Letter Q and letter S are responsible for creating and delivering nutrients throughout the cell.
D
Letter U and letter R are involved with the processes of transcription and translation for the cell.
Answer:
B) letter T and letter R store the genetic material necessary for replication of the cell
T-nucleus and R-mitochondria
The statement that correctly describes an interaction between organelles is : ( D ) Letter U and Letter R are involved with the processes of transcription and translation for the cell.
Letter U represents the Nucleus of the plant cell model attached while the Letter R represents the cytoplasm of the cell model.
The nucleus of a cell contains the genetic material ( DNA ) of the cell while the cytoplasm fills up the cell and is enclosed by the plasma cell membrane of the cell. Transcription involves the synthesis of RNA from a DNA template contained in the Nucleus and this process involves, The nucleus and cytoplasm of a cell.
Hence we can conclude that The statement that correctly describes an interaction between organelles is : ( D ) Letter U and Letter R are involved with the processes of transcription and translation for the cell.

Light-skinned people generally have a greater proportion of which pigment in their skin?
Keratin
Pheomelanin
Eumelanin
Carotene
Answer:
Pheomelanin
Explanation:
Dark-skinned individuals produce more melanin than those with pale skin.
Light-skinned people typically have a greater proportion of pigment in their skin Pheomelanin, Dark-skinned persons produce more melanin than those with pale skin.Thus, option "B" is correct
What is the difference between pheomelanin and eumelanin?
Eumelanin is black or brown tint and pheomelanin is red or yellow pigment.
Individual who create lots of pheomelanin tend to have lighter skin, often because of freckling.
Freckles occur when melanocytes clump together. Melanocytes are generally scattered rather evenly in the skin.
Thus, option "B" is correct, Dark-skinned individuals produce more melanin than those with pale skin.

Answer:
Water puts pressure depends on their amount.
Explanation:
On the left side, there is less quantity of water in the tube that put less pressure on the bag present at the bottom and the bag swells slightly while on the other hand, on the right side, there is more amount of water in the tube that puts large pressure on the bag located at the bottom and as a result it swells higher than the other bag so we can conclude that more water puts more pressure and less water puts less pressure.
What will most likely happen if all the chloroplasts are removed from a plant cell?
What’s the answer to this pls
We’re you able to place some events within the periodic table with just a single clue
Explanation:
is that a personal question, or on a quiz or something?
1. What effect does air pressure have on wind movement?
2. What happens to the density of air as it is heated?
3. It’s a hot, sunny morning in a coastal town in South Florida. Warm air is rising up from the land. Large, puffy clouds are forming overhead. Which way do you think the wind will be moving this afternoon, and what do you think will happen to the temperature?
Answer:
1. The lower the air pressure the faster the wind the higher the air pressure the slower the winds
2. When the heat of the air increases the density of the air decreases.
3. The air above the ocean will, therefore, be warmer and of low pressure than that over land which will be cooler and of relatively higher pressure. Winds will, therefore, blow seawards because winds blow from high to low-pressure systems.
Explanation:
A student prepares a cell homogenate from spinach leaves. She performs a cell fractionation experiment to determine the shortest amount time of centrifugation at 2000xg that will yield the highest percentage of chloroplasts in the pellet fraction. She splits the spinach homogenate into 5 equal parts and centrifuges the parts at 2000xg for 0, 5, 10, 15 or 20 min. She then determines the proportion of chloroplasts in the supernatant and pellet fractions. The controlled variable(s) in the student's experiment is/are:_____.
a. proportion of chloroplasts in each fraction.
b. use of same plant homogenate throughout.
c. time of centrifugation in minutes.
d. g-force of centrifugation.
Answer:
b. use of same plant homogenate throughout.
Explanation:
In an experiment, the controlled variable, also called the CONSTANT is the variable that is kept the same throughout the course of the experiment in order not to influence the result or outcome of the experiment.
In this question, a student performs a cell fractionation experiment to determine the shortest amount time of centrifugation (manipulated variable) at 2000xg that will yield the highest percentage of chloroplasts (responding variable) in the pellet fraction. In this experiment, the variable being controlled is same spinach plant homogenate used throughout.

Answer:
True
Explanation:
Answer:
true
Explanation:
The statement "carrying capacity can vary depending on environmental conditions" is true. Carry capacity is defined as the maximum population size of a species that an environment can sustain indefinitely. It is also defined as the environment's maximal load of a species. Factors that impact on the carrying capacity of a species are the availability of food and water, raw materials to build shelter, the environment's ability to process waste products, as well as the species' ability to reproduce.

If you were to start at the base of a mountain and climb it all the way to the top, how would the climate change?
A The climate would get colder and drier as you go up the mountain.
B The climate would get warmer and wetter as you go up the mountain.
C The climate would stay the same because you are in the same climate zone.
D The climate would be similar to a tropical climate zone as you go up the mountain.
The climate would get colder and drier as we go up the mountain. So, the correct option is A.
What is the effect of altitude on the atmosphere?When altitude increases, the amount of gas molecules in the air decreases, so the air becomes less dense than air closer to sea level, which is what meteorologists and climbers mean by "thin air". Thinner air exerts less pressure than air at lower altitudes.
Most of the gas molecules in the atmosphere are pulled closer to the Earth's surface by gravity, so gas particles are denser near the surface, so with more gas particles in a given volume, there are more collisions of particles and therefore more pressure.
Thus, the climate would get colder and drier as we go up the mountain. So, the correct option is A.

Explanation:
A pure-breeding, tall pea plant with white flowers is crossed with a pure-breeding, short plant with red flowers. The F1 plants are tall, with red flowers. When allowed to fertilize themselves, these produce the following F2: 326 tall, red; 104 tall, white; 117 short, red; and 29 short, white. You are conducting a Chi-Square analysis and what is the null hypothesis?
Answer:
Null Hypothesis -
The observed frequency is approximately equal to the expected frequency of phenotype.
Explanation:
Pure Breeding Cross - TTww x ttWW
Genotype of offspring in F2 generation - TtWw
Null Hypothesis -
The observed frequency is approximately equal to the expected frequency of phenotype.
The chi square analysis is attached
The degree of freedom for this question is 3
The p value for X^2 estimated through chi square test is 0.5
Hence the null hypothesis is accepted.
The ability to taste the chemical PTC is determined by a single gene in humans with the ability to taste given by the dominant allele T and the inability to taste by the recessive allele t. Suppose two heterozygous tasters (Tt) have a large family. What is the likelihood that their first child will be a taster
Answer:
75%
Explanation:
This question involves a single gene coding for the ability to taste the chemical PTC. The allele coding for the ability to taste (T) is dominant over the allele coding for the inability to taste (t). This means that an heterozygous individual will have the ability to taste PTC.
According to this question, if two heterozygous tasters (Tt) cross to have a large family i.e. Tt × Tt, the following gametes will be produced by each parent;
Tt = T and t
Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
TT, Tt, Tt - Tasters (3/4 or 75%)
tt - Non-taster (1/4 or 25%)
Note that based on the question asked, there is a 75% probability that their first child will be a taster because there is equal segregation of alleles into gametes.
