Joint and bone pain, fever, weight loss, fatigue, weakness, hepatomegaly, splenomegaly and enlarged lymph glands are typical symptoms of leukemia. True False
Answer:
True.
Explanation:
White blood cells cannot function properly and their reduced production can lead to fever and frequent infections. This is because the function of white blood cells in fighting germs has been disrupted.
Other signs and symptoms:
- Weak and tired.
- Lack of appetite and weight loss.
- Swelling and bleeding gums.
- Headache.
- Abdominal swelling is caused by enlargement of the liver and lymph.
- Bone pain, can cause weakness.
Joint pain.
- The glands are swollen. If the glands in the neck and chest are swollen, it can cause blood flow to be blocked. This causes the face to swell, difficulty breathing and snoring.

Answer:
mechanically-gated
Explanation:
what three conditions are necessary for natural selection to occur
For the natural selection to occur, the basic rule is that species that fit the best are selected by nature to exist in the nature. The 3 conditions that are required by nature for natural selection to occur are :
1. Struggle for existence
2. Variation
3. Inheritance
What is natural selection ?The offspring that is fit for the nature following the adaptation to the variation and inheritance crossing the struggle for existence to occur in nature tends to be selected by the nature to exist and produce more offspring.
The organisms that are adapted to the nature following the mutations and variations that are required for the better adaptations live more than the species which has lesser adaptation. These species produce more offspring.

the tree of life has been rearranged into three domains based on what evidence?
The tree of life has been rearranged into three domains based on DNA similarities. The linear order of nucleotides in DNA can be used to infer ancestry.
The three domains of the tree of life are Bacteria, Archaea and Eukarya.
Moreover, DNA is a double helix molecule composed of two long chains of nucleotides.
In DNA, there are four types of nucleotides, each containing one different nitrogenous base: Adenine, Guanine, Cytosine and Thymine.
The level of conservation observed in the linear order of nucleotides in the DNA molecule can be used to recognize homology caused by ancestry (i.e., homology in the nucleotide sequence) between different types of organisms.

Suppose a father of blood type A and a mother of blood type B have a child of type O. Is this possible? If they have more children, what could their blood types be?
Answer:
no it can't be possible (but it depends if the fathers blood group is AA not AO and the mother's group is BB not BO) otherwise it can't be possible
Explanation:
blood group O is recessive so both parents must have this type of blood group or at least one of them to have an offspring with this blood group
if they had more children they'd have blood groups A,B or AB
So now this is an easy question.

Option A and B are true because mitochondria have their own DNA known as mitochondrial DNA. Also, they make some of their own proteins because they have their own DNA and ribosomes. So they are also called semi-autonomous organelles.
They are not static because their structure changes every few seconds.

why is gmo modification different for plants and animals
In animals, a gene is inserted into an embryo, modifying the genome to manufacture the product of this new gene. In plants, a gene is injected into a single cell that is grown from a seed into a plant. This plant expresses the new gene in all its cells. The difference between GM and selective breeding.
If you know that a DNA double helix consists of 20 % adenine, what percentage of the DNA double helix is guanine (G)
Answer:
80%
Explanation:
As per rules the percentage of adenine is equal to thymine and C is equal to G. If A is 20 then the value of T is 20 too and along with that C and G are equal. The value of G is 30%.
What type of bonding is present between adenine and thymine ?Hydrogen bonding is present between the bases where the two hydrogen bonds are present in between A and T. C and G are binding together by three hydrogen bonds.
Adenine is 20% that means thymine is equal to 20% as well where the remaining percentage out from 100 % is 60% where the value if cytosine and guanine are equal and the percentage they have is 30% and 30% that is guanine is 30%.
DNA always in the structure has adenine residues equal to thymine residues and cytosine residues equal to guanine residues thus the value of their composition in the structure can be predicted by this.

Areas of the body with a high degree of sensory acuity (very sensitive) have _________ receptor fields.
Areas of the body with a high degree of sensory acuity (very sensitive) have SMALL receptor fields. It determines how accurately a stimulus can be located.
Sensory acuity indicates how accurately a given stimulus is located.
Sensory acuity depends on two major factors: the density of sensory receptors, and the size of receptive (neuronal) fields.
These receptors can respond to different stimuli such as, among others, temperature factors (i.e., thermoreceptor), chemical factors (i.e., chemoreceptor), pressure factors (i.e., mechanoreceptor), etc.
