Answer:

She is using a karyotype

Explanation:

A karyotype is an image that helps in analysis to a person's chromosome. It is a picture of all chromosomes of an individual. Scientists take this picture or image sample of chromosomes of the individual is isolated, stained or examined under the microscope. This image helps in analysis and study of the chromosome.

Explanation:

Lipids are the class of biomolecule in the table. Thus option C is correct.

Biomolecules are major building blocks of all living organisms which includes Carbohydrates, Proteins, Fats, Nucleic Acids and the basic components are carbon, hydrogen and oxygen atom.

Carbohydrates are polyhydroxy aldehydes or ketones collectively called as saccharides  or sugar; It can be up different types monosaccharide, oligosaccharide and polysaccharides based on composition of number of sugar molecule.

Proteins are polymers of amino acids which are joined by peptide bond and form polypeptide, can be classified as primary, secondary, tertiary and quaternary protein.

Nucleic acids are the carrier of genetic material can be up two types such as  deoxyribonucleic acid (DNA) and ribonucleic acid (RNA), made up of nitrogenous base, sugar and phosphate.

Lipids are organic water insoluble biomolecule related to fatty acids, they include sterols, mono-, di- or triglycerides, phospholipids, etc.

Thus option C is correct.

Answer:

(2) acting as natural selecting agent

Explanation:

Compounds like the pesticide DDT may bring about the evolution of new strains of organisms by acting as a natural selecting agent.

Evolution is generally defined as a gradual change to the characteristics of organisms over a period of time.

When DDT is used on a particular population of pest, those that are weak within the population die off, leaving only those that are strong within the population to survive and multiply. The DDT acts a selecting agent for the survival gene in the pest and the survived gene eventually evolve into a new, DDT-resistant strain pest in no time.

The correct option is option (2).

Answer:

This is because vestigial parts are usually homologous to most of the structures that are functional in other species of organisms. E.g.. the Vestigial legs which are non functional in  whale and Dolphins, are useful to other organisms. Hence, if these organisms possessed these structures, they should share certain characteristics with  each other.Therefore these organisms can be said to evolved from one another.Thus their vestigial organism should be included by the author  as evidence of evolution.

Answer:

Rafflesia arnoldii is a tropical plant with a huge blood-red flower, which emits heat and emits the smell of decomposed meat. What use are these adaptations to this plant

Explanation:

The smell is adaptation for pollination.This is because it attracts insects which carry on the process of pollination.

Its possible Endothermy characteristic  is for mimicry Its releases  heat to attract  the pollinators- blowflies.The endothermic mechanism  is well pronounced during flora development: which further buttress the fact that this  is related to pollination to attract blowflies, and not to thermoregulation.

Explanation:

Answer:Cells use fat and starch for long term energy storage instead of ATP molecules because it is hard to breakdown fat in a very short time while ATP can be broken down in a very short time. ATP is mainly used while doing short bursts of exercises. Fats have a very strong bond of molecular chains and this makes it hard to breakdown quickly.

Explanation:

Answer:

ATP is used for short-term energy and to build molecules of starch and fat.

Answer:

These woolly mammoths were not closely related to mastodons. Mammoths and mastodons may have once roamed the Earth together, but they represent two distinct species of the Proboscidean family. ... Mammoths and modern elephants are closely related members of the same family (Elephantidae).

Explanation:

No, they are not the same species.

Despite the superficial resemblance, mastodons were distinct from mammoths. Mastodons were shorter and stockier than mammoths with shorter, straighter tusks. Mastodons were wood browsers and their molars have pointed cones specially adapted for eating woody browse.

While mastodons look a lot like modern elephants, they are not closely related. The ancestors of modern elephants and mammoths went their separate ways about 5 million years ago, and mastodons branched off even earlier, about 25 million years ago.

The given organic molecule is the structure of propene. The given molecule has a single double bond. Hence, Option B is the correct answer to the statement.

The organic molecule nomenclature is determined by the presence of a single bond, double bond, or triple bond. The functional group has an important role too.

The single carbon is called mono. if two carbons are present, the compound is called di. if three carbons are present, the compound is called prop. In the given molecule, there are three carbons.

If a single bond is present, that bond is called "ane." If a double is present, it is called "ene". "Yne" is called when three bonds or triple bonds are present. By combining the carbon number and the bond, the nomenclature is complete. Here, three carbon molecules are present with a double bond; hence, it is called propene.

Hence, the correct answer is option B, which is propene.

Answer:

Parasitism

Explanation:

First, let's define each term.

Mutualism: A symbiotic relationship where both organisms benefit

Commensalism: An association where one organism benefits, and the other is not harmed or benefited.

Neutralism: 2 organism interact but they have no effect on each other.

Parasitism: A symbiotic relationship where a parasite lives in or on another organism and harms the organism.

A dog and a tick are an example of parasitism. The tick lives on the dog and drinks the dog's blood. This is the food for the tick, so the tick is benefiting by gaining a food source. The dog can be harmed if the tick is carrying a disease, such as Lyme disease.

Answer:

C. By causing auxin to migrate in to the shaded portion

Explanation:

Auxin is the most important plant hormone involved in the apical growth of plant parts. Auxin is evenly distributed in a plant with a normal light condition, however, when a particular part of a plant is exposed to sunlight, that illuminated part contains less auxin. The hormone is transported to the shady part of the plant via diffusion.

This causes more auxin to be present in the shady part than the illuminated part, hence, the shady part experiences a faster and elongated growth. This elongated growth in the shaded portion of the plant causes it to grow towards the direction of the light, a process called PHOTOTROPISM.

Answer:

Professor and climate change activist Tim Flannery believes that massive farms of seaweed, a crop with enormous carbon sequestration capabilities, could potentially draw enough carbon dioxide from the atmosphere in a short enough time frame to mitigate some of the worst effects of climate change. Flannery acknowledges that his radical approach could raise some negative externalities, and sweeping carbon under the ocean isn’t a permanent solution. But for those who worry that the climate crisis is a lost cause, he offers reassurance that climate change is a soluble issue.

As a cell becomes larger, its volume stays the same in relation to its surface area. So the correct option is A.

There are two types of cell division. These are mitosis and meiosis. Most of the time when people talk about cell division, they are referring to mitosis. This is the process of the formation of new body cells. Meiosis is another kind of cell division that results in the formation of egg and sperm cells.

Mitosis is the fundamental process of life. During the process of mitosis, a cell duplicates itself along with all of its contents. This includes the chromosomes of the cells. Then the cell splits to form two identical daughter cells.

All the steps of mitosis are carefully controlled by certain genes because of the critical nature of this process. When mitosis is not being regulated correctly, various health problems such as cancer can arise.

Meiosis is the next type of cell division. This ensures that humans have the same number of chromosomes in each generation. Meiosis is a two-step process that reduces the chromosome number by half, from 46 to 23, to form sperm and egg cells. This is also called the reduction division.

Therefore the correct option is A.
