During which process is energy released 1. external respiration 2. internal respiration

yarga [219]

Answer:

Internal

Explanation:

During cellular respiration, glucose is broken down in the presence of oxygen to produce carbon dioxide and water. Energy released during the reaction is captured by the energy-carrying molecule ATP.

Colorblindness is caused by a recessive x-linked gene. a woman that is heterozygous for this trait marries a man with normal col

IrinaK [193]

Answer;

The offsprings will be such that , a normal vision female, a heterozygous female, normal male and a colorblind male.

Explanation;

-Most X-linked traits in humans are recessive. One example of an X-linked trait is red-green colorblindness. Let (Xc) represent the recessive allele that causes colorblindness and (XC) represent the normal dominant allele. Females that are XCXC or XCXc have normal color vision, while XcXc females are colorblind. For males with; XcY are color blind, while those with XCY are have normal color vision.

Heterozygous female, XcXC

Normal male, XCY

The offspring of the parents, XcXC x XCY, are: XcXC (heterozygous female), XCXC( normal vision female), XCY (normal vision male), XcY (color blind male).

vagabundo [1.1K]

ATP is not generated directly in the citric acid cycle. Instead, an intermediate is first generated by substrate-level phosphorylation. The intermediate is GTP.

A purine nucleoside triphosphate is guanosine-5'-triphosphate.
It serves as one of the components necessary for the creation of RNA during transcription.
The main distinction between its structure and that of the guanosine nucleoside is the presence of phosphates on the ribose sugar of nucleotides like GTP.
Also known as guanosine triphosphate, this energy-dense nucleotide is similar to ATP and is made up of guanine, ribose, and three phosphate groups.
It is required for the creation of peptide bonds during protein synthesis.
Adenine nitrogenous base, sugar ribose, and triphosphate make up ATP, a nucleoside triphosphate, whereas guanine nitrogenous base, sugar ribose, and triphosphate make up GTP.
This is the main distinction between the two compounds.
The alpha-guanosine subunit's diphosphate (GDP) is converted into guanosine triphosphate (GTP), and the GTP-bound alpha-subunit subsequently separates from the beta- and gamma-subunits.

Meiosis Foldable Activity 515.2

Aleksandr-060686 [28]

Explanation:

During the process of prophase I, the nuclear envelope containing chromosomes has only partly broken down homologous chromosomes are joined together by proteins and a complex or pairing call synapsis- corresponding genes on sister chromatids are aligned precisely.

The syanapsis allows for crossing over which is the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined.

Further Explanation:

All the genetic information within the eukaryotic cell is stored within the nucleus as helical DNA. This DNA is tightly wound around histones as chromosomes. In meiosis, the number of chromosomes (2n) is halved to 23 chromosomes (haploid number)through meiotic divisions, producing 4 haploid (n) germ cells or gametes (sperm or eggs), each containing half the number of chromosomes as its parent cell.

In Meiosis I

homologs pair off into bivalents
At crossing over: the exchange of segments of chromosome, between non-sister homologous or similar chromatids crossing over happens at chiasmata, the point where non-sister chromosomes are joined in prophase I forming bivalents; tetrads are formed.
Spindle fibers from centrioles join sister chromatids together at their centromeres in metaphase I, pulling them to the equator of the cell;
then, in anaphase I, while joined, they are pulled to opposite sides of the cell; the cell body splits and the nuclear envelope reforms in telophase I

In Meiosis II...

Later, in prophase II, the nuclear envelope disintegrates and mitotic spindle fibers are formed
independent assortment occurs. in metaphase II of meiosis: spindle fibers attach to centromeres, chromatids align independently at the equator. Genes segregate independently into new combinations as sister chromatids are pulled apart by their centromeres in anaphase II
in telophase II the cells' nuclei and membrane are then formed with each containing the haploid number (n)
Following the formation of gametes in the last stage, randomized fertilization occurs in sexual reproduction sperm cells fertilize an ovum to form a zygote. This occurs randomly by chance, to result in a complete set of chromosomes 2n, that is a novel combination of half each parent's number of chromosomes
