The right option is Parkinson's disease

Parkinson's disease (PD) is a neurodegenerative disorder caused by degeneration of dopamine-secreting neurons of the substantia nigra of the brain. Symptoms of PD generally develop slowly over years. An individual with PD may experience tremor which can occur in the form of bradykinesia , limb rigidity and gait and balance problems.

Answer:

i cant read from the picture

Explanation:

If 50% of males in a population dies then the birth rate will decrease to 50%.

For example in a population there are 100 males and birth rate is also 100 per year.

Then after disease only 50 males will remain to reproduce and 50 babies will birth in a year. Hence birth rate also decreased by 50%.

If 50% of females in a population dies then the birth rate will decrease to 50%.

For example in a population there are 100 females and birth rate is also 100 per year.

Then after disease only 50 females will remain to reproduce and they will give birth to 50 babies in a year.

Hence birth rate also decreased by 50%.

Yes, the death of both male and female affected the birth rate of the roaches.

Both male and female death affected the birth rate of roaches because male and female are required for the increasing and maintaining birth rate. Male mate with female produces offspring so male as well as female are necessary for the birth of baby roaches.

If male population becomes half or 50% so due to less mating less female produce less baby roaches which results in decrease of birth rate while on the other hand, if the female population reduced to 50 % then less females are available for producing baby roaches which also affect the birth rate so we can conclude that the death of both male and female affect the birth rate of the roaches.

The indigestible carbohydrates that are found in plant cell walls are called dietary fibers. Dietary fibers are group of complex carbohydrates that is found mostly in vegetables, fruits and legumes. They include beans, whole grains such as wheat, nuts etc. Dietary fibers cannot be digested in mammals because the body lacks digestive enzyme that is required to break them down.

Cellulose is the carbohydrate found in plant cell walls that is indigestible for mammals. It provides structural support to plant cells and is processed as dietary fiber in animals that cannot digest it. Herbivores rely on bacteria to digest cellulose with the enzyme cellulase.

The carbohydrate that is found in plant cell walls and is indigestible by mammals, including humans, is known as cellulose. This polysaccharide is a linear polymer made up of glucose units joined by ß-1,4-glycosidic linkages. It provides structural integrity to plant cells due to its rigidity and high tensile strength. Animals lack the proper enzymes, specifically cellulase, to break down these glucose units. As a result, cellulose passes through the digestive system of animals as dietary fiber. However, some herbivores, such as cows and horses, can digest cellulose because of symbiotic bacteria in their digestive tracts that produce cellulase. This enzyme helps break the ß-1,4 links, allowing these animals to use the glucose for energy.

Answer: Yes. Many brain tumors are due to metastasis.

Metastasis is the term used for cancer that spreads or travels to a different part of the body from its primary site (location where it started). Many brain tumors are due to metastasis.

Answer:

The answer is Truly, Many cerebrum tumors are because of metastasis.  

Explanation:

Metastasis is the term utilized for malignant growth that spreads or goes to an alternate piece of the body from its essential site area where it began. Many cerebrum tumors are because of metastasis.  Malignancies that initially began from lung, bosom, melanoma skin, colon and kidney commonly spread to the brain.

Generally Viruses undergo cell division and these membranes become the outer lipid bilayer known as a viral envelope.

The membrane is studded with proteins coded by the viral genome and host genome; the lipid membrane and any carbohydrates present derive exclusively from the host. Influenza and HIV viruses use this strategy.

The Michelangelo virus is a computer virus which is first discovered on 4th February 1991 in the regions of Australia. The virus was designed to infect DOS systems, but did not engage the operating system of the computer or make any OS calls through it. Michelangelo like all the boot sector viruses is operated at the BIOS level.

Michelangelo virus is classified as a boot sector virus, a virus which infects the startup sectors of storage devices usually the boot sector of a floppy disk or the master boot record (MBR) of a hard disk in a computer system.

Therefore, Generally Viruses undergo cell division and these membranes become the outer lipid bilayer known as a viral envelope.

Electronegativity is an element's ability to attract electrons within a chemical bond, increasing from left to right across a period and decreasing down a group in the periodic table. Elements with high electronegativity tend to be nonmetals, while those with low electronegativity are typically metals.

The electronegativity of an element indicates its ability to attract electrons when it forms a chemical bond. In the periodic table, electronegativity values increase from left to right, culminating with elements like fluorine, which possesses the highest value.

Conversely, as you move down a group, the electronegativity decreases due to the increase in atomic size, which makes the nucleus less effective in attracting bonding electrons.

Groups on the periodic table, labeled from 1 to 18, categorize elements with similar properties.

For instance, Group 1 contains the alkali metals, Group 17 the halogens, and Group 18 the noble gases.

These groups exhibit particular trends: as you move down a group, atomic radius and density increase, while electronegativity and ionization energy decrease.

Understanding these periodic trends is essential for predicting the chemical behavior of elements.

The ability to attract electrons dictates how elements will react with others, making electronegativity a key concept in the study of chemistry.

Final answer:

AUG is the only mRNA codon that corresponds to the amino acid methionine in the genetic code, encoding both the start of protein synthesis and methionine within the polypeptide chain.

Explanation:

Methionine is encoded by the codon AUG in the genetic code, which is universal across virtually all organisms. This codon has a dual function - it signals the start of protein synthesis and also encodes for the amino acid methionine itself within the sequence of a polypeptide. In prokaryotes, AUG can code for a modified form called formylmethionine (f-Met), when it is at the start of a protein sequence. However, for coding methionine within a sequence, the unmodified methionine is used. Despite the 64 possible codons in the genetic code due to the arrangement of the four nucleotides (adenine (A), uracil (U), guanine (G), and cytosine (C)) in triplets, methionine and tryptophan are unique in that they are each encoded by only one codon. In conclusion, there is only one mRNA codon that corresponds to methionine when it comes to protein synthesis, which is AUG.

Astronauts at the ISS are scientists primarily because they collect data to improve knowledge of space through research in various scientific fields in a unique microgravity environment (option B).

Astronauts who visit and stay at the International Space Station (ISS) are indeed scientists because they collect data to improve man's knowledge of space (option B). These astronauts carry out scientific research in a microgravity environment, which provides unique conditions for experiments in various fields such as biology, chemistry, physics, physiology, and medicine. The International Space Station serves as an advanced laboratory where astronauts can work on experiments that are not possible on Earth.

While traveling to space is a remarkable feat, the core of the astronaut's work on the ISS is rooted in scientific investigation. They may also be involved in repair missions or predicting weather on Earth using satellite pictures, but their primary role is to engage in research that advances our understanding of space and related sciences.

The urinary bladder is a hollow organ that collects and stores urine until it is expelled from the body through urination.

Its primary function is to collect and store urine from the kidneys before the urine is eliminated through urination.

Urine enters the urinary bladder from the ureters through two ureteral openings and leaves the bladder through the internal urethral sphincter, which relaxes to allow urine to flow out into the urethra, eventually being expelled from the body.

Key Features

The bladder can stretch to hold a significant volume of urine and is involved in urine storage until urination occurs, making it an essential organ in the urological system.

The correct answer is option (A) leaves > deer > wolf.

A food chain is a linear sequence of organisms through which the nutrients and energy flow as one organisms feeds on the other. They show organisms starting from the producers and end with consumers or sometimes with detrivores or decomposers. Each level of the food chain is called the trophic level. The producers which use solar energy and prepare their food occupy the first trophic level, followed by the primary, secondary, tertiary, quaternary consumers occupying the next trophic level.

In the food chain given above, leaves > deer > wolf, deers feed on the leaves which are maximum in number comparitively, wolf feeds on the deer which are comparitively more in number than the wolves. This is the correct sequence of food chain showing the tranfer of energy and decreasing number of organisms with subsequent increase in the trophic levels.

The light-dependent reaction is one of the two reactions of photosynthesis (other is light-independent) which occurs in the thylakoid membranes of organelles called chloroplasts.

The first one uses the energy of light to make molecules needed for the next stage of photosynthesis. Two molecules produced are the energy storage molecule ATP and the reduced electron carrier NADPH.

Answer and Explanation: To be inherited through mendelian genetics, the traits has to "follow" the 3 principles Mendel described:

1) Principle of Uniformity: All the progeny born from a cross between parents that differ by only one trait will appear identical. Exceptions to penetrance (probability of a gene being expressed), expressity (the different degree a trait express in each individual) and sex-linkage inheritance;

2) Principle of Segregation: The alleles are separated during meiosis, producing equal quantity of gametes (male and female) that contain each allele. So, when one parent carry the dominant trait, the offspring will have the same genotype from the dominant with ratio 3:1;

3) Principle of Independent Assortment: Alleles at one locus separate into gametes independently of alleles at other loci, i.e., each trait is inherited independently from the other. In a dihybrid cross, the proportion of dominant offspring is also approximately 3:1;

In conclusion, traits that follow these "rules", are traits inherited through mendelian genetics.

The group of organisms that are most similar genetically is the Genus. Organisms within the same genus share a closer genetic relationship compared to organisms in higher taxonomic groups.

The group that is made up of organisms that are most similar genetically is the Genus.

In the hierarchy of taxonomy, organisms are classified into different groups based on their genetic similarities. At the lowest level, organisms are grouped into species, and species that are most similar are grouped into the same Genus. Therefore, organisms within the same genus share a closer genetic relationship compared to organisms in higher taxonomic groups like Phylum, Order, or Class.
