Answer:
The smell is one of the senses that is created by the small molecules that are released by the food, aromatic substance, or any substance into the air. When we inhale during the breathing process these small molecules enter our nose and trap in tiny hair of the nose.
These molecules dissolves in mucus present in the nose to reach the specialized receptor cells known as olfactory receptor neurons. These neurons detect the smells and send the information directly to the brain to the olfactory bulbs that work to detect the smell.

What happens after the gated channels close?
Answer:
Explanation:
After the gated channels close, which is as a result of depolarization of voltage, the positive charge that has been increased in the cell will make the potassium channels to open and this will gush out of the cell through its electrochemical gradients. When potassium ion move out of the cell, the membrane potential begin to get to resting potential.
If the frequency of the disorder in the population is 0.0070, what is the percentage of heterozygous carriers
Answer:
15.322 %
Explanation:
Supposing that this is a recessive disorder and the population is in Hardy-Weinberg equilibrium:
p² + 2pq + q² = 1, where
1- the genotypic frequency of the homo-zygous dominant allele is p²,
2- the genotypic frequency homo-zygous recessive allele is q², and
3- the genotypic frequency heterozygous allele is 2pq
Therefore:
q² = 0.007 >> q = √ 0.007 = 0,0836
p = 1 - q = 1 - 0,0836 = 0.9164
2pq = 2 x 0.9164 x 0,0836 = 0.15322 (or 15.322 %)
Which of these ideas would be the best course of action for decreasing land temperatures?
Answer:A
Explanation:
When large masses of magma solidify far below Earth’s surface, they form igneous rocks that have a _____.
Answer:
coarse-grained texture
Explanation:
Igneous rocks come from magma of volcanos and they cool and end up becoming hard. A perfect example of this is granite, which contains a lot of minerals such as quartz and feldspar. Igneous rocks contain a lot of minerals hence why they have a coarse-grained texture.

Which of these is a characteristic of index fossils? (7 points) a Found in the topmost rock layer b Found in many layers of the same rock c Have already established relative age d Are limited to a particular geographic location
Answer:
it is in fact relative age
Explanation:
Have already established relative age is a characteristic of index fossils.
What do you mean by index fossils?
Index fossils are fossils used to define and identify geologic periods. Index fossils must have a short vertical range, wide geographic distribution and rapid evolutionary trends.
A good index fossil is one with four characteristics: it is distinctive, widespread, abundant, and limited in geologic time. Because most fossil-bearing rocks formed in the ocean, the major index fossils are marine organisms.
Index fossils are the preserved remains of specific species found in the strata of sedimentary rock. They are easily recognized by shape and lived for either a short period of time, geologically speaking, or completely vanished from the Earth in a known extinction event.

Because oxygen is circulated throughout the body via the bloodsteam, there is a strong connection between the cardiovascular system and the ________________ system.
Group of answer choices
respiratory
digestive
endocrine
nervous
Answer:
Because oxygen is circulated throughout the body via the bloodstream, there is a strong connection between the cardiovascular system and the respiratory system.
Explanation:
The cardiovascular system is responsible for the transport of oxygen to all tissues of the body, in addition to the removal of carbon dioxide, which depends on the close interaction with the respiratory system.
A summary of the strong connection between the cardiovascular and respiratory systems is :
Blood contains red blood cells, which are responsible for transporting O₂ and CO₂ by binding to the hemoglobin molecule, present in these structures. The respiratory system is responsible for providing air with O₂ and removing CO₂, a process that depends on gas exchange at the level of the pulmonary alveolus.

Answer:
The answer should be A. lithosphere.
Explanation:
Firstly, let's look at the options:
C. and D, both parts of the Earth at the core, have almost nothing to do with the Earth's crust or tectonic plates except maybe having a passive effect on them.
B. mantle is where the lava that moves the tectonic plates circulates due to convection, which is the reason they move at all. But, it is not where the tectonic plates themselves are.
Therefore, finally, we have A as the answer.
(As a sidenote, the "lithosphere" means the Earth's crust.)

Pickling has been used to preserve foods for over 4000 years. Research how foods are pickled and relate your experimental results to this preservation technique.
Answer:
by increasing food acidity, thereby microorganisms cannot survive.
Explanation:
Pickling can be defined as the techniques used to preserve and extend food shelf life of food by increasing acidity, which is achieved by using vinegar or by brine fermentation, i.e., by bacteria that increase acidity when they produce acid lactic. In consequence, foods that serve as a microhabitat for microorganisms that affect their shelf life cannot survive and grow. The foods treated by pickling may take a different coloration, taste, texture, etc. The time of this process varies depending on the applied technique from hours to many days (or longer).

What is the relationship between the distribution of coral polyps and the population
density of plankton in the water?
a. Coral polyp distribution is independent of plankton density because they live in different geographical locations.
b. If there is a high density of plankton in the water, then there will be a high coral polyp distribution.
c. If there is a high density of plankton in the water then there will be a low coral polyp
distribution.
d. The relationship between coral polyp distribution and plankton density is limited because they have different food sources.
Answer:
Coral polyps and zooxanthellae algae live in a symbiotic relationship to create coral reefs. The polyps give shelter to the algae while the algae create food for the polyp by photosynthesis. Therefore, the higher the density of phytoplankton, the higher the density of coral polyps.

Explain the ranking of the rate of photosynthesis in the basil plants caused by each light source
Explanation:
White light appears to be the most effective light for photosynthesis, but apart from white, red light is also effective. When white light is not used, red is more effective than its counterparts, most likely because red light has a long wavelength that allows it radiate more energy and heat than other color.

A population has 1000 individuals. A PCR analysis of the genotypes of a gene associated with Lactase persistence are: LL = 450 Ll = 250 ll = 300. What are the allelic frequencies of the L and l alleles?
Answer:
L allele: 0.575 (or 57.5%)
l allele: 0.425 (or 42.5 %)
Explanation:
Homo-zygous individuals have two copies of the same allele (i.e., either L alelle or l allele), while heterozygous individuals carry both alleles at a time (i.e., one L allele and one l allele). In consequence:
- Frequency of the L allele: [(450 x 2) + 250] / 2000 = 0.575
- Frequency of the l allele: [(300 x 2) + 250] / 2000 = 0.425

The illustration shows one of the ways resources are removed from the deep sea. Describe what type of resources these are, including if they are renewable or non-renewable. Predict two consequences to the seafloor life if this process is not regulated.
Answer:
Marine mining is a process that can be done by dredging the seabed and is used for the extraction of mineral resources from the seabed, which are non-renewable, with a negative impact on marine ecosystems.
Explanation:
The illustration shows a process of marine mining by dredging, where the resource extracted is of a mineral nature, like copper, zinc, silver and gold. Gravel used for construction can also be extracted from the sea. Mineral resources extracted from the sea are not renewable.
The process of marine mining can be harmful to the ecosystems there, so it must be a process that requires control and management from the ecological point of view.
Two possible consequences of not regulating marine mining are:
Destruction of the habitat of life forms present on the sea floor, which endangers many species and even forces migration to more stable areas, with consequences on the food chains.Extinction of marine species that inhabit the seabed. The flora and fauna of the sea floor usually have slow reproductive cycles and, in the case of fish, spawning takes place on the bottom of the sea. Mining endangers the reproductive cycles of the species, leading to induced extinction.Responsible and controlled mining activity can be useful for humans, while avoiding negative consequences on the ecosystems that exist at the seabed.
Why do fishes die when they are taken out?
Answer:
Fishes take oxygen through their gills. Gills are richly supplied with blood capillaries and can readily absorb oxygen dissolved in water. Gills of fishes are not equipped to take in gaseous oxygen (oxygen from air). Hence, a fish when taken out of water is unable to inhale oxygen rich air and so, dies quickly.

Explanation:
S. cerevisiae occurs in nature on ripe fruit. S. epidermidis naturally occurs on human skin. How do experimental results relate to the natural environment of each microbe?
Answer:
S. cerevisiae needs natural environment present on ripe fruit while S. epidermidis needs natural environment present on human skin.
Explanation:
S. cerevisiae occurs in nature on ripe fruit because the environment is suitable for them that provides food in the form of sugar while S. epidermidis naturally occurs on human skin because it needs wet and humid environment which is available on human body such as armpits. Due to the presence of suitable environmental condition, both S. cerevisiae and S. epidermidis are present on fruits and human skin respectively.
