Explanation:
If a person develops chronic lymphocytic leukemia, what leukocytes may be involved and how mature are they in the bloodstream? Common symptoms of all types of leukemia are caused not only by the poor functioning of leukocytes, but also by the loss of erythrocytes and platelets. These formed elements have a reduction in their number because the tissue that normally produces them is crowded out by the uncontrolled growth of the leukocyte-producing tissue. For each symptom below, state whether leukocytes, erythrocytes, or platelets are involved.
anemia
easy bleeding
repeated infections
enlarged lymph nodes
shortness of breath
excessive bruising
Answer:
The correct answer is -
anemia- erythrocytes
easy bleeding- platelets
Repeated infections - leucocytes
enlarged lymph nodes- leucocytes
shortness of breath- erythrocytes
excessive bruising- Platelets
Explanation:
Cancer of the lymphocytes is chronic lymphocytic leukemia (CLL). Lymphocytes are a type of white blood cell involved in the body's immune system.
Platelets are tiny blood cell fragments that help your body form clots to stop bleeding. The platelets then rush to the site of damage and form a plug, or clot, to repair the damage.
Erythrocytes are red blood cells that travel in the blood. They carry oxygen from the lungs to the body and bring carbon dioxide back to the lungs to be expelled.
Leucocytes- White blood cells (also called leukocytes or leucocytes and abbreviated as WBCs) are the cells of the immune system that are involved in protecting the body against both infectious disease and foreign invaders.
How does non-random mating cause
evolution?
A. A population that ensures each individual reproduces
causes the population to evolve.
B. When multiple species mate with each other the
population evolves.
C. Individuals choose their mates, meaning that some
individuals pass on their genes and other do not.
D. Individuals that mate with the same individual every
year help evolve their population.
What is the effect of these currents on Earth's temperatures?
Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics. Thus, ocean currents regulate global climate, helping to counteract the uneven distribution of solar radiation reaching Earth's surface.
The liver develops: as a ventral outgrowth of the embryonic foregut. incorporates both endodermal and mesodermal components. develops in the ventral mesentery. is connected to the stomach by the lesser omentum. All of the above.
Answer: All of the above.
Explanation:
The liver is simply the largest solid organ in the body and it can be found below the rib cage in the upper abdomen by the right. It's function is to maintain the blood sugar, regulate blood clotting and remove toxins from the blood.
It should be noted that the liver develops as a ventral outgrowth of the embryonic foregut. It also helps in the incorporation of both the endodermal and the mesodermal components. Furthermore, it's developed in the ventral mesentery and is connected to the stomach by the lesser omentum.
Therefore, all of the above options are correct.
why is meiosis called reduction division?
: Meiosis is sometimes called "reduction division" because it reduces the number of chromosomes to half the normal number so that, when fusion of sperm and egg occurs, baby will have the correct number. Therefore the purpose of meiosis is to produce gametes, the sperm and eggs, with half of the genetic complement of the parent cells.
An element has an atomic mass number of 16 and an atomic number of 7. The element has protons and neutrons. Reset Next

Give reason. Mosquitoes and housefly are placed in the phylum arthropoda
Mosquitoes and Housefly are grouped under the phylum Arthropoda because they both posses jointed legs (or appendages).
Animals that have jointed appendages are called Arthropods (i.e animals with jointed legs). They are triploblastic (i.e they have 3 germ layers) and exhibit bilateral symmetry. They are both six-legged arthropods sub-grouped under the class Hexapoda (coined from the word "hexa" meaning six and "Poda" meaning leg). Their body are divided into three parts; head, thorax and abdomen.

If a small drop of tiny particles such as pollen grains are dropped into a drop of water on a microscope slide, they will appear to vibrate and spread out. The primary reason for this is a. Currents in the water are pushing them around. b. They have internal energy and that is causing them to move. c. They are being continually struck by randomly moving water molecules from all sides and those strikes fluctuate and are sometimes uneven. d. Internal forces between the particles cause them to repel and attract.
Answer:
Internal forces between the particles cause them to repel and attract.

characteristics between invertebrates and vertebrates in a tabular form.
Answer:
Invertebrates: Do not possess a backbone and doesn't have an internal skeleton. Has an exoskeleton. Are generally smaller than vertebrates. Possess an open circulatory system. The majority have compound eyes. Includes radial or bilateral body symmetry. Presence of a simple and unorganized nervous system. Mode of nutrition includes Autotrophic, Parasitic, and Heterotrophic. 95% of animal species are invertebrates. Flatworms, arthropods, sponges, insects are few examples of Invertebrates.
Vertebrates: Possess a backbone and has an internal skeleton. Does not have an endoskeleton. Larger than invertebrates. Possess a closed circulatory system. Do not have compound eyes. Has bilateral body symmetry. Presence of complex and highly specialized organ systems with specific functions. The mode of nutrition is usually heterotrophic. 5% of animal species are vertebrates. Mammals, fish, reptiles, amphibians, and birds are examples of Vertebrates.
what is a structure on a hawk that allows it to survive in its environment and how
Answer:
Hawks have many adaptations that enable them to survive in high places.
Explanation:
They have hollow bones that gives them buoyancy for flight.
They have good eyesight for hunting prey.
They have feathers to keep them warm during cold weathers. The feathers also add to their ability of flight.
They have claws or talons for attacking prey. They have sharp beaks for tearing into the flesh of their prey.

essential for getting good results. Did you find that certain steps in the
procedure had to be followed carefully to get consistent results? If you wanted
better results, do you think there is a step that could have been added to the
procedure?
2. Discuss your thoughts on the overall lab design. Did it help you understand the
concepts better, or did it raise more questions? Do you think you could have
designed a better experiment? If so, explain how and then discuss it with your
classmates. Share some of your knowledge with them to learn a little more
about this experiment.
Anaerobic respiration of yeast produces ethanol and carbon dioxide, which can be experimentally tested by determining the rate of CO2 production in a closed system.
What is anaerobic respiration?Anaerobic respiration is a series of chemical reactions by which certain organisms can produce energy (ATP) in absence of oxygen.
Anaerobic respiration is useful in experimental settings to determine the survival rate of yeast, which can be determined by measuring the concentration of products of this process.
The experimental procedure requires the use of a closed system to determine the rate of change between reactants (glucose) and products (ethanol + carbon dioxide).
In conclusion, Anaerobic respiration can be experimentally tested by determining the rate of CO2 production.
