Answer:
Pressure has a magnitude but no direction associated with it. Pressure acts in all directions at a point inside a gas. At the surface of a gas, the pressure force acts perpendicular to the surface. ... So the pressure would also push on the bottom of the box and on the sides.

Pros:
You can get more scientific knowledge of the mammothYou will be able to clone the mammoth easierHelping the environmentIt will help protect species that are close to extinction(can't think of anything else, sorry )Cons:
Different environmentCould go wrong and become an alienCould carry retroviruses which can harm humansMight CHANGE the environment for the worseIt might cause more species to go extinctwhats released during cellular respiration
Answer:
During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP (adenosine triphosphate).

Explanation:
describe the mechanism of blood sugar regulation (20 marks)
Insulin helps the cells absorb glucose, reducing blood sugar and providing the cells with glucose for energy. When blood sugar levels are too low, the pancreas releases glucagon. Glucagon instructs the liver to release stored glucose, which causes blood sugar to rise.
The pancreas releases glucagon when glucose levels fall too low. Glucagon causes the liver to convert stored glycogen into glucose, which is released into the bloodstream. High BG levels stimulate the release of insulin. Insulin allows glucose to be taken up and used by insulin-dependent tissues, such as muscle cells.p

Minnesota. IF EACH BALD EAGLE NEST ACCOUNTED FOR A BREEDING
PAIR, what is the probable carrying capacity of this environment? *
The carrying capacity of this environment is 225 from the graph shown.
An ecosystem is a self supporting unit in which materials and energy are exchanged. The carrying capacity of an ecosystem refers to the maximum number of species that the ecosystem can effectively sustain without breaking down.
From the graph, we can see that the population of species continues to increase until the number reaches 225. This is the carrying capacity of this environment.

elect the correct statement regarding the lungs. Select one: a. The left lung is larger than the right lung. b. Only the right lung has a hilum. c. The left lung contains three lobes while the right lung contains two lobes. d. The left lung has more bronchopulmonary segments than the right lung. e. The left lung contains two lobes while the right lung contains three lobes.
Answer:
The right lung is smaller than the right to make room for the heart.
Explanation:
so the answer is A :)
The left lung contains two lobes while the right lung contains three lobes. Therefore option E is correct.
The statement that the left lung contains two lobes while the right lung contains three lobes is correct.
The right lung is divided into three lobes: the upper lobe, middle lobe, and lower lobe. On the other hand, the left lung is divided into two lobes: the upper lobe and lower lobe.
This anatomical difference is due to the position of the heart, which is located more towards the left side of the chest. The presence of an additional lobe in the right lung allows for a better fit around the heart.
Understanding the lobes of the lungs is important in assessing and diagnosing respiratory conditions and in surgical procedures that involve lung resection or transplantation.
Therefore option E The left lung contains two lobes while the right lung contains three lobes is correct.

Explain how one change in the Earth's biosphere can
cause changes in other Earth systems.
Answer:
interaction in the Earth's biosphere cause the change in other Earth system as the biosphere and atmosphere are dynamic, constantly reflecting these interaction. and Biosphere-Atmosphere Interactions focuses on the sources and sinks of greenhouse gases (GHGs), air pollutants, particulate matter, water, and energy between the Earth's surface and the atmosphere.
The Earth's biosphere is closely interconnected with other Earth systems, such as the hydrosphere (water), atmosphere (air), and geosphere (land). Changes in one part of the Earth's biosphere can have significant impacts on other Earth systems, and vice versa
What is a biosphere?Biosphere means interactions with each other and their physical environment.
For example, changes in land use, such as deforestation or urbanization, can affect the Earth's water cycle and climate. Deforestation, for example, can lead to increased runoff and erosion, which can alter the availability and quality of water in an ecosystem. Deforestation can also lead to an increase in atmospheric carbon dioxide, as trees and other vegetation absorb and store carbon dioxide during photosynthesis. This can contribute to global warming and climate change.
Similarly, changes in the Earth's climate, such as an increase in temperature or a change in rainfall patterns, can affect the biosphere. Warmer temperatures can lead to the range expansion of certain species and the loss of habitat for others. Changes in rainfall patterns can affect the availability of water for plants and animals, which can lead to changes in the distribution and abundance of species in an ecosystem.

Which statement is true about the energy level of solids?
A.) Solids have more energy than water
B.) Solids have more energy than plasma
C.) Solids have the most amount of energy
D.) Solids have the least amount of energy
Answer:
The answer is D.) Solids have the least amount of energy
Explanation:
Because in a solid, particles are packed tightly together so they don't move much. The electrons of each atom are constantly in motion, so the atoms have a small vibration, but they are fixed in their position. Because of this, particles in a solid have very low kinetic energy.
you don need to actually chew the bread. you can just break it up into smaller pieces. which variable will you change in your investigation?
Answer: The type of bread (independent variable)
Explanation:
You can just change the type of bread you are eating and just hold it in your mouth to test your hypothesis of not having to chew the bread. It’s the easier thing to change when making the experiment. Now your bread is your independent variable because you are not changing anything else but the type of bread. Not sure if your question is talking about the technical terms for the variable or what actual variable in the experiment, so I put down both.

The diagram shows the reproductive system of a plant.
Which of the following best describes the interaction that occurs between a plant's reproductive parts during self-fertilization?
Pollen is released from the stigma and is transferred to the anther. A pollen tube grows down from the anther through the filament and fuses with the ovule, where the sperm fertilizes the egg.
Pollen moves from the ovule up through the style and is released from the stigma. The pollen is transferred to the anther, where the sperm fertilizes the egg.
Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.
The correct answer is pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.
This option correctly defines the interaction that occurs between a plant's reproductive parts during self-fertilization as it explains the pollination process and fertilization, when pollen grains are released then are transferred to the stigma the pollen tube is there that reaches ovule and the sperms fertilize an egg.
What is pollination?
Transfer of pollen from anther to the stigma of plants. Pollen is released from the anther and is transferred to the stigma. A pollen tube forms and grows through the style. The pollen tube reaches an ovule within the ovary where the sperm fertilizes the egg.

What is the Whitaker system?The Whitaker system is a classification system to order and organize the diverse biological life found on Earth. This is the most commonly-known system which orders organisms into the 5 kingdoms. What is the Whoese-fox system?This is a much less popular system of classification for biological life.
