how many bands will be visible on the gel assuming all unprotected dna was cleaved?
Answers
The number of bands that will be visible on a gel after cleaving all unprotected DNA will depend on various factors such as the size and number of DNA fragments, the type of gel used, and the specific experimental conditions.
In general, DNA cleavage can result in the generation of multiple fragments of varying sizes. These fragments can then be separated on a gel using techniques such as agarose gel electrophoresis or polyacrylamide gel electrophoresis based on their size, with smaller fragments migrating faster through the gel and larger fragments migrating slower.
Assuming that all the unprotected DNA has been cleaved into fragments of different sizes, the number of bands visible on the gel would correspond to the number of different-sized DNA fragments generated. Each distinct size of DNA fragment will appear as a separate band on the gel, which can be visualized using techniques such as DNA staining or radioactive labeling.
Therefore, the total number of bands visible on the gel will depend on how many different-sized fragments were generated by the DNA cleavage, which can vary depending on the experimental conditions and the specific DNA being cleaved. A DNA ladder, which is a mixture of DNA fragments of known sizes, is typically included on the gel as a reference to estimate the sizes of the DNA fragments generated from the cleavage.

A) enzymes that are activated or inactivated by the hormone's second messenger.
B) enzymes that are activated or inactivated by the intracellular hormone-receptor complex.
C) an intracellular receptor protein that binds the hormone.
D) a cell-surface receptor protein that binds the hormone.
Answers
A target cell affected by a particular steroid hormone is expected to have intracellular receptor proteins that bind the hormone.
Steroid hormones are lipophilic and can diffuse across the plasma membrane. Once inside the target cell, the hormone binds to intracellular receptor proteins, forming a hormone-receptor complex. This complex then enters the nucleus and acts as a transcription factor, directly binding to specific DNA sequences and regulating gene expression. Consequently, the affected target cell experiences changes in enzyme activity and protein synthesis. Unlike peptide hormones, steroid hormones do not rely on second messengers or cell-surface receptors for their signaling. Therefore, option C is the correct answer, indicating that a target cell affected by a steroid hormone would have an intracellular receptor protein that binds the hormone.

The blue color of the sky results from the scattering of sunlight by air molecules.
Answers
Answer:
Yes
Explanation:
Sunlight is scattered by tiny air molecules (known as Rayleigh scattering) increases as the wavelength of light decreases. Violet and blue light have the shortest wavelengths and red light has the longest. Therefore, blue light is scattered more than red light and the sky appears blue during the day.
The sky appears blue to the human eye as the short waves of blue light are scattered more than the other colours in the spectrum, making the blue light more visible.

Cereals and legumes are complementary in the diet because Group of answer choices Cereals counteract the antinutritional factors in legumes A diet combining legumes and cereals will have a good balance of essential amino acids Cereals are high in lysine Legumes are high in cysteine and methionine
Answers
Answer:
A diet combining legumes and cereals will have a good balance of essential amino acids
Explanation:
Cereals are grains that are rich in vitamins, carbohydrates, protein and other essential nutrients, they include wheat, rice, sorghum etc. Legumes include a wide range of seeds, fruits, nuts, vegetables that are rich in proteins, carbohydrates and other nutrients, examples include peas, beans, lentils etc.
Cereals and legumes are referred to as staple foods, they are usually used to complement each other because combining them will result in a good balance of essential amino acids. In cereals, lysine is a limiting amino acid but is usually in high amounts in legumes. However, in legumes cysteine, trypthophan and methionine are the limiting amino acids but are found in cereals. Therefore, this makes legumes and cereals complementary in the diet as it significantly increases the protein quality of the diet.

Answers
Instinct is an unchanging, biologically inherited behavior pattern. When a marsupial is born, it climbs into its mother's pouch.
A living organism's natural propensity for a specific complicated behaviour, which includes both innate (inborn) and taught components, is known as instinct. A fixed action pattern (FAP), which is the simplest representation of an innate behaviour, is a very brief to medium-length sequence of unvarying actions that are carried out in response to a corresponding, well defined stimuli.
A hatchling leatherback turtle travels to the open ocean.
Any behaviour that is carried out without drawing on prior knowledge (i.e., in the absence of learning) is instinctive, and as a result, it is a manifestation of innate biological components. Sea turtle eggs laid on a beach will naturally drift toward the ocean when they hatch. When a marsupial is born, it climbs into its mother's pouch.

Why is the carrier selection process less straightforward than the modal selection process?
Answers
The carrier selection process is less straightforward than the modal selection process due to the complexities of assessing carrier status and the potential for individuals to carry recessive genetic mutations without displaying symptoms.
The carrier selection process is less straightforward than the modal selection process because it involves assessing an individual's carrier status for specific genetic conditions. Carriers are individuals who carry a single copy of a recessive genetic mutation but do not exhibit any symptoms of the associated disorder. In contrast, the modal selection process focuses on identifying individuals who display overt symptoms or characteristics of a particular condition.
Identifying carriers requires genetic testing and analysis to detect the presence of specific genetic mutations. This process can be complex as it involves analyzing an individual's DNA to identify the presence of recessive mutations that can be passed on to offspring. Furthermore, carriers may not have a family history of the condition or any symptoms, making it challenging to identify them without genetic testing.
In contrast, the modal selection process relies on visible characteristics or symptoms to identify individuals affected by a particular condition, making it relatively more straightforward.
