Answer 1
The answer would be true

Iron is an important substance that needed to create hemoglobin for red blood cells. A pregnant woman will produce more blood as prevention for the blood loss when laboring. The baby also need iron to makes their red blood cells. That is why the iron requirement increases in pregnancy.
About half pregnant woman doesn't meet the requirement iron from diet alone.

What is not a function of the skeletal system?


a) providing movement

b) protecting organs

c) storing minerals

d) making vitamins

Answers

Answer:

Making Vitamins

Explanation:

Final answer:

The skeletal system performs crucial functions such as providing movement, protecting organs, and storing minerals. However, it does not synthesize or generate vitamins. Other body parts such as the skin and gut bacteria are responsible for vitamin synthesis.

Explanation:

The skeletal system in our body performs several crucial functions, including providing structural support that enables movement, protecting our vital organs, and serving as a storage system for essential minerals like calcium and phosphorus. However, one task it does not carry out is the synthesis or making of vitamins. This is a function usually associated with other parts of the body, such as the skin (for Vitamin D synthesis) or the bacteria in our gut (for certain B vitamins and Vitamin K).

Answers

the myometrium is our correct answer. it is the middle muscular component of the uterine wall and it is not shed during menstruation. the endometrium is the inner mucosal coat of the uterus. it exhibits many characteristic changes during the menstrual cycle and all but its stratum basalis is shed during menstruation.

The layer of the uterus that is shed during menstruation is the endometrium.

The menstrual cycle causes hormonal changes in the endometrium, the uterus' innermost lining. If pregnancy fails, the endometrium sheds during menstruation, causing bleeding.

Menstruating women shed their endometrial lining every 28 days. After menstruation, the endometrium thickens again to prepare for egg implantation. Fertilisation and implantation implant the embryo in the endometrium.

Transplanting genetic material into bacteria is a simple task true or false

Answers

I think the above statement is true. Bacteria can exchange genetic material through; transformation where the bacterium takes up foreign DNA from its surroundings, Through transduction; where viruses carry bacterial gene from one bacterium to another, also through conjugation; where two temporarily joined bacteria directly transfer genetic material. 

Transplanting genetic material into bacteria is not a simple task; it is a complex process involving genetic transformation, genetic transfer, and bacterial conjugation. While competent bacteria can take up new DNA, creating transgenic organisms or introducing synthetic genomes into bacteria is more challenging and less straightforward.

Is Transplanting Genetic Material into Bacteria a Simple Task?

Transplanting genetic material into bacteria can be a complex process, as it involves several steps that need to be carried out with precision. Genetic transformation, genetic transfer, and bacterial conjugation are means by which bacteria can receive new genetic information. The introduction of recombinant DNA into a bacterium is facilitated through different mechanisms, such as natural competency, transformation, transduction, and conjugation using structures like the F pilus or sex pilus. As mentioned in LibreTexts, competent bacteria are able to take up DNA from their environment, and other methods may involve using plasmids or direct injection. Genetic engineering often takes advantage of these processes to introduce new genes into bacteria for the production of proteins or to create transgenic crops.

However, in the context of synthetic biology, the (booting) of a completely synthetic genome into a bacterial host presents a greater challenge and is currently a more complex and expensive process. Thus, the statement that transplanting genetic material into bacteria is a simple task is generally considered false.

What is luca cavalli-sforza's hypothesis for why skin color change came late?

Answers

Luca Cavalli-Sforza is a geneticist who hypothesized that the skin-color change came late because previous people had complete vitamin D access to the foods that they are eating. But the moment they started farming, the main vitamin sources are reduced, making a larger gain of having light skin.

Final answer:

Luca Cavalli-Sforza's hypothesis suggests that the change in skin color came later in European populations due to adaptation to reduced ultraviolet radiation exposure.

Explanation:

Luca Cavalli-Sforza's hypothesis for why skin color change came late is related to adaptation to changing levels of ultraviolet radiation. As humans migrated from Africa to areas with less exposure to UV radiation, their skin pigmentation became lighter in order to compensate for the reduced absorption of Vitamin D, which is necessary for bone health and immune function. Cavalli-Sforza's hypothesis suggests that this adaptation occurred later in European populations compared to those in other regions.

adaptive immunity is based upon ________.

Answers

Adaptive immunity is based upon the interactions between specific immune system cells and a specific antigen. This happens when cell surface of B cell binds to antigen thus lead to activating B cells. Hope this is the answer and this would help.
Answer:

Adaptive immune system is based on immunological memory.

Explanation:

This system is a specialized sub system of immune system that can eliminate pathogens and prevent their growth in the body.

After its first encounter with the pathogen, it creates an immunological memory that can last up to lifetime and it is highly specific. The memory of the first encounter leads to enhanced response in future with the particular pathogen.

For example, a person who gets affected from measles gets a lifetime protection from the pathogen.  

according to the second law of thermodynamics, which is a requirement for the thermal energy to flow from colder objects to hotter objects?

Answers

Answer: work must be done on the system

Explanation:

The second law of thermodynamics is the fundamental law of nature; it states that energy can be transferred from cold objects to hot objects only, if work is done on the system. If energy is added to the system then as a result the thermal energy would increase. Second law of thermodynamics is used to determine whether a process is spontaneous or not.
