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

Answers

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.

Polar bears will go extinct by the end of the 21st century.

Explanation:

Polar bears live at the North Pole. Due to global warming, the ice at the poles is melting at an alarming rate. Soon there won't be any glaciers. Without the ice Polar bears will lose their home. The climate on Earth is becoming warmer day by day. So even if the Polar bears survive they will not be able to adapt to the warmer climate. Thus leading to their extinction.

: Is a human leg prosthetic an example of science or technology? Explain your answer.
QUICK!!!! ANSWER PLEASE WITH EXPLANATION TOO!!!

Answers

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 ______ 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.

Answers

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.

The following RNA strand was produced: 5 AUG GCG UUU 3 Which of the following DNA strands could have been the template for this RNA? Choose 1 answer: A 3 TAC CGC AAA 5' 3' CGT TAT GGG 5' 3' AUG GCG UUU 5' 3' UAC CGC AAA 5​

Answers

Answer:

A

Explanation:

Each nucleotide is appropriately paired according to the A-U/T-A and C-G pairing rules, so these are complementary strands.

The DNA strand that could have been the template for RNA 5' AUG GCG UUU 3' is 3' TAC CGC AAA 5'.Thus, the correct option is A.

What is a Template strand?

A template strand may be defined as the DNA sequence that can duplicate itself during the process of mRNA synthesis. During this process, the cell utilizes a non-coding/antisense DNA sequence as a template to construct mRNA.

The production of the mRNA strand is done with the help of complementary base pairing with that of the template strand. In this process, A is bound to T and vice versa, while C is bound to G and vice versa.

In mRNA, the Thymine (T)  is replaced by Uracil (U). According to Chargaff's rule, the amount of ADENINE is equal to THYMINE, while the amount of GUANINE is equal to CYTOSINE.

Therefore, it is well described above.

Answers

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.

Answers

Answer:

the classification of racial types is an arbitrary, culturally specific process.

Explanation:

Racism can be defined as an act, practice or policy by an individual, group of people or institutions which typically involves promoting the ideas and belief that a race is superior in comparison with another. Thus, it simply means the believe that a particular race has dominance over another (an inferior race).

An examination of the classifications of races from around the world indicates that the classification of racial types such as Africans, Americans, Indians, Asians, Black-Americans, Hispanics, etc., is typically based on individual perception, not objective and an impulsive (arbitrary), culturally inclined or specific process.

This ultimately implies that, the classification of racial types is considered not to be based on any form of objective distinction but may be defined by a person's culture.

A culture can be defined as the general way of life of a group of people living together in a particular location or society.

Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.

So, she also multiplied the original value for green paint by 5 to get the new value for green paint. There are multiplicative relationships, relationships related to multiplication, in a ratio table. To get from values for green and black in one ratio to values for green and black in another ratio, we can multiply both the initial values by the same number. For example, to get from the ratio 3:2 to the ratio 6:4, we multiply both the 3 and 2 by 2. And to get from the ratio 3:2 to the ratio 15:10, we multiply both the 3 and 2 by 5.Sometimes, there are also relationships related to addition, called additive relationships, in a ratio table. To get from one value for green to another value for green, we can add 3. To get from one value for black to another value for black, we can add 2. When using the multiplicative relationship to find equivalent ratios, we can multiply both columns by the same number. But when using the additive relationship, we cannot add the same number to both columns.A cookie mixture requires 3 teaspoons of sugar for every 4 teaspoons of salt. You want to triple the mixture.
