Explanation:
Of the three waves shown, Wave 2 has the greatest
wave speed, because it has more crests than the other ropes
O frequency because it has a large wavelength than the other ropes
wave speed because the rope is moving up and down faster than the other ropes
frequency, because there are more crests in the same length of rope than there are in the other waves
Answer:
D. frequency, because there are more crests in the same length of rope than there are in the other waves
Explanation:
Wave frequency is defined as the number of waves passing a fixed point at a given time.
Wave frequency is highly influenced by the number of crests in the wave that pass the fixed point in 1 second. It means, more is the number of crests in the same length of rope, the higher will be the wave frequency.
Wave 2 has a maximum number of crests and thus wave 2 has the greatest wave frequency in comparison to other ropes.
Hence, the correct answer is "D".

Answer: If a land fertilizer were used on the algae it would severely damage the plant and suffocate it.
Explanation: Fertilizers are used by homeowners to maintain and improve landscape beauty and quality. In recent years, increased use of home lawn and garden fertilizers has caused concern about pollution of lakes and groundwater. Proper fertilizer application can enhance plant growth without polluting the environment. Yet, misuse of fertilizer may not only harm the environment—especially ground and surface water—but may in fact result in injury to landscape plants as well. The nutrient phosphorus harms clear, free water by creating algal blooms. This process, known as eutrophication, turns the water green, clouds the water, causes odor problems, and depletes the oxygen for fish and other species, effectively suffocating them.
Answer:
Well knowing that most fertilizers help algae grow, my prediction is that the algae expectantly grow at a high rate. The rain would also help the growth and might even get the algae in the water systems.

Large, circular lily pads are able to float on the water's surface.
Answer:
true
Explanation:
they're buoyancy
The property of water in "Large, circular lily pads are able to float on the water's surface" is cohesion.
What is cohesion?Cohesion refers to the attraction of one water to another. This force will cause the water in the lake to develop surface tension. The large and thin leaf of the water lily gives it a low force per area.
The leaf will float above the water if the force acting on the surface is not greater than surface tension. The ability of water spiders to walk on the surface tension of the water.
The leaves of lotus float on the water because the bottom of the leaves have edges and thick ribs that capture air between them, which helps them to float on the water.
Thus, the property of water that is shown in the given statement is cohesion.

If an H is for tall trait which is dominant and h is the recessive trait for short,
which of the following crosses will result in 1:1 tall:short progeny (offspring).
A) HH Xhh
B) hh X hh
C) Hh X hh
D) Hh X Hh
Answer:
The cross that guarantees a height trait ratio in the offspring of 1 : 1 high/low is Hh X hh (option C).
Explanation:
For a characteristic such as size, where tall (H) is the dominant trait and short (h) is the recessive, the crossing of a tall heterozygous (Hh) individual with a short one will have a probability that half of the offspring will be tall and the other half short.
This can be demonstrated with a Punnett square:
Cross Hh X hh
Alleles H h
h Hh hh
h Hh hh
Based on this result, half of the offspring will be tall, with genotype Hh, and the other half short, with genotype hh, which corresponds to a tall : short ratio of 1 : 1.
In the other options is not possible to obtain this result:
A) HH Xhh = 100% Hh.
B) hh X hh = 100% hh.
D) Hh X Hh = 50% Hh, 25% HH and 25% hh.

Plants like the stinging nettle seen here have sharp, needle-like hairs that inject a burning chemical into animals that touch the stems or leaves. These hairs are used for A) protection. B) reproduction. C) photosynthesis. D) attracting insects.
Answer:
A. Protection
Explanation:
These plants have this external protection system to protect them against being eaten by these animals.
In cases where these plants are approached to be eaten by these animals, these systems which in this case are these hairs tend to make an effort by discomforting the approaching animals.
The animals upon sensing this discomfort retreat from feasting on these plants which thus prolongs their lives and prevent them from being eaten by these animals

What would happen if the mitochondria were missing from a cell?
Answer:
We'd be in big trouble...
Explanation:
The mitochondria is the powerhouse of the cell, without mitochondria (singular, mitochondrion), higher animals would likely not exist because their cells would only be able to obtain energy from anaerobic respiration (in the absence of oxygen), a process much less efficient than aerobic respiration.
The absence of mitochondria would have a profound effect on cellular function, including the cell's ability to produce energy, regulate ROS levels, and control important signaling and metabolic pathways. Such a cell would likely be unable to survive for very long.
What is the effect of mitochondrial removal?Without mitochondria, the cell would not be able to generate ATP through aerobic respiration, which takes place in the mitochondria. Instead, the cell would have to rely on other, less efficient metabolic pathways to produce energy. Mitochondria are also important for regulating the levels of reactive oxygen species (ROS) in the cell. Without mitochondria, the levels of ROS would likely increase, leading to oxidative damage to the cell's proteins, lipids, and DNA. Mitochondria play important roles in cell signaling pathways, including those involved in apoptosis (programmed cell death) and calcium signaling. Without mitochondria, these pathways would likely be altered, which could have profound effects on cellular function and survival.
Hence, such a cell would likely be unable to survive for very long.

Explanation:
what determines how far south the cold air from the north pole travels
Answer:
Please mark as Brainliest.
Explanation:
Polar easterlies are the cold and dry wind that blows from the polar regions (North pole and South pole) to the region of 60 degrees latitude. This type of wind is formed due to the sinking of the cold air resulting in the formation of a high pressure zone at both the poles. This wind when blows from the poles to the 60 degrees latitude, it slightly gets deviated towards the western side because of the effect of the Coriolis force. This Coriolis force comes into the picture due to the earth's continuous rotation.
Thus, the polar easterlies determines how far south the cold air travels from the North Pole.
Earth is 150 million kilometers from the sun, and the solar "wind" travels at about 400 km/sec. How long does it take particles from a solar storm to reach Earth? (Hint: Time = Distance / Speed. To convert from seconds to hours, divide the time in seconds by 3600.)
Answer:
The correct answer is - 4.34 days.
Explanation:
Given:
Distance from the sun to earth = 150 million kilometer
= 1500,00,000 km
The solar "wind" travels = 400 km/sec
= 400*60*60 km/ hour
= 1440000 km/hour
Then time = distance/speed
time = 1500,00,000 km/1440000 km/hour
time = 104.166666667 hours
time = 104.166666667/24
= 4.34 days.

Why are there fewer tuskless elephants born after the war (ages 10-20 years old)?
Elephant tusks are either present or absent due to genetics, specifically the existence of key genes that regulate tusk growth. Environmental elements, however, can also affect the proportion of tuskless elephants in a population.
Elephants are frequently hunted down during conflicts or wars for their ivory tusks, which are highly sought-after on the illicit market. Over time, the population of elephants with tusks may decline as a result of this selective hunting of those with them.
The age range of 10 to 20 years old is essential because it coincides with the period of time when elephants usually begin to grow their tusks. Around the age of 6 to 8 years, young elephants may start developing their tusks, and by the time they are 10 to 20 years old, their tusks should typically be more noticeable and developed.
It is possible that many young elephants with developing tusks will be killed if a conflict or a period of rampant poaching takes place during this crucial time, which will reduce the number of tusked elephants in the population. After such a conflict or a period of heavy poaching, there can be a larger percentage of tuskless elephants between the ages of 10 and 20.
This theory makes the assumption that there was greater poaching or selective hunting occurring during the conflict, which would have a disproportionately negative effect on elephants with tusks. In order to provide a more comprehensive knowledge of the issue, additional examination of local conditions and data would be required. The individual situations and variables affecting elephant populations can differ.

Explanation:
What would happen if the enzyme used for cellular respiration or photosynthesis to break after a few cycle? Why?
Answer:
Please mark as brainliest!!!
Explanation:
Cells face a related problem when they break down fuels, such as glucose, to produce ATP. If the cell’s supply of ATP is low, it would do well to break down glucose as quickly as possible, replenishing the ATP it needs to “keep the lights on.” If the supply of ATP is high, on the other hand, it might not be such a good idea to oxidize glucose at top speed. ATP is an unstable molecule, and if it sits around in the cell too long, it’s likely to spontaneously hydrolyze back to ADP. This is like the case of the melted ice cream sandwich: the cell has spent glucose to make ATP, and that ATP ends up going to waste.
It’s important for a cell to carefully match the activity of its fuel breakdown (pathways to its energy needs at a given moment. Here, we'll see how cells turn cellular respiration pathways “up” or “down” in response to ATP levels and other metabolic signals.
