What is the most distal interphalangeal joint?
How many carpal bones are in the wrist?
Answer:
"proximal interphalangeal joints" (PIJ or PIP), those between the first (also called proximal) and second (intermediate) phalanges.
"distal interphalangeal joints" (DIJ or DIP), those between the second (intermediate) and third (distal) phalanges.
our wrist is made up of eight small bones (carpal bones) plus two long bones in your forearm — the radius and the ulna. The most commonly injured carpal bone is the scaphoid bone, located near the base of your thumb.
Explanation:
The mitochondria is known as the “powerhouse of the cell." Why?*
glucose is broken down into cellular energy (ATP).
lipids release energy as they form polypeptide bonds.
glucose is created through the process of photosynthesis.
proteins create energy as they are converted from sugars.
Answer:
The correct answer is - glucose is broken down into cellular energy (ATP).
Explanation:
Mitochondria is the double membrane cell organelle presents in all eukaryotic cells that produce the energy by the process of cellular respiration from the food to the cell to perform its day to day functions.
The cellular respiration is the process that involves the braking of the sugars into simple molecules and these catabolic reaction produce energy with CO2 and water as waste. The energy is stored in the form of ATP which is generated in the inner membrane of mitochondria. ATP is used by the cell to perform its function.
Thus, the prower house of the cell is mitochondria.

Multiple choice.
The survival of a species depends on its ability to adapt to changes in the environment. A species must be capable of surviving and reproducing despite changes to food sources, climate, or threats from predators. Which statement correctly describes a way that mutations increase the likelihood that a species will survive in a changing environment?
A. Mutations are a source of variation in the species.
B. Mutations are the cause of disease in the species.
C. Mutations are not harmful when they occur in somatic cells of the species.
D. Mutations are always passed on to subsequent generations of the species.
Answer:
A
Explanation:
A. when there is a variation or mutation there might be the chance that they develop a way to eat plants that they normally would not be able to. If and when they survive they reproduce passing on the genes to there offspring and so on. if the mutation is bad then the animal will die therefore not passing on there genes.
The statement 'mutations are a source of variation in the species' correctly describes a way that mutations increases the likelihood that a species will survive in a changing environment (Option A).
Mutations are any alteration in the genetic material (nucleotide sequence) of the genome of an organism.Mutations can be beneficial, deleterious or neutral depending on the environmental conditions in which the individual suffering the mutation lives.Germinal mutations (i.e., mutations in the gamete cells) can be passed to offspring and thus increase the genetic variation of the species and/or population in which these mutations appear.In conclusion, the statement 'mutations are a source of variation in the species' correctly describes a way that mutations increases the likelihood that a species will survive in a changing environment (Option A).

A cross between a white rooster and a black hen results in 100% blue offspring. When two of these
blue offspring are mated, the probable phenotypic ratio seen in their offspring would be
A) 1:1:2 B) 3:1 C) 1:2:1
D) 2:1:1
Answer:
c
Explanation:
they each contain a gene from their father, their mother, and themselves, since they are both blue there will be 2 blue genes, 1 black and 1 white
A cross between a white rooster and a black hen results in 100% blue offspring, so when two of these blue offspring are mated, the result is 1:2:1, which is option c, as 1 is white, 2 are blue, and 1 is black.
What is the significance of the genetic crossing?Due to incomplete dominance, genetic crossing occurs between two animals, such as one black hen and one white rooster, and the offspring are blue. When these two heterozygous blue birds cross, a total of four hens and roosters offspring are formed: 1 is black, 1 is white, and 2 are blue and this genetic crossing can also increase genetic diversity within a population due to meiosis.
Hence, a cross between a white rooster and a black hen results in 100% blue offspring, so when two of these blue offspring are mated, the result is 1:2:1, which is option c, as 1 is white, 2 are blue, and 1 is black.

Myosin is plentiful in muscle cells, but is not found at all in lens cells. Lens cells contain large amounts of crystallins, which are not found in muscle cells. Why do some proteins appear in one type of cell but not in another?
Which 2 cells would be more genetically similar to each other?
The cell is the fundamental block of living organisms. Cells are of two types including Somatic cells and germ cells.
Somatic cells refer to all the cells of the body except for the germ cells or as a whole-cell in the case of the unicellular organism.The somatic cells are obliged to build the whole body parts.Somatic cells divide only by the process of mitosis.The germ cells are the generative cells liable for reproducing the offspring.Germ cells generate cells like sperm in males and eggs in females.Germ cells are the unique cells that undergo both mitosis and meiosis to produce gametes.The germ cells produce haploid (N) cells.Therefore, the two somatic cells of an individual will be identical as they carry the same genetic information.

5.21 Unit Test: Water and Oceans - Part 1
What forms as a result of the wind's frictional force on water?
O deep sea currents that move in a path opposite to the wind currents
O surface currents that move in a path opposite to the wind currents
surface currents that move in a path similar to the wind currents
deep sea currents that move in a path similar to the wind current
Answer:
Surface currents that move in a path similar to the wind currents
Explanation:
One of the reasons of the movement of the surface of the oceans is the force of the blowing wind. When there is a movement of wind over the surface of the ocean, the surface friction is created. Because of this there is an energy transfer between the force of the wind and the surface of the ocean water. This results in the creation of roughness of the surface of the ocean. The more the surface area of the ocean, the more is the transfer of the energy.

A. How do the oxygen (O2) and carbon dioxide (CO2) levels change over time?
Answer: How does CO2 level affect oxygen production? increasing CO2 production increases oxygen production. ... Greater flow of oxygen corresponds to a higher rate of photosynthesis.
Explanation:
Oxygen ( O₂ ) and carbon dioxide ( CO₂ ) levels change over time ;
Due to man-made and natural processes
Natural processes such as Photosynthesis and the storage of carbon in the biosphere and hydrosphere. cause a varying change in the levels of CO₂ present in the atmosphere because during photosynthesis CO₂ is used by green plants while the amount of stored carbon in the hydrosphere affects the level of available carbon in the atmosphere in general.
Man-made processes which includes the burning of fossil fuels and the release of CFC's into the atmosphere through gas flaring also the indiscriminate burning of bushes contribute immensely to the levels of carbon found in the atmosphere.
Hence we can conclude that Oxygen ( O₂ ) and carbon dioxide ( CO₂ ) levels change over time ; Due to man made and natural processes

The fact that the population of moths includes both brown and green moths is an example of variation.
What is Population?The population is the group of individuals belonging to the same species living in the same area at a particular time.
The population of moths consists of two types of genetic variations, which means there is an existence of two different alleles that are responsible for the expression of two different colours (brown, green) in the population of moths.
Therefore, the fact that the population of moths includes both brown and green moths is an example of variation.
