Answer:
253 m
Explanation:
The height in meters must the student climb in order to reach the top of the hill is 253 meters. The correct option is B.
What is the height?Height is a measurement of vertical distance, or vertical extent (how “tall” something or someone is) (how “high” a point is).
Climbing is the activity of ascending a steep topographical object with one's hands, feet, or any other part of the body, which can range from the world's tallest mountains (e.g., the eight-thousanders) to little stones.
The image of a mountain is given which is climbed by a person. There are different heights of the mountain is given. The height that is a must-climb by the student to reach at the top is 253 meters.
Therefore, the correct option is B. 253 m is the height of the mountain to reach the top.

Please help it’s biology!!!!!!
Answer:
25%
Explanation:
If a parent is heterozygous, it has 2 difterent alleles. Both parents are heterozygous for blood type A, so the genotype is AO. A masks the O because A is dominant over O, so A is the blood type.
Create a punnett square to find possible offspring
AA = Blood type A
AO = Blood type A
OO = Blood type O
There is 1 child out of 4 that have blood type O. So to find the percentage divide 1 and 4 and multiply by 100.
1÷4×100 = 25
when two heterozygous individual are crossed,the proportion of the offspring that are true breeding for dominant trait is
Answer:
75%
Explanation:
If you drew a Punnett Square, you will see that the possible outcomes would be AA, Aa, aA, and aa. Three out of the four would exhibit the dominant trait.
which type of feature forms suddenly where intense compression deforms the rock area
Answer: The options are not given, here are the options gotten from another site.
A. volcano
b. normal fault
C. folded layers
D. reverse fault
The correct answer is Reverse fault.
Explanation:
This is because Reverse fault is caused by compressional stress which means rocks pushing over each other. It is the opposite of normal fault.
Reverse faults are exactly the opposite of normal faults.which occur when the hanging wall rises above and it is also relative to the footwall. Reverse faults plane are vertical and occur in areas with compression (squishing).
Describe the connection between the digestive and circulatory systems (in detail)
Answer:
Explanation:(1) Digestive System gets nutrients (good) from food and hands it over to the blood and Circulatory System then carries those nutrients where they need to go. (2) Filters out waste from food and pushes it through intestines and out the body (and you know how and where it gets out).
A. El átomo de Thomson se caracteriza por ser esférico, con carga positiva, con electrones partículas alfa α partícula rebotada incrustados en él
Answer:
Debido a la presencia de partículas pesadas.
Explicación:
Debido a la presencia de carga positiva en el núcleo del átomo de Thomson, las partículas alfa α rebotaron cuando chocaron con el protón porque el protón es una partícula pesada y la presencia de neutrón la hace más pesada. Debido a la presencia de partículas pesadas en el núcleo, las partículas alfa no pueden atravesarlo. Solo puede pasar a través del átomo de Thomson donde hay un espacio vacío en el átomo.

Why did DNA technology lead to more use of cladistics?
A. It showed that the Linnaean system was very accurate.
O B. It showed that most traits result from genetic drift.
O C. It showed that different looking animals are actually related.
OD. It showed that gene flow happens between populations.
SUBMIT
Answer:
The correct answer is - C. It showed that different-looking animals are actually related.
Explanation:
DNA technologies help in developing the lineage of the organisms and more use of cladistics. DNA techniques help in determining which animals were closely related by studying the genetic change.
It is used to established new evolutionary relationships between different-looking animals as minor genetic changes may lead to morphological changes.
Plants play a role in this cycle by completing photosynthesis:
Answer:Plants don't eat food; they have to create it for themselves. They do this through a process known as photosynthesis. Photosynthesis uses water, carbon dioxide from the air and energy from the sun or another light source to create glucose or sugar. This glucose provides the energy the plant needs in order to survive

Each level of the energy pyramid is called a trophic level. How does the amount of energy available to organisms differ at each trophic level in a food chain?
Answer:
Most of the food energy that enters a trophic level is "lost" as heat when it is used by organisms to power the normal activities of life. Thus, the higher the trophic level on the pyramid, the lower the amount of available energy

why is it important for plant's to store food?
Answer:
Storing the food helps them to use it in winter and survive because there is very little sunlight available and so they photosynthesis less. ... When they have extra food they store it in their seeds and when the seed grows it gets it's food from the plant until the plant is able to photosynthesis and produce its food.
Answer:
It's important for plants to store food, as food is a source of nutrition, which is necessary for survival. Rather than just eating the food, storing it is a good way to ensure nutrients during droughts or other harsh conditions that make it hard to find food.

And also tell what is 1dm3
Explanation:
1 dm3 is a cube with dimension 1 deci meter
One cubic decimeter is the unit of volume which is exactly equal to one litre.
What is meant by volume ?Volume of an object is defined as the amount of space within the object which the matter can be occupied.
Here,
It is said that volume is a derived quantity.
Volume is said to be a derived quantity because, volume is the product of length, breadth and height of a three-dimensional shape.
It is given that,
1 L = 1000 mL
1 L = 1 dm³
1L = (10cm)³ = 1000 cm³
We know that, 1 cm = 10⁻²m
So, we can write that,
1L = 1000 x (10⁻²m)³
1L = 10³ x 10⁻⁶m³
Therefore,
1L = 10⁻³ m³
Or
1 m³ = 1000 L
1 dm³ or 1 cubic decimeter is the unit of volume, which is equal to one litre.
Hence,
One cubic decimeter is the unit of volume which is exactly equal to one litre.

Interferons Interferons reduce macrophage chemotaxis to the infection. interfere with viral replication. prevent viruses from entering a cell. bind to viruses and destroy them. prevent viruses from leaving a cell.
Answer:
interfere with viral replication
Explanation:
Interferons (IFNs) are proteinous molecules, which are part of the innate immune system of our body. Interferons are produced in response to viral infections and they often specialize in preventing the virus pathogen from replicating or multiplying in the host cell.
As their name implies, INTERFERONS interfere with the replication of viral pathogens, hence, preventing the virus from further invading the host cell. This is done at the innate immunity level.
