Protist reproduction
solong [7]

Answer:

e. is mostly asexual, with sexual as a second option.

Explanation:

Protist are unicelluar eukaryotic  microorganims. Example include:

<u><em>Amoeba</em></u> <u><em>proteus</em></u>

<u><em>Euglena</em></u><em> </em><u><em>viridis</em></u>

Dinoflagellates, etc.

Among the species of Protists, each species exhibit a unique way of reproduction. Generally, in Protist there are two types of reproduction, these are asexual reproduction and sexual reproduction. With asexual reproduction being the primary mode of reproduction in most protists.

Protist reproduce asexual by binary fission or by budding.

Binary fission occurs when a single protist divides its nucleus and then divides itself into two separate organisms.

Budding occurs when a new organism grows from the body of the parent organism. The new organism may separate from the parent or remain attached, forming colonies.

They also reproduce sexually by conjugation.

Sexual reproduction by conjugation requires two parent organisms contributing to the genetic material of the offspring. The essence of conjugation is to produce a new offspring with a wider genetic variability i.e the offspring being genetically different from the parent organisms.

SpyIntel [72]

Answer:

The way to figure this this type of question out is card by card. So the first card in the second hand is 2 in 52 (It can match either of the cards in the previous hand). × 1 in 51 ( it has to match the card that was not matched by the first card and there are 51 choises left). So 2 in 52 = 1 in 26 x 1 in 51 = 1 in 26 x 51 = 1 in 1326

Hope this helps! Remember to reword it incase your teacher checks for plagiarism! I recommend Quillbot to help!

Answer:

Bet

Explanation:

1. The radiaton from the X-ray waves can be harmful

2. Lack of resources comes on part of both the provider as well as the patient as the provider may not necessarily have the appropriate equipment or updated technology yet to detect such conditions such as in smaller town hospitals or even the patient may not have the financial or transportation resources in order to obtain these. Another one but while being a little subjective I think could even be a lack of knowledge on both of our parts as well as healthcare providers don't always have all the answers to everything let alone the resources as mentioned earlier or even perhaps the patient doesn't know the earlier signs and symptoms of certain cancers and even more so some cancers are VERY difficult to detect, especially until its too late.

3. X-ray imaging creates pictures of the inside of your body. The images show the parts of your body in different shades of black and white. This is because different tissues absorb different amounts of radiation. Calcium in bones absorbs x-rays the most, so bones look white

4. An X-Ray will be neccesary, ultrasounds exam organs while x-rays examine bones
