To test how fertilizer affects tomato plants, a farmer divided a field of young
tomato plants into 10 plots of equal size. The farmer then put fertilizer on half
of the plots and no fertilizer on the other half of the plots. What is the control
group in this experiment?

Answers

Answer 1

Answer:

The plots with no fertilizer

Explanation:

In an experiment, the control group is used as a comparison for the experimental group (the group being actively changed and observed).

So, in this experiment, the control group is the plots with no fertilizer.

This acts as a good control group because it provides a normal standard to show the effect of fertilizer on the tomato plants.

So, the control group in this experiment are the plots with no fertilizer.

Why is avian influenza (H5 N1) rarely transmitted from poultry to humans? Why is it is often lethal
in humans? Why is it rarely spread from person to person?

Answers

Answer:

Lacks the right key to unlock many cells.

Explanation:

Avian influenza (H5 N1) rarely transmitted from poultry to humans because it lacks the right key to unlock many cells in the upper respiratory tract so due to this action the virus is rarely transmitted to humans. Sometimes it is lethal to humans due to absence of antibodies for this type of virus. It is rarely spread from person to person due to inability to enters the other human body.

You are studying nuclear lamins and use recombinant DNA technology to alter the coding sequence of a nuclear lamin gene. The alteration you make creates a situation such that the gene now codes for a nuclear lamin protein that can no longer be phosphorylated when the nuclear envelope is broken down during mitosis. What do you predict would happen if the cell only had the altered nuclear lamin gene (and not the unaltered version)

Answers

Answer:

Nuclear lamins will no longer disassemble during mitosis

Explanation:

The nuclear lamina is a fibrillar network inside the nucleus of eukaryotic cells, between the inner nuclear membrane and the peripheral chromatin. Nuclear lamins (also called simply lamin proteins) are intermediate filament-type proteins and represent the major building blocks of the nuclear lamina. During mitosis, the nuclear lamina is disassembled by hyperphosphorylation of nuclear lamins and lamina-associated proteins. The protein responsible for phosphorylating nuclear lamins is p34cdc2, a protein kinase that has a key role in controlling cell cycle progression. In consequence, a mutant form of the nuclear lamin proteins that cannot be phosphorylated will no longer be able to disassemble during mitosis.

In the Avery, MacLeod, and McCarty experiment, the transforming extract from virulent bacteria was treated with DNase, RNase, or protease before being mixed with nonvirulent bacteria.

Answers

Nothing

Explanation:

A. Control variables generally entail little or no system change. To see if the method worked, the researchers required a positive control in which the heat-killed virulent bacteria invariably transformed the non-virulent microorganisms. This positive control involves adding "nothing" to both the heat-killed virulent bacteria before mixing them with the non-virulent bacteria.

Answers

Answer:

D - How trichoplax adhaerens eats by engulfing it's food

Phagocytosis is a process in which Trichoplax adhaerens eats by engulfing its food, which is in Option D. It is a process by which the cells engulf the food that is coming from the outside of the cell.

What is phagocytosis?

The cell has many organelles, such as the lysosome, vacuole, cell nucleus, etc., but each organelle has a special function, and one organelle cannot take over the function of another organelle. The lysosomes have a very unique and acidic environment that destroys the organelles, such as old organelles, and kills viruses, etc.

When outside food particles or pathogens enter the cell, they enter as a vacuole, and the cell transports them from the outside to the inside through a variety of processes. The cell then eats them, a process known as phagocytosis, and if it is a virus, the lysosome degrades it.

Hence, Phagocytosis is a process in which Trichoplax adhaerens eats by engulfing its food, which is in Option D.

Why is The sun is the ultimate source of energy
for all living organisms.'

Answers

The answer is: The sun is called the ultimate source of energy because it is the source of almost all energies of the earth. Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis. Animals eat plants and use that same chemical energy for all their activities.

Answer:

"Sun is the ultimate energy source for all living organisms."

✴This is because plants need sunlight to make food through photosynthesis. This food is consumed by the animals and human-beings. Carnivores indirectly depend on plants for their food. So, if Sun is not there there will be no life on earth.

✴Secondly, sunlight is a good source of Vitamin-D.

Vitamin D is essential for strong bones, because it helps the body use calcium from the diet. Traditionally, vitamin D deficiency has been associated with rickets, a disease in which the bone tissue doesn't properly mineralize, leading to soft bones and skeletal deformities. So if sunlight is not there it can result in loss of Vitamin-D which can cause deficiency diseases.

✴If sunlight is not there there will be no day on Earth. Light will not reach our Earth. Every time there will be only darkness.
