Explanation:
To reproduce, female elephants produce eggs and male elephants produce sperm. Offspring are produced by the fusion of an egg with a sperm cell. Which statement is true about the offspring?
A. The offspring are genetically identical to the parents because they are produced by sexual reproduction.
B. The offspring are genetically distinct from the parents because they are produced by sexual reproduction.
C. The offspring are genetically distinct from the parents because the egg and sperm are both diploid.
D. The offspring are genetically identical to the parents because the egg and sperm are both diploid.
Answer:
The right answer is B. The offspring are genetically distinct ... by sexual reproduction.
Explanation:
Sexual reproduction, as opposed to asexual reproduction, indicates that the propagation of a species involves male and female gametes. It is the main method of reproduction of multicellular organisms.
In the first stage of sexual reproduction, meiosis, the number of chromosomes is reduced from a diploid number (2n) to a haploid number (n). During fertilization ("fertilization"), haploid gametes come together to form a diploid zygote and restore the initial number of chromosomes (2n).
13. Why are insertion and deletion mutations so much more damaging to the final polypeptide structure than substitution mutations?
Please help!!
Answer: Insertion or deletion results in a frame-shift that changes the reading of subsequent codons and, therefore, alters the entire amino acid sequence that follows the mutation, insertions and deletions are usually more harmful than a substitution in which only a single amino acid is altered.
Explanation:
Two parents are planning to have children. The father is heterozygous for type B blood. The mother is heterozygous fir type A blood what are all the different genotypes that there chirldren may inherit
Answer: Possible genotypes: AB, AO, BO, or OO
Explanation: The mother is heterozygous for type A blood so her genotype must be AO. The father is heterozygous for type B blood so his genotype must be BO. After crossing the two in a punnet square, you’ll get the listed genotypes. The phenotypes for this same problem would be blood type AB, type A, type B or type O, because types A and B are dominant to type O.

Explanation:
Although DNA is present in all organisms, the genetic code contained in the DNA creates
differences between all species. The DNA of an amphibian, such as a frog, is different from
the DNA in a human because a frog's DNA
A. contains a different number and sequence of nitrogenous bases
B. contains larger, more inclusive phosphate groups
C. lacks guanine and adenosine
D. does not contain as many hydrogen bonds between base pairs.
Answer:
The DNA of an amphibian, such as a frog, is different from the DNA in a human because a frog's DNA contains a different number and sequence of nitrogenous bases (option A).
Explanation:
DNA is the molecule that contains all the genetic information of the different species of living beings, being a molecule that is present in all of them.
Although the DNA of all living beings has the same basic structure —four nitrogenous bases, a deoxyribose and a phosphate group— what makes the differences between species is the length of the DNA molecule and the different sequences of nitrogenous bases present in the molecule. It is for this reason that frog DNA is different from human DNA.
The other options are not correct because:
B. There are no differences in the phosphate groups from one species to another.
C. All DNA molecules contain guanine and adenine.
D. Hydrogen bonds between nitrogenous bases depend on the amount of paired bases, but are not related to differences in DNA between species.
Explain whether the female is pregnant.
Answer:
According to the hormone diagram of the menstrual cycle, the woman is not pregnant due to the behavior of progesterone and estrogens, whose levels do not increase, in addition to the absence of human chorionic gonadotropin.
Explanation:
The graph shows the behavior of hormones during a woman's menstrual cycle in the absence of pregnancy.
During a woman's normal cycle, estrogen, luteinizing hormone (LH) and follicle stimulating hormone (FSH) tend to increase prior to ovulation, reach their peak values at ovulation, and then decline, as shown in the graph. Progesterone, on the other hand, increases after ovulation and decreases if the woman does not become pregnant.
In the case of a pregnant woman:
Estrogens continue to increase after ovulation, produced by the ovaries and placenta.Progesterone also increases its levels, as it is a hormone produced by the ovaries and placenta.Hormone human chorionic gonadotropin (HCG) appears and increases during pregnancy, due to the secretory activity of the placenta.The diagram represents the normal cycle of a woman who is not pregnant.

Answer:
According to the diagram shown, the section of DNA used to make the mRNA strand is known as a gene (option 2).
Explanation:
Gene consists of a DNA fragment that codes for the synthesis of a specific protein that defines the structural or functional trait of a living being.
When DNA is transcribed into mRNA, each section of transcribed DNA is part of a gene. The information travels to ribosomes in the cytoplasm where protein synthesis occurs.
A complete DNA molecule forms a chromosome, which contains the genes with information to define specific traits of a species.
The other options are not correct because:
1.Carbohydrate is a biomolecule that is not involved in the genetic process.
3. Ribosome is where protein synthesis occurs.
4. Chromosome is the complete DNA molecule.
The section of DNA being used to make the strand of mRNA is known as - 2. gene
Geneis the basic physical and functional unit of heredity.Genes are made up of DNA, a particular base sequence of DNA is termed as a gene for a specific protein.Each gene is a unique base sequence.Some genes act as instructions to make molecules called proteins. However, many genes do not code for proteins.In humans, genes vary in size from a few hundred DNA bases to more than 2 million basesThese sequences are encoded in the form of mRNA during transcription and then move to the translation process and make proteins.Thus, The section of DNA being used to make the strand of mRNA is known as - 2. gene

Answer:
Global warming results in increased rainfall in the North Atlantic, and the melting of glaciers and sea ice, the influx of warm freshwater onto the sea surface could block the formation of sea ice, disrupting the sinking of cold, salty water.
Explanation:
Ocean currents and broader circulations move vast amounts of water around the world, redistributing heat and energy, and helping regulate the global climate. This conveyor brings warm water northward in the western North Atlantic and actually contributes slightly to the Gulf Stream.

Answer:
According to Punnett Square, what can be concluded from Huntington's disease is that the disease is autosomal dominant.
Explanation:
Huntington's disease is characterized as a neurodegenerative condition, which affects body movements and progressively decreases some higher brain functions.
Inheritance plays a determining role in Huntinton's disease, being a disease transmitted from parents to children with an autosomal dominant pattern, that is, all individuals with the defective gene (H) will have the disease, while the absence of the gene (rr) also guarantees the absence of this condition.
The other options are not correct because:
Inheritance of Huntington's disease is not sex-linked. The allele that determines the Hungtinton's disease is not recessive.pls pls help!! :( it’s due in an hour
