Answer:
Sickle cell anemia is a genetical disorder that occurs when both the alleles from both the parents in the offspring is recessive. If only one gene is recessive, then the person will not have the disease.
It is a disease in which the shape of the red blood cell alters from biconcave disc shape to sickle shaped because of the mutation in hemoglobin gene. It is a case of incomplete dominance in which for the disease to occur, both the genes have to be recessive.

A particular ant species has four pairs of chromosomes. Identify the genetic possibilities from independent assortment of a gamete.
Answer:
Here, no of pairs of chromosomes in ant = 4.
Now during the gametogenesis, each pair of chromosome will get separated in one gamete each.
So, number of unpaired chromosomes = 4 unpaired chromosomes.
The gametes are now haploid, i.e. Without paired chromosomes.
Now, only 1 of the one pair of chromosomes will be carried inside a gamete,
Lets assume, the gene present in the cell chromosomes is heterozygote
So, there will be 2 possibilities.
So, their probability will result as [tex]=2\times2= 4[/tex]possibilities.
Then for 4 chromosomes would be [tex]4^4=256[/tex] chromosomes.
Answer:
The total number of possibilities for four chromosomes would be 4^4 = 256 possibilities in the gamete or offspring.
Explanation:
Given,
Organism – Ant species
Number of chromosomes = 4 pairs
Genetic possibility due to independent assortment = ?
Solution:
During the gamete formation, only one chromosome from a pair foes to the gamete as meiosis occurs. Therefore, the gamete will have only 4 chromosomes instead of 4 pairs. The gamete can get any of the two chromosome from a pair and thus, it has 2X2 = 4 possibilities.
Therefore, total number of possibilities for four chromosomes would be 4^4 = 256 possibilities in the gamete or offspring.

What Made Albert Einstein Smart
Answer:
he was considered a genius because of his helpful contribution I science and math
Albert Einstein's intelligence stemmed from his deep curiosity, rigorous thought experiments, and the ability to challenge existing norms, which led him to revolutionize physics with his theory of relativity.
Explanation:What made Albert Einstein smart is a question that delves into various facets of his personality, his intellectual curiosity, and his approach to scientific inquiry. Einstein, renowned for his theory of relativity and as a symbol of high intellect, attributed his success not just to his intelligence but also to his persistent curiosity and the ability to question the obvious. Albert Einstein was not content with accepted norms and displayed an unparalleled dedication to understanding the mysteries of the universe.
From a young age, Einstein showed a proclivity for clear thinking and thought experiments ('Gedankenexperiment'), a method he employed to conceptualize and solve complex problems before they could be tested experimentally. His ingenious use of deductive reasoning and intuitive insight, coupled with his deep knowledge and experience, allowed him to challenge and eventually revolutionize modern physics with his theory of relativity.
Einstein's intellectual journey highlights the importance of not just raw intelligence, but a relentless pursuit of knowledge, a robust imagination, and a fearless approach to challenging the status quo. His legacy teaches us that brilliance is as much about the questions we dare to ask as it is about the answers we discover.

Answer:
Answer is B: The Removal Of Metabolic Wastes From Cell
Explanation:
Excretion is best described as the removal of metabolic wastes from cells
Excretion refers to the process by which metabolic wastes are removed from a cell or an organism. This can include undigested material from the digestive tract. It does not include processes such as cyclosis or dipeptide hydrolysis.
Explanation:Excretion is best described as the process by which metabolic wastes are eliminated from an organism. In simpler terms, excretion is the removal of metabolic wastes from a cell. These wastes could be products of cellular metabolism like carbon dioxide or urea. It can also pertain to the removal of undigested material from the digestive tract, like fiber that our body cannot digest.
However, it does not refer to the removal of toxic wastes by the process of cyclosis, or the removal of water molecules from dipeptide hydrolysis, as these processes are more specific and separate from the general process of excretion.

What is vegetative propagation?
Answer:
A type of asexual (only 1 organism needed in the process, only 1 parent) reproduction found in plants.
Explanation:
Vegetative propagation consists in the sharing of a stalk/root/other to form a new plant. So basically what happens is that a stalk/root/other from a parent plant is "left apart" so that a new organism can rise from it.
Some plants have parts that are used exclusively during vegetative propagation.

When a sea urchin egg is removed from the
ocean and placed in freshwater, the egg
swells and bursts. Which of these causes
water to enter the egg?
A) Coagulation
B) Sodium pump
C) Active transport
D) Osmosis
Answer:
Osmosis is always responsible for water crossing a membrane
Explanation:
What causes water to enter the egg and cause the egg to swell and burst is osmosis. Option D is correct.
Osmosis is a process that happens when the concentration of solute in one place is higher than in the other, this causes water to move towards the place with the higher concentration of solute in order to dissolve it. In this case. the situation would be:
The sea urchin egg is in the oceanThe ocean is salt water, so the egg contains water with salt in it (salt is a solute)The egg is placed in freshwater (meaning this water does not have salt)Because the water on the outside of the egg has no salt, the concentration of solute in the egg (salt), causes Osmosis to occur. Through Osmosis, water enters the egg until it swells and then bursts.Therefore, because the egg has more solute, Osmosis causes the water to enter the egg until it bursts.

Describe at least three of the water cycle processes you have learned about in the course
Answer:
Evaporation: Water evaporates from the ocean, from the earth's surface and also by organisms, in the phenomenon of perspiration in plants and sweating in animals. Living things, especially plants.
Condensation: Water in the form of steam rises and condenses forming clouds, formed drops of water.
Precipitation: It occurs when the drops of water, which form the clouds, cool, accelerating the condensation and joining the drops of water to form larger drops that eventually precipitate to the earth's surface. Precipitation can be snow or hail or rain
Explanation:
Answer:
Through the hydrologic cycle.
Explanation:
Water moves through the hydrologic cycle in three forms: solid, liquid or gas. When the sun shines on the Earth and it’s bodies of water during the day, a process called convection causes some liquid water to evaporate into the air in the gaseous state called vapor, binding with dust particles in the air to form clouds. When the water vapor in the atmosphere reaches the point of saturation, the air cools, water condenses back into a liquid and falls down to Earth in the form of precipitation. Approximately 10% of the water from precipitation is absorbed by plants. The rest of it either collects in oceans, lakes and rivers by runoff or it percolates through many layers of sand and rock underground in the earth’s surface, until it slowly makes its way into larger bodies of water by gravity. Plants use the water they absorb for photosynthesis. Humans, animals and insects absorb some of that water when they eat plants. In the heat of the sun, water once again gets from lakes and oceans back to atmosphere by evaporation, and the hydrologic cycle repeats again by water falling as precipitation.

The total number of gas particles in Earth’s atmos
Answer:
A. The air pressure in that section of Earth’s atmosphere decreased.
Explanation:
In the free air, the density of the air diminishes as the air is warmed. On increasing the pressure, the density also increases. The air is packed. The density increments as pressure increments.
The thickness and density of air decline with the increase of height because of that the surface area of the Earth's climate diminishes with increase in height, along these lines gas particles can spread out.
The density of the air is most minimal at a high rise on a hot day when the pressure of the atmosphere is low.

Answer:
Equilibrium
Explanation:
When the system is in equilibrium, this means there is no further change in the system because the opposing forces (forward & reverse), such as those in diffusion, are at balance and therefore there seems to be stability. Usually this is when the system is at its highest entropy of lowest Gibbs free energy.
It is possible to calculate the equilibrium constant of a reaction aA+bB⇋cC+dD
Kc = ([C]^c*[D]^d) /( [A]^a*[B]^b)
The term used to describe when molecules are even throughout a space is equilibrium.
When molecules are evenly distributed throughout a space, it is called equilibrium. In chemistry, equilibrium refers to a state where the forward and reverse reactions occur at the same rate, resulting in a constant concentration of molecules in the system.
For example, consider a container divided into two compartments by a permeable barrier. Initially, molecules on one side may be more concentrated, but over time, they will diffuse and spread equally in both compartments, leading to equilibrium.
This concept is significant in many chemical processes, such as the reaction rates, solubility, and phase changes.

Which organelles are replicated during G1 phase, and which during G2?
Some sources state that, depending on the organelle, both phases include organelle replication.
Answer:
G1 involves cell growth an protein synthesis, G2 involvesfurther growth and protein synthesis
Final answer:
In the G1 phase, cells grow and begin the process of organelle replication while in the G2 phase, cells continue to grow, replicate some organelles, and prepare for mitosis by synthesizing proteins and providing resources for the mitotic spindle.
Explanation:
The G1 phase of the eukaryotic cell cycle is characterized by cell growth, where the cell increases in size and organelles begin to replicate in preparation for cell division. This phase involves routine metabolic processes and making proteins needed for DNA replication.
During the G2 phase, the cell continues to grow and makes further preparations for mitosis. It is during this phase that the cell replenishes its energy stores, synthesizes proteins necessary for chromosome manipulation, and duplicates some of its organelles. The cytoskeleton is also dismantled to provide resources for the mitotic spindle. This phase ensures that the cell's machinery is ready for the subsequent mitotic phase where the nucleus and the cytoplasm will be divided during mitosis and cytokinesis.
