The intensity of sunlight on Earth is affected by
A.) the mass of Earth
B.) the speed of Earth
C.) the number of rotations of Earth
D.) the curved surface of Earth
Answer:
The correct answer is D.) the curved surface of Earth.
Explanation:
The intensity of sunlight on Earth is affected by the curved surface of Earth, which causes the sunlight to spread out over a larger area. As a result, the intensity of sunlight is less at any given point on Earth's surface than it would be if Earth had a flat surface. This also explains why the poles receive less sunlight than the equator, as sunlight is spread out over a larger area near the poles due to the curvature of the Earth.
Factors such as the mass of Earth, the speed of Earth, and the number of rotations of Earth do not directly affect the intensity of sunlight on Earth.

Suppose the DNA sequence GCT ATA TCG was changed to GCTАТТ TCG. How would the products of translation, the amino acids, be affected ?
Answer:
The outcome of a frameshift mutation is complete alteration of the amino acid sequence of a protein. This alteration occurs during translation because ribosomes read the mRNA strand in terms of codons, or groups of three nucleotides. ... Each word itself has a separate meaning, as each codons represents one amino acid.
Explanation:
hope it helps.
have a wonderful day!
In the given DNA sequence GCT ATA TCG, the second codon is changed from ATA to АТТ.
This change would affect the products of translation, which are the amino acids. To determine the amino acids, we need to refer to the genetic code, which translates each codon into a specific amino acid. The codon ATA corresponds to the amino acid isoleucine (I), while the codon АТТ also corresponds to isoleucine (I).
Since both codons, ATA and АТТ, code for the same amino acid (isoleucine), the change in the second codon would not affect the amino acids produced during translation. Therefore, the products of translation, the amino acids, would remain unaffected by this change.

Which of these hormones would be able to cross the plasma membrane by simple diffusion?
a) insulin—a protein
b) hormone epinephrine—a biogenic
c) amine hormone testosterone—a steroid hormone
Testosterone, being a steroid hormone, is able to cross the plasma membrane by simple diffusion due to its lipid-soluble nature. Hence option (c) is correct.
Of the hormones mentioned, the hormone that would be able to cross the plasma membrane by simple diffusion is testosterone. Testosterone is a steroid hormone, and steroid hormones are able to diffuse across the plasma membrane due to their lipid-soluble nature.
The plasma membrane is composed of a lipid bilayer, which acts as a barrier to prevent the entry of hydrophilic molecules. However, lipid-soluble molecules are able to pass through the plasma membrane easily by dissolving in the lipid bilayer.
Epinephrine, on the other hand, is a biogenic amine hormone. Biogenic amine hormones are not lipid-soluble, and therefore cannot cross the plasma membrane by simple diffusion. Instead, they bind to specific receptors on the plasma membrane and trigger a cellular response through a signal transduction pathway.
In summary, testosterone, being a steroid hormone, is able to cross the plasma membrane by simple diffusion due to its lipid-soluble nature. Epinephrine, a biogenic amine hormone, cannot cross the plasma membrane by simple diffusion and relies on specific receptors to elicit a response.

What is primary productivity?
A. the amount of sunlight that a plant receives
B. the rate at which organic matter is created by
producers
C. the amount of producers in a certain
ecosystem
Gross primary productivity is the total amount of organic matter that producers synthesize in the course of photosynthesis per unit of time and per unit of space (GPP).
In tropical regions, primary productivity is high and consistent throughout the year, but it is constrained by a cold temperature and a short growing season in temperate regions.
The tropics have the most sunlight, whilst the poles have the least. Due to this, net primary production (NPP) is highest in the tropics (>20 t ha 1 year) as opposed to the average (8 t ha 1 year) in temperate forests.
The synthesis of organic compounds from atmospheric or aqueous carbon dioxide is referred to as primary production in ecology.
Water for which productivity is to be assessed is confined in sealed white and dark bottles. Primary productivity can be measured from the amount of oxygen utilized by a volume of water in a defined amount of time (bottle painted dark so light would not enter).
Primary production, the lowest trophic level, provides vital nutrients and energy to higher trophic levels and higher organisms because it is the lowest trophic level.

which of the following best describes our current understanding of the possibility of fast interstellar travel by entering and leaving hyperspace?
Currently, our understanding of the possibility of fast interstellar travel by entering and leaving hyperspace is speculative and largely rooted in science fiction rather than scientific evidence.
While the concept of hyperspace travel has captured the imagination of many, there is no empirical evidence or widely accepted scientific theory supporting its existence or feasibility.
Hyperspace, as depicted in science fiction, is often portrayed as an alternate dimension or a shortcut through space-time that allows for faster-than-light travel. However, according to our current understanding of physics, the speed of light is considered an absolute speed limit, and traveling faster than light would violate the principles of relativity.
Although scientific theories such as wormholes and warp drives have been proposed as potential mechanisms for interstellar travel, they are largely speculative and theoretical concepts that require exotic forms of matter and energy that have not been observed or confirmed.
In conclusion, while the idea of fast interstellar travel through hyperspace is captivating in science fiction, it remains a concept that is not supported by current scientific understanding or empirical evidence.

Nitrogen oxides released into the atmosphere by burning fossil fuels and organic matter is not a source of nitrogen which is available to plants. Thus, the correct option is D.
How does plants take nitrogen?Plants require nitrogen as it is a macronutrient. The deficiency of this nutrient can cause many diseases. However, plants cannot themselves obtain the nitrogen from air but they rely mainly on the supply of combined nitrogen atom in the form of ammonia molecule, or nitrate molecule, resulting from the nitrogen fixation through free-living bacteria in the soil or the bacteria living symbiotically in the nodules on roots of legumes.
Plants can take nitrogen through absorbing the soil by their roots. Plants cannot get this nitrogen directly from the air. Although, the nitrogen element is abundantly available in air. Nitrogen is unreactive atom, and it cannot be used by the green plants to make proteins. Nitrogen gas needs to be converted into nitrate compounds in the soil through nitrogen-fixing bacteria in soil, root nodules or lightning. Every nitrogen atom is triple-bonded to another nitrogen atom to form the molecular nitrogen, N₂.
