True or falseThe study of where organisms live and how they got to specific places is called Biodiversity .
Answer:
False
Explanation:
Correct answer is biogeography
Explanation:
Biodiversity is a term used to describe the enormous variety of life on Earth. It can be used more specifically to refer to all of the species in one region or ecosystem. Biodiversity refers to every living thing, including plants, bacteria, animals, and humans.The series of diagrams below represents a process carried out by a unicellular organism. This process is know as
Phagocytosis is a crucial mechanism by which cells engulf and absorb foreign substances. This method is how small, unicellular organisms like free-living amoebas obtain food. Thus, option B is correct.
What phagocytosis process carries by unicellular organism?Phagocytes, a type of living cell, devour or engulf other cells or particles through a process known as phagocytosis. An amoeba or other free-living single cell could make up the phagocyte, or it could be one of the body's cells, like a white blood cell.
In unicellular creatures, phagocytosis is a critical mechanism for nourishment; in multicellular organisms, it is a function of specialized cells called phagocytes.
Therefore, Phagocytosis is a process used by some single-celled protists, such as amoebae, to absorb food particles.

The image below represents two waves X and Y, traveling to the same medium at the same speed how are the two waves different?
Answer: D is right
Explanation: It seems both waves have same wavelength.
Because speed = wavelength · frequency (v = λf) and
f = v/λ, so frequency is same. Because period T = 1/ frequency, also periods are same. Wave Y has higher amplidude and its energy is greater.
Answer:
D

Why is the genetic code common to all organisms!
Answer:
Why Is DNA Considered a Universal Genetic Code? DNA is considered a universal genetic code because every known living organism has genes made of DNA. ... All organisms also use DNA to transcribe RNA, and then they translate that RNA into proteins. Every living organism uses that same system.
Explanation:
The genetic code is universal because it is the same among all organisms. Replication is the process of copying a molecule of DNA. Transcription is the process of converting a specific sequence of DNA into RNA.
Protein-encoding genes specify the sequences of amino acids, which are the building blocks of proteins. In turn, proteins are responsible for orchestrating nearly every function of the cell. Both protein-encoding genes and the proteins that are their gene products are absolutely essential to life as we know it.
If a man has type B blood and his sister has type A blood, which combination listed below is most likely the genotypes of their parents?
Answer:
type AB father and type O mother
hope this helps! :D
The genotypes of the parents are type AB father and type O mother.
How is the blood type of a child determined?Each parent contributes to one of the two alleles to their child. A mother with blood type O can only pass allele O to her child. A father with type AB can pass either the A or B allele to the child. So the child can either have a genotype as AO or BO giving the child either A blood group or B blood group.
There are mainly eight blood genotypes. The blood types are determined by the location of A and B antigens and the presence of a protein called Rh factor.
Individuals with type O blood have no antigens attached to the cell surface of RBCs. It contains A and B antigens in the plasma portion of the blood. O blood type is needed the most for blood transfusion and blood donations.

Name the two types of leucocytes that are phagocytic.
NO SPAM PLS ...
Answer:
In humans, and in vertebrates generally, the most-effective phagocytic cells are two kinds of white blood cells: the macrophages (large phagocytic cells) and the neutrophils (a type of granulocyte).
In the blood, two types of white blood cells, neutrophilic leukocytes (microphages) and monocytes (macrophages), are phagocytic. Neutrophils are small, granular leukocytes that quickly appear at the site of a wound and ingest bacteria.

Alina notices that when she shines a desk lamp on a mirror, nothing happens.When she shines an infrared lamp on the mirror, the mirror starts to get warmer.Why does light from the infrared lamp warm the mirror when light from the desk lamp does not?
Answer:
Because the infrared lamp gives off a type of light that the desk lamp does not, and the mirror can only take in the energy from the infrared light.
Explanation:
Answer:
Explanation:
Infrared is used for incubators when a chicken egg is about to hatch. It is the electrical frequency of electromagnetic radiation the provides heat.
Because heat is produced electrically it can be controlled with something resembling a dimmer switch (the kind of switch that dims lights in romantic restaurants). That means that the temperature can be set to the hen's body temperature.
Infrared is just below visible light.

A mayflies that are part of the trout's diet
B. eels that compete with the trout for food
C. birds that use the trout as a source of food
D. fish that lay eggs that are eaten by the trout
Answer:
C. birds that use the trout as a source of food
Explanation:
Living organisms feed on one another in their natural environment in order to obtain energy for their various activities. According to this question, overfishing by humans decreases the population of trout living in a particular river.
This means that in that aquatic ecosystem (river), the population of organisms that feed on trout as a source of energy will also decrease. In this case, it is the birds. Hence, birds that use the trout as a source of food.
Answer:C
Explanation:
Because birds use that as a source of food.
