A student observed a palisade cell using a microscope. The microscope had four objective lenses, each with a different magnification. Which objective lense should the student use?

Answers

Answer:

x4 objective

Explanation:

The student should use the x4 objective lense in order to be able to observe the palisade cell of a leaf.

The palisade cells are located below the cuticle and the epidermis of the leaf and the x4 objective will provide the largest field of view for adequate study by the student. The x4 objective is also easier to focus compared to the lower objectives.

How does the muscular system help humans maintain posture?

2.Muscles continually push bones to be straight.
3.Muscles constantly contract to help fight gravity.
4.Muscles constantly contract to help work with gravity.

Answers

Answer:

a

Explanation:

Muscles continually align themselves vertically to help maintain posture.

What is Muscular system?

Muscle fibers are specialized cells that make up the muscular system. Their ability to contract is its main characteristic. Movement is caused by muscles that are connected to blood vessels, internal organs, or bones.

Muscle contraction is the primary cause of almost all bodily movement. Cilia, the flagellum on sperm cells, and certain white blood cell amoeboid movement are examples of exceptions to this rule.

Walking and running are two examples of visible movements that are produced by the coordinated action of joints, bones, and skeletal muscles. Skeletal muscles can also make softer motions that influence different facial expressions, eye movements, and breathing.

Therefore, Muscles continually align themselves vertically to help maintain posture.

In studying the environment, nature does the experiments, scientists collect the data. How does the principle of uniformitarianism help answer questions about environmental changes?

Answers

Answer:

The principle of uniformitarianism helps answer questions about environmental changes because it gives scientists the idea that the scientific conditions that exist today have always been in existence. This makes it easier to draw correlations.

Explanation:

The principle of uniformitarianism states that the natural conditions that exist today have remained unchanged through the span of human life. This helps scientists in their understanding of nature. For example, they are better able to understand the formation of the earth as well as the uniformity of law across space and time.

Uniformity of law is an aspect of the principle of uniformitarianism which states that the laws of nature are constant across time and space. Uniformity of degree states that geological conditions have remained constant over time. These principles help scientists to better understand environmental changes.

Which of the following statements describes one way that energy is transferred in a food web?
Plants provide energy to consumers.
Energy is cycled between producers.
Consumers obtain energy directly from sunlight.
Producers store energy made by animals.

Answers

Answer: energy is cycled between producers

Explanation:

Plants provide energy to consumers, herbivorous and decomposers consumers are the only two groups that directly receive energy from plants.

What is a food web?

The process of photosynthesis in plants transforms solar energy, which makes up the vast majority of the energy in food webs, into chemical energy.

When molecules are broken down during respiration in plants, a small fraction of this chemical energy is converted directly into heat. From producers to consumers, energy flows.

The relationships between species in a biotic community that involves eating are described by food chains, food webs, and/or food networks. In other words, they demonstrate the flow of resources and energy within an ecosystem from one species to another.

Therefore, plants provide energy to consumers one way that energy is transferred in a food web, hence option A is correct.

Answer:

Option C

Explanation:

Driving force for plate tectonics is the "convection in the Earths mantle" or option C. Convection is the transfer of heat due to the movement in molecules also causing hot to rise and cold to sink. Convection currents cause the tectonic plates to move because the currents rise to the Earths surface forcing the plates to drive away from each other also known as seafloor spreading.

Rotenone, a piscicide (fish poison), interferes with the transfer of electrons between Complex I and Complex II in the process shown above. Which of the following results would be expected in the mitochondria of fish exposed to Rotenone? Why?

Answers

Answer:

Mitochondria stops working.

Explanation:

When the mitochondria of fish exposed to Rotenone, it inhibits the cellular respiration which is the main cause of death of fishes. This inhibiting of cellular respiration in mitochondria leads to reduction in cellular uptake of oxygen and this reduction is responsible for the death of fishes. This Rotenone releases by the plants present in the water as well as used as pesticides for killing of fishes.

What is the significance of karyokinesis?

There are many steps in cell division, two of which are important, the first is the division of the nucleus, known as karyokinesis, which is the process of nuclear division that includes replication of the genetic material and separation of the duplicated chromosomes and is important for the production of genetically identical daughter cells for growth and repair in multicellular organisms. The single cell is divided into two cells after cytokinesis, which occurs at the end of cell division.
