Which statement best defines a protist?

Biology
1 answer:
Helga [31]4 years ago
8 0
Protists obtain food in 3 ways. They produce their own organic molecules, ingest, and absorb.  Ingestive protists ingest food, or engulf bacteria. These protists extend their cell wall and cell membrane forming a food vacuole around the food item. Inside the food vacuole, enzymes digest the food. Absorptive protists on the other hand, absorb food molecules  across their cell membrane which takes place through diffusion. Absorptive protists play a key role in decomposition. They are considered as important decomposers. Major producers  like photosynthetic protists  use light energy to manufacture  their own food.<span>

During photosynthesis , plants capture light energy from the sun to break the bonds in reacants, such as carbon dioxide and wate
riadik2000 [5.3K]

Answer:

Glucose (sugar)

Explanation:  

We know that plants take in carbon dioxide and returns it in a form of oxygen. For the plant to be able to make oxygen they need to get power. The power is the sun rays and that is mixed with the CO2, making glucose. Anything that uses photosynthesis is a producer, so it makes its own food.

Which best describes a difference between prokaryotic cells and eukaryotic DNA?
finlep [7]

Answer:

C

Explanation:

A prokaryotic cell does not have a nucleus, unlike in a eukaryotic cell. Instead it has something analogous called a nucleoid – a region where most of its genetic material can be found in the cell but is not membrane-bound. Organelles in a prokaryote cell are also NOT membrane-bound, unlike in a eukaryotic cell.

Usually prokaryotes have circular DNA while eukaryotes have linear DNA. In addition the eukaryotic DNA is complex with various noncoding regions called introns in addition to the coding regions (exons). Prokaryotic DNA, on the other hand, is simple with mainly coding regions.

Genetic engineering is the process of manipulating genes for practical purposes. Today, scientists have genetically engineered m
Maslowich

Genetic engineering is the process of manipulating genes for practical purposes. today, scientists have genetically engineered many types of organisms including crop plants. which of the following is a current benefit gained from genetically engineered crops? a. some genes can be transferred to wild plants in the area. b. some animals develop allergies to the genetically engineered crops. c. some food staples, such as rice, contain more nutrients. d. some disease resistant fruits and vegetables are less flavorful.

Answer:

. b. some animals develop allergies to the genetically engineered crops. c. some food staples, such as rice, contain more nutrients

Explanation:

Rice is global staple food. It is mostly affordable by the poor and peasant farmer wordwilde.Vitamin A is an important vitamin for good eye sight and also for boosting the  immunity.

This useful vitamin is  present in eggs, cheese and liver. Which are expensive for poor families Some small quantity are produced as carotene found in carrot. However, a precursor of Vitamin A called Pro-vitamin A carotenoids  is present in the part of rice called the Aleurone layer.

However this part of the rice is not in the endosperm thus the vitamin are washed way during processing of white rice .Although this is present in brown rice. Basically, the energy storage in most crop seeds is stored in the endosperm. Thus the vitamin in the rice are not stored are therefore not imbibe during consumption.

Therefore in order to incorporate  carotenoid into the endosperm to avoid been wasted, Daffodil was used. The genes for the transcription of carotene in daffodils and from  particular soil bacteria called Pantoea Anantis were extracted, to transfer carotenoid into the rice endosperm. This is called the Golden rice,, because the rice appear golden from the incorporation of the carotenoid into the endosperm though genetic engineering. This appear orange from the carotene pigment present in the endosperm.

Thus from the consumption of the rice ,poor family could imbibe vitamin A into their diet.
