Answer:
The correct answer is villi.
Explanation:
The carbohydrates consumed by human beings are further dissociated into its mono forms, that is, fructose, glucose, and galactose. Of these monosaccharides, about 80% is glucose, which gets absorbed with the assistance of absorptive cells in the small intestine. In the walls of the small intestine, the food after digestion is passed into the blood vessels via the process of diffusion.
The mucosa or the inner wall of the small intestine is enveloped by finger-like tissues known as villi that further comprise microscopic finger-like outcrops called microvilli. These villi and microvilli enhances absorption of nutrients as they increase the surface area of the small intestine. Thus, the absorption of glucose within the small intestine is enhanced by the presence of villi.

What condition is required for fermentation to occur? A. When oxygen levels within a cell are too low for aerobic respiration B. When the energy production cycle ends of the Krebs cycle C. When a glucose molecule needs to break down completely D. When 20 molecules of ATP are needed\
Answer:
A. When oxygen levels within a cell are too low for aerobic respiration
Explanation:
Fermentation is a chemical or metabolic process that occurs in organism, when a carbohydrate such as glucose is metabolized or converted to an alcohol anaerobically (absence of oxygen).
When an organism lacks oxygen within the cell, aerobic respiration would be halted, hence pyruvate produced from glucose further undergoes fermentation anaerobically.
Organisms like lactic acid bacteria and yeast carry out fermentation. The process of fermentation is widely used in food industries, such as in brewing of wine or manufacture of yogurt.
Describe/draw/label in detail the process of Transcription & Translation. Make
sure to identify all key items and their roles.
Answer:
Through the Transcription & Translation, protein is synthesized
Explanation:
In the process of transcription, DNA is copied to mRNA. It is the mRNA that carries information about the protein synthesis. It has two steps – a) Formation of pre messenger RNA with the help of RNA polymerase enzymes and b) Edition of pre messenger RNA to produce desired RNA known as splicing.
In translation, mRNA is transported out of nucleus to the ribosome for the synthesis of proteins. tRNA is required for transportation.

Hii!! (: The correct answers are:
Asymmetry- A body plan that lacks symmetry
Bilateral Symmetry- a body plan made of two equal halves that mirror each other
Radial Symmetry- a body plan that is organized around a central point
Vertebrate- an animal with a backbone
Invertebrate- an animal without a backbone
A bodily layout with no symmetry is called asymmetries. A body plan with bilateral symmetry has two equal halves that are mirror images of one another.
What is Symmetry?A body plan that is structured around a central point is known as radial symmetry. Vertebrate: a backboned animal. An animal without a backbone is an invertebrate.
In biology, symmetry is the ordered repetition of parts in an animal or plant. In more detail, symmetry refers to a correspondence of bodily components on opposing sides of a dividing line or spread around a central point or axis that match in size, shape, and relative location.
With the exception of radial symmetry, exterior form and interior anatomy are rarely related because the same sort of symmetry can exist in animals with quite distinct anatomical structures.
Therefore, A bodily layout with no symmetry is called asymmetries. A body plan with bilateral symmetry has two equal halves that are mirror images of one another.

5. The occurrence of large or small beak sizes among seed crackers in the absence of
medium sized beaks is an example of
I
a. directional selection.
b. stabilizing selection.
c disruptive selection.
d. none of the above.
Answer:
Disruptive selection
Explanation:
Disruptive selection favors both of the extremes ( large and small beaks) Thank me later:)
The occurrence of the large or small beak sizes among the seed crackers is the illustration of disruptive selection.
What is disruptive selection?It is the kind of natural selection, which is bimodal and favors both the extremes traits within a population. It is a kind of natural selection, which opts against the average individual within a population. This kind of selection would show the phenotypes demonstrating both the extremes, however, exhibit very less individuals in the middle.
A classic example of disruptive selection is the size of the beak of the finches on the Galapagos Islands. As the majority of the seeds found these islands were either small or large, therefore, finches with small and large beaks were favored on those islands.
Thus, the correct answer is option c, that is, disruptive selection.

A student was observing slides of cell division. In one of the slides, he noticed loosely coiled chromatin depicting DNA duplication. Which phase of the cell cycle could it be?
A.
S phase
B.
Metaphase
C.
M phase
Answer:
A. S phase
Explanation:
The cell cycle involves all the series of division events that occurs to an organism. Cell division, which can be meiosis or mitosis, involves two main stages viz: Interphase and M phase.
Interphase describes the resting stage of the cell i.e. when the cell is not dividing. The cell uses this time to prepare itself for the next round of division. Interphase stage further consists of three main phases viz: G1, S and G2 phases.
In the S phase or synthesis phase of Interphase, the cell duplicates its genetic material (DNA). Hence, an onion cell observed by a student to have loosely coiled chromatin depicting DNA duplication is in the S-PHASE.
How is water introduceed into rivers and streams
Answer:
As the water flows down, it may pick up more water from other small streams, springs or or from rain or snow melt. ... Small rivers and streams may join together to become larger rivers. Eventually all this water from rivers and streams will run into the ocean or an inland body of water like a lake.Water can be introduced into rivers and streams through surface runoff, springs, groundwater discharge, melting ice and snow, and precipitation. ... The water at the source of the river has high oxygen content, but the width and depth are typically less than they are in the middle sections. The most simplistic answer is that all the water in a river comes from the sky—and that is certainly true, as streamflow is one part of the water cycle. It is also true that most of the water flowing in rivers comes from precipitation runoff from the surrounding landscape (watershed).

Two heterozygous purple-stemmed plants are grown. Each parent has the genotype ANL/anl. Pollen from one of the plants is used to pollinate the other, and the resulting seeds are harvested. What traits would you expect in the plants grown from these seeds? A. All of the offspring plants will have purple stems. B. All of the offspring plants will have green stems. C. About half of the offspring plants will have purple stems, and half will have green stems. D. Most of the offspring plants will have purple stems, but some will have green stems.
Answer:
D. Most of the offspring plants will have purple stems, but some will have green stems.
Explanation:
These plants are heterozygous, which means that they have two different alleles of the same gene. One allele, the ANL one, is going to dominate over the other resulting in purple-stemmed plants, which is the color that ANL encodes for.
If we draw a Punnet Square, we can see that the majority of the offsprings will have purple stems, but some of them, the ones that have two recessive alleles, will have green stems.

What is an ecosystem and what does it consist of?
Answer:
An ecosystem is a large community of living organisms (plants, animals and microbes) in a particular area. The living and physical components are linked together through nutrient cycles and energy flows. Ecosystems are of any size, but usually they are in particular place. An ecosystem consists of the biological community that occurs in some local, and the physical and chemical factors that make up its abiotic(non-living) environment. There are many examples of ecosystems -- a pond, a forest, an estuary, a grassland.

which of the following steps happens first during transcription?
Answer:
RNA polymerase attaches to the promoter.
Explanation:i just did it
The following steps happen first during transcription: the RNA polymerase reaches the beginning of a gene that is the second option (B), as the beginning of a gene is the promoter.
What is the significance of the transcription initiation?Transcription initiation has many implications, such as the fact that prokaryotic initiation is different from eukaryotic initiation, where the RNA polymerase first binds at the promoter site of the gene, where it starts moving towards the gene, and then after reaching the termination site, the transcription stops. In this process, the final product is mRNA from DNA.
Hence, the following steps happen first during transcription: the RNA polymerase reaches the beginning of a gene that is the second option, as the beginning of a gene is the promoter.
