Answer: 2. the production of new body cells to replace old cells
Mitosis is a form of cell division that results in two daughter cells that are identical (genetically) to each other and to its original cell. It plays a vital role in the life cycle of most living things.
In single-celled (unicellular) organisms such as bacteria, mitosis is a type of asexual reproduction, making identical copies of a single cell.
In multicellular organisms, mitosis produces new cells to replace old cells and promote growth and repair.
Answer:
The production of new body cells to replace old cells;
The production of additional embryonic cells following fertilization.
Which of the following groups is made up of organisms that are most similar genetically
A. Phylum
B. Order
C. Class
D. Genus
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.
Explanation: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.

Some non-communicable diseases (ncds), including Parkinson’s disease, begin with impaired motor control.
Answer: Option C
Explanation:
It is caused mostly due to genetic or environmental factors. Parkinson’s disease is a neural disorder caused by deterioration of motor function in the brain. Dopamine cells are lost in the brain cells.
This dopamine in the brain is responsible for the smooth movement. When it is lost due to various factors it causes progressive loss of muscle control. This causes shaking, shivering, trembling of head and limbs.
How would you know if your results from experiment 2 show that the traits were inherited through mendelian genetics?
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.

i cant read from the picture
Explanation:
Imagine a disease that kills 50% of the male roaches i a population. do you think this would affect birth rate? briefly explain. 3. if a disease instead killed 50% of females, would it likely affect birth rate? briefly explain.
If 50% of males in a population dies then the birth rate will decrease to 50%.
Explanation: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%.
Part 2.If 50% of females in a population dies then the birth rate will decrease to 50%.
Explanation: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.

Generally Viruses undergo cell division and these membranes become the outer lipid bilayer known as a viral envelope.
What is the material by which viruses are surrounded?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.

Which sequence shows the correct order of living things in a food chain?
A. leaves > deer > wolf
B. salmon > insects > black bear
C. hamster > parakeet > dog
D. berries > moose > snake
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 result of the light-dependent phase of photosynthesis is the generation of which two energy-rich molecules?
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.
which carbohydrate is found in plant cell walls and is indigestible for mammals and other animals ?
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.
Explanation: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.

Why is the base of an energy pyramid wider than the top? *
A. There are usually many more producers than top predators in an ecosystem.
B. Only a small portion of energy can be passed from a lower level to the level above it.
C. Both A and B are true.
D. Neither A nor B is true.
The base of energy pyramid is wider than the top as there are usually many more producers than top predators in an ecosystem and also only a small portion of energy can be passed from a lower level to the level above it. The correct option is C.
What is energy pyramid?An energy pyramid, also recognized as a trophic or ecological pyramid, is a schematic illustration of the energy contained within an ecosystem's trophic levels.
The producers are at the bottom and largest level of the pyramid, and they contain the most energy.
Because there is less energy available to support those organisms, the number of organisms at each level decreases relative to the level below.
Because it contains the least amount of energy, the top level of an energy pyramid contains the fewest organisms.
Energy pyramids are always upright because energy is lost at each trophic level; an ecosystem that lacks sufficient primary productivity cannot exist.
Thus, the correct option is C.

The proteins necessary for life are assembled by the ribosomes of cells. These proteins include enzymes, which are proteins that can reduce the activation energy needed for certain chemical reactions. One very important role that enzymes play in eukaryotic cells is to allow energy production to occur by catalyzing the chemical reactions involved in cellular respiration.
Suppose an enzyme that is involved in cellular respiration is assembled by a ribosome. Where will this enzyme need to be transported in order to perform its function?
A. to the nucleus B. to a chloroplast C. to a vacuole D. to a mitochondrion
Final answer:
Enzymes involved in cellular respiration need to be transported D. to a mitochondrion to fulfill their role in ATP production.
Explanation:
An enzyme that is involved in cellular respiration will need to be transported to the mitochondrion to perform its function. This is because the mitochondria are known as the "powerhouses" of eukaryotic cells, responsible for producing adenosine triphosphate (ATP), the cell's main energy-carrying molecule. Cellular respiration occurs within the mitochondria where substrates are broken down to produce ATP. Proteins synthesized by ribosomes that are destined for the mitochondria are shuttled to these organelles post-translation. Ribosomes on the rough endoplasmic reticulum generally produce proteins that are meant for the cell membrane, but some proteins, particularly those involved in cellular respiration, are directed to the mitochondria where they execute their enzymatic functions.
