FRAME-SHIFT MUTATION:
A frame-shift mutation is a kind of mutation that causes the manner in which a nucleic acid sequence is read in the genetic code. Frame-shift mutation can occur via two major means as follows: deletion and insertion. Deletion mutation occurs when a nucleotide base is removed from the sequence while insertion mutation occurs when a nucleotide base is added to the sequence. Deletion and insertion causes the sequence of nucleotides in DNA to be shifted. Therefore, the type of mutation that is not a type of frame-shift mutation is inversion.Learn more at: https://brainly.com/question/15192321?referrer=searchResults

Cellular respiration converts the reactants' oxygen and glucose into carbon dioxide, water, and energy. The reverse reaction of photosynthesis converts reactants of carbon dioxide and water into oxygen and glucose. These two reactions are part of which biogeochemical cycle?
Answer:
Photosynthesis and Cellular respiration take place in the carbon cycle
Explanation:
One of 4 biogeochemical cycles
carbon cycle
Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration.
Photosynthesis removes carbon dioxide from the atmosphere, while cellular respiration releases it into the environment. Cellular respiration and photosynthesis are significant carbon cycle processes. The carbon cycle refers to the procedures used to recycle carbon in the biosphere.
What cellular respiration in biogeochemical cycle?The exchange of carbon between the biosphere, geosphere, hydrosphere, atmosphere, and pedosphere occurs in one of the biogeochemical cycles. Photosynthesis occurs when carbon dioxide and sunshine are combined in green plants.
Therefore, living beings release carbon into the atmosphere. You emit carbon dioxide (CO2) into the atmosphere with each exhalation. Through a process known as respiration, organisms such as animals and plants must expel carbon dioxide gas.

Which of these conclusions is most likely correct about the two pairs of atoms?
Answer:
D. Carbon and oxygen form covalent bonds but sodium and chlorine form ionic bonds
Explanation:
Chemical bonds form between the atoms of elements. The types of chemical bondings that form are: covalent bond, ionic bond and more. Covalent bonds are bonds formed when atoms share valence electrons rather than transfer it. The shared bonding is in such a way that the outermost shell of both atoms are filled. This is the case of carbon and oxygen atoms in the diagram.
On the other hand, ionic bonding involves the transfer of electrons from one atom to another in order to form electrically charged ions that are bound to one another. This is the case of sodium atom, which has one valence electron in its outermost shell and transfers it to chlorine atom, which has seven electrons in its outermost shell. The sodium atom becomes a positively charged ion (+1) while the chlorine atom becomes negatively charged (-1).

omosexuality is seen only in humans. has been documented for only a few hundred years in only a few societies. likely reflects the input of a number of genes and environmental factors. is inherited from a mutation on the X chromosome. is only the result of environmental influences.
Answer:
Homosexuality likely reflects the input of a number of genes and environmental factors
Explanation:
Sexual orientation can be defined as the attraction that experiments an individual self-identified with a particular gender (either male or female) to other persons according to their sex, this orientation may be classified into three categories: heterosexual (attraction for people of opposite sex), homosexual (same-sex) and bisexual (either sex). In the last years, the mechanisms involved in sexual orientation have been subject to intense research. In this regard, the main part of the scientific community agrees that sexual orientation is the result of the complex interaction between genetic and environmental factors. This hypothesis is supported by the fact that genes whose expression is associated with particular human behaviors, including sexual orientation, have been recently identified and mapped. Moreover, it has been shown that environmental factors such as, for example, hormone exposure before birth (i.e., during fetal programming) may also determine sexual orientation.

Some individuals can be heterozygous for a particular mutation.This means that one of their chromosomes is normal and the other is mutated in some way. Approximately ___ of the gametes produced by an individual heterozygous for a deletion will be non viable.
Answer:
1/2 (50%)
Explanation:
During meiosis, homologous pairs of chromosomes are separated in order to form haploid cells, and this separation or assortment is known to be a random process. In consequence, the chromosome carrying the mutation will have a 1/2 (50%) chance of being inherited in the gamete that, after fertilization, produces a non-viable organism. In consequence, the non-mutated chromosome also will have a 1/2 chance of occurring in the offspring

During meiosis, independent assortment determines which chromosomes a gamete inherits, while ____________ determines, within a chromosome, which material will come from the maternal and paternal version.
Answer:
Crossing over or recombination
Explanation:
Crossing over or genetic recombination is a stage in the late prophase of meiosis I where homologs lie close to each other in pairs to exchange chromosomal material creating new combination of genes as each homologs is derived from either the father or the mother.
This exchange determines the material to be inherited by the offspring producing genetic variation which males the offspring typically different from the parents (genetic variation).
