Answer:

Cell wall, chloroplast, vacuole. Plant cells have a cell wall, chloroplasts and other specialized plastids, and a large central vacuole, whereas animal cells do not.

Explanation:

The main difference between plant cells and animal cells are cell wall and chloroplast , whereas for the vacuole plants have a vacuole called vescile which is not the same as the vacuole in plant cells.

Vacuoles are very large as they are needed to store water and they mostly contain water and sugars . On the other hand, vesicles are small and contain water, nutrients, enzymes, wastes, solution of water or food etc. This is the key difference between vacuoles and vesicles. hope it helps :)

Hemoglobin is a protein in red blood cells that carries oxygen. The hemoglobin test measures how much hemoglobin is in your blood. Hemoglobin is the most important component of red blood cells. It is composed of a protein called heme, which binds oxygen.

If some mice have inherited a genetic mutation that causes them to have a band of white fur around the middle of their bodies, it is most likely that an ancestor of these mice also had the same genetic mutation that caused the band of white fur.

Genetic mutations are changes in DNA sequence that can be inherited by offspring from their parents. If a mutation passed down from the parent to its offspring, then next generations will also have the same mutations. The white fur band presence suggests that the mutation for this trait has been inherited through multiple generations of mice.

1) One seismogram represents the distance to the epicenter (indicated by one circle). This is determined by the arrival times of the P and S waves. When the seismograph is near to a quake, the S-waves arrive shortly after the P-waves.

2) A single or double recording station could only measure distance, not direction; a full circle is drawn around the station to allow for all possibilities.

3) Triangulation is a technique used by scientists to determine the location of an earthquake's epicenter. When seismic data is collected from at least three different locations, the epicenter may be established by where the data links. A network of seismographs positioned in various directions records every earthquake.

4) A seismograph is a device used to record seismic waves caused by an earthquake, explosion, or another Earth-shaking event.

5) In the aftermath of an earthquake, the P waves go ahead of the S waves. As a result, the longer the time difference between the arrival of the P and S waves, the greater the distance between a seismic recording station and the earthquake epicenter.

6) Surface waves frequently induce more ground motion than body waves and hence cause more harm.

Seismometers are measuring instruments that detect ground noises and vibrations caused by earthquakes, volcanic eruptions, and explosions. Seismographs usually consist of a seismograph, a timing device, and a recording device.

Modern seismometers are capable of detecting ground movements as small as a few nanometres - a millionth of a millimeter. The magnitude of the earthquake is calculated using the measured amplitudes and its closeness to the hypocenter.

Chromosomes are tightly wound strands of DNA located in cells. The correct answer is A.

Chromosomes are structures found within cells that contain genetic material, which is DNA (deoxyribonucleic acid). DNA is the fundamental molecule that carries the genetic instructions for the development, functioning, and reproduction of living organisms.

Chromosomes consist of long, linear DNA molecules that are tightly coiled and condensed around proteins called histones. This coiling and condensing of DNA into chromosomes allows it to be efficiently packaged and organized within the nucleus of the cell.

The DNA molecule itself is a double helix composed of two complementary strands, made up of nucleotide building blocks. Each nucleotide consists of a sugar molecule, a phosphate group, and one of four nitrogenous bases (adenine, thymine, cytosine, or guanine).

Genes, which are functional units of heredity, are segments of DNA located on chromosomes. They contain instructions for building and maintaining the structure of proteins, which are essential for various biological processes in the body.

In summary, chromosomes are structures composed of tightly wound DNA molecules that store and transmit genetic information. DNA, on the other hand, is the chemical molecule that makes up the genetic material and is organized into chromosomes within cells. Therefore, the correct answer is A.

An example of a base is sodium hydroxide. In this case option C is correct

What are bases?

a substance with the ability to absorb hydrogen ions from water and neutralize acids in chemistry. The skin may feel slippery or soapy when exposed to bases, which can turn some colors blue. A base is best represented by sodium hydroxide.

Acids are defined as substances that contain hydrogen and have the capacity to donate a proton (hydrogen ion) to another chemical. Any molecule or ion that can absorb the hydrogen ion from an acid is known as a base. Usually, acidic chemicals can be distinguished by their sour tastes. Having more positively charged hydroniums than negatively charged hydroxyls indicates that the substance is acidic. In an aqueous solution, bases are a category of chemical that emit hydroxide (OH-) ions, accept protons, or give away electrons.

Human-induced global warming using today's technology can be thought of as a geologically temporary phenomenon because the carbon dioxide (CO₂) emissions from human activities, such as burning fossil fuels, are being released into the atmosphere at a much faster rate than natural processes can remove them.

Global warming is the long-term warming of the Earth's surface that has been seen since the pre-industrial era and is attributed to human activity, particularly the burning of fossil fuels, which raises the levels of heat-trapping greenhouse gases in the atmosphere.

Environmental changes brought on by global warming may have a negative influence on human health. Additionally, it can result in an increase in sea level, which poses a threat to biodiversity, a change in precipitation patterns, an increase in the likelihood of droughts and floods, and the loss of coastal land.

Answer: Shallow and spread out roots

Explanation: They will spread out and go down to become strong roots

The frequency of the recessive allele would be 0.55, that of the dominant allele would be 0.45, and that of the heterozygous individuals would be 0.495

Recall that for a population in Hardy-Weinberg equilibrium:

p2 + 2pq + q2 = 1

Also, p + q = 1

Where:

p = frequency of the dominant allele in the population

q = frequency of the recessive allele in the population

p2 = percentage of homzygous dominant individuals

q2 = percentage of homzygous recessive individuals

2pq = percentage of heterozygous individuals

In this case, the percentage of homzygous recessive individuals can be calculated as:

Homzygous recessive = those that could not taste PTC = 65/215

q2 = 65/215 = 0.302

    q = 0.55

Since p + q = 1

           p = 1 - 0.55

                   = 0.45

The frequency of the heterozygous individuals = 2pq

                      = 2 x 0.45 x 0.55

                        = 0.495
