11. Which part of a plant cell contains chlorophyll?

Answers

Answer 1

Answer:

Explanation:

chloroplasts

In plants, photosynthesis takes place in chloroplasts, which contain the chlorophyll. Chloroplasts are surrounded by a double membrane and contain a third inner membrane, called the thylakoid membrane, that forms long folds within the organelle.

Answer 2

The part of a plant cell that contains chlorophyll is the chloroplasts

The main components of the plasma membrane contain hydrophobic and hydrophilic regions that give the membrane selective permeability. Which of the following is the
main component that creates the hydrophobic and hydrophilic regions? (3 points)
a. Cholesterol molecules creating membrane fluidity
b. Carbohydrates for cell recognition
c. Glycolipids containing hydrophobic lipid portion
d. Phospholipids containing hydrophobic fatty acids tails

Answers

Answer:

The main components that creates the hydrophobic and hydrophilic regions of the plasma membrane are phospholipids containing hydrophobic fatty acids tails.

Explanation:

Phospholipids are the main component of the cell membrane —lipid bilayer— and responsible for its selective permeability.  Each phospholipid is composed of one glycerol molecule, which forms the head, and two fatty acid tails, plus one phosphate molecule.

In the lipid bilayer, the phospholipid heads are oriented towards the surface, while the tails are located inside, allowing interaction with both polar and apolar molecules.

The hydrophilic regions of the membranes are in contact with the liquids of the extracellular and intracellular spaces, while the hydrophobic region is inside the membrane, limiting the passage of polar molecules or ions.

The other options are not correct because:

    a. Cholesterol molecules are part of the membrane, but are not responsible for the hydrophobic and hydrophilic regions.

    b. Carbohydrates for cell recognition do not determine membrane permeability.

    c. Glycolipids, like integral proteins, are part of the membrane, but do not determine the polarity of the regions.

Becky is experiencing chronic pain from a medical condition that cannot be treated. In order to minimize the long-term emotional response to her pain, she would choose a modification of her a. Parietal cortex. b. Prefrontal cortex. c. Primary somatosensory cortex. d. Dorsal lateral thalamus. e. Posterior cingulate cortex

Answers

Answer:

b. Prefrontal cortex.

Explanation:

The prefrontal cortex is the cerebral cortex that covers the frontal lobe in the brain. The prefrontal cortex plays important roles in pain processing, as well as in pain modulation. In addition, this brain area is connected to other brain regions including the hippocampus, thalamus, amygdala, and further areas of the cerebral neocortex. It has been shown that changes in gene expression patterns, glial cells, neurotransmitters and inflammatory processes are triggered in the prefrontal cortex during both acute and chronic pain, and these alterations are able to modify its functioning, structure, and connectivity.

Explain how to focus a microscope using the high power lens. Include any safety issues you need to be aware Answer​

Answers

Answer:

Include any safety issues you need to be aware of. Answer: To focus a microscope using the high-power lens you have to use the focus adjustment knob but be careful because if you crank down too hard, you can damage the microscope and the slide.

Explanation:

Look through the eyepiece (1) and move the focus knob until the image comes into focus. Adjust the condenser (7) and light intensity for the greatest amount of light. Move the microscope slide around until the sample is in the centre of the field of view (what you see).You must be very careful when using the high power lenses so you do not jam them into the slide. Ocular Lens - The ocular lens, or eyepiece, magnifies the image.

Answers

Answer:

These are just the answer key. You will have to fill in the lower half of the questions yourself. I did not consider 32% and 1.6% approximately the same but the answer key did.

Hope this helps:)

Explanation:

The box’s measurements are: length = 50 cm, width = 25 cm, and height = 25 cm. The measurements of the block are: length = 10 cm, width = 10 cm, and height is 5 cm.

Out of 100 marble drops or shots, the marble hit the block 32 times.

volume of the box = 50 × 25 × 25 = 31250 cm 3

volume of the block = 10 × 10 × 5 = 500 cm 3

Ratio = 500/31250 = 0.016 × 100 = 1.6%

The volume of the block is 1.6% of the volume of the box

Ratio = 32 hits/100 shots = 0.32 × 100 = 32%

The block was hit 32% of the time.

Percentages will be similar and both be small percentages

Answers will vary.

Explain 3 ways of checking soil depletion​

Answers

You can check soil depletion by:

1. Contour ploughing

Ploughing along contours on a slope prevents soil from being washed away by rains and or by surface run-offs. Contours act like bunds. Terraces are leveled into step-like small fields with even slopes. Doing this is common in Asian countries.

2. Terrace Farming

On hilly slopes, terraces act as bunds and prevent the soil from being washed away by running water. This is practiced in Asia and the USA.

3. Strip Cropping

In this system, crops are grown by alternate strips of land in order to check the effect of the winds.

state 4 ways by which through which a soil is depleted ​

Answers

Answer:

Explanation:

Leaching – Plant nutrients are lost beyond the reach of plant roots. Usually caused by excessive rainfall washing nutrients deep down into sub-soil beyond new roots reach.

Soil erosion – Top soil is lost by the agent of erosion e.g. wind, water.

Monocropping – This utilizes only specific nutrients from a particular zone making it exhausted. -It also causes accumulation of certain pests and diseases.

Continuous cropping –This continuously exhaust the fertility of land unless the the land if fallowed.

Change of soil PH -Use of either acidic or basic fertilizers affect soil pH and Consequently the presence of micro-organisms hence soil fertility affected.

Burning of vegetations –Destroys organic matter and soil structure. Nutrients are lost and soil exposed to erosion.

Accumulation of salts – Common in waterlogged areas and semi-arid areas in which poor drainage causes evaporation during the dry periods, making the soil saline.

Viruses are not alive

Explanation:

Viruses are acellular structures capable of performing some biological functions.

What are viruses?

Viruses are parasitic structures made of an outer protein capsid and genetic material which are able to replicate in a living cell and thus cause infection in the cell.

Viruses hijack the replicative machinery of the host to produce copies of its own genetic material. A single infected cell is capable of producing thousands of viruses.

The virus only injects the nucleic acid inside the target cell, the envelope and capsid are left outside. The hijacked genetic machinery of the host produces further copies of the nucleic acid, capsid and envelope.

These structures are assembled to give rise to new viruses.

If a large number of viruses are synthesized rapidly, it results in cell lysis. This type of infection is called the lytic cycle.

If the virus genome incorporates with the host genome, it is present there silently and being replicated. Upon receiving an activation signal lytic cycle is activated. It is called the lysogenic cycle

Therefore, viruses are acellular structures capable of performing some biological functions.

Aquatic organisms are able to survive when the temperature decreases. These organisms survive even when the surfaces of lakes and ponds are covered with ice. Which property of water best explains how aquatic organisms can survive during freezing temperatures?

Answers

Answer:

Anomalous expansion

Explanation:

Anomalous expansion of water is the abnormal way water expands when exposed to low temperature.

At 4 degree Celsius , the density at the top layer is usually at the Maximum which makes the water sinks down and then the water in the lower layer rises up.

When the temperature drops below 4 degree Celsius, the water molecules at the top then freezes leaving the denser molecules at the bottom which doesn’t freeze as a result of their high density.

This way, organisms can survive in the water due to the lower layer not freezing.
