Which combination of alleles are always involved in the inheritance of a sex-linked trait?
heterozygous alleles
homozygous alleles
alleles that are carried on X and Y chromosomes
alleles that are carried on all chromosomes except the X and Y chromosomes

Answers

Sex-linked genes are transmitted with the sex chromosomes. The combination of alleles that are involved in the inheritance of a sex-linked trait are alleles carried on X and Y chromosomes. Option C)

What is a sex-linked gene?

Genes are physically located and arranged in the chromosomes. Each chromosome contains several genes that vary in length and code for different traits. So, all chromosomes are different, except for the homologous ones.

In mammals, sex is determined by a pair of sex chromosomes, X and Y.

Females are represented by the combination of two X chromosomes, XXMales are represented by the combination of an X chromosome with a Y chromosome, XY.

When talking about sex-linked genes, we refer to genes located in one of the sex chromosomes. In general, genes are linked to the X chromosome.

Being linked to one of the sex chromosomes means that these genes, and their corresponding alleles, will only be inherited together with the chromosome.  

In the case of X-linked genes, a male that inherits the X chromosome from a heterozygous female can express either the dominant or the recessive trait, depending on which allele it got from the mother.

According to this framework, the correct answer is C) alleles that are carried on X and Y chromosomes.

Other things being equal, what is a potential disadvantage of an enzyme having a very high affinity for its substrate?.

Answers

An enzyme with a high affinity for its substrate will require more energy to generate an enzyme-transition state complex (the activation energy of the forward reaction) because the energy of the enzyme-substrate complex will be reduced.

What is the disadvantage of an enzyme having high affinity fir its substrate?

Since the ES complex would be in a "energy trough," the activation energy for the transition state would be quite high.

Tight enzyme-substrate binding will lower the reaction's forward rate constant.A forward reaction's activation energy will increase when an enzyme's affinity for its substrate is high.Because the enzyme-substrate complex will be located in a deep energy well, it will be more stable.

In contrast to the situation where the substrate-enzyme binding is weaker, a tight binding of the substrate to the enzyme will alter the amounts of free substrate and free enzyme. This little modification won't have much of an impact on the reaction kinetics because the substrate concentration is often higher than the enzyme concentration.

It is unlikely that tight binding would result in the active site being altered. Since the enzyme is significantly bigger than the substrate, it is unlikely that it will change shape.

The reaction's forward rate constant will decrease with tight enzyme-substrate binding. It is conceivable that a substrate that is securely bonded would not easily change its shape as it passes from the transition state to the products.

High enzyme substrate affinities will result in a decrease in the energy of the enzyme-substrate complex and an increase in the energy needed to generate the enzyme-transition state complex (the activation energy of the forward reaction).

Answers

Tonicity is the comparison of relative concentrations of two solutions, separated by a selectively permeable membrane.

Tonicity is the capacity of an extracellular solution to cause water to osmotically enter or exit a cell. Tonicity differs from osmolarity in that it considers both the relative solute concentrations and the permeability of the cell membrane to those solutes.When describing whether a solution would induce water to move into or out of a cell, three terms—hypertonic, hypotonic, and isotonic—are used:

A cell will lose volume if it is immersed in a hypertonic solution because there will be a net flow of water out of the cell.

A cell will increase volume if it is immersed in a hypotonic solution because there will be a net flow of water entering the cell.

If a cell is immersed in an isotonic solution, there won't be any net water inflow or outflow, and the volume of the cell will stay constant.

Monarch butterfly caterpillars are completely dependent upon milkweed as a food source between the larval stage and when they pupate (in a chrysalis) and emerge as butterflies. This relationship can be referred to as obligate mutualism.

The concept of mutualism can be understood as a partnership between two different species that is beneficial to both organisms involved. This connection may exist either between members of the same species or between members of two different species. Symbionts is the term given to the species that have this type of connection. All living organisms, including humans, animals, birds, plants, and even microbes such as bacteria, viruses, and fungi, are capable of forming mutually beneficial relationships with one another.

In the case of obligate mutualism, the two species are entirely dependent on one another.

Answers

Action potentials travel swiftly down: axons with myelin and more slowly in axons without myelin.

The conduction velocity of the action potential is faster in myelinated axons,  the nerve impulse generated by an action potential can propagate faster than it loses its strength due to the insulation that protects against signal loss. Similar to the insulation around wires in electrical systems, glial cells form a membrane sheath surrounding axons called myelin, insulating the axon. This myelination, as it is called, can greatly increase the speed of signals transmitted between neurons. The action potential travels down the axon as a result of sodium influx depolarizing near-threshold segments of the axon.

Answers

Cholangiocarcinoma (CC) is a highly lethal malignant tumor that arises from the biliary tract epithelium.

Abstract:

Background:

Cholangiocarcinoma (CC) oncogenesis and development are largely unknown molecular processes. The objective of this study was to map the expression of genes involved in CC oncogenesis and sarcomatous transdifferentiation across the entire genome.

Methods:

DNA microarray technology was used to find the genes that differed in expression between CC cell lines or tissues and cultivated normal biliary epithelial (NBE) cells. Expressions were verified in CC tissues and cells from humans.

Results:

We found a group of 342 genes that are often regulated (>2-fold change) in cell line and tissue samples using unsupervised hierarchical clustering technique. 289 of them, including tumour suppressor genes, were downregulated, while 53 of them, including genes connected to tumours, were elevated (0.5 fold change). Immunohistochemistry was used to confirm the expression of SPP1, EFNB2, E2F2, IRX3, PTTG1, PPAR, KRT17, UCHL1, IGFBP7, and SPARC proteins in human and hamster CC tissues. When sarcomatoid CC cells were compared to three adenocarcinomatous CC cell lines, additional unsupervised hierarchical clustering analysis found 292 differently upregulated genes (>4-fold change) and 267 differentially downregulated genes (0.25 fold change). Immunoblot analysis and immunohistochemistry labelling were used to confirm that 12 proteins were expressed in the CC cell lines. We discovered that during the sarcomatoid transdifferentiation of CC, the methylation-silenced proteins LDHB, BNIP3, UCHL1, and NPTX2 were restored, along with the expression of the proteins linked to the epithelial-mesenchymal transition (EMT), VIM and TWIST1.

In conclusion, identifying molecular targets for cholangiocarcinoma diagnosis and prognosis may be aided by the dysregulation of oncogenes, tumour suppressor genes, and methylation-related genes.

Apes developed some adaptations which help them in this type of locomotion. These adaptations include a lack of tail, a vertical posture, conical rib cage, a mobile lumber vertebrae, wrist rotation, scapulae on their back, grasping limbs with shortened thumbs and long curved fingers.

All these adaptations help the ape to climb and suspend themselves from the branches of the trees and also helps them achieve a swinging motion.
