Net primary productivity is the amount of organic material that is available for transfer to the next trophic level after subtracting material used for respiration.
When a plant is eaten by a mouse, the mouse is consumed by a snake, and the snake is in turn consumed by a hawk. In this case, there will be less organic matter available.
Biomass change from lower to higher trophic levels by decreasing.
The incomplete burning of ethanol in gasoline is known to create black carbon and contribute to global warming.
There is less secondary consumers in an ecosystem than producers because there isn’t enough energy available to support more secondary consumers.
It should be noted that global warming brings about the increase in the temperature around the world.

Explanation:
tRNA molecules deliver amino acids to ribosomes where the amino acid next
A. forms an ionic bond with another amino acid
B. is deaminated and catabolized
С. becomes an anticodon
D. is covalently bonded to a growing polypeptide
E. forms hydrogen bonds with esters
Answer:
tRNA molecules deliver amino acids to ribosomes where the amino acid next becomes an anticodon (option C).
Explanation:
A tRNA molecule is able to deliver amino acids to the ribosomes for protein synthesis, forming an anticodon that complements the codon of the mRNA being translated. The mRNA molecules are responsible for conducting the genetic code —obtained from DNA transcription— to be translated by the ribosomes. This code is established by sequences of three nucleotides, called codons, which encode different amino acids.
What happens when mRNA molecules expose codons to ribosomes is that a tRNA molecule containing a complementary anticodon is formed, which is conducted to the ribosome to bind to the codon. This allows, according to the genetic code, the formation of a protein with a specific sequence of amino acids.
tRNA molecules deliver amino acids to ribosomes where the amino acid - С. becomes an anticodon.
During translation tRNA, molecules deliver amino acids to the ribosome and bind to this codon. It is a complementary anticodon to this codon.
Each tRNA molecule has two distinct endsone end binds to a specific amino acidthe other which binds to the corresponding mRNA codon. The first tRNA transfers its amino acid to the amino acid on the newly arrived tRNA, and a chemical bond is made between the two amino acids.Thus, tRNA molecules deliver amino acids to ribosomes where the amino acid - С. becomes an anticodon.

In the testes, sperm cells replicate and differentiate in the _________. Question 2 options: urethra septum tunica albuginea seminiferous tubules ductus deferens
Answer:
seminiferous tubules
Explanation:
Seminiferous tubules are coiled tubes where sperm cells are produced by a process referred to as spermatogenesis. These tubes are located in the testes or testicles (i.e., male reproductive glands/gonads). Each testicle contains approximately 250 compartments known as testicular lobules, while each testicular lobule has 1 to 4 seminiferous tubules which converge to form a single straight tubule. Once sperm cells mature, they travel through the seminiferous tubules to be stored in a coiled tube called the epididymis.

Answer:
Mechanical waves react to different mediums in different ways. Some mechanical waves are TRANSMITTED through a medium, meaning they pass through the medium.
The way in which waves are transmitted depends upon the type of material. In SOLIDS, mechanical waves travel rapidly, because the molecules are DENSELY packed. In liquids and air, however, mechanical waves travel more SLOWLY, because the molecules are spread farther apart.
Other mechanical waves are reflected off a medium. When a mechanical wave is reflected, it BOUNCES off the medium and then travels in a DIFFERENT direction. SONAR is an application that uses sound wave reflection to determine how deep water is.
A third way mechanical waves react to a medium is ABSORPTION. When a mechanical wave is absorbed, it remains WITHIN a medium and is not transmitted to another medium.

Explanation:
Fred has inherited the colorblind trait from his mother. We know this because his spot on the pedigree is filled in. Because he is a male his genotype must be some variation of xy and because he is colorblind he must have the recessive "h" on his x chromosome. So his genotype (genetic type) is [tex]x^{h} y[/tex]

How do mutations affect natural selection
Answer:
The idea of natural selection would in theory be affected by mutations because natural selection invloves a species/animal only surviving by having a certain trait. Over time, all of the animals/species would have this trait through elimination partnered with reproduction. A mutation may begin this cycle by giving an animal the ability to have an advantage over its fellow species.
Explanation:
Answer:
They affect how likely an organism is to survive and reproduce

1. A dominant gene (A) causes yellow color in rats, the dominant allele on another independent gene (R) produces black coat color. When the two dominants occur together (A_ R_) they interact to produce gray coat color. Rats of the genotype aa are cream-colored. If a gray male and a yellow female, when mated, produce offspring approximately 3/8 of which are yellow, 3/8 gray and 1/8 cream, and 1/8 black, what are the genotypes of the parents
Answer:
Parents: Yellow (Aarr) and Grey (AaRr)
Explanation:
Given:
allele A = yellow
allele R = black,
Heteroozygous = gray
Genotypes of the parents:
yellow (Aarr) - female
gray (AaRr) - gray
cross between these
Parents: Yellow (Aarr) and Grey (AaRr)
Gametes: (Ar, ar) and (AR, Ar, aR, ar)

hypothesis on what is the effect of the genes of the parental mice on the fur color of the offspring mice? use "If...then...format
Answer:
If the GENES of the parental mice encodes for a black fur, THEN the FUR COLOR of one of the offspring mice will be black.
Explanation:
Hypothesis is one of the steps used in the scientific method. It is a testable explanation of a given question or observation. Hypothesis in an experiment must be subjected to testing via experimentation in order to determine whether to reject it or not.
Hypothesis is usually constructed in the IF, THEN format. It tells us how the independent variable (cause) affects the dependent variable (outcome). In this case, a question is asked this: "what is the effect of the genes of the parental mice on the fur color of the offspring mice?"
A possible hypothesis will be: If the GENES of the parental mice encodes a black fur, THEN the FUR COLOR of one of the offspring mice will be black.
Answer:
A. If either parent mouse passes a dominant allele, the offspring will have black fur.
Explanation:
Either option is correct because it didn't show any green check. It determines on what hypothesis you wrote. I chose A because it relates to my statement. <33
If there will be changes on trophic levels, what will be the effects on the ecosystem?
Answer:
It can significantly alter the homeostasis of the ecosystem
Explanation:
The trophic level is the position that occupies a given organism/ population/species in the food web. In a food web, the trophic levels are organized into a first category (formed by primary producers, e.g., plants), a second level (primary consumers, e.g., herbivores), and subsequent categories (predators, e.g., carnivores). The abrupt change in the number of organisms belonging to the same trophic level generally has a negative effect on the ecosystem by modifying the trophic structure of communities. For example, decreasing the number of producers will produce a decrease in the number of primary consumers, thereby altering the homeostasis (equilibrium) of the entire ecosystem. On some occasions, it may eventually lead to the extinction of populations and species.

Answer:
The correct answer is - b. inadequate mineralization in the osteoid.
Explanation:
Osteomalacia is a condition where the bones become weak and soft, this bone softening is occurred due to mainly vitamin D deficiency that also causes rickets. It leads to insufficient or inadequate mineralization in the osteoid.
This conditing when takes place in kids and young adult leads to curve or bowing during the growth period. In this case, bones are very prone or easily fractured.
