Explanation: Anaemia is the decrease in the quantity and quality of blood cells in circulation in the body.
There are different types of anaemia,one of them being aplastic anaemia.
Aplastic anaemia is a type of anaemia characterised by reduction in the production of enough new blood cells by the body (bone marrow).
When this occurs,the individual becomes easily tired and prone to infection as a result of weakened immune system.
Aplastic Anaemia can be caused by radiation or chemotherapy,it can also be caused by autoimmune reaction when your body starts attacking it's stem cells in the bone marrow.

Compare the energy values of a carbohydrate molecule versus a fat molecule.
Answer:
A fat molecule is stored with a lot of energy where as a carbohydrate molecule is a long chain of carbon atoms.
Carbohydrates and fats are nutrients which provide energy to the body and since calories(kilocalorie) tell how much energy a molecule of a nutrient contain, We can compare their energy values by first changing to kilocalorie.
Now, 1 gram of Carbohydrates contain 4 kilo calories while 1 gram of fat contains 9 kilo calorie of energy.
Let us consider a piece of bread containing
20g of carbohydrate molecule and
14g of fat molecule.
We will see that
carbohydrate will have 20 x 4 =80kcal and
fat will have 14 x 9=126kcal
Even with the carbohydrate having more mass than Fat, Fat ended up havng more energy value than it.See here for related answer: https://brainly.com/question/2006114

insulin
O antibodies
ligaments
genes
Answer:
antibodies
Explanation:
as antibodies are the part of immune system that fight against diseases and protect our body
while insulin is enzyme which speed the chemical reaction without affecting itself it does not fight against disease
and genes are involve in the inheritance not in the immunity so
correct answer is antibodies which produce immunity
The proteins that help to fight against diseases are ANTIBODIES.
The antibodies are specific proteins of the immune system that recognize harmful particles called antigens in order to destroy them.The antigens can be localized on the surface of pathogenic harmful microorganisms (i.e., bacteria, fungi, parasites, viruses).Antibodies are secreted into the bloodstream by differentiated B cells, which are specific cells of the adaptive immune system known as plasma cells.In conclusion, the proteins that help to fight against diseases are ANTIBODIES.

A scientist is studying the effects of growing human populations on the biodiversity that can be found in a region. Each region selected had a different population density of humans from 1 to 10 million per 10 square miles. Then in each region the number of different species that can be found was recorded. What type of variable is the dependent variable in this experiment?
Answer:
The different species
Explanation:
There are two types of variable in a scientific experiment; Dependent and Independent variable.
An Independent variable is the variable that is intentionally or expectedly altered in order to see the effect on the dependent variable.
A dependent variable is the variable that is been observed for changes as a result of the independent variable.
For example, in the relationship between age and blood pressure, age is the independent variable while blood pressure is the dependent variable.
From the question, the different human populations is the independent variable (because it is the one been intentionally altered) while the biodiversity/different species is the dependent variable (because it is been observed for changes as a result of the different human population).

The muscles of a recently deceased human can remain in a contracted state, termed rigor mortis, for several hours, due to the lack of
Answer:
Because of the remaining actin-myosin bonds.
Explanation:
After death, the body can still continue to produce energy as ATP and that ATP interacts with the myosin within the muscles, causing the muscles to remain contracted and tense. This is what causes rigor mortis, the body is unable to break the bonds between actin and myosin.
I hope this answer helps.
Answer: ATP NEEDED TO BREAK ACTIN-MYOSIN BONDS
Explanation: ATP (Adenosine Triphosphate) is the substance that allows energy to flow into the muscles,this energy helps the muscle to contract and work well so without this chemical (ATP), energy can't flow into the muscles and the muscle in-turn cannot function or contract.
When an individual dies,the body stiffens as a result of loss of Adenosine Triphosphate.
The muscles then stays in a contracted state until ATP becomes binded to myosin, thereafter, myosin and actin filaments will be released from one another.

A mating between a true-breeding purple-flowered pea plant and a true-breeding white-flowered pea plant would produce a:______.A) True-breeding variety.B) Inbred organism.C) F1 generation.D) P generation.E) F2generation.
Answer:
The correct answer would be - option C) F1 generation
Explanation:
The true breeding varieties are the offspring that have same phenotype as the the parents and contain same allele for a specific trait. When there is mating between two true breeding varieties offspring would be hybrid.
P generations is the generation of the parents in other words, matting in between parents known as p generation whereas the very first generation after p generation is known as F1 generation or filial generation and also the hybrid of P generation.
Thus, the correct answer is option C). F1 generation
One strand of the DNA serves as a direct template for the new strand, and the other strand is pieced together and comprises a new strand. This statement best describes _____.
Answer:
DNA replication is the answer
One strand of DNA serves as a direct template for the new strand, and the other strand is pieced together and comprises the new strand. This statement is related to DNA replication.
What is DNA replication?DNA replication is the process by which genetic materials are copied. In this process, the DNA helix unwinds and each DNA strand opens. Enzymes such as DNA polymerase access the single strand and add complementary bases to the already existing DNA or parental DNA.
The DNA replication takes place from the 5' end to the 3' end. The DNA elongation continues from 5' to 3' taking the 3' to 5' parental template DNA strand. This strand is called a "leading strand," as the newly synthesized DNA is formed continuously. The other template DNA strand of parental DNA, with 5' to 3', doesn't elongate continuously in replication. Patches of short DNA are formed. This is called a lagging strand.
Hence, one strand, the leading strand, is formed continuously while the lagging strand is pieced together. This statement best describes DNA replication process.

The zebra mussel is a highly invasive species that was accidentally introduced to the Great Lakes region of the United States in the 1980s. The map below shows the distribution of zebra mussels in 2010. • Zebra mussel location What is the primary reason the large-scale spread of zebra mussels concerns scientists? Zebra mussels out-compete native mussel species. © Zebra mussels are a freshwater species. Zebra mussels are a desired food for humans. Zebra mussels are eaten by some fish and birds.
Answer:
Although the map showing the distribution of mussels in not included but the question can be answered based on general understanding of invasive species. The answer is:
Zebra mussels out-compete native mussel species.
Explanation:
Invasive species in biology refers to the species of an organism that is foreign to a particular area/location with an ability to grow very rapidly to the point of being a threat to the local species of organisms that are native to the area.
This is the case of the Zebra mussel, which was accidentally introduced to the Great Lakes region of the United States in the 1980s. It is a major concern for scientists (like every other invasive species) because of its potential to outgrow and outcompete native mussel species i.e mussel species naturally found in the lake.
