As time progressed and technology improved, microscopes were able to give clearer images of extremely tiny objects. How did this development advance the cell theory?
Answer:
Robert Hooke is accredited with observing the first cells in 1665. At that time, Robert Hooke used a microscope to look at cork cells.
In 1670, Antoni van Leeuwenhoek was accredited with being the first scientist to discover pond life. He used lenses to make the discovery.
Robert Brown (1773-1858) used a microscope to discover the nucleus.
Explanation:
The development of technology extremely advances the concept of cell theory to a larger extent. This facilitates scientists to deliver a more accurate and detailed image of tiny objects like cells and their organelles.
What are the three assumptions of cell theory?The three assumptions of the cell theory are as follows:
All living organisms whether plants or animals are made up of cells.A cell is the smallest unit of all living organisms. A Cell is the basic structural and functional unit of organisms.Prior to the cell theory, English scientist Robert Hooke in 1665, first discovered a dead cell in a thin slice of bottle cork under a microscope. Later in 1674, Antony Von Leeuwenhoek discovered the living cell for the first time with the improved version of the microscope.
In 1836, Robert Brown discovered a cell's nucleus. Then it comes to the time of 1839 when cell theory was proposed by Theodore Schwann and M. Schleiden. Till then, there was a lot of improvement is seen in the field of technology which complete changes the purpose and method of scientific analysis.
Therefore, the development of technology extremely advances the concept of cell theory to a larger extent.

Which of the following accurately describes the word equation for cellular respiration? *
A.) Glucose + oxygen --------> carbon dioxide + water + energy (ATP)
B.) Carbon dioxide + water ---(light energy)---> glucose + oxygen
C.) Glucose + water --------> oxygen + carbon dioxide = energy (ATP)
D.) Carbon dioxide + energy ---(light energy)---> oxygen + water + glucose
Cellular respiration is the vital living process to produce ATP from food. The word equation that best represents the process is Glucose + oxygen → carbon dioxide + water + energy (ATP). Thus, option A is correct.
What is cellular respiration?Cellular respiration is the chemical series that involves the production of energy molecules (ATP) to power cellular activities and metabolic functions. It involves, glycolysis, Kreb's cycle (TCA), and oxidative phosphorylation to break the sugar molecules.
The word equation for cellular respiration can be given as:
Glucose + oxygen → carbon dioxide + water + energy (ATP)
Here, glucose and oxygen come from photosynthetic reactions through eating and breathing that undergo breaking to yield water and carbon dioxide, and waste along with ATP.
Therefore, option A. Glucose + oxygen → carbon dioxide + water + energy best represents cellular respiration.

Plants reduce soil erosion by protecting the land from the weather. Which spheres are involved?
Group of answer choices
Atmosphere and biosphere
Atmosphere and geosphere
Hydrosphere and geosphere
Geosphere and biosphere
Sometimes fires burn large areas of forests that are part of the biosphere. Other than the biosphere, which of Earth's other spheres is a forest fire most likely to affect? (choose 2)
Group of answer choices
geosphere
cryosphere
hydrosphere
atmosphere
Answer:
1.) Atmosphere, geosphere
2.) Atmosphere, hydrosphere
Explanation:
1.) The atmosphere is responsible for the weather and the geosphere is made up of the earth and the plants roots.
2.) The smoke from the fire can cause a disturbance with certain levels of gas components in the air and the ash can pollute sources of water and harm wildlife.
The sphere involved in the reduction of soil erosion is geosphere and biosphere. Earth's other spheres is affected by forest fire is atmosphere and geosphere. The correct option for question 1 is D and for 2 are A and D.
What is biosphere?The biosphere is largely made up of all ecosystems that are present on Earth.
The biosphere encompasses everything from deep forest root systems to the complete darkness of intertidal zone, lush rain forests, high mountain peaks, and buffer zones like this one, where ocean and terrestrial ecosystems collide.
A hydrosphere is a planet's total amount of water. The hydrosphere includes water on the planet's surface, underground, and in the atmosphere. The hydrosphere of a planet can be liquid, vapor, or ice.
The geosphere contains all of Earth's rocks, from near the interface rock beneath the crust to ancient, towering mountains to grains of sand on a beach.
Thus, correct option for question 1 is D and for 2 are A and D.

Answer:
Sensing danger and sweating
Answer:
Many animals regulate their body temperature through behavior, such as seeking sun or shade or huddling together for warmth. Endotherms can alter metabolic heat production to maintain body temperature using both shivering and non-shivering thermogensises.

What is the main idea of this text? Before the invasion, scientists developed computer models to predict the effect of the zebra mussels. But they were still surprised by what happened. By 1992, there were so many zebra mussels, scientists estimate
they were filtering a volume of water equal to all of the water in the estuary every 1-4 days during the summer. In the years right after the invasion, phytoplankton fell by 80 percent. Zooplankton (which eat phytoplankton) declined by half. And the smallest zooplankton (called micro-zooplankton), fell by about 90 percent. By 1994, scientists hypothesized that zebra mussels were responsible for these changes. The mussels were filtering huge amounts of phytoplankton from the water. Less phytoplankton meant less food for zooplankton, so their numbers were shrinking too. Competition was taking place and the
zebra mussels seemed to be winning.
A. In the years right after the invasion, zebra mussels evolved and adapted to the Hudson River ecosystem.
B. In the years right after the invasion, zebra mussels caused a number of changes in the Hudson River ecosystem and food web.
C. In the years right after the invasion, zebra mussels did not have a major impact on the Hudson River ecosystem or food web.
D. At first, zebra mussels did not have any impact on the Hudson River ecosystem, but their impact increased over time.
please help me I will give out the brain thing and extra points.
Answer:
B
Explanation:
I don't really know to be honest. I would guess it's B because it mentions the impacts, such as increased population in the mussels and decrease in zooplankton and phytoplankton.
