Answer:
Multicellular organism is the example of complexity of the natural world.
Explanation:
Multicellular organism such as human which is made of billions of cell. Each cell perform a specific function. The function of one organ is different from the other organ. For example, brain of human is made of millions of neurons which takes instructions from brain to the organs and bring messages from organs to the nervous system in the form of electrical impulses. In short every system in our body is full of complexity.

Leaf cells have more chloroplasts than cells in other parts of the plant
Answer:
Chloroplasts are organelles that conduct photosynthesis, where the photosynthetic pigment chlorophyll captures the energy from sunlight, converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in plant and algal cells. They then use the ATP and NADPH to make organic molecules from carbon dioxide in a process known as the Calvin cycle. Chloroplasts carry out a number of other functions, including fatty acid synthesis, much amino acid synthesis, and the immune response in plants. The number of chloroplasts per cell varies from one, in unicellular algae, up to 100 in plants like Arabidopsis and wheat.

Which is the result of genetic drift?
A) increase in the size of the gene pool
B) a decrease in genetic diversity
C) an increase in total allelic frequency
D) decrease in the size of the population
Answer:
B.)
Explanation:
Although genetic drifts can change allelic frequencies, it doesn't specifically increase it. It does not increase in the size of the gene pool nor does it cause a decrease in the size of the population. B is correct.
The result of genetic drift is a decrease in genetic diversity.
What is genetic diversity and its example?Genetic diversity is defined as genetic variability present within species. E.g. Different breeds of dogs, different varieties of rose flower, wheat, rice, mangoes, etc.
Thus, option "B" is correct.

In organ transplants, the body recognizes that the new organ is made of foreign cells. What kind of medicine would you give a patient to increase the chances of transplant success?
Answer:
immunosuppressant
Explanation:
After an organ transplant, you will need to take immunosuppressant (anti-rejection) drugs. These drugs help prevent your immune system from attacking ("rejecting") the donor organ. Typically, they must be taken for the lifetime of your transplanted organ.
All cells reproduce to make new cells. However, stem cells actually form many different types of cells. Adult stem cells can also repair tissues in the body.
White blood cells protect against _____ and aid in blood clotting when injuries are sustained
Answer:
pathogens
Explanation:
White blood cells also known as leukocyte does not have hemoglobin. However, it is capable of defending the body against any kind of infection and disease caused by foreign biotic and abiotic elements or pathogens by producing antibodies against them.
Kono Dio Da!!!!
White blood cells protect against pathogens and aid in blood clotting when injuries are sustained. a particular sort of blood cell that is produced in the bone marrow and present in both the blood and lymphatic tissue.
What is the role of White blood cells?The immune system of the body includes white blood cells. They support the body's defenses against illness and infection.
Innate immunological processes carried out by leukocytes, specifically monocytes, macrophages, and neutrophils, interact with the hemostatic system to express and release coagulation and fibrinolytic factors.
The job of protecting wounds is performed by a different class of blood cells known as a macrophage, a sort of white blood cell.
Therefore, this cell controls the healing process and fights infection.

Explanation:
Butterflies usually are identified by the colors and patterns on their wings. Butterflies have four wings: The two wings near the butterfly’s head are “forewings” while the wings near the butterfly’s tail are “hindwings.” You can use the following dichotomous key to identify four common butterfly species in North America.
The shown butterfly in the diagram is - Papilio polyxenes.
Butterflies usually are identified by the colors and patterns on their wings. To identify an organism using a dichotomous key, compare the organism’s traits to the first pair of descriptive statements on the key.
Follow the directions after each matching statement until you get to the organism’s identity.The points on the hindwings identify the butterfly as
a swallowtail butterfly is either Papilio glaucus or Papilio polyxenes.1. Hindwings rounded ………………… Goto 3
2. Wings mainly yellow …………… Papilio glaucus
Wings mainly black ………….. Papilio polyxenes
3. Wings orange with black piping…Danaus plexippus
Wings yellow with black edges….. Colias philodice
The wings are mainly black, so the butterfly is Papilio Polyxenes (common black swallowtail)Thus, the shown butterfly in the diagram is - Papilio polyxenes.

Explain how the superbug was created.
Answer:
A superbug refers to a germ that has formed resistance to multiple drugs that once treated the infection caused by the germ. The term “superbug” was developed by the media. While any germ may become a superbug, bacterial and fungal strains that routinely infect humans, animals, and crops are most likely to do so.
Superbugs are strains of bacteria that are resistant to several types of antibiotics. ... And the overuse and misuse of antibiotics helps to create drug-resistant bacteria. Here's how that might happen. When used properly, antibiotics can help destroy disease-causing bacteria.

A. Some inherited genetic mutations can be good for the offspring.
B. Different genetic mutations cause few forms of cancer.
C. Somatic mutations can be inherited from parents or acquired during life.
D.Genetic mutations that cause diseases are always passed on to offspring.
Answer:
A genetic mutation is a random change in the DNA that is passed on further generations of cells and or organisms. Genetic mutations are accidental changes in the DNA in the germ cells or early in the formation of the embryo.
Explanation:
Some inherited genetic mutations can be good for the offspring.
What is mutation?"It is a change in the structure of a gene."Gene is a structural and functional unit of hereditary.It is caused due to addition, deletion or copying of single base pairs of DNA.The mutation that occurs in somatic cells (cell other than stem cells or s ex cells) are not transferred from parent to offspring.A mutation should occur in s ex cell, in order for it to pass down to the offspring. So, the mutation that cause disease if occurs in somatic cell will not be passed to the offspring.The mutation can sometime result in the production of new proteins that are beneficial in nature.Not all the genetic mutation can cause cancer.Hence, the correct option is A. Some inherited genetic mutations can be good for the offspring.
