How is biology related to midwifery

Answers

The relationship between biology and midwifery is that midwifery is a branch of biology that deals with child delivery.

What is midwifery?

Midwifery is the practice and science of being a midwife, which is a person, usually a woman, who is trained to assist women in childbirth, but who is not a physician.

On the other hand, biology is the study of all life or living matter. It is the all-encompassing branch of science that deals with life.

Midwives deal with human lives, hence, is related to biology in that aspect. While studying to become a midwife, biology is an integral and compulsory subject to undertake.

Therefore, it can be said that both biology and midwifery are concerned with lives.

Carbapenems are b lactam antibiotics, as are penicillins and cephalosporins, which work by inhibiting cell wall biosynthesis in bacteria. In recent years, more cases, mostly in patients who have been hospitalized for a long period of time, of bacteria showing resistance to Carbapenems have been reported. In these patients, this drug could no long control bacterial infections. Check ALL the statements that are correct:



Question 1 options: Bacteria that are resistant to Carbapenems did not exist before these drugs were used.
Carbapenems are the selecting agent Bacteria become resistant only after they come into contact with Carbapenems
This development of drug resistance by bacteria is an example of evolution
Non-resistant bacteria become resistant strains via mutation
The rate of mutation (to resistant strains) is always increased by the use of Carbapenems
The rate of survival among resistant bacteria is always increased by the use of Carbapenems
The change from non-resistant to resistant bacterial strains are not due to changes in genes.
Cabapenem-resistant bacteria may come into existence if Carbapenems are not used.

Answers

Only once bacteria come into touch with carbapenems do they develop resistance. This bacterial drug resistance is an illustration of how non-resistant bacteria can mutate into resistant strains.

The original "carbapenem," thienamycin, would become the parent or model compound for all subsequent carbapenems. Recent research demonstrates unequivocally that carbapenem resistance is growing globally. In particular when porin losses occur, excessive synthesis of weak carbapenemases as CMY-10 and PDC Beta-lactamases might result in carbapenem resistance. Gram-positive bacteria develop resistance to carbapenems and other beta-lactam antibiotics through mutation-derived modifications to their PBPs, whereas Gram-negative bacteria frequently enlist the help of additional defense mechanisms to combat the effects of these drugs.

1. What is the change in volume from 22 degrees Celsius to 23 degrees Celsius?

Answers

Answer:

According to Charles' Law.

Volume is directly proportional to Temperature.

So if temperature increases from 22degree Celsius to 23degree Celsius, then Volume will increase from its initial.

The change in volume from 22 degrees Celsius to 23 degrees Celsius is seen because the change in temperature is directly proportional to the change in volume and the volume increases.

What is the role of temperature?

The role of temperature is important as the low temperature changes the state that is from the liquid to the solid while the high temperature changes the state of matter that is from the liquid to the gas. The temperature of the earth is continuously increasing, so that the polar ice is melting and the water level on the earth is increasing. The increase of one degree is significant in the earth as the ice melts into the water, and that harms the animals and plants present in the different habitats.

Hence, the change in volume from 22 degrees Celsius to 23 degrees Celsius is seen because the change in temperature is directly proportional to the change in volume and the volume increases.

Is the C. They line up with the duplicated chromosome one on top of the other

Chromosomes line up differently in meiosis compared to mitosis as they line up with the duplicated chromosome one on top of the other. Therefore, the correct option is C.

During mitosis the chromosomes align differently than during meiosis. Homologous chromosomes pair up and join during the first stage of meiosis, known as prophase I. Two sister chromatids, which are identical copies made by DNA replication, make up each homologous chromosome. A quadrivalent or bivalent is the name of the structure formed by these paired homologous chromosomes.

The order the organisms will appear during primary succession would be lichens -->mosses-->grasses and annual flowers--->bushes and shrubs-->trees.

What is succession?

Succession refers to the gradual changes to the community of organisms in an ecosystem until a stable community is reached.

Succession can be primary or secondary.

Primary succession happens when a community that has never held any life before gets newly colonized by life.

Secondary succession happens when a community that already holds life experiences a major disturbance and needs to start adjusting itself to resume changes again.

The colonizers in primary successions are called pioneer species. Due to limited nutrients and soils, pioneer species must have low requirements.

Thus, the order of appearance during primary succession would be the order or increase in growth requirements.

What is the scale of the model?
A. 1:1
B. 1:25,000
C. 10:25
D. 2,500:1

Answers

Answer:

B

Explanation:

I guessed and I got it correct

The scale of the model is 1:25,000. So, the correct option is B.

Scale models are used to represent things or places at a smaller, more manageable size while maintaining proportionality. They are often employed in many different disciplines including geography, engineering and architecture.

By comparing the length of the model to the length of the actual river, one can estimate the scale of the model.

The scale can be determined by dividing the length of the actual river by the length of the model, where the model is 1 m long and the actual river is 25,000 m long:

Scale = Length of actual river / Length of model

Scale = 25,000 m / 1 m = 25,000

Therefore, the scale of the model is 1:25,000. So, the correct option is B.
