Ans. (D). genes.
Gene represents a sequence of DNA, which codes for a functional molecule (such as RNA or protein). Information about inherited traits is stored and transferred through the genes.
Heredity occurs due to genetic material, which gets passed from parents to their progeny in the form of DNA. During reproduction, all the information for survival, growth, and reproduction, found in the DNA gets transferred to the next generation.
Thus, the correct answer is option (D).

They both have the same species diversity
There is not enough information to determine species diversity
Answer:
The process of digestion in the human body takes place over six (6) steps. This travel log would be documented with each chapter as a step:
Day 1: Ingestion. I do not know how I got into this dark wet room (mouth) with huge white grinders (teeth), but I do not believe I would make it out in one piece; these grinders keep mashing me up n what I believe to be 'chewing'.
Day 2: Propulsion. There's a tunnel (oesophagus). I feel like I'm going down a wet slide.
Day 3: Physical digestion. I think I'm in some sort of sac-like mechanism (stomach)with thick walls that produce some sort of toxic substance (acids and enzymes) to my body. This is where I die.
Day 4 and 5: Chemical digestion and absorption. There is almost nothing left of me; I am being taking in by the walls of this maze (small intestine). More of the 'toxic' substance is coming from what appears to be leaf (liver) and all my constituents are being disintegrated (by the duodenum). Now there's a larger maze (large intestine or colon). I'm being separated and completely absorbed. The things that aren't useful about me (waste/stool) are being sent away.
Day 6: Defecation. Waste is excreted in the nus through the rectum.
I hope this was helpful.

Answer:
O
Explanation:
Type O blood is the universal donor, meaning anyone can receive Type O blood. But there's more to it. Anyone with Rh positive blood can receive O positive blood. O negative blood can be received by all blood types and Rh factors.
The chance that their first child will have type O blood is 25% since the genotypes of offsprings are .
An allele is a particular form of genetic information that can be found in our DNA at a particular spot on a certain chromosome. This form of genetic information is known as an allele. IA, IB, and i are the three distinct alleles that can determine a person's blood type. I is the most common. These three alleles can be referred to as A (for IA), B (for IB), and O for the sake of simplicity (for i).
Therefore, when a man heterozygous for blood type A marries a woman heterozygous for blood type B the chances that their first child will have type O blood is 25% since the genotypes of offsprings are .

b. Mitosis.
c. Meiosis.
d. Transcription.
Alleles undergo segregation ispresent in the mitosis. The answer is B. The first stage is prophase. Thenucleolus disappears and the two centrosomes begin to form the mitotic spindle.The spindle xtends between two opposite poles f the cell. Next is the metaphase.The centromeres of the chromatid pairs align at the center of the mioticspindle. Then anaphase, the centromeres will split that separates the chromatidpair. In here, alleles are formed. They are now called chromosomes. The lastphase is the telophase. The chromosomes will then form a thread-like chromatinand for ache envelope, a nucleoli appears.
Answer:
The spleen acts as a filter for blood as part of the immune system. It also helps fight against certain kinds of bacteria that cause pneumonia and meningitis.
