Explain why animals are dependent on light energy
Answer:
Animals are dependent for multiple reasons.
Explanation:
The energy is transferred to animals when they eat plants. They also need it because vitamin D is given when animals get sunlight on their bodies, building strong bones and healthy marrow. The same happens when they eat vitamin D-rich plants. Hope this is helpful!
Which is a possible outcome for future generations of farmers if the same crop is planted on the same patch of land every year?
the soil could become infertile due to the lack of time for nutrients to be reinserted
the crops could become resistant to pests and insects through natural selection
the soil could become drought resistant due to the shallow root structure that would form
the crops could begin to change their genetic makeup due to mutations from the parent plants
Answer:
A
Explanation:
I hope this helps :)
The soil could become infertile due to the lack of time for nutrients to be reinserted. So, the correct option is (A).
What is Soil?Soil is also defined as earth or dirt which is a mixture of organic matter, minerals, gases, liquids and organisms which together support life. These are distinguished from silt by restricting the former term specifically to displaced soil.
It provides many important services for both people and the planet by putting food on our plates, purifying our water, protecting us from floods and combating drought. Soil is also important in combating climate change because it captures and stores large amounts of carbon. Without healthy soil there is no food security.
Whereas growing the same crop year after year reduces the availability of certain nutrients and depletes the soil. Monoculture leads to soil exhaustion when the soil becomes deficient in these nutrients.
Thus, the soil could become infertile due to the lack of time for nutrients to be reinserted. So, the correct option is (A).

Plasmodium is an organism with both sexual and asexual life cycles. Describe the most likely cause of a heritable phenotypic change in some members of a population of asexually reproducing organisms. Explain how repeated exposure of the artesunate-sensitive Plasmodium strain to increasing concentrations of artesunate led to the development of the artesunate-resistant Plasmodium strain.
Answer:
Mutation.
Explanation:
Mutation in the organism's DNA that is passed on to the offspring is that main cause of heritable phenotypic change in some members of a population that reproduces asexually. Repeated exposure of Plasmodium that is sensitive to artesunate strain to increasing dosage of artesunate led to the development of resistance in plasmodium because the genetic mutation occur in the plasmodium that provide resistance against artesunate.
A unicellular eukaryotic organism that infects and lives in insects and vertebrates as a parasite is called plasmodium. They are single-celled organisms that undergo both types of reproductive life cycles.
The mutation caused a heritable phenotypic change in some members of a population of certain type of reproducing organisms.
The mutation in the plasmodium strain can be explained as:Some organisms of certain reproducing type happened to be mutated causing a heritable phenotypic change in their offspring's. When the plasmodium strain was repeatedly exposed to artesunate which altered some of the species in becoming resistant instead of being sensitive.The increased dosage or exposure caused a mutation in some type of certain reproducing strains causing them to be resistant to the amount.Therefore, the mutation caused the heritable phenotypic change.

An acoustic neuroma is a tumor that arises from neurolemmocytes surrounding the vestibular portion of the vestibulocochlear nerve. The tumor is benign, but generally grows within the confined space of the petrous part of the temporal bone, thus compressing the nerve and creating problems with balance and hearing loss. What other, nearby nerve would you expect to also be affected by this tumor
Answer: The nearby nerve that can be affected by this tumour is the FACIAL NERVE.
Explanation:
As stated in the question, the acoustic neuroma is a tumor that arises from the vestibular portion of the vestibulocochlear nerve which is the VIII ( 8th) cranial nerve.
VESTIBULOCOCHLEAR NERVE: These nerves are composed of two distinct sets of fibres, vestibular nerves and cochlear nerves.
The vestibular nerves arise from the semicircular canals of the inner ear and convey impulses to the cerebellum. They are associated with the maintenance of posture and balance. The cochlear nerves originate in the spiral organ in the inner ear and convey impulses to the hearing areas in the cerebral cortex where sound is perceived.
The Facial nerve, also called the 7th cranial nerve, which are the motor fibres that supply the muscles of facial expression. It lies adjacent to the vestibulocochlear nerve as they pass through the internal auditory canal which is located at the petrous part of the temporal bone. As the tumor grows, the facial nerve would be affected because it's the closest nerve to the VESTIBULOCOCHLEAR nerve..

All camels are basically similar in structure. They have developed adaptations for coping with both heat and dehydration.
Which of the following does not benefit the camel as a means of preventing dehydration?
a.Camels can extract water from their solid wastes.
b.Camels' ears are lined with fur to keep out sand and other blowing matter.
c.Their kidneys are capable of concentrating urine to reduce water loss
d.Camels are able to locate water in any environment.
Answer: b
Explanation:
Camels ears are lined with fur to keep out sand and other blowing matter
The Cambridge family includes the unusually shaped Arabian camel (Camelus dromedarius), also referred to as the one-humped camel. This animal is perfectly suited to the harsh desert climate and high levels of heat stress. Thus, option B is correct.
What camels are adaptations for heat and dehydration?Camels have evolved to survive in extremely hot and cold climates.In contrast to many other mammals, camels store the majority of their body fat in their humps, which allows for better thermoregulation. It makes it easier for them to release heat from their body in hotter climates. Camels rarely perspire.
Camels are ideally suited for desert survival. They have developed wide, flat feet to disperse their weight across the sand, among other adaptations. Thin fur everywhere to allow for rapid heat loss, and dense fur on the top of the body for shading.
Therefore, The kidney may be able to retain water if the generation of cholesterol is reduced. Camels produce pee that is highly concentrated, retaining the maximum amount of water.

Invert syrup is a widely used sweetener, especially in candies and highly processed foods. Invert syrup can be made by treating sucrose with either an enzyme called sucrase or by heating sucrose with an acid. The end result is the same: each molecule of sucrose is hydrolyzed, resulting in _
Answer:
one glucose and one fructose molecule
Explanation:
Generally, inverted sugar is a mixture of two monosaccharides or simple/reducing sugars. More specifically, inverted sugar is a mixture of glucose and fructose.
Sucrose is a disaccharide containing one molecule of glucose and one molecule of fructose. Hence, when hydrolyzed, the glycosidic bond linking the glucose molecule with the fructose molecules becomes broken and the resulting product is a mixture of glucose and fructose molecules in equal proportions.
What is the process by which new oceanic crust is?
Explanation:
Subduction happens where tectonic plates crash into each other instead of spreading apart. At subduction zones, the edge of the denser plate subducts, or slides, beneath the less-dense one. The denser lithospheric material then melts back into the Earth's mantle. Seafloor spreading creates new crust.
A phenotypic ratio of 9:4:3 is indicative of __________.
A. Codominance
B. Polygenic inheritance
C. Epistasis
D. Multiple alleles
Answer:
a
Explanation:
The phenotypic ratio is the depiction and the relation of the occurrence of the phenotype in the offspring. The phenotypic ratio of 9:4:3 indicates codominance. Thus, option A is correct.
What is codominance?Codominance is the inheritance where both the recessive and the dominant allele are expressed in the offspring independently to produce the individual with the expression of both the trait separately.
The blood group, eye color, roan cattle, flower colors, sickle-cell anemia, etc., are some examples that show the pattern of codominance. The phenotypic ratio suggests the occurrence of the physical traits in the offspring that are visible.
In codominance, the phenotypic ratio is 9:4:3 as both the traits possessing alleles are independently expressed in the next generation.
Therefore, 9:4:3 is the phenotypic ratio of codominance.

Why is DNA locked in the nucleus of the cell?
Answer:
Inside the nucleus lies the blueprint that dictates everything a cell will do and all of the products it will make. This information is stored within DNA. The nucleus sends “commands” to the cell via molecular messengers that translate the information from DNA.
Explanation:
Answer:
In organisms called eukaryotes, DNA is found inside a special area of the cell called the nucleus. Because the cell is very small, and because organisms have many DNA molecules per cell, each DNA molecule must be tightly packaged. ... Researchers refer to DNA found in the cell's nucleus as nuclear DNA.

bond forms between a hydrogen atom with a partial positive charge on one
molecule and another atom, such as oxygen, with a partial negative charge on an adjacent molecule.
Answer:
Due to difference in the values of electronegativities.
Explanation:
A covalent bond is formed between hydrogen atom with a partial positive charge on it and another atom, such as oxygen, have a partial negative charge on an adjacent molecule. This is because of the difference in the values of electronegativities. The hydrogen atom has lower electronegativity value as compared to oxygen so the shared pair of electron is slightly attracted by oxygen atom towards itself and formed partial positive charge on hydrogen and partial negative charge on oxygen atom.
