A ___(J)_____ is a group of individuals of the same species that mate and produce offspring. In each generation, new genotypes occur that express themselves as specific individual ____(K)___. Any factor that affects the ____(L)___ of a population can change the frequency of ___(M)___, resulting in evolution over time. Through the processes of variation and ___(N)___, new species can arise. A ___(P)___ is a population of physically similar, interbreeding organisms that do not interbred with other such groups.
Answer:
(J) population; (K) phenotypes; (L) gene pool; (M) alleles; (N) natural selection; (P) species
Explanation:
A population is a group of organisms living in a particular geographical area that is capable of interbreeding, while a species is a group of populations that are capable of interbreeding and producing fertile progeny. In a population, genetic variation can enter from one of these sources: 1-recombination (i.e., the exchange of DNA between homologous chromosomes during meiosis), 2-mutations (i.e., genetic alterations resulting from DNA replication), 3-migration of individuals between populations, or 4-lateral or horizontal gene transfer (i.e., the acquisition of genetic material between individuals without direct vertical inheritance, it is extremely rare in higher organisms). Alleles are gene variants which are may be created, for example, through mutation, while the gene pool refers to the total genetic diversity (i.e., alleles) that exists within a population. Finally, natural selection refers to the evolutionary process of differential reproduction and survival through which populations adapt and change.

Why does the skeleton stop growing in length?
a
Because the cartilage in the growth plate has been
replaced by bone.
b
Because there is not enough calcium and other
nutrients in the body.
Because the growth plates stop working
d Because the bones reach their maximum length
Answer:
Bones increase in length because of growth plates in the bones called epiphyses. As puberty progresses, the growth plates mature, and at the end of puberty they fuse and stop growing. ... After the growth plates fuse, there is no more increase in height, and we all then shrink gradually as we get older.
The body can be invaded by (mutagens / bryophytes / tracheophytes / pathogens), which are harmful microorganisms that cause (infectious / chronic / malignant / proactive) diseases. The body then initiates a(n) (homeostasis / feedback / inflammatory / inhibition) response, which may involve redness, swelling, and fever.
Answer:
1. Pathogens
2. Infectious
3. Inflammatory
Explanation:
A pathogens is any disease-causing microorganism or agent. Pathogens such as bacteria, virus etc. invade the body of a living organisms and cause an abnormal state of health (disease) in such organism. The diseases caused by pathogens are usually infectious, meaning that it can spread from one individual to another.
This attack by pathogens triggers an inflammatory response by the body of the host. This inflammatory response is visibly characterized by redness, swelling, and fever etc.
: Is a human leg prosthetic an example of science or technology? Explain your answer.
QUICK!!!! ANSWER PLEASE WITH EXPLANATION TOO!!!
Answer:
This would be an example of technology.
Explanation:
Artificial limbs, or prostheses, are used to replace a missing body part which may have been lost due to trauma, disease or congenital defect. The type of prosthesis a person can use is dependent on the individual, including the cause of amputation or limb loss, and the location of the missing extremity. These come in all shapes and sizes, for whatever you need.
Have a nice day!
Answer:
A technology, since the actual prosthesis is a human creation that solves a problem. Science is nothing physical. It is the combination of laws and theories that explain our universe and helps us make decisions. We don't really invent science, we describe it.
Science is ideas. Technology is human creations.
Science generally underpins all new technology.
In your human leg prosthesis example science is crucial in choosing (or developing) suitable materials for construction of the prosthesis. The material must be relatively stable, not break down into toxic substances and have good durability. Knowledge of human Biology is also important if you want to start replacing human body parts.
Basically chemistry and biology are important in the prosthesis development. There is also probably physics regarding tensile strength requirements.
The actual end result of the human prosthesis is a technology which solves a problem of degraded human parts.
So to reiterate, it is a technology.

The student is studying the movement of substances across the cell membrane. She understands that some substances combine with special transport proteins to be carried across the cell membrane. The substances can move only from an area of higher concentration to one of lower concentration. This process is known as:
Answer:
Facilitated diffusion
Explanation:
Facilitated diffusion is the transport of hydrophilic molecules that can not freely cross the membrane. Channel protein and many carrier proteins are in charge of this transport. When uncharged molecules cross the membrane, they do it according to their concentration gradients, going from the more concentrated side to the lower concentrated one. When ions need to cross the membrane, the process depends on an electrochemical gradient.
Facilitated diffusion is a passive transport process because they only depend on electrochemical gradients, so they do not need any energy to occur.

Please choose the answer that best completes the blanks of this sentence in the correct order. The ______ plate method involves spreading an inoculum onto the surface of a plate in a pattern that results in isolated colonies in some areas of the plate after incubation, whereas the ______ plate method involves diluting an inoculum into several melted agar tubes and then adding their contents into plates for solidification and incubation.
Answer:
streak, pour
Explanation:
The streak method is the most popular technique used to isolate specific bacteria from a sample containing different microorganisms. In this technique, a sterile loop is employed to obtain an uncontaminated microbial culture. Colony picking refers to the process where colonies of pure bacteria are selected in order to duplicate them by transferring them into new agar plates. Moreover, the pour plate method is the most popular technique employed to count the number of colony-forming bacteria (i.e., bacteria/ml) in a specimen. The pour plate method consists of dropping the sample on a sterile plate and subsequently molten-cooled agar is then poured into the plate and mixed well with the inoculum.
Answer:
streak, pour
Explanation:
The streak plate method involves spreading an inoculum onto the surface of a plate in a pattern that results in isolated colonies in some areas of the plate after incubation, whereas the pour plate method involves diluting an inoculum into several melted agar tubes and then adding their contents into plates for solidification and incubation.
Which statement explains why the structure of sickle cells differs from normal red blood cells?
a. The gene mutation affected protein synthesis.
b. The gene mutation prohibited DNA replication.
c. The gene mutation inhibited the cell's ability to produce tRNA.
d. The gene mutation affected the cell's ability to produce ATP.
Answer:
A. the gene mutation affected protein synthesis
Explanation:
Basically, sickle cell results due to point mutation (change in one nucleotide) in DNA, which in turns affects the mRNA produced and finally the protein made from that mRNA is affected. I have listed a helpful image below which shows that the mutation actually results in formation of an undesired protein which causes sickle cell to occur.

Capillaries b) Thin-walled blood vessels that are less elastic than arteries c) Thick-walled, muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles d) Small arteries that deliver blood to capillaries e) Small vessels that connect the capillaries to the veins
Answer:
Arterioles - D
Arteries - C
Veins - B
Capillaries - A
Venules - E
Explanation:
This question is describing the blood vessels that make up the circulatory system. The blood vessels with their accurate description are as follows:
- ARTERIES: Arteries are the most elastic and thick-walled blood vessels that functions to carry blood away from the heart using great pressure. Arteries are muscular, flexible tubes that carry oxygenated blood away from the heart to the arterioles.
- VEINS: Veins are blood vessels that carry deoxygenated blood back to the heart. Veins have a thin wall and are less elastic in comparison with arteries.
- CAPILLARIES: Capillaries are smallest blood vessels designated to connect the smaller arteries or arterioles to venules. They are also thin-walled.
- ARTERIOLES: Arterioles are small arteries or branches of an artery that connects the arteries to capillaries. Arterioles deliver blood to capillaries.
- VENULES: Venules are tiny veins or branches of a vein that connects the veins to the capillaries. Venules deliver blood from capillaries to veins.

Mold is made up of many fungi cells. Mold would be considered what type of organism?
A. unicellular
B. prokaryotic
C. multicellular
Answer:
The answer is Multicellular
Mold would be considered a multicellular organism, which is made up of many fungi cells.
When it is said that living beings are made up of cells, what is meant is, if they are multicellular organisms.
Eukaryotes include all members of the animal and plant kingdoms, including fungi, which exist both in multicellular forms (molds) and in unicellular forms (yeasts), and protozoa, which are exclusively single-celled.
About multicellular organism molds:
The filaments that make up the mycelium are called hyphae. The hyphae may be separated into generally multinucleated sections by means of perforated septa, or may be absent.The cell wall of the mycelium of molds resembles an extensive tubular system through which the cytoplasm advances to disperse and search for nutrients.Therefore, we can conclude that mold would be considered a multicellular organism, which is made up of many fungi cells.
