Answer:
Rainbow Parrot Fish
Explanation:
Rainbow Parrot Fish is an herbivore and it is considered as competitor of corals and a direct threat to coral reef because Rainbow Parrot Fish majorly source of feed is algae which result in missing of lots of algae in corals colony. They consume most of the coral in the coral reefs with their beak like teeth therefore resulting in competition and not enough available algae source for corals. After feeding on algae , they also graze on corals in Coral reefs.

what structures are found in every living cell
Answer:
The parts include a plasma membrane, cytoplasm, ribosomes, and DNA.
Explanation:
The structures found in every living cell are:
Plasma membraneCytoplasmDNACells are the smallest anatomical unit of organisms that perform all the characteristic functions of living beings, their structures are functionally related in order to keep the cell alive and reproduce it.
The outer limit of the cell is the plasma membrane.
It has two basic functions:.
• Receive signals from the environment or from other neighboring cells.
• Be a selective barrier of substances, allowing to concentrate those that the cell needs for its metabolism and to eliminate its waste.
The cytoplasm is the compartment found inside the plasma membrane, which consists of an aqueous substance in which various molecules and macromolecular complexes are immersed, as well as different types of organelles.
All living cell store in the form of DNA, deoxyribonucleic acid, the information necessary to control their activities (reproduction, metabolism), and to establish their own structure. DNA is a polymer formed by a linear sequence of monomers, called nucleotides.
Therefore, we can conclude that the main structures found in every living cell are the plasma membrane, and the compartment that it encloses, called cytoplasm, which contains the hereditary material (DNA), where cellular activities are governed.

Explanation:
what kind of bond forms when atoms in a molecule do not share their electrons equally
a. an ionic bond
b. a metallic bond
c. a polar bond
d. a hydrogen bond
Answer:
A polar bond
Explanation:
Ionic bond don't share but one atom accepts electron while the other gives away electron Metallic bond are held by metals and they contribute their outer valency electrons to the electron cloud thus making them positive A polar bond deals with the share of unequal electron (I.e. Covalent polar bond) A hydrogen bond is covalently bonded to highly electronegative elements of small atomic sizeWhich of those ancient populations is the most likely to have contributed significantly to the bottleneck effect in the YDNA variation observed across much of Eurasia?
1. Yamnaya
2. Denisovans
3. Basal Eurasians
4. Ancient North Eurasians
5. Gravettians
Answer:
The correct answer is "Yamnaya".
Explanation:
In genetics, a population or genetic bottleneck is defined as a reduction on the size of a population as a result of an environmental effect or human intervention. Regarding the Y chromosome bottleneck, the Yamnaya is an ancient population that contributed the most due to its sex-biased and stratified culture. The Yamnaya were violent and left behind many male skeletons, where just few type of persons were able to reproduce.

ANSWER ASAP PLEASE Explain the meaning of the term "soil taxonomy," using taxonomic examples to illustrate application of the field.
Answer:
Soil in this text is a natural body comprised of solids
(minerals and organic matter), liquid, and gases that occurs
on the land surface, occupies space, and is characterized by
one or both of the following: horizons, or layers, that are
distinguishable from the initial material as a result of additions,
losses, transfers, and transformations of energy and matter or
the ability to support rooted plants in a natural environment
(Soil Survey Staff, 1999). This definition is expanded from the
previous version of Soil Taxonomy (Soil Survey Staff, 1975) to
include soils in areas of Antarctica where pedogenesis occurs
but where the climate is too harsh to support the higher plant
forms.
The upper limit of soil is the boundary between soil and
either air, shallow water, live plants, or plant materials that
have not begun to decompose. Areas are not considered to have
soil if the surface is permanently covered by water too deep
(typically more than about 2.5 m) for the growth of rooted
plants. The horizontal boundaries of soil are areas where the soil
grades to deep water, barren areas, rock, or ice. In some places
the separation between soil and non soil is so gradual that clear
distinctions cannot be made.
The lower boundary that separates soil from the non soil
underneath is most difficult to define. Soil consists of the
horizons near the earth’s surface that, in contrast to the
underlying parent material, have been altered by the interactions
of climate, relief, and living organisms over time. Commonly,
soil grades at its lower boundary to hard rock or to earthy
materials virtually devoid of animals, roots, or other marks
of biological activity. The lowest depth of biological activity,
however, is difficult to discern and is often gradual. For
the practicality of soil survey, the lower boundary of soil is
arbitrarily set at 200 cm. In soils where either biological activity
or current pedogenic processes extend to depths greater than
200 cm, the lower limit of the soil for classification purposes
is still 200 cm. In some instances the more weakly cemented
bedrocks (paralithic materials, defined later) and uncemented
bedrocks (some densic materials, defined later) have been
described below the lower boundary of soil and used to
differentiate soil series (series control section, defined in chapter
17). This is permissible even though the paralithic materials
below a paralithic contact are not considered soil in the true
sense. In areas where soil has thin, pedagogically cemented
horizons that are impermeable to roots, the soil extends as
deep as the deepest cemented horizon, but not below 200 cm.
For certain management goals, layers deeper than the lower
boundary of the soil that is classified (200 cm) must also be
described if they affect the content and movement of water and
air or other interpretative concerns.
In the humid tropics, earthy materials may extend to a depth
of many meters with no obvious changes below the upper 1 or
2 m, except for an occasional stone line. In many wet soils,
gleyed soil material may begin a few centimeters below the
surface and, in some areas, continue down for several meters
apparently unchanged with increasing depth. The latter
condition can arise through the gradual filling of a wet basin
in which the A horizon is gradually added to the surface and
becomes gleyed beneath. Finally, the A horizon rests on a thick
mass of gleyed material that may be relatively uniform. In both
of these situations, there is no alternative but to set the lower
limit of soil at the arbitrary limit of 200 cm.
Soil, as defined in this text, does not need to have discernible
genetic horizons, although the presence or absence of genetic
horizons and their nature are of extreme importance in soil
classification. Plants can be grown under glass in pots filled
with earthy materials, such as peat or sand, or even in water.
Under proper conditions all these media are productive for
plants, but they are non soil here in the sense that they cannot
be classified in the same system that is used for the soils of a
survey area, county, or even nation. Plants even grow on trees
or in cracks of exposed bedrock (i.e., rock outcrop), but trees
and rock outcrop are regarded as non soil.
Soil has many temporal properties that fluctuate hourly,
daily, and seasonally. It may be alternately cold, warm, dry,
or moist. Biological activity is slowed or stopped if the soil
becomes too cold or too dry. The soil receives additions of
fresh, undecomposed organic matter when leaves fall or grasses
die. Soil is not static. The pH, soluble salts, amount of organic
matter and carbon-nitrogen ratio, numbers of microorganisms,
soil fauna, temperature, and moisture status all change with
the seasons as well as with more extended periods of time.
Soil must be viewed from both the short-term and long-term
perspective.

Some benefits of dietary fiber are build muscle and flexibility.
True or False
Answer:
true
Explanation:
dietary fiber build muscle and flexibility
Dietary fiber is one of the components of a nutrient and balanced diet. Dietary fiber in the diet can build muscle and flexibility. Thus, the statement is true.
What is dietary fiber?Dietary fiber along with the functional fibers makes the total fiber that makes part of the diet and is considered to be nutritious. They are homopolysaccharides that are made of various similar monomers linked concurrently by the glycosidic linkage.
Dietary fiber is composed of various units of cellulose linked chemically by the beta (1 - 4) glycosidic linkage. They have been known as roughage which are plant parts that are undigestable. Though they cannot be absorbed, but they ensure a smooth digestive and excretory process.
The presence of dietary fiber in the diet increases flexibility and muscle mass by decreasing body fat and is found in beans, broccoli, avocados, berries, apples, etc. It eliminates fats and other wastes from the body by promoting regular bowel movements.
Therefore, the statement is true.

Which of the following ways are leftover neurotransmitters cleaned up if they
have not been accepted by the postsynaptic neuron?
Pick 2
the neurotransmitters are broken down in the synapse
the postsynaptic neuron absorbs the neurotransmitters
The presynaptic neuron absorbs the neurotransmitters
the neurotransmitters are built up to create a new neuron
Answer:
The correct answer is -
the neurotransmitters are broken down in the synapse
The presynaptic neuron absorbs the neurotransmitters
Explanation:
The termination of the neurotransmitters is essential as if they can cause harm by continuing the stimulus effect on the muscles or cells. To clean up these neurotransmitters there are two ways- Degradation of neurotransmitters with the help of enzymes in the synapses or synaptic cleft and the presynaptic neurons absorbs or suck up neurotransmitters. The neuron (presynaptic neuron) is that releases the neurotransmitter like dopamine, serotonin, is the one that re-uptake it.
This reuptake is done by transporter proteins that are are symporters in nature as these proteins pump neurotransmitters as well as ions back into the neuron.
