The person might be suffering from pectus excavatum or funnel chest.
Pectus excavatum
The funnel chest is caused by the depression formed towards the lower portion of the sternum. The deformation of the sternum can be symmetrical or one side might be more prominent than the other. Such a condition can affect the normal functioning of the heart and lungs and might induce a feeling of insecurity in the children because of their body shape. Funnel chest is more common in young males than in females and its symptoms include
BreathlessnessChest painFatigueDizzinessTachycardiaIt can be present during birth or may develop as the child grows. An X-ray or a CT scan is used to diagnose the patient. Cardiopulmonary exercise testing (CPET), heart scans, breathing tests, etc are used to gauge the severity of the condition. Most often people with such conditions are able to live a normal life.

When compared to the positive control, a disinfectant dilution is considered to be useful if it stops bacterial growth.
Choosing a disinfectant:
When selecting a disinfectant, keep the following things in mind:
The range of bacteria that need to be eliminated. Look into the specifications of the manufacturers.The conditions of usage of disinfectant.Application of disinfectants :
Activity: it is necessary for efficient disinfection since, once diluted, it degrades over time. Different disinfectants deteriorate at different rates. Obtain data from the manufacturers. Disinfectants that don't have a color indication, like Virkon, should be marked with an expiration date.Touch time: it has to be verified that the manufacturer's data to make sure the organism stays in contact for the specified amount of time. Considering that solid materials like cells and tissue granules are difficult for disinfectants to penetrate, autoclaving would be a more effective way to inactivate.Therefore the correct choice is an option (A).

____________________ theory is the theory that proposes that chloroplasts and mitochondria evolved from certain types of bacteria that eukaryotic cells engulfed.
The endosymbiotic theory proposed that the mitochondria and the chloroplast evolve from some types of bacteria which the eukaryotic cells engulfed.
The endosymbiotic theory tries to explain how the eukaryotic cells came into existence from prokaryotic cells. According to this theory, the eukaryotic organelles like the mitochondria and the chloroplasts were actually free living prokaryotes and were taken in one after the other via endosymbiosis.
This theory has been backed by evidences which establish the phylogenetic similarity between mitochondria and bacteria and also between chloroplast and cyanobacteria. The evidences include the presence of circular DNA in both chloroplast as well as the mitochondria and also the fact they divide by binary fission like bacteria.

b. less than 10,000 years
c. 100,000 to 1 million years
d. 1–10 billion years
a. 10–100 million years is the answer.
Solar mass stars are thought to accrete rapidly. Premain sequence solar mass protostars are probably formed by the collapse of part of a molecular cloud into the "cloud core" in about 105 years (Hartmann, 2000). Strong outflows and jets are sometimes observed.
Star formation begins with the collapse of molecular clouds and fragmentation into highly dense masses. These masses initially contain about 0.01 solar masses, but increase in mass as the surrounding matter is collected by accretion.
Protostars are very young stars, still collecting mass from their original molecular clouds. The protostar stage is the earliest in the process of stellar evolution.

If a mutation occurs when forming a _____, the mutation could be passed on to the next generation.
If a mutation occurs when forming a germ cell the mutation could be passed on to the next generation. If a gene is altered in a germ cell, the mutation is termed a germinal mutation. Because germ cells give rise to gametes, some gametes will carry the mutation and it will be passed on to the next generation when the individual successfully mates.
A mutation passed to the next generation when acquired mutation occurs in an egg or sperm cell. Once an acquired mutation is passed down, it is a hereditary mutation. Acquired mutations are not passed down if they occur in the somatic cells, meaning body cells other than sperm cells and egg cells.

If the heterozygous phenotype is intermediate between that of the homozygotes this is called independent dominance. The correct answer is B. incomplete dominance.
Incomplete dominance refers to the phenomenon in which two true-breeding parents interbred to create an intermediate child (sometimes referred to as heterozygous). Alternate names for it include partial dominance and intermediate inheritance. In the case of partial dominance, the variations (alleles) are expressed in a reduced ratio rather than as dominant or recessive.
A new heterozygous phenotype is produced by imperfect dominance, often known as the dilution of the dominant allele relative to the recessive allele. For instance

A group of proteins in the thylakoid membrane that shuttles electrons between the proteins and other carriers is called an Electron transport chain.
In photosynthetic eukaryotes, the electron transport chain is observed on the thylakoid membrane. here, light energy drives electron transport through a proton pump and the ensuing proton gradient causes the next synthesis of ATP.
The light reactions are finished by means of the thylakoid membrane protein complexes photosystem II (PSII), cytochrome b6/f complicated, photosystem I (PSI), and ATP synthase. Many proteins that play crucial capabilities in both reactions have poor roles in viral pathogenesis.
The most outstanding thylakoid transporter is the proton-translocating ATP-synthase.
