Protists vary in structure and function more than any other group of organisms. However, here are some common traits: a.All have membrane-bounded organelles, and so are ___________________. b.Most are single-celled, or ___________________________. c.They get their food in several ways. Some contain chloroplasts and do photosynthesis, and so are considered __________________. Others ingest food particles and so are ____________________.
Answer:
a. eukaryotes
b. unicellular
c. autotrophs; heterotrophs
Explanation:
Protists represent a separate kingdom of eukaryotic organisms (ie., organisms whose cells have a nucleus). The most important features of protists include: 1- they are unicellular organisms, 2-contain mitochondria, 3-can be parasites, and 4-generally live in optimal conditions in moist or aquatic environments. In the past, protists were divided into Protozoa (animal-like organisms) and Protophyta (plant-like organisms), which nowadays we know are heterotrophic (also often parasitic) and photosynthetic protists, respectively.

Some organisms, such as bacteria, reproduce asexually; whereas, other organisms reproduce
sexually. Which statement correctly states why one type of reproduction is beneficial over the
other?
A. Asexually reproduced offspring are more genetically diverse.
B. Asexual reproduction produces offspring genetically different from parents.
C. Sexual reproduction can produce a large number of offspring very quickly.
D. Sexual reproduction produces organisms that are genetically diverse.
Answer:D
Explanation: A isn't right because during asexual reproduction there is no exchange of genetic characteristics thus the offsprings retain the genetic characteristics of their parents and there is no diversity.
Sexual reproduction on the other hand involves the fusion of gametes and the exchange of genetic characteristics thus the offsprings are diverse and are not identical to their parents as is the contrary in asexual reproduction.
Sexual reproduction produces organisms that are genetically diverse.
Sexual reproduction involves the combination of chromosomes from both parents. This combination of chromosomes introduces variation into the population. This combination does not occur in asexual reproduction.
Hence, the statement that correctly states why one type of reproduction is beneficial over the other is that sexual reproduction produces organisms that are genetically diverse.

The graphs show the reaction rate for an enzyme across a range of temperatures and pH. Based on these data, this enzyme functions best at what temperature and pH? *
The graph is attacged and the options is as follows:
Temperature of 27oC and a pH of 4
Temperature of 37oC and a pH of 6
Temperature of 40oC and a pH of 8
Temperature of 50oC and a pH of 10
Answer:
The correct answer would be - temperature of 37oC and a pH of 6
Explanation:
The graph 1 shows the relation between the rate of reaction for an enzyme and the temperature of reaction is been represented. In this graph the rate of eaction is highest (point from the slope starts decreasing) at the So, by the options and graph the temperature 37°C(Below 40°C) rate of reaction is maximum.
Similarly, in other graph rate of reaction and and pH has been represented in which rate of reaction is maximum at pH 6. after 6 pH the rate of reaction started decreasing.
Which statement best explains the relationship between cellular respiration and photosynthesis?
There is a multitude of evidence that supports how life has changed over time due to variation in the gene pool of different species. Which of the following choices below represents a scientific theory that explains these changes? *
A. As environments and ecosystems change over time, those that acquire suitable traits are more likely to survive and reproduce and the gene pool changes because organisms must adapt to survive and reproduce.
B. As environments and ecosystems change over time, those with variations for traits that are more successful in the new conditions are more likely to survive and reproduce, thus changing the allele frequency in the gene pool.
C. Because the environments and ecosystems show little change over time, organisms are already adapted for surviving in their given habitats for which they are made.
D. Because the environments and ecosystem show little change of time, the organisms that choose to adapt to different environments will migrate and become suited for new habitats.
Answer: A. Environmental drivers plus genetic variation in the population result in natural selection
Explanation: over geological time environmental conditions change. Organisms do not survive in one environmental niche with traits adapted to a possible future change that might suit those traits. Adaptation is not a matter of choice: adapt if possible or go extinct.
There is a (badly named) concept called pre-adaptation, which is that variations in some existing trait render adaptation to a different environment more likely.

Muticellular organisms, cells are organized into tissues, tissues into organs, organs into organ systems, and system into organisms.
Answer:
Explanation:
.
Carbohydrates like glucose can undergo spontaneous rearrangement to give an alternate configuration for the anomeric carbon when the ring is free in solution. However, when glucose is covalently attached to another sugar through C1, this rearrangement cannot occur. Consequently, the configuration of carbohydrate oligomers and polymers is fixed. Why can't glucose rearrange when in a polymer form?
Answer:
The presentation according to another circumstance is categorized in the following section.
Explanation:
Glucose constructs anomers because of the extreme involvement of flexible metal-carbon because that continues to exist as something of a monomer. However, when plastics are established, transformation is limited with glycoside formation of complexes among both anomeric carbon atoms.
Sucrose, besides obvious reasons, would be manufactured by glucose and fructose, which have been connected by something like a glycerol backbone involving glucose carbon atom as well as fructose. The mechanism including its creation of anomers even by movement through carbon becomes called "Mutarotation" Sucrose doesn't always show mutation.Which of these causes the day/night cycle on earth

Ground tissue
stores extra food
supports the plant
is found in plants and animals
Omakes up the majority of a plant
Dis responsible for photosynthesis
Answer:
stores extra food
is responsible for photosynthesis
supports the plant
makes up the majority of a plant
Explanation:
Ground tissues are one of the three types of plant tissues (others being dermal and vascular). They are composed of cells as follows: parenchyma, collenchyma, and sclerenchyma. These three cells that make up the ground tissues perform different functions in the plant cell.
- Parenchyma functions in photosynthesis and storage of extra food (carbohydrates) in the cell.
- Collenchyma functions in the support of young regions of the plant
- Sclerenchyma, which has the thickest cell wall, functions mainly in the strengthening/support of the plant cell.
Also, among the three tissue types in a plant, ground tissues make up majority of the plant cell.
