Answer:
Sharks, rays and skates
Explanation:
Cartilaginous fish include sharks, rays, skates and chimaeras. There are approximately 600 different species of rays and skates and about 500 shark species. Rays and skates live in oceans throughout the world. Most rays and skates live on the bottom of the ocean while some live in open water.
Children inherit half of their genes from parents. Explain Why?
Answer:
This is because the two parents share one or more common ancestors and so carry some of the same genetic material. If both partners carry the same inherited gene change, their children are more likely to have a genetic condition.
Answer:
yes
Explanation:
The chromosomes in cells line up in pairs and exchange bits of genetic material before forming an egg or sperm cell. Each mature egg and sperm then has its own specific combination of genes, which means children will inherit a slightly different set of DNA from each parent.

Mammalian erythrocyte lacks nucleus. Why? Give reason.
Explanation:
Complete answer:
A mature erythrocyte lacks nucleus and mitochondria so as to make a place for the accommodation of more hemoglobin and hence more oxygen molecules. Lack of such organelles also provides the peculiar biconcave appearance of RBCs that aids in efficient diffusion. Young mammalian RBCs are nucleated.

why adaptation is important for living beings
Answer:
Adaption is needed for a living thing to strive in a system, its how they survive.
Explanation:
Adaptation is needed to survive. This includes climate, predators around it etc. For example polar bears. Polar bears adapt to their environment by growing thick coats of fur. These coats keep the bears warm.Without it they would die.

which was TRUE garding the structures of DNA and RNA, and how do they relate to replication and the expression of genes?
A.Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein
B. Replication involves copying a whole molecule to produce a double-stranded molecule of RNA. DNA is a single stranded and if transcribed from a portion of one strand of RNA to produce a protein
C. Replication involves copying a portion of one strand to produce a single-stranded molecule of RNA. DNA is double stranded and is produced by transcribing a whole molecule of RNA to produce a protein
D. Replication involves copying a portion of one strand to produce a single-stranded molecule of DNA. RNA is double stranded and is produced by transcribing a whole molecule of DNA to produce a protein.
Answer:
A.Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein
Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein.
What is Replication?
A double-stranded DNA molecule is copied to create two identical DNA molecules through the process of DNA replication. Because every time a cell splits, the two new daughter cells must have the same genetic material, or DNA, as the parent cell, replication is a crucial process.
The ability of each DNA strand to function as a template for duplication is essential to the replication process. DNA double helix unwinding occurs at specified locations, known as origins, where DNA replication begins.
The production of a primer, a brief section of RNA that serves as the beginning point for the synthesis of fresh DNA, follows. The DNA is then replicated by a protein called DNA polymerase by matching bases to the original strand.
Therefore, Replication involves copying a whole molecule to produce a double-stranded molecule of DNA. RNA is a single stranded and is transcribed from a portion of one strand of DNA to produce a protein.

Enlist the features of cell membrane.
Answer:
It is the outermost covering of a cell that separates the contents of the cell from its external environment.
It only allows the entry and exit of some materials. It also prevents the movement of some. Therefore, it is also called a selectively permeable membrane.
Some substances like carbon dioxide and oxygen can move across the cell membrane due to the process known as diffusion.
Water also obeys the laws of diffusion. The movement of water molecules through a selectively permeable membrane is called osmosis.

Are genetic mutations avoidable? Explain.
Answer:
Mutations happen in our cells all the time. It's actually how all humans grow and change. The vast majority of mutations are harmless. Thus, they aren't avoidable.
Mutations occur in our cells all the time. It's how all humans grow and transform. The vast bulk of mutations is harmless. Therefore, they aren't avoidable.
What are Genetic Mutations?
The permanent transmissible difference in the genetic material. An individual exhibiting such a transformation. A point mutation is a mutation resulting from a modification in a single bottom pair in the DNA molecule.
Any alteration in a nucleotide succession of DNA is called a mutation. Chromosomal, dependent, and gene mutations are some of the illustrations of different kinds of genetic mutations.
