Answer: d.) The termite has a symbiotic relationship with cellulose-digesting microorganisms in its digestive tract.
Explanation:
Termites are the wood eating parasites. They eat wood to meet their nutritional demands. Although there are enzymes present inside the termites which can partially digest the cellulose. But they exhibit a symbiotic relationship with the bacteria present in their gut. The bacteria helps in digestion of rest of the cellulose. In return the bacteria receives shelter and food.

A steady supply of _________ is needed throughout the body in order for electrons to be accepted at the end of the electron transport chain.
Answer: Oxygen
The cells use oxygen molecules during oxidative phosphorylation. Oxidative phosphorylation is the final stage of cellular respiration which is made up of two closely connected components: 1) the electron transport chain and 2)chemiosmosis.
Oxygen sits at the end of this electron transport chain, where it accepts electrons and picks up protons to form water. If oxygen is not available to accept electrons, the electron transport chain will cease running, and ATP Adenosine triphosphate) will no longer be produced by chemiosmosis. Without enough ATP, cells can’t carry out the reactions they need to function, causing death.
why will a radioactive rock never become completely stable?

Which procedure is performed to affix sagging breasts in a more elevated position??
Final answer:
A breast lift, also known as mastopexy, is performed to affix sagging breasts in a more elevated position. It involves removing excess skin and reshaping the breast tissue to achieve a more youthful and uplifted appearance.
Explanation:
The procedure performed to affix sagging breasts in a more elevated position is called a breast lift, also known as mastopexy. This is a surgical procedure that involves removing excess skin and reshaping the breast tissue to achieve a more youthful and uplifted appearance.
During a breast lift, the surgeon will make incisions usually around the areola and may extend vertically and horizontally depending on the amount of sagging. The breast tissue is then lifted and reshaped, and any excess skin is removed. The nipples and areolas are repositioned to a higher position on the breast.
It's important to note that a breast lift does not significantly change the size of the breasts or provide a fuller appearance. If a patient desires both a lift and an increase in breast size, a breast augmentation with implants may be recommended.

Which structure of a paramecium holds a "reserve copy" of all the cell's genes?
In a Paramecium, the micronucleus holds a 'reserve copy' of all the cell's genes and is essential for sexual reproduction, as well as the formation of a new macronucleus.
In a Paramecium, the structure that holds a "reserve copy" of all the cell's genes is the micronucleus. While the macronucleus manages most of the biological functions such as asexual binary fission, the micronucleus is critical for sexual reproduction and serves as a genetic reservoir. During the sexual reproduction process known as conjugation, the micronucleus undergoes meiosis and subsequent exchange of genetic material with another Paramecium, ensuring genetic diversity. Following conjugation, the micronucleus gives rise to a new macronucleus, thus supporting cellular rejuvenation and ensuring a continuity of the genetic blueprint.

What has led scientists to believe that echinoderms are more closely related to humans and other vertebrates than to cnidarians?
Final answer:
Echinoderms are more closely related to humans and other vertebrates than to cnidarians because both are deuterostomes, a group determined by specific embryonic development patterns and characterized by having a sophisticated endoskeleton.
Explanation:
Scientists believe that echinoderms are more closely related to humans and other vertebrates than to cnidarians because both echinoderms and chordates (the phylum that includes humans) are classified as deuterostomes. This is a significant classification that is determined by the pattern of embryonic development, where in deuterostomes, the anus develops from the first opening in the embryo (the blastopore), and the mouth forms secondarily. In contrast, protostomes develop the mouth from the blastopore. The shared deuterostome development pattern is just one of the reasons echinoderms and vertebrates are considered more closely related. Additionally, echinoderms possess an endoskeleton made up of calcareous ossicles covered by the epidermis, which is conceptually similar to the vertebral endoskeleton of humans and other vertebrates, further supporting the close phylogenetic relationship between the two groups.

According to the hardy-weinberg principle, if 75% of the alleles in the gene pool are a1 and 25% are a2, what is the proportion of individuals with genotype a1a2 in this population?
According to the Hardy-Weinberg principle, the proportion of individuals with genotype a1a2 in a population can be calculated using the formula 2pq, where p is the frequency of allele a1 and q is the frequency of allele a2.
Explanation:According to the Hardy-Weinberg principle, the proportion of individuals with genotype a1a2 can be calculated using the formula 2pq, where p is the frequency of allele a1 and q is the frequency of allele a2. In this case, the frequency of a1 is 0.75 and the frequency of a2 is 0.25. Therefore, the proportion of individuals with genotype a1a2 is 2(0.75)(0.25) = 0.375, or 37.5%.

What is likely phenotypic ratio resulting from a dihybrid cross with alleles showing epistatic interactions?
The answer is one (1) phenotype. This is because epistasis interaction of gene alleles involves the masking of one phenotype of an allele of a gene (at one or more loci) by the other. Alternatively, the epistatic alleles may interact to cause a modification of a phenotype.
Final answer:
The phenotypic ratio from a dihybrid cross which includes epistatic interactions differs from the non-epistatic 9:3:3:1 ratio, with the actual ratio depending on the specific nature of the epistatic relationship between the genes involved. One gene may mask the effects of another, altering the expected ratios of phenotypes in the offspring.
Explanation:
The phenotypic ratio resulting from a dihybrid cross with alleles that show epistatic interactions will differ from the classic 9:3:3:1 ratio seen in Mendel's dihybrid crosses with non-interacting genes. This is because epistasis is a form of gene interaction where one gene masks or modifies the expression of another. For example, if one gene's expression is completely dependent on another gene, you might see a modified ratio such as 9:3:4, where the 4 represents the epistatic effect.
In a case of epistasis similar to the one described by the figure, where one gene (C) masks the expression of another (A) for a trait like coat color, the presence of the C allele is necessary for color to be expressed. If it's absent (cc), no color is expressed regardless of the A gene's alleles. Here, the phenotypic ratio can deviate significantly from the typical 9:3:3:1 observed in a dihybrid cross without epistasis. The actual ratio will depend on the specific epistatic relationship between the genes involved.
It's important to remember that the independent assortment of genes and Mendelian inheritance can be altered by various genetic interactions, including epistasis, which must be taken into account when predicting phenotypic ratios in genetics problems.
