higher energy of products
Explanation:
i did the test and got 5/5
The energy of the reactant is lower and the energy of the product is higher in this kind of reaction, it is called an endothermic reaction.
What is an endothermic reaction?A thermodynamic process in which energy is absorbed is called an endothermic reaction. In this kind of reaction, when heat is given during the reaction, is absorbed by the reactant to form the product. It takes heat from its surrounding.
Some examples of endothermic reactions are:
The melting of ice to form water is an endothermic reaction.When nitrogen and oxygen react with each other to form nitric oxide, it absorbs energy.When ammonium chloride (NH₄Cl) reacts with water (H₂O), it absorbs heat.Hence, the correct sequence is:
The lower energy of reactant → transition state → higher energy of the product.

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.

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.

An individual always has two alleles for the same gene (one on each chromosome). Which statement is true?
a)A person's two alleles are always different
b)A person's two alleles are always the same.
C)A person's two alleles may be the same, and they may be different
Answer:
A
Explanation:
An individual always has two alleles for the same gene (one on each chromosome). The statement which is true is "a person's two alleles may be the same, and they may be different". Thus, the correct option is C.
What are alleles?An allele can be referred to as an alternative form of a gene. An allele is located at a specific position on a specific chromosome. These alleles can be passed on from the parents generation to their offspring through the process of sexual reproduction.
The presence of two identical alleles at a particular gene locus (chromosome) is referred to as a homozygous genotype. This may include two normal alleles or two alleles that have the same variant. The presence of two different alleles at a particular gene locus is referred to as a heterozygous genotype.
Therefore, the correct option is C.

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.

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.
