tRNA( Transfer RNA) molecules carry amino acids to the site of protein synthesis
Explanation:
Proteins are the building blocks of the cells. The process of protein synthesis involves transcription and translation of the genetic information stored in the DNA. After the process of transcription which is the process to get RNA molecules from the DNA. After this process, during protein synthesis tRNA carries amino acids to the ribosomes is the structure where protein synthesis takes place.
Answer:
The correct answer is thematic map.
Explanation:
A kind of map, which gives importance to a specific data set or topic is known as a thematic map. It demonstrates the distribution or population of specific organisms or elements, which is associated with a certain theme or geographical characteristic.
The thematic maps are of different kinds like proportional symbols, choropleth maps, dot maps, and others. The thematic map would most possibly be used to demonstrate the population density of Grizzly bear in Glacier National Park as thematic map helps in showing population.
A "Thematic" map is a type of map specifically designed to show a particular theme connected with a specific geographical area, The answer to your question is a Thematic map.
can hear, so the owner knows his genotype is either DD or Dd. If the dog's genotype is
Dd, the owner does not wish to use him for breeding so that the deafness gene will not
be passed on. This can be tested by breeding the dog to a deaf female (dd). Draw the
Punnett squares to illustrate these two possible crosses. In each case, what
percentage/how many of the offspring would be expected to be hearing? deaf? How
could you tell the genotype of this male dog? Also, using Punnett square(s), show how
two hearing dogs could produce deaf offspring.
Answer:
50% with DD X dd / 50% with Dd x dd
Answer:
Petri dishes are widely used in biology to cultivate microorganisms such as bacteria, yeasts, and molds.
Explanation:
It is most suited for organisms that thrive on a solid or semisolid surface.
Answer:
The cones detect the brightness and the rods the colors.
Explanation:
Thanks to a layer of photoreceptors inside the eye, it is able to convert the captured light into brain signals.
There are two types of photoreceptors: rods and cones.
b)growth factors
c)the mitotic spindle
d)cancer cells
Answer:
a) Cyclins
Explanation:
The internal regulators of the cell cycle are cyclins and CDK (cyclin-dependent kinase). These are proteins that regulate the cell cycle in different checkpoints.
The cyclin proteins stimulate another kind of protein i.e. CDK, which helps in the entry and exit of cells in different checkpoints. The checkpoints are G1, S, and G2 phases. Without this protein regulation the cell cycle can't run properly, nondisjunction of chromosomes, and cancer may result.
The growth factors help in the migration of cells in different parts of the body. This causes cellular growth. These include hormones and enzymes.
Mitotic spindle/spindle fibers separate the double number of chromosomes and put them equally in 2 daughter cells. During the cell cycle, the spindle fibers are not active. It is active in cell division.
Cancer cells are uncontrolled growth of cells. This results due to the failure of cell cycle regulators. Thus cells divide rapidly.
Answer:
Gas, solid and liquid.
Explanation:
The matter exist in its well defined state. Three main states of matter are solid, liquid and gas. Different matters exist among three states in this universe.
Th solid particles are tightly packed together and has little space between them. The gases particles are far away from each other. The liquid particles are less closely packed together than solid but less than gases. Gases has highest space between them and can move easily, then liquid and least speed is of solid particles.
Thus, the answer is gas, solid and liquid.
