Dryopteris dilatata is in family Dryopteridaceae. The movement of plant away from spill the roots primarily work in conjunction with vascular system to reduce the absorption and transport of toxic chemicals.
What is Dryopteris dilatata?Dryopteris dilatata is a fern mainly located in deciduous or semi-evergreen family, native of Europe.
It can be grown in most cool, moist and light shaded areas. It is also called as broad buckler-fern.
As to avoid antifreeze spills, the plant roots grow far away from the area of spill. During this process roots primarily work with vascular system to reduce absorption and transport of toxic chemicals.
Thus, the correct option is b.

a point mutation changes the DNA sequence CGA to CGT but the same protein is still produced. which point mutation occurred
Answer: The correct answer is silent mutation . In this type of mutation there is no change in the phenotype of the individual which means there occurs a mutation where two different amino acid codes for the same protein .There are sequences present in the body where a point mutation occurs but the protein formed is still the same .If you will see the genotype you can easily observe that the amino acid sequence is different but the protein formed is same. Example AAA codes for lysine and the amino acid lysine is formed by AAG .

Answer:
6. Current = 8.33 Amps
7. Energy = 1200 Joules
Explanation:
Given the following data;
6. Power = 1000 Watts
Voltage = 120 Volts
To find the current flowing through;
Power = current * voltage
1000 = current * 120
Current = 1000/120
Current = 8.33 Amps
7. Power = 900 Watts
Time = 45 minutes to hours = 45/60 = 0.75 hours
To find the energy consumption;
Energy = power/time
Energy = 900/0.75
Energy = 1200 Joules

Explain why green chilies are preserved using vinegar and sugar.
Answer:
The solution in which the whole green chillies are soaked is a mixture of vinegar and water. The reason why green chillies are kept in this solution for long hours is to reduce the heat of the spice. Doing so will not only reduce the spiciness of the chillies, but will also add a tangy flavour to them.

Why is the structure of a
nucleosome so important?
Answer:
In eukaryotes, nucleosomes play major roles in chromatin organization and gene expression
Explanation:
In eukaryotic organisms, chromosomal DNA is packaged with the help of proteins called 'histones' to form chromatin. The nucleosomes represent the basic packing units of the chromatin. Each nucleosome is composed of a histone octamer containing each two histones H2A, H2B, H3 and H4 wrapped around by 147 bp of DNA. Nucleosomes act as scaffolds to form higher-order chromatin structures (i.e., 30-nm chromatin fibers and condensed chromosomes). Moreover, nucleosome histone proteins can be chemically modified at defined amino acid residues, and thus nucleosomes also provide an epigenetic layer of information that can promote or inhibit gene expression.
Normal red blood cells slide easily through narrow blood vessels. In sickle cell disease, many red blood cells change to a crescent shape like a slender moon. Crescent-shaped blood cells cause blockages in blood vessels. These blockages decrease the transport of oxygen. People with sickle cell disease often have sharp pains due to the lack of oxygen in parts of the body. The sickle cell version of the gene that causes sickle cell disease is recessive. Suppose that two parents with no symptoms have a child with sickle cell disease. What genes did the child inherit from the parents?
Answer:
please give me brainlist and follow
Explanation:
Normally, the flexible, round red blood cells move easily through blood vessels. In sickle cell anemia, the red blood are shaped like sickles or crescent moons. These rigid, sticky cells can get stuck in small blood vessels, which can slow or block blood flow and oxygen to parts of the body.

Which of the following is NOT an example of natural selection?
A. Plants with thorns are less likely to be eaten by herbivores than other members of the same species that lack thorns.
B. Bacterial populations in hospitals develop resistance to drugs used to combat infection by them.
C. Scientists breed cows that give greater amounts of milk than their ancestors.
D. Fruit fly larvae with an enzyme to break down alcohol are better able to feed on fermenting fruit than those that lack the enzyme.
Answer:
The correct answer would be - C. Scientists breed cows that give greater amounts of milk than their ancestors
Explanation:
Natural selection is the process of adapting according to the new changes in condition and change accordingly to survive. So the individuals of organisms that are better and adapt faster to survive and reproduce better than others are the result of natural selection.
Plants developed thorns so they can be avoided by predators is the adaption and example of natural selection. Similarly, bacterial populations adapt and develop resistance to the drug. Fruit fly larva developed and adapt as well. Breeding cows for more amount of milk than ancestors by scientists is not natural selection.
How is your body temperature held constant?
The elasticity of those capillaries plays a central role in our ability to maintain constant body temperatures. When there's too much heat in the body, our capillaries automatically expand and increase the blood flow to the skin, allowing the excess heat to transfer to the air.

9. The process of mitosis produces a new copy of an organism's genetic information.
10. Two new molecules of DNA are created
Explanation:
Through this replication process two complete molecules of DNA are created from one DNA molecule, with a double helix structure. This event is important for every organism in order for they to grow, reproduce and repair.
There are many proteins and enzymes that take part in all these steps.
The correct order of DNA replication is:
1. Cell replication starts into the mitosis phase of the cell cycle.
2. Helicase begins to break the hydrogen bonds between nitrogen bases.
3. The double coiled shape of DNA is called a double helix.
4. DNA polymerase attaches the free-floating nucleotides to the exposed nitrogen bases.

A canyon is a small, deep valley with cliff-like sides. The Spanish word caon, which meaning “tube” or “pipe,” is where the term “canyon” originates. Thus, option A is correct.
What Canyons type of land features represented?A deep valley that has been carved into the surface of the earth over a long period of time by erosion from a flowing river is referred to as a canyon.
It is also referred to as a gorge and typically features rocky cliffs and very steep walls. One of the most well-known instances is the Grand Canyon, which the Colorado River carved out.
Canyon: A deep valley with steep walls and a V-shape created by a river slicing through hard rock. These valleys are common in the upper reaches of rivers, where the stream's fast, strong current rapidly digs the valley. Gorges are smaller valleys with a similar aspect.
Therefore, Although “gorge” is frequently used interchangeably with “canyon,” a gorge is nearly invariably narrower and steeper.

The correct answer is Decreased biodiversity and decreased sustainability.
Weak sustainability is a concept inside environmental economics that states that 'human capital' can substitute 'herbal capital'. It is primarily based totally upon the paintings of Nobel Laureate Robert Solow, and John Hartwick.
Biodiversity loss refers back to the decline or disappearance of organic diversity, understood because of the style of residing matters that inhabit the planet, its distinctive ranges of the organic corporation, and their respective genetic variability, in addition to the herbal styles found in ecosystems.
What is an ecosystem?An environment is a geographic region wherein plants, animals, and different organisms, in addition to climate and landscape, paintings collectively shape a bubble of life. Ecosystems incorporate biotic or residing, parts, in addition to abiotic elements, or nonliving parts. Biotic elements consist of plants, animals, and different organisms although related, sustainable improvement and sustainability are distinctive concepts.
Hence clear that Decreased biodiversity and decreased sustainability are correct.
