what is adaptation give any four characters of aquatic plants
Explanation:
Animals have special features that help them to live in a particular place. Therefore this features is called adaptation.
1] Aquatic plants have leaves that float on the surface of water.
2] Thier leaves are rarely have stomata.
3] Thier leaves can perform all the work without xylem.
4] They are usually lack cuticle layer in order to avoid excessive dryness.
Answer:
The most common adaptation is the presence of lightweight internal packing cells, aerenchyma, but floating leaves and finely dissected leaves are also common. Aquatic plants can only grow in water or in soil that is frequently saturated with water.
Four characters of aquatic plants are as given below:
1) most aquatic plants donot need culticles or have thin culticles as cuticles prevent loss of water.
2) aquatic plants keep their stomata always open for they do not need to retain water.
3) on each side of their leaves are a number of stomata.
4) aquatic plants have less rigid structure since water pressure supports them.

What are amino acids?
Amino acids are molecules that combine to form proteins. Amino acids and proteins are the building blocks of life.
The nucleotide triplet that encodes an amino acid is called a codon. Each group of three nucleotides encodes one amino acid. There are 64 combinations of 4 nucleotides taken three at a time and only 20 amino acids, the code is degenerate (more than one codon per amino acid, in most cases).

line forming in the center of the sugar cane's leaves,
which can change in size and shape as it develops.The sugar cane's new leaves will become increasingly whiter, often having stunted growth, and resulting in the sugar cane being less productive than the non-
infected plants, Scientists are trying to determine
what organelle must be damaged to produce the
observed results,
White leaf disease is caused by phytoplasma. The disease infects the leaves and create white spots in them.
The farmers in Thailand are facing this issue with sugarcane crops. The organisms infect phloem tissues in sugar cane and cause the leaves to turn white.
The size and shape can change as sometimes there are fine white lines created while sometime there are white spots.
Scientists are trying to deal with such disease and an spray of liquid copper has been found beneficial to treat this disease. The white spot fungus stops to spread with the spray.

Researchers note that a plant closes its stomata on a hot, dry, windy day. What statement describes the plant response to these
conditions?
A)
The stomatal closings and the environmental conditions are unrelated for this plant.
B)
The stomatal closings and the environmental conditions are unrelated for
this plant.
Water loss and water stress is highest on hot, dry, windy days, so the plant
closes stomata to conserve water.
Hot, dry, windy days are not conducive to pollen spread, so the plant closes
its stomata to prevent pollination.
Photosynthesis is decreased on hot, dry, windy days, so the plant closes its
stomata to prevent carbon dioxide diffusion.
a
D)
Answer:
It is B
Explanation:
i just took it
If a plant closes its stomata on a hot, dry, and windy day, the plant response to these conditions is water loss and water stress is highest on hot, dry, windy days. So, the plant closes its stomata to conserve water.
What do you mean by Stomata?Stomata are the tiny pores present on the surface of the leaves. A huge amount of gaseous exchange may take place in the leaves through these pores for the purpose of photosynthesis.
During photosynthesis, these stomatal pores take carbon dioxide and water is gradually lost, in order to prevent this water loss in hot and humid conditions, the plant closes its stomata.
Therefore, if a plant closes its stomata on a hot, dry, and windy day, the plant response to these conditions is water loss and water stress is highest on hot, dry, windy days. So, the plant closes its stomata to conserve water.

An ecologist counted the number of eggs in randomly selected nests in a population of birds. To test the hypothesis that the number of eggs per nest follows a Poisson distribution at the 5% level of significance, you will need to compare a calculated value with a critical value.
Eggs Number of nests Prob Expected
nest, xi per fi
0 15 0.2845 19.9
1 29 0.3576 25.0
2 19 0.2248 15.7
23 7 0.1331 9.3
SUM: 70 1.0000 70.0
What are the calculated and critical values for this test?
a. calculated = 45.6; critical = 5.991.
b. calculated = 3.10; critical = 5.991.
c. calculated = 5.89; critical = 5.991.
d. calculated = 3.10; critical = 7.815.
Answer:
d. calculated = 3.10; critical = 7.815.
Explanation:
To test the hypothesis Given in the question above, we use the Chisquare goodness of fit :
The test statistic is defined as :
χ² = Σ(Observed - Expected)² / Expected
Observed = number of nests
χ² = ((15 - 19.9)^2 / 19.9) + ((29 - 25)^2 / 25) + ((19 - 15.7)^2 / 15.7) + ((7 - 9.3)^2 / 9.3)
χ² = 3.1089
The critical value :
df = n - 1 = 4 - 1 = 3
The critical value ;P(χ² at 0.05, df = 3 ) = 7.815
The nucleus of the cell is similar to the_______ system of the body.
The nucleus of the cell is similar to the Neurological system of the body.
What is Nucleus?According to the Cell Biology, nucleus may be a membrane found in organism cells.
The nucleus contain all of the cell's ordering except mitochondrial DNA and in plant cell, Plastid DNA.
Nuclear DNA is organized as multiple long linear molecules in a very complex form with a large variety of proteins, like histones, to make chromosomes.
The nucleus maintains the integrity of sequences and controls the activities of the cell by regulation gene expression—the nucleus is, therefore, the control center of the cell
The nucleus contains nearly all of the cell's polymer, enclosed by a network of fibrous intermediate filaments and enveloped in an exceedingly double membrane referred to as the "nuclear envelope".
The nuclear envelope separates the fluid within the nucleus, referred to as the living substance, from the remainder of the cell. The scale of the nucleus depends on the scale of the cell it's contained in, with a nucleus usually occupying 8% of the whole cell volume.
The nucleus is the largest organelle in animal cells.
For example- In mammalian cells, the average diameter of the nucleus is approximately 6 micrometers (µm).
What is Neurological System or Nervous System of the body?The Nervous system could be a extremely advanced a part of associate degree animal that coordinates its actions and sensory data by sending signals to and from completely different components of its body.
In vertebrates it consists of 2 main components, the central system (CNS) and therefore the peripheral system (PNS). The CNS consists of the brain and neural structure.
The function of the system is to send signals from one cell to others, or from one a part of the body to others and to manage the body.
It will this by extracting data from the setting exploitation sensory receptors, causing signals that encrypt this data into the central system, process the data to work out associate degree applicable response, and causing output signals to muscles or glands to activate the response.
