or hydrologic is a continuous cycle where water evaporates, travels into the air and becomes part of a cloud, falls down to earth as precipitation, and then evaporates again. This repeats again and again in a never-ending cycle. Water keeps moving and changing from a solid to a liquid to a gas, over and over again.
Precipitation creates runoff that travels over the ground surface and helps to fill lakes and rivers. It also percolates or moves downward through openings in the soil to replenish aquifers under the ground. Some places receive more precipitation than others do. These areas are usually close to oceans or large bodies of water that allow more water to evaporate and form clouds. Other areas receive less precipitation. Often these areas are far from water or near mountains. As clouds move up and over mountains, the water vapor condenses to form precipitation and freezes. Snow falls on the peaks.

Explanation:
in humans, dimples are dominant to no dimples. cross a woman with no dimples with a man who is heterozygous for dimples. determine the phenotypic and genotypic ratio of their offspring. show a punnett square to support your answer
Genotype: 50% Aa and 50% aa
Phenotype: 50% Dimples and 50% no dimples
Explanation: Using a punnet square, we can figure out that the mother is recessive and the father is heterozygous. Putting the mother at the top of the square and the father on the side, you end up with the results above by crossing each square with the corresponding letters. It's okay if the letters end up backwards. Just be sure to face them the right direction, capitals being first once you finish.

Question 9
How do animals get nitrogen that is stored in the soil?
O A) Animals do not take in the nitrogen stored in the soil.
O B) Bacteria change the nitrogen into a gas that the animals breathe.
OC) Plants ab orb the nitrogen from the soil and animals can eat the plants.
O D) The animals can eat the soil and absorb the nitrogen through their digestive system
Answer: C) Plants absorb the nitrogen from the soil and animals can eat the plants.
Heterotrophs, specifically herbivores and omnivores, are animals that eat plants (autotrophs) to get the nutrients they need. Those that eat the plants get the nitrogen from the plant that has absorbed it from the soil. Omnivores and carnivores eat the herbivores to get nitrogen that way. For more more information, take a look at the nitrogen cycle.
In cats grey color (G) is dominant to white color (g). If a white female has kittens with a heterozygous male, and the mother is showing that she will be having 9 Kittens, how many kittens would you expect to be white? (Round down to the nearest whole number, you cannot have partial kittens)
Answer:
Rounding down to the nearest whole number, 5 Kittens will be white.
Explanation:
Available data:
grey color (G) is dominantwhite color (g) is recessivewhite female, ggheterozygous male, Gg9 KittensCross:
Parental) Gg x gg
Phenotype) Grey White
Gametes) G g g g
Punnet square)
G g
g Gg gg
g Gg gg
F1) Genotypes:
1/2 = 50% will be Gg
1/2 = 50% will be gg
Phenotypes:
1/2 = 50% will be Grey (Gg)
1/2 = 50% will be white (gg)
To calculate the number of kittens that will be white, we need to consider the proportions of cats that will be white in the F1 and that the total number of kittens is 9. So
100% of the progeny ------------------------------- 9 kittens
50% of the progeny----------------------------------X = (50 x 9)/100 = 4.5 kittens ≅ 5 Kittens
A cat can not have 4.5 kittens, so we must round down to the nearest whole number. 4.5 ≅ 5 Kittens

Answer:
the leaf of a plant takes the sunlight and converts it into food the stem and roots are for stability and for water absorbtion
Explanation:
Answer:
Seed plants have three main parts that serve specialized functions: roots, stems, and leaves. Roots help to anchor the plant in the ground as well as absorbing water and nutrients from the soil. ... Leaves carry out photosynthesis, which is the most important way that plants produce the energy to live.
Explanation:
An investigation was carried out over a five-year period to measure the effect of color on the survival of trout in a stream. The stream contained many brightly colored stones and food was plentiful. At the start of the investigation (year 0), 100 bright-colored trout and 100 drab-colored trout were placed into a section of the stream that had been blocked with netting. Investigators monitored the trout populations for five years and recorded the water condition each time a count was done. The data collected are shown in the table below.
Year Bright colored trought Drab colored trought condition of water
0 100 100 clear
1 64 36 clear
2 86 25 clear
3 25 77 cloudy
4 14 86 cloudy
5 90 9 clear
How does this demonstrate that natural selection depends on the environment? This will be graded based on your overall claim and supporting statements, use of direct evidence from the data table, and your reasoning (CER).
Explanation:
In the given question, the data has been collected for the population of two variations of colour in trout against their environment.
Natural selection refers to a mechanism of evolution by which species evolve as a consequence of their environment.
From the data, we can predict that the brightly coloured trout have better chances of survival in the clear water as the number of individuals of bright-coloured trout is found to be high in clear water.
The number of darkly coloured trout is found to be high in cloudy water in the data which shows that the chances of survival of these trout are better in the cloudy water.
The trait which increases the reproductive fitness of the organism will pass on to their generations that is will be inherited.
This shows how the population of trouts have adapted to survive in a different environment or how nature selects the different variations of the population of trout.

What is a stationary location where volcanoes form when the convection in the asthenosphere creates a column of material that rises until it reaches the crust called?
Answer:
The continental plate is the location where volcanoes form when the convection in the asthenosphere creates a column of material that rises until it reaches the crust.
Explanation:
Volcanoes form at the edges of Earth’s tectonic plates. When the continental plate moves over the oceanic plate, it causes the oceanic plate to descend into the mantle where some of it melts, and the molten material moves into the mantle above the plate and causes the mantle to melt.
This liquid rock, called magma, rises to the surface because it is less dense then the surrounding rock, a volcano forms when the magma reaches the surface of the Earth at the continental plate.
