Special chemicals that recognize and attach to germs are called what?
A. Antibodies
B. Red blood cells
C. Pathogens
Answers
Special chemicals that recognize and attach to germs are called Antibodies. Thus, the correct option is A.
What is Antibody?An antibody may be characterized as a protein produced by plasma cells in response to a specific antigen.
The major function of an antibody is to eliminate disease-causing organisms which are known as pathogens or any other external germs and barricade them from contaminating human cells.
Such antibodies after synthesis attach to germs or digested antigenic particles and then mediated the process of eliminating all such foreign particles.
Therefore, special chemicals that recognize and attach to germs are called Antibodies. Thus, the correct option is A.

Which statement correctly describes gravity?
A. a repulsive force that acts between all objects through contact
B. a repulsive force that acts between all objects without contact
C. an attractive force that acts between all objects without contact
D. an attractive force that acts between all objects through contact
Answers
Answer:
C. an attractive force that acts between all objects without contact
Explanation:
The force of gravity, first discovered by Isaac Newton, is one of the four fundamental forces. It is a force that is always attractive, and it is exerted between all objects that have mass. Also, the force is exerted even when the two objects are not in contact.
The magnitude of the force of gravity between two objects is given by
where
G is the gravitational constant
m1 and m2 are the masses of the two objects
r is the distance between the two objects

Although the liver and the pancreas are not part of the digestive tract, they are important to the process of digestion because: a. Secretions they produce help to digest food b. They absorb nutrients into the bloodstream c. They eliminate wastes from the body d. All of the above
Answers
Answer:
The correct answer is - d. all of the above.
Explanation:
The liver and pancreas are not part of the digestive tract but they play a very major role in the process of digestion. The liver and pancreas both produce and secretes the enzymes and bile to breakdown the food into nutrients. Bile digests the fat while enzymes of the pancreas break down protein, carbohydrates, and fats.
The liver helps in absorbing the fats and some vitamins and minerals to the bloodstream from the nutrient from digested food. They also help in the removal of toxins and wastes from the digested food or the waste products of breaking down into nutrients through the feces or filtered from the blood by the kidneys.
All cells divide and reproduce the same way ... true or false explanation needed
Answers
Answer:
False
Explanation:
False because cells can reproduce in two ways. Mitosis, the process of making new body cells or cell division. OR Meiosis where there is genetic information transfered between cells such as how humans are made.
All cells do not divide and reproduce the same way since there are two methods for cells to divide. So, the given statement is False.
What is Cell division?The process by which a parent cell divides into two daughter cells is known as cell division. Cell growth and chromosome replication precede cell division, which often happens as part of a longer cell cycle. Usually, cell division happens as part of a longer cell cycle where the DNA is reproduced as the cell nucleus divides during cell division.
Meiosis and mitosis are the two processes through which cells can reproduce. The process of creating new body cells, or mitosis, differs from meiosis, which is the process by which genetic material is passed between cells, as in the creation of humans. Thus, not all cells divide and reproduce in the same way.
Therefore, the given statement is False.

Answer:
Multiple

The presence of many alleles for the trait to be expressed is called "multiple allelism," the presence of two alleles for the trait to be expressed is called "recessive," and the presence of a single allele for the trait to be expressed is called "dominant."
What are the dominance and multiple allelic patterns?There are different types of genes in animals and plants, such as some that have two copies of alleles, but if one is present, it can express itself in a heterozygous state, which is called a dominant gene because it can suppress the other allele, but some genes can only express themselves when there are many alleles, which are called multiple alleles.
Hence, the presence of many alleles for the trait to be expressed is called "multiple allelism," the presence of two alleles for the trait to be expressed is called "recessive," and the presence of a single allele for the trait to be expressed is called "dominant."

In Labrador dogsblack fur (B) is dominant over golden fur (b). If you cross two heterozygous parents, what percent of offsprings will have golden fur?
Answers
Answer:
25%
Explanation:
This question involves a single gene coding for fur color in Labrador dogs. The allele for black fur (B) is dominant over the allele for golden fur (b). This means that a heterozygous dog (Bb) will have a black fur.
According to this question, if two heterozygous parents are crossed i.e. Bb × Bb, the following gametes will be produced by each parent: B and b. Using these gametes in a punnet square (see attached image), the following proportion of offsprings will be produced:
Black fur (BB, Bb) = 3/4
Golden fur (bb) = 1/4
Hence, the percentage of offsprings that will have golden fur is 1/4 × 100 = 25%.
4. Use the table below to choose the incorrect statement.
A.Goldfish sperm cells have 47 chromosomes.
