1. What is a limiting factor in relation to an ecosystem
2. What does carrying capacity men for a population?
Answer:
1 A limiting factor is anything that constrains a population's size and slows or stops it from growing. Some examples of limiting factors are biotic, like food, mates, and competition with other organisms for resources. ... Limiting factors are usually expressed as a lack of a particular resource.
2 Carrying capacity can be defined as a species' average population size in a particular habitat. ... If these needs are not met, the population will decrease until the resource rebounds. Explore carrying capacity with these curated classroom resources.
Hope this is fine for youThe 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.

D

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.

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.

In humans, widow's peak (A) is dominant over a continuous hairline (a), and short fingers (B) are dominant over long fingers (b). Two individuals with widow's peak and short fingers have a child with continuous hairline and long fingers. Determine the genotypes of the parents.
Answer:
Both parents are heterozygous for the traits and exhibit the dominant phenotype → AaBb
Explanation:
Available data:
widow's peak (A) is dominant over a continuous hairline (a)short fingers (B) are dominant over long fingers (b)Cross: Two individuals with widow's peak and short fingersF1) a child with continuous hairline and long fingersGenotypes Phenotypes

Parentals) A-B- x A-B-
Note: the - symbol represents either a dominant or recessive allele.
F1) child with continuous hairline and long fingers → aabb
Each parent provided one allele for each trait to the child. So the child inherited one recessive allele a and one recessive allele b from EACH parent. The fact that both parents could provide one recessive allele to the child for each character, indicates that both parents are heterozygous for the trait. It is the only way of having a child who expresses the double recessive trait.
Parentals genotypes → AaBb x AaBbChild → aabbWithin food chains, matter is ___
• always recycled from one chemical form into another
• constantly increasing
• constantly decreasing
• always changing from one element to another

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.

Why did the timber industry do so well in the 1990s?
Answer:
A lot of technology improved production. There were no laws restricting harvesting timber. The economy was good and housing was in high demand. The United States was the only country that exported timber.

Answer:
The economy was good and housing was in high demand.
Explanation:
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.

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.
