Explanation:
The most common and fastest way of measuring ocean depth uses sound. Ships using technology called sonar, which stands for sound navigation and ranging, can map the topography of the ocean floor. The device sends sound waves to the bottom of the ocean and measures how long it takes for an echo to return.

how does the structure of the leaf allow it fulfil the requirements for gas exchange surface?
(pls don't put it in a file or pls no link) :)
Explanation:
The structure of the leaf is adapted for gas exchange. The cells in the spongy mesophyll (lower layer) are loosely packed, and covered by a thin film of water. There are tiny pores, called stomata , in the surface of the leaf. Most of these are in the lower epidermis, away from the brightest sunlight.
The stomata control gas exchange in the leaf. Each stoma can be open or closed, depending on how turgid its guard cells are.
In the light, the guard cells absorb water by osmosis, become turgid and the stoma opens.
In the dark, the guard cells lose water, become flaccid and the stoma closes.
Diffusion of carbon dioxide, oxygen and water vapour into (or out of) the leaf is greatest when the stomata are open.
How is DNA condensed in order to fit inside cells?
Explanation:
DNA is tightly packed up to fit in the nucleus of every cell. As shown in the animation, a DNA molecule wraps around histone proteins to form tight loops called nucleosomes. These nucleosomes coil and stack together to form fibers called chromatin.

Identify the cost or costs of hydroelectric power plants:
Water at the bottom of the reservoir lake (behind the dame contains colder water with less oxygen than surface water. When this is released into the rive downstream, it ca affect the fish living these that are accustomed to warmer, oxygen-rich water.
Dams without side channels interfere with fish needing to swim upstream to lay eggs for reproduction may not be able to get past the dams and young fish that are swimming downstream may be killed by the turbine blades. This has caused a severe decrease in sockeye salmon populations in areas of Northwest U.S.
All of these are some of the possible costs of hydroelectric power plants.
Sometimes a lot of water is released by a dam at a given time, resulting in flooding downstream. This affects both wildlife and drinking water. Flooding also often occurs during the construction of a dam as the reservoir fills in areas that were once above the water level forcing people and animals to relocate due to lost habitat.

Answer:
B: The Grasshopper population will decrease
Explanation:
Make me brainliest please
The Grasshopper population will decrease if population of grasshopper dies off.
What is Chemical spray?
population ecology and making predictions about population dynamics would be sufficiently challenging based only on the complicating qualities that living entities bring to the problem (variation and history), but an ecologist must also taken into consideration the particularities of a given system.
Grasshoppers cause serious economic damage to both crops and rangeland, although the greatest concern has been with respect to losses of livestock forage in the latter system (Hewitt and Onsager 1983, Joern and Gaines 1990).
What is lacking, however, is any substantive advance with regard to state and federal forecasting of rangeland grasshopper population dynamics that would allow limited resources to be acquired, allocated, and applied in an optimal manner.
Therefore, The Grasshopper population will decrease if population of grasshopper dies off.

Un objeto posee una energía cinética de 300J, este mismo se ubica a 4m de altura y su masa corresponde a 10Kg. ¿Cuál es su energía mecánica?
Answer: 692 J
Explanation:
La energía mecánica es la energía que se utiliza para realizar un trabajo determinado y se calcula con la suma de la energía cinética y la energía potencial de un objeto. En otras palabras, describe la energía de un objeto debido a su movimiento, posición, o ambos.
La energía cinética es el trabajo necesario para acelerar un cuerpo desde el reposo hasta su velocidad final. Entonces, es la energía que posee un cuerpo debido a su movimiento. Cuando gana energía durante la aceleración, el cuerpo mantiene la energía cinética a menos que su velocidad cambie, y el cuerpo realiza la misma cantidad de trabajo al desacelerar desde su velocidad actual hasta un estado de reposo. Por otro lado, la energía potencial es la energía que posee un objeto debido a su posición con respecto a otros objetos. Los tipos más comunes de energía potencial incluyen a la energía potencial gravitacional de un objeto que depende de su distancia al centro de masa de otro objeto (La Tierra), la energía potencial elástica de un muelle o resorte extendido y la energía potencial eléctrica de una carga en un campo eléctrico.
La unidad de energía en el Sistema Internacional de Unidades (SI) es el julio, que tiene el símbolo J.
La energía mecánica se calcula de la siguiente manera (tener en cuenta que la aceleración de la gravedad es un dato tabulado de 9,8m/s^2):
Energía mecánica = Energía cinética + Energía potencial
Energía mecánica = (1/2 * masa * velocidad^2) + (masa * gravedad * altura)
Energía mecánica = 300 J + (10kg * 9,8m/s^2 * 4m)
Energía mecánica = 300 J + 392 J = 692 J
How and why do plants need to be able to respond to their environment?
Like all organisms, plants detect and respond to stimuli in their environment. Unlike animals, plants can't run, fly, or swim toward food or away from danger. They are usually rooted to the soil. Instead, a plant's primary means of response is to change how it is growing. hope it helps have a great day and I hope you pass:)

What is the main way that fossil fuel use impacts the environment?
A) invasive species
B) water use
C) global climate change
D) soil degradation
Answer:
C. Global Climate Change
Explanation:
When fossil fuels are burned, they release carbon dioxide and other greenhouse gases, which in turn trap heat in our atmosphere, making them the primary contributors to global warming and climate change.
Global climate change is the main way that fossil fuel use impacts the environment. Therefore, option (C) is correct.
Why fossil fuels impact environment?Fossil fuels such as coal, oil, and natural gas are formed over millions of years from the remains of dead plants and animals. When these fuels are burned to produce energy, they release large amounts of carbon dioxide and other greenhouse gases into the atmosphere.
These gases trap heat from the sun and cause the Earth's temperature to rise, leading to climate change and other environmental impacts. In addition to greenhouse gas emissions, fossil fuel extraction, transportation, and processing can also have other negative impacts on the environment, including air and water pollution, habitat destruction, and oil spills.
Fossil fuel use also contributes to the depletion of finite resources and the loss of biodiversity. As a result, there has been increasing emphasis on transitioning to renewable energy sources to mitigate the negative impacts of fossil fuels on the environment.

A.(making proteins)
B.(chemical reactions)
C.(respiration)
D.(photosynthesis)
The process that is absent from animal cells is photosynthesis. The correct option is D.
What are animal cells?Animal cells are present in animals, and they are of two types, prokaryotic and eukaryotic cells. These cells are different from plant cells as they do not contain a cell wall.
Plants are autotrophic organisms that do the process of photosynthesis to perform the chemical reaction to make food. As animal cells are heterotrophic, they do not perform photosynthesis, and they do not contain chloroplast, but chloroplast is present in plant cells.
All other processes like making protein, chemical reactions, and respiration. These processes are performed by both animals and plant cells. These are necessary for both plants and animals.
Thus, the correct option is D. photosynthesis.
